China Power Energy Solution Manufacturers, Suppliers, Factory

As renewable energy grows in popularity, the need for efficient energy storage solutions increases. Large-scale energy storage systems are currently being implemented to store excess electricity generated from renewable energy sources for use when generation is low. In addition to data centers and UPS power systems, Shangyu CPSY® power energy solutions also include emergency power supplies, electric vehicle charging piles and voltage regulators.

With the rapid advancement of society, the number of electrical equipment is increasing day by day. However, the aging and lagging development of power transmission and distribution facilities, as well as poor design and insufficient power supply, cause end-user voltages to be too low, while line-end users often have higher voltages. This is a problem for electrical equipment, especially high-tech and high-tech equipment with strict voltage requirements. Precision equipment is like a time bomb. As a public power grid, the mains power system is connected to thousands of various loads. Some of the larger inductive, capacitive, switching power supply and other loads not only obtain power from the grid, but also in turn cause damage to the grid itself. It affects and deteriorates the power supply quality of the power grid or local power grid, causing mains voltage waveform distortion or frequency drift. In addition, unexpected natural and man-made accidents, such as excessive load voltage, earthquakes, lightning strikes, power transmission and transformation system interruptions or short circuits, will endanger the normal supply of power and thus affect the normal operation of the load. In response to this situation, large-scale energy storage systems are currently being implemented to store excess electricity generated from renewable energy sources for use when power generation is low. In addition to data centers and UPS power systems, Shangyu CPSY® power energy solutions also include emergency power supplies, electric vehicle charging piles and voltage regulators.

2. Electric energy solutions-----electric vehicle charging piles

As my country's economic and social development level continues to improve, car ownership continues to rise. Vigorous development of electric vehicles can speed up fuel substitution and reduce vehicle exhaust emissions. It is of great significance to ensuring energy security, promoting energy conservation and emission reduction, preventing and controlling air pollution, and promoting my country's transformation from an automobile country to an automobile power.

However, the accelerated development of the new energy vehicle industry has exposed the bottleneck of the limited number of charging piles. At present, my country's industrial policy for the development of new energy vehicles, mainly pure electric vehicles, is becoming increasingly clear. According to the national plan, charging piles and electric vehicles will be popularized at a ratio of 1:1, which means that charging piles will inevitably usher in a construction peak in the future. With the deployment and implementation of new energy strategies, the number of electric vehicles continues to rise. The supporting electric vehicle charging and swapping facilities have taken the lead in construction, and will gradually form an electric vehicle charging and swapping system that combines charging piles, charging stations, battery swapping stations, and other facilities.

Charging piles generally provide two charging methods: AC slow charging and DC fast charging.

People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging methods, charging time, cost data printing and other operations. The charging pile display can display the charging amount, cost, charging time, etc. data. AC charging piles have low power and slow charging, and are suitable for home use; DC charging piles/machine have high power and fast charging, and are mostly used in public venues.

DC charging pile:

The AC smart energy meter performs power measurement. The AC contactor controls the on and off of the main circuit, and finally outputs to the charger. Interface connector for charging electric vehicles.

AC charging pile: The input circuit uses a small short circuit, a surge protector, and a small leakage short circuit to provide overload, short circuit, lightning protection, and leakage protection respectively. The AC smart energy meter performs power measurement, and the AC contactor controls the on and off of the main circuit. Finally, it is output to the charging interface connector to charge the electric vehicle.

Charging infrastructure mainly includes various centralized charging and swapping stations and decentralized charging piles. Due to the scattered locations and large number of charging facilities, in order to ensure user experience and operational efficiency, services such as charging navigation, status inquiry, charging reservation, and fee settlement must be provided. To provide these services, these charging facilities must be networked and connected. Build a charging intelligent service platform. The specific requirements for charging pile (station) networking are as follows:

3. Power energy solutions-----voltage regulator

Unstable voltage can cause fatal injuries or malfunctions to equipment, affect production, and cause multiple losses such as delivery delays and unstable quality. At the same time, it accelerates the aging of the equipment, affects the service life and even burns the accessories, causing the owners to face the trouble of needing repairs or updating the equipment in a short period of time, which wastes resources; in serious cases, safety accidents may even occur, causing immeasurable losses.

Therefore, the use of voltage stabilizers and UPS power systems is essential for electrical equipment, especially high-tech and precision equipment with strict voltage requirements.

The voltage regulating regulator is based on our company's intelligent CNC compensated AC voltage regulator. It is tailor-made for users in this industry who need multi-level voltage regulation for refrigeration unit testing or large laboratory users and special needs for electricity safety. A new generation of personalized intelligent fast energy-saving regulated power supply. The voltage regulating regulator adopts microcontroller intelligent control and is equipped with a multi-language LCD display, which highlights the safety, stability, energy saving and human-machine interface of this equipment.

There are three basic types of voltage regulators:

Buck Regulator — A voltage regulator with an output voltage lower than the input voltage

Boost regulator — A voltage regulator with an output voltage higher than the input voltage

Buck-boost regulator—can provide an output voltage higher, lower, or the same as the input voltage

The voltage regulator mainly regulates voltage into single-phase (D) and three-phase (S).

Voltage regulator symbol Three-phase compensated power voltage stabilizer.

The price of a voltage regulator with an additional surge suppressor and filter is 1.3 times that of an SBW voltage regulator.

The size of the voltage regulator is configured based on 2-3 times the power of the complete machine.

The voltage regulator relies on the beating of the relay to stabilize the voltage. When the grid voltage fluctuates slightly, or other electrical appliances are turned on or off within a certain range, the automatic correction circuit of the power voltage regulator will be activated, causing the relay to jump frequently. The biggest function of the voltage stabilizer is that it can control the output voltage of electrical appliances with large current fluctuations within a certain range to ensure the smoothness of the circuit and the normal use of the electrical appliances. Due to the instability of voltage, it can cause fatal injuries or malfunctions to the equipment, affect its use, and cause unstable quality. Therefore, a voltage regulator must be used.

SVC/TNS/TND series single and three-phase high-precision fully automatic AC voltage stabilizers are composed of contact auto-voltage regulators, servo motors, automatic control circuits, etc. When the grid voltage is unstable or the load changes, it automatically samples The control circuit sends a signal to drive the servo motor and adjust the position of the carbon brush of the autovoltage regulator so that the output voltage is adjusted to the rated value and reaches a stable state. SVC/TNS/TND series high-precision AC voltage regulator series voltage regulators have mains power pass-through function. It has the advantages of many varieties, complete specifications, and beautiful appearance. It has the advantages of non-distorted waveform, high efficiency, reliable performance and long-term operation. It is equipped with short delay, overvoltage and other protection functions. Long delay and undervoltage protection functions can be added according to user needs. The product can be widely used in any place where electricity is used. It is an ideal voltage-stabilized power supply to ensure the normal operation of your electrical equipment. Mainly used in office equipment, test equipment, medical equipment, industrial automation equipment, household appliances, lighting systems, communication systems, etc.

SBW series three-phase fully automatic high-power compensated split-type AC stabilized power supply is a new generation of energy-saving AC stabilized power supply designed and produced by our company with reference to AC voltage stabilization technology and according to my country's actual electricity consumption conditions. It is targeted at users' on-site power supply networks. Three-phase unbalanced voltage fluctuations or load unbalanced changes can automatically adjust and maintain stable output balance when voltage fluctuations occur.

Protection functions such as reverse phase protection and mechanical fault protection.

SBW and DBW series fully automatic high-power compensated AC stabilized power supplies (hereinafter referred to as voltage stabilizers) are a power supply product independently developed and designed by our company by introducing advanced foreign technology for this product and combining it with my country's national conditions. When the external power supply network voltage fluctuates or load changes cause voltage fluctuations, it can automatically maintain the stability of the output voltage. Compared with other types of voltage stabilizers, this series of products has large capacity, high efficiency, no waveform distortion, stable voltage, and is widely used in loads. , can withstand instantaneous overload, can operate continuously for a long time, implements unattended operation, can switch between manual control, automatic control, mains power, and voltage stabilization at will, and is equipped with automatic protection devices for overvoltage, undervoltage, overcurrent, delay, mechanical failure, and volume Small, light weight, easy to use and install, and reliable in operation. It can be widely used in large electromechanical equipment, metal processing equipment, production lines, construction engineering equipment, elevators, medical equipment, program-controlled computer rooms, CNC machine tools, printing equipment and textile equipment in the fields of industry, agriculture, transportation, postal and telecommunications defense, railways, scientific research and culture, etc. , air conditioners, radio and television, and household appliances, lighting and other places that require voltage stabilization.

Household voltage stabilizers are composed of voltage regulating circuits, control circuits, and servo motors. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate, causing the position of the carbon brush of the voltage regulator to change. , by automatically adjusting the coil turns ratio to maintain the stability of the output voltage. Voltage stabilizers with larger capacities also work on the principle of voltage compensation.

Voltage regulators serve two functions: converting an input voltage into different output voltage levels, and voltage stabilization (maintaining a constant output voltage under changing load conditions). DC-DC regulators are key components of any power supply system, so choosing the right regulator is crucial if you are to develop the most suitable solution.

Other features

Parallel function: If the voltage regulator can be connected in parallel, it can provide greater output current. Not all regulators can parallelize their outputs, as for many topologies this will introduce instability.

Constant current output: In battery applications, a constant voltage needs to be provided to the load, but constant current is required for charging. Some voltage regulators provide outputs that can be configured for constant current and constant voltage, making them ideal for these systems.

Soft Start: The ability to slowly increase voltage helps ensure power system stability even when large amounts of capacitance are connected to the regulator output.

Overvoltage Protection: Regulators are provided with protection to ensure that they do not deliver more than the defined output voltage, ensuring that the load is not damaged even in the event of a fault. Other protection circuits may disable the regulator if the input voltage is out of range.

Transient response: Some loads rapidly change the current they require. The fast transient response ensures that the regulator can provide the required power without the need for large output capacitors to store energy.

Voltage regulator The voltage regulator should be used indoors. The normal usage conditions are:

1. Ambient temperature: -10℃—+40℃

2. Altitude: <1000M

3. Relative humidity: 20﹪-90%

4. There are no gases, vapors, chemical deposits, dust, dirt and other explosive and corrosive media that seriously affect the insulation of the voltage regulator.

5. There is no serious vibration or bumps in the installation site.

Voltage stabilizers can be widely used in: electronic computers, precision machine tools, computed tomography (CT), precision instruments, test equipment, etc. in industrial and mining enterprises, oil fields, railways, construction sites, schools, hospitals, postal and telecommunications, hotels, scientific research and other departments. Places such as elevator lighting, imported equipment and production lines that require stable voltage from the power supply. It is also suitable for users at the end of the low-voltage distribution network where the power supply voltage is too low or too high, with large fluctuations, and for electrical equipment with large load changes. It is especially suitable for all voltage-stabilized power consumption places that require high power grid waveforms. The high-power compensated power voltage stabilizer can be connected to thermal power, hydraulic power, and small generators.

AC stabilized power supplies are widely used in the voltage stabilization and protection of modern high-tech products such as computers and peripheral devices, medical electronic instruments, communication and broadcast equipment, industrial electronic equipment, and automatic production lines. DC stabilized power supplies are widely used in DC power supply for national defense, scientific research, colleges and universities, laboratories, industrial and mining enterprises, electrolysis, electroplating, charging equipment, etc.

Daily precautions

1. Avoid violent vibration, prevent the inflow of corrosive gases and liquids, prevent it from being irrigated and place it in a ventilated and dry place. Do not cover it with fabric to hinder ventilation and heat dissipation.

2. Please use a three-prong (grounded) socket, and the grounding screw on the machine must be properly grounded. Otherwise, the case will be charged with a test pen. This is caused by distributed capacitance induced electricity, which is a normal phenomenon. You can pass the grounding wire eliminate. If the casing is seriously leaking and the insulation resistance is less than 2MΩ, it may be that the insulation layer has been dampened or the circuit and the casing are short-circuited. The cause should be identified and the fault eliminated before use.

3. The 0.5-1.5KVA low-power voltage stabilizer uses a fuse for over-current and short-circuit protection. The 2-40KVA voltage stabilizer uses a DZ47 circuit breaker for over-current and short-circuit protection. If the fuse often blows or the circuit breaker trips frequently, Check whether the power consumption is excessive.

4. When the output voltage exceeds the protection value (the phase voltage protection value is adjusted to 250V±5V when leaving the factory), the regulated power supply automatically protects and cuts off the output voltage of the regulated power supply. At the same time, the overvoltage indicator light turns on. The user should immediately shut down the power supply and check the grid voltage or Voltage stabilization. If the voltage regulator automatically cuts off power (with input but no output), check whether the mains voltage is higher than 28OV. If it is lower than 280V, check whether the voltage regulator is faulty. Wait until the cause is found out before using.

5. If the output voltage of the voltage regulator deviates greatly from 220V, please adjust the potentiometer on the control board until the output voltage is normal (if the input voltage does not reach the stable voltage range, it cannot be adjusted).

6. When the mains voltage is often at the lower limit (<150V) or upper limit (>260V) of the voltage regulator input voltage, the limit microswitch is often touched and control failure is prone to occur. At this time, the voltage regulator cannot adjust the voltage or can only adjust it higher (or only lower). You should first check whether the micro switch is damaged.

7. Please keep the inside of the machine clean. Dust will hinder the rotation of the gears and affect the accuracy of the output voltage. Please clean and maintain the coil contact surface clean in time. When the carbon brush wear is serious, the pressure should be adjusted to avoid sparking at the contact surface between the carbon brush and the coil. Carbon brushes should be replaced when their length is less than 2mm. When the coil plane flashover is blackened, it should be polished with fine sandpaper.

⒏The input end of the three-phase voltage stabilizer must be connected to the neutral line (neutral line), otherwise the voltage stabilizer cannot work under normal load and will damage the voltage stabilizer and electrical equipment. Never use a ground wire instead of a neutral wire (but the neutral wires can be connected in parallel), and the neutral wire must not be connected to a fuse.

9. When the output voltage of the voltage regulator is lower than the rated voltage (220V or three-phase 380V), check whether the input voltage is too low. When the rated voltage is reached at no load but the output is lower than the rated voltage when loaded, this is because the input line carrying area is too small, or the load end exceeds the rated capacity range of the voltage regulator, and the line voltage drop is too large when loaded. The input voltage is lower than The lower limit of the regulator's adjustment range. At this time, the input wire should be replaced with a thicker one or the product capacity should be increased.

10. When a single load has a large power (such as air conditioner, etc.), and the input line is long and the load area is insufficient, the voltage will be seriously reduced when the load is working, and it may be difficult to start the load; when the load is working and it is temporarily shut down, it is easy to occur If the output instantaneously overvoltages and cuts off power, it is not a voltage regulator failure. The input line should be improved (the line should be thickened and the length of the input line should be shortened as much as possible to reduce the voltage drop in the line).

11. When the output voltage of the voltage regulator seriously deviates from 220V, you should check whether ① the input voltage is within the stable voltage range; ② whether the motor gear is seriously worn and whether the rotation is flexible; ③ whether the limit switch is damaged: ④ whether the coil plane is smooth; ⑤ Is the control board damaged?

security matters

⒈When the regulated power supply is powered on, please do not disassemble the regulated power supply or pull out the input and output connections of the regulated power supply at will to prevent electric shock or other electrical safety accidents.

⒉The input and output connections of the voltage-stabilized power supply must be arranged properly to prevent them from being worn out due to trampling and causing leakage accidents.

⒊The regulated power supply must be reliably grounded. The user is responsible for any electric shock or personal injury caused by operation without a ground wire.

⒋The ground wire of the regulated power supply cannot be connected to heating pipes, water supply pipes, gas pipes and other public facilities to avoid infringing the rights of third parties or causing harm.

⒌The input and output connections of the regulated power supply should be checked regularly to avoid loosening or falling off, which will affect the normal use of the regulated power supply and the safety of electricity.

⒍The connection line of the voltage regulator must be selected to meet the specified connection line that can carry sufficient current capacity.

⒎. The voltage stabilizer should be handled with care and avoid severe vibration during operation;

⒏. Ensure that the carbon brush spring of the voltage regulator has sufficient pressure to prevent the contact surface between the carbon brush and the coil from sparking;

⒐. Non-professionals are not allowed to disassemble or repair the regulated power supply.
