What equipment is required for power compensation of low-voltage capacitor cabinets?

Low-voltage capacitor cabinets are often used for power compensation in power systems. The investment in capacitor cabinets can reduce reactive power losses, reduce grid load, and improve power supply quality. But if companies want to achieve effective power compensation in low-voltage capacitor cabinets, they need to equip some key equipment.
Low-voltage capacitor cabinet power compensation requires the following equipment:
1. Power capacitor bank: Power capacitor is a device used to compensate the reactive power in the power grid and improve the power factor. A capacitor bank generally consists of multiple capacitors connected in parallel and has an appropriate rated capacity.
2. Contactor: The contactor is used to control the switching state of the capacitor bank to automatically put in or remove the compensation capacitor according to the power demand.
3. Current transformer: Current transformer is used to monitor current changes in the power grid, provide feedback signals to the control system, and realize automatic control of the input and removal of compensation capacitors.
4. Controller: The controller is the core part of the compensation capacitor system. It is used to monitor the power factor and current changes of the power grid, and control the opening and closing of the contactor according to the set value to achieve automatic compensation.
5. Protection device: The protection device is used to monitor the working status of the capacitor bank, such as over-current, over-temperature and other abnormal conditions, and promptly cut off the power supply to the capacitor bank to avoid faults.
6. Power cable: Power cable is used to connect capacitor banks, contactors, transformers and other equipment to transmit electrical energy and signals.
To realize the effective operation of low-voltage capacitor cabinets, enterprises need to equip key equipment such as capacitor banks, power capacitors, contactors, protective devices, voltage transformers and current transformers. Through the cooperation of these devices, the power factor of the power system can be improved, the quality of power supply can be optimized, and the goals of energy conservation and emission reduction can be achieved.
