Basic Overvie
Capacitor compensation cabinet is a device used to improve the power factor of power systems. It injects reactive current into the grid through parallel capacitors to offset the reactive power generated by inductive loads, thereby improving the power factor of the system. This type of equipment plays an important role in the power system, effectively improving power quality and supply efficiency.
The main functions of a capacitor compensation panel include improving power factor, reducing line loss, minimizing voltage fluctuations and harmonic disturbances, and extending equipment lifespan. It is widely used in industrial electricity, commercial buildings, power plants, railway systems, and other fields, especially in large industrial sites and power systems where the effect is particularly significant. By using capacitor compensation cabinets, not only can inductive loads be balanced, but energy can also be saved and electricity costs can be reduced, which is of great significance for the stable operation of the power system.
Advantages And Characteristics
- Improving power factor: By connecting capacitors in parallel, capacitive reactive power is provided to compensate for the reactive power required by inductive loads, reducing the transmission of reactive current in the power grid and thus improving the power factor of the entire power system.
- Improving voltage quality: stabilizing grid voltage, reducing voltage fluctuations and harmonic disturbances, especially in large industrial distribution equipment, can prevent voltage fluctuations from affecting production equipment.
- Reducing line losses: Increasing the power factor helps to reduce the losses incurred by distribution equipment when current passes through transmission lines, thereby reducing overall energy consumption and operating costs.
- Energy conservation: Effectively utilizing electrical energy, reducing ineffective power consumption, and achieving the effect of energy conservation and emission reduction.
- Extend equipment lifespan: Reduce the damage of harmonics to electrical equipment and extend the Service life of distribution equipment.
- Safe and reliable: The capacitor control cabinet has complete protection functions, such as overcurrent, undervoltage, short circuit, etc., to ensure the safe operation of the equipment.
Product Details
Capacitor compensation cabinet is an indispensable equipment in the power system. It mainly consists of capacitors, reactors, controllers and other components, and monitors the power factor of the power grid in real time through an intelligent controller. When a low power factor is detected, the corresponding number of capacitors will be automatically activated..
These invested capacitors can provide capacitive reactive power to the power grid, offsetting the inductive reactive power generated by inductive loads, thereby improving power factor, reducing line losses, making power transmission more efficient, ensuring stable operation of various electrical equipment, and playing an important role in industrial production, commercial electricity, and residential power supply scenarios..

Application areas
- Industrial capacitor compensation cabinet: In mechanical processing factories, the widely used AC asynchronous motors and other equipment are inductive loads, which can lead to a decrease in power factor. The capacitor compensation cabinet provides capacitive reactive power through parallel capacitors to compensate for the reactive power required by these inductive loads, thereby improving the system power factor, reducing the transmission of reactive current on transmission lines, lowering line losses, and improving energy utilization efficiency.
- Metallurgical industry capacitor compensation cabinet: In the production process of metallurgical enterprises, such as steelmaking, steel rolling, etc., there are a large number of electric furnaces, motors and other equipment operating, which have high power and are mostly inductive loads. The capacitor compensation cabinet can effectively compensate for reactive power, improve the power factor of the power grid, stabilize voltage, reduce the impact of voltage fluctuations on production equipment, and reduce the electricity cost of enterprises.
- Chemical industry capacitor compensation cabinet: Many equipment in chemical production, such as compressors, pumps, fans, etc., are inductive loads. Capacitor compensation cabinet can improve the power factor of the power grid in chemical enterprises, reduce line losses, improve the efficiency of electrical equipment use, and also help reduce the interference of harmonics on other equipment and control systems, ensuring the safe and stable operation of chemical production.
- Power system capacitor compensation cabinet: In various types of power plants such as thermal power plants, hydropower plants, and wind power plants, the electrical energy generated by the generator needs to be transmitted to the power grid through equipment such as step-up transformers. The capacitor compensation cabinet can perform reactive power compensation on the excitation system of the generator, improve the power factor of the generator, reduce the reactive power output of the generator, thereby increasing the active power output of the generator and improving the power generation efficiency.
