Reactive power compensation cabinet, also known as reactive power compensation cabinet, is a device used in power supply systems to improve the power factor of the power grid, reduce losses in power transformers and transmission lines, enhance power supply efficiency, and improve the power supply environment.
Main function:
Improve the power factor of the power grid and electrical equipment by providing necessary reactive power to compensate for the reactive power consumed during load operation.
Reduce the losses of power transformers and transmission lines, thereby improving the power supply efficiency and quality of the power grid.
Improve the power supply environment to ensure the stability and reliability of power supply.
Working principle:
The reactive power compensation cabinet exchanges energy between two types of loads through devices with capacitive power loads such as parallel capacitors and inductive power loads. In this way, the reactive power required by inductive loads can be compensated by the reactive power output by capacitive loads, thereby reducing reactive current and improving power factor.
Basic structure:
The reactive power compensation cabinet is usually composed of a cabinet body, a capacitor bank, a switching switch, a controller, and other parts. Among them, the capacitor bank is the core component used to provide reactive power; The switching switch is used to control the switching of capacitor banks; The controller is responsible for monitoring the power factor and reactive power of the power grid, and controlling the action of the switching switch as needed.
