Basic introduction of 1. high voltage switch cabinet

High-voltage switchgear is a power distribution equipment used for power distribution, control, measurement and connection cables in the power supply system. Generally speaking, power supply bureaus and substations use high-voltage switch cabinets, and then lower the low-voltage side bow to the low-voltage distribution box through the transformer.

Low-voltage distribution box in a variety of power distribution boards, control cabinets, distribution boxes, the use of some switches, circuit breakers, fuses, buttons, display lights, meters, wires and other protection devices assembled to meet the design requirements of the functional power distribution equipment machine. Switchgear or high and low voltage electrical equipment.

2. the efficacy of each distribution box

High-voltage incoming cabinet, metering cabinet, high-voltage outgoing cabinet, low-voltage incoming cabinet, capacitance cabinet, low-voltage outgoing cabinet, these distribution boxes are the regular equipment of the power distribution room, whether high-voltage or low-voltage are combined according to certain functions.

(1) High-voltage incoming cabinet: This is a high-voltage cabinet that turns on the high-voltage incoming power supply. It's not really a line cabinet. The incoming line is generally not connected to this cabinet, but to the isolation cabinet, but there is a circuit breaker (vacuum) to turn on the incoming line power, so it is called the incoming line cabinet.

(2) Metering cabinet: Simply put, it is a cabinet used to install watt-hour meters and accurately measure how much electricity you use. Apart from the cabinet, this cabinet has no large components except PT and CT.
      
(3) High-voltage outgoing cabinet: Its function is to distribute and transport electric energy. He usually carries transformers or high-voltage electrical equipment (motors) and high-voltage compensation equipment

(4) Low-voltage incoming cabinet: generally a cabinet from the transformer, also called a low-level cabinet, used to control all the electrical equipment below. His main switch is usually a frame circuit breaker.

(5) Capacitor cabinet: its function is used to compensate for the quality of electricity and improve the power factor!

(6) Low-voltage outgoing cabinet: Its function is to distribute and transport electric energy. Different from high voltage, it basically enters the electrical equipment directly, and the switch generally adopts a plastic case circuit breaker.
