The working principle of high voltage switchgear

According to certain wiring methods, the manufacturer assembles the switchgear, busbars, measuring instruments, protective appliances and auxiliary equipment of the same circuit in a closed metal cabinet, and supplies the user as a complete set. High-voltage switches are generally suitable for AC 50 Hz, 3-35 kV power systems, and are used for on-off, monitoring and protection of electrical energy reception and distribution.

What are the functions of the DC power cabinet?

DC power supply cabinet is a kind of DC power supply system. DC power supply cabinet is mainly used in hydraulic and thermal power plants, various substations and other users who use DC equipment. A power supply device that provides DC power for the opening and closing operations of a circuit breaker.

What are the advantages of power distribution cabinets?

First, traditional power distribution cabinets use pointer meters or digital display meters, which can only monitor the parameters of power distribution cabinets to meet basic needs. Intelligent power distribution cabinets use computer motherboards with high integration and high reliability. Various operating parameters of the monitoring system are monitored and displayed comprehensively through HMI, which reduces the space occupation of the power distribution cabinet and improves the volume ratio of the power distribution cabinet.

High and low voltage distribution cabinet

High and low voltage power distribution cabinets, as the name implies, are power distribution equipment used for power distribution, control, measurement and connection of cables in the power supply system. Generally, power supply bureaus and substations use high voltage switch cabinets, and then step down the low voltage side through transformers. Lead out to low-voltage power distribution cabinets, low-voltage power distribution cabinets, and then to power distribution boards, control boxes, and switch boxes, where some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protection devices Equipment assembled into a power distribution device that meets the design functional requirements.
