Use of high and low voltage switchgear

Mar 09, 2021

High and low voltage switch cabinets are connected to high voltage equipment and low voltage equipment. Generally, the power supply bureau uses high voltage lines to connect to the ring network cabinet of the community, and then from the ring network cabinet to the transformer, and then to the low voltage cabinet after the transformer is reduced. The distribution boxes that use electricity are nothing more than switches and circuit breakers. High and low voltage switchgear, as the name implies, is equipment for connecting high voltage or low voltage cables. Generally, power supply bureaus and substations use high voltage cabinets, which are then stepped down by transformers to low voltage cabinets, and low voltage cabinets to various power distribution boxes. , There is nothing more than assembling some protection devices such as switch and circuit breaker into a whole electrical equipment. The high and low voltage switch cabinet is a kind of electrical equipment. The main control switch in the external cabinet, then enters the sub-control switch, and each branch is set according to its needs. Such as instrumentation, automatic control, motor magnetic switch, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, equipped with high-voltage busbars, such as power plants, etc. Load shedding.
