High voltage switchgear refers to electrical products, high-voltage high-voltage disconnectors and grounding device power switches, high-voltage high-voltage load switches, high-voltage reclosers and sectionalizers, high-voltage practical operation organizations, high-voltage explosion-proof power distribution equipment and high-voltage switchgear, which are used for generating capacity, power transmission and distribution, power distribution equipment, power distribution stations and power consumption of the power supply system. High voltage switchgear High voltage is mainly used in power plants, power distribution stations, petrochemical, metallurgical industry cold rolling, light industry textile industry, factories and mining enterprises, residential quarters, multi-storey buildings and other different sites.
To ensure the normal operation, maintenance, safety of short circuit and overvoltage of high-voltage electrical components in high-voltage switchgear, high-voltage switchgear shall be selected according to the following standards:
(1) According to natural environment standards, including temperature, environmental humidity, altitude, seismic fortification intensity, etc;
(2) According to normal working conditions, including working voltage, current, frequency, mechanical equipment load, etc;
(3) According to short-circuit conditions, including withstand current in short term, maximum withstand current, rated short-circuit reclosing, overcurrent, etc;
(4) According to overvoltage tolerance, including insulation level;
(5) According to the different characteristics of various high-voltage household appliances, including the operating characteristics of the power switch, the maintenance characteristics of the fuse, the load and accuracy level of the transformer.
