[0002] High-voltage switchgear refers to the switchgear used for power generation, transmission, distribution, power conversion and consumption in the power system, and plays the role of switching, control or protection. High-voltage switchgear is divided into several categories according to the voltage level of 3.6kV ~ 550kV, including high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switchgear. In order to prevent the high-voltage switchgear from interfering with the passing staff in the factory, the high-voltage switchgear is generally placed in a relatively narrow space.
