Abstract
The invention relates to a high-voltage isolating switch. The high-voltage isolating switch is the important switching device of power station and transformer substation electrical systems, and needs to be used in cooperation with a high-voltage circuit breaker. According to the main function of the high-voltage isolating switch, the safety of a high-voltage electric appliance and device in the detection working process is ensured, the function of isolating voltages is achieved, the switch cannot be used for cutting off or inputting load currents or cutting off short-circuit currents, ablation occurs to an existing high-voltage isolating switch in the turning-on and turning-off process due to generated electric arcs, and the conductivity in the turning-off process is influenced. The high-voltage isolating switch comprises a framework (6), a stationary contact component is arranged on the front frame of the framework (6), a movable contact component is arranged on the rear frame of the framework (6), and a rotating shaft (7) is arranged on the left frame of the framework (6). The high-voltage isolating switch is used for isolating the high voltages of a power station.
