Abstract

The invention discloses an isolating switch, which comprises a base, a moving contact insulating support and a static contact insulating support respectively arranged on the base, a moving contact body installed on the moving contact insulating support, and a moving contact insulating support installed on the static contact insulating support. The static contact body, the outer side of the bottom end of the static contact body is provided with an elastic closing device for stably closing and opening the moving contact body and the static contact body, and the elastic closing device is fixedly connected to the base. For the switch, by setting an elastic closing device on the outside of the static contact body of the isolating switch, the elastic closing device can prevent the phenomenon of impact between the moving contact body and the static contact body due to excessive force when closing the switch. On the other hand, it can make stable contact between the moving contact body and the static contact body, and effectively improve the safety performance of the isolating switch.

Description

technical field [0001] The invention relates to the technical field of high-voltage switches, in particular to an isolation switch. Background technique [0002] The isolating switch is a switching device that is mainly used for "isolating the power supply, switching off operation, connecting and cutting off small current circuits" and without arc extinguishing function. Distance and obvious disconnection signs; when in the closed position, switchgear that can carry current under normal circuit conditions and current under abnormal conditions (such as short circuit) within a specified time, generally used as a high-voltage isolating switch, that is, the rated voltage is The isolation switch above 1kV has a relatively simple working principle and structure, but due to the large amount of use and high requirements for work reliability, it has a great impact on the design, establishment and safe operation of substations and power plants. The main feature is that it has no arc ...
