Abstract

The invention discloses a grounding switch. The grounding switch comprises a housing, a grounding body, a static contact and an end cover, wherein the grounding body is arranged in the housing; the static contact is arranged on the grounding body; the static contact is electrically connected with the grounding body; the end cover is arranged on the housing and fixedly connected with the housing; a dynamic contact is arranged in the housing; an optical position indicator and a sliding block are arranged on the dynamic contact; a crank and a guide column are arranged on one side of the sliding block; the crank is hinged to the sliding block; the sliding block is in sliding connection with the guide column; a control shaft is arranged on the crank and is in drive connection with the crank; a vibration absorber and a sliding sleeve are arranged at the bottom of the dynamic contact; and the sliding sleeve is in sliding connection with the dynamic contact. The grounding switch is accurate to control and stable and reliable in action, has a vibration reduction function and is long in service life.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a grounding switch. Background technique [0002] The grounding switch is a mechanical switch used for the grounding part of the circuit. It can carry the current under abnormal conditions (such as short-circuit current) for a certain period of time, but it is not required to carry the current under normal circuit conditions. [0003] Grounding refers to the neutral point of the power system and electrical devices, the exposed conductive parts of electrical equipment and the conductive parts outside the device are connected to the earth through conductors, and can be divided into working grounding, lightning protection grounding and protective grounding. [0004] The working grounding is set according to the operation needs of the power system (such as the neutral point grounding), so under normal circumstances, there will be current flowing through the grounding elect...
