A grounding switch device

Abstract

The invention relates to a grounding switch device which comprises a first shell, a second shell, a driving device, a second conductor, a third conductor, a fourth conductor and a first conductor, wherein the first shell and the second shell are connected into a whole through an insulating plate, the driving device and the second conductor are arranged in the first shell, the third conductor and the fourth conductor are arranged in the second shell, and the first conductor is arranged between the first shell and the insulating plate; the inner part of the first conductor is electrically connected with the second conductor through a first spring contact finger, and the outer part of the first conductor is electrically connected with the second shell through a connecting line; one end of the third conductor is fixed in the second shell through an insulating piece, and the other end of the third conductor is electrically connected with the fourth conductor through a second spring contact finger; a fixed contact which is matched with the inserting end of the second conductor is arranged on one side of the third conductor; the driving device comprises a first crank arm, a second crank arm and a rotating shaft, wherein the first crank arm and the second crank arm are fixedly connected in sequence, the rotating shaft passes through the first shell, the first crank arm is arranged in the first shell, the free end of the first crank arm is connected with the driving end of the second conductor, the second crank arm is arranged outside the first shell, and the free end of the second crank arm is connected with the output end of a driving mechanism.

Description

Technical field [0001] The invention relates to the field of high-voltage power switch equipment, in particular to a grounding switch device. Background technique [0002] In the current field of high-voltage circuit breakers, combined electrical products need to have a grounding switch device. In order to ensure the safety of the maintenance personnel during product maintenance, the internal conductor needs to be reliably grounded and can be grounded quickly. However, the existing structure is more complicated. Point contact adopts plum blossom contact, which is large in size, low in reliability and small in scope of application. Summary of the invention [0003] In view of the problems in the prior art, the present invention provides a simple assembly, reliable performance, and low cost, which can satisfy a reliable grounding switch device. [0004] A grounding switch device includes a first body and a second body that are connected as a whole through an insulating plate, a trans...
