A grounding switch with grounding operating mechanism

Abstract

The invention discloses an earthing switch with an earthing operating mechanism, and solves the problems that earthing switches in existing bidirectional automatic switching looped network equipment are two independent earthing switches with earthing operating mechanisms, are not combined into a whole, exist in the form of disconnecting link sheet contact and are complex in processing and assembling, and probability of misoperation is increased relatively as the two earthing switches are not interlocked. The earthing switch comprises an earthing switch body and the earthing operating mechanism, and the earthing operating mechanism is connected with a spindle of the earthing switch body and used for driving the earthing switch body to be closed or opened; the earthing switch body comprises three switches in series connection, and the left closing switch in the earthing switch body and the right closing switch in the earthing switch body respectively share the same spindle. The earthing switch has the advantages that the earthing switch which is an integrated earthing switch is simple to process and simple and convenient to install, a function of interlocking between the mechanisms is realized, misoperation is avoided, and accordingly, the earthing switch is safer, more reliable, lower in cost, simpler and more convenient to install and the like than an existing earthing mechanism.

Description

technical field [0001] The invention relates to a grounding switch with a grounding operating mechanism, in particular to a grounding switch with a grounding operating mechanism used in bidirectional automatic switching ring network equipment. Background technique [0002] At present, the grounding switch in the existing two-way automatic switching ring network equipment is two independent grounding switches with a grounding operating mechanism, which are not integrated. The main reason is that there is a type of knife-brake contact, and the processing and assembly are complicated. There is no interlock between the two, so the chances of misoperation are relatively high. [0003] The grounding of the traditional grounding switch with a grounding operating mechanism, the blade contact surface will be uneven, or the angle will deviate, which will lead to poor contact and high resistance, resulting in a large amount of heat on the contact surface, which will cause safety proble...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: the grounding switch in the existing two-way automatic switching ring network equipment is two independent grounding switches with a grounding operation mechanism, which are not integrated into one body, and are mainly contacted by the knife blade. The type exists, the processing and assembly are complicated, and there is no interlock between the two, so the probability of misoperation is relatively increased
