Problems solved by technology

[0003] The invention provides a large-current moving contact structure, which has the advantages of uniform force, stable use and increased conductive area, so as to solve the problem that the traditional moving contact is only a single part pressed by a copper plate, and it is unavoidable to suffer damage during use. Due to uncertain factors such as uneven force, when the conductive contact point of the moving contact clamps the conductive stud, because the two points cannot be guaranteed to be completely equal in height, there will be only one set of effective contact problems.

Abstract

The invention discloses a heavy-current moving contact structure, and relates to the technical field of electric power. The heavy-current moving contact structure comprises two first moving contact connecting plates, two second moving contact connecting plates, first connecting sheets and second connecting sheets, and the opposite surfaces of the two first moving contact connecting plates are fixedly provided with the first connecting sheets and the second connecting sheets, and the opposite surfaces of the two second moving contact connecting plates are fixedly connected with the opposite surfaces of the two first connecting sheets and the two second connecting sheets respectively. Conductive contact plates are formed by bending the second connecting sheets and are matched with third conductive contact points, so that an effective conductive contact point is additionally arranged at the back ends of the first moving contact connecting plates and the second moving contact connecting plates, and meanwhile, second conductive contact points are additionally arranged at the front ends of the first moving contact connecting plates and the second moving contact connecting plates, therefore, the overall conductive sectional area is increased, and larger load current can be borne.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a large-current moving contact structure. Background technique [0002] With the vigorous development of my country's electric power industry, the current load of the on-load tap-changer used by the majority of customers is gradually increasing, and the moving contact part of the existing on-load tap-changer is gradually unable to withstand the increasing current. The traditional moving contact is only a single part pressed by a copper plate, and uncertain factors such as uneven force will inevitably appear during use, so that when the conductive contact point of the moving contact clamps the conductive stud, it cannot be guaranteed that the two points are completely connected. equal height, there will be only one set of valid contacts. Contents of the invention [0003] The invention provides a large-current moving contact structure, which has the advantages of uniform f...
