Abstract
The utility model relates to a novel ground switch gear which comprises a stander and a rotating shaft arranged on the stander, and is characterized by also comprising a three-phase moving contact and a three-phase fixed contact matched with the moving contact to work, and the three-phase moving contact is connected with a moving contact arm hinged on the rotating shaft by a rectangular confluence copper bar. The device not only has good contact performance, but also has simple structure and good use effect.
Description
Technical field
The utility model relates to a kind of novel grounded switching device.
Background technology
In the prior art, the confluence copper bar of earthed switch is processed with two sections copper tubes, is processed into fixed contact with independent T type copper bar, the fixed contact processed complex, and waste material, and the overlapped points in the loop is more.
Summary of the invention
The purpose of this utility model is to provide a kind of novel grounded switching device, and this installs, and not only contact performance is good, and simple in structure, and result of use is good.
For realizing goal of the invention, the utility model provides a kind of novel grounded switching device, comprise frame and the rotating shaft of being located on the frame, it is characterized in that: also comprise three-phase moving contact and with the three-phase fixed contact of three-phase moving contact cooperating, described three-phase moving contact is connected with acting arm on being articulated in rotating shaft through a rectangle confluence copper bar.
The beneficial effects of the utility model are that confluence copper bar is selected a rectangle row for use, and processing is simple, and is easy for installation.The fixed contact that utilizes branch row to make the ground cutter has reduced the overlapped points of material and element loop.And fixed contact upper end and current transformer overlap joint, lower end and moving contact overlap joint are compared faying surface of single-phase minimizing with existing main product.In addition, moving contact is designed to U-shaped and is connected with the rectangle confluence copper bar, has simplified manufacturing procedure greatly.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Embodiment
