A high-voltage stationary contact with a grounding blade contact.

Abstract

This utility model discloses a high-voltage stationary contact with a grounding knife contact, including a wall bushing that passes through the middle of a contact mounting plate; a conductive rod is installed in the middle of the wall bushing, and an installation slot is opened at the front end of the wall bushing, with a perforated contact snapped onto the front end of the conductive rod; a strip-shaped slot is opened below the installation slot, and the front part of the conductive rod is connected to a grounding knife contact copper busbar via a contact connecting rod; a contact copper block is installed at the rear end of the wall bushing, and the rear end of the conductive rod passes through the wall bushing and is tightly connected to the contact copper block; a stud is fixedly connected to the rear side of the contact copper block, and a pressure plate is movably sleeved on the outside of the stud; a clamping nut is provided on the rear side of the pressure plate, and the clamping nut is connected to the stud via threads. This utility model overcomes the shortcomings of the prior art by combining the front end of the conductive rod with the grounding knife contact copper busbar, thus integrating the outgoing line terminal stationary contact and the grounding knife contact into one, thereby significantly reducing the space required for grounding knife installation and effectively reducing costs.
