Portable shielding top copper bar bus cutting machine

Abstract

The invention discloses a portable shielding top copper bar bus cutting machine which comprises a base. A support sliding bar is arranged at the upper part of the base; an electric motor is connected to the support sliding bar slidably; the bottom end of the electric motor is fixedly connected with an isolation drum in which a grinding wheel cutter is arranged; and the electric motor is in transmission connection with the grinding wheel cutter through a telescopic transmission component. The invention has simple structure and convenient use, no many persons are needed for careful cooperation and a cable caliber is not needed manipulating manually in the cutting process, thereby improving the working efficiency, saving the labor cost and the working time, shortening the replacing time of arelay protection device and improving the reliability of a mains supply; meanwhile, the cut surface of a bus is even, thereby avoiding the short circuit caused by the unevenness of the cut surface. In addition, operators do not need to directly use the cable caliber to cut the bus, thereby preventing the operators from electric shock.

Description

technical field [0001] The invention relates to substation relay protection reconstruction equipment. Background technique [0002] When the relay protection device of the power equipment in the substation exits, it is necessary to disconnect the special small busbars connected to each other on the top of the screen. The traditional method is to use large calipers to cut the busbars. This method is easy to cause a short circuit of the busbars, resulting in misoperation of the protection device. Or refuse to move, bringing great hidden dangers to the safe and stable operation of the power grid. With the rapid development of my country's power system, the comprehensive automation transformation of substations is being stepped up accordingly. However, when the old relay protection screen is withdrawn for relay protection transformation, it is necessary to cut off the live and exposed small busbars. The traditional general method is to use cable pliers to cut the small busbar ...

AI Technical Summary

Problems solved by technology

The cutting process requires the careful cooperation of many people. Although the staff is very serious, cautious, and careful, due to the small gap between the small busbars, the exposed electrification, and the small spaces between the small busbar bars and layers, the cutting process is time-consuming and laborious; The operation is prone to deviation, the cut section is very irregular, and it is easy to cause a short circuit of the small busbar; the operator is also in danger of electric shock; when the new screen is in place, there is a risk of short circuit and grounding caused by touching the live small busbars on both sides
