High-voltage isolation switch grounding device

Abstract

The invention discloses a high-voltage isolation switch grounding device. The device comprises an isolation switch base, wherein the top of the isolation switch base is provided with three porcelain columns at equal intervals from left to right. Bearing sheets are arranged at the tops of the three knob insulators; a first circuit board, a second circuit board and a third circuit board are respectively arranged at the tops of the three bearing sheets; connecting plates are connected to the front surfaces of the first circuit board, the second circuit board and the third circuit board; the bottoms of the three connecting plates are connected to the top of the isolation switch base, sleeves penetrate through the middles of the surfaces of the three connecting plates, grounding wires are arranged in the sleeves, the right side face of the first circuit board is connected with a first supporting block, the tail end of the first supporting block is connected with a first static contact, andthe right side face of the second circuit board is connected with a second supporting block. The high-voltage isolation switch grounding device replaces a specific high-voltage isolation switch grounding device to be applied to a specific high-voltage area, great convenience is brought to maintainers, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a grounding device for a high-voltage isolating switch. Background technique [0002] Grounding device is also called grounding integration device: a device that forms an electrical connection between electrical equipment or other objects and the ground. (Building Electrical Construction Technology). The grounding device consists of grounding electrodes (plates), grounding busbars (indoors, outdoors), grounding downconductors (grounding jumpers), and frame grounding. It is used to achieve the purpose of connecting the electrical system to the earth. The metal object that is in direct contact with the earth to realize the electrical connection is the ground electrode. It can be an artificial grounding pole or a natural grounding pole. The grounding electrode can be given some electrical function, such as system grounding, protective grounding or signal grounding. The ...

Problems solved by technology

However, due to the different voltage amplitudes of high-voltage power distribution devices in different regions or places, ordinary high-voltage isolating switch grounding devices cannot be applied to various high voltages, and specific high-voltage isolating switch grounding devices are required to be used in specific high-voltage area, which brings great inconvenience to maintenance personnel and makes it difficult to improve work efficiency
