Partial discharge detection device based on GIS withstand voltage flashover positioning system

Abstract

The invention relates to the technical field of withstand voltage partial discharge detection, in particular to a partial discharge detection device based on a GIS withstand voltage flashover positioning system. The device comprises a partial discharge equipment body, a detection mechanism, moving mechanisms, an adjusting mechanism, a control mechanism, a protection mechanism and a driving mechanism. The detection mechanism is installed at the top of a partial discharge equipment body. Therefore, the withstand voltage partial discharge of the GIS equipment can be detected and processed conveniently; meanwhile, two groups of moving mechanisms are mounted, so that the partial discharge equipment body can be moved conveniently and physical exhaustion of an operator is reduced; under rotationby the driving mechanism, the control mechanism drives and adjusts the adjusting mechanism; the partial discharge equipment body can be stably placed and conveniently moved; the height of the moving mechanism is changed through action adjustment of the adjusting mechanism, the partial discharge equipment body can be moved and placed; and meanwhile, internal parts of the moving mechanisms can be protected under the action of the protection mechanism.

Description

technical field [0001] The invention relates to the technical field of pressure-resistant partial discharge detection, in particular to a partial discharge detection device based on a GIS pressure-resistant flashover positioning system. Background technique [0002] The full name of GIS in Chinese is gas-insulated switchgear, which encapsulates all the primary equipment except the transformer in the tube, and the inside is filled with 0.4-0.7MPa SF6 gas as the insulating medium. Therefore, it occupies less space than ordinary open power stations. It is widely used in newly built, rebuilt or expanded substations due to its small area, long maintenance cycle, and low environmental impact. According to the regulations of GB50150, before the GIS is put into operation, the on-site handover test should be carried out. The most important one is the power frequency withstand voltage test. In order to facilitate the wiring during the test and save the test time, all intervals are oft...

Problems solved by technology

[0003] During the withstand voltage test, it is necessary to use a partial discharge device for detection, so as to obtain complete data and perform better withstand voltage detection on GIS. The existing Patent No.: 201822277254.4 A partial discharge detection device can efficiently detect partial discharge under pressure for equipment, but it is inconvenient to adjust the limit of the roller at the bottom when the device is in use, so that the equipment will produce Sliding or unstable phenomenon, causing casualties in severe cases
