GIS positioning-based handheld partial discharge detection device

Abstract

The invention relates to the field of partial discharge detection devices, in particular to a GIS positioning-based handheld partial discharge detection device, which comprises a main body, a protection mechanism, a shielding mechanism, a pulling mechanism, a limiting mechanism and a charging mechanism, easily-damaged edges and corners of the main body can be protected through the arrangement of the protection mechanism, the designed convenient-to-hang part liberates the hands of a user, the user is prevented from holding the charging mechanism for a long time, the portability of the device is improved, and the exposed part of the charging mechanism can be shielded and the appearance of the main body can be beautified through the arrangement of the shielding mechanism. Through arrangement of the pulling mechanism, after limitation of the limiting mechanism on the shielding mechanism is removed, a sealing component in the shielding mechanism can be reset to an initial position, through arrangement of the limiting mechanism, the sealing component in the shielding mechanism can be conveniently limited in the main body, and through arrangement of the charging mechanism, electric quantity can be supplemented to the main body in time; and the hidden charging design improves the integration level and the aesthetic degree of the main body.

Description

technical field [0001] The invention relates to the field of partial discharge detection devices, in particular to a hand-held partial discharge detection device based on GIS positioning. 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 often tested at the same time according to the phase...

Problems solved by technology

[0003] In the withstand voltage test, it is necessary to detect through the partial discharge device, so as to obtain complete data, and perform better withstand voltage detection on GIS. In order to facilitate users to carry partial discharge equipment, a handheld partial discharge detection device was born. Traditional handheld partial discharge devices generally do not have a flat panel for...
