Insulating sleeve sealing detection device for gas insulated switchgear

Abstract

The invention belongs to the technical field of switch cabinet equipment, and particularly discloses an insulating sleeve sealing detection device for a gas insulated switchgear, the device comprises a box body, the box body is composed of four side plates, an upper bottom plate and a lower bottom plate, a pair of side plates of the box body are provided with a plurality of hexagonal through holes, the through holes are provided with mounting flanges, and the mounting flanges are connected with the peripheries of the through holes by welding studs. The insulating sleeve is mounted on the mounting flange and is fixed with the side plate of the box body, a window is arranged on the side plate on the other opposite side, the window is sealed by a mounting sealing plate with the same size as the window, and a barometer seat is welded on the window and is used for mounting a barometer. The insulating sleeve sealing detection device for the gas insulated switchgear can meet the requirement for gas tightness detection before the insulation sleeve of the gas-insulated switchgear is assembled, products of multiple specifications can be detected at the same time, the detection efficiency is high, and the requirement for reworking and repairing is reduced.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a sealing detection device for an insulating bushing used in an inflatable cabinet. Background technique [0002] The inflatable cabinet product is to seal the conductive part of the main circuit in the insulating gas, so the performance is not affected by the external environment. The equipment can operate safely for a long time in places with harsh environments. It also has a small footprint, less maintenance or even maintenance-free. The characteristics of convenient layout have already begun to be applied on a certain scale. An important factor affecting the product quality of the inflatable cabinet is air tightness, and the insulating sleeve is one of the key components, and its performance directly affects the quality of the product. At present, the insulating bushings for inflatable cabinets are outsourced. During the factory inspection process of outsourced manuf...
