Abstract

The invention discloses an on-site automatic detection device of a gas insulated switchgear (GIS), solving the technical problem that the current GIS can not undergo online live automatic detection. The device comprises a GIS (17), a movable telescopic track frame (4), a detection dolly (2) and a portable ultrasonic phased array scan imaging detection system. A telescopic track (1) and the detection dolly (2) are arranged on the telescopic track frame (4). A vertical bar (7) in the vertical direction of a drive motor (3) is arranged on the detection dolly (2). A sliding block (9) is movably arranged on the vertical bar (7) and is provided with a transverse bar (12) in the horizontal direction. A probe (13) is movably arranged on the transverse bar (12) and is connected with the portable ultrasonic phased array scan imaging detection system fixedly arranged in an electric cabinet (16). The device can diagnose the hidden defects wholly in advance.

Description

technical field [0001] The invention relates to a device for on-site automatic detection of gas insulated fully enclosed combined electrical appliances (Gas Insulated Switchgear, abbreviated as GIS). Background technique [0002] Gas Insulated Switchgear (GIS for short) is an advanced high-voltage electrical distribution device, and now generally uses SF 6 As an insulation and fire extinguishing medium, it has excellent electrical performance, and has the advantages of small footprint, all closed components, no environmental interference, high reliability, convenient operation, and less maintenance workload. It is widely used in substations and power grids. , electrified railway and other fields. With the increase of the operating life of the equipment, under the action of switch vibration and electric power, the movement of foreign matter and debris or the aging of insulation, etc., a partial discharge phenomenon occurs inside the equipment, which eventually develops into ...
