Abstract

The invention discloses a method and device for detecting the internal smoothness of a GIS equipment air chamber. According to the device, ultraviolet light is employed for detecting the internal smoothness of the GIS equipment air chamber. The device comprises a connection module, an adjustment module, a light source module, an image capture module, an image analysis module, a storage module, anda diagnosis module, wherein the connection module is connected with the light source module and the image capture module, the light source module is connected with the adjustment module, the image capture module is connected with the image analysis module, the image analysis module is connected with the storage module, the storage module is connected with the diagnosis module, and the image capture module is used for receiving fluorescence intensity information of dirt. According to the method and device of the embodiment of the invention, the internal smoothness of GIS equipment can be quickly, directly and accurately detected in real time by utilizing the ultraviolet light, and early warning is truly realized by subsequently judging whether internal dirt reaches a threshold value causing discharge or not.

Description

technical field [0001] The invention relates to the technical field of electric power detection, in particular to a method and a detection device for detecting the smoothness inside a gas chamber of a GIS equipment. Background technique [0002] In recent years, gas-insulated metal-enclosed switchgear (GIS) has a small footprint, is less affected by climatic conditions, has a long service life, requires less maintenance work, has a compact structure, is easy to install, and is suitable for areas with complex terrain and narrow terrain. Features, widely used in power industry. However, as the number of GIS substations continues to increase, GIS equipment failures are also increasing. Analysis of the main reason for the failure is that the GIS equipment will inevitably generate suspended particles inside the equipment during the process of production, assembly, transportation, etc., and the inner wall and insulator surface will be dirty, which will drastically reduce the SF ...
