Detection device and method for simulating different discharge faults in GIS

Abstract

The invention provides a detection device and a method for simulating different discharge faults in a GIS, and relates to the technical field of high-voltage switches. A window, a spectrum channel and an air inlet and outlet are formed in the side wall of a tank body of the device and are uniformly distributed around the side wall of the tank body at the horizontal position of an electrode, round holes are formed in the circle centers of upper and lower end cover plates of the tank body, and one end of a high-voltage guide rod 1 sequentially penetrates through the round hole of the upper end cover plate, an insulating column and a voltage equalizing cover and is connected with a test power supply, the other end is sequentially connected with a metal transition piece 1, an electrode and contact, a metal transition piece 2, and a high-voltage guide rod 2; the high-voltage guide rod 2 penetrates through a circular hole of the lower end cover plate to be grounded, four distance adjusting screw rods perpendicular to a base are evenly distributed on the edge of the base, one ends of the distance adjusting screw rods are fixedly connected with the base in a welded mode, connection with corresponding screw holes is realized through a positioning disc, the center of the base is provided with a round hole for passing through of a corrugated pipe; one end of an insulating pull rod is installed in a circular hole in the center of a fixing disc through a screw, and the other end of the insulating pull rod is connected with the high-voltage guide rod 2.

Description

technical field [0001] The invention relates to the technical field of high-voltage switches, in particular to a detection device and method for simulating different discharge faults inside a GIS. Background technique [0002] GIS (Gas Insulated Enclosed Combined Electrical Appliance) has the advantages of small footprint, reliable operation, long maintenance time, etc., so that GIS is more and more used. However, in the process of manufacturing, transportation and installation of GIS, due to the production process, mechanical vibration, installation negligence and lax maintenance, etc., it will inevitably cause different degrees of insulation defects inside the GIS, and eventually lead to different discharge faults inside the GIS. At present, the common method of GIS fault diagnosis and detection is gas detection method, which is very expensive based on GIS entities, and it is not realistic to explore the relationship between different discharge faults and decomposition pro...

However, in the process of GIS manufacturing, transportation and installation, due to the production process, mechanical vibration, installation negligence and lax maintenance, etc., it will inevitably cause different degrees of insulation defects inside the GIS, and eventually lead to different discharge faults inside the GIS.

At present, the common method of GIS fault diagnosis and detection is gas detection method, which is very expensive based on GIS entities, and it is not realistic to explore the relationship between different discharge faults and decomposition products through a large number of experiments, so some simple tanks are designed to simulate various It is necessary to analyze the discharge fault
