Abstract

The invention relates to a simulation device for poor contact of a GIS internal contact and an infrared calibration method. The simulation device comprises a shell, and a static conductor, a moving conductor, a non-standard plum blossom contact, an insulator and a contact insulating support which are arranged in the shell, wherein one end of the static conductor, the non-standard plum blossom contact and one end of the moving conductor are connected in sequence to form a conducting loop, the static conductor is fixedly connected with the non-standard plum blossom contact, the moving conductoris detachably connected with the non-standard plum blossom contact, the other end of the static conductor is connected with the shell through the insulator, the other end of the moving conductor is connected with the shell through the insulator, the contact insulating support is arranged on the non-standard plum blossom contact in a sleeving mode and connected with the shell, and the non-standardplum blossom contact is a plum blossom contact with a variable spring pitch diameter. Compared with the prior art, the simulation device replaces a GIS bus cylinder to carry out fault simulation and test, an infrared calibration experiment can be carried out, the accuracy of infrared detection is improved, and the purpose of conveniently detecting GIS faults is achieved.

Description

technical field [0001] The invention belongs to the technical field of GIS thermal fault simulation detection, and in particular relates to a simulation device and an infrared calibration method for poor contact of GIS internal contacts. Background technique [0002] At present, whether the gas-insulated metal-enclosed switchgear (abbreviation: GIS equipment, Gas Instulated Switchgear) can work normally is related to the safe and stable operation of the power system. With the increasing number of GIS equipment and the increasing operating life, various defects are gradually increasing. Heating defects are the main defect type of GIS faults, especially for contacts. GIS equipment is mostly high-voltage and high-current. Once a fault occurs, the temperature of the contacts will increase rapidly. In recent years, equipment failures caused by heat are not uncommon, and have caused many accidents such as equipment outages and even explosions. Therefore, it is of great significanc...
