Problems solved by technology

[0003] Commonly used temperature measurement methods on high-voltage switchgear include ordinary temperature measurement, infrared temperature measurement, fiber Bragg grating temperature measurement and wireless temperature measurement. Since GIS is a fully enclosed device, its insulation requirements, sealing requirements and service life requirements, etc., make Ordinary temperature measurement method, fiber grating temperature measurement method and conventional wireless temperature measurement method cannot be applied to the online tem

Abstract

The invention provides a GIS equipment contact temperature monitoring test apparatus which comprises a conductor, a conductor plugging contact seat, a test tank, sleeves and flanges, wherein the sleeves includes a first sleeve and a second sleeve; the conductor is inserted into the conductor plugging contact seat and is placed in the test tank; and the first sleeve, the flanges and the second sleeve are sequentially mounted from top to bottom on an outer-side tank wall of the test tank. The test tank, through applying current via the sleeves and methods of changing the resistance of contact resistors of a moving contact and a fixed contact or a method of adjusting the magnitude of the externally applied current, changes the temperature of a tested part, and thus infrared temperature measurement and thermocouple temperature measurement are conducted, and gas components and concentration in the test tank are changed through a gas-charging connector, and the influence of the gas insulation medium on infrared temperature measurement is determined. The GIS equipment contact temperature monitoring apparatus is simple in structure and easy to install.

Description

technical field [0001] The invention belongs to the technical field of power transmission and transformation equipment, and in particular relates to a GIS equipment contact temperature monitoring test device. Background technique [0002] GIS equipment is more and more applied to the power system due to its many advantages such as less maintenance workload, small footprint, and high reliability. However, once a failure occurs, the maintenance cost is high and the cycle is long, which seriously affects the normal operation of the power grid. As an important means of power system fault diagnosis, monitoring is beneficial to discover the initial faults of GIS equipment, prevent accidents from expanding, and provide further guarantee for the normal operation of GIS equipment. Excessive GIS load current, loose connection parts, improper closing of the switch or wear of the contacts may cause the temperature rise of the conductive parts to be too high. Real-time monitoring of the ...
