The utility model provides a GIS equipment contact temperature monitoring test apparatus, which comprises a conductor, a conductor plugging contact seat, an experimental tank body, sleeve pipes, flanges and a movable support. The sleeve pipes include a first sleeve pipe and a second sleeve pipe. The conductor is inserted into the conductor plugging contact seat and placed inside the experimental tank body. The outer side tank wall of the experimental tank body is sequentially provided with the first sleeve pipe, the flanges and the second sleeve pipe from top to bottom. The movable support supports the apparatus through adjustable support bars. Flexible movement is achieved. The experimental tank body exerts currents through the sleeve pipes. By changing the resistance values of a moving contact resistor and a static contact resistor or adjusting the magnitude of an externally exerted current, the temperature of a detected part can be changed. Infrared temperature measurement and thermocouple temperature measurement can be then performed. The gas component and density inside the experimental tank body can be changed by means of an inflation joint. The influence of gas insulation mediums on infrared temperature measurement can be then determined. The apparatus has a simple structure and is easy to install.
