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.
