An integrated temperature measuring device for main transformer accessories, belonging to the field of transmission facility temperature measuring devices, comprises a pedestal, a transverse slide carriage moving left and right, a vertical slide carriage moving front and back, an outer rail, an inner rail, and a slide carriage. The rear end of the top surface f the vertical slide carriage is provided with a column. The column is provided with a third motor, and the third motor fits a leading screw slide block mechanism through the outer rail. The outer rail is equipped with an arc inner wall having inner teeth. The inner rail is equipped with outer teeth. The outer rail is fixedly connected to the inner rail. A driving motor for installation of a planetary gear is disposed below the slide carriage. The planetary gear engages with the outer rail and the inner rail. An installation stand equipped with an infrared imaging instrument is arranged on the top surface of the slide carriage. Motors and the infrared imaging instrument are connected to a central control chamber via a microprocessor. Through a computer control technology, temperature measurement points are measured at a fixed position and time by controlling the motors to adjust the left, right, front, back, up and down positions of the infrared imaging instrument, and operators do not need to arrive at a site and hold the infrared imaging instrument to record temperature measurements. Therefore, the temperature measuring efficiency is increased, and the labor intensity of operators is effectively reduced.
