Equipment for self-protection by using working temperature of transformer

The invention relates to the technical field of transformer self-protection, and further discloses equipment for self-protection by using the working temperature of a transformer. The equipment comprises a wall body, a sliding rail is fixedly connected to the surface of the wall body, a shell is slidably connected to the surface of the sliding rail, a hollow channel is fixedly connected to the interior of the shell, temperature sensing equipment is fixedly installed on the surface of the hollow channel, an air bag plate is fixedly connected to the interior of the temperature sensing equipment,and a push rod is movably connected to the surface of the air bag plate. The airbag plate is extruded to release gas. At the moment, the push rod is a certain distance away from the hollow channel located in the upper space in the shell. After being inflated, the blocking and holding rod can rotate to a state as shown in Figure 5, and the restriction of the shell is lost. In addition, the upper air spring is inflated and
