When in use, the temperature inside the electrical equipment is sensed by the sensor 2 and the temperature value is displayed through the display screen 1. At the same time, the temperature inside the electrical equipment heats the air in the card sleeve 7. The air in the card sleeve 7 expands and conducts the air pressure to the sleeve 8 through the connecting pipe 12, pushing the piston 13 in the sleeve 8 to the right until the piston 13 drives the button 16 to press against the lead screw 15. At this time, the temperature value sensed by the sensor 2 also reaches the alarm value. Then, the sensor 2 and the button 16 simultaneously punch the electric bell 20 to carry out the alarm work. Even if a certain alarm mechanism fails, the alarm work can still be carried out smoothly to ensure the working safety of the electrical equipment. When the alarm control is inaccurate due to air leakage in the card sleeve 7 and the sleeve 8, according to the temperature value displayed on the display screen 1, rotate the scale mark on the lead screw 15 to the outer side of the sleeve 8, and introduce air through the inlet 17 until at this temperature, the piston 13 drives the button 16 to move to the left end of the lead screw 15, so that the electric bell 20 is turned on, and the leaked gas in the sleeve 8 can be replenished to ensure the accuracy of temperature alarm through air pressure.
