High-altitude transformer with detection structure

The utility model provides a high altitude transformer with a detection structure, which comprises a transformer main body, the transformer main body is provided with a detection assembly, the detection assembly comprises a detection cylinder, and the inside of the detection cylinder is slidably connected with a pull rod. After the transformer main body is installed, the movable disc is pulled to drive the drawing disc to move, so that negative pressure is generated in the detection cylinder, the negative pressure sucks the movable disc, and when the sealing performance of the transformer main body is poor, air enters the transformer main body and then is separated from the transformer main body, so that the sealing performance of the transformer main body is improved. The negative pressure in the transformer main body disappears when the negative pressure in the transformer main body disappears, so that the detection disc is in contact with the trigger switch, the trigger switch controls the alarm to sound,
