If the heat is not discharged in time, it will easily affect the stability and reliability of the system operation. In addition, the long-term accumulation of heat can easily cause the medium frequency static power supply to fail, making it difficult to work normally, resulting in a decrease in overall performance.

[0015] Through the above technical solution, after the line passes through the A threading hole, it can be connected to the external electrical equipment through the B threading hole, and the winding rod can wind up the excess wires to avoid the phenomenon that the line is easily tangled due to confusion, which affects the subsequent disassembly and assembly of personnel.

[0016] As a further improvement of the above solution, a third slide groove is provided at the top and bottom of the front side of the protective box, the interior of the third slide groove is slidably connected to a sealed door via a third slider, and an observation window is provided in the middle of the front side of the sealed door.

[0017] Through the above technical solution, the observation window can facilitate personnel to observe the working conditions of the internal power supply body from the outside, and the sealed door can seal the protective box to prevent external impurities and dust from entering the interior and affecting the normal operation of the power supply body.

[0018] As a further improvement of the above solution, a handle is fixedly connected to one side of the front of the sealing door, a rotating seat is fixedly connected to one side of the outer surface of the protection box, and a stop block is fixedly connected to the inside of the rotating seat.

[0019] Through the above technical solution, personnel can limit the sealing door by rotating the stop block to prevent the sealing door from sliding by itself through the third slider, which may easily cause the sealing door to fall and break.
