Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

The utility model provides an anti-interference high and low voltage switchgear as shown in Figure 1-2, including a cabinet body 1, a vertical partition 14 welded and fixed in the middle of the cabinet body 1, and various electronic devices arranged on the upper end of the horizontal partition 8. Device 7, a number of air vents 10 evenly opened on the rear side wall of the cabinet body 1, a number of legs 3 arranged symmetrically at the lower end of the cabinet body 1, and a cabinet door 2 provided by rotating the front side of the cabinet body 1, and the upper end of the cabinet body 1 is set There is a heat dissipation mechanism 4, a horizontal partition 8 is slidably arranged between the vertical partition 14 and the side wall of the cabinet body 1, and the lower end of the horizontal partition 8 is slidingly provided with two inserting plates 12 through a rectangular sleeve 13, so that The lower side of the board 12 is fixed with a fixed block 15, and the fixed block 15 is slidably arranged in the square hole groove 16 provided on the lower side of the rectangular sleeve 13. A spring 17 is arranged between the boards 12, and the cabinet Several positioning pieces 9 are fixedly arranged on the side walls of the body 1 and the vertical partition 14 , and the inserting plate 12 is inserted between the positioning pieces 9 .

Specifically, rubber strips 5 are laid on the upper and lower sides of the positioning piece 9, and the distance between the positioning pieces 9 is slightly greater than the height of the board 12. The friction force between the sides of the inserting plate 12 ensures that the positioning piece 9 clamps and fixes the inserting plate 12 and ensures the stability of the positioning of the transverse partition plate 8 .

Specifically, both sides of the transverse partition 8 are fixedly equipped with slide bars 11, and the ends of the slide bars 11 are slidably arranged in the chute 6 provided on the inner side wall of the cabinet body 1, and the end faces of the slide bars 11 are in contact with the The bottom surface of the chute 6 is in close contact, and the movement of the transverse partition 8 in the cabinet body 1 from left to right and forward and backward is limited by the sliding of the slide bar 11 inside the chute 6, so as to avoid shaking after the transverse partition 8 is positioned. In this case, the stability of the placement of the diaphragm 8 is further enhanced, and at the same time, the longitudinal position of the diaphragm 8 is conveniently adjusted.

Specifically, the positioning piece 9 is made of brass, and the positioning piece 9 is welded and fixed to the side walls of the cabinet body 1 and the vertical partition 14 horizontally. When the heat dissipation mechanism 4 starts to work, the air in the cabinet body 1 will flow , the air passes between the positioning pieces 9, thereby taking away the heat on the positioning pieces 9, so that the positioning pieces 9 have the function of a heat sink, and enhance the heat dissipation effect.

Specifically, the heat dissipation mechanism 4 is composed of a metal connecting pipe 41 and a heat dissipation fan 42. The cabinet body 1 communicates with the air inlet of the heat dissipation fan 42 through two metal connection pipes 41 fixedly arranged on the upper end. The cabinet body 1 The width of the inner cavity is greater than the width of the transverse partition 8, and the two metal connecting pipes 41 are used to suction the inner cavity of the two cabinets 1 separated by the vertical partition 14, so that the inside of the cabinet 1 is separated into two separate cavities.
