detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. 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.

Please refer to Figures 1 to 3. In the embodiment of the utility model, a dust-free high-voltage power distribution cabinet includes a cabinet body 1 and a top cover 8. The cabinet body 1 is a cuboid cavity structure, and the top cover 8 is located at The top of the cabinet body 1, the cabinet body 1 includes four heat insulation boards 2 connected in sequence and a base 3 fixed on the lower end of the heat insulation boards 2, the base 3 is provided with a mounting seat 4 for fixing an electric device, the An air inlet 5 is provided between the base 3 and the heat insulation boards 2 on the left and right sides of the cabinet body 1. The air inlet 5 is opened along the length direction of the heat insulation board 2 on the side of the cabinet body 1, and a filter screen is installed on the air inlet 5 6. The upper section of the top cover 8 is triangular in shape, and the cross-sectional area of the bottom surface of the top cover 8 is larger than that of the top section of the cabinet body 1. An air outlet 7 is provided at the connection between the top cover 8 and the cabinet body 1, and the air outlet 71 is provided with Fan 71, the fan 71 is located between the inner side of the top cover 8 and the heat shield 2.
