A high-voltage electrical switchgear, comprising a box body and an isolation net, a protruding air inlet cover is provided on the top of the box body, the cross section of the air inlet cover is a right-angled trapezoid, and strips shaped air inlet, the upper half of the box door of the box is provided with see-through glass, the lower half is provided with a louver-shaped air outlet, and the top of the box is provided with a strip-shaped through hole near the edge of the box door. The net is inserted into the strip-shaped through hole, and the top of the isolation net is also provided with a baffle perpendicular to the isolation net. The size of the baffle is larger than the strip-shaped through hole, and the side of the box is provided with a protective beam relative to the edge of the box door. , a magnetic strip is symmetrically arranged in the middle of the protective beam.

Further, the contact surface between the baffle plate and the top of the box is provided with anti-slip stickers.

Further, the isolation net includes cross-braided insulating wires.

Further, the number of magnetic stripes is 2.

Further, the bottom of the box is provided with a moisture-proof pad.

It should be noted that the air intake hood on the top of the box and the louver-shaped air outlet on the door form an air circulation and heat dissipation, which increases the effect of heat dissipation. There is an insertable isolation net on the top, which is limited by the baffle to prevent the door from being closed. Closing is easy to cause electric shock safety, the setting of see-through glass is convenient for maintenance personnel to patrol, and the bottom is equipped with a moisture-proof pad to prevent moisture in the box and ensure the safety of electricity use.

Beneficial effect:

The utility model provides a high-voltage electrical switchgear, which adopts circulation heat dissipation, the unique design of the air inlet and the air outlet has a dustproof function, the isolation net has a good safety isolation function, and the see-through glass is also convenient for inspection. Compared with the traditional electrical switchgear , improved heat dissipation, safety and moisture resistance.
