Pressure releasing passage of switch cabinet

Abstract

The invention relates to a pressure releasing passage of a switch cabinet. A pressure releasing cover covers a pressure releasing window in a top plate of a cabinet body of the switch cabinet, one side of the pressure releasing cover is fixedly connected with the top plate of the cabinet body by a plastic screw, the other side of the pressure releasing cover is hinged with the top plate of the cabinet body via a hinge, a groove s formed in a top plate of the pressure releasing cover and is sunken, two side walls of the groove incline towards a downward and outward direction along a vertical central line of the groove so that the two side walls of the groove form a slanted inclined opening, through holes are formed in the two side walls of the groove, and the two sides of the pressure releasing cover are connected to the top plate of the cabinet body of the switch cabinet by the plastic screw and the hinge. The opening resistance of the pressure releasing cover can be reduced, the pressure releasing cover rotates and is turned over along the hinge after being opened and cannot be ripped off and lost, and the pressure releasing passage is reliable to install and connect; the groove is formed in the top plate of the pressure releasing cover and is sunken, the two side walls of the groove incline to form the slanted inclined opening, an edge of the groove is convenient to grasp, the carrying and installation operation is convenient, the through holes in the two side walls of the groove form auxiliary pressure releasing holes, and the pressure releasing effect is improved.

Description

technical field [0001] The invention relates to a pressure relief channel of a switch cabinet. Background technique [0002] The switchgear products in the power transmission and distribution control equipment in the power industry need to have a pressure relief channel on the top to quickly discharge the high pressure in the cabinet caused by a sharp rise in temperature when a fault such as a short circuit or arc occurs during normal operation. Traditional switchgear products The pressure relief channel is generally provided with a pressure relief window on the top of the switch cabinet, and the top of the window is covered with a pressure relief plate, and the two sides of the pressure relief plate are fixedly connected to the top plate of the switch cabinet by screws. Quickly break through the plastic screws and open the pressure relief plate to open the pressure relief channel. Both sides of the pressure relief plate are fixedly connected at the same time. The high press...

[0002] The switchgear products in the power transmission and distribution control equipment in the power industry need to have a pressure relief channel on the top to quickly discharge the high pressure in the cabinet caused by a sharp rise in temperature when a fault such as a short circuit or arc occurs during normal operation. Traditional switchgear products The pressure relief channel is generally provided with a pressure relief window on the top of the switch cabinet, and the top of the window is covered with a pressure relief plate, and the two sides of the pressure relief plate are fixedly connected to the top plate of the switch cabinet by screws. Quickly break through the plastic screws and open the pressure relief plate to open the pressure relief channel. Both sides of the pressure relief plate are fixedly connected at the same time. The high pressure release resistance in the cabinet is large. After the plastic screws on both sides of the pressure relief plate break through at the same time, the pressure relief plate is completely separated from the top plate of the switch cabinet, and it is easy to be lifted. Lost; and the upper surface of the pressure relief plate is flat, it is inconvenient to transport and install
