Problems solved by technology

In the prior art, the door of the switchgear used outside the substation is usually provided with ventilation holes, which are used to circulate the gas in the switchgear in summer high temperature weather, effectively preventing the power equipment in the switchgear from High temperature damage. At this time, when it rains in the outdoor environment, rainwater can enter the switch cabinet through the vent hole, thereby causing damage to the operation of the electrical equipment in the switch cabinet. Therefore, it is urgent to install a Sealed waterproof mechanism

Abstract

The invention relates to the technical field of switchgear, and discloses an electrical switchgear, which includes a housing, in which a moving chamber with an opening facing backward is provided, and the left and right side walls of the moving chamber are provided with moving grooves along the front and rear directions. On the front side wall, there are first ventilation slots arranged along the left and right directions at intervals; a slidable moving plate is arranged in the moving cavity, and a slider extending into the corresponding moving groove is arranged on the moving plate, and there are intervals along the moving plate. The second ventilation grooves arranged in the left-right direction and staggered from the first ventilation grooves. Through the above structure, the present invention adjusts the sealing and air permeability of the moving chamber by adjusting the distance between the moving plate and the front side wall of the moving chamber due to the arrangement of the moving chamber, the moving plate, the first air-permeable groove and the second air-permeable groove.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to an electrical switch cabinet. Background technique [0002] The power switchgear is an important electrical equipment for switching, control and protection in the power system. Switchgear is mainly composed of measuring equipment, circuit breakers, isolating switches, load switches, operating mechanisms and various protection devices, and is widely used in substations, power plants and other places. In the prior art, the door of the switchgear used outside the substation is usually provided with ventilation holes, which are used to circulate the gas in the switchgear in summer high temperature weather, effectively preventing the power equipment in the switchgear from High temperature damage. At this time, when it rains in the outdoor environment, rainwater can enter the switch cabinet through the vent hole, thereby causing damage to the operation of the electrical equipm...
