Abstract

Provided is an electrical switchgear enabling dual push rods to be driven in a pneumatic manner. The electrical switchgear includes a cabinet body (7) and a sliding door (8) positioned in an opening at the front end of the cabinet body (7). A locking protrusion (70) facing the opening is fixedly disposed in the middle of a frame of the cabinet body (7). One side of the sliding door (8), corresponding to the locking protrusion (70), is provided with a drag mechanism. The drag mechanism comprises a mounting block (78) fixedly arranged on a body of the sliding door (8), and guide rail blocks (81, 181) fixedly connected to the mounting block (78). The opposite surfaces of the guide rail blocks (81, 181) are both provided with profile portions that sequentially include vertical block segments (810, 1810), inward recessed horizontal segments (811, 1811), transition inclined plane segments (812, 1812) and outward protruding horizontal segments (813, 1813).

Description

technical field [0001] The application relates to the field of electrical cabinets, in particular to an electrical switch cabinet using pneumatically driven double push rods. Background technique [0002] The operation door of the electrical switchgear needs to be opened and closed frequently to operate or maintain the electrical switches therein. Moreover, in some occasions, the electrical switchgear needs to have watertight airtight performance to ensure the normal and reliable operation of the internal electrical switching elements. However, under frequent switching, it is difficult to guarantee this airtight performance, and it is even more difficult to realize it under operation control. Contents of the invention [0003] The object of the present invention is to provide an electrical switchgear using pneumatically driven double push rods, which can overcome the above-mentioned drawbacks of the prior art. [0004] According to the present invention, an electrical sw...
