Abstract

An electrical switch cabinet using a pneumatically opened and closed sliding door comprises a cabinet body (7) and a sliding door (8) disposed at the front opening of the cabinet body (7). A locking bump (70) is fixedly arranged in a position, facing the opening, in the middle of the frame of the cabinet body (7). A drag mechanism is arranged in a position of a side, corresponding to the locking bump (70), of the sliding door (8). The drag mechanism comprises an installation block (82) fixedly installed on the body of the sliding door (8) and a guide rail block (81) fixedly connected with the installation block (82). The guide rail block (81) and the installation block (82) form a cavity. The guide rail block (81) is provided with a contour part sequentially comprising a vertical blocking section (810), a concave horizontal section (811), a transitional slope section (812) and a convex horizontal section (813) in the front-rear direction from left to right on a side, facing the cavity, of the guide rail block (81).

Description

technical field [0001] The application relates to the field of electrical cabinets, in particular to an electrical switch cabinet using a pneumatically opened and closed sliding door. 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 a pneumatically opened and closed sliding door, which can overcome the above-mentioned defects of the prior art. [0004] According to the present invention, ...
