Abstract

The invention relates to the technical field of power system control equipment, and in particular relates to a mid-mounted switch cabinet static contact isolation bezel locking device which comprises a connection piece. One end of the connection piece is fixedly connected with a half-moon plate. A first locking point and a second locking point are arranged on the other end of the connection piece. The first locking point is located above the second locking point. The device further comprises a base. The half-moon plate is movably connected with the base through a pin. The half-moon plate can rotate by taking the pin as the axis. A first locking shaft pin is arranged on the first locking point. A second locking shaft pin is arranged on the second locking point. The half-moon plate is connected with one end, which is away from the pin, of the base through an extension spring. According to the invention, the problem of electric shock, which is caused by the fact that an isolation bezel is easily opened when a user detects or maintains a mid-mounted switch cabinet and carries out improper operation in the prior art, is solved.

Description

Technical field [0001] The invention relates to the technical field of power system control equipment, and in particular to a locking device for a static contact isolation baffle plate of a central switch cabinet. Background technique [0002] Mid-mounted switch cabinets have been widely used in power control systems. In the existing technology, when the switch handcart slowly rolls into the mid-mounted switch cabinet from the inspection position, the organs on both sides of the handcart contact and collide with the mid-mounted switch cabinet. The two rollers on each side of the inner two sides, as the handcart rolls inward, the four rollers on both sides are forced, so that the four rollers through the connecting rod drive the line side baffle to move down and drive the bus side baffle Move upward, so that the line side baffle and bus side baffle are opened. When the switch trolley rolls out of the switch cabinet, the four rollers are no longer stressed, the busbar side baffle ...
