Problems solved by technology

[0002] There is no valve in the original domestic design of the cabinet. When the handcart is shaken out, the primary static contact is exposed outside. It is very unsafe when checking the circuit breaker room.
For maintenance safety, an insulating valve was added to the design of the cabinet in the future, but the insulating valve failed to seal the primary conductive part well. At the same time, the insulating valve only separated the primary conductive part and did not form the same potential with the cabinet. , so that there is an electrostatic problem in the insulating part, and there is a certain safety hazard to the human body.

Abstract

The invention discloses a novel switch cabinet valve mechanism. A large connecting rod I and a large connecting rod II can respectively rotate around a fixed pin I and a fixed pin II; a valve plate I and a valve plate II are hinged with each other through a cross rod I; a valve plate III and a valve plate IV are hinged with each other through a cross rod II; the valve plate I can rotate around a lower valve shaft; the valve plate IV can rotate around an upper valve shaft; the valve plate II is clamped in a lower valve chute through a screw stem I; the valve plate III is clamped in an upper valve chute through a screw stem II; the large connecting rod I and the large connecting rod II are respectively hinged with a small connecting rod I and a small connecting rod II; the top ends of the small connecting rod I and the small connecting rod II are respectively connected with the screw stem I; and the screw stem I is connected with the screw stem II through a wire rope. The mechanism can realize automatic opening or closing of the valve, and is characterized by strong integration performance, convenient installation, high structural strength, strong adaptability and the like.

Description

technical field [0001] The invention relates to a shutter mechanism of a switch cabinet. Background technique [0002] The original domestically designed cabinet does not have a valve. When the handcart is shaken out, the primary static contact is exposed outside. It is very unsafe to check and repair the circuit breaker room. For maintenance safety, an insulating valve was added to the design of the cabinet in the future, but the insulating valve failed to seal the primary conductive part well. At the same time, the insulating valve only separated the primary conductive part and did not form the same potential with the cabinet. , so that there is an electrostatic problem in the insulating part, and there is a certain safety hazard to the human body. Contents of the invention [0003] In order to solve the above existing problems, the present invention provides a novel switchgear valve mechanism, and the technical solution it adopts is: [0004] The mechanism includes...
