Switch cabinet valve mechanism

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 Iis articulated with a valve plate II by a cross rod I; a valve plate III is articulated with a valve plate IV by 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 connected with a lower valve sliding groove by a screw rod I in a clamping manner; the valve plate III is connected with an upper valve sliding groove by a screw rod II in a clamping manner; the large connecting rod I and the large connecting rod II are respectively articulated 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 rod I; and the screw rod I is connected with the screw rod II by a steel wire rope. The mechanism can realize automatic opening or closing of a valve, and has the characteristics of high completeness, convenient mounting, high structural strength, high adaptability and the like.

Description

Technical field [0001] The invention relates to a valve mechanism of a switch cabinet. Background technique [0002] Initially, the cabinet designed in China did not have a valve. When the handcart was rolled out, the static contact was exposed outside, and it was not safe to repair the circuit breaker room. For maintenance safety, an insulating valve was added to the cabinet design 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 the insulating parts have static electricity problems, and there is a certain safety risk to the human body. Summary of the invention [0003] In order to solve the above problems, the present invention provides a new type of switchgear valve mechanism, the technical solution adopted is: [0004] The mechanism includes a chute plate I and a chute plate II respectively fix...

AI Technical Summary

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.
