Switch cabinet and its valve linkage system

Abstract

The invention relates to a switch cabinet and a valve linkage system thereof. The valve linkage system comprises an upper valve device and a lower valve device which are arranged in the up-down direction of the switch cabinet, each of the upper valve device and the lower valve device comprises a telescopic valve structure, and a synchronous transmission mechanism for driving the two telescopic valve structures to synchronously stretch out and retract is arranged between the two valve devices. The upper valve device and the lower valve device are driven by the synchronous transmission mechanismto synchronously stretch and retract, synchronous movement of the upper valve and the lower valve is achieved, and the problem that in the prior art, an upper valve driving system and a lower valve driving system are adopted for driving the valves to be opened and closed respectively so that the upper valve and the lower valve cannot accurately achieve synchronous movement is solved.

Description

technical field [0001] The invention relates to a switch cabinet and a valve linkage system thereof. Background technique [0002] At present, there are many types of switch products produced and applied in the market at home and abroad. The general structure type is front, middle, rear and left, middle, and right arrangements. When the products arranged in the front, middle and rear are fixed, the compartment The division is not obvious, the continuity of operation is lost and the protection level is low; while the three-phase arrangement arranged on the left, middle and right is mostly a removable metal-enclosed switchgear, which needs a valve to open and close the charged body. Hanging plate, lower hanging plate, left and right driving crank arms, connecting rod, guide rod and other components. The crank arms on both sides are driven by the rocking in and out of the chassis, and the crank arms drive the pull rod to move to realize the opening and closing of the valve, an...

Problems solved by technology

[0005] The purpose of the present invention is to provide a valve linkage system to solve the problem in the prior art that the upper valve and the lower valve drive system respectively drive the opening and closing of the valves, resulting in the inability of the upper valve and the lower valve to accurately realize the synchronous movement; the present invention The purpose is also to provide a switchgear that solves the above problems
