Embodiment Construction

[0023] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] The specific embodiment of the switching device provided by the present invention, such as figure 1 As shown, the switching device in this embodiment is specifically a grounding switch, and the moving contact 2 of the grounding switch moves in the up and down direction to engage and separate from the corresponding static contact. The structure and cooperation of the moving contact and the static contact The relationship is the same as that of the moving and static contacts in the earthing switch in the prior art, and will not be repeated here.

[0025] The moving contact 2 of the grounding switch is driven up and down by a spring operating mechanism. The spring operating mechanism includes a mounting frame (not shown in the figure). The mounting frame can adopt the mounting frame structure of the spring operating mechanism in the prior art. Equip...

Abstract

The invention relates to a switching device and a spring operation mechanism thereof. The spring operation mechanism comprises an installation frame, wherein the installation frame is provided with an output shaft; the output shaft is provided with a closing position and an opening position; a driven connecting lever is fixedly arranged on the output shaft; the output shaft is rotationally sleeved with a driving connecting lever; the driving connecting lever has a release travel in a rotation travel; the output shaft is provided with a stop structure; the installation frame is rotationally provided with a retainer; the retainer is provided with a stop part; the stop part is used for being in stop fit with the stop structure to stop and position the output shaft at the corresponding closing position or opening position before the driving connecting lever strikes the driven connecting lever; the retainer is provided with a locking position for making the stop part and the stop structure in stop fit in the rotation travel; the retainer is also provided with an unlocking part; the unlocking part is struck by the driving connecting lever on the corresponding release travel to compel a retaining bar to rotate away from the locking position. The output shaft is prevented from rotating before the driving connecting lever strikes the driven connecting lever by using stopping and positioning of the retainer on the output shaft, and the safety performance of the switching device is improved.

Description

technical field [0001] The invention relates to a switch electrical appliance and a spring operating mechanism thereof. Background technique [0002] The fast earthing switch is an important component of the gas-insulated metal-enclosed switchgear (GIS). It is arranged on the side of the outgoing line interval switch of the outgoing circuit. Grounded, use a circuit breaker to cut off the fault current. [0003] The structure of the existing quick grounding switch is as the quick grounding switch device disclosed in the Chinese utility model patent whose authorized announcement number is CN203521278U, including a housing, which is provided with a transmission mechanism, a moving contact and a terminal block, and the transmission mechanism and The moving contact is connected by transmission, and the transmission mechanism includes a rotating shaft and a connecting rod. The rotating shaft is provided with a crank arm, and the turning arm is connected to the moving contact thro...
