Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, specifically to a spring operating mechanism. Background Technology

[0002] The spring operating mechanism is a core driving component of high-voltage switchgear, which uses a pre-compressed energy-storing spring to release energy and drive the opening and closing actions. This mechanism typically includes key components such as the opening / closing half-shaft, the tripping device, and the linkage assembly. The opening / closing half-shaft, as the pivot of the mechanical interlock, directly controls the mechanism's tripping and resetting by its rotation angle, thus affecting the reliability and accuracy of the switch's opening and closing status. In existing technologies, the transmission mechanism between the opening / closing button and the opening / closing half-shaft is complex in design, with numerous parts, increasing assembly difficulty and production costs.
