Abstract

The invention relates to a three-station operating mechanism which comprises a support, an isolation operating shaft, a grounding operating shaft and a transmission sliding plate, the transmission sliding plate is longitudinally matched on the support in a sliding mode, and an isolation rotor assembly and a grounding rotor assembly are arranged on the two transverse sides of the transmission sliding plate. An isolation rotor of the isolation rotor assembly is linked with an isolation side linkage groove of the transmission sliding plate through an isolation shifting arm so as to push the transmission sliding plate to move between an isolation closing station and an isolation opening station. A grounding rotor of the grounding rotor assembly is linked with a grounding side linkage groove of a transmission sliding plate through a grounding shifting arm to push the transmission sliding plate to move between a grounding closing station and an opening station, the grounding rotor and an isolation rotor cannot perform grounding operation during isolation closing through an interlocking device, and isolation operation cannot be performed during grounding closing. And the overall structure is simple, and the thin design is realized.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a three-position operating mechanism. Background technique [0002] The three-position switch integrates the functions of the isolation switch and the grounding switch, and is completed by a moving knife, so that mechanical locking can be achieved to prevent the main circuit from being charged with the ground knife. closed position, open position and grounded closed position. In order to realize the closing, opening and grounding of the three-position isolation switch, it is necessary to configure an electric or manual three-position operating mechanism. The existing three-position operating mechanism has a complex mechanism, resulting in a large overall thickness of the mechanism, which is difficult to apply in some environments with strict size requirements. SUMMARY OF THE INVENTION [0003] Objective of the present invention: In order to overcome the defects existi...
