Switch on-off spring operating mechanism of grounded switch and isolation switch

Abstract

The invention relates to a switch on-off spring operating mechanism of a grounded switch and an isolation switch, the design of the switch on-off spring operating mechanism is mainly as follows: grounded clutch turning wheels and isolation clutch turning wheels are respectively arranged between a grounded gear shaft and a grounded energy storage shaft, and between an isolation gear shaft and an isolation energy storage shaft; the grounded clutch turning wheels and the isolation clutch turning wheels consist of outer wheels, inner wheels, clutch paws and torsional springs; the outer wheels are actively connected to the inner wheels and hinged with the clutch paws through the torsional springs; the clutch paws are tightly fastened with a paw grooves of the inner wheels in the action of the torsional spring; the grounded output shaft and the isolation output shaft are the same output shaft; the grounded output shaft is fixedly connected to a grounded driving crank arm; a grounded transmission crank arm for linking the clutch paw is arranged between the grounded driving crank arm and the grounded clutch runner; the isolation output shaft is fixedly connected to an isolation driving crank arm; and an isolation transmission crank arm for linking the clutch paw is arranged between the isolation driving crank arm and the isolation clutch turning wheel. The switch on-off operating mechanism disclosed by the invention is compact in structure, reliable, convenient and safe in operation and use and suitable for being used as a double-switch correlation lock operating mechanism.

Description

technical field [0001] The invention relates to a switch operating mechanism, which is an opening and closing spring operating mechanism of a grounding switch and a disconnecting switch. Background technique [0002] In the existing high-voltage switch, the isolating switch and the grounding switch are two independent and connected switchgears. When the isolating switch is in the closed state, the grounding switch should be opened and cannot be closed; when the isolating switch is in the open state, the grounding switch can be closed; Closing; when the grounding switch is in the open state, the isolating switch can be closed. In order to realize the requirement of interlocking between the operating isolating switch and the grounding switch, two operating mechanisms plus an interlocking device are often used on the market to achieve this. However, this structure is relatively complicated and has a large volume, which is not conducive to manufacturing and assembling, and the...
