Isolated grounding three-gang mechanism

The invention belongs to the technical field of power switch equipment, and particularly relates to an isolated grounding three-gang mechanism. The isolated grounding three-gang mechanism comprises: an isolation module, an output module, an energy storage spring, a grounding module and an arc extinguishing chamber module, wherein the isolation module and the grounding module achieves output in cooperation with a roller on the output module through a U-shaped collision plat. The energy storage spring is disposed between the isolation module and the grounding module. Through the increase and decrease of the arc extinguishing chamber modules, a single-shaft output mode that drives the isolation rotating shaft three-gang to close or open to a double-output mode that drives the isolation rotating shaft to achieve isolation and close and open and drives a grounding vacuum arc extinguishing chamber to be grounded. The traditional transmission method is changed and the structure is simplified. 本发明属于电力开关设备技术领域，具体涉及种隔离
