Abstract
The invention discloses a solid insulating ring main unit fuse with a one-shaft double-grounding interlocking device. An original solid insulating fuse is not provided with a lower grounding interlocking device so that after a circuit breaker is grounded, a small quantity of residual electricity may exist in a circuit and thus potential safety hazards may exist during maintenance of a maintenance personnel and safety accidents are likely to happen. Included are the one-shaft double-grounding interlocking device and the solid insulating ring main unit fuse. The one-shaft double-grounding interlocking device includes an interlocking joint, an interlocking connecting lever, an interlocking rod, an interlocking driven push rod, an interlocking push rod, a small grounding interlocking installation plate, a small grounding sealing cover, a fixing shaft, a transmission shaft, small grounding moving contacts, small grounding bars and a moving-contact fixing plate. While the circuit breaker is grounded, the grounding of the fuse is also realized synchronously and the residual electricity in the circuit is released so that it is ensured that electricity quantity is zero in the circuit and the safety of the maintenance personnel is further protected.
