AI Technical Summary
The electromagnetic lock tongue of the existing ring network switchgear extends too far, causing the grounding switch operating gate baffle to not be able to completely cover the operating gate, which poses a risk of misoperation.
An interlocking mechanism was designed, including an electromagnetic lock, a support block, a movable block, and an elastic component. When the ring main switchgear is energized, the electromagnetic lock is locked, and the lock tongue pushes the movable block to cover the operating hole. When the power is off, the movable block moves under the elastic force of the elastic component, exposing the operating hole and allowing operation.
This system prevents misoperation when the ring network switchgear is energized and facilitates operation when the power is off, thus improving operational safety and reliability.
