The Operating Mechanism Of An Sf6 Circuit Breaker Must Release Energy Before Maintenance.

By releasing the spring or hydraulic energy stored in sf6 circuit breaker operating mechanism, the mechanism can be brought to a static and controllable state. If disassembly or maintenance is performed while the energy is still stored, sf6 circuit breaker spring mechanism may experience unexpected movement or impact, affecting the safety of maintenance personnel. After releasing the energy, it is necessary to check whether the relevant mechanical connections are loose or have any play, to determine if they have shifted or deformed due to the release of stored energy. Following the energy release procedure correctly before operating the mechanism can eliminate potential hazards for subsequent maintenance work.
