Interlocking in vacuum circuit breaker
1. The significance of chain control
Chain control means that when a device fails, it automatically cuts off the corresponding power supply to protect the normal operation of other equipment. Therefore, the chain control of vacuum circuit breaker can prevent the overload, short circuit and other faults in the power system from affecting and damaging other equipment.
2. Realization
To realize the chain control of vacuum circuit breakers, it is necessary to use control circuits integrated circuits and other electrical components to achieve fault detection and control. Generally speaking, the chain control is divided into three ways: mechanical chain, electrical chain and logic chain. Mechanical interlocking through the transmission mechanism to realize the connection and disconnection between different circuit breakers in the power system. Electrical interlocking relies on control switches, through the control of the current switch to carry out interlocking control. Logical interlocking uses digital logic and controllers to realize precise interlocking control.
3. Application examples
Other equipment will also be automatically cut off accordingly to avoid large-scale power failure. In addition, the realization of the chain control of vacuum circuit breakers also needs to take into account factors such as system stability and reliability to ensure the safe operation of the entire power system.
