A permanent magnet sealed vacuum circuit breaker is an indoor high-voltage vacuum circuit breaker that uses a permanent magnet holding mechanism and electronic control (permanent magnet mechanism), equipped with epoxy resin sealed poles. The permanent magnet circuit breaker utilizes the magnetic force generated by a high-performance permanent magnet (such as neodymium iron boron) to maintain the circuit breaker's closed or open state, replacing the complex mechanical locking device of traditional spring mechanisms.
advantages
The advantages of a permanent magnet sealed vacuum circuit breaker are its extremely simple structure with almost no vulnerable mechanical latches, linkages, or cams. It also boasts very high reliability: an extremely long mechanical lifespan. Furthermore, it has extremely low energy consumption: no electrical energy is consumed in the holding state.
Traditional spring-operated circuit breakers use a spring-energy-storage mechanism. This mechanism uses an electric motor (or manual operation) to compress and store energy in the spring, which is then held in place by a mechanical latch. When a tripping or closing command is received, the latch is released, rapidly releasing the stored mechanical energy and driving the circuit breaker to complete the tripping or closing operation. It is an indirect energy-operated mechanism, meaning energy is stored first, then the action is performed.
advantages
The energy storage system of a traditional spring-operated circuit breaker includes: an energy storage motor, a reduction gear, and a closing spring.
Advantages of traditional spring-operated circuit breakers:
The technology for manufacturing spring-operated circuit breakers is quite mature, and their operational experience and performance have been thoroughly verified.
Traditional spring-operated circuit breakers are highly independent and do not depend on the instantaneous power of the power grid. Only energy storage is required to complete one tripping or closing operation.
Traditional spring-operated circuit breakers are relatively inexpensive and easy to operate manually, which is an important emergency backup function.
