Distinguish between circuit breaker
It is often said that the air switch and circuit breaker have what distinction? Usage and function of the air switch and circuit breaker is almost the same, but in general, the air switch is used in electrical overload load smaller occasions, circuit breakers used in relatively large load point. According to the use of quenching medium, type circuit breaker comprises an air circuit breaker and an air switch, vacuum circuit breakers, SF6 breakers, oil circuit breaker, electrical design of civil buildings due to the low voltage is 220~380V, the arc medium arc circuit breaker are air, so air switch or breaker on. But for the power management system, to deal with specific recognition.
In recent years, along with the vacuum circuit breaker technology continues to progress, the technique of vacuum circuit breaker is mainly manifested in the large capacity, low voltage, intelligence and miniaturization. And this progress is due to the development of technology, vacuum interrupter technology and the adoption of new technology, new material and new operating technique results. This technique can be used as alternative future except outside the traditional motor technology, will also for the DC motor to extend more wider space for the development and application. Such as the development of large capacity DC motor instead of HVDC power supply of AC synchronous generator and converter equipment, not only can save a lot of converter station construction costs, but also can greatly reduce the power loss.
After the circuit breaker can be toward the special type, multifunctional, low voltage, intelligent direction.
