And also introduces the principle and application of another new type quick high pressure vacuum circuit breaker with electromagnetic repulsion mechanism. This kind of quick high pressure circuit breaker can depart the contacts off within 1 ms, to switch off the currency within one wave cycle. 还介绍了另一种新型的采用电磁推斥操动机构的快速高压真空断路器的原理及应用,这种快速真空断路器可在lms内使触头分离,在一周波内开断电流。
The gas pressure within vacuum interrupter has a direct effect upon the properties of vacuum circuit breaker. 真空灭弧室的内部气体压力直接影响真空断路器的性能。
