摘要
介绍了新型电子控制电机(Motor drive)驱动操动机构的原理及应用;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。
It introduces the principle and application of the driving mechanism with new type electronic controlled motor drive; 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.
