用同步发电机突然短接现象的分析设计大容量真空断路器

Study on Analysis of Suddenly Short-circuit of Synchro-Generator for Protecting to Design High-capacity Vacuum Circuit Breaker

本文着重介绍了用超导体线圈磁链不变原则下,对发电机出口端突然短接和ψ0=0时的分析。超瞬变和瞬变的电抗、突然三相短接电流、电抗Xd′′和Xd′的数值,两相和单相突然短接的电流以及突然短接的时间常数作了详细的阐述。可作为设计大容量真空断路器的参考。

The Paper analysis a Synchro-Generator under suddenly short-circuit including with ψ 0 = 0.And describes three-phase under suddenly short-circuit condition, super transient reactance and transient reactance, suddenly three-phase short-circuit current, X d′′ and X d′ reactance, suddenly short-circuit current of 2 phase and single phase, time constant of suddenly short-circuit etc. for designing high-capacity vacuum circuit breaker references.
