| 摘 要： | 介绍了在励磁系统中灭磁的基本方式,利用氧化锌电阻作为大容量吸能元件,使灭磁开关快速熄弧开断,并移能到氧化锌阀片中进行能量消耗,可实现同步发电机快速灭磁。采用该方式灭磁,可加快灭磁时间,减少开关触头磨损老化及降低对磁场断路器弧压的苛求,对新老机组灭磁回路设计和改进具有普遍意义。

| Abstract: | Introduction was made to the basic methods of magnetic blowout in excitation systems,by using zinc oxide resistance as large capacity energy absorbing element to make magnetic blowout switch in quick arc blowout breaking and transferring energy to zinc oxide resistance to carry out energy consumption which can realize synchronous generator quick magnetic blowout.With adoption of this method to have magnetic blowout can speed up magnetic blowout time,reducing switch contacts wearing and ageing and lowering down the require- ments for magnetic field circuit breaker arc pressure,having common significance to new and old generator sets magnetic blowout circuit design and improvement. |
