通过分析电抗器故障情况,得出电抗器匝间短路、接地短路和外部短路时电气量之间的特殊关系。并在此基础上建立构成常见电抗器保护装置匝间保护的工作原理和电抗器电气量的特殊关系,结合各常见装置具体情况推导归纳出有针对性的试验方法,经现场试验验证该试验方法的可行性。
Abstract:
 This paper obtains the electrical quantity special relationship of turn-to-turn short circuit,earth short circuit and exterior short circuit for reactor by analyzing breakdown situation of reactor.And according to the difference of work principle of circle protects for several kinds of common reactor protective device which is based on this relationship and the special relationship of reactor electrical quantity,this paper has induced pointed testing method and confirmed the feasibility of the testing method by field test.
