摘要
分析了变压器降压运行时参数的变化,以大容量发变组自并励励磁系统的励磁变为例,探讨了其正常和降压运行时高压侧电流保护的整定原则,供有关技术人员参考。
The parameters change for reducing voltage operation of transformer was analyzed.Taking the self-shunting excitation system exciting transformer of large capacity generator-transformer unit for example,the high voltage side current protection setting principles for normal and reducing voltage operation were discussed which provided the reference for the related technical personnel.
