摘要
针对变压器后备保护整定过程中遇到的问题,结合生产实际,重点对较为特殊的三卷变压器三侧有电源、两侧有电源的情况下后备保护的整定进行了分析,提出了解决方案,为日后继电保护定值的整定提供参考。
The problems during the course of transformer mothball protection setting are introduced, then considering practicality production the paper analyses how to set the transformer mothball protection in face of special conditions such as three loops transformer with three powers or two powers, and brings out the method at the same time as the reference of protection setting daily.
