摘要
阐述了110 kV变压器中低压侧加装限时速断保护的必要性,并以实例进行保护定值整定分析,提出了加装限时速断保护后出线保护定值整定优化原则,对地区电网变压器保护的配置和整定有很强的参考价值。
This paper elaborates the necessity to install time-limited quick-break protection in low-pressure side of the 110 kV transformer, illustrates the setting analysis of protection setting value, and provides the optimal principle.It is a reference for the configuration and setting of transformer protection in local electric network.
