| 本文就工厂企业中常见的6 kV及10 kV电缆线路保护误动原因进行分析，以电流速断保护理论为依据，阐述了保护误动的原因，并结合实例说明保护定值计算中应注意的问题，对电气设计及运行人员在实际的保护配置和整定计算中具有借鉴意义。 |
| 英文摘要: |
| In this paper, the protection maloperation of common 6 kV and 10 kV cable line protection malfunction is analysed, and according to current quick break protection theory, the reason of misoperation is expounded. And combined with examples the problems that we should pay attention to in calculation of protetion setting value are explained, which can be used as a reference for the electrical design and operation personnel in the actual protection, configuration and setting calculation. |
