电力变压器继电保护国标与美标的差异探讨

The Difference Between Chinese Standard and American Standard of Power Transformer Relay Protection

基于GB/T 14285和IEEE Std 242,探讨国标和美标在电力变压器继电保护方面的差异,论文主要对比分析了故障及异常运行状态保护的差异,油浸变压器瓦斯保护的差异,变压器引出线、套管及内部的短路故障保护的差异等,以期加深设计者对继电保护国际标准及国内标准的理解,增强设计者在实际工程中对继电保护设计应用的掌控能力.

Based on GB/T 14285 and IEEE Std 242,this paper explores the difference in Chinese standard and American standard about the power transformer relay protection.The thesis mainly analysis the differences from the aspects as the fault and abnormal running state protection,oil-immersed transformer gas protection,protection of transformer outlet line,bushing and internal short circuit fault,etc.,in order to deepen the designers understanding of relay protection of international standards and domestic standards,enhance the designers in the practical engineering application of relay protection design of control.
