摘要
变压器的电流差动保护能正确区分区内区外故障,且不需与其他元件的保护配合,可以无延时地切除区内各种故障,在电力系统继电保护中具有其重要性和代表性。文章对变压器差动保护误动作进行了分析,并提出了相应的防范措施,可为今后同类情况提供参考。
The current differential protection can distinguish the failure in region outside without protection coordination with other components,can removed various fault without delay,has an importance and representative in the power system.This paper analyzes transformer differential protection malfunction,proposes the corresponding preventive measures,can provide a reference for future similar cases.
