摘　　要：在现阶段电力死区故障处理过程中,快速切除220kV变压器死区故障是电力控制的新模式,其可以在保证死区故障合理预防的同时,为后续电力系统稳定运行提供依据。文章以某侧断路器死区故障为例,阐述了快速切除220kV变压器死区故障所有故障点及故障因素,对220kV变压器在其故障切除中的应用进行了简单的分析。以期为快速切除220kV变压器死区故障继电保护技术的合理应用提供有效的借鉴。In the current stage of power dead-time fault processing, rapid removal of 220kV transformer dead-zone fault isanew mode of power control, which can ensure the reasonable prevention of dead-time fault and provide the basis for the follow-uppower system stable operation. Taking one side circuit breaker dead zone fault as an example, this paper expounds all fault pointsand fault factors of fast removing 220kV transformer dead zone fault, and simply analyzes the application of 220kV transformer in itsfault removal, in order to quickly remove the dead zone fault of 220kV transformer relay protection technology and thus to providean effective reference for the rational application.
