牵引变压器缺相运行故障分析及对策

Analyzing and Countermeasures for Lack-of-phase Operation Faults of Traction Transformers

由于进线电源缺相及开关故障,近年来多次发生牵引变压器缺相运行故障,造成电气化铁路供电中断,严重影响铁路运输秩序。本文分析了造成变压器缺相运行的原因及故障现象,并制定相应处理措施,为快速判断故障性质和正确处置提供理论依据,保证牵引变压器安全可靠运行。

Due to the lack-of-phase of incoming lines and faults of switches,the lack-of-phase operational faults of transformers occurred frequently in recent years and induced to power supply interruption of electrified railways and impacted severely the railway transportation organization.The paper analyzes the causes of lack-of-phase operation and phenomenon of faults of transformers,establishes corresponding disposal measures,provides a theoretical basis for a rapid judgment of natures of faults and correct treatment for safety and reliable operation of traction transformers.
