摘要
为便于供电运营人员在日常电气设备预防性试验检修中能及时发现潜在的故障和隐患,本文对某电气化高速铁路牵引变电所变压器故障进行梳理分析,重点对故障所用变诊断过程中的一些电气试验项目及数据进行研究。研究表明:(1)设备制造厂家对运行在高寒、高海拔环境中的设备应增大绝缘裕度;(2)运营单位须加强设备检测、监测手段,缩短设备试验检查周期,使电气设备可靠运行。分析结果可为同类项目提供借鉴。
In order to facilitate power supply operators to timely find potential faults and hidden dangers in daily preventive test and maintenance of electrical equipment, this paper sorts out and analyzes transformer faults in the traction substation of an electrified high-speed railway, focusing on some electrical test items and data in the process of fault diagnosis. Research shows that:(1) equipment manufacturers should increase the insulation margin for equipment in the cold and high altitude environment;(2) the operating company shall strengthen the means of equipment testing and monitoring, shorten the period of equipment test and inspection, and ensure the reliable operation of electrical equipment. The analysis results can provide reference for similar projects.
