Keyword:  整流变压器故障整流供电系统分析诊断;
Abstract: 调压整流变压器是铝电解供电系统中核心设备之一.变压器的正常运行是对铝电解整流供电系统安全、可靠、平稳运行的重要保证.由于铝电解供电系统长期不间断运行的负荷性质,整流变压器长期运行,设备在安装、检修、维护中存在的问题和制造过程中遗留的设备缺陷等事故隐患,特别是整流变压器长期运行后造成的绝缘老化、材质劣化及预期寿命的影响,已成为发生故障的主要因素,故障和事故不可能完全避免,且引发故障和事故又出于众多方面的原因.本文对铝电解行业整流供电系统调压整流变压器在运行中常见的短路、放电、绝缘故障类型进行了分析,并提出了判断依据和改进措施.
