一起干式铁心电抗器烧毁事故分析及防范措施探讨

Analysis and Prevention Measures of a Dry Iron Core Reactor Burning Accident

目前,电抗器对电力系统的安全可靠运行起着重要作用。铁心电抗器因具有体积小、损耗低、易安装和维护等优点,广泛应用于电力系统。以一起10kV干式铁心电抗器烧毁事故为背景,结合事故发生过程、后台数据、事故发生后现场信息和烧毁主体返厂解剖分析等信息,采用逆向推理方法,综合分析了此次事故发生的缘由,并提出了杜绝此类事故再次发生的若干建议。

At present,reactor plays an important role in the safe and reliable operation of power system.Core reactor is widely used in power system because of its small size,low loss,easy installation and maintenance.Taking a 10 kV dry core reactor burning accident as the background,combined with the accident process,background data,site information after the accident and the anatomical analysis of the burned main body returning to the factory,this paper comprehensively analyzed the causes of the accident,and put forward some suggestions to prevent the recurrence of such accidents.
