室外油浸变压器火灾事故分析与预防措施研究

本文主要以室外油浸变压器为研究对象,仔细分析了油变着火的主要原因和关键因素,并按照国家标准和电力设计手册的相关要求、规定,从继电保护、贮油或挡油设施、防火间距及防火墙的设置、防雷接地措施、灭火措施、维护保养等几个方面对油变着火的对策设施进行全面设计,设计的对策设施在一定程度上可有效地预防油变着火、燃烧甚至爆炸事故的发生,为油变的安全运行提供依据和参考。

For the the Oil-immersed transformers as the research object, analysis of the oil becomes the main cause of fire and key factors, analyzed the Oil-immersed transformers of main causes and key factors, and according to the rtational standards and the power design manual of the provisions,from relay protection, oil storage or oil retaining facilities, fire distance and firewall setting, lightning protection grounding measures, fire extinguishing measures and maintenance and many more to design countermeasures, countermeasure facilities can effectively prevent the Oil-immersed transformers fire, burning or even explosion accident, for the safe operation of Oil.immersed transformers to provide the basis and reference.
