摘　　要：特高压变电站的固定灭火系统完好是实现其灭火能力的重要前提。首先,通过对现有标准中消防管网耐火能力试验方法进行对比,结合特高压变压器实体火灭火试验数据,明确了特高压变电站水喷雾灭火系统消防管网耐火能力现状。其次,利用气体燃烧器原理设计试验火源,测试结果显示试验火源温度与全尺寸特高压变压器实体火灭火试验中测到的温度较一致,利用该试验火源开展试验能符合实际工况。最后,通过对比试验给出了水喷雾消防管网耐火能力提升建议,为实际工程改造与建设提供参考。The integrity of the stock fixed extinguishing system of the UHV substation is an important prerequisite to realize its extinguishing ability.First,the fire resistance status of fire pipe network of water spray extinguishing system for the UHV substation is defined by comparing fire resistance test methods of fire pipe specified in existing standards and combining with true fire extinguishing test data of UHV transformer.Secondly,the principle of gas burner is used to design the test ignition source.The temperature of the test ignition source is in good agreement with the temperature measured in the fire extinguishing test of the full-size UHV transformer model.Therefore,using the test ignition source to carry out the fire resistant test can be more in line with the actual possible heating situation.Finally,through the comparative test,some suggestions to improve the fire resistance of water spray fire pipe network are proposed,which can provide reference for the actual engineering reconstruction and construction.
