摘要
通过对沙角A电厂沙鹏甲线线路阻波器设备内的无间隙氧化锌(ZnO)避雷器爆炸原因的分析,说明对ZnO避雷器实行在线监测的意义。在对各种金属氧化物避雷器在线监测方法进行比较和实例分析的基础上,指出红外测温在线监测和高压预防性试验相结合是值得推广和应用的ZnO避雷器运行监测方式。
Upon causal investigation into the explosion of gapless ZnO arrester in the trap of Shapeng Line A from Shajiao A Power Station, the significance of on-line monitoring on ZnO arrester is indicated. Based on comparison and case analysis of various on-line monitoring means for metal-oxide arrester, the combination of on-line monitoring with infrared temperature measurement and HV preventive testing is recommended for operation monitoring of ZnO arrester.
