摘　　要：通过对繁昌变电所５００ ｋＶ 氧化锌避雷器的红外检测和部分避雷器的整体试验、解体试验、加速老化试验和内部残留物的Ｘ射线荧光光谱试验，分析了这批避雷器电气性能普遍下降的原因，为修复提供了依据，为仍在运行的同批次该型号避雷器的在线监测提供了经验。Through the infrared temperature detection and a series of arrester tests, including general assemble test, disassemble test, accelerated aging test of resistor and X ray spectrum analysis of internal residue for 500 kV zinc oxide surge arrestor in Fanchang Substation, the cause for general performance declining of this batch of arresters is analysed, which provides basis for repairing and experience for on line monitoring of the same model operating arresters.
