对电力行业标准《交流输电线路用复合外套金属氧化物避雷器》(草稿)的建议—关于带串联间隙交流用复合外套MOA的动作负载试验方法

A Proposal to the Electric Power Industry Standard:Polymeric Housed Metal Oxide Surge Arrester for a.c.Transmission Line(draft)-Test method of duty test for gapped polymeric housed MOA

对电力行业标准《交流输电线路用复合外套避雷器》 (草稿 )中的带串联间隙的线路用复合避雷器本体的动作负载试验方法进行了分析 ,指出了其不足之处 ,并提出一种新的试验方法的建议 ,与日本同类试验方法比较 ,该方法考虑了冲击电流对金属氧化物电阻片的小电流伏安特性的影响。

Analysis has been made for electric power industry standard'Polymeric Housed Metal Oxide surge Arresters for a c transmission line'(draft)in respect to duty test of gapped polymeric housed metal oxide surge arrester,it′s disadvantages have been pointed out.A new test method has been proposed with consideration of effect of surge current on volt ampere characteristics of metal oxide resistors at small current region in comparison with the Japanese method.
