摘要
根据GB 11032-2000等效于IEC 60099-4:1991《交流无间隙金属氧化物避雷器》,讨论10~500 kV站用无间隙金属氧化物避雷器(以下简称MOA)的额定电压(UR)、持续运行电压(UC)的选择,并通过保护水平与绝缘配合的比较,提出在工程设计中如何按新标准选择MOA的参数。
According to GB11032-2000,eqnivalent to IEC60099-4,1999"The AC Gapless Melatoxide Arrester",the selection of their rating voltage(UR) and continuous operating voltage(UC) for 10~500 kV substation used gapless metaloxide arrester(shorter form MDA) were discussed,and through the camparison between protection level and coordinated insulation,how to select the MOA parameter in accordance with the new standard in project design was put forward.
