FAQ

C0/C1/C2 de qubie? (IEEE C37.06)
IEEE C37.06 genju rongdianqi yinhang qiehuan shi de OUTRUSH dianliu nengli dui kaiguan shebei jinxing fenlei. C0 (biaozhun): I_o < min(50kA, 1.41 x I_sc). C1/C2: I_o < 2.6 x I_sc, >=15% jingyu. C0 shi zai wu zhizaoshan wenjian shi de mohren zhijie.
bimainqi ruhe baohu TOV shijian?
MOV bimainqi (jinshu yanghua wumian bianzu) tongguo jiang langchong nengliang xie dao dimian lai xianzhi TOV. MCOV shi bimainqi keneng lianxu chengshou de RMS dianya; ta bixu chaoguo xitong dianya bing you jingyu. TOV nengliang (kV) biaoming bimainqi zai weiding de shijian neinei buneng shibai de chengshou de guodianya shuiing.
heshi luequ rongdianqi yinhang qiehuan shijian?
dang xuanze 'wu rongdianqi yinhang' shi, rongdianqi yinhang qiehuan bufen (yonglu, zhong jichuan, tongdian TOV) hui zidong luequ. shengyu de jiancha (MCOV/TOV, duanluqi duankai nengliang, 1LG guzhang, liuchu) zongshi yunxing.
dang TLI jianyi bei fuzha时报 zenyang?
TLI biaoji biaoshi liuchu dianliu chaoguo le duanluqi leibie de eding zhi. cuoshi: (1) yanzheng shangyou bianyaqi zuyang, (2) tianjia dianliu xianzhi diankangqi, (3) jiang rongdianqi yinhang yidong dao juyou genggao xitong zuyang de weizhi, (4) jiang duanluqi shengji dao gengao leibie (C1/C2).
