DAEYEON轉(zhuǎn)換器;DY-FFC-ACAY DY-FFC-ACNY要直接制作高壓儀表,直接在高壓線路上測(cè)量電壓,那是不可能的,而且也是不允許的。主要類型編輯按安裝可分為戶內(nèi)式和戶外式[4]35kV及以下多制成戶內(nèi)式;35kV以上則制成戶外式。按相數(shù)可分為單相和三相式35kV及以上不能制成三相式。按繞組數(shù)目可分為雙繞組和三繞組電壓互感器,三繞組電壓互感器除一次側(cè)和基本二次側(cè)外,還有一組輔助二次側(cè),供接地保護(hù)用。按絕緣可分為干式、澆注式、油浸式和充氣式[1]。干式電壓互感器結(jié)構(gòu)簡(jiǎn)單、無(wú)著火和危險(xiǎn),但絕緣強(qiáng)度較低,只適用于6kV以下的戶內(nèi)式裝置;澆注式電壓互感器結(jié)構(gòu)緊湊、方便,適用于3kV~35kV戶內(nèi)式配電裝置;油浸式電壓互感器絕緣性能。
