LEMZBJH8-0.5型電子式電流互感器
LEMZBJH8-0.5 electronic current transformer
一、概述(Description)
本型電子式電流互感器為澆注絕緣戶內(nèi)裝置，適用于額定頻率50Hz或60Hz、額定電壓為10kV及以下的電力系統(tǒng)中穿單芯絕緣電纜時(shí)作繼電保護(hù)用。本產(chǎn)品符合IEC60044-8：2002及GB/T20840·8-2007《電子式電流互感器》標(biāo)準(zhǔn)。
The electronic current transformer is casting resin insulated and used indoors. It is used for relay protection in the electrical system with single-core cable up to rated frequency 50Hz or 60Hz and rated voltage 10kV. The transformer can be executed according to the standards IEC60044-8：2002 and GB/T20840·8-2007

三、結(jié)構(gòu)簡(jiǎn)介(Construction)
本型電子式電流互感器為母線式，環(huán)氧樹脂澆注結(jié)構(gòu)�；ジ衅鞅旧頍o(wú)一次繞組，單芯絕緣穿過(guò)互感器內(nèi)孔即為互感器一次繞組。電纜測(cè)量范圍寬，二次開路不會(huì)產(chǎn)生高電壓，二次輸出為小電壓信號(hào)，功耗極小，不需將大信號(hào)轉(zhuǎn)化為小信號(hào)，簡(jiǎn)化了誤差源，提高了整個(gè)系統(tǒng)的穩(wěn)定性和準(zhǔn)確度。
This electronic current transformer is busbar type and casting resin insulated. It has no primary winding. The single-core cable through it is as the primary winding. This transformer has wide measurement scope, the secondary open circuit does not produce high voltage and the secondary output is the signal of low voltage. The power consumption is very small. As there is no need to transfer the signal of high voltage to the signal of low voltage, the source of error is simplified and the stability and order of accuracy of the whole system are improved.
四、技術(shù)參數(shù)(Technical data)
1、本型電子式電流互感器的一次主絕緣由電纜保證，產(chǎn)品僅考核二次繞組的絕緣性能。二次繞組對(duì)地能承受3kV工頻耐壓。(Because the cable protects the primary main insulation, so, the insulation characteristics of secondary winding are only examined. The secondary winding can be able to withstand the power frequency test voltage of 3kV to ground.)
