電子式電流互感器
 
名稱:電子式電流互感器
型號(hào):LEZZJH8-10W1

LEZZJH8-10W1電子式電流互感器
LEZZJH8-10W1 electronic current transformer
一、概述(Description)
本型電子式電流互感器為環(huán)氧樹脂澆注絕緣全封閉支柱式產(chǎn)品,適用于額定頻率50Hz或60Hz、額定電壓10kV的電力系統(tǒng)中,作電能計(jì)量、電流測(cè)量和繼電保護(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, fully enclosed and post type product. It is used for metering electric energy and current, relay protection in the electrical system 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環(huán)氧樹脂澆注絕緣全封閉支柱式結(jié)構(gòu),耐污染及潮濕,適宜于任何位置、任意方向安裝。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 casting resin insulated, fully enclosed and post type product. It is fouling resistance and moisture protection, and can be erected at any position and direction. 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、額定絕緣水平(rated insulation level):12/42/75kV
2、局部放電水平符合GB/T20840·8-2007《電子式電流互感器》標(biāo)準(zhǔn)。(The conditions of the partial discharge test according to GB/T20840·8-2007《electronic current transformer》will be fulfilled without exception.)
3、此互感器二次繞組只能生產(chǎn)單繞組。(The secondary windings of this transformer can only produce single winding.)
