電子式電流互感器
 
名稱:電子式電流互感器
型號:LEMZKJH8-0.5

LEMZKJH8-0.5型開合式電子式電流互感器
LEMZKJH8-10.5 open-close type electronic current transformer
一、概述(Description)
   本型開合式電子電流互感器主要適用于額定頻率50Hz或60Hz、額定電壓35kV及以下的電力系統(tǒng)中測量電流,廣泛用于緊湊型全絕緣環(huán)網(wǎng)開關(guān)柜,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 open-close type electronic current transformer is used for metering current in the electrical system up to rated frequency 50Hz or 60Hz and rated voltage 35kV. It is widely used for the compact all insulation ring net switch cabinets. The transformer can be executed according to the standards IEC60044-8:2002 and GB/T20840·8-2007。

三、結(jié)構(gòu)簡介(Construction)
本型電子式電流互感器為開合式,采用ABS工程塑料外殼環(huán)氧樹脂一體化澆注成形,具有絕緣性能好,外形美觀,便于安裝等特點。該產(chǎn)品體積小,重量輕,無需維護(hù),安裝時將兩個半圓環(huán)抱在分相電纜上,用抱箍抱緊卡住,與電纜于一體,和諧美觀。特別是其開合式結(jié)構(gòu)可直接卡裝在電纜上,實現(xiàn)在不改動電纜的情況下免工具安裝。測量范圍寬,二次開路不會產(chǎn)生高電壓,二次輸出為小電壓信號,功耗極小,不需將大信號轉(zhuǎn)化為小信號,簡化了誤差源,提高了整個系統(tǒng)的穩(wěn)定性和準(zhǔn)確度。
This type of electronic current transformer is the open-close type, uses ABS engineering plastic the shell and the forming of epoxide resin casting. It has the characteristics of excellent insulating performance, beautiful appearance and easy installation. This product has small volume and light weight and there is no need to repair it. During the process of installation, two semicircular rings hold the individual phase cable and are tightened by anchor ear. It forms one whole body with the cable, resulting in neat and beautiful appearance. Especially, the open-close structure can directly be clamped on the cable and realizes the tool-free installation under the condition that the cable is not changed. 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.)
