产品详细介绍
品牌 | 华能 | 型号 | LZZBJ12-10 |
产品认证 | ISO9001:2000 |
一、概述(description)
本型电流互感器为环氧树脂浇注绝缘全封闭式产品,适用于额定频率50hz或60hz、额定电压10kv及以下的户内电力线路及设备中作电流、电能测量和继电保护用。本型电流互感器体积小、重量轻、绝缘性能优越、精度高、动热稳定倍数高。产品符合iec44-1:1996及gb1208-1997《电流互感器》标准。
the current transformer of the type lzzbj12-10 is casting
resin and fully enclosed indoor product. it is used for metering
current and electric energy, relay protection in the electrical
system of rated frequency 50hz or 60hz and rated voltage 10kv. the
current transformer has the character of small volume, light
weight, superior insulation, high accuracy, high dynamic multiple
and so on. the transformer can be executed according to the
standards iec44-1:1998 and gb1208-1997《current transformer》.
三、结构简介(construction)
本型电流互感器为全封闭结构,一、二次绕组及铁芯均浇注在环氧树脂内,耐污染及潮湿。
the current transformer is fully enclosed. the primary and
secondary windings and iron core are insulated by epoxy resin. it
has a good ability of antipollution and moisture proof.
四、技术参数(technical data)
1. 额定绝缘水平:12/42/75 kv。(rated insulation level 12 / 42 / 75
kv.)
2. 额定频率:50hz 、60hz。(rated frequency 50hz or 60hz.)
3. 额定二次电流:5a 、1a。(rated secondary current 5a or 1a.)
4. 局部放电水平符合gb1208-1997《电流互感器》标准。(the conditions of the partial
discharge test are in accord with the standard gb1208-1997《current
transformer》with be fulfilled without exception.)
5. 可以制造计量用0.2s或0.5s级高精度电流互感器。(we can make high precision
current transformer of class 0.2s or 0.5s for measuring).
6. 额定一次电流、准确级组合、额定输出及额定动、热稳定电流见表1-3。如用户无详细说明,
本公司按常规技术参数供货。(rated primary current, accuracy combination,
rated output, rated dynamic and thermal current see form 1-3. if no
define, we will make product according to the general technical
data.)
