订货须知 Order notice

1、订购电流互感器时,请提供型号、额定电流比,准确级及准确线组合,额定输出、短时热电流、额定动稳定电流等参数,其中划线项目必需提供。例:LZZBJ9-10A1 600/505/10P1010/15VA

2、订购电压互感器时,请提供型号、频定电压比,准确级及准确级组合,额定输出,其中划线项目必需提供。

例:JDZ10-10AJ1001KV0.2级30VA

3、订购低压互感器时,请提供型号,额定电流或电压比,如订购塑壳式互感器,请提供穿排尺寸。例:LMK3-0.66140400.5

4、营规产品的使用条件为:环境温度-5℃-+40℃,海拔高度为1000m以下,若产品使用地点的温度和海拔高度超出以上范围时,请在订货时注明,以便按要求生产和供货

1、Please supply the modet number, normal current transformation ratio, degree of accuracy or these compounding normal input, instant thermoelectrie current, normal dynamic stabillty current when ordor the current transducerOf these some toms lined are essential. eg:LZZBJ9-10A1 600/50.5/10P10 10/15VA

2、Please supply the model number, normal voltage transformation ratio, degree ot accuracy. normal input when order tho voltage transducer of these some ites lined are essential eg:JDZ10-10AJ 10/01KV 0.2级 30VA

3、.Plense supply the model numbernormal curent transformation ratio and supoly the size of interpenetration i it is tplastic she when order the low voltage transducer.Of these some fems lined are essontial

eg:LMK3-0.66/40 400/5

4、Transformers conditions amblent air temperature-5℃-+40℃ and altitude above sea-level: under 1000mit the ambient air temperature and altitude above ses-level are different from the condition,be sure to declare cleary in the contract. So the factory will produce and deliver products according to requirement form customers.

 

通用说明书

1、电流互感器型号字母含义Type descniption of current transformer

 

2、电压互感器型号字母含义Type description of voltage transformer

 

3、电流互感器一次有电流流过时,二次绕组禁止开路,否则二次将有高压产生,危及人身及设备安全。

The secondary Winding of the current tranducer must be forbidden to open when curent passes through the priary winding.ortherwise the safety both of the person and of the apparatus will not be guntanteod

4、电压互感器工作时,二次严禁短路,否则互感器将被烧毁。

Forbide a short circuit on the secondary winding when the voltage transducer is operating, otherwsw overburing will happon.

5、接地电压互感器使用时,应配置消谐装置,以防止铁磁谐振对互感器的损害。

Provide the ant-resonance dovice for the grounding voltage transducer so as to roduce the damago of the ferromagnetic resonance.

6、接地电压互感器,考核一次绝缘时,应采用感应耐压试验,开关柜整体试验时,应将此类互感器的一次接线断开。

Apply the induced over voltage withstand test when chect the primary winding insulation of the grounding voltage transducer.Since each transducer has been tested before out of the factory, the test can be left out

7、用户对互感器进行工频及感应耐压复试时,应按规定在出厂试验电压的80%下进行。

When retest instant power frequency withstand voitnge,please operate below 80 percent of the stated testing voltage.

8、产品不断改进,更新,多数可能发生变化,恕不另行通知,可与公司即时沟通。

The company products are updated upgraded,the techinica parameter may change, forgive me for not issuing a soparate notice,please communicate get in touch wwith our cpmpany in tme
