4、与国类产品相比,体积小、重量轻、容量大、精度高、*合电控设计紧凑化趋向的要求。
5、*、阻燃、表面无一处带电,客体由*阻燃材料高压注塑成型,强度高且不燃烧。
6、坚固、耐用、整个产品为全封闭型、有耐温、*潮、*振、*污、*盐雾、*窃电等特点。
Series BH,MSQ,SDH current transformer is mainly used for power system with rated frequency 50Hz and rated voltage under 0.66KV to measure electric energy, current and protect relay.
1.With full complete of specification and wide range of application, suitable for any primary current range from 5A to 5000A or from 1A to 4000A(including non-standard specificaiton),the secondary current has two t*es:5A and 1A, the different window t*es can match with different bus-bars and cables.
2.With nice appearance and reasonable design.
3.With advanced technology and excellent performance.
4.Compared to same line of products, this product is more compact, less weight, larger capacity, higher accuracy and more compliance with the standard of electric-control design.
5.With feature such as safety, flame retardant, without static electricity in the surface, the case is made of imported flame retardant material by high-pressure casting, so it has feature of high strength and resisting flame.
6.With features of firmness, durability, full-seal , high temperature resistant, moisture proof, shock proof, anti-salt spray and prevent from electric-theft.

Model description for BH, MSQ and SDH current transformer :
L-current transformer; K-plastic case; M-bus t*e; 1 or 2-design S/N;
A/B cl*ification:
1.A: for square or circular t*e, can go through cable or busbar, generally used for monitoring.
2.B: for horizontal square-hole t*e, can go through 1 to 3 busbar,generally used for monitoring.

 

 
使用范围 Application scope
1.工作电压≤0.66kV;
2.额定频率50~60Hz;
3.海拔高度不*过1000m;
4.周围介质温度为-5℃~ 40℃
5.空气相对温度不*过85%;
6.用于没有雨雪直接侵袭,无严重污染,无*无剧烈震动、无腐蚀金属和破坏*缘额尘埃或蒸汽的场所。
1.working voltage: ≤0.66kV;
2.rated frequency: 50~60Hz
3.altitude≤1000m;
4.amboent temperature: -5℃~ 40℃
5.RH: ≤85%;
6.environment without rain or snow, no heavy pollutat, no explpsion or shock, no corrosive metal or dust or steam.
 
使用方法 Usage
1.根据一次电流及母线截面等参数选取对应的规格。一次导线(一次线圈)穿越*窗孔,卸下*顶部接线罩壳,支掉引线垫片,二次线引出后罩壳复位,计量电能用的可利用固定螺丝和罩壳上小孔加封铅印,以*窃电。
2.产品*性表示,P1表示一次线圈的*性端,S1表示P1的同名端,S2表示P2的同名端。
1. Select the suitable specification according to primary current and section of bus. The primary windings go through the window-hple of *, di*antle the cover on the * of * and remove shim, the cover will reture to its original position after the secondary windings lead out, use screw to fix it and seal with lead inside the hole of case to prevent from electric-theft.
2.Polarity: P1 indicates the ploarity of primary winding. S1 indicates the same polartiy of P1, S2 indicated the same polarity of P2.
 
注意事项 Note
1.互感器允许接到不*过0.66kV的交流电路中,长期工作电流不*过额定值的1.1倍,允许1.2倍额定电流的短时间使用,背景时间不*过1小时,瞬时(1S内)工作电流不允许*过60倍额定电流(30B型为40倍)非标和作保护用的例外。
2.测试仪表接于S1,S2端子上,此时*须注意所接仪表的总阻*(包括接线)不*过互感器的额定负荷。
3.互感器在运行中严禁二次开路,加入二次线圈以外在通电时发生开路,则*须进行退磁处理,以减少误差的增加。
1. The transformer is used for AC circuit with rated voltage under 0.66KV, the working current should not exceed 1.1 times of rated current in long-term use of this product; for short-time use(e.g., Beijing time less than 1 hour), the working current is permitted up to 1.2 times of rated current, the instantaneous(within ls)working current should not exceed 60 times of rated current (model 30B shall be 40 times of that)(excluding non-standard or any t*e use for protection)
2.The measuring meter should beconnected to terminal S1 and S2, and the overall impedance of the transformer(including connecting wire) should not exceed the rated load of transformet.
3.The secondary winding is strictly prevented secondary from open circuit during operation, If any open ciruit occars accidentally for secondary winding, it musted be treat with demagnetizing process to reduce error during measurement.
