一种新型电能表电压取样端头的应用

Application of a New Voltage Sampling End for Electric Energy Meter

介绍了一种电压取样端头,巧妙地利用了联合接线盒电压搭片中间开槽的特殊结构,改变了传统鳄鱼夹型电压取样端头的结构形式,解决了使用时夹紧度不够和金属部分裸露过多的缺点,在电能表现场校验时消除了获取电压时产生二次回路相间短路的安全隐患,减小了误碰其他带电设备的几率,提高了现场校验工作的安全性。

The paper introduces a voltage sampling end. The new voltage sampling end dexterously uses open slot in the middle of voltage bonding jumper of combined terminal box and changes the traditional alligator clip type voltage sampling end, having terminated the disadvantages such as contract looseness during the use and over-exposedness of metal part; eliminated the potential hazard of inter-phase short circuit of secondary circuit in the process of voltage extraction during onsite calibration of electric energy meter; decreased the probability of false touch on other live equipment and improved the security of onsite calibration.
