概述<br /> </strong></span>　　本产品为户外箱式组合互感器，适用于50HZ，6-10kV三相电力线路中作电流计量用，本产品是JLSGl—6.10改进型，由抗老化，憎水性、抗污闪性更强的硅胶套管，取代了付统老式的瓷套管。内部采用了高强度的环氧布管，大大的提高了套管强度和绝缘性能，使产品的可靠性、耐用性都得到了很大的提高。二次出现改为从箱内直接引出铠甲电缆，同其他类型的计量箱相比，具有优良的防窃电能力及运行的可靠性。<br /> 有以下优点：<br /> 　　1、一次出线由一瓶出线改为两瓶出线次盗电的可能。距离较远(大于200mm)，解决了<br /> 　　2、二次铠甲电缆直接从计量箱内引出，与电表箱接，解决了二次盗电的可能。<br /> 　　3、三元件计量箱(A、B、C)三相均装有电压电流互感器，消除了失压窃电的机会。<br /> <br /> <table border="0" cellspacing="1"

border="0" alt="" src="../pictures/product/201342314533441.jpg" /></td> <td>1、安装场所：户外。<br /> 2、环境温度”-40℃至+70℃<br /> 3、海拔：海拔高度不超过2000米<br /> 4、无腐蚀性气体。</td> </tr> </tbody> </table> <br /> <span style="color: #ff6600"><strong>运行可靠<br /> </strong></span>1、由于内芯采用硅橡胶浇注，其抗短路能力显著提高。<br /> 2、无油化、免维护设计。<br /> 3、抗过压、抗污闪能力强，憎水特性好。<br /> 　　由于该类设备一般安装在户外，承受各种过电压的机会远远大于户内产品，从产品的实际情况出发，其感应耐压水平，由原来2倍提高到4倍，一次出线瓷套改为硅橡胶制造，使其具有优良的抗污闪能力和抗过电压能力。<br /> <br /> <span style="color: #ff6600"><strong>结构特点<br /> </strong></span>　　该产品内部电压、电流互感器采用抗高寒耐高温的硅胶、电压互感器采用抗过电压设计，环氧布硅胶套管与箱体相接部分为丝扣式密封连接，使其更适宜在户外使用。两元件型，A、C两相有电压、电流互感器，三元件型，A、B、C三相均有互感器，可防止失压盗电现象。<br /> <br /> <span style="color: #ff6600"><strong>技术参数<br />
