style="color: #ff6600"><strong>概述<br /> </strong></span>　　JLGYK<sub>2</sub>-0.5W 低压带真空开关预付费计量箱适用于交流50Hz、0.38kV三相电力系统中做户内(户外)预付费计量或负控使用，由低压真空开关及计量用交流互感器、预付费电表及远控终端(用户有要求时安装)构成。低压真空开关为永磁结构，合分闸后，合闸分闸线圈不带电，避免分合闸线圈长期带电易烧毁的现象，其灭弧装置采用真空管，具有无重燃、使用寿命长等特点。</div> 　　本产品采用不锈钢外壳，重量轻，结构紧凑，可在户内安装(壁挂式)，也可在用户使用，结构简单，施工方便，具有预付费控制、抄表、电能参数采集、反窃电等功能。<br /> <br /> <span style="color: #ff6600"><strong>型号定义 <div style="text-align: center"><img border="0" alt="" src="../pictures/product/20134198164620.jpg" /><br /> </div> <br /> 产品特点 </strong></span><br /> 　　●本产品采用不锈钢壳体，分电表计量室及开关室，两室之间有隔板，双门结构，开关室装有预付费电能表及远控终端，用于电能计量及远方控制，开关室内装有02.S级电流互感器及低压真空负荷开关，电表又费时开关可以手动或电动操作，无费自锁，并设用非法开启箱门断电报警装置，门锁采用磁性密码锁，具有良好的防窃电功能，预付费控制分为就地及远方型。<br /> 　　●就地型：用户计量采用IC卡预付费电表，有费供电，无费报警后断电，报警电量用户可以设定，报警可采用蜂鸣、震铃或语言形式，当用户重新购买电量后，刷卡，可重新解锁、合闸供电。<br /> <strong>　　●</strong>远传型：用户可采用普通电子式电表，预付费控制由GSM—SM预付费控制系统完成，该系统采用手机短信的通信方式，同时可实现计量点的预付费控制、电力参数实时监控、剩余电量提示报警、远程抄表、欠费拉闸断电、自动生成报表等功能。<br /> 　　●用户预交电费后，由后台计算机(管理手机)下发至前置机，前置机判断后合闸送电，当电量达到预付费电量设定的报警值时，前置机向后台计算机报警，计算机将报警信息以手机短信的形式转发给3部设定手机，无费后系统自动断电。<br /> <br /> <span style="color: #ff6600"><strong>主要技术参数<br /> </strong></span> <div
