现场用电检查人员面临的实际困难:目前主要采用人工的方式进行检查,包括核查拆箱、拆电能表等方法,不仅工作量大,且容易造成用户强烈反对,现场工作难度较大。
目前计量箱防窃电功能不足,存在的主要问题是:窃电手段从由较原始的方式,如私拉乱接无表用电、绕越电能表用电、伪造铅封、私自开启电能表接线盒封印和电能表表盖封印用电、损坏电能表及计量互感器用电、10kv搭接窃电方式窃电等,已发展到现代化高技术含量的智能型窃电方式,如使用倒表器窃电、使用移相方式窃电、使用有线或无线遥控方式窃电、利用强磁场、高压放电窃电以及安装“节电器”窃电等。上述窃电方式技术含量明显提高,窃电时机灵活,窃电查处及取证极为困难,因此需要发明一种防窃电远程智能监控方法。
