Fixedly installed current abnormality monitoring device: This device is fixedly installed on the line. It needs to be connected to 220V mains power from the line to collect current data on the line, and then send the data to the concentrator through wireless networking, and then pass the concentrator. All data is sent to the master station, and it is judged whether there is electricity theft according to the abnormal current on the line.

2.人工巡视排查:人工对供电线路进行巡视,通过肉眼判断线路上是否存在私自接线行为,通过仪器仪表检测电表的计量装置是否存在问题,从而判断是否出现窃电现象。2. Manual inspection and inspection: manually inspect the power supply line, judge with the naked eye whether there is any unauthorized wiring on the line, and check whether there is a problem with the metering device through instruments and meters, so as to judge whether there is electricity theft.

b)安装过程工作量很大,而且必须要停电作业,影响供电可靠性。b) The workload of the installation process is very large, and power outages must be performed, which affects the reliability of power supply.

c)因为是被测线路的工作结点,设备一旦发生故障则会导致整条线路断电,再次影响供电可靠性。c) Because it is the working node of the line under test, once the equipment fails, it will cause the entire line to be powered off, which will affect the reliability of power supply again.

d)无独立的远程数据传输通道,必须依赖安装在配变侧的第三方设备把采集到的数据传输到后台主站。d) There is no independent remote data transmission channel, and it must rely on third-party equipment installed on the side of the distribution transformer to transmit the collected data to the background master station.

e)因为无法重复使用,导致整体投资成本增大。e) Because it cannot be reused, the overall investment cost increases.

2.人工巡视排查存在的问题和缺点:2. Problems and shortcomings of manual inspection:

a)人工肉眼排查,工作量大,投入人力成本高。a) Manual visual inspection requires heavy workload and high labor cost.

b)一般窃电行为的接线方式都是隐蔽的,在外人无法看到的地方接线,人工排查容易产生排查盲区。b) Generally, the wiring methods of stealing electricity are concealed, and the wiring is done in a place where outsiders cannot see, and manual investigation is likely to cause blind spots in the investigation.

c)一般窃电行为都是晚上在工作人员下班之后发生,白天恢复正常,增加了人工排查工作的复杂性。c) Generally, electricity theft occurs at night after the staff get off work, and returns to normal during the day, which increases the complexity of manual investigation.
