采用工频通信技术的低压用户相线识别装置

采用“拉闸验电”的方法确定用户的变压器台区和相线属性存在很多弊端。在不中断对用户供电的情况下．直接对电网任意点进行丁线检测．经采集数据和自动分析．作出被检测点相线属性的识别，可为配电网管理提供必要的基础数据．对电力工频通信的信息通道与相线识别装置的技术实现进行了重点讨论．该装置能方便快捷地识别出用户或用电设备在电网中的电气属性．具有较高的经济效益和社会效益。

Low voltage user phase line identification device of work frequency communication technology

It has many evils that adopt witching off to test electricity method to assure property. Phase-line property, which is obtained by direct phase line measurement of arbitrary position without interruption of power supply for user and automatic analysis, can supply necessary basic data for scientifically managing electric power transmission networks. The recognition equipment of phase-line with power frequency communication technique is designed. System structure and features of the equipment are introduced. How to make information channel for power frequency communication and recognition equipment of phase line is discussed. The equipment can quickly identify electric property of power use device.And it has great social and economic benefits.
