电力变压器无线温度监测系统的研究

我国变配电用变压器数量众多、分布广泛,充分利用现有的无线电通讯技术、以太网等监测技术、可以构建一个安全可靠的变压器无线温度监测网。本文介绍了在配电变压器上安装无线温度监测系统,通过实时监测变压器的温度变化情况,及时发现变压器存在的缺陷或发生故障的位置,并通过中短距离无线网络转发方式,将信号传递至以太网,彻底解决现场监测配电变压器参数的困难,从而实现变压器数据的实时采集和传输,实现区域内乃至全国性的变配电变压器信息的汇集与监测体系。

Study on wireless temperature monitoring system of power transformer

The transformer for electricity transformation and distribution has a great quantity and has been widely used in China.By fully applying the existing monitoring technologies like radio communication and Ethernet,a safe and reliable wireless temperature monitoring network of transformer can be established.In this paper,the installation of wireless temperature monitoring system on transformer for power distribution was introduced.By monitoring the temperature variations in real time,it could find the existing defects or error position of transformer in time,and by the forwarding way of wireless communication in medium and short distance,the signals can be transferred to the Ethernet.It can solve the difficulty on field monitoring of transformer parameters,so as to realize the real-time collection and transmission,and establish the regional and nationwide influx and monitor system of information of transformer for electricity transformation and distribution.
