摘要
电力系统测量装置的自供电技术是根据电磁感应或者能量交换的原理,实现从电源到负载的无线供能的一种取电方式。与传统的有线方式相比,无需独立电源为设备供能,具有高度智能化、高可靠性等优点,尤其在一些特殊的场合,将会得到更广泛的应用。主要阐述现有的6种主流自供电的实现方式,并对其工作原理、传输效率以及存在的问题进行分析;根据各类供电方式的研究现状,对今后自供电技术的发展趋势进行展望。
The self-powered technology of power system measurement device is based on the principle of electromagnetic induction or energy exchange,which realizes a way of power supply from power to load. Compared with the traditional wired way,no independent power supply is needed for the equipment,it has advantages of high intellectualization and high reliability,especially in some special occasions,so it will be more widely applied. The existing six kinds of mainstream self-powered implementation are discussed. The working principle,transmission efficiency and existing problems are analyzed respectively.Combining with the existing research situation of various power supply methods,the future development trend of self-powered technology is forecasted.
