发布时间：2018-10-16 12:26
【摘要】：笔者设计了基于互感取能的导线监测传感器电源,该电源利用互感原理,通过取能线圈将高压侧导线上的电能感应到二次低压侧,然后经过整流滤波处理、稳压处理和DC-DC处理后,供在线监测装置使用。基于以上原理做出了具体设计,并且为了应对导线上电流瞬变、电流过大和电流不足等问题,分别采取了加入瞬时过电压保护、过压过流保护和锂电池的措施,其中过压过流保护分为两级,一级针对导线电流正常波动时的保护,另一级针对输电导线异常过流或短路故障时的保护。并搭建实验平台进行测试,最后,用笔者所研制的一种基于该电源的监测装置对其进行了验证。
[Abstract]:Based on mutual inductance, the power supply of wire monitoring sensor is designed in this paper. By using mutual inductance principle, the electric energy on the high voltage side wire is induced to the secondary low voltage side by using the principle of mutual inductance, and then rectified and filtered. After steady voltage treatment and DC-DC processing, it can be used for on-line monitoring device. Based on the above principle, the concrete design is made, and in order to deal with the problems of transient current, excessive current and insufficient current on the wire, the measures of adding instantaneous overvoltage protection, over-voltage overcurrent protection and lithium battery are adopted, respectively. The overvoltage and overcurrent protection can be divided into two stages, one is the protection against the normal fluctuation of the conductor current, the other is the protection against the abnormal overcurrent or short-circuit fault of the transmission wire. An experimental platform was built to test it. Finally, a monitoring device based on the power supply was developed to verify it.
