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

A power supply based on mutual inductance for conductor monitoring sensor was designed by making use of the principle of mutual inductance

in which the electric power in the conductor at high-voltage side is inducted to secondary low-voltage side through induction coil

and is then rectified

filtered

voltage-stabilized

and DC-DC processed for online monitoring device. To deal with the problems of transient current

insufficient current

and excessive current in conductor

the transient over-voltage protection

the over-voltage/over-current protection

and the protection for lithium-ion batteries were adopted

respectively. The over-voltage/over-current protection is divided into two levels

one is for the protection in the case of normal fluctuation of current wave

the other is for the protection in the case of abnormal over-current or short-circuit fault of transmission conductor. An experimental platform was constructed for testing the designed power supply. The conductor monitoring device equipped with the designed power supply was validated.
