| 摘要: |
| 利用导地互感公式推导了不同相线电流情况下地线损耗功率，在此基础上提出了一种可应用于分段地线网络的地线取能方法，并基于所提方法设计了取能设备。该取电装置具有输入动态范围大、转换效率高、抗干扰能力强的特点。在导线负荷满足要求的情况下该装置可以替代光伏电源实现对在线监测设备的稳定供电。 |

| Abstract: |
| The loss power of ground wires under different phase currents is deduced using the mutual inductance formula, based on which, a method of extracting power from the overhead ground wires is proposed for the sectionalized ground wire network. A power extraction equipment is designed based on the proposed method. The equipment has the characteristics of large input dynamic range, high conversion efficiency and strong anti-interference ability. When the wire load meets the requirements, the power extraction equipment can replace the photovoltaic power supply to realize stable power supply for on-line monitoring equipment. |
