Example Embodiment
[0033] A CT-based power acquisition device for overhead lightning protection ground wires of power transmission lines includes a power-taking iron core connected to an overvoltage protection unit, and the overvoltage protection unit is connected to a power supply stabilizing unit, The power monitoring unit is connected to the output terminal of the overvoltage protection unit.
[0034] The overvoltage protection unit, the connection of the power supply voltage stabilizing unit and the power supply monitoring unit constitute the power supply device.
[0035] The power take-off iron core L1 has a ring design, which includes two upper and lower iron cores. The upper and lower iron cores are aligned during installation to enclose the overhead ground wire (see figure 1 ), a coupling coil is wound on the toroidal core, and both ends of the coupling coil are the output terminals of the power core.
[0036] There is a PVC outer casing outside the power-taking iron core L1, and epoxy resin po...
