Problems solved by technology
It is difficult to obtain power from the ground for long-term electronic monitoring and indicating equipment. The battery power supply method often used will be exhausted in a short period of time, and replacement is extremely inconvenient or even impossible. As a result, electronic monitoring and indicating that the device is not working
The inductive energy harvesting power supply that requires the transmission line to pass directly through the center cannot be applied to the installed medium and high voltage transmission lines, while the induction energy harvesting power supply installed with openings is bulky and heavy, and is not suitable for medium and high voltage transmission lines

Embodiment Construction
[0014] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0015] Such as figure 1 As shown, the clip-on power supply of the present invention includes two clip-on connectors 2 , a conductor 3 and an induction energy collector 4 . One end of the clip-on connector 2 is connected to the transmission line 1, clamped and fixed, and the other ends of the two clip-on connectors are connected through a conductor 3, and the conductor 3 passes through the coil wound in the induction energy harvester device 4. magnetizer.
[0016] Such as figure 2 As shown, the output of the coil-wound magnetic conductor 5 is connected to the rectifier circuit 6, and the output of the rectifier circuit is connected to the holding circuit 7, and the output of the holding circuit 7 is the DC output voltage of the clip-on power supply. The clamp connector 2 is electrically connected to the tr...

The invention discloses a clamping power supply, which belongs to the technical field of power supply. For development, overhead medium-high voltage transmission line (including under river cable) is provided with electronic monitoring and instructing equipment, but the power supply of the equipment cannot be obtained from the ground due to high insulation requirements. In the conventional battery power supply mode, energy runs out in a short time period. The clamping power supply comprises a clamping connector connected with the transmission line, a wire and an inductive power extraction device, wherein the inductive power extraction device comprises a magnetizer wounded with a coil, a rectifying circuit and a holding circuit. The power supply can extract power from the transmission lineto supply the power to the electronic monitoring and instructing equipment.
Description
technical field [0001] The invention belongs to the technical field of power supplies, and in particular relates to an energy harvesting power supply suitable for power grid transmission lines. Background technique [0002] With the rapid development of electric power transmission, there are more and more high-voltage overhead transmission lines (including cross-river cables). With the popularization of smart grids, various electronic monitoring equipment will be equipped on medium and high voltage transmission lines, and some areas in mountainous areas, foggy areas and dark nights need to be instructed to avoid danger. It is difficult to obtain power from the ground for long-term electronic monitoring and indicating equipment. The power supply energy of the commonly used battery power supply will be exhausted in a relatively short period of time, and replacement is extremely inconvenient, or even impossible. As a result, electronic monitoring and The indicating device is n...
