Electrical equipment installed on the high-voltage side of high-voltage transmission lines

Currently, the most widely used power supply method is solar power supply, but this method is greatly affected by climate conditions and lacks long-term maintenance-free capabilities. Laser power supplies have been used in electronic current transformers and active optical current transformers, but this type of power supply is not suitable for field work. A more promising power supply method is to extract electric energy from overhead transmission lines, place an energy coil on the line, and convert the energy of the line to the secondary side to achieve isolated power supply.

Power equipment installed on the high-voltage side of high-voltage transmission lines: conductor temperature, breeze vibration, secondary pitch oscillation tension, ice coating monitoring device, etc. of high-voltage overhead transmission lines.

Power equipment that is difficult to obtain power near high-voltage transmission lines: various monitoring equipment on underground power cable lines, monitoring equipment in ring main units, etc.

Performance characteristics:

Induction energy harvesting, stable and safe, maintenance-free

Open energy harvesting transformer, easy to install and simple to wire.

The energy harvesting module is packaged with metal shielding, which has good sealing performance, adapts to harsh environments, and operates stably. Able to maintain stable output despite changes in line current. Adopts switching voltage stabilization standard design. The output voltage is stable and the ripple is small. The output power can reach more than 300W

Can work continuously under 3000A current

Can be installed on transmission lines with any voltage level from 6kV to 500kV. The battery pack is optional to maintain normal use during power outages.

Working principles:

The energy harvesting device of the transmission line consists of an energy harvesting transformer and an energy harvesting power module.
