Vibrational De-icing Technology for Power Transmission Lines: An Innovative Approach

This paper focuses on the development of an online transmission line de-icing device that integrates energy harvesting, monitoring, and de-icing technologies. The device comprises a vibration generation module, an environmental monitoring module, and an energy harvesting module. The vibration generation module produces specific frequency vibrations to stimulate the vibrations of ice-covered conductors, while the environmental monitoring module adjusts the mode and frequency of vibration to optimize the de-icing effect. The device's energy supply comes from the static electric field generated by the transmission line, known as electrostatic energy harvesting. The main advantage of this electrostatic energy harvesting method is its self-sufficiency, independence from external power sources, reduced maintenance costs, and environmentally friendly energy collection. The vibrational de-icing method involves installing vibration devices directly on the conductors to disrupt the adhesion between ice and the conductor surface, create internal cracks, and enhance the de-icing effect through resonance. The technology and device proposed in this study show significant advantages in terms of safety, efficiency, and environmental adaptability, and are expected to see broader application in the future.
