Design and experimental study of CW laser cleaning system for high voltage transmission lines ice-covered

Icing of high voltage transmission lines is an important factor affecting the normal operation of power grid.Laser deicing has a broad application prospect in high voltage transmission line deicing because of its excellent performance.In order to cleaning the high voltage transmission lines ice safety and quickly,the theory of laser cleaning ice is analyzed and studied.The system of laser cleaning ice for high voltage transmission lines is designed based on CW laser.The experiment device is established.The effects of melting ice at different distances and at different power were studied experimentally.The results show that the effect of laser deicing depends largely on laser parameters.When the laser power and distance are the same,the depth of ice melting hole increases with the power.With the same laser power,the melting hole depth decreases with increasing distance.When the laser spot diameter is small and the power is large,the melting ice aperture is slightly smaller than the spot diameter.When the laser spot diameter is larger and the power is smaller,the melting ice aperture is larger than the spot diameter.The system is simple in structure and easy to operate.It can be effectively used to remove icing from high voltage transmission lines.
