Method and system for laser deicing for power transmission and transformation equipment

The invention discloses a method and a system for laser deicing for power transmission and transformation equipment. The method comprises the steps of: adopting laser frequency conversion technology and a galvanometer scanning focusing principle; adopting a continuous or long-pulse solid laser as core deicing equipment; outputting infrared laser, partially converting the infrared laser into visible laser; coaxially outputting the infrared laser and the visible laser; focusing and irradiating on an ice-covering area of the power transmission and transformation equipment to deice through a collimating mirror, two scanning galvanometers and a focusing mirror; adopting control equipment to control the opportunity and the time of laser output of the laser and the vibration of the scanning galvanometers to ensure that the laser irradiated on the ice-covering area of the power transmission and transformation equipment performs two-dimensional mobile scanning; and observing the irradiation position of the visible laser through a tracking and aiming device to prevent the laser from damaging the power transmission and transformation equipment. The system has small volume and light weight, realizes the long-distance focusing of the laser, is favorable for removing large-area ice coating, realizes the tracking and observation of the laser deicing, prevents the laser from damaging the power transmission and transformation equipment, and can remove ice layers under the condition of no poweroff for a conducting wire iron tower; and the system can also be used for the deicing of the power transmission and transformation equipment such as insulators, overhead transmission lines, iron towers and the like.
