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.
