Instructions for use of laser cleaning device for foreign matters in power grid

At present, the removal of foreign matters on transmission lines in China often depends on manual methods. However, with the increasing application breadth and depth of foreign matter removal lasers and the increasing scale of unmanned operation, foreign matter removal lasers have been used to assist in transmission line inspection in the power industry and achieved many results. Through the research and comparison of several foreign matter removal devices for transmission line, and combined with the application of rotor foreign matter removal laser, this paper studies a line foreign matter removal device suitable for the current application of transmission line foreign matter removal laser team, and analyzes the technical means of professional foreign matter removal laser.

At present, when there are foreign matters such as plastic film, kite and fishing line on the conductor and ground wire of transmission line, it mainly depends on live working or power failure maintenance. The live line operation consumes a lot of manpower and material resources, and the safety risk is also large. The power failure operation needs to wait for a long time, and the foreign matters will affect the operation safety of the line for a long time. It is urgent to study a device and method that can not only deal with it in time, but also reduce personal safety risk to remove foreign matters from the line.

In addition to foreign matters, at present, domestic and foreign transmission lines are mainly cleaned manually with electricity, or metal tools are used in case of power failure and electrification. Foreign matter removal robots are also used in tests, but personnel are required to participate in a high degree to send tools and instruments to the conductor, which has high labor intensity and safety risk, However, there is no application of foreign matter removal by using foreign matter removal laser to mount foreign matter removal device

Therefore, the emergence and application of foreign matter removal laser is the inevitable trend of safe operation of the line and solving the personal safety of operators. Therefore, it is necessary to borrow the foreign matter removal laser platform to develop a lightweight, convenient and safe cleaning tool that can quickly deal with foreign matters in the line without entering the high-voltage and strong electric field.

Working instructions of laser clearing device for foreign matters in power grid

The continuous laser is used as energy to irradiate the foreign matter with the laser beam emitted by the laser foreign matter removal device of the transmission line, form a laser ablation area on the foreign matter, and ablate or divide the foreign matter as a whole, so as to realize the non-contact live removal of non-metallic foreign matters such as kite line, plastic film, canvas and advertising banner hung on the high-voltage power transmission and transformation equipment.

Safety of laser clearing device for foreign matters in power grid

After the laser beam shaping treatment, the laser beam directly irradiates the foreign matter and wire. The treated laser beam will not damage the metal wire, but can only gasify and melt the non-metallic material.

The surface of the metal wire has a strong reflection effect on the laser. Under the same conditions, the energy absorbed by the metal wire is much less than that of the general metal wire, and the thermal conductivity is much higher than that of the non-metallic foreign matter. Therefore, when absorbing the same energy, the wire quickly releases heat through heat conduction, surface heat radiation, convection and other ways. The conductor is generally composed of steel, aluminum, zinc and other alloys, and the melting point is much higher than that of conventional non-metallic materials. Therefore, controlling the temperature within a reasonable range can fuse the foreign matter without damaging the conductor. If the device directly irradiates human eyes or skin, it will cause damage. Therefore, our products are equipped with many measures to ensure safety, prevent misoperation and protect the safety of operators.
