On May 21st, a mysterious instrument was unveiled at the site of the 110-volt Volt I, II 36-37 iron tower of the State-owned Xining Power Supply Company. The company’s transmission and inspection personnel used the mysterious instrument to complete the line foreign object removal operation in just two minutes.
It is reported that the mysterious instrument used by the State-owned Xining Power Supply Company in the line foreign object removal operation is a portable power grid laser system for removing foreign matter. The instrument ensures safety by irradiating the green laser pointer beam of appropriate energy onto the foreign material of the long-distance transmission line. Under the premise, the part wound on the wire is burnt, so that the foreign matter is dropped, and the rapid and effective removal of the foreign matter under the condition of the line being electrified is realized.
Overhead line foreign matter hanging line is one of the main reasons leading to unplanned outage of the line, especially in spring and summer, accompanied by windy weather, plastic sheds, agricultural mulch, kites, metal streamers and other foreign objects hanging frequently. State Grid Xining Power Supply Co., Ltd. actively introduces advanced instruments to help improve production efficiency in light of the current situation of the season and the combination of traditional safety measures such as high safety risk, long time-consuming operation and high labor intensity. On the same day, the company’s transmission and maintenance personnel accurately selected the placement position of the green laser pointer instrument, reasonably arranged the clearance angle, and successfully completed the foreign matter removal operation between the 110 kV spring sinking I and II back 36-37.
In the next step, the company will continue to carry out the application research of advanced methods such as laser removal of foreign materials on the transmission line in combination with the actual needs of the transmission line operation, and make the foreign matter cleaning work fine and solid, and lay a solid foundation for the safe and reliable operation of the transmission line.
