State Grid Yongjia County Power Supply Company precisely carried out the "aorta"

"The installation of the minefarers of the 35 kV Rock Sali 3651 has ended, the ground work ground line has been demolished, the membership class has been evacuated, and the line has the conditions for power delivery." On June 28th, as the transmission and transportation inspection class work was responsible for responsibility The end of the personnel to the scheduling report line marks that all the 35 kV lines in the northern mountainous area of ​​the State Grid Yongjia County Power Supply Company have completed the installation of the lightning absorber. During the peak summer, in order to ensure the safe and reliable operation of the line, the State Grid Yongjia County Power Supply Company was installed to further improve the lightning protection ability of the main network line by installing a lightning molar.

It is understood that the summer lightning and electricity activities in the Yongjia area are frequent. Due to the high terrain in the mountains, the number of lightning strikes in the northern mountain area in 2021 is as high as 14489 times. Work, organize relevant professional staff to inspect and inspect the power grid prevention and lightning protection facilities. At the same time, through drone special patrols and infrared temperature inspection, carefully check the hidden dangers of the line after lightning, and successfully complete 9 5 kV lines in the mountainous area of ​​the northern Yongjia. 462 Trunctiva. For rod towers with high ground resistance, in addition to traditional means such as increasing burial depth and grounding body, for severe grounding lines, the State Grid Yongjia County Power Supply Company uses flexible graphene grounding for the first time. This material has better conductivity. , Corrosion resistance, effectively reduce ground resistance, and have better resistance to direct strikes.

State Grid Yongjia County Power Supply Company comprehensively considers the characteristics of lighting line corridors, line structures and other characteristics, refine the dangerous lightning distribution area that threatens the line operation, marked the rampant area, easy to hit the tower, and clarify the key lightning protection area and prevention of the transmission line. Thunder measures. Strengthen the communication with the meteorological department, closely grasp the weather changes, issue early warning signals, start the thunderstorm emergency response plan, and make early preparation and early prevention.

In the next step, the State Grid Yongjia County Power Supply Company will combine the weather and lines in previous years to further improve the emergency treatment plan such as lightning protection and flood prevention, rehearsing the lines of the far mountains, and a good reserves of repairs to ensure the reliability of grids in the thunderstorm season.
