Haixi news from our newspaper (reporter Zhang Hongxu, correspondent Wang Zhenpeng) “in the past, special personnel were assigned to squat at the external breaking points, which took time and effort, and achieved little results. Now with the electronic Qianli eye, we can access the information of line operation conditions at any time, and check the icing of the line.” Recently, Haixi power supply company of State Grid Qinghai electric power company found an abnormality on a 110 kV line conductor through the panoramic monitoring platform of the transmission line, and immediately informed the transmission operation inspection personnel to rush to the scene with special instruments to eliminate the potential safety hazards in time.

As most power supply lines are located in remote places and exposed to the wild all year round, the probability of line failure caused by natural disasters such as wind and sand, human factors and external force damage shows an upward trend. In view of this situation, Haixi power supply company promotes the safe operation of power grid with the integration of digitization and computerization, establishes and improves the account files of hidden danger points damaged by external forces, divides the nature and degree of hidden danger, and accurately implements special line patrol.

In addition, the company also installed 360 degree video surveillance cameras in special areas such as three cross lines and external damage. Through the transmission line panoramic monitoring platform, the company carried out all-round and non dead angle real-time monitoring of the line, so as to realize the security control of “cloud, number and intelligence”.

According to reports, the monitoring platform will conduct frequency recording and screenshot processing on its own after discovering hidden dangers, with a visual distance of 1000 meters. At present, the company has installed 23 video surveillance cameras in Golmud City, Dachaidan and other areas, flexibly connected to the panoramic monitoring platform, so that there is no hiding place for external damage, enhanced the “observable, measurable and controllable” ability of the power grid system, and ensured the safety, controllability, on-site control and controllability of the power grid.
