On August 16, State Grid Bortala Power Supply Company organized personnel to carry out independent inspection of drones on the 10-kilovolt line. Distribution line inspection is the focus of power supply guarantee work. Drones have become an important tool for distribution network line inspection. 

Compared with the previous manual operation of drone inspection methods, drones equipped with adaptive inspection technology do not require staff to remotely command. With one-click operation, a series of tasks such as identifying poles and towers, infrared temperature measurement, and taking pictures can be completed independently.

In order to effectively improve the application effect of independent drone inspection and effectively support the construction and application of a new power system and the construction of core business teams, the company planned in advance and established a joint research special group for adaptive inspection of distribution network drones with Information Industry Group Co., Ltd. and Zhongke Fangcun Zhiwei (Nanjing) Technology Co., Ltd. 

Through top-down linkage, main production coordination, "training + practical operation," and "outsourcing + independence" methods comprehensively promote full coverage of independent inspection of distribution network drones.

"After adopting adaptive technology, a drone with a team of two people can complete a 10-kilometer inspection task in one day, which is equivalent to the workload of our previous week of walking inspection. This greatly improves the work efficiency at the grassroots level," said Li Jingtao, an employee of the company.

As of now, State Grid Bortala Power Supply Company has used drones for independent inspection of 110 10-kilovolt lines, 36,700 poles and towers, a total of 1,815.93 kilometers, and discovered and dealt with 10,300 various defects. 

In the next step, the company will explore and deepen the application of drone adaptive technology, strengthen cooperation and exchanges in related fields, draw on advanced experience, better achieve lean operation and maintenance of the distribution network, serve and ensure that the operation safety of grassroots personnel is controllable,work is cost-reduced and efficiency-increased, and fully guarantee the safe and stable operation of the power grid.
