On Aug 12, State Grid Shizuishan Power Supply Company comprehensively launched the special troubleshooting of substation leads and insulators, innovatively adopted the dual troubleshooting mechanism of "manual+intelligent patrol", aiming to make full use of the meticulous manual patrol and the accuracy and efficiency of the intelligent patrol system, form complementary advantages, ensure the comprehensiveness and accuracy of the troubleshooting, and ensure the safe and stable operation of power grid facilities.

In the process of inspection, the operation and maintenance personnel of Shizuishan Power Supply Company of the State Grid wore work clothes and braved the scorching sun to conduct meticulous inspection of every lead and insulator in the substation. Key problems such as whether key hardware such as lead cotter pins and nuts are missing, whether the cotter pins are opened correctly, and whether the bolts are fastened in place are checked. As hardware, cotter pins and other components are mostly suspended from height, operation and maintenance personnel have to raise their heads for a long time in high temperature, which not only tests their physical strength and endurance, but also puts forward extremely high requirements for vision. As time goes by, sweat inevitably flows into the eyes, adding more challenges to the already arduous troubleshooting work. But even so, the operation and maintenance personnel still stuck to their posts and ensured the smooth progress of the troubleshooting work with a high sense of responsibility and professionalism.

In order to relieve the pressure of manual inspection and improve the inspection efficiency, State Grid Shizuishan Power Supply Company also makes full use of the intelligent inspection system to realize remote monitoring and intelligent analysis of the substation through advanced equipment such as high-definition camera and infrared thermal imaging. Just sitting in the monitoring room, the operation and maintenance personnel can view the situation in every corner of the substation in real time through the large screen, and timely discover and locate potential safety hazards. The intelligent patrol system plays an irreplaceable role in the high places and hidden areas that are difficult to reach by manual patrol inspection. In the next step, the company will continue to deepen technological innovation and management innovation, continuously improve the power grid security management level, and make every effort to ensure the safe and stable operation of the power grid.
