Operations and maintenance staff carry out a special inspection and temperature check at the 110 kV railway station substation

To ensure reliable power supply during the May Day holiday, State Grid Zhangye Power Supply Company adopted a three-pronged approach combining manual inspections, video monitoring, and intelligent robots to conduct comprehensive checks of 330 kV and 110 kV substations within its jurisdiction. The Company completed inspections of multiple sets of equipment, rectified identified hazards through closed-loop management, closely monitored key risk points, and increased inspection frequency to strengthen equipment condition monitoring. The substation monitoring team implemented a 24-hour, dual-person, dual-post duty system, closely tracking grid operating data to achieve a response to abnormal signals within seconds and accurate assessment, while leveraging intelligent systems to improve emergency response efficiency. The Company also organized multiple emergency repair teams and ensured that personnel, vehicles, and supplies were all in place. The teams remain on round-the-clock standby and carry out drills to ensure rapid fault response and efficient handling. (Text/Photo by Wang Xiaoya and Cheng Gang)
