It is understood that the sudden rainstorm in the early morning of 24th caused the river to flood the county town and most towns, resulting in the voltage loss of five substations, such as 1 10KV external transformer, 35KV ballast transformer and 35KV ballast transformer, and the 18 10KV line was forced to be cut off. Among them, the two sides of the 35 kV Zhenba substation were hit by mudslides, the walls collapsed, and the equipment of the substation accumulated water up to 32 cm. After the disaster, Shaanxi local electric power Hanzhong branch immediately sent people to Zhenba. At 3: 40 in the morning, the repair personnel arrived, but they could not enter because of the road interruption.
Zhenba county Power Supply Branch organized emergency teams and emergency materials to rush to the site, and comprehensively carried out emergency repair work according to the principle of "high before low, trunk line before branch line, power supply before perfection, town before township, simplicity before complexity".
Zhenba county is the county most affected by this flood. The road was interrupted and the bridge was damaged, so the power supply maintenance equipment could not reach the emergency repair site by vehicle transportation. The emergency repair team members of electric power transport the urgently needed emergency materials to the construction site by breaking down the wires into small bundles and carrying them on their shoulders, and carrying small materials such as fittings, porcelain bottles and tools on their backs. The longest walking distance exceeds15km. In order to solve the problem that the poles can't be transported in time, the emergency repair team members bought more than 8 meters of wooden poles instead of cement poles to support the wires. At the same time, in view of the current situation of tight time, heavy tasks, inconvenient transportation and scattered and far-reaching emergency repair points, zhenba county Power Supply Branch reasonably arranged technicians and site operation supervisors of each emergency repair team, and coordinated the township (town) government to mobilize villagers to dig pits, carry materials and erect poles, which effectively improved the construction efficiency.
In order to restore power supply as soon as possible, zhenba county Power Supply Branch made every effort to carry out emergency repair, and at the same time adjusted the power supply scheme in time and reported it to the superior for approval, and temporarily changed the power supply operation mode for some towns such as Bashan, which were particularly damaged and difficult to restore in a short time, so that the damaged lines could restore power supply in time.
On July 23rd, Hanzhong Power Supply Branch dispatched 80 elite soldiers from Chenggu, Yangxian and Xixiang Power Supply Branches to form a commando team to support Zhenba disaster area. Relevant leaders of Shaanxi local electric power company recently went to Hanzhong Zhenba, Xixiang and other disaster areas to check the disaster situation, and asked all employees to carry forward the team spirit and the spirit of being particularly hard-working, and to make all-out efforts to ensure power supply as the primary task at present.
