China's well-off network, February 8 "At present, the wind speed is up to about 5 meters per second, and the temperature is minus 3At 5 degrees, there is icing on the tower and overhead lines. On February 7, Cai Jianli, director of the engineering department of Zhejiang Jinhua Power Transmission and Transformation Project, was monitoring the on-site icing of the 500 thousand volt line located in the northwest mountain of Pearl Slope in Pingjiang County, Yueyang City, Hunan Province.
It is understood that in the past few days, Hunan Province has ushered in a new round of rain, snow and freezing weather, and this round of freezing weather lasted until the 8th, and the rain, snow and freezing disasters have brought severe challenges to the safe operation of power grid equipment in various places. In accordance with the unified deployment of the higher-level departments, Jinhua Power Transmission and Substation Company successively sent 13 professional backbones, 28 construction personnel, and 11 anti-ice rescue vehicles to Yueyang, Hunan Province to carry out anti-ice rescue work. After a short rest, the temporary command decided to put into work immediately, and decided to divide into three groups to conduct a special patrol and detailed survey of the emergency repair task, further grasp the on-site road, climate and other information, speed up the repair efficiency, and complete the work task as soon as possible.
Due to the heavy snowfall, the road up the mountain has become a little difficult to identify. Time was pressing, in order to grasp the details as soon as possible, the rescue team found a tower relatively close to the hometown road, climbed over the mountains and mountains along the direction of the line, and opened up a simple passage between the mountains and forests that only allowed one person to pass through most of the sections. This simple walkway, which can only be walked, is the only way for people to pass and transport equipment, and it takes about 6 hours to make a round trip.
The end of this route is ahead, be careful of the slippery road, everyone pay attention to safety and hurry up to keep up. Xu Zhiyong, the leader of the support mission of Jinhua Power Transmission and Substation Company, shouted loudly to the rear. The snow blocked the road and vehicles could not pass, so the team members of the on-site investigation walked over with tools; Walk on the ice and pour the bamboo line, wave the firewood knife and cut it one by one before moving forward; During the climbing, I fell and got up again and again, just to complete this on-site exploration in the shortest possible time.
The snow is at least over 5 centimeters! The fog is too big to be seen by the naked eye. Inspector Liu Jianchao said. In the No. 76 Tower, which is the most difficult to walk on the road, the white fog is full and the visibility is low, and the overall condition of the tower cannot be reliably analyzed by the naked eye alone, so the team members can only take out drones to assist in the survey. "The special inspection helps us to quickly and comprehensively grasp the defect situation, which is convenient for the deployment of follow-up repair work forces and the arrangement of construction personnel. Lv Zhaohui, commander of State Grid Jinhua Power Supply Company, explained.
The relevant person in charge of Jinhua power transmission and transformation project said that the next step will be to actively support the State Grid Jinhua Power Supply Company to carry out anti-ice rescue work, overcome all difficulties and obstacles, go all out to win the battle of stable power supply and supply, and continuously improve the quality of power supply services in northern Hunan to ensure that the people can rest assured that they can use electricity and stay warm in winter.
