Ice melt on the main line.
Ensure the stable power supply of high-speed rail traction lines.
The icing of the 110 thousand volt calamus line has reached 7 mm, which seriously threatens the safe operation of the transmission line! "The cold wave continued to blow, the minimum temperature continued to fall below freezing, and the white line was covered with a layer of silver armor.
The Jiabai line mainly supplies power to many important users such as high-speed rail traction transformers, and the icing of the line has brought serious safety hazards to the power supply of high-speed railways during the Spring Festival. The substation maintenance company heard the order and immediately rushed to the scene.
Received, let's do it right away! After receiving the ice melting notice, the company immediately organized the operation and maintenance team to re-examine and re-inspect the ice melting plan, operation ticket and scheduling order of the line, reconfirm and re-verify the ice melting equipment and materials, and cooperate with multi-professional maintenance personnel for the first, second and test tests to ensure the smooth progress of the entire ice melting process.
At about 14 o'clock on February 5, after the dispatch issued the instruction, the operation and maintenance personnel immediately began the operation of reversing the gate. Sub-zero temperatures, foggy skies, and cold rain mixed with snow particles hit the faces of the operators, but everyone kept an eye on the work at hand, and carried out each instruction in an orderly manner according to the operation ticket, so as to build a reliable electric flow path for the ice melting of the line.
At 6:50, pull open the 332 circuit breaker and cut off the ice melting current! "At 7 o'clock in the morning of February 6, with the thick ice on the line falling off, the ice melting work that lasted for nearly 19 hours in the freezing rain was completed, and the hidden danger of icing on the line was eliminated, ensuring the continuous and stable power supply of the high-speed rail traction transformer.
"Light up" on a cold night and go up the mountain to remove the ice.
Guanghan Village in Guanghe Village, Huangfengqiao Town, Youxian County, is located in the alpine mountains at an altitude of more than 1,000 meters, and the icing situation on the lines passing there is more serious than in other places, and some residents' homes are without electricity.
All of them are in battle tonight! Be sure to fight the 'Battle of Guanghan Village' to ensure that the people have electricity for the New Year! ”
On the evening of February 5, Zhu Huijiang, deputy director of the Huangfengqiao Power Supply Station of the State Grid Youxian Power Supply Company, received a **, located in Guanghan Village, the 10kV Yueguang line was seriously covered with ice, and the situation was very urgent, in order to ensure the electricity consumption of more than 100 residents in the Taiwan District, Zhu Huijiang quickly "put on armor and went into battle", gathered and led a group of party members and "soldiers" of the Huangfengqiao Power Supply Station to set off immediately and quickly investigate the scene.
The road is not easy to walk, I will open the way, and you will all follow me! Be safe! Zhu Huijiang said.
The soldiers "arrived in the mountains, the slippery road vehicles could not walk, everyone could only get off the car and walk up the mountain in the rain, the trees and bamboos on both sides of the mountain road were bent by the ice, blocking the way of the team members, the mountain road after the ice was more difficult to discern the direction than before, the experienced Zhu Huijiang had already been familiar with these lines, in order to reach the destination as soon as possible, he charged ahead, picked up a wooden stick to beat the ice, and opened up a path with tools, the wind carried the freezing rain, like a knife cutting his cheeks, and the low temperature had already frozen his face and hands red, the overalls hat is already full of ice cubes that can fall at any time.
Zhu, there are a total of 26 poles that are seriously iced, and the task is heavy, so we don't have enough manpower. ”
Don't worry, I have already contacted the secretary of the Guanghe Village Party Committee in advance, and their people are also on their way. ”
As early as the early warning period of freezing rain and snow weather, Zhu Huijiang communicated with the main persons in charge at the village level in advance and actively sought the support of local departments. After receiving the emergency repair, Zhu Huijiang immediately contacted the secretary of the Guanghe Village branch. At 12 o'clock in the evening of February 5th, the government and enterprises successfully "met". After Zhu Huijiang briefly explained the work tasks and risk reminders, several people performed their duties and quickly entered the "combat" state, reported and dispatched on the spot, and carried out emergency repairs as soon as possible after doing a good job of safety measures. The mountainous environment is complex, and the light is dim at night, Zhu Huijiang has always insisted on staying at the scene to command the emergency repair work, personally checking every risk point without leaving hidden dangers, and synchronously directing the restoration work of other fault points. After four hours of fierce fighting, the icing of the lines of the 26 base poles was completely cleared, and the power supply was restored in the jurisdiction.
Since the rain and snow, the State Grid Zhuzhou Power Supply Company has launched an emergency response to low-temperature rain, snow and freezing disasters, inspected the whole network, concentrated on eliminating shortages, and made every effort to ensure the safe, efficient and stable operation of the power grid and ensure that the masses are warm for the holidays.
