Red Network Moment News, February 26 (Correspondent Cao Daozhi) Affected by the fourth round of low temperature rain, snow and freezing weather, some transmission and distribution lines in the alpine mountains of Linwu County began to be covered with ice on February 22. In this regard, Chendian International Linwu Branch rose to the "cold", organized personnel to carry out line inspections and ice monitoring, and started anti-freezing and thawing according to the critical value of line icing, so as to ensure the safe and stable operation of the power grid.
On February 24, the day of the festival, the temperature was minus 1 degree Celsius. Early in the morning, Tang Aijun, an employee of the Line Management Office of Chendian International Linwu Branch, set off again with two colleagues to patrol the ice road.
Our main task today is to continue to inspect the 35kV water wiring and 110kV water line to observe the ice changes of the line. "This time, it was Tang Aijun and his colleagues who inspected the two transmission lines for three consecutive days.
Since the third round of low temperature, rain, snow and freezing weather in early February, Tang Aijun and his colleagues have been fighting on the front line of ice inspection, line de-icing, fault repair and anti-ice power protection for nearly one month, and even on Chinese New Year's Eve and Spring Festival, they have not been able to reunite with their families.
The 35kV water connection is the main transmission line of the Solitaire substation, with a total length of 88 kilometers, there are 32 power towers, more than half of the towers are in high-altitude mountainous areas, in the event of freezing weather, the line is one of the first lines of Linwu power grid to cover ice.
During the low temperature, rain, snow and freezing weather, the mountain is high and the road is slippery, the mountain is foggy, the visibility is low, and the bamboo and trees that are overwhelmed by the ice and snow are all over the place, which brings great obstacles to the work of walking on the snow and patrolling the line to watch the ice. ”
Shouldering the mission of power protection, we are not afraid of the cold to move forward. The group cleared the obstacle all the way, measured each base tower with footsteps, observed and recorded the icing situation of the line at close range, and sent the icing information and information to the emergency power protection commander at the first time.
At 2 o'clock in the afternoon, after inspecting the last base tower of the water connection, Tang Aijun and his colleagues "sat on the ground", hurriedly ate some dry food brought by themselves, and rushed to the Furong substation in Beihu District to start another round of ice monitoring at the ice viewing point of the next 110kV Shuifu line.
In order to accurately grasp the icing thickness of the line, so that the emergency headquarters of the branch can analyze and judge and start the anti-freezing and ice-thawing plan, Tang Aijun and his colleagues braved the severe cold of minus 3 degrees Celsius in the mountains, and had to climb the 43 and 56 towers, the highest altitude, every 2 hours to conduct an ice observation inspection, run back and forth between the two towers, record the icing situation of the line in detail, and accurately grasp the icing status of the line.
Because the error will occur inverted rod broken line, so the icing situation should be repeatedly observed and confirmed, can not be taken lightly, every day with dry food rolling on the mountain, if the road is frozen and restricted, with the help of nearby villagers, until the temperature rises after the line thaws ice before going down the mountain ......Big data is normal, the power grid is safe, and the hard work is worth it. Talking about the original intention of the power people, Tang Aijun was moved.
Up to now, in the process of the fourth round of low temperature snow and freezing weather, Chendian International Linwu Branch has organized 175 people to carry out inspections, ice observation and artificial de-icing of transmission and distribution lines, and started anti-freezing and de-freezing of 5 lines of 35 thousand volts and above in high-altitude mountainous areas such as Wanxiang and East Railway.
