The Spring Festival is approaching, when you decorate your small home, a transmission and distribution "vein" extending in all directions is providing energy security for thousands of households.
On February 2, the twenty-third day of the new year, the staff of the State Grid Qinhuangdao Power Supply Company incarnated as the "pulse keeper" of the underground cable and carried out an "underground touch" on 1,314 high-voltage transmission and transformation cables of 220 thousand volts and below in the underground cable channel.
The pitch-black cable trench is the only tool of illumination, and the members of the cable remediation team need to find the problem in the hundreds of kilometers of cable trenches that crisscross it.
They are in groups of 2 to 3 people, wearing respiratory protection equipment, portable gas detection alarms, lights and walkie-talkies and other professional equipment, and cooperate with various test instruments to carefully check whether the main structure of the channel is damaged, whether there is water seepage and water accumulation, whether the toxic and harmful gases exceed the standard, and the cable joints and outer sheath in the channel and the transportation conditions.
The cable trench belongs to the limited space operation, before entering the underground to confirm the oxygen content and toxic gas in the cable trench is the first process, the national May Day Labor Medal winner, the cable inspection center of the second class of technician Zhang Gengxi has a wealth of experience in testing and testing, he led the team members to use the gas detector every step forward to "explore".
The inspection of underground cables is difficult, and the humidity and temperature may affect the technical parameters, and there is no room for the slightest omission.
It's freezing cold, and they have to be quick with their hands and feet to meet their deadlines, moving quickly under their feet, their brains racing at high speeds, and only slowing down when they find "suspicious" parts.
The team members said that sometimes working in the dark cable trench made it difficult for them to distinguish between day and night, and the only opportunity they had to "rest" was the open exit or ventilation area.
In order to ensure reliable power supply during the Spring Festival, Zhang Gengxi and his "underground alliance" will complete 73 main grid substations in six districts and three counties of Qinhuangdao City, with a length of more than 310 kilometers and 1,314 transmission and transformation cables"Great arteries"This is not only a skill verification, but also a "big test" of endurance.
The end of this "underground touching" has effectively improved the stability coefficient of cable equipment operation, better guaranteed the safety of power supply, and ensured that the people have a bright and bright year. (Li Rongrong, Xu Mingsi).
