At midnight on February 1, among the 100,000 mountains along the Guinan high-speed railway, the Ruyi substation was brightly lit, and the post-95 master Jing Yanting took the post-00 apprentice Wei Hanshu to start the first Spring Festival "climbing" skylight operation of the master and apprentice.
Between the reckless mountains, a silver bridge flies across, and there are moving cars whistling past. Ruyi substation is located in Mashan County, Nanning City, Guangxi Zhuang Autonomous Region, and undertakes 91 between Du'an Station and Nanning North Station of Guinan High-speed Railway92 km of railway power supply mission, through the combination of electrical equipment to convert 220 kV high voltage to 27The 5,000-volt railway special power supply is delivered to the railway catenary to provide continuous kinetic energy for the bullet train, and is the power supply "heart" for the continuous "pumping" of the main artery of railway transportation.
Fasten your seat belt tightly, move quickly and lightly, and do as you normally would. Jing Yanting told Wei Hanshu. The master and apprentice climbed onto the outdoor platform to clean the insulator stains. That night, they had to overhaul, test and maintain all the system equipment inside and outside the substation pavilion.
This is Wei Hanshu's "first climb" in the Spring Festival, more than 2 meters above the ground, not tall, but to stand on a prism about 10 centimeters wide to maintain the equipment, while maintaining balance and work speed, the girls are calm and well-trained.
In the team, there are 25 young female employees like Wei Hanshu. The average age of the women's maintenance team in the Nanning South Maintenance Workshop of Nanning Power Supply Section is 28 years old, and they run all year round between the mountains and mountains of 11 Gaopu railway lines such as Nankun, Nanguang and Guinan, and operate and maintain substation and distribution equipment. This year, the Guinan high-speed railway ushered in the first Spring Festival, and the number of substation kiosks they were responsible for inspection and commissioning increased to 99.
At the end of the insulator "pass", the master and apprentice came to the transformer "checkpoint". After Yan Ting took the lead, she quickly climbed to the top of the transformer with her hands and feet and carefully investigated. She expertly inserted the wrench into the nut and tightened a loose screw. "A missing screw may cause a large-scale sudden power outage, and it is necessary to work hard in the early morning to ensure the safety of power supply. In her opinion, the maintenance work seems to be easy, but it is not sloppy at all.
After Yanting talked about the business, she was meticulous in implementing the operation standards, and she taught the apprentice a serious face, in fact, she was also a 26-year-old girl. This year is the 5th Spring Festival of her work in the railway post, and it is also the first Spring Festival of taking her apprentices into battle. "The Spring Festival transportation is busy, and we have a sense of awe for safety, and we must tighten every screw and open every skylight to ensure the safety of passenger trains and the smooth flow of railway transportation. In her eyes, the science of power supply is complex, as a substation maintenance worker, we must understand and master more professional knowledge, accumulate more on-site experience, and maintain learning and progress in order to go further.
In the mountains in the early hours of the morning, the exhalation turns into fog. After 6 hours of hard work, Yan Ting, Wei Hanshu and a group of 5 people assembled into a team to complete the skylight operation.
