From 8:30 in the morning, the crisp "click" sound filled the relay working area of the signal maintenance workshop of the China Railway Qinghai-Tibet Group Co., Ltd. Golmud Electric Dept. The "women's army" were busy with the maintenance with their heads down.
"A palm-sized relay needs more than 60 processes from maintenance to delivery. We dare not be a little sloppy. The work area is very quiet during work." He Zengmei, the foreman of the work area, told reporters.
He Zengmei introduced that the relay is the "heart" of the railway electrical system. It is installed in the machinery room of the station and serves the railway operation together with other equipment.
"The characteristics and mechanical characteristics of the relay will change to a certain extent during long-term use. If the maintenance is not timely, the damage will affect the normal operation of the train."

The relay work area where He Zengmei is located has a total of 9 people, all of whom are female workers, so the team is called "the Women's Army".
Mainly responsible for the overhaul and maintenance of more than 30,000 relays on the Xige Line, the Gela Line and the Geku Line, the quality inspection of the new relays and the acceptance work of the testing laboratory, and guarding the stability and smoothness of the Qinghai-Tibet Railway.
The Qinghai-Tibet Railway is one of the four major projects in the new century in China. It is the first railway to the hinterland of Tibet. It is also the plateau permafrost railway with the highest altitude, the longest plateau line mileage and the worst operating environment in the world. sky Road".
He Zengmei is holding the pressure gauge in one hand and the relay armature in the other, carefully testing the contact reeds of the relay, and scanning the indicator light of the test bench with his peripheral vision.
"The uniformity is not good enough." After that, she picked up the rubber to wipe off the stubborn oxides on the surface of the contacts, skillfully dipped a cotton cloth with alcohol, and carefully wiped the parts of the relay.

"Her eyes are 'eyes of fire'. As long as she picks up the relay, she can see the slight difference between the contacts and gaps in millimeters." Colleague Cheng Ziyi admires He Zengmei from the bottom of his heart.
"After a relay is disassembled, there are as many as 24 kinds of parts, the smallest of which is only a few millimeters. To ensure the reliability of each relay, it is necessary not only to be able to do 'technical work', but also to be able to do 'fine work'." Deputy engineer Chang Li Zengying said that the maintenance of a seemingly small relay requires multiple procedures. There are 35 maintenance tools, and each maintenance process requires fine maintenance and adjustment as "embroidery".
The relay contact pressure, which is counted by horns, is equivalent to the force of lightly touching a feather, but Yang Xiaoyan, an old employee, "handles it" very accurately.
"With the tip of your index finger, you can sense the qualified pressure. When the qualified relay is driven in by the positioner and the reverser, there will be a crisp sound between the armature and the pole shoe." Yang Xiaoyan picked up a relay, Talk while presenting.
By seeing, hearing, and touching, you can judge whether a relay is "sick". In this team, everyone has their own tricks.
"We are both artisans and doctors of traditional Chinese medicine." He Zengmei explained their work.

It takes more than an hour for a relay to be repaired at a time. If it encounters a "problem", it is common to be busy for seven or eight hours.
In 2021, in this "contest" with a slight difference, the "Deputies Army" completed the maintenance and test tasks of more than 3,000 signal relays, and the pass rate reached 100%.
The thin shoulders of the "Department of Women" can withstand the "wind and rain", and can also bear the "big beam".
In July 2020, the construction of the Goku Railway entered a critical period, and in the event of epidemic prevention and control, they worked overtime for more than 20 consecutive days to complete the inspection of 7,879 equipment at 18 stations on the Goku Line, ensuring the progress of the Goku Railway project.
In 2021, the original equipment of the signal maintenance workshop of Golmud Electricity Dept. will be relocated as a whole. .
During the Spring Festival in 2022, the number of trains will increase, which will be a big test for electrical equipment. The "Department of Women" are more serious than ever, playing the "Waltz" with their fingertips for the safe operation of "Sky Road" equipment.
"Sitting for a long time during maintenance often leads to backache and backache. Even if I stare intently during maintenance, my eyes can't control the tears." Worker Ma Haihua joked: "We all burst into tears when we work." (Finish)
