Chapter 207 Ensuring Electricity Delivery
After half a month of hard work day and night by the electrification engineering staff, the final construction tasks of each major were pushed forward bit by bit, and the internal professional processes were indeed much smoother due to the high-pressure management of the headquarters, and the communication with external units The inter-professional coordination work is also very smooth. Two days before the catenary power transmission on September 9th, after the full cooperation of the construction unit and the supervisory unit, the cold sliding test of the entire line catenary was successfully completed, which paved the way for the next stage. Electricity lays a solid foundation.

It wasn't until this time that the staff of the command headquarters saw the rare smile of their commander Mao Shaohua again.

Ren Shuxia has not been idle these days. She has organized and held on-site work coordination meetings many times, compiled a detailed "Implementation Plan for Catenary Power Transmission", established a leading group for power transmission, and strictly followed the plan to standardize the procedures for the entire line of catenary before power transmission. Conducting cold sliding tests, issuing power transmission notices to towns and villages along the road, and inspecting the line in a timely manner after power transmission, strictly controlling safety and quality, and fulfilling the main responsibility, laid the foundation for the Beijing-Zhangjiakou high-speed railway to smoothly enter the joint commissioning and testing.

On the day of September 2019, 9, it is a memorable day for all the electrification engineers who participated in the construction of the Beijing-Zhangjiakou high-speed railway.

At 9:4 on September 21th, with the dispatch order of railway power supply dispatched, the traction substations of the Beijing-Zhangjiakou High-speed Railway constructed by the Central Plains Electrification Bureau were closed and sent power one after another. The realization of "electric communication" on the entire line of the Beijing-Zhangjiakou high-speed railway has created a prerequisite for the next step to carry out the live-line hot sliding test of the catenary.

Later, in front of many media reporters, the commander Mao Shaohua said with emotion:

"The transmission of electricity from the railway traction substation to the catenary is an important node in the process of building a new high-speed railway. As the "last stick" in the construction relay race of the Beijing-Zhangjiakou high-speed railway, the catenary It directly undertakes the important task of providing a strong source of power for high-speed trains, and it is also the most critical control project for the smooth realization of "Diantong" to ensure the power consumption of all stations and train equipment and to realize the joint commissioning and testing of all equipment on schedule."

Finally, Mr. Mao also specially popularized the professional interpretation of catenary power transmission to media reporters:
"The catenary power transmission process refers to the transformation of the 220 kV high voltage of the national and local power grids into 27.5 kV single-phase power-frequency AC power through the railway traction substation and then transported to the catenary above the high-speed rail line to provide train operation. Kinetic energy. After power transmission, the catenary conductors of the entire line of the Beijing-Zhangjiakou high-speed railway can be directly charged up to 27.5 kV.”

Ren Shuxia's mood was quite complicated at this time, and she was extremely excited. She couldn't help calling Yu Baoqing, the former chief engineer of the Beijing Zhangsi Electric Headquarters of the group company who was still on sick leave at home;
"Mr. Yu, our Beijing-Zhangjiakou high-speed railway catenary professional has successfully delivered power today!"

In the dark night, Mr. Yu's excited and trembling voice came:
"Okay, the electricity has been sent, congratulations, Mr. Ren!"

"It's all thanks to Mr. Yu's solid and comprehensive technical work in the early stage of the Beijing-Zhangjiakou high-speed railway, and we have reaped a lot of happiness!" Ren Shuxia heard Mr. Yu's words, and thought of this old electrification engineer who was dedicated to the Beijing-Zhangjiakou high-speed railway. Tired She was admitted to the hospital, but even so, he was still concerned about the frontline scene all the time. The technical documents about the Beijing-Zhangjiakou high-speed railway that Mr. Yu had sent her appeared in her mind, and she couldn't help but choked up and said.

"Take care, Mr. Ren! It's cold here, you're a woman, remember to wear thicker clothes!" Mr. Yu was like an old man, caring for Ren Shuxia very much.

"Understood, Mr. Yu, you can recuperate at ease!" Ren Shuxia replied gratefully.

At this time, BJ is approaching the Mid-Autumn Festival, and the wind that blows at night also smells like the northern autumn wind sweeping fallen leaves. Ren Shuxia stands alone at the construction site of the Beijing-Zhangjiakou high-speed railway, her eyes are watching the golden lights in the distance. She couldn't help but have mixed feelings in her heart, thinking of the hardships of her parents and her long life experience in the electrified railway for more than ten years. Although she has gained happiness in work and life, the long night, the two places The separated family life made her feel apologetic to Li Te, as well as deep guilt towards her parents and Ke Ke...

However, when she thought of the Chinese high-speed railways that she personally participated in the construction of, and those passengers who were full of smiles and admired all the way, she couldn't help but feel a warm sense of pride in her heart, because she is an electrified As a descendant of engineers, she should carry the banner of electrification, face the cold wind, and continue to follow the road of electrified railway construction of her fathers...
