"Dentsu"!
The "progress bar" refreshes again
The reporter learned from Tianjin Rail Transit Group that on the evening of April 10, as the first urban (suburban) railway in Tianjin, the first section of the Jinjing urban (suburban) railway project was successfully powered by 35kV ring network cable and substation substation at one time, and the goal of "electric communication" of the whole line was successfully completed.
"Dentong" is an important node in the construction of the municipal railway, and the successful power transmission is equivalent to injecting fresh "blood" into the "main artery" of the municipal railway, laying a solid foundation for the subsequent power debugging and realization of the whole line of power lighting, ventilation and air conditioning, water supply and drainage, escalator and other equipment systems, and also providing a strong guarantee for the catenary power transmission, train thermal slip test, comprehensive joint commissioning, trial operation and other stages.
Xu Xiaozhou, equipment engineer of the third project management department of the subway group affiliated to Tianjin Rail Transit Group, told reporters that the traction substation is equivalent to the "heart" of the traction power supply system. The group united all participating units to scientifically organize and carefully deploy, held special promotion meetings for power transmission for many times, clarified responsibilities, implemented the division of labor, and successively carried out many inspections of power transmission conditions to ensure that the power receiving equipment was in a normal state. Before power transmission, the whole line is inspected and cleared in sections synchronously. During the power transmission process, the staff was on duty at each important point, and operated safely, meticulously and orderly to ensure the success of the one-time power transmission.
Up to now, the main structure and track-laying project of the first section of the Jinjing Municipal (Suburban) Railway have been completed, 71% of the equipment installation has been completed, and 62% of the decoration has been completed.
The relevant person in charge said that in the future, the metro group affiliated to Tianjin Rail Transit Group will continue to strictly control the quality of the project, strictly grasp the safety of production, make every effort to speed up the construction of the project, ensure that the line will be opened on schedule within the year, and help realize the rapid access of Tianjin's peripheral new city, external hub and city center.
