For xian fan who lives in Nanshan and Bao'an, line 1 and 11 are crowded every day. A commute time of 1 hour is a winner in life. However, it is expected that after the trial operation of this subway line within this year, it will be more convenient for friends to travel to work.
It is the subway line 12 known as the "Purple Xia Fairy". Recently, Line 12 has made new progress! Recently, Metro Line 12 first adjustment section hot slip test round! full! finish! Yes!
This marks the official launch of the joint commissioning of the equipment system with driving scheduling as the main line of the whole line, laying a solid foundation for the line to achieve the goal of high-quality opening and trial operation within the year.
The hot slip test of the first tuning section was successfully completed
Presumably, many old fans know that the first start of each subway line train after it is electrified should be dedicated to "hot slip", rather than the day when the passengers are officially operated.
What is "hot slip"?
In the hot slip test of the first adjustment section, the subway train departed from the Airport East Depot of Line 12 and traveled along the exit section to Shangchuan Station, ending at Huangtian Station, a one-way 10.9 km.
Through the hot slip test, the power supply, catenary, track, equipment and other systems are inspected, and the vehicle flow collection and pantograph network relationship are analyzed.
In order to fully carry out the hot slip test, the train will run back and forth from the left and right lines at low speed (not more than 20 km / h), medium speed (not more than 40 km / h), and high speed (60-80 km / h), respectively, with a total mileage of about 65 km and a maximum operating speed of 80 km / h.
A total of working groups such as safety supervision, joint dispatch room, technical support, commissioning and cooperation have been set up in this hot slide, and the close cooperation between each group and the division of labor are clear-
- Technical and commissioning team: confirm the hot slip conditions in advance, and confirm 13 main control conditions and 6 basic conditions to ensure the stability of driving power supply and road safety.
- Communication support group: The installation and commissioning of the 800M dedicated wireless system was completed 20 days in advance to ensure smooth hot-slip communication.
- Safety Supervision Group: Strictly check the safety and boundary restrictions of the first adjustment section and the closure of the rail area, prevent personnel from entering the rail area during the hot sliding period, and ensure the personal safety of the participants.
