The first traction transformer of Jintai railway is in place smoothly
On October 16, a 42 ton "big guy" was running in Pan'an substation of Jintai railway, which was the traction transformer just installed three days ago.
this is the first traction transformer of the whole line of Jintai railway with a total length of 226.12km. Its successful placement marks that the traction substation project of Jintai railway has entered the stage of equipment installation and construction, and also set off the climax of the four power projects of Jintai railway in one hundred days. The four power projects of
Jintai railway are undertaken by the first company of China Railway Electrification Bureau Group Co., Ltd., including communication engineering, power engineering, substation engineering and OCS engineering. A 6031 a 6031 Jintai railway is an electrified railway, and the train itself does not charge, so how does it keep moving forward on the railway? Its electricity comes from the catenary along the railway. The
traction substation is the "heart" of the electrified railway. According to the different requirements of electric traction for current and voltage, it transforms the electric energy sent by the power system into the electric energy suitable for electric traction, and then respectively sends it to the overhead contact network set up along the railway line to supply power for the electric locomotive. There are four traction substations in the whole line of
Jintai railway, including Pan'an, Xianju, Duqiao and linhainan. Each traction substation has two traction transformers, which are the core equipment of the whole traction power supply system.
the traction transformer in place this time has a net weight of 42 tons and a capacity of 25000 kilowatt ampere. After being electrified, it will supply power for the Wuyi Xianju section of Jintai railway.
because of its large volume and weight, the transportation process of traction transformer is required to be stable and collision proof. It also has strict requirements for site construction and site conditions. In order to ensure the smooth installation of the transformer, the construction team of Jintai railway carefully planned, formulated a special construction scheme, and conducted safety technical disclosure to the construction personnel to ensure the smooth completion of the transformer installation. On the day of installation of
, the transformer was placed on the sleeper, and the bottom was supported by 90cm wood plate. The transformer could only be lowered by 5cm each time through hydraulic method construction. After seven or eight times of "plate removal base plate" cyclic commissioning, the transformer finally landed stably on the basis of the transformer and successfully put in place. The
Jintai railway is the first self built electrified railway in our province. After the completion of the project, it will become a large passenger and freight corridor in the Middle East of Zhejiang Province, which will be opened to traffic next year as planned.
