The Design And Research Of Electric System On Qingzang Coach

Qingzang coach is a train which is first used in Qingzang plateau. The altitude of the plateau even mounted at 5000 km. Its special geography envioroment and bad climate condition has been considered during design and manufacture. In order to make the train run saftly on the plateau, Many tests have been done in the Qingzang plateau about the electrical partments and equipments , the qualified products have been chosen. My papar was written after my experience in the design and tests in the plateau and was based on the first Qingzang train manufactured successfully by the Nanche Sifang locomotive and rolling stock company.(1) The geography envioroment and bad climate condition of Qingzang railway have been given in this paper, and put forth the questions in the pratical application and the solution methods have been given.(2) Hardware design about the electry-providing systems /the control systems and network communication systems are specified in the paper. And make a detailed discussion about the the logical control software used in the electrical equipment of train, escpecially in the associate control about aircondition and oxygen providing machine.(3) According the test conclusion of electrical partments used in the train, proper products are chosen in the disign and applied in the qingzang train. Considered about the running safety of train and ride comfort index, I gives the detailed logical control between the relation of synthetic control case/converter/aircondition/oxygen providing machine. And mainly demostrate the control relation between aircondition and oxygen.(4) Improvement is provided after the summarize of first Qingzang train's trial running conclusion .
