| The auxiliary system is the diesel locomotive important constituent, its performance quality directly affects the locomotive the efficiency, the reliability. Presently, the countries all in unceasingly improve and develop the new auxiliary drive, reduce the assistance power the consumption, and enhance the entire vehicle the efficiency. At the same time, also unceasingly enhance the auxiliary system the reliability, in order to guarantees the entire vehicle the safe operation. Our country diesel locomotive auxiliary transmission system uses the mechanical drive, the partial locomotive attempt to use the exchange auxiliary transmission. Therefore, it is necessary to clearly recognize our country current diesel locomotive auxiliary transmission system the present situation and the development direction, formulate the feasible measures, gradually impel our country diesel locomotive auxiliary transmission system the development, thus enhances our country diesel locomotive the utilization performance.Using the AC auxiliary transmission system is the locomotive technological development direction and the tidal current, and has the extremely obvious superiority. The our country diesel locomotive AC auxiliary transmission system has the quite mature technology and the product foundation, and has met the application requirement, expecting to obtain the promotion soon.By taking the HXN3diesel locomotive imported from EMD corporation of USA by the Dloco as an example,this paper gives the specific introduction and research on the total status instructions, main and auxiliary generator composing, AC traction excitation, battery charging, diesel engine starting and so on. |
