SS9型電力機(jī)車畢業(yè)論文

摘    要
隨著電力機(jī)車技術(shù)的發(fā)展，機(jī)車控制系統(tǒng)性能的好壞越來越受到廣泛的關(guān)注。因?yàn)椋瑱C(jī)車控制系統(tǒng)性能的好壞在很大程度上影響著機(jī)車性能的好壞，從而影響列車運(yùn)行的安全性和可靠性。
SS9型電力機(jī)車作為我國自主研制的新型電力機(jī)車，采用了許多國際客運(yùn)機(jī)車先進(jìn)技術(shù)，最高構(gòu)造時(shí)速達(dá)170km/h，滿足了在長距離區(qū)間、長大坡道上牽引大編組旅客列車運(yùn)行的需要。通過對(duì)SS9型電力機(jī)車主電路、輔助電路結(jié)構(gòu)的研究及其運(yùn)行工況的探討，使我們可以很好的了解該機(jī)車的性能，為以后更多快速運(yùn)行列車工作狀況的學(xué)習(xí)以及交流傳動(dòng)電力機(jī)車的研究作鋪墊。
本論文首先針對(duì)SS9型電力機(jī)車的基本特性做了一定的介紹，再結(jié)合相關(guān)的理論基礎(chǔ)對(duì)該機(jī)車的主電路、輔助電路做了詳細(xì)的研究。最后分析了SS9型電力機(jī)車的牽引、制動(dòng)工況。作為SS9型電力機(jī)車上一個(gè)至關(guān)重要的部分－LCU邏輯控制單元，我們也對(duì)其基本結(jié)構(gòu)和功能做了簡單的介紹。

Abstract
With the electric locomotive technology, locomotive control system performance is good or bad more and more attention. Because the locomotive control system performance is good or bad to a large extent affect locomotive performance is good or bad, thus affecting the safety of train operation and reliability.
SS9 electric locomotive, as China has independently developed a new type of electric locomotives, using many advanced technologies the international passenger locomotive, the maximum structural speed of 170km / h, met in the long interval, a large grouping of growing up the ramp on the traction needed to run passenger trains. By SS9 electric locomotive circuit, auxiliary circuit structure and its operating conditions of, so that we can well understand the performance of the locomotive, running trains for the future working conditions for more rapid learning and the AC drive electric locomotives research for bedding.
    This paper first SS9 electric locomotive for the basic characteristics of some description to do, combined with the theoretical basis of the relevant main circuit of the locomotive, the auxiliary circuit to do a detailed study. Finally the SS9 electric locomotive traction and braking conditions. SS9 electric locomotive as a vital part-LCU logic control unit, we have to do its basic structure and function of a simple introduction.
Keywords: electric locomotive; the main circuit; auxiliary circuit; LCU logic control unit; operating conditions
