ss7e型電力機(jī)車電路結(jié)構(gòu)系統(tǒng)研究

1、寧夏理工學(xué)院畢業(yè)論文I摘要為了適應(yīng)我國經(jīng)濟(jì)的高速發(fā)展，鐵路建設(shè)也跟隨著進(jìn)入了高速發(fā)展階段。經(jīng)過幾十年的發(fā)展，我國的電力機(jī)車從最初的韶山1型發(fā)展到了今天的高速動車組。運(yùn)輸能力得到了大幅提高。SS7E型電力機(jī)車具備強(qiáng)大的功率及牽引力，它牽引持續(xù)功率為4800kw，最高速度為170kmh，在全國鐵路大面積提速之際，SS7E型電力機(jī)車滿足國內(nèi)各干線提速需要。本文重點(diǎn)對SS7E型電力機(jī)車電路結(jié)構(gòu)進(jìn)行分析，說明整流調(diào)壓電路的控制過程、三段不等分相控
