機(jī)械外文翻譯--世界電力機(jī)車的發(fā)展(完整版)
【正文】 in 1914, is the use of the Fushun Coal Mine 1500 V DC electric lootive. 1958 China has successfully produced the first electric lootive, from the ignition of a rectifier to silicon rectifier, lootives constantly improve and enhance performance, to 1976 lmade Shaoshan (SS1 type) No. 131, has been basically established. The deadline for the cessation of production in 1989, SSl electric lootive has a total of 926 Taiwan manufacturers to bee China39。 The Development of World Electric Lootive Electric lootive itself with the original motive accept catenary sent by the current as a source of energy, from lootive traction motor drive the wheels. With electric lootive power, thermal efficiency, fast, strong and reliable operation Guozainaili major advantages, but do not pollute the environment, and particularly applicable to the busy railway transportation and tunnels, the slope of the mountain railway. Electric lootive from the contact line access to electricity, catenary power supply current lootives are both DC and AC. The current system different, not with the electric lootive, can be divided into basically straightDC electric lootive, the TACDC electric lootive, the TACDirectAC electric lootive three. StraightDC electric lootive using DC power supply system, traction substation equipped with rectifier devices, it will bee a threephase AC DC, and then to access the Inter. Therefore, the electric lootive can be made online directly from the contact supply DC Series traction motor use, which simplifies the lootive equipment. DC system39。 發(fā)展我國電力機(jī)車始于 1958 年。 1966 列 SS2 機(jī)車于 1978 年研制成功。在這個時候，半導(dǎo)體技術(shù)和計算機(jī)控制技術(shù)的突破，促進(jìn)發(fā)展催生了新的電力機(jī)車。 1973 年至 1974 年爆發(fā)的石油危機(jī)，重新評估的經(jīng)濟(jì)指標(biāo)是國家電力和內(nèi)燃牽引的鐵路，更青睞電力牽引。 1881年，法國巴黎架設(shè)第一電力架空線 電車線，它的升級，為使用高功率牽引電機(jī)創(chuàng)造條件： 1895 年，美國巴爾的摩 俄亥俄州之間的 公里長的隧道部分直流電氣化鐵路建設(shè)成功。 交 直 交流，交流非電力機(jī)車牽引電機(jī)換向器（即三相異步電動機(jī)），其在汽車制造，性能，功能，大小，重 量，成本以及維護(hù)性和可靠性等方面比換向器容易得多。因此，電力機(jī)車可直接從網(wǎng)上聯(lián)絡(luò)供應(yīng) DC 系列直流牽引電動機(jī)使用，簡化了機(jī)車設(shè)備。 電力機(jī)車從接觸線獲得電力，接觸網(wǎng)供電電流機(jī)車都是直流和交流。 接觸網(wǎng)系統(tǒng)的直流電壓沒有提高很多。 電力機(jī)車的工作原理：目前的接觸線和電力機(jī)車經(jīng)過拱形后后重新進(jìn)入斷路器后，主變壓器，交流牽引從主變壓器繞組通過硅整流單位，分成兩組，六個平行對牽引電機(jī)直流電源集中到牽引電動機(jī)的扭矩，機(jī)械能變成電能通過傳動齒輪驅(qū)動的機(jī)車驅(qū)動車輪轉(zhuǎn)動。單相交流系統(tǒng)促進(jìn)發(fā)展電氣化鐵路。目前，世界電氣化鐵路已達(dá)到 20 多萬公里。始于 1914年，是應(yīng)用于撫順煤礦的 1500 V 直流電力機(jī)車。 伴隨著世界潮流，誕生了新的“直 交”電力機(jī)車技術(shù)。 1958 年 12 月 28 日 ，我國第一臺電力機(jī)車研制成功的鐵路干線 ,命名“ Y16” ,機(jī)車持續(xù)功率 3410 千瓦，最高速度 100 公里 /小時。s total length of electrified railway reached over 40,000 kilometers, Japan, France, West Germany have a more t
