【正文】 ,速度的提高,以及有力和可靠的操作過載能力成為其主要優(yōu)勢,但不污染環(huán)境,所以特別適用于繁忙的鐵路運(yùn)輸和隧道,以及斜坡的山區(qū)鐵路。但是,在電力機(jī)車上使 用的字符串仍然是直流電動(dòng)機(jī)(這是最大的優(yōu)勢:調(diào)速簡單,只需改變電機(jī)端電壓,因此就可以很容易地實(shí)現(xiàn)在較大范圍內(nèi)的機(jī)車速度,但這種電機(jī)由于需要使用換向器,制造和維護(hù)是非常復(fù)雜的,體積更大),這樣,交流到直流機(jī)車的轉(zhuǎn)變?nèi)蝿?wù)完成。德國制造的電力機(jī)車 E120 就是這種機(jī)車。 目前機(jī)車接觸網(wǎng)供電系統(tǒng),分為直 流系統(tǒng)和交流兩個(gè)(交流系統(tǒng)包括單相交流,三相交流),其中要求電源標(biāo)準(zhǔn)。日本,法國,西德有超過 10000 公里的電氣化鐵路。 中國的電力機(jī)車: 韶山 I 型電力機(jī)車是我國最早使用的電力機(jī)車。 1994 年已成功地發(fā)展了速度達(dá) 160 公里的高速電力機(jī)車以及其他 4 軸電力機(jī)車。 所以Н 60 電力機(jī)車是一個(gè)大膽的技術(shù)改造,這相當(dāng)于 78 個(gè)重大變化。s threephase AC electric lootive created a 210 km per hour highspeed recording. Electric lootive of development depends on the development of electrified railway. Build a real sense electrified railway is first necessary to resolve how to provide highvoltage, change standard power supply problems. Catenary lootive current supply system, divided into DC system and the exchange of two (AC system in the singlephase AC again, threephase AC), which called power supply standard. The frequency of the singlephase AC system to promote the development of electrified railway. 20 in the early 1970s, continental Europe and Japan in Asia is basically realized transport busy main railway electrification. 1973 ~ 1974 outbreak of the oil crisis, the national electricity and internal bustion of the railway traction reevaluation of the economic, favored by the more electric traction. Britain is the development of the original diesel traction, but also started to attach importance to the development of electric traction. Even pletely internal bustion of the United States, the voice of railway electrification also high. To the early 1980s, the world had more than 50 countries and regions to build the electrified railway, the Soviet Union39。s electric lootive began in 1958. At that time, the Ministry of Railways San lootive factory, which is now the Zhuzhou Electric Lootive Factory in assisting the Xiangtan Electrical mining electric lootive manufacturing plant at the same time, design and Preparation railway electric lootive. Early 1958, the Ministry of Machinery Industry organized by the Department of the first mission to the Soviet Union study tour. At that time, the basic stereotypes of the Soviet Union is the use of 20 kV singlephase AC system Н60 frequency electric lootive, and China decided to adopt the 25 kV singlephase AC system frequency vary, so Н60 electric lootive on a bold technological transformation, which amounted to 78 major changes. December 28,1958, China39。s earliest use of electric lootive
