【正文】 ed in the development speed of 160 km of highspeed electric lootive, and other 4axis. World track for the new “paydirectdiplomacy” electric lootive new technology, from the late 1970s, China has been carrying out small and mediumsized railway power converter units on the ground and highpower test on the HandDirectAC electric lootive Research has also achieved initial success. Development of China39。s electric lootive: Shaoshan an electric lootive of China39。s electric lootive also pay DC electric lootive. TACDirectexchange by exchange of nonelectric lootive traction motor mutator (that is, threephase asynchronous motors),which is in the motor manufacturing, performance, functionality, size, weight, cost, maintenance and reliability and so on than the motor mutator much easier. It is the failure of the electric lootive, is the main reason for speed rather difficult. This lootive has excellent traction capacity promising. Germanmade electric lootive E120 This is the lootive. The working principle of electric lootive, the current contact wire, and withstand electric lootive into the arch after reentering the circuit breaker after the main transformer, AC traction from the main transformer winding through silicon rectifier units, divided into two groups of six parallel to the traction motor DC supply concentrate to a traction motor torque, the mechanical energy into electric energy through the transmission geardriven lootive drive wheels turning. The development of electric lootives: The first to create the first standard gauge electric lootive is the Scots R Davidson, time is 1842. May 1879, the German Siemens W V design and manufacture of a 18 to pull on the three open passenger electric lootive, this is the first electric lootive successful pilot. 1881, Paris, France at the first of electricity from overhead wires tram lines, which for the upgrade, using highpower traction motors to create the conditions: 1895, the United States in Baltimore Ohio between km long tunnel section DC electrified railway construction. 1903 Germany39。 1999 年 5 月 26 日，我國的株洲電力機(jī)車廠生產(chǎn)了第一個速度超過 200 公里 DDJ1 子彈頭型電力機(jī)車，標(biāo)志著我國電力牽引已躋身于國際高速列車服務(wù)行列。在那個時候，基本定型的觀念是：由于蘇聯(lián)使用 20 千伏單相交流系統(tǒng)Н 60 頻率電力機(jī)車，因此中方?jīng)Q定采取 25 千伏單相交流系統(tǒng)，并且頻率各不相同。在地面上的高功率測試也在進(jìn)行中 ,直 交流電力機(jī)車研究也已取得初步成效。然后又成功繼承發(fā)展 SS5 ， SS6 和 SS7 型電力機(jī)車。直到 1989年停止生產(chǎn)的最后期限， SSL 電力機(jī)車共有 926 家臺灣制造商，成為我國第一個電氣化鐵路主要火車頭。到 20 世紀(jì) 90 年代，歐洲，日本和其他主要摩托車制造商幾乎 停止直流傳動電力機(jī)車的生產(chǎn)，交流電
