3月29日新聞――龐巴迪公司研發(fā)了世界首個不間斷運行通用列車，運用三個電源轉(zhuǎn)換供電（柴油機，交流電源和直流電源），這是ABB集團變壓器技術(shù)的一大突破。 幾十年來，全世界的鐵路員工都夢想一輛能利用三個電源轉(zhuǎn)換供電的列車，在柴油機電源，交流電源和直流電源間轉(zhuǎn)換簡單易行而有效。 隨著龐巴迪推出AGC XbiBi不間斷運行通用列車（AGC XbiBi代表雙模式和雙電壓式），他們的夢想實現(xiàn)了，這得益于ABB集團生產(chǎn)的車頂牽引變壓器。 之前，牽引變壓器（用交流電源為列車供電）和柴油機是相互排斥的，因為他們裝在列車的相同部位。 重要的是，車頂牽引變壓器不影響列車本身的速度，加速度和列車的內(nèi)部容量。 ABB通過研發(fā)一種可以裝在車頂?shù)臓恳儔浩鞔蚱屏诉@個僵局，因此，柴油機可以被裝在列車內(nèi)部上方。 為SNCF而研發(fā)AGC XbiBi 龐巴迪研發(fā)的AGC XbiBi不間斷運行通用列車用于法國國家鐵路公司SNCF，該公司在二十一個地區(qū)廣闊的網(wǎng)絡(luò)都采用了這三個發(fā)電設(shè)備。 一趟旅程，一輛列車 例如，從Marseille途經(jīng)格勒諾布爾到達日內(nèi)瓦，部分由柴油機供電，部分是交流電源供電，部分是直流電源供電，這就意味著，在AGC XbiBi通用列車推出之前，任何時候，地區(qū)供電系統(tǒng)的改變，比如從柴油機供電到交流電源供電的改變，旅客都需要改乘列車。而推出的AGC XbiBi通用列車使列車可以行使整個旅程無需考慮電源轉(zhuǎn)換的問題。 AGC XbiBi通用列車是基于龐巴迪公司的AGC家族列車研發(fā)的，AGC列車是一個通用的平臺，包括柴油機，柴油機/交流轉(zhuǎn)換和交流/直流轉(zhuǎn)換。龐巴迪目前向SNCF運送612輛AGC列車，ABB為其運送牽引變壓器，柴油機發(fā)電機和新型通勒列車用牽引變壓器。 original text [COLOR=#708090]ABB helps develop the world‘s first universal train 2007-03-29 - Bombardier has developed the world‘s first universal train that can run without stopping on all three power supply alternatives: diesel, AC and DC power – a breakthrough made possible by unique ABB transformer technology. For decades rail operators all over the world have dreamt of a train that could run on all three power alternatives and switch effortlessly and efficiently between diesel, AC and DC power. With the launch by Bombardier of the AGC XBiBi （which stands for bi-mode and dual voltage） that dream has now been realized, thanks to a unique ABB technology – the roof-mounted traction transformer. Previously the traction transformer （which powers the train with AC power） and the diesel engine were mutually exclusive because they occupied the same position in the train. ABB solved the impasse by developing a traction transformer that could be installed on the roof of the train, thereby freeing up space inside for the diesel engine. Crucially, the roof-mounted traction transformer has no impact on the speed, acceleration, performance or seating capacity of the train itself. Developed for SNCF The AGC XBiBi was developed for the French national rail operator SNCF （Société Nationale des Chemins de fer Français）, whose extensive network in 21 regions uses all three power alternatives. Of the 29,500 kilometers of track in the SNCF network, 15,800 km are not electrified, 5,800 km are electrified at 1.5 kV DC and 7,900 km at 25 kV AC. One route, one train A route like Marseille to Geneva via Grenoble, for instance, is part diesel, part AC and part DC, which means that prior to the AGC XBiBi passengers had to change trains whenever the regional power system switched from, say, diesel to AC. With the AGC XBiBi, a single train can now run the entire route, regardless of power system. The AGC XBiBi is based on Bombardier‘s AGC （autorail à grande capacité） family of trains, a versatile platform that consists of diesel, diesel/AC and AC/DC variants. Bombardier is currently delivering 612 AGC trains to SNCF. ABB is supplying the traction motors for all 612 trains, the generators for the diesel variants, and the traction transformers for the AC trains. [/COLOR]
