  1. Speed controls for traction include not only electrical vehicles of horizontal transportation such as electrical trains, internal - combustion locomotives with electrical transmissions, underground metros, light fait locomotives, trolley buses, even magnetic suspension trains and electrical cars etc., but also electrical vertical traction systems such as elevators, automatic moving staircases, mine winding engines, and gantry crane trucks etc

    牽引調速既包括電氣火車、電傳動的內燃機車、地下鐵道、輕軌機車、無軌電車及磁懸浮列車和電動汽車等這類水平運輸電動車輛，也包括電梯、自動電梯、礦井卷揚機和龍門吊車等電動豎直牽引系統。
  2. At present, differential protection is often used as the main protection for traction transformers. however, the existing of certain factors, such as magnetizing inrush, over - excitation, ct saturation and mismatching of ct ratio, will result in that it is hard to distinguish state current and fault current, and differential protection misoperation or maloperation, then secure operation of electric railways system will be threatened

    目前，牽引變壓器通常採用差動保護作為主保護，但是在某些因數的影響下差動保護並不能準確的區分牽引變壓器內部故障或非內部故障，如故障電流與變壓器處于勵磁涌流、過勵磁， ct飽和及ct變比不匹配等情況下的狀態電流就很難準確的區分，可能造成保護誤動或拒動，從而危及整個鐵道電氣化系統的安全運行。
  3. Company development and production of products mainly include : industrial control and monitoring, dc converter, exchange converter, permanent magnet motor, power generation electronic control system, various industrial control module, railway traction systems and urban transport systems

    公司研發及生產的產品主要有：工業控制及監測、直流變流器、交流變流器、永磁電機、電力發電電控系統、各種工業控制模塊、鐵路牽引系統和城市交通系統等。
  4. The main achievements of the thesis are as follows : ( 1 ) kinds of techniques to detect magnetizing inrush of traction transformers are thoroughly investigated in this paper, and their limitation are indicated and corresponding improvement techniques are proposed. ( 2 ) in this paper, flux linkage equilibriun equations are used to build " ash - box " models of some traction transformers based on system identification, such as two - winding single - phase traction transformer, impedance - matching equilibriun traction transformer and scott traction transformer

    論文的主要內容有： （ 1 ）詳盡分析了現有的針對牽引變壓器勵磁涌流演算法的保護演算法，提出了每種演算法的局限性及其改進方法； （ 2 ）提出適用於鐵道電氣化系統中各種牽引變壓器對應的三?二相轉換規則，利用該規則可將對應量的轉換置於保護軟體中，從而可大大減輕在牽引變壓器兩端外部復雜的接線。
  5. Once the force between wheel and track surpasses the biggest adhesive power that the track ’ s permission, it will bring the idle turn and slide of wheels and the vehicles can ’ t be droved or braked. therefore the traditional metro system is a kind of driving type that is restricted with the track adherence

    由直線感應電動機驅動的線性地鐵是目前發展比較快的城市軌道交通工具之一，其牽引力不再受到輪軌黏著的限制，而是靠直線電機初級與次級之間的電磁推力驅動運行。
