1.前言近几年,随着铁道通勤网的扩大,为了更有效地提高运输能力,城市近郊的铁道运输不只是要采用长大编组和提高车流密度的方法,而且要增加适应提高运输能力要求的经济的、性能好的车辆。其中,具有优越特性的励磁斩波车越来越多地作为市郊电车使用了。它加减速快,高速时节能效果显著,并且制造成本也比电枢斩波车便宜。另一方面,由于半导体技术的进展,耐高压、大电流的控制极可关断晶闸管(GTO晶闸管)已能够用于车辆上了。使用GTO晶闸管的励磁斩波装置,已装在京浜电动车组800型车上投入营业运行,现介绍其特点和性能。 2.研究的经过水公司59年以来,常用复激电动机再生制动的控制装置。69年研究了使用反相阻断晶闸管的励磁斩波装置,至今装车数量约
1. Introduction In recent years, with the expansion of the railway commuter network, in order to improve the transportation capacity more effectively, the railway transportation in the outskirts of the city not only adopts the method of growing up and increasing the traffic density, but also increases the requirements of adapting and improving the transportation capacity The economy, good performance vehicles. Among them, the superior characteristics of the excitation chopper car more and more used as a suburban tram. It is fast acceleration and deceleration, energy-saving effect is remarkable at high speed, and the manufacturing cost cheaper than the armature chopper. On the other hand, high-voltage, high-current controlled turn-off thyristors (GTO thyristors) have been used in vehicles due to advances in semiconductor technology. Excitation chopper device using GTO thyristor, has been installed in Keihin Electric Vehicle 800 models put into operation, is now introduced its characteristics and performance. 2. After studying the water company 59 years, the common regenerative motor regenerative braking control device. 69 years to study the use of reverse-phase blocking thyristor exciting chopper device, the number of cars loaded so far
