目前我国客车主要采用LK_5型车电装置。这套装置没有单独设置稳压电器,而是当列车运行速度达到或超过某一数值后,利用传动皮带的打滑,使发电机的转速维持不变,以保证输出电压的稳定;此外,还利用复式蓄电池组和降压电阻来平缓电压的波动。这种方法的机构简单,运用方便。但是,有哪些因素影响它的电压波动,其稳压品质如何……,都是尚待研究的问题。本文的目的,在于对这些问题作初步的理论分析,找出发电机电压调差率及电灯电压波动率,并探求改善其品质的途径。
At present, China’s main passenger car LK_5-type electric device. The device is not set up a separate regulator, but when the train speed reaches or exceeds a certain value, the use of transmission belt slippage, so that the generator speed remains unchanged in order to ensure the stability of the output voltage; In addition, Multi-battery pack and step-down resistor to smooth voltage fluctuations. The mechanism of this method is simple and easy to use. However, what are the factors that affect its voltage fluctuations and how the regulation quality ... are all problems to be studied. The purpose of this paper is to make a preliminary theoretical analysis of these problems and to find out the generator voltage regulation rate and the lamp voltage fluctuation rate and to explore ways to improve its quality.
