东风型机车的电压调整器最早是机械多排振子触点式，由于它出了故障难以修复调整，被当时的锗管晶体管电压调整器所取代。受历史条件的限制，该电路本身的缺陷很多，以致装车后故障频繁，成了东风型机车蓄电池亏电的一个老大难问题。1984年柳园机务段的东风型机车一度出现临修? Dongfeng locomotive voltage regulator is the first mechanical multi-row vibrator contact type, because it is difficult to repair a fault adjustment, was the German transistor transistor voltage regulator replaced. Due to the limitation of historical conditions, many shortcomings of the circuit itself, resulting in frequent failure after loading has become a permanent problem for the loss of battery power of Dongfeng locomotive. Liuyuan locomotive depot in the Dongfeng locomotive once appeared temporary repair?
