白俄罗斯铁路运输工程学院为3型内燃机车研究出无触点全工况的程序控制功率调节器。它能保证司机控制器的16个档位均能充分利用柴油机的功率。并且,在部分负荷上,柴油机按照经济特性曲线工作。此外,该调节器的线路还能限制主发电机的电流和电压。该电流、电压和功率调节系统的确立代替了APM(功率自动调整装置)和APT(电流自动调整装置)的测速发电机线路。调整器和 The Belarusian Institute of Railway Transport Engineering developed a program-controlled power conditioner for all 3-type diesel locomotives with non-contact full-scale operating conditions. It ensures that all 16 gears of the driver’s controller take full advantage of the diesel engine’s power. And, at part load, the diesel engine operates according to the economic characteristic curve. In addition, the regulator’s wiring also limits the current and voltage of the main generator. The establishment of the current, voltage and power regulation system replaced the tachometer generator lines of the APM (Automatic Power Adjustment) and the APT (Current Automatic Adjustment).
