概述对于电传动内燃机车的柴油机调节应满足以下条件: ——保持确定的转速; ——调整每个规定转速下的负荷以获得适当的输出功率并避免超负荷; ——在增压柴油机上为防止产生过量废气而在负荷变化增加供油量时限制其突然增速。H25型调速器具备以上条件并且它的全部必须的辅助装置都是组装在一个壳体内。只有当伺服马达调节发电机励磁的磁场电阻时,由于伺服马达必须与磁场电阻联在一起,所以它和调速器是分开装配的。因此,调速器和伺服 Overview Diesel engines for electrically driven diesel locomotives should meet the following conditions: - maintain a defined speed; - adjust the load at each specified speed to obtain the appropriate output power and avoid overload; - on a turbocharged diesel engine, Prevent excessive exhaust gas and limit its sudden increase in load as fuel load increases. H25-type governor with the above conditions and all of its necessary auxiliary devices are assembled in a housing. Only when the servomotor adjusts the magnetic field resistance of the generator excitation, it is assembled separately from the governor since the servomotor must be coupled with the magnetic field resistance. So governor and servo
