工作在发电机状态的起动-发电机,当它的转子转速及负荷变化时,是用电压调整器来维持其规定的电压精度。在内燃机车上已获得广泛应用的是TPH-1型振动式电压调整器。此种调压器的工作原理是当发电机转速及负荷变化时,改变其励磁绕组回路中的电阻。由于此种调压器中存在活动元件,并且触头不停地断开与闭合,因而 A starter-generator, working in the generator state, uses a voltage regulator to maintain its regulated voltage accuracy as its rotor speed and load change. Has been widely used in diesel locomotive is the TPH-1-type vibration voltage regulator. The working principle of this regulator is when the generator speed and load changes, change the excitation winding loop resistance. Due to the presence of moving elements in such voltage regulators, and the contacts are constantly open and closed, thus
