1台H30-30型林德叉车配置珀金斯发动机。该机点火开关接通后,充电指示灯能正常发亮,当发动机启动后,该灯理应随着发电机正常充电而熄灭,但该灯仍然长亮。充电指示灯长亮故障的原因可能有:发电机定子绕组短路或开路;整流桥损坏;电压调节器失效;转子励磁绕组异常;充电指示灯线路短路。采用灯泡作充电指示的常见充电电路原理如图1所示。接通点火开关SW后,电源分2路供电,一路
1 H30-30 Linde forklifts configuration Perkins engine. The ignition switch is turned on, the charging indicator light can be normal, when the engine starts, the light should be normal with the generator charging and extinguished, but the light is still bright. Charging indicator light long fault may be due to reasons: generator stator winding short circuit or open; rectifier bridge damage; voltage regulator failure; rotor excitation winding abnormalities; charging indicator light line short circuit. The use of bulbs for charging instructions common charging circuit shown in Figure 1. Turn on the ignition switch SW, the power sub-2-way power supply, all the way
