In view of the direct maintenance of the generator fault of the gas generator set, today, we will simply analyze the fault of the generator system to prevent the emergency.

　　一般充电系统的常见故障有不充电、充电电流过大、过小、不稳定等。

　　The common faults of the general charging system are non charging, charging current is too large, too small, unstable, etc.

　　1、故障现象：不充电

　　1. Fault phenomenon: no charging

　　当bat365官方网站登录以中速运行时，电流表指示放电或充电指示灯亮。

　　When the generator is running at medium speed, the ammeter indicates discharge or charging.

　　故障的原因

　　Cause of failure

　　（1）充电系统的连接线短路。

　　(1) The connection wire of the charging system is short circuited.

　　(2)皮带因过度磨损、松弛而打滑

　　(2) Belt slipping due to excessive wear and looseness（3）调节器失灵;如低速电氧化，正常闭合;高速触点相互接触;不良的搭接或弹簧弹簧弹性减弱，调节电压值低于电池的电动势。

　　(3) The regulator fails; such as low-speed electric oxidation, normal closing; high-speed contacts contact each other; poor lap or spring spring elasticity weakening, and the regulating voltage value is lower than the electromotive force of the battery.

　　(4)bat365官方网站登录内部故障，如定子三相绕组之间短路或铁块故障;电刷卡在刷框内，无法与滑环等接触，导致bat365官方网站登录不能发电。当检测到故障时，可以按照以下步骤进行检查:

　　(4) Internal faults of the generator, such as short circuit between three-phase windings of the stator or iron block fault; the brush is stuck in the brush frame, unable to contact with the slip ring, etc., resulting in the generator unable to generate electricity. When a fault is detected, it can be checked as follows:

　　(1)检查充电系统接线是否可靠。

　　(1) Check whether the charging system wiring is reliable.

　　（2）检查皮带是否放松，判断方法可采用拇指压带中点，挠度约10mm为宜。如果放松，皮带可以张紧或更换一个新的皮带。

　　(2) Check whether the belt is loosened. The judgment method can be the middle point of thumb pressure belt, and the deflection is about 10 mm. If relaxed, the belt can be tensioned or replaced with a new one.

　　(3)检查充电电路、励磁电路是否损坏。可以用万用表或试验灯，整体后用局部方法找出断口，然后排除。

　　(3) Check whether the charging circuit and excitation circuit are damaged. A multimeter or test lamp can be used to find out the fracture by local method after the whole and then eliminate it.

　　（4）确定bat365官方网站登录或调节器的故障。用电线连接稳压器上的“+”和“F”端子，然后启动发动机，运行它，观察电流表。如果显示充电，则表明bat365官方网站登录工作正常，故障在调节器。如果电流表仍显示放电，或充电指示灯仍未熄灭，则bat365官方网站登录不充电。

　　(4) Determine the problem with the generator or regulator. Connect the "+" and "F" terminals on the voltage regulator with wires, then start the engine, run it and observe the ammeter. If charging is indicated, the generator is working normally and the fault is in the regulator. If the ammeter still shows a discharge, or if the charge indicator is not off, the generator will not charge.

　　二、故障现象:充电电流太小

　　2、 Fault phenomenon: charging current is too small当发动机以中速运行时，电流表指示充电电流太小。当连接大功率的前照灯或电气设备时，电流表显示充电电流进一步减小或放电。

　　When the engine is running at medium speed, the ammeter indicates that the charging current is too small. When a high-power headlamp or electrical equipment is connected, the ammeter indicates that the charging current is further reduced or discharged.

　　2)故障的原因

　　2) Cause of failure

　　(1)传动带松弛而造成打滑。

　　(1) The drive belt is loose causing slippage.

　　(2)充电线接线不良。

　　(2) The charging wire is poorly wired.

　　（3）这台交流bat365官方网站登录内部有故障。定子绕组有相位连接不良或断开;电刷磨损过多，弹簧弹性减弱，使电刷与滑环接触不好。

　　(3) There is an internal fault in this alternator. The stator winding has poor phase connection or disconnection; the brush is worn too much and the spring elasticity is weakened, which makes the brush and slip ring contact poorly.

　　（4）调节器出了问题。如低速触电氧化不良接触;弹簧弹性力降低，调节电压过低三、故障现象:充电电流过大当bat365官方网站登录以中速运行时，电流表指示大电流充电(大于30A)，电池电解液消耗过快，bat365官方网站登录容易过热，灯泡容易烧坏等。

　　(4) There is something wrong with the regulator. For example, the low-speed electric shock oxidizes the poor contact; the spring elastic force reduces, the regulating voltage is too low. 3. The fault phenomenon: the charging current is too large. When the generator is running at medium speed, the ammeter indicates the high current to charge (more than 30a), the battery electrolyte consumption is too fast, the generator is easy to overheat, and the lamp bubble is easy to burn.
