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.

　　一般充電系統(tǒng)的常見故障有不充電、充電電流過大、過小、不穩(wěn)定等。

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

　　1、故障現(xiàn)象：不充電

　　1. Fault phenomenon: no charging

　　當(dāng)發(fā)電機以中速運行時，電流表指示放電或充電指示燈亮。

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

　　故障的原因

　　Cause of failure

　?。?）充電系統(tǒng)的連接線短路。

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

　　(2)皮帶因過度磨損、松弛而打滑

　　(2) Belt slipping due to excessive wear and looseness（3）調(diào)節(jié)器失靈;如低速電氧化，正常閉合;高速觸點相互接觸;不良的搭接或彈簧彈簧彈性減弱，調(diào)節(jié)電壓值低于電池的電動勢。

　　(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)發(fā)電機內(nèi)部故障，如定子三相繞組之間短路或鐵塊故障;電刷卡在刷框內(nèi)，無法與滑環(huán)等接觸，導(dǎo)致發(fā)電機不能發(fā)電。當(dāng)檢測到故障時，可以按照以下步驟進行檢查:

　　(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)檢查充電系統(tǒng)接線是否可靠。

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

　　（2）檢查皮帶是否放松，判斷方法可采用拇指壓帶中點，撓度約10mm為宜。如果放松，皮帶可以張緊或更換一個新的皮帶。

　　(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)檢查充電電路、勵磁電路是否損壞?？梢杂萌f用表或試驗燈，整體后用局部方法找出斷口，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.

　?。?）確定發(fā)電機或調(diào)節(jié)器的故障。用電線連接穩(wěn)壓器上的“+”和“F”端子，然后啟動發(fā)動機，運行它，觀察電流表。如果顯示充電，則表明發(fā)電機工作正常，故障在調(diào)節(jié)器。如果電流表仍顯示放電，或充電指示燈仍未熄滅，則發(fā)電機不充電。

　　(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、故障現(xiàn)象:充電電流太小

　　2、 Fault phenomenon: charging current is too small當(dāng)發(fā)動機以中速運行時，電流表指示充電電流太小。當(dāng)連接大功率的前照燈或電氣設(shè)備時，電流表顯示充電電流進一步減小或放電。

　　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)傳動帶松弛而造成打滑。

　　(1) The drive belt is loose causing slippage.

　　(2)充電線接線不良。

　　(2) The charging wire is poorly wired.

　?。?）這臺交流發(fā)電機內(nèi)部有故障。定子繞組有相位連接不良或斷開;電刷磨損過多，彈簧彈性減弱，使電刷與滑環(huán)接觸不好。

　　(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.

　?。?）調(diào)節(jié)器出了問題。如低速觸電氧化不良接觸;彈簧彈性力降低，調(diào)節(jié)電壓過低三、故障現(xiàn)象:充電電流過大當(dāng)發(fā)電機以中速運行時，電流表指示大電流充電(大于30A)，電池電解液消耗過快，發(fā)電機容易過熱，燈泡容易燒壞等。

　　(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.
