發電機充電不穩故障原因與排除——Generator charging instability fault causes and troubleshooting

 

 (1)發電機充電不穩故障現象

發動機在意速以上運轉時，電流錶指示不穩或開燈後又閃亮現象

(2)發電機充電不穩原因分析

1)轉動帶鬆動有時打滑，

2) 充電系導線接觸不良

3) 發電機故障:①轉子或定子線圈有局部斷路或短路故障。②電刷與滑環間基礎不良

4) 調節器調節觸點燒蝕或髒汙，觸點臂彈簧過軟等.

 

(3)發電機充電不穩故障診斷方法步驟

1)首先排除傳動帶打滑和導線基礎不良等外在故障。

2) 應先檢查調節器的故障再檢查發電機的故障。

3)發電機故障:@軸承故障，①轉子與定子相碰，電刷磨損過大或與滑環接觸不良，②轉子軸彎曲等

(1) generator charging instability fault phenomenon

When the engine is running at or above the intentional speed, the ammeter indication is unstable or the light is on and then flashing

(2)Analysis of the causes of unstable charging of the generator

1) Loose rotating belt sometimes slipping.

2) Poor contact of charging system cable

3) Generator failure.

① Rotor or stator coil has a local break or short circuit fault. 4) regulator regulating contact erosion or dirty, contact arm spring too soft, etc.

(3) generator charging instability fault diagnosis method steps

1) Firstly, exclude external faults such as slippage of the drive belt and poor base of the lead wire.

2) Check the fault of the regulator before checking the fault of the generator.

3) Generator fault:@ Bearing fault, ① Rotor and stator touching each other, brush wear too much or poor contact with slip ring, ② Rotor shaft bending, etc.
