發(fā)電機(jī)在我們的日常生活中必不可少，很多人雖然知道發(fā)電機(jī)，但是對發(fā)電機(jī)的原理及常見故障了解不多。下面，我們來看下，燃?xì)獍l(fā)電機(jī)組的工作原理及常見故障分析。
Generators are indispensable in our daily life. Although many people know about generators, they do not know much about their principles and common faults. Next, let's take a look at the working principle and common fault analysis of the gas generator set.
1、發(fā)電機(jī)過熱
1. Generator overheating
（1）發(fā)電機(jī)未按規(guī)定的技術(shù)條件運(yùn)行，如定子電壓過高，鐵損增加；當(dāng)負(fù)載電流過大時，定子繞組的銅損耗變大，監(jiān)測儀器的指示器應(yīng)檢查是否正常。
(1) The generator does not operate according to the specified technical conditions, such as excessive stator voltage and increased iron loss; When the load current is too large, the copper loss of the stator winding becomes larger, and the indicator of the monitoring instrument should be checked for normality.
（2）進(jìn)風(fēng)口溫度過高或進(jìn)水溫度過高，使冷卻器堵塞。應(yīng)降低空氣或進(jìn)水溫度，清除冷卻器內(nèi)的堵塞。限制發(fā)電機(jī)的負(fù)荷，降低發(fā)電機(jī)的溫度，直到故障消除。
(2) The cooler is blocked due to too high air inlet temperature or too high water inlet temperature. The air or water inlet temperature shall be reduced to remove the blockage in the cooler. Limit the load of the generator and reduce the temperature of the generator until the fault is eliminated.
（3）軸承潤滑脂過多或過少，潤滑脂應(yīng)按規(guī)定添加，通常為軸承腔的1/2~1/3（上限為低速，下限為高速），且不超過軸承腔的70％為宜。
(3) If the bearing grease is too much or too little, the grease should be added as required, usually 1/2~1/3 of the bearing cavity (upper limit is low speed, lower limit is high speed), and should not exceed 70% of the bearing cavity.
燃?xì)獍l(fā)電機(jī)組
2、發(fā)電機(jī)啟動后，電壓不能升高
2. The voltage cannot rise after the generator is started
（1）勵磁回路斷路，使電壓上升不起來。應(yīng)檢查勵磁回路有無斷線和接觸良好。
(1) The excitation circuit is open circuit, so that the voltage cannot rise. Check whether the excitation circuit is disconnected and in good contact.
（2）剩磁消失。如果勵磁電壓表上沒有指示，剩磁消失。勵磁器應(yīng)該磁化。
(2) The remanence disappears. If there is no indication on the excitation voltmeter, the remanence disappears. The exciter should be magnetized.
（3）勵磁機(jī)磁場線圈接極性相反，其正負(fù)連接線應(yīng)互換。
(3) The field coil of exciter has opposite polarity, and its positive and negative connecting wires shall be interchanged.
（4）發(fā)電機(jī)檢修時，誤接通磁場線圈使直流電反向，導(dǎo)致殘余磁消失或反向，應(yīng)重新磁化。
(4) When the generator is overhauled, the magnetic field coil is wrongly connected to reverse the DC current, resulting in the disappearance or reverse of the residual magnetism, which should be re magnetized.
3、發(fā)電機(jī)電流過大
3. Excessive generator current
（1）負(fù)荷過大，應(yīng)減少負(fù)荷。
(1) If the load is too large, reduce the load.
（2）輸電線路發(fā)生相間短路或接地故障時，應(yīng)進(jìn)行修復(fù)，排除故障后恢復(fù)正常。
(2) In case of phase to phase short circuit or grounding fault of the transmission line, it shall be repaired, and the fault shall be eliminated before it returns to normal.
4、發(fā)電機(jī)端電壓過高
4. Generator terminal voltage is too high
（1）發(fā)電機(jī)并網(wǎng)供電電網(wǎng)電壓過高，應(yīng)降低發(fā)電機(jī)并網(wǎng)供電電壓。
(1) If the grid voltage of generator grid connected power supply is too high, the grid connected power supply voltage of generator shall be reduced.
（2）如果勵磁裝置故障導(dǎo)致過勵磁，應(yīng)及時檢修勵磁裝置。
(2) If overexcitation is caused by the fault of excitation device, the excitation device shall be repaired in time.
