D88尊龙側刀閘、起勵電源開關是否均合上。然后再檢查是否有起勵電源,PT保險是否熔斷,PT回路的接線是否松動。

  When the regulator issued a "signal excitation failure", should first check the regulator in in the normal to the excitation before starting state, such as AC and DC power cabinet switch, arc magnetic switch, PT high voltage side switches, excitation power supply switch is closed. Then check whether there is excitation power supply, PT insurance is blown, PT circuit wiring is loose.

  如果這些都正常,就需要另換一個通道起勵。如果能夠正常起勵了那么就說明是調節器通道內的原因;如果還是無法正常起勵,則應當檢查起勵回路、脈沖公共回路、可控硅整流器、轉子回路是否有接地或者短路等。

  If these are normal, you need to change another channel excitation. If the normal excitation so that is why regulator in the channel; if this is not the normal excitation, should check the pulse excitation circuit, public circuit, silicon controlled rectifier, the rotor circuit whether grounding or short circuit etc.

  如果調節器沒有發出“起勵失敗”的信號,但發電機仍然無法自動起勵,那么可以在勵磁盤附近起勵或者遠方人工起勵如果遠近方都無法人工起勵,應當檢查發電機組頻率是否沒有達到45HZ以上。

  If the regulator did not issue a "excitation failure" of the signal, but still can not automatic excitation generator, then the excitation excitation near the disk or remote artificial excitation if the far side could artificial excitation, the frequency generator should check whether there is no more than 45HZ.

D88尊龙  如果勵磁裝置已有勵磁電流輸入發電機勵磁繞組,但機組仍然無法建壓成功,則應當考慮是否存在發電機組起勵電流不夠的問題,可適當調節起勵限流電阻,加大起勵電流進行試驗及檢查。

  If the input excitation device of excitation current generator excitation winding, but the unit still cannot build pressure successfully, you should consider whether there is enough excitation current the problem of generating units, may adjust excitation current limiting resistance, increase of excitation current test and inspection.

D88尊龙  一般來說,很多機器或者設備在平時運行的時候,都會產生一些聲音,這些大部分是機器零件間的碰撞所產生的聲音,但是對于柴油發電機組這個設備來說,在它工作的時候,有的時候會出現噪音,是什么樣的原因導致這個現象出現的呢。首先,噪音是由于空氣氣體與物體相互作用而產生的,造成大氣輻射的空氣動力噪音。空氣動力噪音一般包括進氣噪音,排氣噪音以及冷卻風扇噪音。還有一種情況就是由發電機轉子在電磁場高速旋轉產生的電磁噪音,另外還要兩種就是燃燒噪音和機械噪音,這兩種很相似所以很難分辨。無論柴油機在運行的時候出現噪音的原因是什么,這個時候我們都需要及時的處理好,光纖激光切割機的人士表示只有這樣才能更好的去使用這個機器哦。

D88尊龙  Generally speaking, a lot of machines or equipment in normal operation, will produce some sound, most of these is the collision between machine parts produced by the sound, but for the diesel generator equipment, when it works, when there will be some noise, what is the reason causing this phenomenon it. First, the noise is caused by the interaction between the air and the object, resulting in atmospheric radiation aerodynamic noise. Aerodynamic noise generally includes intake noise, exhaust noise and cooling fan noise. There is a situation by the generator rotor in the electromagnetic field generated by high-speed rotation of the electromagnetic noise, and the other two is the combustion noise and mechanical noise, the two are very similar so it is difficult to distinguish. Whether the diesel engine in the operation when the noise is what reason, we all need to timely handle this time, fiber laser cutting machine professionals said the only way to better to use the machine.
