側(cè)刀閘、起勵(lì)電源開關(guān)是否均合上。然后再檢查是否有起勵(lì)電源，PT保險(xiǎn)是否熔斷，PT回路的接線是否松動(dòng)。

Whether the side knife switch and excitation power switch are all closed. Then check whether there is a build-up excitation power supply, whether the PT fuse is blown, and whether the wiring of the PT circuit is loose.

如果這些都正常，就需要另?yè)Q一個(gè)通道起勵(lì)。如果能夠正常起勵(lì)了那么就說明是調(diào)節(jié)器通道內(nèi)的原因;如果沼氣發(fā)電機(jī)組還是無法正常起勵(lì)，則應(yīng)當(dāng)檢查起勵(lì)回路、脈沖公共回路、可控硅整流器、轉(zhuǎn)子回路是否有接地或者短路等。

If all of these are normal, another channel is needed to make excitation. If the excitation can be started normally, it indicates that it is the reason in the channel of the regulator; if the biogas generator set is still unable to start excitation normally, check whether there is grounding or short circuit in the excitation circuit, pulse common circuit, silicon controlled rectifier and rotor circuit.

如果調(diào)節(jié)器沒有發(fā)出“起勵(lì)失敗”的信號(hào)，但沼氣發(fā)電機(jī)組仍然無法自動(dòng)起勵(lì)，那么可以在勵(lì)磁盤附近起勵(lì)或者遠(yuǎn)方人工起勵(lì)如果遠(yuǎn)近方都無法人工起勵(lì)，應(yīng)當(dāng)檢查發(fā)電機(jī)組頻率是否沒有達(dá)到45HZ以上。

If the regulator doesn't send out the signal of "excitation failure", but the biogas generator set still can't start excitation automatically, then the excitation can be started near the excitation disk or the remote manual excitation can be started. If the manual excitation cannot be started in the far and near places, it should be checked whether the frequency of the generator set does not reach more than 45Hz.

如果沼氣發(fā)電機(jī)組勵(lì)磁裝置已有勵(lì)磁電流輸入發(fā)電機(jī)勵(lì)磁繞組，但機(jī)組仍然無法建壓成功，則應(yīng)當(dāng)考慮是否存在沼氣發(fā)電機(jī)組起勵(lì)電流不夠的問題，可適當(dāng)調(diào)節(jié)起勵(lì)限流電阻，加大起勵(lì)電流進(jìn)行試驗(yàn)及檢查。

If the excitation current of the excitation device of the biogas generator has been input into the excitation winding of the generator, but the voltage build-up of the unit is still not successful, it should be considered whether the starting excitation current of the biogas generator is not enough. The starting excitation current limiting resistance can be appropriately adjusted and the starting excitation current can be increased for test and inspection.

一般來說，很多機(jī)器或者設(shè)備在平時(shí)運(yùn)行的時(shí)候，都會(huì)產(chǎn)生一些聲音，這些大部分是機(jī)器零件間的碰撞所產(chǎn)生的聲音，但是對(duì)于柴油發(fā)電機(jī)組這個(gè)設(shè)備來說，在它工作的時(shí)候，有的時(shí)候會(huì)出現(xiàn)噪音，是什么樣的原因?qū)е逻@個(gè)現(xiàn)象出現(xiàn)的呢。首先，噪音是由于空氣氣體與物體相互作用而產(chǎn)生的，造成大氣輻射的空氣動(dòng)力噪音。空氣動(dòng)力噪音一般包括進(jìn)氣噪音，排氣噪音以及冷卻風(fēng)扇噪音。

Generally speaking, many machines or equipment will produce some sounds when they are running, most of which are generated by the collision between machine parts. But for the diesel generator set, when it is working, sometimes there will be noise. What is the reason for this phenomenon. First of all, noise is due to the interaction between air and objects, resulting in the aerodynamic noise of atmospheric radiation. Aerodynamic noise generally includes intake noise, exhaust noise and cooling fan noise.

還有一種情況就是由發(fā)電機(jī)轉(zhuǎn)子在電磁場(chǎng)高速旋轉(zhuǎn)產(chǎn)生的電磁噪音，另外還要兩種就是燃燒噪音和機(jī)械噪音，這兩種很相似所以很難分辨。無論沼氣發(fā)電機(jī)組在運(yùn)行的時(shí)候出現(xiàn)噪音的原因是什么，這個(gè)時(shí)候我們都需要及時(shí)的處理好，人士表示只有這樣才能更好的去使用這個(gè)機(jī)器哦。

Another case is the electromagnetic noise generated by the high-speed rotation of the generator rotor in the electromagnetic field. The other two are combustion noise and mechanical noise, which are very similar, so it is difficult to distinguish them. No matter what is the cause of the noise when the biogas generator set is running, we need to deal with it in time. Professionals say that only in this way can we better use the machine.
