沼气发电机组起励失败的缘故为什么会产生噪音

侧刀闸、起励电源开关是否均合上。然后再检查是否有起励电源,PT保险是否熔断,PT回路的接线是否松动。

  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.

  如果这些都正常,就需要另换一个通道起励。如果能够正常起励了那么就说明是调节器通道内的原因;如果还是无法正常起励,则应当检查起励回路、脉冲公共回路、可控硅整流器、转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.

  如果调节器没有发出“起励失败”的信号,但发电机仍然无法自动起励,那么可以在励磁盘附近起励或者远方人工起励如果远近方都无法人工起励,应当检查发电机组频率是否没有达到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.

  如果励磁装置已有励磁电流输入发电机励磁绕组,但机组仍然无法建压成功,则应当考虑是否存在发电机组起励电流不够的问题,可适当调节起励限流电阻,加大起励电流进行试验及检查。

  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.

  一般来说,很多机器或者设备在平时运行的时候,都会产生一些声音,这些大部分是机器零件间的碰撞所产生的声音,但是对于柴油发电机组这个设备来说,在它工作的时候,有的时候会出现噪音,是什么样的原因导致这个现象出现的呢。首先,噪音是由于空气气体与物体相互作用而产生的,造成大气辐射的空气动力噪音。空气动力噪音一般包括进气噪音,排气噪音以及冷却风扇噪音。还有一种情况就是由发电机转子在电磁场高速旋转产生的电磁噪音,另外还要两种就是燃烧噪音和机械噪音,这两种很相似所以很难分辨。无论柴油机在运行的时候出现噪音的原因是什么,这个时候我们都需要及时的处理好,光纤激光切割机的专业人士表示只有这样才能更好的去使用这个机器哦。

  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.
