沼气发电机组起励建压失败与什么有关?

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。
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;如果沼气发电机组还是无法正常起励,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 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.
如果调节器没有发出“起励失败”的信号,但沼气发电机组仍然无法自动起励,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 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.
瓦斯发电机组
如果沼气发电机组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沼气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 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。
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.
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。无论沼气发电机组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,人士表示只有这样才能更好的去使用这个机器哦。
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.
