Starlight generator

1.Use the starting battery (12V) of the diesel engine to power on the excitation wire (2 carbon brush wires) for a few seconds. It is better to magnetize it during operation. As soon as the battery contacts the excitation wire, the generator magnetizes and circulates to increase the magnetic field. 2.It should be noted that the time of grounding should not be too long, and that the speed of the diesel engine is slightly higher, it is better to carry a load, and connect an electric lamp, so as to know whether the magnetization is successful at any time. The reasons of no electricity in Volvo generators : 1.After shutdown, the remanence is often lost because the material used for the exciter pole is close to soft steel, and the remanence is small. When there is no current in the excitation winding after shutdown, the magnetic field disappears. 2.The pole of the generator loses magnetism. 3.The excitation circuit element is damaged or the circuit has open circuit,...

Generator loss of excitation fault means that the excitation current provided by the excitation system suddenly disappears completely or partially. After the synchronous generator is out of magnetic, it will be transferred to the asynchronous running state, and the reactive power will be absorbed from the original reactive power conversion. The causes of generator loss of magnetism fault are: generator rotor winding fault, excitation system fault, automatic demagnetization switch trip and circuit fault. The effect of generator loss of excitation on the system: 1. Low-excitation and magnetic-loss generators absorb reactive power from the system, causing the voltage of the power system to decrease. If the reactive power reserve in the power system is insufficient, the voltage in some adjacent points in the power system will be lower than the allowable value, which destroys the stable operation between the load and each power supply, and even collapses the power system voltage. ...

In generally, it is no problem to let diesel generator set idle no more than 10 minutes. If idling for a long time, will cause diesel engine damage. In this article, we mainly talk about idling of Perkins generator. 1.What is diesel generator set idling? Idle state, that means diesel generator set work without any load. That is to say, under this working condition, the generating set does not need to bear load, as long as it keeps the low speed required for smooth operation.  2.   Why can not let Perkins diesel generator set idle for a long time? A.   If Perkins diesel generator set idles for a long time, it will also reduce the quality of fuel injection atomization, accelerate early wear of cylinder wall. Because the quality of atomization is directly related to the injection pressure, injector aperture and camshaft speed of Perkins diesel generator set. Because the injector aperture remains unchanged, the quality of fuel atomization depends on the ...

The noise reduction of diesel generator sets  needs to deal with the causes of the above noise respectively. The main methods are as follows . 1.  Air intake and exhaust noise reduction: the intake and exhaust air channels in the engine room are used as soundproof walls, and the silencers are set up in the inlet and exhaust air channels. There is a distance buffer in the channel, which can reduce the intensity of the sound source radiation from the engine room. 2.  Control of mechanical noise: the top and surrounding walls of the machine room are covered with high absorption and sound insulation materials, which are mainly used to eliminate indoor reverberation and to reduce the sound energy density and reflection intensity in the machine room. In order to prevent the noise from radiating through the gate, fire-proof iron door is set. 3.  Control smoke noise: the smoke exhaust system installed on the basis of the original primary silencer special two...
