Starlight generator

As we all know, the service life of diesel generator set is closely related to correct operation and reasonable use. When the unit breaks down, it needs to be repaired in time, but some users think that some minor faults do not affect the use of the unit, so they ignore them, and they will not repair until the unit "strikes", which is extremely incorrect. Today, I'll talk about the harm of diesel generator set's small failure and untimely maintenance. 1.If the maintenance of small faults of diesel generators is not timely, there will be short-circuit between turns of stator winding, which will generate ring current under the action of short-circuit voltage, which may cause turn to turn short circuit to develop into single-phase ground short circuit and phase to phase short circuit. When the multi-phase phase to phase short circuit occurs in the stator winding, it is the most harmful to the unit, and the short circuit current will cause the unit to burn down. ...

The voltage regulator (AVR) is a kind of sealed electronic device. By controlling the low-power exciter magnetic field and adjusting the rectifier output power of the exciter armature, it can control the magnetic field current of the host machine and stabilize the output voltage of the brushless generator. It has low-frequency and no input signal protection devices. With parallel compensation function, it can meet the needs of customers' capacity expansion. Therefore, it is very important to maintain the voltage regulator (AVR). So, what are main causes AVR damage? 1.AVR circuit consists of three parts: rectifier main circuit, voltage detection circuit and comparison control circuit. Excluding the possibility of damage caused by the quality of the original electrical components, in the whole AVR circuit, the working frequency of the main circuit and comparison control circuit changes the most; the rectifier bridge of the main circuit and the transistor of the comparison cir...

Diesel generator set is a power generation equipment, it uses diesel oil, driven by a diesel engine to generate electricity. The whole set of diesel generator is generally composed of diesel engine, generator, control cabinet, fuel tank, storage battery for starting and control, protection device, emergency cabinet and other components. The alarm function of the diesel generator set will automatically start and sound when the diesel generator has the following conditions: 1.Over speed. 2.High water temperature in water tank. 3.Low oil pressure. 4.Over current display on the control panel. 5.Over voltage. 6.When other abnormal phenomena occur, the alarm function of diesel generator set starts or the self-protection function of diesel generator plays a role.   What is the reason of faults for low voltage shutdown? 1.Mechanical speed regulation of diesel engine Diesel engine speed regulation includes electronic speed regulation and mechanical speed regula...

The high water temperature of diesel generator set is mainly caused by the following reasons: 1. The diesel generator unit uses hard water for a long time. When the generator unit is used, the water tank will generate temperature, so a large amount of scale will be formed in the water tank and water channels, resulting in poor heat dissipation. 2. There are too many impurities in the water channel between the generator body and the cylinder head, which makes the water circulation not smooth and causes poor heat dissipation. 3. The generator set burns engine oil seriously, resulting in excessive carbon deposition and poor heat dissipation. 4. Improper operation and use of diesel generator. When starting the diesel generator, it is necessary to preheat it for a period of time with the medium and small throttle. Do not suddenly increase the throttle and load, otherwise the diesel generator will work rough and the temperature will increase sharply. O...
