What are the main causes of AVR damage?

I. Main cause analysis of AVR damage:
The AVR circuit consists of three parts of the rectifier main circuit, the voltage detection circuit, and the comparison control circuit; the possibility of damage to the original electrical component itself, in the entire AVR circuit, main circuit and comparison control circuit Working frequency change zui; wherein the rectifier bridge and the transistor fluctuation in the comparison circuit are more frequent, and the damage ratio accounts for more than 90% of the entire AVR damage rate;generatorThe AVR belongs to the non-demortical accessories. If it is damaged, it will be replaced. Therefore, we mainly analyze the causes of AVR damage on the generator, avoiding the damage of AVR as much as possible, as long as you use appropriate, you can improve the use of AVR life.
(1)generatorThe more stable the voltage, the smaller the frequency of change in the AVR; the crystals in the comparison circuit
The smaller the switching operation of the tube, the smaller the chance of the AVR damage;
(2) The output load is relatively stable, the smaller the variation frequency in the AVR, and the crystals in the comparison circuit.
The smaller the switching operation of the tube, the smaller the chance of the AVR damage;
(3) The more stabilizing the speed of the diesel engine, the smaller the change in the oscillation impact of the AVR;
(4) Regular \"Avanthus \" and overload, the three-phase load is too large to cause AVR damage
main reason;
(5) Select the generator set with E, F, C fuel system, due to the frequency change, AVR
Use will be more reliable.
