Product Details:
Model Number:6GA2492-1A
Key Specifications/Special Features:
The principle of AVR is control the thyristor conduction angle to change the shunt current
of shunt resistor R , in order to control the excitation current.
1FC6/1FJ6 serial generator is constant voltage generator by adjusting the AVR , its high
voltage accuracy , from no load to rated load , the steady state voltage regulation rate
is ±0.5% , when the generator is running in parallel, by adjusting potentiometer S the
steady state voltage regulation rate reached ±0.5% to ±2.5%
1FC6/1FJ6 generator has two kinds of AVR , AVR below 180KW generator without
power module, the other one is with the power module. The difference of these two
kinds of AVR is with the power increased, shunt current also increased , the SCR
in AVR can not meet the primary requirement, so need amplified circuit shunt of
SCR to meet requirements of the generator.
