STC three phase ac generator

ac generator 1) easy operation and maintenance 2) adopt harmonic excitation system 3) reliable performance

ac generator:

The generators are of dripproof with rotary field type and adopt harmonic excitation system, easy operation and maintenance. They can be coupled with a prime mover directly or through v-belt making right or reverse continuous rotation at the rated speed. When the rotation speed of prime mover changs 3% or so and load varies in the range of 0~100% cos j 0.8~1.0, the generators offer constant voltage, when sudden change (increase or decrease) of load, the generator will soon return to their normal working state, at the same time, without any starting device the generator can directly start an unloaded squirrel cage induction motor.

The generators are three-phase, four-wire type, adopting star connection with neutral point. The rated line voltage is 400V, phase voltage 230V, frequency 50Hz. power factor 0.8(lagging). We can provide 60Hz and the other voltage's generator according to the customer's request. Operating Condiyions: Under the following environment, The generator could be continuous and rated running: Above sea level: Not exceed 1000m Cooling air temperature: 258~313K(-15 degree celsius ~ 40 degree celsius) Relative air damping: not exceed 90%
