1100kw Stamford Brushless ac Synchronous 1500kva Generator

1100kw Stamford brushless ac synchronous 1500kva generator

1. Application

    The XWS brushless stamford generator are to be used in town, the countryside, work sites, mountain and pasture lands as a electric power source for lighting purpose, it can also be used as a reserved power source for emergent case. The generators are of drip-proof with rotary field type and with the adoption of harmonic excitation system, that allow your easy operation and simple maintenance. The generators are of three-phase four-wire type, making use of atar connection with neutral point. The rated line voltage is 400V, phase voltage 230V, frequency 50Hz, power factor 0.8(lag). It can provide 60Hz and the other voltage's generator according to necessary. 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 revolution slip of slip of prime mover is 3% and load varies in the range of 0-100%, cosΦ1.0-0.8. They give food constant voltage. After sudden change (increase or decrease) of load, the generator will soon return to their normal working state, without any starting devices the generator can directly start an unloaded squirrel cage induction motor.

    All alternator windings are in excellent electric strength manufactured by vacuum impregnation. The stator windings are also manufactured in black resign process for the alternators suitable for operation in moisture, oil vapour, salt contamination environment.

Under the following environment conditions, the generator could run normally and continuously:

1. Altitude: Not exceed 1000m.

2. Cooling air temperature: 258~313K (15 ~40 ).

3. Relative air humidity: Not exceed 90%.

2. Features

1).It can be coupled with any permanent magnetic generators,providing invariable excitation on all occasions.

2).It meets the JB/T3320.1-2000,GB/T1029-2005,IEC60034 standard

3).Single or double bearings are available,options for all kinds of adaptors and disc plates.

4).12-end reconnecttable winding terminals to get different voltages.

5).Easy to operate for lead-end rotated diodes and adaptor connected bolts.

6).IP23 protection class,optional severe environment protection.

3. Parts Features

Shaft & Keys

All alternator rotors are dynamically balance to better than Bs6861 P.1,G2.5 for minimum vibration in operation .Two bearing generators are balanced with a half-key. electric dynamo is used in diesel generator.

Terminal and terminal box

The 3Phase alternators had 12 ends brought out to the terminal box .The terminals are put on the non drive end. The box is equipped with removable panels.

Voltage regulation

Voltage regulation refers to the change of voltage from no-load to full-load with power factor ranging from 0.8 to 1 and 3%s fluctuation of the speed of engines .Voltage is adjusted using a trimmer on the AVR .
