Brushless Generator
Features:
1).Advanced automatic voltage regulator conttrol for trouble-free operation under the most demaning condition
2).Easy paralleling with mains or other generators .Standard 2/3 pitch windings avoid excessive neutral currents. One slot sttor skewing further reduces harmonics.
3).Dynamically balanced rotor,with sealed-for-life ball bearings and single or two-bearing construction.
4).Simple installation and maintenance with easy access to terminals,rotating diodes and coupling bolts.
5).Wide range of Flange adaptor and single bearing coupling disc.
MECHANICAL FEATURES
Enclosure
IP23(NEMA 1) is standard for all industrial and marine generators .
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.
Terminal and terminal box
The 3Phase altenrators 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 .
ELECTRIC FEATURES
Insulation:
The insulation system is class H
.All wound components are impregnated with materials and processes designed specifically to provide protection against the harsh environments encountered in generator applications. Resin based materials are selected and developed to provide the high build required for static windings and the high mechanical strength required for rotating components.
Winding and electric features;
Generator stator is wound to 2/3 pitch. This eliminates triplen (3rd, 9th,15th…) harmonics on the voltage waveform and is found to be the optimum design for trouble-free supply of non-linear loads. The 2/3 pitch design avoids excessive neutral currents sometimes seen with higher winding pitches, when in parallel with mains. A full connected damper winding reduces oscillations during paralleling. This winding, with 2/3 pitch and carefully selected pole and tooth designs, ensures very low waveform distortion.
Telephone interference
THF(as defined by BS4999 Part 40) is better than 2%. TIF(as defined by ASAC50.12) is better than 50.
Radio intterference
The absence of brush-gear and the high quality AVR ensure low levels of interference with radio transmissions.RFI suppression may be supplied if required .
Damper Winding
The alternators incorporate a damper winding in order to ensure good parallel running with mains network and other machines. Inserted into the shoes of the poles are the bars of the damper winding which are connected together at each end of the poles to form a closed cage. This arrangement provides the alternator with excellent damping against the torsinal vibration that occurs during changes in load and when running in parallel.
Accessories & Option
Droop kit for sharing of reactive current during parallel operation
Remote voltage potentiometer
PT100 thermal protection embedded in stator windings
Anti condensation heaters
IP23 protection
