Features:
1)Any permanent magnetic generators, providing invariable excitation on all occasions.
2)Easy to be connected with power network or other generators. Standard 2/3 pitch windings check excessive midline current.
3)Balanced rotor with single or two sealed ball bearings
4)Convenient installation and maintenance with easy access to terminals, rotating diodes and coupling bolts
5)Wide range of Flange adaptor and single bearing coupling discMeet leading standards
MECHANIC FEATURES
Frame
All industrial standard is IP21,also IP23 is an option, but rates power will decrease 5%
Marine standard alternator is IP23,Air filter is an option, but rated power of the alternator will decrease 5% while it is installed.
Axis and Key
All of alternator rotors should pass balance test, whose vibrations are lower than the minimum of BS6861 P.1,G 2.5 two bearing alternator has a half-key testing balance
Terminal and terminal box
The three-field alternator had 12 leads brought out to the terminals in 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 engine. Voltage is adjusted via potentiometer of AVR.
ELECTRIC FEATURES
INSULATION
Insulation Class H
All regulatory components are made up with special materials and are immersed in lacquer by peculiar tech. Vanish and colophony materials are develop to strengthen the processing and machinery intensity of windings and revolving parts for protecting the alternator work under corrosive environment.
Winding and electric features:
2/3 pith winding design can effectively eliminate the third harmonic wave(3th.9th,15th) of the voltage ,which is the best design of UPS for nonlinear load .Connected with the network in parallel, the structure can restrain excessive currents in the midline
A continuous damp windings abates surges. The poles and gears of the windings are carefully chosen, this and the 2/3 pitch help to check the wave distortion and output voltage.
