Three phase winding 311

MECHANIC FEATURES

Frame

All industrial standard is IP22,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.

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 1and 3%s fluctuation of the speed of engine. Voltage is adjusted via potentiometer of AVR

ELECTRIC FEATURES

INSULATION

Insulation Class H

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.

Radio interference

Brushless apparatus and quality AVR ensure little radio interference in transmission. RFI noise filter is also available.
