Technical Data

MECHANICAL FEATURES

Voltage regulation

Voltage regulation refers to the change of voltage from no-load to full-load with power factor ranging from 0.5 to 1 and 2.8%s fluctuation of the speed of engine. Voltage is adjusted via potentiometer of AVR, model: SX460, SX440

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.

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. This and the 2/3 pitch help to check the wave distortion and output voltage.

Phone interference and Radio interference

THF (defined by 40thpart of BS4999) <2%.TIF<50

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

Manufacturing Standard

GB755,BS 5000,VDE 0530, NEMA MG1-22,IEC34
