For 3 Phase 4 Pole alternators

Features:

1. Optional permanent magnetic alternator , provide invariable excitation in any situation.

2. Easy to be connected with power network or other alternators. Standard 2/3pitch windings avoid excessive neutral current.

3. Dynamically balanced rotors, with single or two sealed ball bearings.

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.

6.Built to conform to all leading industrial standards.

Electrical Character:

Excitation system:The main stator supplies power to exciter stator via Automatic Voltage Regulator (AVR) .The output of exciter rotor is fed to the main rotor through a three phase full wave rectifier. There are varistors at the both ends of the rectifier for restraining surge voltage and avoiding the impact caused by short circuit or parallel synchronization loss.

Exciter stator is equipped with permanent magnetic steel in order to start up the alternator smoothly in any occasion.

Insulation/Immersion

Insulation class H

All wound components are made up with specialized material and immersed in varnish by especially technology. Resin matrix material is developed to strengthen the process and machinery intensity of windings and revolving parts for the alternator working under harsh environment.

Windings and electric features

Standard 2/3 pitch windings design can eliminate the triple frequency harmonics on the voltage waveform which is the optimum design for trouble-free supply of non-linear loads.

Connected with the network in parallel, the structure can restrain excessive currents in the midline. A fully damp winding reduces oscillations during paralleling. This winding, with 2/3pitch and carefully selected pole and tooth designs, ensures very low waveform distortion.

Wiring terminal and terminal box:

Standard alternator is 3 phase re-connectable to 12 ends brought out to the terminals, which are mounted on a cover at the non-drive end of the alternator .A sheet steel terminal box contains the AVR and provides ample space for customer’s wiring and gland arrangements. It has removable panel easy access.
