30 kva generator dynamo 20000 watt generator alternator head

30 kva generator dynamo 20000 watt generator alternator head

Specification:

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 ball bearing 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 disc

6. Meet leading Industry and Marine standards

Electrical Charcter:

Excitation Systerm

AS440,SX460,SA465,SX440,SX421,MX341 or MX321

The main stator provides power for excitation of the exciter field via AVR

Output power of exciter's rotor is input to that of mains through 3-phase full wave rectifier.Two ends of the rectifier are connected with piezoresistance for restraining surge voltage and avoiding the impact caused by short circuit or parallel synchronization loss. Exciter's Stator is equipped with permanent magnetic steel, it can make generator starting smoothly in any occasions.

Voltage regulation(1.0%) and low frequency protection, exterior voltage adjustment of SX440,MX341 and Mx321 suitable for the generator with permanent magnetic generator (PMG)

Frame

All industrial standard generators is IP21(NEMA1), also IP23 is optional, But rated power will decrease 5%,

Marine standard generators is Ip23. Air filter is optional, but rated power will decrease 5% if installed.

Axis and Key

All of the generator rotors pass balance test, The vibrations are lower than the minium of BS6861 P.A,  G2.5 two bearing generator has a half-key testing balance.

Terminal and Terminal  Box

The three-field generator has 12 leads brought out to the terminals in terminal box. The terminals are put on the non drive end. The box is equipped with removable panels

Engine Adaptor and Coupling Disc

SY-A Series single-bearing, engine adaptor: SAE0,1,2,3 and 4; Coupling discs: SAE8,10,11,.5,14 and 18 are available.

SY-A Series double-bearing, engine adaptor: SAE0,1,2,3,4 and 5 are available.

Voltage Regulation

Voltage regulation refers to the change of voltage from non-load to 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

Applications:

It is suitable to match with any brands of the diesel engines in the world,such as USA brand,UK brand, LOVOL, DEUTZ,VOLVO PENTA,DOOSAN,KUBOTA,YANGDONG,LAIDONG,WUDONG,YUCHAI,SHANGCHAI,XICHAI, WEICHAI etc.  It can be used in land, watercraft, railway, hotel and the places need industry power. Our high-quality reliable AC generators are winning great acclaim from the domestic and abroad power generation market.
