Alternator

 

All

 

of

 

the

 

alternators

 

chosen

 

by

 

HYUNDAI

 

Power

 

are

 

single

 

bearing

 

self

‐

excitation

 

brushless

 

alternators

 

with

 

the

 

attributes

 

of

 

international

 

top

 

brand.

 

By

 

citing

 

Stamford

 

alternator

 

as

 

an

 

example,

 

we

 

can

 

illustrate

 

the

 

features

 

of

 

our

 

alternators

 

as

 

follows:

 

◆

Four

 

polar

 

brushless

 

self

‐

excitation,

 

single

 

bearing,

 

insulation

 

class

 

is

 

H

 

and

 

protection

 

level

 

is

 

IP22.

 

◆

Stators

 

are

 

wound

 

to

 

2/3

 

pitch,

 

which

 

can

 

effectively

 

eliminates

 

triple

 

and

 

curbs

 

waveform

 

deformation

 

of

 

output

 

voltage.

 

When

 

in

 

parallel

 

with

 

the

 

mains

 

or

 

other

 

generator

 

sets,

 

this

 

type

 

of

 

winding

 

can

 

effectively

 

avoid

 

excessive

 

neutral

 

currents

 

and

 

reduces

 

inductive

 

heat.

 

◆

Before

 

being

 

assembled,

 

rotors

 

need

 

to

 

pass

 

dynamic

 

balance

 

testing.

 

The

 

improved

 

damper

 

reduces

 

voltage

 

deviation

 

and

 

heat

 

under

 

unstable

 

load.

 

◆

The

 

exciter

 

rotor

 

output

 

is

 

fed

 

to

 

the

 

main

 

rotor

 

through

 

a

 

three

 

phase

 

full

 

wave

 

bridge

 

rectifier,

 

the

 

rectifier

 

is

 

protected

 

by

 

a

 

surge

 

suppressor

 

against

 

surges

 

caused

 

by

 

short

 

circuit

 

or

 

out

‐

of

‐

phase

 

paralleling.

 

◆

Automatic

 

voltage

 

regulator

 

has

 

the

 

feature

 

of

 

automatic

 

load

 

curtailment

 

which

 

is

 

used

 

to

 

protect

 

the

 

engine,

 

and

 

make

 

it

 

possible

 

to

 

add

 

full

 

load

 

to

 

the

 

alternator

 

at

 

one

 

time.

 

Steady

 

state

 

voltage

 

adjusting

 

rate

 

can

 

reach

 

±1%

 

(under

 

certain

 

requirements,

 

steady

 

state

 

voltage

 

adjusting

 

rate

 

can

 

meet

 

±0.5%).

   

If

 

PMG

 

system

 

is

 

chosen,

 

the

 

motor

 

will

 

have

 

high

 

starting

 

capacity

 

and

 

the

 

ability

 

of

 

interference

 

rejection

 

for

 

the

 

deformed

 

voltage

 

waveform

 

fed

 

by

 

the

 

main

 

stator

 

generated

 

by

 

non

‐

linear

 

load(such

 

as

 

silicon

 

control

motor,

 

UPS

 

etc).

Cooling

 

System

 

The

 

engine

 

cooling

 

system

 

is

 

water

 

cooled.

 

The

 

water

 

cooled

 

system

 

is

 

comprised

 

of

 

a

 

radiator

 

a

 

pusher

 

fan

 

and

 

thermostat.

 

The

 

alternator

 

has

 

its

 

own

 

internal

 

fan

 

to

 

cool

 

the

 

alternator

 

components.

Fuel

 

Tank

 

and

 

Base

 

Frame

 

The

 

engine

 

and

 

alternator

 

are

 

coupled

 

together

 

and

 

mounted

 

on

 

a

 

heavy

 

duty

 

steel

 

base

 

frame.

 

This

 

base

 

frame

 

includes

 

a

 

fuel

 

tank

 

with

 

capacity

 

of

 

approximately

 

8

 

hours

 

operation

 

under

piping

 

and

 

to

 

the

 

overflow

 

piping

 

containing

 

fuel

 

from

 

the

 

injector

 

drain.

 

Big
