La description
squirrel cage motor will create big current shake when it is start
in full volatege ( **8 times more than rated current), especially
for big capacity motor, it will make big trouble for electic grid
and other loaded equipment,heavily reduce the equipment service
life. so, smooth start and stop is neccessory for motors.
this type starter is designed for 5.5kw***0kw squirrel cage
motor
Â
TYPICAL APPLICATION RANGE:
PUMP: wiht pump control function, reduce pump current water hammer
brought about by the liquid current impaction at starting and
stopping, save the maintenance cost of the system
Â
BALL MILL: with voltage slope starting, reduces the wear and tear
of the gear torque , and work load of maintenance and
lengthens the service lift
Â
FAN: the solid soft starter replaces the traditional starter,
reduces wear and tear and mechanical shock
Â
COMPRESSOR: using current limiting , to realize smooth start and
lower the motor templerature rise
Â
CRUSHER: locked rotor protection and quick protection make it to
avoid motor over-hearting /burning caused by mechanical
faults and block
Â
CONVERYING MACHINERY: soft starting and stop control realize the
smooth and gradual start process, and smooth slowing stop ,thus
avoid damage caused to material and equipment by shocks
Â
Successfully applied in many famous big Project and places, such as
Three Georges project, national engineering designing institute,
mining company, cement mill, stell mill,sugar factory,wood
industry, chemical industry, city planning, and other place with
big power motor and high electric consume place.
Operating principle and performance characteristics
WGQ8 intelligent starter adopts three pairs of parallel thyristor
put in the stator loop of motor,use switch function of thyristor to
control its touching angle with microcontroller, so as to control
voltage of the motor to make it soft start.
when motor start is over and current of motor falls to the oridnary
level, it can control bypass signals to motivate bypass switch, put
the motor parallel to the power grid
Â
Controllable start current: under common load condition, start
current can be controlled <= rated 1.***4A. ,reduce the start
current and motor temperature increasing.
Â
With strong anti-interference ability: adopt high performance
microprocessor digital control,reliable working and strong
anti-interference ability.
Â
Human-machine interface: consist of **8X*4 dot matrix
character LCD, 3 signal indicators, 6 simple keyboards,. show the
data directly and operate easily
Â
 6 kinds of start way: voltage slop start, current-limit slope
start, impulse jump start, slope steady start, steady start and
point start which are applicable to all kind of loads.
Â
two shut down way: SOFT SHUT DOWN and FREE SHUT DOWN. SOFT shut
down characteristics can meet mechanic demands of various
situation, and the time and voltage for soft shut down can be
adjusted
Â
Protection and monitor: it has *7 kinds of protection role: such as
over/ under voltage, over/under current, overheat, overload, short
circuit, open-phase, overheat, communication faults, etc. It will
stock the fault data for user's analyze.
Â
Analog output: ***0mA standard analog current output
Â
other working condition: no efflorescence, no inflammable and
explosive, no aggressive gas ( special requirement please state
when place order)
