Quick Details
Specifications
Model: Economic type WLQ high voltage motor soft starter
1)WLQ Feature:
1) cage motor stepless starter, motor protection device
2)start current <1.5~3.5 rated current(A), save power
3) can start motor in unstable or lower voltage, or power grid capacity is not enough
4)can continuous starting 5~10 times
motor will create big current shake if start directly ( 5-8 times more than rated current), it makes big strike for electic grid and loaded equipment, heavily reduce motor and equipment service life, Sometimes motor burnt .so,stepless smooth start is neccessory
2)PERFORMANCE CHARACTERISTICS:
1>it start smoothly, no mechanic pulse on the machine and a longer working life to both equipment and motor
2>reduce motor starting temperature rise, high effectively lengthen the motor's life
3> PLC control , with sound alarm function for motor protection
4>simple structure, convenient maintenance ,economic cost and low requirement for maintenance staff
3) OPERATING PRINCIPLES:
put special liquid resistor which can perform voltage division and current mimiting into the motor stator loop,
in the starting , liquid resistor's resitance automatically change from large to small within the set time,
when it change to zero, the liquid resistor is automatically cut off and motor get into operation
