Description
Main FUNCTION:
smooth start, without shook to equipment, extend the using
life,save equipment maintain cost
reduce the temperature increasing of motor, largely
extend the long of motor, also save the electricity power
RANGE OF APPLICATION:
This product is suitable to heavy load soft starting of wound rotor
asynchronous motor,
especially in industrial or mines with unstable or lower
voltage
SUCH AS : mine, cement, metallurgy, chemical industry,light
industry, city planning, petroleum, electric power ,etc
PERFORMANCE CHARACTERISTICS:
it start smoothly, no mechanic pulse on the machine and a
longer working life to both equipment and motor
reduce motor starting temperature rise, effectively lengthen the
motor's life
the cabinet and water tank adopt a full-closed structure, which can
avoid evaporating of the electrolyte,lengthen the equipment working
life and reduce the mantaining frequency.
it can start under a lower voltage, for example, start in 5.5KV
when rated voltage 6KV
the equipment is especially suitable to be long time used in
climate of less than **0mm raning yearly
with a cycle pump, a unique automatic cycle colling system designed
for this product, can release the leat in the tank in very short
time
it can be started continuously for ***0 times
it adpts worm gear and worm lifter as the transformation tool,
which is stable,reliable and noiseless
low starting current: the starting current is<=
1.3Ie(A)
the equipment has reliable cabinet struction, which is wholly
automatically operated and convenient to be installed and
maintained.
OPERATING PRINCIPLE:
For wound rotor asynchronous motor, when the grid voltage and
frequency are invariant,
the connection of the starting resistor to the rotor loop
will reduce the starting current and get a larger starting
torque.
putting special compound electrolyte into the rotor loop of
the controlled winding motor as the liquid resistance, when
the stator receive the signal of the motor starting, it will
change the location of the electrolyte automatically, so as to
reduce the resistance value gradually. when the resistance reached
the minimum level, the sensor closed and motor rotor star connected
directly, then the equipment start smoothly with a low current,
large torque.
