Model:Full protection
high voltage motor soft
starter
1)
direct starting problem
motor will create big current shake if start directly
( **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 and stop is
neccessory
2)
intelligent WYT main function
1:smooth start, without shook to equipment, extend
the using life,save equipment maintain cost
2:reduce the temperature increasing of
motor, largely extend the long of motor,
3:Full protect motor
3)range of
application:
suitable to heavy load soft starting of wound rotor
asynchronous motor,
especially in industrial or mines with unstable or
lower voltage
Successfully widely used by 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.
4)unique
feature:
1: low starting current: the starting current
is<= 1.3Ie(A)
2: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.
3:it can start under a lower voltage, for example,
start in 5.5KV when rated voltage 6KV
4:the equipment is also suitable to be long time
used in climate of less than **0mm raning yearly
5: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
6: can started continuously for ***0 times
7: adpts worm gear and worm lifter as the
transformation tool, which is stable,reliable and
noiseless
8: the equipment has reliable cabinet
struction, which is wholly automatically operated and
convenient to be installed and maintained.
5)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.
