Model :
WGQH high voltage cage motor soft start / soft
stop
Description: National patent
owned ,digital intelligent control
1) Main function
High voltage motor will creat big shake if start or stop directly,
heavily influence the motor service life and loaded equipment ,
some times motor burnt .
WGQH motor soft start/ stop is high-tech national patented product
.
1) reduce motor start current, high efficient in saving
power
2)much more protection function (as following
introduction)
3)easy install, free maintenance, save maintenance cost
4)highly increase the motor service life
5)accurate setup start torque /start current/start time/ stop time/
etc
6) can connect to computer, PLC

3)Working principle:
1> IT adopts DSP controlling technique,power and electron
technique, and multiple SCR series/parallel to motor, to protect
the motor completely.
2>it
has a high effect of over *6%(top to *7%)
3>:the device combines series¶llel thyristor,
professional insulating material imported with original packing and
modern power& electric control technology
4)Unique Feature:
1> It perfectly protect the stator and motor from faults like
short circuit, over current,current limiting, over-voltage,
under-voltage,over load, open-phase, 3 phase unbalance, over heat,
communication fault,
2>the main circuit is equippment with component-based
structure,modularized installation method, can reach the target of
multiiple onver-voltage absorption and protection.
3>it multiply limiting the clamp of transient dv/dt, lighting
impulse voltage,operation wave over-voltage and that of transient
transition process. it has unique measure and methos to
reach pressure balancing of di/dt, valve recanalizing and
turn-off.
4>different current intensities are isolated perfectly, the
system adopts high anti-interferential digital contactor, matched
with fiber/CT isolation transforming technology, which help to
avoid interference of each current, making the high voltage
performance is as reliable and safe .
5>:the specially designed fault detection return and judging
system can pass the detecting result to the control circuit in time
and start the sound and light alarm
6>unique heat dissiipation design can effectively cool the
thyristor and machine
7>it is of small volume, low power dissipation, high
sensitivity, and non-contact and so on, also easy to
install
