Description
WGQH high voltage motor soft
starter
GENRAL INTRODUCTION:
WGQH high voltage solid soft starter is suitable for high/medium
voltage squirrel-cage AC motor under*0KV.
IT adopts DSP controlling technique,power and electron technique,
and multiple SCR series/parallel to motor, to protect the motor
completely.
this technique was designed by our own technical deparment, and had
get patent .
comparing with other or traditional starting methos,this device has
unique intelligent controlling way, which can set the starting
parameters as torque,current, time of start and stop as well as
connecting to computer /PLC to reach a net work control
USING AREA:
It is widely used in industry like mechanical manufacture, cement,
metallurgy ,mining, oil production, chemical industry, water
treatment,petrochemical industry, and on loads of pump, blower,
pumping unit, air compressor, ball mill, crane, compressor,
crusher, converyer, elevator, centrifuge, rolling mail, and so
on
PERFORMANCE CHRACTERSTICS:
the device combines series¶llel thyristor, professional
insulating material imported with original packing and modern
power& electric control technology, which is applicable to
large and medium high voltage soft starting equipment with
motors
the main circuit is equippment with component-based
structure,modularized installation method, can reach the target of
multiiple onver-voltage absorption and protection.
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.
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 .
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 , then it will take corresponding
measures to protect the equipment from expending.
it has a ligh effect of over *6%(top to **7), which is far
effective than other soft starter
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,
unique heat dissiipation design can effectively cool the thyristor
and machine
it is of small volume, low power dissipation, high sensitivity, and
non-contact and so on, also easy to install
