high voltage motor soft starter / motor drive control device

タイトルまたは説明

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
