Control for under 10kv squirrel cage AC motor, stepless start without any stroke 

high effective for motor power saving and protection

  

for motors on loads of pump, blower, pumping unit, air compressor, ball mill, crane, compressor, crusher, converyer, elevator, centrifuge, rolling mail, and so on

  

2)GENRAL INTRODUCTION:

 IT adopts DSP controlling technique,power and electron technique, and multiple SCR series/parallel to motor, to protect the motor completely.

  

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

 

 Successfully applied in  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

 

 3)Device Advantage:

 1: it has a ligh effect of over 96%(top to  977), which is far effective than other soft starter

2: 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,

 

3:the device combines series&parallel 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

 

4:the main circuit is equippment with component-based structure,modularized installation method, can reach the target of multiiple onver-voltage absorption and protection.

5: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.

 

5: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 .

 

6: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.
