1) Main function

High voltage motor will creat big shake if start directly, heavily influence the motor service life and loaded equipment , some times motor burnt .

WGQH motor soft starter will solve this problem, also with power save and full protection function.

2)USING AREA:

Suitable for AC squirral cage motor

Rated voltage under 10KV

Rated power : 500KW ~11000KW

 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)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 96%(top to  97%)

3>:the device combines series&parallel thyristor, professional insulating material imported with original packing and modern power& electric control technology 

 3)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

Worldwide Electric Stock Co., LTD (hereinafter referred to as Worldwide Electric) was a scientific & technical joint-stock enterprise integrating scientific research and development, production and operation. Its business scope cover: electric energy saving & control for related high/low voltage components, device, system integrated whole sets, system software / hardware, systems engineering technique and R&D/ design / produce/ vendition/ consultation service/ imports and exports of products.
