Hot sell Quality Reliable High voltage Solid Soft Starter WGQH

Product Description

Introduction

WGQH High Voltage Solid Soft Starter is a new type high voltage motor soft stator which is suitable to high and medium voltage squirrel-cage AC motor under *0 KV. It is now 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, conveyer, elevator, centrifuge, rolling mill.

Performance Characteristics

1. 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 equipments with motor.
2. The main circuit is equipped with component-based structure, modularized installation method, which can reach the target of multiple over-voltage absorption and protection. This device can multiply limiting the clamp of transient dv/dt, lighting impulse voltage, operation wave over-voltage and that of transient transition process. It has unique measures and methods to reach pressure balancing of di/dt, valve recanalizing and turn-off.
3. Different current intensities are isolated perfectly. The system adopts high anti-interferential digital contactor, matched with fiber/CT isolation transforming technology, which helps to avoid interference of each current, making the high voltage performance is as reliable and safe as low voltage devices.
4. 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, and then it will take corresponding measures to protect the equipment from expending.
5. It has a high effect of over *6% (top to *7%), which is far effective than other soft starters.
6. It cans perfectly protect the stator and motor from faults like short circuit, over-current, current limiting, over-voltage, under-voltage, overload, open-phase, three phases current unbalance, overheat, communication fault.
7. Unique heat dissipation design cans effectively cool the thyristor.
8. The device has several selectable starts like standard start, constant current start, double voltage harmonic start, start with sudden jump, etc.
9. It is of small volume, low power dissipation, high sensitivity, and non-contact and so on, and is easy to install.
