Medium Voltage Drive by Automation & Engineering Services

CHH100 Series Medium Voltage Drive:

As a new generation of medium voltage variable frequency speed regulating devices developed and produced by INVT, CHH100 series medium voltage drive adopts a mature power unit tandem technique and therefore have stable and reliable work. The control system is designed with multiprocessing control architecture and use DSP+FPGA.

Features:

CHH100 series medium voltage drive's control accuracy and response speed are improved significantly. The output side uses the phase-shifting multiple pulse width modulation (PWM) technology, so it has an extremely low harmonic content and may be adapted to on-site motors without output filter. CHH100 series medium voltage drive consists of strictly selected parts and is therefore reliable in quality. The human-machine interface is friendly and convenient for operations. Since their launch on the market, CHH100 series medium voltage drive have been extensively used in multiple industries like electric power, metallurgy, mines, cement and petrochemical industry, contributed a lot to the energy saving, consumption reduction and process improvement of enterprises and well accepted by customers.

Technical Features:

1. Sheet metal of hot dip galvanized processing, strong corrosion resistance;
2. Low frequency speed tracking, to effectively ensure the quick restart when power supply drop;
3. Unique synchronous undisturbed switching technology, for the undisturbed switch between power and variable frequency;
4. Large instantaneous non-stop when power off, to effectively avoid downtime of the problems of power grid is not stable;
5. Unique ultra-low frequency oscillation suppression in dead zone compensation technique for better system performance
