The new reference of ELMARK PLUS at the Novaky mine.

In March 2016 we put into operation, performed all the tests and gave the Frequency control voltage drive mining fan 1000 kVA to Hornonitrianske bane, Prievidza.

The mining ventilation fan is located in the underground mine ventilation pit "F" in the Novaky mine. It is used to maintain the constant depression air (vacuum) in underground mines. It is powered by the electric voltage 6000 V, 1000 kVA.

The customer required continuous regulation of the fan speed while maintaining the original electric motor and cabling. We have designed a technical solution by using a voltage (6000 V) frequency drive type Allen Bradley PowerFlex 6000, manufacturer Rockwell Automation. After approval of this solution we implemented it as a leading general contractor, i.e. design, delivery, installation, inspection, official testing, commissioning, and individual and complex tests. We've met all customer requirements - voltage electric stayed original (aged about 40 years), and the voltage cabling remained original, too.

The integrated frequency drive PowerFlex 6000 is almost the ideal sinusoidal output voltage and current, it was not necessary to use the sinusoidal output filter. The drive also has a minimal impact on the power grid - the orientation of the input voltage is 36 pulses.

The drive works well for the maximum customer satisfaction. We are really proud of our application!
