In the large-grade rolling shop of Azovstal PJSC, commissioning and commissioning were completed and the previously delivered transformers of the main electric drive of mill 800 – КТЕ5-АС-10к/930-В04340-С23-УХЛ4 for supplying the anchor circuits of the engine were commissioned П2-23/106-7,1УХЛ4 and КТЕ5-ВС-500/440-ЕР1100-С01-УХЛ4 for supplying the field winding.
- rated power, kW 7100
- rated rotation speed, rpm 80/125
- rated current of the anchor, In, А 8050
- rated voltage of the anchor, V 930
- overload capacity, In:
• maximum working 2,5
• shutdown 2,75
The thyristor converter for powering the anchor circuits is made according to a 12-pulse circuit and consists of 2 reverse thyristor bridges.
In the converter for supplying the anchor circuits, devices for remote on-line monitoring of the converter’s operation by the manufacturer via the Internet are installed – the quality of regulation, the reading of emergency “traces”, etc.
