This middle voltage (high voltage) adjustable frequency drives is of AC-DC-AC voltage type with main loop of multi-level topology circuit. The control mode adopts SPWM (Sinusoidal Pulse Width Modulation) technology. The input uses isolated transformer of multiple technology, while the output is fulfilled by the solution of phase-shifting tandem multi-unit and high-voltage to high-voltage direct conversion.
The 6kv, 6.6 kv medium voltage (mv) frequency inverter, middle voltage adjustable speed drive consists of three main parts: transformer cabinet, power unit cabinet, and control cabinet.
The layout of these 3 cabinets: on the left is transformer cabinet, power unit cabinet is in the middle , while on the right part is control cabinet.
Regarding specialized design for cooling, in order to improve the stability of the control circuit and to make the debugging more convenient, the control cabinet door is put on the right of the machine. Our 6kv, 6.6 kv inverter adopts cabinet structure with forced air cooling. The big capacity machine adopts the cooling mode of water-cooled, air-closed circulation. The wiring terminal of input and output of the complete machine is placed on the lower left back. It is easy for connection
