Transformer Panel
The transformer panel houses a Three-phase transformer with multiple windings on the secondary side. The number of
secondary winding on the transformer differs according to the output voltage class as shown below.
2 kV class: Six 3-phase windings
3 kV class: Six 3-phase windings
4 kV class: Six 3-phase windings
6 kV class: Nine 3-phase windings
11 kV class: Fifteen 3-phase windings
Each of the windings is connected to a three-phase input terminal of the Power Cell.
Multiple cooling fans for the transformer panel are mounted in the upper section of the drive panel. Cooled air taken in
through the filters on the front of the transformer panel passes the transformer panel and is expelled into the upper section
of the drive panel.
Note:
Some models in which the cooled air from the fronts of both the transformer panel and Power Cell panel through the transformer
panel and is expelled into the upper section of the drive panel.
u
Power Cell Panel
The output side of the Power Cell Panel houses multiple Power Cells. The number of Power Cells will differ according to
the voltage class:
2 kV class: Total of 6 Power Cells (Two for each phase)
3 kV class: Total of 6 Power Cells (Two for each phase)
4 kV class: Total of 6 Power Cells (Two for each phase)
6 kV class: Total of 9 Power Cells (Three for each phase)
11 kV class: Total of 15 Power Cells (Five for each phase)
Multiple cooling fans for the Power Cell panel are mounted in the upper section of the drive panel. Cooled air taken in
through the filters on the front of the Power Cell panel passes the Power Cell fins in the cooling section, flows into the air
duct at the rear of the drive, and is expelled into the upper section of the drive panel.
Each Power Cell consists of a power section and a control board. Each control board is connected to the controller in the
control panel with a fiber optic cable. The control board controls PWM output of the Power Cell according to the
references sent from the controller through the fiber optic cable. The control board has protection functions against
overvoltage, undervoltage, IGBT overheat and other problems, and sends feedback to the controller through the fiber
optic cable.
u
Control Panel
The control panel houses the following devices.
All external cables except the input and output cables of the main circuit are connected to the control terminals.
• Controller and control power supply to control the drive
• MCCB (Molded Case Circuit Breaker)
• Contact I/O relay
• Peripheral circuits such as an isolation amplifier for analog I/O
• Control terminals
Note:
A Single-phase, 200/220-Vac power supply is required as the power source for the cooling fan and control circuit.
