Cabinet layout
The DC/DC converter cubicle includes a converter module, a BDCL filter module and a
BCU control unit. Each converter is equipped with dedicated DC fuses; a DC
switch/disconnector is optional (F286) but commonly used. A converter unit with a
DC switch/disconnector also has a precharge circuit including a charging switch on the
door.
The figures show the components of the converter unit cubicle with the door closed, and
with the door open and shrouds removed. In this figure, the DC/DC converter unit cubicle
has the DC switch/disconnector and charging circuit.
