Arrangement and method for connecting and/or disconnecting a plurality of dc sub-networks

An arrangement for selectively connecting and disconnecting a plurality of DC networks to one another, the arrangement comprising:

• a main bus for connecting a plurality of DC lines with each other;
• a first DC line for connection to a first DC network having DC operating equipment, and a first main switch connecting said first DC line to said main bus;
• a second DC line for connection to a second DC network having DC operating equipment, and a second main switch connecting said second DC line to said main bus;
• a transfer bus electrically connected to said main bus, said transfer bus including:
• a transfer bus disconnector for disconnecting said main bus from said transfer bus;
• a transfer switch;
• a current limiting device having a resistor and a parallel resistor bypass switch for bypassing said resistor;
• a first transfer disconnector connected between said first DC line and said transfer bus;
• and
• a second transfer disconnector connected between said second DC line and said transfer bus.
