Abstract
In a device for disconnecting and/or connecting m phases (u, v, and w) of an alternating voltage providing source (1) from n phases (n1, n2, n3) of a load (3), each of the m phases (u, v, w) of the source (1) independently is connected by a power switch (9) with each of the n phases in a m×n matrix. First measuring devices (4) for monitoring the m phases (u, v, w) of the source (1) as well as 2nd measuring devices (5) for monitoring the n phases (n1, n2, n3) of the load (3) are provided, and a switching unit (6) is provided, which controls the switching state of the switches (9) depending on the state of the m phases (u, v, w) of the source (1) and of the n phases (n1, n2, n3) of the load (3). This construction allows a particularly quick connection and/or disconnection for increased stability.
Claims32
A device for disconnecting and/or connecting m phases of an alternating voltage providing source from n phases of a load, the device comprising:
- at least one power switch configured and arranged to connect each of the m phases of the source independently with each of the n phases of the load in an m×n matrix;
- first measuring devices configured and arranged to monitor the m phases of the source and second measuring devices configured and arranged to monitor the n phases of the load;
- and
- a switching unit configured and arranged to control the switching state of the at least one power switch depending on the state of the m phases of the source and the n phases of the load.
A method for connecting and/or disconnecting m phases of an alternating voltage current providing source from n phases of a load, the method comprising:
- independently connecting each of the m phases of the source by at least one power switch with each of the n phases of the load in an m×n matrix;
- providing first measuring devices configured and arranged to monitor the m phases of the source, second measuring devices configured and arranged to monitor the n phases of the load, and a switching unit configured and arranged to control the switching state of the at least one power switch depending on the state of the m phases of the source and the n phases of the load;
- and
- opening or closing a maximum of n power switches with said switching unit.
