Distribution line based on double bus wiring
2014
The utility model discloses a distribution line based on double bus wiring. The distribution line comprises a first bus, a second bus, a first main transformer circuit, a second main transformer circuit, a third main transformer circuit and a number of output circuits. The first main transformer circuit only accesses the first bus. The second main transformer circuit only accesses the second bus. The third main transformer circuit accesses the first bus and the second bus. A number of output circuits respectively access the first bus or the second bus. The first bus and the second bus are connected through a switch circuit. When the distribution line works, if the first bus needs to quit running, the first main transformer circuit correspondingly quits running; the connection of the third main transformer circuit and the first bus is cut off; the third main transformer circuit continues to be connected with the second bus and normally runs, so as to ensure a load demand; if the second bus needs to quit running, the second main transformer circuit correspondingly quits running; the connection of the third main transformer circuit and the second bus is cut off; and the third main transformer circuit continues to be connected with the first bus and normally runs, so as to ensure the load demand.
