초록 ▼

An automatic transfer switch having two sets of phase switches, one set for connection between a normal source of power and a load, and the other set for connection between an emergency power source and the load. The transfer switch includes two pairs of neutral switches, one pair for connection in parallel between the normal source neutral and the load neutral, and the other pair for connection in parallel between the emergency source neutral and the load neutral. The phase switches can operate to provide an “open transition”transfer, wherein the phase switches connecting the load to one source open before closing of the phase switches which connect the load to the other source, or a “closed transition”transfer, wherein the phase switches connecting the load to one source open after closing of the phase switches which connect the load to the other source. Prior to transfer operation, the pair of neutral switches corresponding to the closed set of phase switches are closed and the pair of neutral switches corresponding to the open set of phase switches are open. During transfer of the load, whether by open or closed transition transfer, one neutral switch of each pair are closed before the open set of phase switches close and those neutral switches remain closed until after the closed set of phase switches opens. Thereafter, the pair of neutral switches which had originally been open are both closed, and the pair of neutral switches which had originally been closed are both opened.

대표청구항 ▼

An automatic transfer switch for transferring an electrical load from a normal source of electric power to an emergency source of electric power, and vice versa, comprising: (a) a first set of phase switches for connection between the normal source and a load, (b) a second set of phase switches for connection between the emergency source and the load, (c) first and second neutral switches for connection between a normal source neutral conductor and the load neutral conductor, (d) third and fourth neutral switches for connection between an emergency source neutral conductor and the load neutral conductor, (e) actuator means for opening and closing said first set of phase switches, (f) actuator means operable independently of said actuator means (e) for opening and closing said second set of phase switches, (g) means responsive to operation of said actuator means (e) for opening said first neutral switch and closing said third neutral switch when said first set of phase switches opens, and for closing said first neutral switch and opening said third neutral switch when said first set of phase switches closes, and (h) means responsive to operation of said actuator means (f) for opening said second neutral switch and closing said fourth neutral switch when said second set of phase switches closes, and for closing said second neutral switch and opening said fourth neutral switch when said second set of phase switches opens.
