Abstract
Systems of automatic transfer switches (ATS) are disclosed herein. One apparatus includes at least two automatic transfer switches coupled together. Each automatic transfer switches has contacts to couple a power source to a load. For each switch, an electromagnetic force biasing the contacts to each other is present if an electrical current flows through the switch. The automatic transfer switches may be on separate cassettes or on a single cassette. The power source of each switch may be the same or different.
Claims20
A system of coupled automatic transfer switches, the system comprising:
- a stationary bar;
- and
- a plurality of automatic transfer switches on the stationary bar, each of the plurality of automatic transfer switches comprising:
- a source bar structured to connect to a corresponding power source;
- and
- a movable bar electrically coupled and rotatably connected to the stationary bar, wherein the movable bar contacts the source bar to provide power from the corresponding power source, wherein the movable bar is subjected to an electromagnetic force biasing the movable bar towards the source bar, and wherein the electromagnetic force is induced by current flowing through the stationary bar and the movable bar,
- wherein the movable bars of the plurality of automatic transfer switches are disposed at a same side of the stationary bar.
A system comprising:
- a generator;
- and
- a plurality of automatic transfer switches on a stationary bar, each of the plurality of automatic transfer switches comprising:
- a source bar structured to connect to a corresponding power source of a plurality of power sources, wherein the plurality of power sources comprises the generator;
- and
- a movable bar electrically coupled and rotatably connected to the stationary bar, wherein the movable bar contacts the source bar to provide power from the corresponding power source, wherein the movable bar is subjected to an electromagnetic force biasing the movable bar towards the source bar, wherein the electromagnetic force is induced by current flowing through the stationary bar and the movable bar, and wherein the movable bars of the plurality of automatic transfer switches are disposed at a same side of the stationary bar.
