LOW PROFILE BLOW-ON FORCE AUTOMATIC SWITCH

摘要

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.

主权项

1. A system of coupled automatic transfer switches, the system comprising:
a first automatic transfer switch and a second automatic transfer switch coupled in a parallel configuration, each of the first automatic transfer switch and the second automatic transfer switch comprising:
a first source bar structured to connect to a first power source;a second source bar structured to connect to a second power source;a stationary bar with a front end and a back end;a first movable bar electrically coupled and rotatably connected to the stationary bar at the front end, wherein the first movable bar contacts the first source bar to provide power from the first power source, wherein the first movable bar is subjected to a first electromagnetic force biasing the first movable bar towards the first source bar, and wherein the first electromagnetic force is induced by current flowing through the stationary bar and the first removable bar; anda second movable bar electrically coupled and rotatably connected to the stationary bar at the front end, wherein the second movable bar contacts the second source bar to provide power from the second power source, wherein the second movable bar is subjected to a second electromagnetic force biasing the second movable bar towards the second source bar, and wherein the second electromagnetic force is induced by current flowing through the stationary bar and the second removable bar; wherein the back end of the stationary bar of the first automatic transfer switch is connected to the front end of the stationary bar of the second automatic transfer switch.
