MITIGATING AN EFFECT OF A DOWNSTREAM FAILURE IN AN AUTOMATIC TRANSFER SWITCHING SYSTEM

摘要

A system may comprise a first switch connected to an output of a first power source, a second switch connected to an output of a second power source, a first sensor connected to an output of the first switch, a second sensor connected to an output of the second switch, a third switch connected to the first sensor and the second sensor and connected to a load, and a control device connected to the first switch, the second switch, the first sensor, the second sensor, and the third switch.

主权项

1. A device, comprising:
one or more processors to:
detect a failure condition in a system that includes a load and at least four power sources,
the load being powered by the system, andthe system including at least a first switch and a second switch,
the first switch to selectively power the load using a first electrical current provided by a first power source, of the at least four power sources, or using a second electrical current provided by a second power source of the at least four power sources, andthe second switch causing the load to be powered using a third electrical current or a fourth electrical current, the third electrical current and the fourth electrical current being provided by a third power source and a fourth power source, respectively, of the at least four power sources;determine that the failure condition is associated with a failure at the load; andtransmit a signal based on determining that the failure condition is associated with the failure at the load,
the signal causing the first switch to maintain a state of the first switch when the first switch receives the signal,
the state being a first state when the first switch powers the load using the first electrical current, orthe state being a second state when the first switch powers the load using the second electrical current.
