AUTOMATIC TRANSFER SWITCH

摘要

Aspects of the present disclosure involve systems, methods, and the like, for an automatic transfer switch (ATS) of a power system. The ATS allows for switching between two or more power systems while preventing back-feeding of the power systems. To provide the safety features of the ATS, a safety circuit and control board may be implemented with the magnetic latching relays to control the actions of the latching relays and provide the switching function of the ATS. In one particular embodiment, the safety board comprises one or more electromechanical relays positioned between the controlling electronics of the control board and the magnetic latching relays. The safety board design contains measures to ensure it still functions if one of the disconnect switches is not connected, if one of the connections to a first load phase, a second load phase or neutral is lost and if the main control board is not connected.

主权项

1. A system for an automatic transfer switch, the system comprising:
a first power source connection electrically connected to a first power source; a second power source connection electrically connected to a second power source; a first electromagnetic latch connected between the first power source and a load; a second electromagnetic latch connected between the second power source and a load; a safety circuit in electrical communication with the first electromagnetic latch and the second electromagnetic latch, the safety circuit configured to provide one or more safety features for the switch from the first power source to the second power source; and a control circuit in electrical communication with the safety circuit, the control circuit configured to provide one or more control signals to control the operation of the first electromagnetic latch and the second electromagnetic latch.
