Virtual Electronic Circuit Breaker

摘要

A virtual electronic circuit breaker having an electrical relay and a control circuit, the control circuit including a load and wire protection (“OC”) detection unit, a microprocessor and a driver. The OC detection unit is configured to monitor a power flow and the electrical relay is effective to control it. The driver is effective to cause the relay to stop the power flow upon receipt of a deactivation command. The OC detection unit is effective to cause the driver to receive a deactivation command if the OC detection unit senses that a short circuit condition or an overload condition exists. The microprocessor of the control unit is configured so as to be capable of, at least, receiving input from the OC detection unit and sending output to the driver.

主权项

1. A virtual electronic circuit breaker, comprising:
an electrical relay effective to control an amount of power flow; a solid state switch in parallel with the electrical relay; a control circuit, having a single Load and Wire Protection (“OC”) detection unit, a microprocessor and a driver; said driver effective to cause said relay to stop said power flow upon receipt by the driver of a deactivation command; said single OC detection unit configured to both monitor said power flow and effective to cause said driver to receive a deactivation command in response to a detection, by said single OC detection unit, that an overload condition exists; and said microprocessor configured to be capable of receiving input from said single OC detection unit, sending output to said driver, and configured to be capable of receiving a “reset” command, a “collar” command, an “on” command, and an “off” command from a control panel.
