COMPUTER-CONTROLLED CIRCUIT BREAKER ENERGY MANAGEMENT ARRANGEMENT HAVING RELIABLE MEMORY AND CLOCK

摘要

An energy management load panel arrangement includes a load panel enclosure (10) having a plurality of circuit breakers (20), each of which opens and closes in response to a control signal so as to interrupt an associated current path. A microcomputer (120) generates the control signals to control the position of the circuit breakers (20) and their associated current paths, and a volatile memory circuit, for example, RAM (126), stores time-event data which is used to indicate when the control signals should be generated. A charged electronic double-layered capacitor (144) is coupled to the volatile memory so that, in the event of a power outage, operating power is provided to the volatile memory for extended periods of time. A real time clock circuit (138) is used to track the time, and the charged electronic double-layered capacitor is coupled to the real time clock circuit (138) so that it also continues to operate during a power outage.
