THERMAL FAILURE PREDICTION MODULE AND METHOD FOR SOLID STATE CIRCUIT PROTECTION DEVICE
A system and method are provided for protecting semiconductor components from thermal failure in an electronic circuit interrupter. The electronic trip unit (ETU) is configured to determine what range of current the detected current signal corresponds to, out of several ranges categorized as being either non-fault/normal, non-severe fault, and severe fault. The ETU then selects a mode of operation in which to operate based on the determined range of current. In modes of operation corresponding to a fault condition, the ETU monitors certain characteristics of the current such as magnitude and/or rate of rise, and if the aforementioned current characteristics exceed a specified threshold for a minimum interval of time, the ETU will trip the electronic interrupter. If, however, the aforementioned current characteristics fall below the specified threshold prior to the minimum interval of time elapsing, the ETU will not trip the electronic interrupter.

An acoustic sensing system for detecting movement of an ultra-fast actuator in a hybrid circuit interrupter is disclosed. The system comprises a number of acoustic sensors structured to perform active or passive position sensing. For active sensing, the sensors emit sound waves toward a number of targeted portions of the actuator moving assembly and detect the positions of the targets based on acoustic signals reflected back to the sensors by the targets. For passive sensing, the sensors detect acoustic wavelets generated as a result of the moving assembly components moving during opening and closing operations. Acoustic signals can propagate through air or solids and thus the sensors can be mounted in a variety of locations within the circuit interrupter. Acoustic sensors are particularly well-suited for the circuit interrupter environment, as they are resilient to the environmental and external factors, such as dust, that can affect the performance of non-acoustic sensors.

FAULT LOGIC BASED OPERATING SYSTEM FOR ONE OR MORE DISCONNECTS IN A CIRCUIT BREAKER, WITH PROVISION OF LIMITED AUTOMATIC SELF-RESET AND/OR RESET BY SOFTWARE APPLICATION
A circuit breaker with at least one disconnect mechanism and a smart monitoring system implements nuanced fault logic in order to minimize disruption to operation of the circuit breaker under a fault condition, and enables the circuit breaker to address nuisance or low severity faults separately from load switching. Under low severity or nuisance fault conditions, the smart monitoring system temporarily disconnects affected loads from the power supply rather than tripping the entire circuit breaker so that the loads can be reconnected to the power supply if the fault condition resolves within a short amount of time. In addition, the disconnect mechanism(s) that are used to temporarily disconnect the load(s) are configured to be re-closed after opening without requiring manual intervention. In high severity fault conditions, the smart monitoring system actuates tripping of the entire breaker, requiring manual re-closing of the circuit breaker.
