Electric circuit breaker with improved safety features
A recently granted patent (Publication Number: US11996252B2) discloses an innovative electric circuit breaker design. The circuit breaker includes an electrical conductor with a switch that separates terminals in response to a current cutoff order. An arc extinguishing chamber is configured to receive the separated conductor portion, with a fuse connecting the terminals post-switch trip. A unique connection device with a gate is designed to break only when specific thresholds related to temperature, pressure, or electrical arc intensity in the chamber are exceeded, connecting the fuse electrode to a terminal.
Furthermore, the patent details additional features such as an insulating gate separating electrodes in the arc extinguishing chamber, walls that melt or deform based on temperature or pressure thresholds, and a control circuit with sensors for monitoring conditions inside the chamber. The circuit breaker also includes an additional fuse with its own gate and an extra electrical conductor insulated from the chamber. The connection device features a movable part that connects the fuse electrode to a terminal when activated, with the gate designed to break under predefined conditions. Overall, the patent showcases a sophisticated electric circuit breaker design with multiple safety mechanisms and innovative features to enhance performance and reliability, including the use of a pyrotechnic switch for tripping.
