Electric circuit breaker with temperature and pressure-sensitive connection device
The patent US11996252B2 describes an innovative electric circuit breaker designed to enhance safety and functionality during electrical faults. The circuit breaker features an electrical conductor with two terminals and a switch that separates these terminals when a current cutoff order is issued. An integral arc extinguishing chamber is included, which receives a portion of the electrical conductor once the switch is tripped. A fuse is connected between the terminals post-trip, and a unique connection device is incorporated. This device includes a gate that only breaks under specific conditions—such as exceeding predefined thresholds for temperature, pressure, or electrical arc intensity—allowing the fuse to connect to the electrical conductor.
Further claims detail the construction and operation of the circuit breaker, including the use of an electrically insulating gate that can be designed to melt or deform under certain conditions, facilitating the connection of the fuse. The design may include additional features such as a control circuit with sensors to monitor conditions within the arc extinguishing chamber, ensuring timely activation of the fuse. The patent also outlines the possibility of incorporating an additional fuse and various configurations for the insulating gate, which can be made from materials that respond to temperature and pressure changes. Overall, this patent presents a comprehensive approach to improving circuit breaker technology, focusing on safety mechanisms that respond dynamically to electrical faults.
