Latest Patents
Mitchell's latest patents include an innovative electric circuit breaker comprising parallel-connected vacuum-type circuit interrupters. This design features a plurality of vacuum-type circuit interrupters that are electrically connected in parallel. The interrupters are engineered to open substantially simultaneously during circuit interruption. Each interrupter consists of an evacuated envelope and a pair of relatively movable contacts that create an inter-contact gap, where arcing typically occurs during circuit interruption. The design includes a tubular metal wall portion surrounding the inter-contact gap and a radially extending opening within this wall. The closely adjacent metal wall portions of the interrupters are connected by a short metal tube, which facilitates the passage of arcing products from one gap to another, promoting concurrent arcing during high current interruptions.
