  • Switching device with reduced partial discharge and improved triple point characteristics
    Patent number: 11955781
    Abstract: A draw out circuit breaker has a reduced partial discharge in insulation surrounding a primary stab bus. A circular disk plate on one end of the bus includes tapped inserts located at a radial separation distance from the bus. An insulator sleeve surrounding the bus is formed to encapsulate the tapped inserts. Raised embosses on the circular disk plate separate the end portion of the insulator sleeve by a gap distance from the inward facing surface of the disk plate. The increased gap distance reduces formation of a triple point region between the surface of the disk plate and the insulator sleeve, thereby reducing occurrence of partial discharges in the insulator sleeve near the gap.
