摘要： The tubular vapor shield of a vacuum interrupter is secured to the ceramic by a shield mount which includes a split ring seated in a circumferential groove formed in the inner surface of the ceramic. The tubular vapor shield is secured to the split ring by a connection which includes a circumferential flange brazed to the shield and a braze ring which is wedged in an annular gap between the flange and the vapor shield and which melts when heated in a vacuum oven to braze the split ring to the vapor shield and the flange. In another embodiment, the flange has a radial outward rim which seats on the split ring. In an additional embodiment, the connection between the split ring and the vapor shield includes a circumferential shield groove in the outer surface of the vapor shield in which the split ring is also seated and optionally secured by a braze. In yet another embodiment, an additional split ring seated in a circumferential groove in the outer surface of the vapor shield is brazed to the split ring seated in the groove in the ceramic.

摘要： A vacuum arc interrupter that includes a vacuum chamber assembly and a pressure chamber assembly. The vacuum chamber assembly has a first conductor coupled to a power line, a non-conductive housing and a seal cup. The pressure chamber assembly has a second conductor coupled to a ground, a pressure chamber and a bullet assembly. The pressure chamber assembly is disposed adjacent to the vacuum chamber assembly. The bullet assembly is disposed in the pressure chamber and is structured to move between a first position and a second position. The bullet assembly has a metal lance with a blade portion. The blade portion is structured to puncture the seal cup.
