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.

摘要： The toggle mechanism of a circuit breaker is connected at one end to the pivoted contact arm and at the other end to a pivoted latch lever which is engaged to latch the toggle mechanism by a latch member pivoted for movement in a plane perpendicular to the plane of the toggle mechanism. The latch member serves as an armature for a trip motor energized by a trip circuit responsive to an arc fault and/or a ground fault to unlatch the toggle mechanism and trip the circuit breaker open. The latch member is also tripped by a helical bimetal responsive to persistent overcurrents and coupled to the latch member through an ambient compensator bimetal cantilevered from the latch member. A flexible shunt connected between the helical bimetal and contact arm passes through an extension of the magnetic circuit of the trip motor to generate a magnetic field of sufficient strength to trip the latch member instantaneously in response to a short circuit.
