摘要： A vacuum circuit breaker (VCB) assembly includes a single motor configured to rotate at least one rotor, a VCB having a breaking mechanism configured to control current flow through the VCB and a first electromagnetic clutch configured to selectively engage the at least one rotor with the breaking mechanism to charge the breaking mechanism. The VCB assembly also includes an undercarriage configured to support the VCB assembly and to move the VCB assembly from a first position to a second position and a second electromagnetic clutch configured to selectively engage the at least one rotor with the undercarriage to drive the undercarriage.

摘要： A spout for a connection between a bus bar and a circuit breaker in switchgear includes a housing and a fixed contact. The housing is formed of insulative material and includes a tubular body having an inner cavity and a radial first ventilation opening, a base portion having a first longitudinal opening, and a fixed contact receiving portion having a second longitudinal opening. The fixed contact is formed of a conductive material, has an outer contact surface exposed through the second longitudinal opening, and forms a portion of an outer surface of the spout. A switchgear includes a wall dividing a circuit breaker compartment from a bus bar compartment, and the base portion of the spout is securable to the wall. A method of increasing heat dissipation within switchgear using the spout includes securing a bus bar to the outer contact surface, and dissipating heat through the radial ventilation opening.
