摘要： A modified magne-blast vertical racking circuit breaker modified to accept vacuum circuit breakers. The main frame of the magne-blast unit is modified to accept the vacuum breaker operating mechanism and vacuum interrupters, which are connected to the load and line stabs of the magne-blast unit. A mechanism operated cell operator is mounted above the vacuum breaker operating mechanism, and the mechanism is modified to accept an interlock switch which is positioned to engage the switch gear associated with the magne-blast breaker. The unit also includes a surge suppressor mounted on the main frame. The modification method includes the removal of the arc chutes, blowout coils, blowout cores, contact arm assemblies, booster cylinders and main operating crank, and replacing them with the vacuum interrupters; the magne-blast operating mechanism is also replaced by the vacuum interrupter operating mechanism. The surge suppressor is mounted in space previously occupied by the arc chutes such that the modified unit can be received in the magne-blast metal-clad switchgear.
