Integrated transformer sectionalizing switch assembly

Abstract

An integrated transformer-sectionalizing switch assembly including a transformer module having a low profile feeder module mounted on and connected to the transformer module. The feeder module including two pair of circuit breakers mounted in side by side relation on each side of the feeder module with each pair of circuit breakers in back to back relation with the other pair of circuit breakers. A bare bus network is used to interconnect the secondary phase bushings to the circuit breakers. The bus network including three bus bars, each bus bar being connected to a phase busing. Each bus bar also including a phase connector connected to each circuit breaker. The phase connectors on each bus bar being arranged to correspond to the location of the same phase contact on each circuit breaker so that the circuit breakers can be interchanged. The feeder module is also provided with a compartment for a low potential transformer assembly.
