HYBRID CIRCUIT BREAKERS

摘要

Hybrid gas circuit breakers comprising a main breaker tank having an interrupter assembly positioned therein, bushing support nozzles laterally extending from the breaker tank, disconnect switches coupled to and extending generally upwardly or vertically from the bushing support nozzles, and bushings assembled to the disconnect switches. In addition, bushing current transformers (BCTs) are assembled on the bushing support nozzles adjacent the breaker tank instead. The lateral positioning of components results in a low assembled height permitting shipping of a fully assembled and tested unit for voltage ratings up to and including 362 kV.

1. A hybrid gas circuit breaker comprising:
a tank, a mechanical interrupter positioned within the tank, first and second bushing support nozzles that protrude laterally from the tank, first and second disconnect switches to and extending upwardly from the first and second bushing support nozzles, intake and exit bushings assembled to the first and second disconnect switches, and first and second bushing current transformers (BCTs) assembled on the first and second bushing support nozzles adjacent the tank.
