Abstract:
An electrical load break bushing having a movable tubular conductor therein, engageable with a contact pin of an electrical connector, is arranged to minimize the duration of arc during load-make and load-break operations. A locking member holds the tubular conductor in a first, normally-open position until the contact pin engages the tubular conductor whereon the mated tubular conductor and contact pin assembly move toward a second, normally-closed position. A second contact, adapted to engage the tubular conductor, is supported by the bushing at the second position and is disposed within the dielectric fluid surrounding an electrical apparatus such that an electrical circuit is completed within the dielectric fluid. During a load-break operation, interlock pins prevent the tubular conductor and contact pin from disengaging until the tubular conductor has separated from the second contact whereby the electrical circuit is broken within the dielectric fluid.
