Abstract
A three-phase encapsulated high-voltage circuit breaker for outdoor use, whose interrupter units are arranged in a tubular switch housing which is arranged horizontally. Phase connections of the interrupter units are passed vertically and together through in each case one connecting flange, with each connecting flange having an associated splitting module which is fitted with outdoor bushings. Each phase connection has an associated current transformer, and these items are located within the housing and are attached to the respective splitting module.
Claims2
