<p>A bus section unit comprises a three-phase capacity breaker (5), switches (4a, 4b) and connectors (7a, 7b), and connects two (1,3) of the three gas insulating buses (1,2,3) running in parallel in a dual main bus substation system. The three-phase capacity breaker (5) is located at the side of the buses and one (3) of the buses is held onto another (2) with bolts (11). This arrangement keeps the installation area of the bus section unit minimum and realises mechanical strength against vibration.</p> |
