<p>PROBLEM TO BE SOLVED: To reduce the length of a main bus and ensure the space around a breaker, by connecting the connection part for a leading-out part of a transmission line unit and the connection part of the transmission line unit and the main bus, by using annular tubes. SOLUTION: In the case of double bus system, a main bus 1 and a main bus 2 are arranged in parallel with each other. Transmission line units 3, 4, 5, 6 are arranged on the transmission line side. Transformer units 9, 10, 11, 12 are arranged on the transformer side. As shown by a part A, a part of an annular tube is applied to the connection parts of the transmission units 3, 6 and the transformer units 9, 11 with the main bus 1. As shown by B, a part of an annlar tube is applied also to the connection parts of the transmission line units 3, 6 and the transmission line, and the transformer units 9, 10 are connected with the connection part of a transformer. Thereby the length of the main buses 1, 2 can be reduced, to the leading-out part of the transmission line and the leading-out part which are arranged maintaining necessary insulating distance in the air. Further the occupied area containing the base of a gas insulation switchgear can be reduced.</p> |
