<p>PURPOSE:To provide an insulating gas-filled composite switch gear that can be more easily maintained and inspected, that enhances earthquake-resistance and environmental harmony, and that reduces the area required for installation. CONSTITUTION:Disconnectors 22a and 22b horizontally installed in one electrode section of a horizontally laid breaker 21a filled with insulating gas are connected in series with six bushings 27c and 27f provided with terminal sections 28b, 28c, 28e, and 28f for connection to a dual bus. A disconnector 22c horizontally installed in the other electrode section is connected in series with three bushings 24c provided with terminal sections 29b and 29c for connection to overhead power transmission lines. Further, these nine terminal sections 28b, 28c, 28e, 28f, 29b, and 29c are installed in parallel with both interphase and interpole directions and mutually orthogonal.</p> |
