<p>PURPOSE:To provide a gas-insulated switchgear which can ensure the insulating distance between bushings and between overhead transmission lines even when a dead-end tower is arranged so as to be tilted with reference to a main bus and which can miniaturize the main bus and a connecting bus. CONSTITUTION:Three single-phase connecting buses 3 are arranged in parallel in directions perpendicular to a three-phase bus 1. Ends, on one side, of the respective connecting buses 2 are connected to respective phases for the three- phase bus 1. Bushings 3 are installed respectively at ends, on the other side, of the connecting buses 2. Lengths of the connecting buses 2 are set in such a way that the bushings 3 are arranged in directions parallel to a dead-end tower 4. Overhead transmission lines 5 are connected to the bushings 3, and the overhead transmission lines 5 are held by insulators 6 for the dead-end tower 4 so as to be extended further to other power installations.</p> |
