<p>PURPOSE:To reduce the height of a unit by making two sets of breakers. located on right and left sides, of three sets constituting the unit to be of vertical type and a central breaker to be of horizontal type. CONSTITUTION:A gas-insulated switching apparatus comprises main bus-lines 1, 2, breakers 3-5, breakers 9-16, current transformers 45-52, ground switches 25-34 and voltage transformers 61, 62. This apparatus is mounted on bases 77-79 and the main bus-lines 1, 2 are located below the breakers 3, 5, respectively. The breakers 3, 5 are of vertical type and the central breaker 4 is of horizontal type. The conductors led out of the connections 301, 501 of the breakers 3, 5 are connected to cable terminals 65, 66, respectively, on the load sides and to the connections 401, 402 of the breaker 4. The connections 302, 502 of the breakers 3, 5 are connected to the main bus-lines 1, 2, respectively.</p> |
