<p>PURPOSE:To reduce the area of a site, and to obtain a low-cost gas-insulated switch by arranging a disconnector, etc., to the upper section of a circuit breaker and disposing first and second main buses on a center line in the longitudinal direction of the disconnector annexed to the circuit breaker. CONSTITUTION:First and second main buses 1, 2 are arranged mutually in approximately parallel, and first, second and third circuit breakers 3-5 are disposed mutually in parallel between the first and second main buses 1, 2 so as to cross at a right angle with center lines in the longitudinal direction of the first and second main buses 1, 2. Connecting buses 16, 17 run parallel with the first and second main buses 1, 2 and are held by the first and second main buses, and are disposed to the upper sections of the circuit breakers 3, 4, 5, and center lines in the longitudinal direction of the main buses cross at a right angle with the center lines in the longitudinal direction of disconnectors 7, 8, 9, 10.</p> |
