<p>PURPOSE: To reduce the total height of a switchgear and improve the vibration resistance by a method wherein 1st, 2nd and 3rd machine units are arranged on a horizontal 1st straight line and a 1st bus-bar is provided on a horizontal 2nd straight line which is adjacent to the respective machine units and on the side surfaces of the respective machine units and a 2nd bus-bar is provided above the 1st bus-bar. CONSTITUTION: A 1st machine unit 601d, a 2nd machine unit 602d and a 3rd machine unit 603d which are respectively composed of breakers, current transformers and disconnectors which are connected in series to each other are arranged in this order on a 1st straight line on a horizontal projected plane. A 1st bus-bar 100d is provided on a horizontal 2nd straight line adjacent to the respective machine units 601d, 602d and 603d and on the side surfaces of the respective machine units 601d, 602d and 603d. A 2nd bus-bar 200d is provided above the 1st bus bar 100d and on the side surfaces of the machine units 601d, 602d and 603d. With this constitution, the total height can be reduced and the vibration resistance can be improved.</p> |
