<p>PURPOSE:To simplify the shape of the connecting bus-bar between a main bus- bar and a lightning arrester longer than the installation height of the main bus-bar, by making the main bus-bar of the connecting bus-bar and its axis uniting the connection with an arrester parallel, and vertical against the main bus-bar, and arranging the arrester on the same axis with the axis of the connecting bus-bar. CONSTITUTION:Arresters 8a and 8b are arranged horizontally and up and down in three dimensions, and connected to upper and lower bus-bars 1a and 1b through the medium of T-shaped connecting bus-bars 14a and 14b. The axial length of the main bus-bars 1a and 1b required for connecting the arresters 8a and 8b has only to be the length of connections 13a and 13b. Besides, it becomes possible to use T-shaped connecting bus-bars 14a and 14b of simple shapes as connecting bus-bars by making the arresters 8a and 8b horizontal and arranging them at heights of the upper and lower main bus-bars 1a and 1b. In addition, the ground-side end of the arrester 8b becomes nearer to the main bus-bars than that of the arrester 8a by making the length of the T-shaped connecting bus-bar 14b shorter than the T-shaped connecting bus-bar 14a by a specified length, and this length is utilized as a space for drawing.</p> |
