<p>PURPOSE:To diminish a setting area by setting a vertical type breaker in parallel with a main bus line, on one side of the main bus line, and by arranging a current transformers on the upper section of the vertical type breaker, and another one, on the main body section of the main bus line or on the counter breaker side. CONSTITUTION:In close contact with main bus lines 40, 50 arranged vertically and composed linearly, a vertical type breaker 60 is set. A current transformer 7a set between a lower breaker 8 in the sealed vessel 6 of the vertical type breaker 60, and the main bus line 50 is set to surround a conductor 4, and is set on an upper section in the sealed vessel 6 of the vertical type breaker 60. A current transformer 7b set between the breaker 8 and the main bus line 40 is set almost on the same axial line as that of the main body section of the main bus line 40. By a composition in this manner, a setting area could be diminished.</p> |
