<p>PURPOSE:To miniaturize the entire body of the title switchgear and, at the same time, to lower the position of its center of gravity by connecting main bus side equipment to the upper and intermediate lead-wire terminal sections of the container of a circuit breaker which has vertically arranged three lead- wire terminal sections and is installed vertically. CONSTITUTION:An upper, intermediate, and lower lead wire terminal sections 2-4 are provided in the vertical direction on the side face of the container of a circuit breaker 1 vertically installed on a mounting base and main buses 12 and 15 are connected to the upper and intermediate lead-wire terminal sections 2 and 3 respectively through earthing switchgears 10 and 13 for work. A cable head 8 is connected to the lower lead-wire terminal section 4 through an earthing switchgear 5 for work, disconnecting switch 6 for line, earthing switchgear 7 for line, and connecting bus 17 and a transformer 9 for gauge is connected below the connecting bus 17. A cable cone 16 is housed in the cable head 8.</p> |
