<p>PROBLEM TO BE SOLVED: To reduce the scale of electric power facilities and form an apparatus at the identical voltage level by disposing one terminal for connecting both breakers above the other terminal. SOLUTION: Breakers 3a, 3b are connected above the other terminal through a connection bus 3c. The breaker 3a is connected to main buses 3g, 3h through a connecting bus 3d and disconnectors 3e, 3f, and a grounding switch 3i, and instrument transformers 3j, 3k are connected to the other breaker. Thus the terminal for connecting the two vertical breakers 3a, 3b is disposed above the other terminal, therefore, in the case the switch 3i and the transformers 3j, 3k are connected, it is possible to make effective use of a space for disposing apparatus, and take an action without increasing a site necessary to install the apparatuses.</p> |
