<p>PURPOSE:To decrease composing members and to reduce a site area by setting the axes of upper connection ports of two breakers mounted perpendicularly to a main bus to the same height to be arranged on both sides of the bus, and providing a disconnector for disconnecting and connecting a phase shifting transformer between the upper ports. CONSTITUTION:Lower connection ports of breakers 5a, 5b mounted perpendicularly to both sides of main buses 1a, 1b are connected to the main buses 1a, 1b through instrument CTs 4a, 4b, disconnectors 2a, 2b and grounding switches 3a, 3b. The heights of the axes of the upper connection ports are set to the same, the CTs 4a', 4b' and the switches 3a', 3b' are connected, and disconnectors 7a, 7b for disconnecting a phase shifting transformer 9 and a bypass disconnector 2ab are connected through connecting buses 6a, 6b. The transformer 9 is connected to the disconnectors 7a, 7b through a conduit bus 8. Thus, a device for easily disconnecting and connecting the phase shifting transformers is built on a narrow site by the use of less composing members.</p> |
