<p>PURPOSE: To obtain a transformer facilities, which can reduce the area of instal lation and can shorten installation period. CONSTITUTION: An oil tank 10 is provided in the protruding pattern toward the lower side surface of a stepdown transformer 14. On the upper surface of the oil tank 10, a gas insulated metal closed switchgear 1 is mounted. In front of the upper part of a case body 2 of the switchgear 1, an insulating bushing 7 is made to protrude. The central conductor of the bushing 7 is connected to an upper terminal 4b of a vacuum circuit breaker 4 for the transformer through a connecting conductor 8B, an instrument current transformer 6 and a connecting conductor 8A inside the case body 2. A lower terminal 4c of the vacuum circuit-breaker 4 for the transformer is connected to the upper end of an insulating bushing 9 through a connecting conductor 8c, a grounding circuit breaker 5 and a connecting conductor 8D. The rear end of the insulating bushing 9 is connected to the primary terminal of the neighboring stepdown transformer 14 through a connecting conductor.</p> |
