| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a static apparatus minimized in cost and effectively reduced in stray loss, in a static apparatus, such as a transformer and a reactor, which has a case and is cooled/insulated with an isolation oil.SOLUTION: In a member constituting a case 1, an ordinary steel plate is used for an installation seat 8 and a suspending lug 9 which have a distance relatively far apart from a magnetic core 3 as compared with other members, while non-magnetic stainless is used for materials of an upper side plate 10, a side face side plate 11, a lower side plate 12 and a bottom plate 13, which are members having a distance relatively closer to the magnetic core 3 as compared with other members.
【課題】ケースを有し、絶縁油による冷却、絶縁を行う変圧器やリアクトル等の静止機器において、コストを最小限に抑え、漂遊損を効果的に低減した静止機器を提供する。【解決手段】ケース１を構成する部材であって、磁心３からの距離が他の部材に比べて相対的に離れている取付座８や吊耳９には普通鋼板を用い、磁心３からの距離が他の部材に比べて相対的に近い部材である、上部側板１０、側面側板１１、下部側板１２、底板１３の材料を非磁性体のステンレスとした。【選択図】図２ |
