PROBLEM TO BE SOLVED: To provide a stationary induction apparatus capable of releasing heat of an electrical insulation oil, above the content of the stationary induction apparatus, to the outside of a tank, without having cooling water passage at every position, while suppressing internal pressure variation of the tank.SOLUTION: A stationary induction apparatus housing an iron core-coil assembly in a tank 15, and filled with an electrical insulation oil 18, includes a cover 16 provided above the tank, and a heat radiation mechanism 20 provided in the cover 16. The heat radiation mechanism 20 includes a heat collection part 22 immersed in the electrical insulation oil 18 or floating thereon in the tank 15, a heat radiation part 23 placed on the outside of the cover 16, and a heat transfer part 24 for transferring the heat collected in the heat collection part 22 to the heat radiation part 23. The heat radiation mechanism 20 may include a built-in conservator on the inside of the tank 15.SELECTED DRAWING: Figure 1 【課題】冷却水路を有さずとも、静止誘導機器の中身より上部の電気絶縁油が持っている熱をタンク外に放出することができ、かつ、タンク部の内圧変動を抑制できる静止誘導機器を提供する。【解決手段】鉄心−コイル組立体をタンク１５に収容し、電気絶縁油１８を入れた静止誘導機器であって、タンク上部に設けたカバー１６と、カバー１６に設けた放熱機構２０を備える。放熱機構２０は、タンク１５の内部で、電気絶縁油１８に浸った状態或いは浮いた状態の集熱部２２と、カバー１６の外側に配置される放熱部２３と、集熱部２２で集めた熱を放熱部２３に伝達する伝熱部２４と、を備える。また、放熱機構２０は、タンク１５の内側において、内蔵型コンサベータを備えていても良い。【選択図】図１
