Description
図1は、本発明の一実施の形態による油入静止誘導機器としての油入変圧器を示す縦断面図である。
絶縁油入りのタンク1内には、支持台16上に締付金具5,5a,5bや、鉄心2,4や、三相の巻線6U,6V,6Wが保持されている。タンク1の上部には高圧側ブッシング7U,7V,7Wおよび低圧側ブッシング8U,8V,8Wが取り付けられており、巻線6U,6V,6Wの高圧巻線は高圧側ブッシング7U,7V,7Wの中心導体にそれぞれ接続され、また巻線6U,6V,6Wの低圧巻線は低圧リード線によって低圧側ブッシング8U,8V,8Wの中心導体にそれぞれ接続されている。巻線6U,6V,6Wの下部からは絶縁被覆を施した結線用端子リード線14が導出され、この結線用端子リード線14は絶縁支持部材15に支持されながら立ち上げられ、その後、低圧リード線と共に束ねられている。

Claims (1)
- 絶縁油入りのタンク内に配置した巻線の低圧側と、前記タンクの上部に取り付けた低圧側ブッシングの中心導体間を絶縁被覆を施した低圧リード線によって接続して構成した油入静止誘導機器において、前記タンクの上部の絶縁油中にほぼ板状の放熱板をほぼ鉛直に配置し、前記放熱板は、前記巻線の真上でない位置に配置すると共に、前記タンクの側部内壁面側に偏寄して前記側部内壁面にほぼ平行に配置し、この放熱板と前記中心導体間を絶縁被覆を施したブッシング側低圧リード線によって接続し、前記放熱板と前記巻線の低圧側間を前記ブッシング側低圧リード線の前記絶縁被覆よりも高耐熱性の絶縁被覆を施した巻線側低圧リード線によって接続したことを特徴とする油入静止誘導機器。
