为了适用于引进德国 ＭＷＢ公司的无局放试验变压器器身干燥的要求，我们研制了真空热风干燥浸油设备。本文详尽的叙述了该设备的构成、真空热风干燥浸油工艺以及讨论了真空热风干燥与保温之间的关系。通过三年来的运行证明该设备满足了德国ＭＷＢ公司的无局放试验变压器器身干燥的要求，得到了该公司的认可，省掉了从国外进日真空热风干燥设备，这样便节约了大量外汇，而且为将来即将研制的φ３６００ｍｍ真空热风干燥设备积累了宝贵的经验，使我国的真空热风干燥设备进入了８０年代的行列。
In order to apply to the request of German MWB company without PD test transformer body drying requirements, we have developed a vacuum hot air drying oil immersion equipment. This article describes in detail the composition of the equipment, vacuum hot air drying oil immersion process, and discusses the relationship between vacuum hot air drying and insulation. After three years of operation proved that the equipment to meet Germany’s MWB’s non-PD test transformer body drying requirements, has been recognized by the company, eliminating the need to enter Japan vacuum hot air drying equipment from abroad, thus saving a lot of foreign exchange , But also for the future development of φ3600mm vacuum hot air drying equipment has accumulated valuable experience, so that China’s vacuum hot air drying equipment into the ranks of the 80’s.
