Brief description of embodiments of a sealed closure of the vacuum and the oil in the construction of the transformers as well as the shutter to be carried out after this

摘要

This process uses an electrode - screen 9 provided with an insulating layer of the fixing element 10. According to the process, it covers the electrode - screen 9 of a first layer 11 of the board structured to at least over the major part of its length, it surrounds the first layer of a part of a second layer similar 12 whose shape corresponds to the shape desired of the attachment element 14 is dried the two layers under vacuum and impregnated under vacuum of a certain enzymes in the oil and resin hardened when cold, then it covers the thickness impregnated 11, 12 on each of the dimensions external has discovered of at least one insulating layer 14, 15, 16. / p & & p & the invention is applicable in particular to the large transformers in the oil.
