Description
Изобретение относитс к электромашиностроению и может быть использовано при изготовлении обмоток крупных электрических машин.The invention relates to electrical engineering and can be used in the manufacture of windings of large electric machines.
Известен способ изготовлени обмоток статора , сущность которого заключаетс в том, что на пазовые и лобовые части катушек нанос т непрерывную изол - цию из сухих стекпослюдинитовых лент, затем. катушки укладывают в статор и пропитывают эпоксидным компаундом Методом вакуумнагнетательной пропитки или катушки пропитывают вне статора, затем укладывают в статор незапеченными (мокрыми), после чего катушки запекают в статор.A known method of manufacturing the stator windings, the essence of which lies in the fact that continuous insulation of dry stekpluedinitovyh tape, then applied to the groove and front parts of the coils. The coils are placed in the stator and impregnated with epoxy compound. Using a vacuum-pressure impregnation method or the coils are impregnated outside the stator, then placed into the stator unbaked (wet), after which the coils are baked into the stator.
Основным недостатком такого способа изготовлени вл етс абсолютна неремон- топригодность обмоток в процессе эксппу- атации, т, е, нет возможности замены JQ в обмотке одной вышедшей из стро .катушки без повреждени остальных.The main disadvantage of this method of manufacture is the absolute inconvenience of the windings during the operation, t, e, there is no possibility of replacing JQ in the winding of one failed coil without damaging the others.
Известен способ изготовлени обмоток статора 2, предусматривающий наложение пропитанных стеклослюдинитовых материалов на пазовые части катушек и наложение эластичных материалов в лобовых част х катушки.A known method of manufacturing the windings of the stator 2 involves the imposition of impregnated glass mica materials on the grooves of the coils and the imposition of elastic materials in the front parts of the coil.
Недостатком этого способа изготовлени термореактивной изол ции на катушках вл етс необходимость гидростатической опресиОБКи запечки катушек с изол цией в битумном компаунде.The disadvantage of this method of manufacturing thermosetting insulation on coils is the need for hydrostatic testing and baking of coils with insulation in a bituminous compound.
Наиболее близким к описьгоаемому вл етс способ изготовлени катушечных обмоток электрических машин 7, включающий пропитку головок лобовых частей катушек эластичным разделительным материалом , намотку сплошной изол ции из сухих слюдосодержащих лент, пропитку корпусной изол шш головок лобовых частей неадгезирующим разделительным материалом , укладку катушек в пазы статора и пропитку всего статора в синтетическом компаунде.The closest to the described is a method of manufacturing the coil windings of electric machines 7, including impregnation of the heads of the coil frontal parts with an elastic separation material, winding continuous insulation from dry mica-containing tapes, impregnating the body insulation of the heads of the frontal parts with non-adhesive separating material, laying the coils into the stator grooves and impregnation of the entire stator in a synthetic compound.
Основным недостатком описанного cn jсоба , в случае ремонта, вл етс необходимость разрезать катушку в головкеThe main disadvantage of the described cn ja, in the case of repair, is the need to cut the coil in the head
