Изобретение относитс к электро- технгасе и может быть использовано при ремонте электрических машин.The invention relates to electro-technical and can be used in the repair of electric machines.
Цель изобретени - уменьшений объема ремонтных работ и повышение качества ремонта путем сужени зоны ремонта.The purpose of the invention is to reduce the amount of repair work and improve the quality of repair by narrowing the area of repair.
На фиг.1 показан статор; на фиг.2 вид по стрелке А на фиг.1, вид на пакеты сегментов со стороны спинки статора до разборки (поврежденна зона заштрихована)} иа фиг.З - то же, после разборки; на фиг.4 и 5 - расположение :сегментов в разных сло х до и после разборки.Figure 1 shows the stator; Fig. 2 is a view along arrow A in Fig. 1, a view of the segment packets from the side of the stator back prior to disassembly (the damaged zone is shaded)} and fig. 3 - the same after disassembly; Figures 4 and 5 show the arrangement of the segments in different layers before and after disassembly.
Статор состоит из корпуса 1, верхних и Hi-DKHitx нажимных гребегюк 2 И З сердечника 4, закрепленного в корпусе 1 с помощью наборных клиньев 5 типа ласточкин хвост, и обмотки 6 Сердечник 4 собран из сегментов 7 и 8, расположенных в разных сло х и ст нутых шпильками 9. Дл ремонта используютс домкраты 10,The stator consists of case 1, upper and Hi-DKHitx push-buttons 2 and 3 of core 4, fixed in case 1 with the help of type-setting dovetail wedges 5, and winding 6 The core 4 is assembled from segments 7 and 8 located studs with studs 9. Jacks 10 are used for repairs,
Способ осуществл ют следующим образом .The method is carried out as follows.
Дл лгасвццации повреждени удал ют часть стержней обмотки 6 и чист т поврелщенную зону сердечника 4. Под шшние нажимные гребенки 3 устанав- домкраты 10 или другие опорные элементы. Сшмают верхние налсимные гребенки 2, производ т демонтаж необкод1 мого количества наборных клипьец 5 и ст жпьгх шпилек 9 в зоне повреждени . Далее производ т демон- та;к части сердечника 4 с захватом всей зоны иовре;кдени (фиг.З). В пазы неповрежденной части сердечншса вставл ют новые клш1ь , а в пазы зуб- довой зоны сборочные калибры. Затем в образовавшуюс полость сердечникаIn order to compensate for the damage, a part of the winding rods 6 is removed and the turned-up zone of the core 4 is cleaned. Underneath the pressure combs 3, the jacks 10 or other supporting elements are installed. The upper nalcimetals 2 are sewn, the necessary number of compressed clips 5 and st pins 9 are disassembled in the damage zone. Next, a demon is manufactured; to a part of the core 4 with the capture of the entire area of the Ivre; kdeni (Fig. 3). The new grooves are inserted into the grooves of the intact part of the heart, and the assembly gauges are inserted into the grooves of the tooth zone. Then into the formed cavity of the core

4 послойно устанавлршают новые сегменты , при этом постепенно подава наборные клинь и калибры. После этог го пажимные гребенки 2 и шпильки 9 став т на свое место. Производ т под- прессовку собранного участка сердечника , например, с помощью шпилек 9, после чего устанавливают обмотку 6,4 layer-by-layer install new segments, while gradually supplying composing wedges and calibers. After this, the tongue combs 2 and the studs 9 are put in place. The assembled section of the core is pressed, for example, using studs 9, after which winding 6 is installed,
Предлагаемый способ позвол ет сохранить объем paMoHTiibix работ и повысить качество ремонта, так как прре- шихтовке подвергаетс минимально необходима зона сердечника.The proposed method allows preserving the amount of paMoHTiibix work and improving the quality of repair, since the pre-charge is subjected to the minimum required core area.
