Abstract
Изобретение относитс к электротехнике, в частности к способам изготовлени изол ции электрических машин. Цель изобретени - упрощение технологии и сокращение времени при изготовлении изол ции сердечников полюсов электродвигателей. Способ основан на формовании оболочки из термоусаживающегос полимерного материала с периметром, равным периметру сечени изолируемой части машины, которую нанос т на предварительно нагретую изолируемую часть машины.This invention relates to electrical engineering, in particular, to methods for making insulation of electrical machines. The purpose of the invention is to simplify the technology and reduce the time in the manufacture of insulation of the cores of the poles of electric motors. The method is based on forming a sheath of heat-shrinkable polymeric material with a perimeter equal to the perimeter of the cross-section of the insulated part of the machine, which is applied to the pre-heated insulated part of the machine.
Description
Изобретение относитс к электротехнике , в частности к способам изготовлени изол ции электрических машин .This invention relates to electrical engineering, in particular, to methods for making insulation of electrical machines.
Цель изобретени упрощение технологии и сокращение времени при изготовлении изол ции сердечников полюсов статоров электродвигателей.The purpose of the invention is the simplification of technology and the reduction of time in the manufacture of insulation cores of the stator poles of electric motors.
Способ осуществл етс следующим образом.The method is carried out as follows.
Сердечник полюса нагревают до 160- 200 С (например, от индуктора, надеваемого на сердечник)„ При достижении указанной температуры на сердечник нанос т термоусаживающуюс ленту из синтетических волокон (например, лавсана), имеющую форму замкнутой цилиндрической оболочки,, периметр которой раве периметру сердечника по- люса Лента, нагрева сь, усаживаетс в пределах 6-18% (в зависимости от материала и способа переплетений нитей в ленте), создава прочное и равномерное по толщине электроизол ционное покрытие сердечника полюса.The core of the pole is heated to 160-200 ° C (for example, from an inductor worn on the core). When this temperature is reached, a heat-shrinkable tape of synthetic fibers (for example, lavsan) is applied to the core, having the form of a closed cylindrical shell whose perimeter is equal to the core perimeter pole The tape, when heated, shrinks within 6–18% (depending on the material and the method of weaving the threads in the tape), creating an electrically insulating coating of the pole core that is durable and uniform in thickness.
Нагрев сердечника полюса в пределах 160 - 200°С выбран на основании того, что наибольшее усилие усадки в нит х термоусаживающей ленты из син тетических волокон наблюдаетс в указанном интервале температур. Дл изготовлени оболочек могут быть использованы также полимерные радиа- ционно-модифицированные трубки.The heating of the core of the pole within the range of 160-200 ° C is selected on the basis of the fact that the greatest shrinkage force in the threads of the heat-shrinking tape of synthetic fibers is observed in the indicated temperature range. Polymer radiation-modified tubes can also be used to make the shells.
