Description
Изобретение относитс к способам изолировани секций обмоток высоковольтных аппаратов, в частности трансформаторов.The invention relates to methods for isolating winding sections of high-voltage apparatus, in particular transformers.
В насто щее врем элементы высоковольтных аппаратов, работающие в масле, изолируютс последовательным многослойным покрытием киперной лентой, лакотканью, телефонной или другой тонкой бумагой. Наиболее распространено изолирование бумагой, при этом ее слон скрепл ютс смолой. Каждый слой проглаживаетс гор чими утюжками . Эти операции выполн ютс вручную и вл ютс очень трудоемкими.Currently, elements of high-voltage apparatuses operating in oil are insulated by sequential multi-layer coating with keeper tape, varnished cloth, telephone or other thin paper. The most common is paper insulation, with its elephant fastened with resin. Each layer is ironed with hot irons. These operations are manual and very labor intensive.
Предложенный способ позвол ет сократить трудоемкость процесса изолировани , уменьщить стоимость издели и придать изолирующему слою наиболее рациональную конфигурацию.The proposed method makes it possible to reduce the laboriousness of the isolation process, reduce the cost of the product and give the insulating layer the most rational configuration.
Это достигаетс тем, что в качестве электроизол ционного материала применен гипс, образующий монолитный слой изол ции.This is achieved by using gypsum as an electrically insulating material, which forms a monolithic insulation layer.
На чертеже схематически показана литейна форма дл изолировани обмоток указанным способом.The drawing schematically shows a mold for insulating windings in this way.
Здесь: 1-литник, 2-стержень, 3-выпор, 4-разъемна форма, 5- выводы обмотки, 6-обмотка.Here: 1-sprue, 2-rod, 3-flange, 4-split form, 5- winding leads, 6-winding.
Секцию обмотки помещают в разъемную форму, заливают гипсовым раствором, который, затвердева , создает вокруг секции плотную монолитную оболочку. После затвердевани гипса изолированную секцию обмотки извлекают из формы и сущат.The section of the winding is placed in a detachable form, filled with plaster mortar, which, solidified, creates a dense monolithic shell around the section. After the plaster has hardened, the insulated section of the winding is removed from the mold and existing.
Сущку производ т при 100-120°. После окончательной сборки ап парата секцию погружают в масло и вторично сущат в вакууме при 100°. В процессе первой сущки из секции удал етс влага, при второй - воздух .Drying is done at 100-120 °. After the final assembly of the aparath, the section is immersed in oil and re-formed in vacuum at 100 °. During the first process, moisture is removed from the section, and air is removed from the second.
