Description
Предметом изобретени вл етс соединительна муфта дл одножильного кабел высокого напр жени .The subject of the invention is a coupler for single-core high-voltage cable.
Известные высоковольтные муфты с;южны в изготовлении и неудобны при монтаже.Known high-voltage couplings from; southern to manufacture and inconvenient during installation.
Предлагаема муфта отличаетс от известных простотой конструкции, небольшими габаритами и высоким пробивным напр жением. Кроме того , монтаж мус|)ты прн установке ее в кабельных лини х менее сложен, чем установка муфт известных конструкций .The offered coupling is distinguished from the ones known for its simplicity of construction, small dimensions and high breakdown voltage. In addition, the installation of a mus |) you install it in cable lines is less complicated than the installation of couplings of known designs.
Па чертеже изображен продольный разрез муфты.Pa drawing shows a longitudinal section of the coupling.
Стальной корпус / муфты состоит из двух частей, герметически закрывающих место соединени кабел . Муфта снабжена двум выходными отверсти ми-верхним 2 и нижним 3.The steel casing / coupling consists of two parts, hermetically closing the junction of the cable. The clutch is equipped with two outlets mi-upper 2 and lower 3.
При заполнении муфты кабельной массой 4 под вакуумом через верхнее отверстие нижнее отверстие открываетс и через него выпускаютс первые порции кабельной массы, что способствует уменьшению пустот, не заполненных кабельной массой, аWhen the coupling is filled with cable mass 4 under vacuum, the lower hole opens through the upper opening and through it the first portions of the cable mass are released, which helps to reduce voids not filled with cable mass, but
также удалению влаги из внутренней полости муфты.also remove moisture from the inner cavity of the coupling.
Дл обеспечени плавного изменени электрического пол предусматриваетс стзпенчата разделка 5 заводской изол ции, кабел , имеюща .минимальную высоту каждой ступени (0,16-0,20 мм}.To ensure a smooth change in the electric field, it is necessary to use a clamping stripping 5 of factory insulation, a cable having a minimum height of each step (0.16-0.20 mm}).
Подмотка кабел 6 производитс изол ционной бумагой, при этом до диаметра 33 мм примен етс бумажна лента шириной 10 мм. от диаметра 33 до 40 мм - лента шириной 15 мм и от диаметра 40 до 60 мм - лента шириной 100 и 200 мм. TaKoii способ обмоткн делает равнопрочной в отношении пробо как в радиальном, так и в тангенциальном иаправленин.The coil of cable 6 is produced by insulating paper, with a 10 mm wide paper tape being used up to a diameter of 33 mm. from diameter 33 to 40 mm - a tape 15 mm wide and from a diameter of 40 to 60 mm - a tape 100 and 200 mm wide. TaKoii winding method makes equal strength with respect to breakdown in both radial and tangential direction.
Наружный цилиидрический слой подмотки экранируетс перфорированной металлизированной бумаго 7, а на конусных част х - медной или свинцовой проволокой 8. Дл устранени складок и продольных каналов на конусных част х подмотки нат жение бумажной ленты уменьшаетс по мере з величени диаметра подмотки.The outer cylindrical underwinding layer is shielded with perforated metallized paper 7, and on the tapered parts with copper or lead wire 8. To eliminate folds and longitudinal channels on the tapered parts of the winding, the tension on the paper tape decreases as the winding diameter increases.
Наружна поверхность муфты защищена слоем 9, состо щим из мен кови1 ы, пропитанной битумом.The outer surface of the coupling is protected by a layer 9 consisting of a menstrual impregnated with bitumen.
