Abstract
Inventia se refera la o bobina primara pentru transformatoare de curent de înalta tensiune care are o înfasurare formata din n spire egale si transpuse cu 360 degree /n obtinute dintr-o singura teava de cupru montata pe un tub izolant si îmbracata de doua semituburi si consolidata cu o banda electroizolanta si izolata exterior cu carton electroizolant si la un procedeu de realizare a acestei bobine care consta din decuparea unei tevi prin frezari pe generatoare si obtinute în spire carora li se aplica la capete prin sudura, niste piese de conexiune filetate, montarea spirelor pe un tub izolant, introducerea între spire a unei acoperiri pe exterior cu semituburi izolante, înfasurarea cu banda de consolidare si izolarea finala cu carton electroizolant.The invention relates to a primary coil for high-voltage current transformers having a twist of equal turns and transposed with 360 degrees / n obtained from a single copper pipe mounted on an insulating tube and embedded in two semitubes and reinforced with an electrically insulating and insulated outer strip with insulating board and a process for making this coil consisting of cutting a pipe through milling on generators and obtained in coils which are applied to the ends by welding, some threaded connection pieces, the mounting of the spirals on an insulating tube, the insertion between the spirals of an outer covering with insulating seams, the consolidation tape and the final insulating with insulating board.
