Claims (6)

1. Visokonaponska strujna navojnica, koja sadrži cilindričnu jezgru (6), koja je postavljena u metalnom kućištu (8) navojnice zajedno sa sekundarnim navojima (7), čiji krajevi su postavljeni u spojnu navojnicu (12) i u jednu metalnu cijev (10), što preko navojnice nije trajno spojena sa nastavnom spojnom navojnicom, pri čemu metalna cijev (10) predstavlja strujni provodnik za transformator (1), a provodnik se nalazi zajedno sa metalnim kućištem (8) u izolirajućem materijalu, naznačen time, da je metalna cijev (10), koja tvori element provodnika transformatora, opremljena s metalnim zaštitnim zvonom u obliku čunjastog završetka, čija baza je usmjerena s većim promjerom u smjeru spojne navojnice (12), krajevi baze čunja s manjim promjerom su čvrsto povezani s vanjskom površinom metalne cijevi (10), a pri tom su rubovi baze čunja savijeni s većim promjerom u unutrašnjost čunja.1. High-voltage current coil, which contains a cylindrical core (6), which is placed in the metal casing (8) of the coil together with secondary threads (7), the ends of which are placed in the connecting coil (12) and in one metal tube (10), which is not permanently connected to the teaching connecting coil through the coil, whereby the metal pipe (10) represents the current conductor for the transformer (1), and the conductor is located together with the metal casing (8) in the insulating material, indicated by the fact that the metal pipe ( 10), which forms an element of the transformer conductor, equipped with a metal protective bell in the form of a conical termination, the base of which is directed with a larger diameter in the direction of the connecting coil (12), the ends of the base of the cone with a smaller diameter are firmly connected to the outer surface of the metal pipe (10 ), while the edges of the base of the cone are bent with a larger diameter into the interior of the cone. 2. Navojnica prema zahtjevu 1, naznačena time, da je zaštitno zvono (14) postavljeno u navedenom izolacijskom materijalu (16a).2. Thread according to claim 1, characterized in that the protective bell (14) is placed in said insulating material (16a). 3. Navojnica, prema zahtjevu 1, naznačena time, da zaštitno zvono (14) ima jedan poprečno postavljen prolaz (14a).3. Thread, according to claim 1, characterized in that the protective bell (14) has one transversely positioned passage (14a). 4. Navojnica prema zahtjevu 1, naznačena time, da su u zaštitnom zvonu (14) rubovi baze čunja na jednom mjestu povezani manjim promjerom s vanjskom površinom metalne cijevi (10), koje leži ispod vanjskog navoja (11) cijevi (10).4. Thread according to claim 1, characterized by the fact that in the protective bell (14) the edges of the base of the cone are connected in one place with a smaller diameter to the outer surface of the metal tube (10), which lies below the outer thread (11) of the tube (10). 5. Navojnica prema zahtjevu 3, naznačena time, da su u zaštitnom zvonu (14) rubovi baze čunja preko jednog varenog šava (15) povezani manjim promjerom s vanjskom površinom metalne cijevi (10).5. Thread according to claim 3, characterized by the fact that in the protective bell (14) the edges of the base of the cone are connected by a welded seam (15) with a smaller diameter to the outer surface of the metal tube (10). 6. Jedan kombinirani transformator, koji sadrži jedan transformator napona (2) i jedan izolator 83), kao i transformator struje (1), naznačen time, da sadrži visokonaponsku strujnu navojnicu prema zahtjevima 1 do 4.6. One combined transformer, which contains one voltage transformer (2) and one insulator 83), as well as a current transformer (1), characterized in that it contains a high-voltage current coil according to claims 1 to 4.
