Description
7908551-0 ï g - 2 Uppfinningen heskrives närmare med hänvisning till bifogade ritning, som visar ett utföringsexempel av den nya lastväljaren i längdsektion. . 7 Såsom av figuren framgår består den nya lastväljaren väsentligen av ett cylindriskt hölje 1, vilket uppbär de fasta kontakterna 2, av ett drivanordningen innehållande lindningskopplarhuvud 3 och av ett centralt i höljet 1 anordnat isolerrör 4, som är vridbart i steg och uppbär de rörliga kontakterna 5. Höljet 1 har en botten 6 med uppvikta flänsar, vilken botten i mitten har en-ihålig tapp 7; På denna ihåliga gtapp 7 är isolerröret 4 påsatt. Detta sker över en lagerring 8, som uppbäres av isolerrörets undre ände. Genom lagerringen 8 är från lind- ningskopplarhnvudet 3 en centrerstång 9 instucken i den ihåliga tappen 7, så att isolerröret 4 med sin undre lagerring 8 är exakt centrerat. Även vid centrerstângens 9 övre ände 10 är en lagerring 11 inrättad. Denna lagerring för med sig den med isolerröret 4 över ett mellanstycke 12 förbundna malteserskivan 13. I övrigt är centrerstången fastskrnvad i lindningskopplarhuvudets 3 lock 14. 0 Den beskrivna centrerstången 9 är utformad såsom oljeutsugnings- ledning. För detta ändamål är först ett oljegenomsläppande borrhål 15 inrättat i den ihåliga tappen 7 alldeles vid bottnen 6. Vidare finns i den koniska spetsen 16 på den ihåliga centrerstången 9 ytterligare olje- genomsläppande borrhâl 17, och slutligen uppbär den ihåliga centrerstâng- ens i locket 14 fastskruvade ände 10 en anslutningsfläns 18 för anslut- ning av en yttre oljeledníng. Centrerstången är utformad i tre delar, .varvid den undre genom lagerringen 8 invi den ihåliga tappen 7 inskjutan- I de spetsen 16 består av metall, den mittre delen 19 av isolerämne och den övre i lindningskopplarhuvudets 3 lock 14 fastskruvade delen 10 åter består av metall. Den övre delen 10 och den mittre delen 19 är in- stuokna i varandra och försedda med en.glidtätning, så att en längd- eller toleransutjämning kan äga rum över denna. 7908551-0 ï g - 2 The invention is described in more detail with reference to the accompanying drawing, which shows an embodiment of the new load selector in longitudinal section. . 7 As can be seen from the figure, the new load selector essentially consists of a cylindrical housing 1, which carries the fixed contacts 2, of a drive device containing winding coupler head 3 and of a insulating tube 4 arranged centrally in the housing 1, which is rotatable in steps and carries the movable contacts 5. The housing 1 has a bottom 6 with folded up flanges, the bottom of the center having a hollow pin 7; On this hollow tap 7, the insulating tube 4 is attached. This is done over a bearing ring 8, which supported by the lower end of the insulating tube. Through the bearing ring 8 is from the winding the coupling head 3 a center rod 9 inserted into the hollow pin 7, so that the insulating tube 4 with its lower bearing ring 8 is precisely centered. Also at the upper end 10 of the center rod 9 a bearing ring 11 is arranged. This bearing ring carries it with the insulating tube 4 over an intermediate piece 12 connected Maltese disc 13. Otherwise, the center bar is screwed into winding coupler head 3 cover 14. The described center rod 9 is designed as an oil extraction management. For this purpose, first an oil-permeable borehole 15 set up in the hollow pin 7 right at the bottom 6. Furthermore, in the conical tip 16 of the hollow center rod 9 further oil through borehole 17, and finally supports the hollow center rod even in the cover 14 screwed end 10 a connecting flange 18 for connecting of an external oil line. The center bar is designed in three parts, wherein the lower through the bearing ring 8 is inserted into the hollow pin 7. In the tip 16 consists of metal, the middle part 19 of insulating material and the upper part 10 screwed into the cover 14 of the winding coupler head 3 again consists of metal. The upper part 10 and the middle part 19 are included. stitched together and provided with a non-slip seal, so that a longitudinal or tolerance equalization can take place over this.
