 von   Kühlkanälen   in den Kernen gewählt wird. 



   Die zur Befestigung dienenden Bolzen 5 können so bemessen und angeordnet werden, dass sie auch für den Transport des Transformators benutzbar sind. Wählt man als Teile des magnetischen Kreises solche von besonders grosser Steifheit, sind keine sich über das ganze Joch erstreckende Endplatten nötig, aber es genügt, in der Verlängerung der Kernachse Abschlussplatten 7 anzuordnen, deren Durchmesser ungefähr dem Kerndurchmesser entspricht, wobei Isolierscheiben 8 dazwischen gelegt sind. Zentrierstück 9 zwischen Kern und Bolzen in der Nähe der Trennfugen 6, 6' verhindern die Verschiebung der Kerne. 



   Die Dreiphasen-Transformatoren gemäss vorliegender Erfindung sind dank ihrer einfachen, kräftigen Bauelemente ausserordentlich einfach zu montieren und zu demontieren, was im übrigen mit grossen Vorteilen bei ihrem Transport verbunden ist.

 of cooling channels in the cores.



   The bolts 5 used for fastening can be dimensioned and arranged such that they can also be used for transporting the transformer. If parts of the magnetic circuit are chosen that are particularly rigid, no end plates extending over the entire yoke are necessary, but it is sufficient to arrange end plates 7 in the extension of the core axis, the diameter of which corresponds approximately to the core diameter, with insulating washers 8 placed in between . Centering piece 9 between the core and bolt in the vicinity of the parting lines 6, 6 'prevent the cores from shifting.



   The three-phase transformers according to the present invention are extremely easy to assemble and dismantle thanks to their simple, strong components, which is also associated with great advantages in their transport.
