Definitions

  • the invention relates to a cylindrical diverter switch according to the preamble of claim 1.
  • DE 763 245 already describes a tap changer in which the actuating gear is arranged between the tap selector and the turner and the diverter switch located above it.
  • the drive transmission gearbox which in turn is arranged between the diverter switch and the tap selector, is connected to the tap changer head via a drive shaft located outside the oil tank of the diverter switch.
  • the position of the diverter switch insert in the oil cylinder is fixed in the vertical direction by a yoke, which is also screwed into the tap changer head.
  • the object of the invention is to find a simplification here on the one hand and to allow quick and uncomplicated dismantling of the diverter switch insert and on the other hand to make tolerance compensation between the oil tank and the diverter switch insert possible in a simple manner.
  • a hollow support column 9 made of insulating material runs vertically, which is provided in the upper area with bores 10, 11, which are each arranged opposite one another in two horizontal planes.
  • the spring bars 12, 13 advantageously have a round cross section, and the bayonet-like recess 14 is U-shaped or V-shaped.
  • the upper end face of the support column 9 is flat and at a short distance parallel to the inner surface of the cover 16 of the tap changer head. This provides an additional safeguard against the fact that violent impacts from below, for example during transport or when accidentally falling over, could cause the diverter switch insert 2 against the force of the spring rods 12, 13 to release upward from the locking device on the bottom of the oil container 1.
  • FIGS 3 to 6 show examples of different possibilities of the bayonet-type fasteners.
  • Fig. 3 the recess already described is shown in the form of a U-shaped milling in the wall of the oil vessel 1. Although this milling requires a certain amount of production effort, it narrows the usable inner diameter of the oil container, particularly when assembling and disassembling the diverter switch insert 2, not one, so that a space-saving design is possible.
