Abstract
1495656 Transformer tap changing equipment MASCHINENFABRIK REINHAUSEN Gebr SCHEUBACK KG 27 Oct 1975 [9 Nov 1974] 44130/75 Heading H1T Transformer tap changing equipment comprising tap changing switch arrangement 3 in a vessel containing oil, is provided with a separate expansion chamber 8 disposed immediately above the main chamber, the two being separated by a wall 7 which has an aperture 9 through which oil or gas may flow. The aperture 9 is covered by a plate 11 on which is pivotally mounted a relay contact whereby flow of oil or gas through a hole 12 in the plate causes the relay to operate. Instead of the arrangement shown which has an integral welded wall 7, the arrangement may comprise a separate expansion tank overlying the top wall of the main tank, the aperture 7 being provided by aligned holes in the adjacent walls.
