Abstract

1282782 Transformers SMIT NIJMEGAN ELECTROTECHNISCHE FABRIEKEN NV 1 Oct 1969 [2 Oct 1968] 48319/69 Heading HIT A tap selector has for each phase fixed contacts 27-34 arranged in a circle through which connection is effected as required to tappings 3-10 of a regulating winding by at least two movable contacts 35 and 36 one of which, 36, is connected to a member 24 for connection to a line or neutral connection 25 and the other or others 35, 37 are connected to 24 through a transitional impedance 38, 39, at least the fixed contact 34 connected to the highest voltage tapping being of greater angular extent than the other fixed contacts. If there are three moving contacts the fixed contact 27 is also of greater angular extent than the contacts 28-33. If only two moving contacts (68, 69, Fig. 4, not shown) are provided only the fixed contact (78) connected to the highest tapping is larger than the others. An arrangement, also described has a winding having coarse tapping steps and a changeover selector switch. In this arrangement the tap selector as provided with an extra fixed contact (51, Fig. 3, not shown) which is disposed between the fixed contacts (44, 50) connected to the highest and lowest of the fine tappings 3-10 and is also of greater angular extent than the contacts connected to tappings 5-9.
