Abstract
737,522. Transformers. VANIER, G. July 18, 1953, No. 19968/53. Class 38 (2). [Also in Group XXXVII] The secondary winding 34 of a transformer is provided with tappings 31, 32, 33 which are connected to the contacts 11, 13, 15 of an onload tap changing switch having an arm 7 fixed to a rotatable shaft. Auxiliary contacts 12, 14 are arranged between the main contacts and the arm 7 is of such width that it makes contact during its movement with each pair of adjacent contacts. To limit the current flowing in the short-circuited portions of the transformer winding when the arm 7 engages the pairs of contacts 11, 12 and 14, 15 the contacts 12, 14 are connected to the tapping 32 through a resistance 37. Arcing contacts 35 ... 41 are provided between the main and auxiliary contacts. The shaft of the arm 7 may be rotated by a Maltese Cross which can be rotated in either direction by a motor, the cross and motor being connected through intermediate mechanism in which a spring provides a quick action to the cross when the arm 7 is to be moved. When the spring is in action the current to the motor is automatically cut off.
