Abstract
433,153. Transformers. ELECTRIC CONSTRUCTION CO., Ltd., Ingersoll House, Kingsway, London, and GLEDHILL, E., Bushbury Engineering Works, Wolverhampton. Feb. 13, 1934, No. 4716. [Class 38 (ii)] In a transformer in which one of the windings D is divided with tappings on either side of the break connected to contacts 1-6 arranged in a circle and adapted to be bridged in pairs by a movable contact plate b there is further provided leading and trailing plates c, a which are connected to the main plate b through the two halves AT<2>, AT of an auto-transformer T. This arrangement enables on-load tapchanging to be effected and voltages intermediate the taps to be obtained. When the plates are in the position shown the tappings 1, 2 are connected together. When the switch is rotated so that the contact 2 is in the centre of plate b and contacts 1 and 3 engage with plates a and c respectively the tap 2 is connected to tappings 1 and 3 through the autotransformer T and a voltage intermediate these tappings is obtained. To reduce the impedence of the autotransformer in this position it may be provided with secondary windings which are short-circuited by a switch in this position. In addition these windings may be permanently bridged by a resistance inductance or condenser. Alternatively, instead of being bridged by a switch in this position they may be bridged by an impedence.
