Voltage transformer for high voltage

Abstract

A voltage transformer for use with high voltages. The transformer includes an insulating body in which is disposed a high-potential winding and a bushing laterally joined to the insulating body. In accord with the invention, the transformer is further provided with control electrodes in the form of conducting cylinders which are disposed concentrically with respect to the longitudinal axis of the bushing, thereby affording control of the bushing at both its ends. Moreover, in further accord with the invention, the high-potential winding is arranged adjacent to one side of the bushing so that its width extends over the control length thereof, and is comprised of subwindings which are metallically connected to the respective conducting cylinders such that a uniform voltage distribution results during the occurrence of surge voltages.
