    The invention relates to electrical engineering, in particular to combined current and voltage transformers. The purpose of the invention is to simplify manufacture and increase reliability. The transformer contains a high-voltage current transformer 1 and a voltage transformer placed in its housing in the upper part, the transformer is hermetically attached to the closing plate 8, which is supported on the insulating column 2. The current transformer 1 contains a primary conductor U-shaped with a base 19 and two 20 and 21. Base 19 passes through a ring 15 of insulating material with cores having secondary winding sections. A voltage transformer located in the housing head is mounted on the top of the ring 15 through the plug device 54. The terminals of the primary winding of a current transformer pass through a closing plate made of metal, on which a casing is installed, to form a hermetic structure. One of the terminals of the primary winding passing through the closing plate is electrically isolated. The features of the implementation of some elements of the combined transformer and their mounting on the housing and with each other are described. 15 hp f-ly, 7 ill.
