INSTALLATION FOR STUDYING THE TRANSITORY DUTIES OF TRANSFORMERS

摘要

The invention relates to an installation for studying the transitory duty of a transformer (TE) upon empty running. The installation comprises a device regulating the connecting phase of the transformer (TE) which consists of a synchronous micrometer (1) on whose axle there is mounted a first disc (2) provided radially with a permanent magnet (3) rotating together with the disc (2) at a synchronous speed of 3000 rpm. A second disc (4) is positioned coaxially in front of the first disc (2), said second disc being provided radially with a magnetically actuated contact (5) which controls the test transformer power supply and makes possible the regulation of the connecting phase by changing the position of this disc (4) as against a reference position (7).
