<p>PURPOSE:To facilitate transfer connection from a faulty transformer to a stand-by transformer by providing a transfer terminal conductor detachably between a cable connecting three single-phase transformers of three-phase connection and a bushing terminal for each transformer. CONSTITUTION:Single-phase transformers 1-3 constitute a three-phase bank, and a single-phase transformer 4 is provided as stand-by transformer. The transformers 1-4 have a bushing terminal 5 and are enclosed in a connection duct 6 together with heads 7a, 7b, 8a of cables 7, 8 connecting transformers 1-4. Then, the bushing terminal 5 for the transformers 1-4 and the cable heads 7a, 7b, 8a are formed detachably with a transfer terminal conductor 9. Where one transformer gets faulty, it can be easily transferred to a stand-by transformer simply by changing a connection between the bushing terminal 5 and the cable heads 7a, 7b, 8a with the transfer terminal conductor 9.</p> |
