変圧器。[Scope of Claim for Utility Model Registration] In a three-phase transformer that supplies three single-phase transformers with three-phase AC power, a two-phase AC power supply side feeder line for supplying power to each single-phase transformer. A bypass circuit is formed between the AC power supply side feed line of one phase and the load side feed line of the corresponding phase, and one end is connected to the load side feed line. (or the AC power supply side feed line), and connect the other end of this power transmission line and the single-phase transformer to the AC power supply side feed line (or load side feed line) of one of the phases. a switching means that can be connected alternatively; a first disconnection means that can disconnect each of the single-phase transformers from the load-side power supply line (or AC power supply side power supply line) of one of the phases; and each of the single-phase transformers described above; A second disconnection means capable of disconnecting the single-phase transformer from the other of the two-phase AC power supply side feed line for feeding the transformer and the load side feed line of the corresponding phase is provided. Characteristic three-phase transformer.
