400v D11 MR 160KVA Single Phase Power Transformer

A single-phase transformer is a transformer in which both the primary winding and the secondary winding are single-phase windings. Unipolar switching power supply means that the output is unipolar, that is, only positive and negative output. Compared with bipolar switching power supply, the bipolar switching power supply has three outputs, which are divided into the positive power supply, negative power supply, and ground wire. . Single-phase transformers are simple in structure, small in size, and low in loss, mainly due to small iron loss. They are suitable for application and promotion in low-voltage distribution networks with low load density. Suzhou City has used more than 1,000 units in total, saving 45GWh of electricity, and the experience is worth promoting. Some data show that single-phase transformers are widely used in developed countries, such as the United States and Japan. A Single-phase power supply is the main way to supply power to residents. Under this propaganda, some people think that a single-phase power supply has "loss reduction". The magic is that single-phase transformers are more energy-efficient than three-phase transformers and single-phase power supply systems are superior to three-phase power supply systems. In fact, the single-phase transformer and single-phase power supply system are only supplementary forms of the current three-phase power supply system. Due to its own characteristics, it can only be applied to certain specific fields. "
