How to use naked three phase lsolation transformer safely

1. The naked three phase lsolation transformer has one and secondary coils, which energize the secondary side through the magnetic circuit, instead of directly generating electrical connection with the central point grounding system on the primary power side, so it has a good electrical function of blocking the ground.

2. When the electrical equipment enclosure leaks, no matter which end of the secondary coil is connected to the electrical enclosure, it will not cause a personal electric shock. This kind of transformer is equipped with fuses in the primary and secondary stages, and the iron core and metal shell of the transformer are firmly connected to the ground, which has a shielding effect and has anti-interference function. It is used as a safe power supply for instruments and electric manual tools. reliable.

3. The voltage of the naked three phase lsolation transformer can be selected according to the needs, and the specifications of a single-phase 220/220V, 220/36V. 380/220V are available. Three-phase 380/380V, 380/220V, 380/36V. In use, pay special attention to the total capacity of the electrical appliances to be smaller than the capacity of the safety barrier transformer. The capacity of safety barrier transformers now produced is 0.1-15KVA. When connecting three-eye safety sockets in rural households, the grounding terminal of the electrical socket should be connected to the zero wire of the three-phase four-wire system to achieve the purpose of maintaining the zero connection. It can be used for the maintenance of household appliances, such as washing machines, refrigerators, etc. Because these household appliances work in a humid environment, their metal shells are prone to leakage. But to use this method, you need to connect the ground terminal of the socket directly to the zero line before entering the house.
