Single Phase To Split Phase Transformer

When single-phase AC is applied to the primary winding, it generates a pulsating alternating magnetic field in the transformer core.

This pulsating magnetic field simultaneously cuts the two windings on the secondary side (usually arranged at 90 degrees in space).

Since the two secondary windings are orthogonal in space (90 degrees), according to the law of electromagnetic induction (Faraday's law), their induced electromotive force (voltage) will naturally produce a 90-degree phase difference in time.

The output voltage amplitude can be ensured to be equal through precise winding turns ratio and connection method.

Before overload operation, check whether the transformer has serious defects (such as abnormal cooling system, serious oil leakage, partial overheating, abnormal analysis results of dissolved gas in oil, etc.) or insulation weakness. If so, it should not be overrun. Load operation. When the transformer is running under overload, the spare cooler should be put into operation immediately, and the temperature of the upper layer of the transformer, ambient temperature and time should be observed. And record the overload time and overload multiple, the overload multiple during normal overload operation.

Powering two-phase devices: This is the main purpose. In the early days of electricity, especially in the United States, there were some motors (induction motors, synchronous motors) and other devices that used a two-phase (four-wire) system. Single-phase to split-phase transformers can convert the then-popular single-phase mains electricity into the two-phase power required by these devices.

Generate a rotating magnetic field: Two-phase electricity with a 90-degree phase difference, when input to a two-phase motor (usually with two stator windings that are 90 degrees apart in space), can generate a rotating magnetic field. This rotating magnetic field is the key to driving the rotor to rotate. This is its most important electrical characteristic.

Baoding Yuanchen Transformer (established in 1999) has more than 20 years of experience and a factory area of ​​98,000 square meters. With complete technical strength, its products cover 6 categories and nearly 100 specifications, with an annual output of 5 million KVA. In October 2020, it passed the three-system certification of quality, environment, and occupational health and safety. It was awarded the title of high-tech enterprise, 2022 specialty and new and national energy-saving technology recommendation.
