Scott transformer is usually composed of two single-phase transformers. Connecting the end of one transformer high-voltage winding to the center of another high-voltage winding can form a three-phase high-voltage winding with "t" junction. Each low-voltage winding is a simple single-phase winding, and there is no electrical connection between them. Their voltage and current are the same as those of ordinary single-phase transformers. However, each high-voltage winding and current are different from ordinary single-phase transformers. Scott transformer is a three-phase 380V to two-phase 220V transformer. The output secondary is connected to two loads with the same power, which can achieve the effect of three-phase balance. It can be applied to equipment with large single load, and the voltage can be customized according to user requirements.

Application

It is applicable to the circuit with only one single-phase or two-phase load. Because the mains power is a three-phase four wire power supply and the output is a single-phase or two-phase load, the current of the three-phase power supply of the mains power is unbalanced and the phase bias load is serious; Our company's technical engineers for many years have developed and repeatedly tested this series of transformers; It can solve the loss and low utilization caused by serious imbalance of three-phase power supply of power grid caused by single-phase or two-phase load equipment of users. It is applied to the power supply of locomotive traction, heating equipment, smelting and other circuits (three-phase to single-phase / two-phase). The company can carefully design and customize various high and low voltage non-standard special transformers according to the needs of users.

3. Output voltage: rated working voltage and no-load voltage

4. Output current: output rated working current or no-load current

5. Overall dimension: length, width and height of transformer

6. Special requirements: other special shall refer to temperature rise, efficiency, insulation grade, voltage regulation rate, wiring mode, etc.

7. Scenario usage: when designing special transformers, technical engineers need to understand the industry and working scenario in which the transformers are used, so as to design transformers that meet the user's needs
