Design for converting 440V to 380V
Thread Content
I have a power distribution cabinet operating at 440V 60HZ. The loads include a device that requires 380V 50HZ and 5KW of power, as well as another device that requires 220V and 0.8KW of power. How should I design it? What are the appropriate capacities and specifications for the transformer, fuses, and switches?
There’s no need to replace it; this distribution cabinet can still be used!
I agree with the opinion above, but it is necessary to consider whether the capacity of the original components inside the cabinet is sufficient to power the equipment.
The distribution cabinet operates at 440V, 60HZ; the frequency is indeed 60HZ. Is it imported from abroad, or did you make a mistake? The frequency of China’s power grid is 50HZ. Are you referring to the parameters of the distribution cabinet or those of the power supply in the grid?
The circuit breaker meets the load requirements; it is indeed for the foreign frequency. Everyone, please continue
