Power Transformers

Power Transformers

A.  Overview
A transformer commonly used to provide suitable power source to various equipment or products.

B.  Features
The toroidal transformer used in the power transformer has the characteristics of large random size, single structure, high magnetic performance utilization, relatively low temperature rise and relatively high working efficiency, and has good cost performance.

C.  Design Considerations
1.  High work efficiency
2.  Low operating loss
3.  Thermal Protection
4.  Low vibration and noise
5.  International Power Transformer Safety Standard
6.  Power 10VA~10KVA

D.  Temperature resistance level and product temperature rise
Typically we design that over ambient of 25°C, product temperature rise is as follows:
1.  Class A: 105°C, Temperature rise below 60°C
2.  Class B 130°C, Temperature rise below 75°C
3.  Class F 155°C, Temperature rise below 95°C
4.  Class H 180°C, Temperature rise below 125°C
5.  Or suitable temperature grade and suitable temperature rise

E.  Compliance Standard
IEC61558

F.  Design required parameters
1.  Input voltage (V)
2.  Working frequency (Hz)
3.  Output voltage (V)
4.  Output current (A) or output power (W)
5.  Transformer installation space
6.  Transformer installation and connection method
7.  Requirements of temperature resistance level, efficiency, power consumption

  • High Frequency Power Supply Transformer

    High Frequency Power Supply Transformer

    Tranformer Process: 1.The iron core is tightly wound, annealed at high temperature, fixed and moisture-proof by dipping insulating oil, chamfering process at the edge, protected by insulating tape with good tensile property at high temperature 2.Insulation: we will use insulating materials which is with high temperature resistance and good insulation performance. And it has sufficient overlapping width and number of insulating layers. 3.Copper wire: we will use double-insulation lacquered copper wire, standard winding process, using relatively low winding speed and tension to better enhance transformer quality. 4.Wiring soldering tin head, insulated and isolated by fiber tube which is with high temperature resistance and good insulation performance 5.Transformer finished product aging 6.Transformer 100% full inspection
