check the normal periodic load operation of high frequency transformer

- Jul 12, 2018-

                                   Normal periodic load operation:
1. Under rated service conditions, the high frequency transformer can operate at rated current all year round.
2. The transformer is allowed to run over the fixed current periodically when the average relative aging rate is less than or equal to 1.
3, when the transformer has the serious defects, such as the cooling system is not normal, serious leakage, have local overheating, abnormal results, analysis of gases dissolved in transformer oil, etc.) or insulation have weaknesses, unfavorable excess constant current operation.

4. Under normal periodic load operation mode, the allowable load coefficient K2 and time can be determined according to one of the methods of load guide when the overspecified current is running.

The difference between no-load and load of high frequency transformer

The main difference between the no-load operation and the load operation of the transformer is mainly reflected in the secondary line country. Generate micro power

Transformers use the principle of electromagnetic induction to change the ac voltage device, the main components are primary coil, secondary coil and iron core (magnetic core). It is often used in electrical equipment and wireless circuit as lifting voltage, matching impedance, safety isolation, etc. When the transformer is running at no load; It only consumes no-load loss, i.e., iron loss and stray loss, which is 6% of the total capacity. During load operation, it is no-load loss + load loss, i.e., copper loss, which is the total consumption of the transformer.
