適用范圍：This International Standard deals with safety aspects of power transformers, powersupplies, reactors and similar products such as electrical, thermal and mechanical safety.This standard covers the following types of dry-type transformers, power supplies,including switch mode power supplies, and reactors, the windings of which may beencapsulated or non-encapsulated :NOTE 1 The distinction between transformers, power supplies and switch mode power supplies is as follows:– for transformers, there is no change in frequency .However, transformers (e.g. constant voltagetransformers) may have an internal resonance frequency not exceeding 30 kHz;– for power supplies, the internal operational frequency and waveform are different from the supplyfrequency and waveform, and the internal operational frequency does not exceed 500 Hz (see definition3.1.19);– for switch mode power supplies, the internal operational frequency and waveform are different from thesupply frequency and waveform and the internal operational frequency exceeds 500 Hz and does notexceed 100 MHz.
