適用范圍：Replacement:This part of IEC 61558 deals with the safety of auto transformers for general applicationsand power supply units incorporating auto transformers for general applications.Transformers incorporating electronic circuits are also covered by this standard.NOTE 1 Safety includes electrical, thermal and mechanical aspects.Unless otherwise specified, from here onward, the term transformer covers autotransformers for general applications and power supply units incorporating autotransformers for general applications.NOTE 2 : For power supply units (linear) this part is applicable. For switch mode power supply units, IEC 61558-2-16 isapplicable together with this part.This part is applicable to stationary or portable, single-phase or polyphase, air-cooled(natural or forced) independent or associated dry- type transformers. The windings may beencapsulated or non-encapsulated.The rated supply voltage does not exceed 1 100 V a.c., and the rated supply frequencyand the internal operating frequencies do not exceed 500 Hz.The core power does not exceed:– 2 kVA for single-phase transformers;– 10 kVA for polyphase transformers.The rated output does not exceed:– 40 kVA for single-phase transformers;– 200 kVA for polyphase transformers.This part is applicable to transformers without limitation of the core power and the ratedoutput both being subject to an agreement between the purchaser and the manufacturer.Where applicable, the no-load output voltage or the rated output voltage does not exceed1 000 V a.c. or 1 415 V ripple-free d.c., and for independent transformers, the no-loadoutput voltage and the rated output voltage exceeds 50 V a.c., or 120 V ripple-free d.c.This part is not applicable to external circuits and their components intended to be connectedto the input terminals and output terminals of the transformers.Transformers covered by this part are used only in applications where no insulationbetween circuits is required by the installation rules or by the end product standard.NOTE 3 Attention is drawn to the following:– for transformers intended to be used in vehicles, on board ships, and aircraft, additional requirements (fromother applicable standards, national rules, etc.) may be necessary;– measures to protect the enclosure and the components inside the enclosure against external influences suchas fungus, vermin, termites, solar-radiation, and icing should also be considered;– the different conditions for transportation, storage, and operation of the transformers should also beconsidered;– additional requirements in accordance with other appropriate standards and national rules may be applicable totransformers intended for use in special environments.NOTE 4 Future technological development of transformers may necessitate a need to increase the upper limit ofthe frequencies, until then this part may be used as a guidance document.
