适用范围：This part of IEC 61558 deals with the safety of shaver transformers, power supply unitsincorporating a shaver transformer, and shaver supply units. Shaver transformersincorporating electronic circuits are also covered by this standard.NOTE 1 Safety includes electrical, thermal, mechanical and chemical aspects.Unless otherwise specified, from here onward, the term transformer covers shavertransformers and power supply units incorporating shaver transformers and shaversupply units.This part is applicable to stationary, single phase air-cooled (natural or forced), independentor associated dry- type transformers. The windings may be encapsulated or nonencapsulated.This standard is applicable to transformers and power supply (linear) with internaloperational frequencies not exceeding 500 Hz.This standard used in combination with Part 2-16 for switch mode power supply units(SMPS) is also applicable to power supplies with internal operational frequencies higher than500 Hz. Where the two requirements are in conflict the most severe take precedence.The rated supply voltage does not exceed 250 V a.c., and the rated supply frequency doesnot exceed 500 Hz.The rated output is not less than 20 VA and does not exceed 50 VA .The no-load output voltage does not exceed 275 V a.c and the rated output voltage doesnot exceed 250 V a.c.This part is not applicable to external circuits and their components intended to be connectedto the input and output terminals or socket-outlets of the transformers.Transformers covered by this part are used in applications where double or reinforcedinsulation between circuits is required by the installation rules for bathrooms and similarlocations, or by the appliance specifications.NOTE 2 Transformers covered by this part may be flush or surface mounted or incorporated in luminaires,mirrors, and other equipment containing one or more socket-outlet(s).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.
