28、r auto transformers and power supply units incorporating auto transformers 1 Scope Replacement: This part of IEC 61558 deals with the safety of auto transformers for general applications and power supply units incorporating auto transformers for general applications. Transformers incorporating elect
29、ronic 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 auto transformers for general applications and power supply units incorporating auto transformers for general
30、 applications. NOTE 2 : For power supply units (linear) this part is applicable. For switch mode power supply units, IEC 61558-2-16 is applicable together with this part. This part is applicable to stationary or portable, single-phase or polyphase, air-cooled (natural or forced) independent or assoc
31、iated dry- type transformers. The windings may be encapsulated or non-encapsulated. The rated supply voltage does not exceed 1 100 V a.c., and the rated supply frequency and the internal operating frequencies do not exceed 500 Hz. The core power does not exceed: 2 kVA for single-phase transformers;
32、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 rated output both being subject to an agreement between the purchaser an
33、d the manufacturer. Where applicable, the no-load output voltage or the rated output voltage does not exceed 1 000 V a.c. or 1 415 V ripple-free d.c., and for independent transformers, the no-load output voltage and the rated output voltage exceeds 50 V a.c., or 120 V ripple-free d.c. This part is n
34、ot applicable to external circuits and their components intended to be connected to the input terminals and output terminals of the transformers. Transformers covered by this part are used only in applications where no insulation between circuits is required by the installation rules or by the end p
35、roduct standard. NOTE 3 Attention is drawn to the following: BS EN 61558-2-13:200961558-2-13 IEC:2009 7 for transformers intended to be used in vehicles, on board ships, and aircraft, additional requirements (from other applicable standards, national rules, etc.) may be necessary; measures to protec
36、t the enclosure and the components inside the enclosure against external influences such as fungus, vermin, termites, solar-radiation, and icing should also be considered; the different conditions for transportation, storage, and operation of the transformers should also be considered; additional re
37、quirements in accordance with other appropriate standards and national rules may be applicable to transformers intended for use in special environments. NOTE 4 Future technological development of transformers may necessitate a need to increase the upper limit of the frequencies, until then this part
38、 may be used as a guidance document. 2 Normative references This clause of Part 1 is applicable except as follows.

For independent transformers, the rated output voltage shall exceed 50 V a.c. or
43、120 V ripple-free d.c. 6.102 The rated output shall not exceed: 40 kVA for single-phase transformers; 200 kVA for polyphase transformers.

The relation between the core power and the rated output is given in the following formula: Vmax- VminCore power (VA) = rated output (VA) Vmaxwhere Vmaxand Vminare the highest and lowest values (rated
46、 supply voltage or rated output voltage). NOTE In this case, the limitation of the core power is applicable to the rated output. This formula is not applicable to a transformer with separate windings which are electrically connected (see Figure 103). In this case, the core power of the transformer i
