適用范圍

This standard applies to dry-type power transformers (including auto-transformers) having values of highest voltage for equipment up to and including 36 kV. The following small and special dry-type transformers are not covered by this standard: — single-phase transformers rated at less than 1 kVA and polyphase transformers rated at less than 5 kVA; — instrument transformers (covered by IEC Publications 185: Current Transformers, and 186: Voltage Transformers); — transformers for static convertors (covered by IE C Publications 84: Recommendations for Mercury-arc Convertors, 119: Recommendations for Polycrystalline Semiconductor Rectifier Stacks and Equipment, and 146: Semiconductor Convertors); — starting transformers; — testing transformers; — traction transformers mounted on rolling stock; — flameproof and mining transformers; — welding transformers; — voltage regulating transformers; — small power transformers in which safety is a special consideration. Where IEC standards do not exist for the transformers mentioned above or for other special transformers, this standard may be applicable as a whole or in parts. With the publication of this standard, the requirements of IEC Publication 76 apply to dry-type transformers only in so far as they are referred to in this standard. Where reference is made to specific clauses and sub-clauses of various parts of IE C Publication 76, it is to be understood that the editions are as follows: 76-1, 76-2, 76-4, 76-5: 1976. 76-3: 1980.
