Safety of transformers, reactors, power supply units and combinations thereof. Part 2-26: Particular requirements and tests for transformers and power supply units for saving energy and other purposes (IEC 61558-2-26:2013)

Alkalmazási terület

Replacement: This part of IEC 61558 deals with the safety of transformers, power supply units and switch mode power supply units all for saving energy and other purposes in electrical installations by adjusting the output voltage and/or other electrical characteristics on the output circuits without interruption affected by the transformers, power supply unit and switch mode power supply unit. NOTE 1 Safety includes electrical, thermal and mechanicals aspects. The saving of energy is obtained by voltage stabilization and/or voltage adjusting of the electrical installation. This standard may also be used for power supply units and switch mode power supply units intended to be used where adjusting of the voltage or other electrical characteristics is required by the final application. NOTE 2 An example of electrical installation is lighting installations, outdoor or indoor. NOTE 3 In special applications the reduction of the output voltage may affect the safety and the performance of the supplied equipment. This part applies to single-phase or three-phase transformers, power supply units and switch mode power supply units all for saving energy which are air-cooled (natural or forced), independent or incorporated and containing transformers and/or power supply units from the following parts of the IEC 61558 series: Part 2-1: Particular requirements and tests for separating transformers and power supplies incorporating separating transformers for general applications. Part 2-4: Particular requirements and tests for isolating transformers and power supply units incorporating isolating transformers. Part 2-6: Particular requirements and tests for safety isolating transformers and power supply units incorporating safety isolating transformers. Part 2-13: Particular requirements and tests for auto transformers and power supply units incorporating auto transformers. Part 2-14: Particular requirements and tests for variable transformers and power supply units incorporating variable transformers. Part 2-16: Particular requirements and tests for switch mode power supply units and transformers for switch mode power supply units. The rated supply voltage does not exceed 1 000 V a.c., and the rated supply frequency does not exceed 500 Hz. This standard is applicable to linear powers supply units with internal operational frequency not exceeding 500 Hz. This standard in combination with part 2-16 is also applicable to switch mode power supply unit and transformer all for saving energy with internal operating frequency higher than 500 Hz. For specific application corresponding to the other parts 2 of IEC 61558 series, the necessary requirements of the relevant parts 2 are applicable. In addition, the requirements listed in this part apply. When two requirements are in conflict, the most severe take precedence. The rated output does not exceed: – 150 kVA for single-phase transformer, power supply unit and switch mode power supply unit all for saving energy; – 400 kVA for three-phase transformer, power supply unit and switch mode power supply unit all for saving energy. This part is also applicable to transformer, power supply unit and switch mode power supply unit all for saving energy without limitation of the rated output subject to an agreement between the purchaser and the manufacturer. The standard is also not applicable to external circuits and their components intended to be connected to the input terminals and/or output terminals of the transformer, power supply unit and switch mode power supply unit all for saving energy. This standard is not applicable to other devices having similar functions, for example double level control gears, electronic control gears and specific dimmers covered by other standards. Measures to protect the enclosure and components inside the enclosure against external influences such as fungus, vermin, termites, solar-radiation, and icing shall also be considered. The different conditions for transportation, storage, and operation of the transformer, power supply unit and switch mode power supply unit all for saving energy shall also be considered. Additional requirements in accordance with other appropriate standards and national rules may be applicable to transformer, power supply unit and switch mode power supply unit all for saving energy intended for use in special environments, such as tropical environment.
