This section GB/T 19212 Part 27. This section is based on the GB/T 19212.1-2016 developed on the basis of this section Need to be used with GB/T 19212.1-2016. This section is GB/T 19212.1-2016 the corresponding chapter, Article supplement and repair Change in order to GB/T 19212.1-2016 content into the contents of this section. This section is for GB/T 19212.1-2016 added the added content starts from 101.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This section uses the redrafted law to amend the use of IEC 61558-2-26:2013 "transformers, reactors, power supply units and combinations of safety Part 2-26. Particular requirements and tests for transformers and power supply units for energy conservation and other purposes ".

This section compared with IEC 61558-2-26:2013 there are technical differences, all of these differences are due to the standard part of this standard GB/T 19212.1-2016 and IEC 61558-1:2009 in Chapter 2 arising from the technical differences arising.

1 Scope

This clause GB/T 19212.1-2016 is replaced by the following.

This section GB/T 19212 specifies the safety requirements for energy-saving and other purposes with transformers, power supply units and switching power supply units, in electrical installations, energy savings and other purposes are achieved by adjusting the output voltage and/or other electrical characteristics of the output circuit, free from transformers, Power supply and switching power supply unit interrupts.

Note 1. Safety requirements include electrical, temperature and mechanical aspects.

Energy saving is achieved through voltage stabilization and/or voltage regulation of the electrical installation. This standard can also be used to adjust the voltage or scheduled the final adjustment of other electrical characteristics of the power supply and switching power supply unit.

Note 2. Lighting for outdoor or indoor use is an example of an electrical installation.

Note 3. The reduction of output voltage in some special applications may affect the safety and performance of power supply equipment.

This section applies to single-phase or three-phase, air-cooled (self-cooled or air-cooled), independently or with the following GB/T 19212 series of standards Energy-saving transformers, power supply units and switching power supply units for the provision of transformers and/or power supply units.

--- Part 2. Particular requirements and tests for power supply units for general purposes separation transformers and built-in separation transformers;

--- Part 5. Particular requirements and tests for isolating transformers and power supply units incorporating isolating transformers;

--- Part 7. Particular requirements and tests for power supply units for safety-isolated transformers and built-in safety isolating transformers;

--- Part 14. Particular requirements and tests for autotransformers and power supply units incorporating autotransformers;

--- Part 15. Particular requirements and tests for the power supply of voltage regulators and built-in voltage regulators;

--- Part 17. Particular requirements and tests for transformers for switching power supply units and switching power supply units.

Rated supply voltage does not exceed AC 1000V, rated power frequency does not exceed 500Hz.

This section applies to the internal frequency does not exceed 500Hz linear power supply unit.

This section GB/T 19212.17 combined with the use, but also for internal work frequency of more than 500Hz energy-saving switching power supply unit Set and transformer.

GB/T 19212 series for the other part of the corresponding specific application, in addition to the requirements listed in this section, the corresponding necessary requirements be applicable.

When the two requirements conflict, priority is given to the most stringent requirements.

Rated output does not exceed.

--- 150kVA, for single-phase energy-saving transformers, power supply and switching power supply unit;

--- 400kVA, for three-phase energy-saving transformers, power supply and switching power supply unit.

This section also applies to energy-saving transformers, power supply units, and power supply units not limited to the rated output if purchaser and manufacturer have otherwise agreed Switching power supply unit.

This section does not apply to be scheduled to be connected to the energy-saving transformer, power supply and switching power supply input terminals and/or output External circuit of the terminal and its components.

This section does not apply to other devices with similar functions, such as dual-level control devices, electronic control devices and other standard packages Special lighting regulator included.

Protection against external influences such as molds, pests, termites, solar radiation and icing on components in the enclosure and enclosure should also be avoided
