This part is part 15 of GB/T 19212. This part is in GB/T 19212.1-2016 (IEC 61558-1.:2009, MOD) based on the development of this part with the use of GB/T 19212.1-2016. This section is for GB/T 19212.1-

2016 The newly added content starts with number 101.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This part uses the re-drafting method to modify the use of IEC 61558-2-14.:2012 "Transformers, reactors, power supply units and their combinations Part 2-14. Particular requirements and tests for power supply units for regulators and internal regulators ".

The technical differences between this section and IEC 61558-2-14.:2012 are as follows.

Replace IEC 61558-1.:2009 with GB/T 19212.1-2016 with international standard.

1 Scope

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

This part of GB/T 19212 specifies the safety of general purpose voltage regulators and power supply units incorporating general purpose voltage regulators.

Transformers with built-in electronic circuits are also included in this section.

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

Unless otherwise specified, the following "transformers" include general purpose voltage regulators and power supply units with built-in general purpose voltage regulators.

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

This section applies to "transformers" and power supply units (linear) where the internal operating frequency does not exceed 500 Hz.

This part is used in conjunction with GB 19212.17 switch type power supply unit. It is also suitable for power supply with internal operating frequency exceeding 500Hz.

Set. When the requirements of the two standards are inconsistent, the more stringent standards are preferred.

This part does not apply to transformers included in GB 1094.11.

This part applies to standing or mobile, single or multi-phase, air cooling (self-cooling or air-cooled), independent or matching with dry "change Pressure device ".

- Autotransformer and built-in autotransformer power supply device;

- Separate voltage regulator and built-in separate power supply device;

--- isolation regulator and built-in isolation regulator power supply device;

- Safe isolation regulator and power supply unit with built-in safety isolating voltage regulator.

Windings may be enclosed or non-encapsulated.

Rated output no more than.

--- 40kVA, single-phase autotransformer and built-in single-phase autotransformer power supply device;

---.200kVA, multi-phase autotransformer and built-in multi-phase autotransformer power supply device;

--- 1kVA, single-phase separation regulator and built-in single-phase separation of the power supply device;

--- 5kVA, multi-phase separation regulator and built-in multi-phase separation of the power supply device;

--- 25kVA, single-phase isolation regulator and built-in single-phase isolation regulator power supply device;

--- 40kVA, multi-phase isolation voltage regulator and built-in multi-phase isolation regulator power supply device;

--- 10kVA, single-phase safe isolation regulator and built-in single-phase safe isolation regulator power supply device;

--- 16kVA, multi-phase safe isolation regulator and built-in multi-phase safe isolation regulator power supply device.

This part also applies to "transformers" that are not limited to rated outputs when agreed between the purchaser and the manufacturer.

Note 2. This range does not include "transformers" intended to be used for distribution networks.

For autotransformer and built-in autotransformer power supply device.

--- No-load output voltage or rated output voltage should not exceed AC 1000V or no ripple DC 1415V;

--- independent transformer "transformer", the rated output voltage should be more than AC 50V or no ripple DC 120V but not more than AC 250V.

Note 3. In general, the autotransformer and the power supply unit are intended to be used in conjunction with the equipment to provide a different power supply voltage for the functional requirements of the equipment Pressure. The electric shock protection can be provided by other parts of the ancillary equipment, for example. shell.
