This section GB/T 19212 Part 16. 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 Part replaces GB/T 19212.16-2005 "Safety of power transformers, power supply units and similar products Part 16. Medical field Particular requirements for isolation transformers for power supply ". Compared with GB/T 19212.16-2005, the main technical changes are as follows. --- Standard name changed to "transformers, reactors, power supply and its combination of safety Part 16. Medical premises power supply with isolation Transformer special requirements and tests "; --- Modify the scope of the provisions (see Chapter 1); --- Modify the normative references (see Chapter 2); --- Modify the terms "isolation transformer for medical premises power supply" and "functional shielding" is defined, the term "no-load input power Flow "(see Chapter 3); --- Increase the requirements of signs and other information (see Chapter 8); 1) Some of the standards in this series are under the heading "Safety of Power Transformers, Power Supplies, Reactors and Similar Products" and some are under the heading "Supply Voltage Under the heading "Safety of transformers, reactors, power supply units and similar products up to and including 1100V" under the heading "Transformers, Reactors, Power Source device and its combination of security "heading, the title of the series of standards released in the future may be modified. --- Modify the short-circuit voltage and inrush provisions (see Chapter 13); --- Added additional heating test requirements (see 14.101); --- Increase the short circuit and overload protection requirements (see Chapter 15); --- Modify the insulation resistance, dielectric strength and leakage current requirements (see Chapter 18); --- Modify the provisions of the structure (see Chapter 19); --- Removed Appendix C and Appendix D (see.2005 version of Appendix C and Appendix D); --- Added Appendix H, modified Appendix L (see Appendix H and Appendix L). This section uses the redrafted law to amend the use of IEC 61558-2-15.2011 "transformers, reactors, power devices and their combination of security All sections 2-15 - Particular requirements and tests for isolating transformers for the supply of medical premises ". This section there are technical differences compared with IEC 61558-2-15.2011, all of these differences are due to this part of the supporting standards GB/T 19212.1-2016 and IEC 61558-1.2009 in Chapter 2 arising from the technical differences arising. This section also made editorial changes, the IEC 61558-2-15.2011 6.1 ~ 6.4 to 6.101 ~ 6.104. This part is proposed by China Electrical Equipment Industry Association. This part of the national small-scale power transformers, reactors, power devices and similar products Standardization Technical Committee (SAC/TC418) Focused. This part of the drafting unit. Shenyang Transformer Research Institute Co., Ltd., National Broadcasting and Television Product Quality Supervision and Inspection Center, Shanghai Quality Supervision and Inspection Institute of Technology, Ministry of Industry and Information Technology Institute of the Fifth Institute for Quality and Safety Testing Center Bao.

Transformers, Reactors, Power Supplies and Their Combinations Part 16. Isolation transformers for the supply of medical premises Special requirements and tests1 ScopeThis clause GB/T 19212.1-2016 is replaced by the following. This part of GB/T 19212 specifies the safety requirements for isolation transformers for medical premises. Note 1. Safety requirements include electrical, temperature and mechanical aspects. Unless otherwise specified, the following "transformers" include isolation transformers for the supply of medical premises. This section applies to standing, single-phase or three-phase, air-cooled (self-cooled or air-cooled) Group II medical IT systems for medical power supply Independent dry isolation transformer. It is permanently connected to the fixed wire of the IT system on the secondary side. Winding can be encapsulated or not Closed. Note 2. IT power system requirements see GB/T 16895.1. Note 3. The installation procedures for Group II medical IT system medical facilities are contained in GB/T 16895.24. Note 4. This section relates to the transformer used for medical places power supply. All other transformers or equipment connected downstream of the transformer are not included in this section In points. Rated power supply voltage does not exceed AC 1000V, rated power frequency and internal operating frequency does not exceed 500Hz. For single-phase and three-phase transformer rated output of not less than 0.5kVA, and not more than 10kVA. This section also applies to transformers that do not limit the rated output if the purchaser and the manufacturer otherwise agree. Note 5. This section does not include transformers to be supplied to the distribution network. For single-phase or three-phase transformers (phase voltage), no-load output voltage and rated output voltage does not exceed 250VAC. This section does not apply to the power supply device. This section does not apply to the external circuit to be connected with the input and output terminals of the transformer and its components. When installing procedures or electricity This specification requires the use of the transformers included in this section when double insulation or reinforced insulation between circuits is required. Note 6. Note the following. --- Additional requirements (other applicable standards, national codes, etc.) may be required for transformers intended for use on vehicles, ships or aircraft; --- Should consider taking protective measures to avoid the external components such as molds, pests, termites, solar radiation and icing in the shell and shell; --- Should consider the transformer transport, storage and work of different conditions; --- For transformers scheduled to be used in special environments, additional requirements may be used in accordance with other applicable standards and national regulations.2 Normative referencesExcept for the following quotations, the chapter GB/T 19212.1-2016 applies.
