Abstract of International Standards and Adoption of Electronic Transformers and Inductors: A brief description of the status of IEC international standards for electronic transformers and inductors, and discussion of the use of IEC international standards for national standards and electronic industry standards. 1 Overview Electronic transformers are small and medium-sized transformers other than power transformers. They are mainly used in communication and electronic equipment. They play the role of electromagnetic energy conversion, isolation and impedance matching in electronic circuits. They are an irreplaceable in information industry technology. The basic function of the magnetic components. Due to the variety of electronic transformers, many specifications, and many production and use units, with the development of commodity exchange and market economy, and the speeding up of the adoption of international standards after China's accession to the WTO, the standardization of electronic transformers is becoming more and more important. More and more urgent. In order to promote the comprehensive development of electronic transformer standardization work, we briefly analyze the IEC international standards and adoption of electronic transformers, and introduce the current national standards for electronic transformers and inductors, electronic industry standards and national military standards. 2 The development of international standards for electronic transformers and the international standards for electronic transformers are formulated by the Technical Committee of the 51st Technical Committee (TC51) "Magnetic Components and Ferrite Materials" of the International Electrotechnical Commission (IEC), specifically by TC51 Working Group 9 ( WG9) “Emotional Component Group†is responsible for and organizes drafting. The national standardization technical organization corresponding to IEC/TC51 is CSBTS/TC89 “National Magnetic Components and Ferrite Materials Standardization Technical Committeeâ€. The National Magnetic Standards Committee is entrusted by the State Council Standardization Administration and the Ministry of Information Industry to undertake the domestic IEC/TC51 international standards. The technology is in charge of the work, and undertakes the organization and technical review of national standards and industry standards in the professional fields of magnetic components and ferrite materials. 3 International Standards and Adoption of Electronic Transformers and Inductors Since electronic transformers and inductors are both “inductive components†and are also developed by IEC/TC51 Working Group 9, the following is a summary of electronic transformers and inductors. Introduction. 3.1 International Standards and Adoption of Electronic Transformers and Inductors There are 60 standards of IEC/TC51 so far, of which only 15 are electronic transformers and inductors, accounting for 25% of the entire standard. The name of the specific standard And the use situation is shown in Table 1. As can be seen from Table 1, 11 of the 15 international standards for electronic transformers and inductors are adopted as corresponding national standards or industry standards, and the adoption rate is 73.3%, of which 5 are equivalent to the IEC standard. There are 6 IEC/TC51 (Sec) documents (GB/T14860-1993, SJ/T10615-1995, GB/T15183-1994, GB/T15184-1994, SJ/T16014-1995, SJ/T16015-1995), which The six adopted IEC/TC51 (Sec) documents are intermediate files in the formation of the current IEC official standards. There are currently 4 IEC standards not used as corresponding national or industry standards.
