This standard replaces GB/T4728.101985 from the date of entry into force. This standard is proposed and managed by the National Technical Committee for Standardization of Electrical Documents and Graphical Symbols. This standard was drafted by the Post and Telecommunications Industry Standardization Institute of the Ministry of Posts and Telecommunications and the Mechanical Research Institute of the Ministry of Machinery Industry. The main drafters of this standard are Sheng Wei, Guo Ting and Yin Tao. This standard was first published in May 1985. GB/T4728.10-1999 IEC Foreword 1) IEC (International Electrotechnical Commission) is a worldwide standardization organization including all national electrotechnical technical committees (IEC National Committees). The stated objective of IEC is to promote international cooperation on various issues related to standards in the electrical and electronic fields. For this purpose and other activities, IEC also publishes international standards. The development of international standards is entrusted to technical committees. Any IEC National Committee may participate in the development of standards if it is interested in the subject under study. International, governmental and non-governmental organizations may also participate in the development of standards in liaison with the IEC. The IEC and the International Organization for Standardization (ISO) work closely under the conditions determined by agreement with ISO. 2) Formal IEC resolutions or agreements on technical issues are developed by technical committees in which national committees with special interest in these issues participate, and express international consensus on the subject under study as far as possible. 3) They are published in the form of standards, technical reports or guidelines and recommended for international use, in the sense that they are accepted by the National Committees. 4) In order to promote international unification, the IEC National Committees undertake the task of applying IEC International Standards to the greatest extent possible in their national and regional standards. Any differences between IEC International Standards and the corresponding national or regional standards shall be clearly indicated in the latter. International Standard IE60617-10 was drafted by Technical Committee 3A (Graphical Symbols for Diagrams) of IEC Technical Committee 3 (Documentation and Graphical Symbols). This second edition cancels and replaces the first edition of 1983 and is technically revised. The text of this standard is based on the following documents: Draft International Standard 3A(CO)170 3A(CO)203 3A/388/FDIS Voting Full information on this standard can be found in the voting report mentioned in the table above. Appendix A is for reference only. Voting Report 3A(CO)179 3A(CO)205 3A/426/RVD GB/T 4728.10-1999 This part of IEC 60617 forms part of the series of graphic symbols for diagrams. The series consists of the following parts: Part 1 General information, general index, cross-reference tablePart 2 Part 3 Part 4 Part 5 Part 6 Part 7 Part 8 Part 9 Part 10 Symbol elements, qualifiers and other commonly used symbolsConductors and connectors Basic passive components Semiconductor tubes and circuits Sub-tubes Generation and conversion of electrical energy Switchgear, controlgear and protection devices Measuring instruments, lights and annunciators Telecommunications: switching and peripheral equipment Telecommunications: transmission Part 11 Part 12 Architectural and surveying installation drawings and schematics Binary logic elements Part 13 Analogue components The scope of this series and the standard references are shown in 1EC60617-1. The above symbols are designed according to the requirements of ISO11714-1 to be published, and the adopted modulus M=2.5mm. In order to make smaller symbols clearer, these symbols are enlarged by one time in this standard, and marked with "200%\" in the symbol column; in order to save format, larger symbols are reduced by one time and marked with "50%" in the symbol column. In order to facilitate the drawing of multiple terminals and other layout requirements, the size of the symbol (such as height) can be modified in accordance with Article 7 of ISO117141. Regardless of whether the size of the symbol is enlarged, reduced or modified, the width of the original line is not modified proportionally. The symbol layout of this standard should make the distance between the connecting lines a multiple of a certain modulus. In order to facilitate the marking of the terminals, 2M is usually selected. For ease of understanding, the symbols are drawn at a certain size, and when drawing all the symbols, The same grid is used uniformly. In computer-aided drawing systems, all symbols should be drawn within a grid, and the grid used is reproduced on the background of the symbol. The old symbols included in Appendix A of the first edition of IEC60617-10 have a transition period. This part is no longer included in the second edition, and it will be made clear that they are no longer used. The index of Appendix B and Appendix C includes an alphabetical index of the symbol name and its number. The symbol name is based on the description of the symbol in this part. The general index of the alphabetical order of symbols of all parts is given by IEC60617-1. *Currently, it is still in the draft international standard stage (Document 3/563/DIS). 203 National Standard of the People's Republic of China Graphical symbols for diagrams Part 10: Telecommunications: Transmission Part I Telecommunication circuits Line and circuit use GB/T4728.10 --1999 idt IEC 60617-10:1996 replaces GB/T4728.101985 The symbol 03-01-01 is used to represent a line or other various telecommunication circuits.
