When revising GB/T4728.1, it is intended to adopt IEC60617-1 as an equivalent. The Appendix B and Appendix C of the original IEC60617-4:1996 are French and English indexes respectively, which are deleted in this standard. Appendix B of this standard is the symbols added in GB/T4728.4-1985 that are not in the original IEC60617-4 (1st edition). Both Appendix A and Appendix B of this standard are informative appendices. This standard replaces GB/T4728.4--1985 from the date of implementation. This standard is proposed and managed by the National Technical Committee for Electrical Document Preparation and Graphic Symbols Standardization. This standard was drafted by the Mechanical Science Research Institute of the Ministry of Electrical Machinery Industry. The main drafters of this standard are: Guo Ting, Li Shilin, Gao Huimin, Meng Qinglan, Yin Tao, Wei Yanjun, Li Ling. This standard was first issued on May 15, 1985. -13 GB/T4728.4-1999 IEC Foreword 1) IEC (International Electrotechnical Commission) is a world-wide standardization organization that includes all national electrotechnical committees (IEC National Committees). The goal set by 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 formulation of international standards is entrusted to technical committees. Any IEC National Committee can participate in the standard formulation work if it is interested in the subject being studied. International organizations, governments and non-governmental organizations that have relations with IEC can also participate in the standard formulation work. IEC and ISO work closely under the conditions determined by the agreement between them. 2) IEC formal decisions and agreements on technical matters, drawn up by technical committees attended by those national committees particularly concerned with these matters, expressing as far as possible an international consensus on the subject matter involved. 3) They are accepted by the national committees in the sense that they are published in the form of standards, technical reports or guidelines and recommended for international use. 4) In order to promote international unity, the IEC national committees undertake the task of applying IEC international standards to the greatest extent possible in their countries and regions. Any differences between IEC international standards and corresponding national or regional standards should be clearly indicated in the latter. International Standard IEC60617-4 was drafted by Technical Committee 3A (Graphical Symbols for Diagrams) of IEC Technical Committee 3 (Documentation and Graphical Symbols). This second edition abolishes 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 (FDIS) 3A/382/FDIS Voting Full information on this standard can be found in the voting report mentioned in the table above. Appendix A, Appendix B and Appendix C are for reference only. i Voting Report 3A/420/RVD GB/T 4728. 4-—1999 IEC Introduction This part of IEC60617 constitutes a part of the series of graphic symbols for schematic diagrams. The series consists of the following parts: Part 1 Part 2 Part 3 Part 4 Part 5 Part 6 Part 7 Part 8 Part 9 Part 10 Part 11 Part 12 Part 13 General Information, General Index, Comparison Table Symbol Elements, Qualifying Symbols and Other commonly used symbols Conductors and connectors Basic passive components Semiconductor tubes and electron tubes Generation and conversion of electrical energy Switchgear, control equipment and protection devices Measuring instruments, lamps and annunciators Telecommunications: switching and peripheral equipment Telecommunications: transmission Architectural and surveying installation drawings and schematics Binary logic elements Analog components The scope and reference standards of this series are shown in IEC60617-1. The above symbols are designed according to the requirements of ISO11714-1* to be published. The module used is M-2.5mm. In order to make smaller symbols clearer, these symbols are enlarged by half in this standard and marked with "200%" in the symbol column; in order to save space, larger symbols are reduced by half and marked with "50%\" in the symbol column. In order to facilitate the drawing of multiple terminals and meet other layout requirements, the size of the symbol (such as height) can be changed in accordance with Article 7 of ISO11714-1. Regardless of whether the size of the symbol is enlarged, reduced or corrected, the original line width is not corrected proportionally. The symbol layout of this standard should make the distance between the connecting lines a multiple of a certain module. 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 the same grid is used uniformly when drawing all symbols. In computer-aided drawing systems, all symbols should be drawn within the 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 IEC60617-4 had a transition period, and they are no longer included in the second edition. Part, and it will be made clear that they are no longer in use. The index to Annexes B and C contains an alphabetical index of the symbol names and their numbers, the symbol names being based on the description of the symbols in this part. A general alphabetical index of the symbols of all parts is given by IEC 60617-1. * Currently, it is still at the draft international standard stage (Document 3/563/DIS). 45 Resistors 04-01-01 04-01-02||tt| |04-01-03 04-01-04 04-01-05 04-01-06 04-01-07 04-01-08 04-01-09 04-01-10 National Standard of the People's Republic of China Graphical Symbols for Electrical Schematics Part 4: Basic Passive Components Graphical symbols for diagramsPart 4:Basic passive componentsPart 1 Graphic symbols Approved by the State Administration of Quality and Technical Supervision on 1999-03-2346 Resistors, capacitors, inductors GB/T 4728. 4-1999 idt IEC 60617-4: 1996 Replaces GB/T4728.4--1985 Resistors, general symbols Go to Appendix A:04-A1-01 Adjustable resistors Varistor Variator Resistors with sliding contacts Resistors with sliding contacts and disconnect positionPotentiometers with sliding contacts Potentiometers with sliding contacts and preset potentiometers Resistors with fixed taps Showing two taps Shunters Resistors with shunt and voltage dividing terminals 1999-10-01Implementation 04 -01-11 04-01-12 Capacitor 04-02-01 04-02-02 04-02-03 04-02-04 04-02-05 04-02-06||tt ||04-02-07 04-02-08 04-02-09 04-02-10 0 4-02-11 04-02-12 04-02-13 04-02-14 GB/T 4728.4 Graphic Symbols Graphic Symbols Carbon Stack Resistors Heating Elements Capacitors, General Symbols Go to Appendix A: 04-A2-01 Feedthrough Capacitors Bypass Capacitors Go to Appendix A: 04-A2-02 Polarized Capacitors, E.g., Electrolytic Capacitors Go to Appendix A: 04-A2-03 Adjustable Capacitors Go to Appendix A: 04-A2-04 Pre-adjusted Capacitors Go to Appendix A: 04-A2-05 Differentially Adjustable Adjustable capacitor Go to Appendix A: 04-A2-06 Stator-separated adjustable capacitor Go to Appendix A: 04-A2-07 04-02-15 04-02-16 Inductor 04-03-01 04-03-02 04-03-03 04-03-04 04·03-05 04-03-06 04-03-07 04-03-08 04-03-09 GB/T 4728.4 Graphic symbols Graphic symbols Thermosensitive polar capacitor Use its thermosensitive characteristics, such as ceramic capacitors Varistor-sensitive polar capacitor Use its varistor characteristics, such as semiconductor capacitors Inductor Choke If it represents an inductor with a magnetic core, a parallel line can be added to the symbol.
