GB/T 23371.3-2009Basic principles for graphical symbols for use on electrical equipment -- Part 3: Guidelines for the application of graphical symbols (English PDF)

Foreword

GB/T 23371 "Electrical Equipment Basic principles for graphical symbols" and GB/T 5465 "Graphical symbols for electrical equipment" constitute support Graphical symbols for electrical equipment with a series of national standards.

GB/T 23371 "Electrical Equipment Basic principles for graphical symbols" is divided into four parts.

--- Part 1. Creation of symbol originals (IEC 80416-1);

--- Part 2. Form and use of arrows;

--- Part 3. Application guide (IEC 80416-3);

--- Part 4. Screen display devices applicable rules and graphical symbols (icons) of.

This section GB/T 23371 Part 3.

This section identical with IEC 80416-3:2002 "device with the basic rules of graphical symbols - Part 3. Application Guidelines" (in English), and IEC 80416-3:2002, compared to 4.4 instead of the standard provisions of international standards.

This standard is closely associated with the GB/T 5465 "Graphical symbols for electrical equipment" is divided into two parts.

--- Part 1. Overview and classification (IEC 60417DB);

--- Part 2. Graphical symbols (IEC 60417DB).

This information structure in part by the National Electrical documentation and graphical symbols Standardization Technical Committee (SAC/TC27) and focal points.

Introduction

Graphic symbols is a language-independent graphical visual perception, used to express certain information. Graphical symbols for electrical equipment with a wide of uses. In the design for a series of symbols with spaces or similar device, the symbol of consistency is very important when these symbols narrow the size is very small, it is equally important to clearly legible. Therefore, it is necessary to form an electrical equipment standardization Principles of graphical symbols to to maintain consistency and ensure symbol symbols visual clarity, thereby increasing the symbol of recognizability.

This standard is proposed to generate graphical symbols for electrical equipment basic rules, including line width, shape, and use arrows, negative elements and groups the pattern of use, etc., used as a guide to draw the device symbol. These design principles apply to all electrical equipment Graphical symbols. that is, from Graphic GB/T 5465 and ISO 7000 standardized symbols.

This section gives a graphical symbol required when used in special circumstances in electrical equipment guidelines to support documentation and other standard.
