Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 5273-1985 "Terminals for transformers, high voltage electrical appliances and sleeves".

The main technical differences between this standard and GB/T 5273-1985.

- Terminals are removed from the terms and definitions, with high voltage terminals and terminal connectors added (see Chapter 2);

- modify the dimensions of the terminal (see 1985 version 3.2) by modifying the dimensions in the type and size, such as a2 (see 3.3);

- Removed single-hole type terminals in type and size (see 1985 version 3.2), with screw-shaped terminals and 16-hole plate terminals (See 3.3);

- The recommended value of the connection terminal size and its connection method for the rated current selection is given in Appendix A and Appendix B "Terminals (See Appendix A, Appendix B, 1985).

This standard uses the re-drafting method to modify the use of IEC/T R62271-301..2009 "High Voltage Switchgear and Control Equipment Part 301 Points. high-voltage terminal size standardization. " the main technical differences between this standard and IEC/T R62271-301..2009.

- to increase the normative reference documents GB/T 14315-2008, GB 50149-2010;

--- According to China's actual, in the type and size of the screw-shaped terminals, screw-shaped terminals and sixteen-hole plate-shaped terminals;

- according to our actual situation, in the plate-shaped terminal to increase the hole center to the edge of the vertical recommended size a1, hole center to the root of the longitudinal Size a2;

--- According to China's reality, in some of the board-shaped terminal to increase the size of phi18 × 60;

--- According to China's needs, an increase of "Chapter 4 technical requirements." this standard has made the following editorial changes.

--- Standard name is changed from "High voltage switchgear and control equipment Part 301. High voltage terminal size standardization" to "High voltage electrical appliances Terminal size standardization ".

This standard is proposed by China Electrical Equipment Industry Association.

This standard by the National High Voltage Switchgear Standardization Technical Committee (SAC/TC65) centralized.
