GB/T 28028-2011Criteria for assessing and coding of the commutation of rotation electrical machines for traction (English PDF)

Foreword

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

This standard uses the redrafted law revision adopted IEC 60638. 1979 "Traction motor reversing rotation direction evaluation and coding guidelines." this standard and IEC 60638. 1979 technical differences exist, these differences involve the terms of the margin with a single vertical line (-) into Row marked. This standard and IEC 60638. 1979 technical differences and the reasons given in Appendix A.

This standard and IEC 60638. 1979 structural changes as follows, according to GB/T 1.1-2009 requirements, changing the original chapter number.

--- The standard adds Chapter 2, "Normative references";

--- The standard Chapter 3, Chapter 4, corresponding to the original;

--- The standard Chapter 4, corresponding to the description in Chapter 2;

--- The standard Chapter 5 corresponding to the original Chapter 3;

--- The standard Chapter 6 - Chapter 14, followed by the corresponding original Chapter 5 - Chapter 13;

--- Increase in Appendix A, the original Appendix A to Appendix B.

This standard also made the following editorial changes.

--- The original illustrations (actually a table) changed its name to the corresponding provisions of the corresponding section of the table, arranged in order of Tables 1 to 6, for ease of viewing and comparing Tables 1 to 6 maintain their position unchanged; the original table I now table 7, on the back of Table 6;

--- IEC 60638. 1979 English page 19 (Chapter 11) in the penultimate line, "slotpitch (singleordouble)", by comparison the French version, should be "polepitch (singleordouble)". The standard (Chapter 12) be amended to read "the pole pitch (single or double Times the pole pitch) ";

--- IEC 60638. 1979, there is no clear its appendices "spark observed with variable opacity wedge" in nature. Given that Appendix Content is not necessary to perform this standard will be identified as informative appendices.

The standard proposed by the People's Republic of China Ministry of Railways.

This standard by the national electric traction equipment and systems Standardization Technical Committee (SAC/TC278) centralized.

This standard is mainly drafted by. CSR Zhuzhou Electric Co., Ltd..

Participated in the drafting of this standard. new speed Yongji Electric Appliance Co., Ltd., Zhuzhou CSR Times Electric Co., Ltd.

1 Scope

This standard applies to GB/T 25123.1 and has covered all motor cylindrical commutator.

This standard is to improve the following aspects GB/T 25123.1.

--- Commutation assessment criteria;

--- During the test should be defined to observe trials;

--- Detailed description of these observations for the recommended code.

This standard does not consider the traction motor slip ring.
