Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard uses redrafted law revision adopted IEC 62499.2008 "rail transit flow system pantograph carbon skateboard test side law". This standard compared with IEC 62499.2008 in the structure of more adjustment, the specific chapter number control see Appendix A. This standard compared with IEC 62499.2008 there are technical differences, the provisions of these differences have been passed in the outer margin of the page margin Set the vertical single line (︱) were marked, the technical differences and the reasons are as follows. --- Increasing the normative references, due to the text changes cited (see 5.2.2); --- Modify and add the relevant symbols (see Chapter 4, Chapter 4 of IEC 62499.2008); --- Increased the size of the inspection, with reference to TB/T 1842.3-2008 improve the pilot project (see 5.2.1); --- Increase the carbon performance test, with reference to TB/T 1842.3-2008 improve the pilot project (see 5.2.2); --- Increased carbon skateboard at the maximum operating temperature of the current-carrying capacity test to improve the stability of carbon skateboard requirements (see 5.2.3.3); --- Modify the original air tightness test and temperature test, the two combined test revised to check the air pressure through the inspection of a Test, because the original leak of gas leak detection inconvenience, learn from GB/T 21561.1-2008 application experience and pantograph gas-tight Sexual testing methods to change the test protocol (see 5.2.7.2.1, 5.2.5.2.1, 5.2.5.2.2 of IEC 62499-2008); --- Increase the wear test, with reference to TB/T 1842.3-2008 improve the pilot project (see 5.2.10); --- Remove the acceptance criteria of the test methods, the relevant content is the product standard range (see IEC 62499.2008 5.2.1.2, 5.2.2.2.2, 5.2.4.2.1, 5.2.4.2.3, 5.2.5.2.1, 5.2.5.2.2, 5.2.5.2.3, 5.2.5.2.4.2, 5.2.6.2, 5.2.7.2) . This standard also made the following editorial changes. --- Modify 5.2.3, 5.2.3.2 title and 5.2.3.1 Overview; --- Modify some references in the literature. This standard proposed by the National Railway Administration. This standard by the National Traction Electrical Equipment and Systems Standardization Technical Committee (SAC/TC278) centralized.
