Summary This standard specifies the application and criteria for the validity extension of the type test of 3.6 kV~40.5 kV AC metal-enclosed switchgear and control equipment, as well as the general method for the validity extension of the type test. This standard applies to GB/T 3906-202. The specified rated voltage of 3.6 kV ~ 40.5 kV AC metal-enclosed switchgear and control equipment, and other equipment in the same enclosure that may affect each other. This standard applies to the validity of a type test to be carried out on one sample of a set of established ratings, extending to other switchgear assemblies of the same family having different ratings or different element arrangements. NOTE: For consistent compliance assessment and optimization of type testing, this standard supports the same family of switchgear and control

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard uses the redrafting method to modify and adopt IEC /T R62271-307..2015 "High Voltage Switchgear and Control Equipment Part 307 Points. Type test of AC metal enclosed and solid insulated enclosed switchgear and control equipment with rated voltage above 1kV and 52kV "Extended Validity Guidelines." Compared with IEC /T R62271-307..2015, this standard has structural adjustments. Change 1.1 of IEC /T R62271-307..2015 For "1 Scope", 1.2 was changed to "2 Normative Reference Documents", so that the subsequent article number was postponed. The technical differences between this standard and IEC /T R62271-307..2015 and the reasons are as follows. --- With regard to normative quotation documents, this standard has been adjusted with technical differences to suit China's technical conditions and adjustments The situation is reflected in Chapter 2 "Regulatory Reference Documents", with specific adjustments as follows. ● Replace IEC 60050-441. 1984 and IEC 60050- with GB/T 2900.20-2016 which adopts international standards 441. 1984/AMD1..2000; ● Replaced IEC 62271-200..2011 with GB/T 3906-2020, which was modified to adopt international standards; ● Replaced IEC 62271-1..2007 and IEC 62271-1 with GB/T 11022-2011 which adopts international standards. 2007/AMD1..2011; ● Deleted IEC 62271-201..2014. --- Deleted the solid insulated enclosed switchgear and control equipment that do not exist in China in Chapter 5 of IEC /T R62271-307..2015 Related extensions. --- Deleted the extension criterion for the cross-sectional area of conductors in Article 5 of Table 7 of IEC /T R62271-307..2015. This standard has made the following editorial changes. --- To be consistent with China's technical standard system, the standard name was changed to "3.6kV ~ 40.5kV AC metal-enclosed switchgear and control "Guidelines for the Validation of Type Testing of Manufacturing Equipment"; --- Adjust references.
