Foreword
This standard was drafted according to GB/T 1.1-2009 given rules.
This standard replaces GB/T 8905-1996 "sulfur hexafluoride gas in electrical equipment management and inspection guidelines."
This standard compared with GB/T 8905-1996, mainly in the following differences.
--- Increasing the terms and definitions;
--- Increased the impact on the environment of sulfur hexafluoride;
--- Sulfur hexafluoride increased the impact on health and safety;
--- Increasing the re-use of sulfur hexafluoride quality norms;
--- Increased sulfur hexafluoride analysis methods;
--- Increasing the recycling of sulfur hexafluoride gas processing, storage and transport;
--- Added Appendix A, Appendix B, Appendix C and Appendix D four informative annex;
--- Remove the differential gas.
This standard uses redrafted modification method using IEC 60480.2004 "at detecting and removing from the electrical equipment of sulfur hexafluoride gas
Li Guidelines "(in English).
The Standard Appendix C lists a number of 60480 standard reg reg control list number IEC . Provision about the technical differences
And into the body of a single vertical line identifies them involved with the provisions margin. These technical differences are given in Appendix D
A list of its cause.
For IEC 60480 This standard also made the following editorial changes.
--- IEC 60480 will be changed to GB/T 8905;
--- Remove the IEC 60480 foreword and introduction;
--- The maximum permissible level of impurity gas recovery requirements change over test of time.
This standard is proposed and managed by the China Electricity Council.
