Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB /Z 24846-2009 "1000kV AC electrical equipment preventive test procedures", and GB /Z 24846-2009
The main changes are as follows.
--- Added terminology and definitions "initial value difference" and "fixed series capacitor compensation device" (see 3.1.5 and 3.1.13);
--- Added the section "Fixed Series Capacitor Compensation Devices" (see Chapter 12);
---Modified "General" "Power Transformers and Reactors" "Switching Devices" "Insulators" "Insulating Oil and Sulfur Hexafluoride Gas" and "Metal
Test items, cycles and requirements for the section "Oxide arresters" (see Chapters 4, 5.1, 5.2, 5.3, 7.1, 9.2, Chapter 10 and
11.1, Chapters 4, 5.1, 5.2, 5.3, 7.1, 9.2, Chapter 10 and 11.1 of the.2009 edition;
--- Removed the "experience test method for gas-insulated metal-enclosed switchgear" (see Appendix C of the.2009 edition).
This standard was proposed by the China Electricity Council.
This standard is under the jurisdiction of the National UHV AC Transmission Standardization Technical Committee (SAC/TC569).
This standard was drafted. State Grid Corporation, China Electric Power Research Institute Co., Ltd., State Grid Operation Branch, State Grid Weibei Power
Institute of Research, State Grid Shanxi Electric Power Company, State Grid Henan Electric Power Company, State Grid Hubei Electric Power Co., Ltd., State Grid Shanghai Electric Power Corporation
Division, State Grid Fujian Electric Power Co., Ltd., State Grid Shandong Electric Power Company.
