Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB /Z 24839-2009 "Technical Specifications for Post Insulators for 1000kV AC Systems". Compared with GB /Z 24839-2009, the main technical changes of this standard are as follows. --- Increased the technical requirements for the pillar insulators for the series compensation platform (see 5.2.3); --- Increased the terminology, definitions and technical requirements for factory composite post insulators (see 3.2, Chapter 7). 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 is mainly drafted by. State Grid Corporation, China Electric Power Research Institute Co., Ltd. Participated in the drafting of this standard. Xi'an High Voltage Electric Apparatus Research Institute Co., Ltd., Fushun Electric Porcelain Manufacturing Co., Ltd., Hebei Silicon Valley Chemical Co., Ltd. Co., Ltd., Shandong Bianan Power Technology Co., Ltd. The main drafters of this standard. Wu Guangya, Sun Gang, Zhang Rui, Wang Ninghua, Qiu Ning, Li Qingfeng, Wang Xi, Chen Guoqiang, Ji Fang, Deng Tao, Dang Zhenping, Tang Xiaozhong, Song Furu, Luo Rong. The previous versions of the standards replaced by this standard are. ---GB /Z 24839-2009. Technical specification for post insulators for 1000kV AC systems

1 Scope

This standard specifies the general conditions of use, technical requirements, inspection rules, packaging, marking and transportation of 1000kV post insulators. This standard applies to porcelain post insulators used in 1000kV busbars, isolating switches, reactors, series compensation platforms, etc. The factory composite pillar insulator and solid core composite pillar insulator (hereinafter referred to as "insulator"). Pillar insulators for DC systems are also available use. This standard does not include some of the requirements involved in selecting post insulators for specific operating conditions.
