【摘要】：简述了行业标准JB/T 10609-2006《交流三相组合式有串联间隙金属氧化物避雷器》应修订的各种原因。从避雷器的持续运行电压、避雷器的额定电压、避雷器的工频放电电压、避雷器的保护水平、避雷器动作负载试验、避雷器工频电压耐受时间特性试验、避雷器局部放电试验等几方面,论述了修订后的标准和JB/T 10609-2006标准的主要技术差异,并分析了典型避雷器的持续运行电压参数及20 k V系统电站用典型避雷器的电气性能参数选取时的考虑因数,同时,在修订的标准中提出了该参数的建议值。为便于修订和执行标准,结合相关资料,介绍了避雷器相-相间的工频放电电压试验方法和冲击放电电压试验方法。
[Abstract]:The reasons why the industry standard JB/T 10609-2006 "alternating current three-phase combined metal oxide arrester with series gap" should be revised are briefly described.From the continuous operation voltage of the arrester, the rated voltage of the arrester, the power frequency discharge voltage of the arrester, the protection level of the arrester, the load test of the arrester action, the test of the voltage tolerance time characteristic of the arrester's power frequency,The main technical differences between the revised standard and JB/T 10609-2006 standard are discussed.The continuous operation voltage parameter of typical arrester and the factor of considering the selection of electrical performance parameters of typical arrester for power station in 20kV system are analyzed. At the same time, the suggested value of this parameter is put forward in the revised standard.In order to revise and implement the standard, the test methods of power frequency discharge voltage and impulse discharge voltage between phases of arrester are introduced.
