标准摘要
[中文适用范围]： IEC 60099的本部分适用于不带火花隙的非线性金属氧化物电阻器型避雷器，设计用于限制两个端子@多端子和背靠背类型的HVDC换流站中的过电压，最高工作电压为1100千伏。该标准一般适用于瓷外壳和聚合物外壳型避雷器，也适用于仅用作直流母线和直流线路/电缆避雷器的气体绝缘金属封闭避雷器（GIS 避雷器）。电压源转换器的避雷器不包括在内。适用于换流站交流系统并承受 50 或 60 Hz 工频电压（主要不含谐波）的避雷器按照 IEC 60099-4 进行测试。交流滤波器上的避雷器根据此标准进行测试。 [外文原描述]： IEC 60099-9:2014 applies to non-linear metal-oxide resistor type surge arresters without spark gaps designed to limit overvoltages in HVDC converter stations of two terminal, multiterminal and back-to-back type up to and including an operating voltage of 1 100 kV. The standard applies in general to porcelain-housed and polymer-housed type arresters but also to gas-insulated metal enclosed arresters (GIS-arresters) solely used as d.c. bus and d.c. line/cable arresters. Arresters for voltage source converters are not covered. Arresters applied on the a.c. systems at the converter station and subjected to power-frequency voltage of 50 or 60 Hz principally without harmonics are tested as per IEC 60099-4. The arresters on a.c.-filters are tested according to this standard. Keywords: testing of gapless metal-oxide surge arrestors for HVDC converter stations
