摘　　要：基于目前特高压直流工程采取的双12脉动串联接线方式,分别计算了换流站相关位置使用ABB、西门子和中国西电集团西安西电避雷器有限责任公司三家不同避雷器时的操作过电压保护水平和避雷器耐受能量。通过比较三种避雷器下各点的绝缘水平,结果表明中国西电集团研制的避雷器性能与ABB和西门子公司的同类产品性能基本相同。Based on the double 12 pulse series-connection way of the current UHVDC project, the switching overvoltage protecting levels and arrester outstanding energies of three different types of arresters from ABB, Siemens and China XD （ China Xi＇an XD Arrester Co., Ltd ） at ±800 kV DC converter station are calculated. Comparing the insulation levels of the three types arresters, this paper concludes that the performance of surge arrester of China XD is basically the same as that of ABB and Siemens.
