摘要: 高压输电线路通常采用线路避雷器并联绝缘子的方式作为其防雷措施,从而保证绝缘子在雷电时免受过电压闪络损伤,而此方式却造成线路和铁塔的负荷增大,线路设施复杂化。针对上述问题设计了一种具有绝缘子性能的避雷器,结合绝缘子和避雷器的试验标准以及设备的结构特点进行了试验研究和测试,并给出明确的试验项目和测试结果。

Abstract: In high voltage transmission line, insulators are usually placed in parallel with inline lightning arrester as lightning protection measures. This method can protect insulator from the overvoltage flashover when lightning. However, it tends to increase line load and equipment complexity. A new design of surge arrestor with insulator performance is proposed. The analysis and test is performed according to structural characteristics and test standard of both insulators and surge arresters. The test procedure and results are discussed in detail.

Key words: composite insulator, arrester with gaps, field strength computation, mechanical stress, electrical test, structural design, lightning protection
