    摘 要:近区故障开断特性是断路器型式试验中的重要考核项目。就模拟一段架空线路的人工数学链路进行了研究及设计,介绍了人工数学链路设计及选型,对链路结构设计进行了阐述,并从人工数学链路的原理结构、参数计算、元器件选型以及过电压分析等方面进行了仿真计算,最终设计出了满足800 kV/63 kA整极、1 200 kV/80 kA半极近区故障试验要求的人工数学链路,并且与实际架空线路有较好的等价性。

    Abstract: The close-in fault making and breaking characteristic is the important evaluation indicator in circuit breaker type tests. A length of overhead line of artificial mathematics link was simulated to carry out research and design. Introduction was made to the artificial mathematics link design and selection. This paper expounded the link structure design and carried out simulated calculation from the aspects of principle structure of artificial mathematics link, parameter calculation, components selection and overvoltage, and designed the artificial mathematics link meeting the requirement of 800 kV/63 kA whole polarity, 1 200 kV/80 kA half polarity close-in fault tests, closely equivalent to the practical overhead line.
    Key words: close-in fault; artificial mathematics link; synthetic test; components selection; overvoltage analysis
