1000 kV交流特高压避雷器和高压直流避雷器(±500、±660、±800 kV等)往往在结构上采用多柱并联(甚至多只并联)，以增强其能量吸收能力或降低残压。那么多柱并联避雷器的残压和电流分布应如何控制，才能通过型式试验和例行试验满足标准和技术协议的要求呢？针对目前认识误区，以1000 kV交流特高压避雷器为例，利用数学分析论证的方法，解剖多柱避雷器残压和电流分布的控制原理，并提出可应用于实际的控制建议，其结果可推广到相同结构的高压直流避雷器(或交直流避雷器的相关试验)之中。

1 000 kV AC ultra-high voltage arresters and high voltage DC arresters (±500, ±660, 800 kV, etc.) usually adopt the multi-column parallel-connected structure (even the multiple arresters parallel-connected structure), so as to enhance their energy absorbing capabilities or to reduce residual voltage. In that case, how to control over the residual voltage and the current distribution of the parallel-connected multi-column arresters in order to pass the routine test and meet requirements in standards and technology agreement? This paper points at misunderstandings of this field at present. Taking 1 000 kV AC ultra-high voltage arresters for example, and using mathematical analysis and demonstration method, the control principle for residual voltage and current distribution of multi-column arresters was analyzed. And practical suggestions for controlling were proposed. The results can be extended to high voltage DC arresters with the same structure (or to relative experiments on AC/DC arresters).
