摘要
常见的工频耐压设备大致可分为两类 :传统的升压变压器系统和串联谐振系统。本文比较了这两类设备使用特点 ,主要介绍了串联谐振系统工频耐压设备原理、结构和使用特点。提出了该系统对高电压、大截面和大长度电缆的进行工频耐压试验与传统的升压器试验系统相比 ,具有众多的优点。
The common commerical frequency voltage test apparatus are divided into two categories, namely the traditional step up transformer system and series resonance system. This peper presents the features of the two kinds of test apparatus, focusing on the work principle, construction and characteristics of the series resonance system. It indicates that compared to the traditional step up transformer system, the series resonance system has a lot of advantages for the commercial frequency voltage test of high voltage, large size and large length power cables.
