摘要
传统的有载调压开关在切换时产生的电弧可能引发不良后果,采用反并联晶闸管作为分接开关,利用晶闸管过零点自然关断的特性,提出一种无弧切换的变压器调压模型。并且运用二进制编码调解法,对调压绕组进行编码以便于调压控制。
The arc of traditional on-load voltage regulatin switch may lead to harmful effects during change-over. In the paper,use an antiparallel thyristor as a tapping switch. By natural cut-off characteristic of the thyristor null-current,put forward a voltage-regulating model of non-arcing change-over of the transformer and use the binary coding to code the voltage-regulating windings,carrying out the voltage-regulating control.
