摘要
由于机械式有触点分接开关不适合配电变压器使用,几乎所有的配电变压器都采用无载调压。本文介绍一种使用电力电子元件—固态继电器作为分接开关的在单片机控制下实现有载自动调压的配电变压器的基本结构,基本工作原理和设计方法以及实验结果。通过实验室模拟实验表面,采用固态继电器作为无触点分接开关可以实现快速频繁的有载调压,且具有谐波污染小,造价低的优点。
Because automatic-mechanic contact,tap-changing switch does not fit for distributing transformer,almost all distributing transformers adopt no-load voltage-regulating.This paper introduces a distributing transformer which uses power electronic component as tap-changing switch of the transformer and ealizes automatic on-load voltage-regulating under the control of single-chip.We present the structure,fundamental principle,design method of each link and experimental results of the distributing transformer.The results show that we adopt solid-state relay as non-contact tap-changing switch has merits that on-load voltage-regulating response quickly,small waveform distortion,long lifetime and low cost.
