| 摘 要： | 随着科技和经济的发展,大量用电设备对供电质量的要求越来越高,传统的有载调压变压器由于其固有的缺陷而不能满足要求。现有的通过继电器切换或炭刷来调节电压的交流稳压器通常用在低压用户端,而且也存在一些弊端。目前正研究的无触点有载调压变压器,由于晶闸管是直接用于主电路,因此需要大量的晶闸管串并联,控制复杂,体积大,价格高,并且技术也未成熟,并没有推向市场。基于此,本文提出了一种配电系统的无触点有载调压拓扑结构,它具有上述装置的优点,同时又克服了其缺点。本文除了对其工作原理,主电路进行了介绍外,还重点对暂态无冲击控制条件进行了分析,最后通过实验对该设备进行了验证。

| Abstract: | With the development of the society and sharp increase of electricity consumption, the traditional on-load tap changers of the power transformer and the existing AC voltage regulators can not be satisfied by the requirements of power system, so a novel no-contact on-load voltage regulator topology is given in this paper. The principle and main circuit are introduced, the control condition of transient process is emphasis analyzed. Finally, experiment is given to confirm the above-mentioned claims. |
