| 摘 要： | 有载调压变压器能控制环网潮流及调整节点电压,但传统的有载调压开关在切换时产生的电弧可引发一系列不良后果,限制了它的应用.介绍一种自主开发的新型有载调压开关,利用电力电子器件--可控硅,并设计一套简单可靠的电子控制电路,消除了切换时的电弧现象,可把有载调压变压器的应用推向一个新阶段.

| Abstract: | On-load tap changer (OLTC) transformer can be used to control power flow in closed loop as well as to regulate bus voltages in power network. But the electric arc in commutating process that may lead to a series of harmful effects restricts its application. A brand new type of OLTC is introduced in this paper. By assistance of thyristor and a simple, reliable control circuit, the commutating arc is vanished at all. The new type of OLTC will push the application of OLTC transformer to a new stage. |
