变压器无弧有载分接开关的研究

Study of Arcless On-Load Tap Switch for Transformer

为使开关的切换容量不断提高,灭弧方式更加完善,在对国内外无弧有载调压技术广泛调研和认真分析总结的基础上,提出了以电力电子开关为关键部件的无弧有载调压的技术方案。方案中用于有载调压的分接开关具有安全、可靠、便于维护等特点,且不会产生需要特殊处理的废料,主要用于容量较小的、直接向低压负载供电的降压变压器。

In order to make shift capacity raised continuously and more completed in are extinction method, based on serious analysis and summary and wide investigations for artless on-load voltage regulation technology both at home and abroad, technical plan with power electronic switch was raised as the key part of arcless on-load voltage regulation. In the plan the tap switch used for on-load voltage regulation is safe, reliable and easy for maintenance etc. and also no wastes to be specially disposed, it is mainly used for small-capacity step-down transformer directly to provide power supply to low-voltage load.
