产 品 说 明
1、无励磁调容分接开关
 

本开关是调容量变压器在无励磁条件下的分接调换装置,该分接开关适用于电压等级在10kV及以下,容量在315kVA及以下的三相油浸式调容变压器。可在无励磁的条件下对高压线圈作Y、D,低压线圈作串、并联切换,以变换变压器的容量,达到降低铁心损耗,提高变压器负载率因素,消除“大马拉小车”现象的目的,同时也可利用本开关调节电压分接头。

Off-circuit Capacity Regulating Tap Changer

This type of tap changer is designed as step changeable facility used for capacity regulating transformer under non-energized condition. It is suitable for three-phase oil-immersed capacity regulating with voltage rated 10kV and below, rated capacity 315kVA and below. It can be connected in series and parallel system on LV and HV windings or connected by star or delta method through which to realize transformer capacity changeable. By this way we can reduce iron loss and increase transformer load efficiency and power factor avoiding the phenomenon of “Big horse will drag small carriage”, And can be used to regulate voltage terminals.
