变压器有载分接开关浅析

Initial analysis on on-load tap-changer of transformer

有载分接开关是变压器有载调压的主要装置。在变压器带负荷的状态下,有载分接开关改变高低压线圈之间的匝数比,从而达到稳定或调节负荷中心的电压,提高系统功率因数,减少无功损耗的目的。本研究介绍了有载分接开关的原理,并提出了运行维护中的注意事项。

On-load tap-changer is the main device of the transformer. In the transformer with a load state,the on-load tapchanger was changed between high and low voltage,so as to achieve stable or adjustable load center voltage,improve system and reduce reactive loss of effective measures. This paper introduced the principle of the on-load tap-changer,and put forward some matters needing attention in operation and maintenance。
