串级变压器在照明节电中的应用

针对普遍存在的电力照明浪费现状,探讨并验证了一种节电降耗的思路,分析说明了采用补偿变压器串联在电网中的节电原理,进行了利用自耦调压器与串级变压器组成的调压电路的节电试验方案。结果表明,在以日光灯为负载的照明电路中,当电网电压超过日光灯额定电压时,只会造成超额电压部分的无效功耗,并不增加照度;而在电网中采用小功率的串联变压器时,能够调节稳定大功率的照明负载电压,从而达到节电降耗的目的。

Applications of series transformer illuminant energy saving

In order to reduce the electric cost,the theory of station series transformer in the grid was proposed to save electric energy,and the voltage-adjusting circuit consisting of self-coupling and series transformer was tested.The illuminance degree in the illuminant circuit is not raised when the voltage is higher than the limited voltage of fluorescent lamp,which leads to the ineffective power of the extra voltage.However,the setting series transformer can load high power so as to reduce energy cost.
