摘要
分析了变压器能耗产生的原因及节电途径,针对变压器在低功率因数情况下的严重浪费电能现象,提出一种自动节能装置并介绍了该节能装置的组成与工作原理。该装置可以随电网负荷变化引起的功率因数变化而自动控制,使功率因数保持在某一设定的较高合理水平,可广泛用于各种需提高功率因数的电网。
This paper analyzes the reason of power loss in transformer and the way of electric power saving. According to the phenomenon of seriously wasted electric power energy of transformer under low-power-factor circumstance, we study a kind of an auto power saving facility and introduce the constitution and work principle of it. This scheme achieves auto-controlling the power factor to follow the changed electric loading. It can hold the setting value of the power factor on a higher reasonable level. Generally, it also can be widely used to the electric power which need to heightened the power factor.
