摘　　要：提出用双层金属箔和双层绝缘层卷制而成的容性绕组取代铜导线绕组 ,通过改变变压器绕组结构 ,使其成为具有电容效应的电感线圈的基本思想 .给出容性绕组电力变压器的部分研制过程与检测结果 ,并对容性绕组分布电容特性、超前无功功率的产生、高功率因数的形成以及该变压器运行的基本原理加以论述 .This article gives a brief account of using double decker metal film and insulation film to roll into a kind of capacitive winding. Through the altering of the winding arrangement of the transformer, we can make it into an inductance coil with capacitive effect. The special points on the technology of this invention patent are clearly introduced in this article. A part of the procedure of the experiment as well as the result of the test can also be found here. At the same time, this article also gives an account on the specialty of the arrangement of capacitance of the capacitive winding, the leading reactive power, the formation of high power factor as well as the principle of the function of the transformer.
