基于导体系统电容对变压器电容的研究

Research the Distribution Capacity of the Transformer Based on the Systematic Capacity of Conductor

电容器是一种常用的电子元件,不管是独立导体,还是多个导体组成的系统,都可构成电容器,对于多个导体组成的系统来说,它们所构成的电容可分为自部分电容和互部分电容,这些电容在有的电路中可以看成是分布电容。变压器是一个多导体系统特例,它是由铁芯(磁芯)、绕组、屏蔽层(接地)等导体构成,该系统所形成的分布电容对有的电路影响非常大,因此为了讨论该问题,本文从导体系统电容出发,系统地阐述变压器分布电容的形成、危害及克服办法。

The capacitor is a kind of electronic element in common use, Both independent conductor and the system which is make up many conductors can consist of capacitor,As far as the which is make up of many conductor can be divided into self-partile capacity and each other capacity, These capacity can be regarded as distribution capacity in some circuit . Transformer is a special case of multi-conductor systematic which is formed by iron core （magnetism core ） , winding , shielding layer （grounding） and so on..The distribution capacity is formed by this system which makes an adverse effect on som circuit .So in order to discuss this ques- tion,this text proceeds from systematic capacity of conductor, Systematically.elaborate the forming of the distribution capacity,the harm of the the distribution capacity,and the way to overcome.
