特斯拉环-人造闪电.doc

Small Tesla Coil 微型特斯拉线圈制作 This is my first Tesla coil. It was inspired by an article in the March 1995 issue of Electronics World Wireless World. Construction was much more straightforward（简单直接的） than I expected. I am now tempted to build a bigger one. This is not intended to be instructions for building a Tesla coil, just documenting what I built. 这是我的第一个特斯拉环。其灵感来源于Electronics World Wireless World 1995年三月刊登的一篇文章。制作方法比我预想的更简单直接。我现在打算做一个更大的。并不打算把这篇文章作为制作特斯拉环的说明书，仅仅是为了记录我所做的东西。 Circuit Description（电路说明） The Tesla coil consists of a primary resonant circuit（谐振电路） (C1 and L3) and a secondary resonant circuit (L4 with self capacitance（电容） and terminal（端的） capacitance). The primary and secondary resonant frequencies must match. The mains transformer (T1) charges the primary capacitor（电容器） (C1) until the spark gap (GAP1) fires. When this happens, the stored energy is applied to the primary coil (L3). There is loose coupling（连结） between L3 and L4, causing a very high voltage（电压） to develop across the secondary. The series chokes (L1 and L2) are to prevent RF（射频） energy passing back into the mains transformer (T1). 这个特斯拉环由初级谐振电路（C1和L3）和次级谐振电路（有自身固有电容的L4和末端电容器）两部分组成。初级、次级两部分的谐振频率必须相吻合。电源变压器为初级电容器一直充电到火花放电器尖端放电为止。当火花放出时，存储的能量就会被输入进初级线圈（L3）。L3和L4间弱耦合，使得次级谐振电路中生成一个极高的电压。串联扼流圈（L1和L2）用来防止射频能量返回电源变压器。 Construction（制作过程） It is difficult to predict with reasonable accuracy（准确性） what the resonant frequency of the secondary will be as it depends upon its self capacitance. I found it easiest to build the secondary first, measure its resonant frequency and then design the primary circuit to match. The secondary was wound（缠绕的） by hand on a 200mm length of 40mm diameter（直径） drain pipe（排水管） using 0.26mm diameter enameled copper wire（漆包线）. Double sided tape（双面胶带） was used to prevent the windings（线圈） from unraveling（散开） during construction. The top electrode（电极） was made from a glass flask（玻璃长颈瓶）, inverted（翻转的） and coated （涂上一层的）with conductive paint（导电涂料）. The coil was varnished（漆过的） in
