With the exception of the triggered static gap, most static gaps fire naturally due to overvoltage breakdown. 除了引发了静态差距,大多数静态差距自然火因过电压故障。The picture on the left shows a multiple static spark gap, made up of several smaller spark gaps connected in series. 这幅画在左边显示出多个静态火花隙,由几个小火花间隙连接在系列。The multiple gap is constructed from several parallel copper tube sections, with 0.5mm air gaps between them. 构建而成的多重差距几个平行铜管部分,气隙0.5他们之间。The electrodes are mounted on a central plastic tube, and are surrounded by another plastic tube at the outside. 电极安装在中央塑料管道,周围的另一个塑料管道在外面。Fans are fitted at both ends of the enclosure to provide a high flow rate of fresh air during operation. 球迷安装附件的两端提供一个大流量的新鲜空气,在操作期间。This cools the electrodes and removes hot ionised gases from the spark gaps, improving performance considerably.这个冷却电极和消除热气体ionised火花间隙,大大提高绩效。

The required breakdown voltage is selected by "tapping" at the appropriate number of gap sections. 所需的击穿电压被“开发“在适当数量的差距的部分。More gaps in series gives a higher breakdown voltage.更多的缺口击穿电压给予较高的系列。
This spark gap is often incorrectly referred to as an RQ-gap but was originally developed by the Tesla Coil builders of Richmond group. 这火花隙通常被今人称一个RQ-gap但最初是由特士拉线圈建设者里士满的组。It performs well up to power levels of around 2kW. 它表现出色,采用左右的功率电平。Above this level cooling and electrode erosion become problematic.这个区位以上冷却和电极侵蚀成为问题。

 Toroid,Toroid,

The metal toroid of a Tesla coil system sits on top of the secondary coil and provides the last point from which the electricity "jumps-off" into the air.金属toroid特士拉线圈的坐在上面的系统,并提供第二组线圈的最后一点jumps-off电”的“到空中。
This shape is often formed by bending ventilation ducting into a circle, however a more professional appearance can be achieved by using metal spinning techniques on a lathe.这种形状已经经常形成了通风管道的受力成一圆,不过更专业的外观可以达到使用金属纺纱技术对车床。
|
A correctly sized and positioned toroid provides several useful functions:一个正确的大小和位置toroid提供几个有用的功能:
-
The toroid adds capacitance to the "open end" of the secondary coil.toroid增加电容的“开放的结束”的二次线圈。
Without a toroid, the resonant frequency of the secondary is dictated by the self capacitance of the winding and stray capacitance to the surroundings. 没有toroid,谐振频率的二次体制是由自已电容的线圈绕组和对环境的寄生电容。This makes the resonant frequency quite high, and somewhat sensitive to detuning. 这使得谐振频率相当高,有些敏感的失谐。When a toroid is added to the top of the secondary, its capacitance adds to the self-capacitance of the winding. 当一个toroid被加在整个建筑的顶部的二次,其电容增加self-capacitance沿弯曲的。This lowers the resonant frequency of the secondary. 这样可以降低谐振频率的次要的。I also believe that the capacitance of a large toroid swamps streamer capacitance, and therefore reduces the detuning effect that long sparks have on the secondary frequency.我也相信,容量大toroid沼泽晕船,因此减少电容失谐效应有二次长火花频率。
-
The toroid provides electrostatic shielding of the top turns of the secondary winding.toroid提供的静电屏蔽的顶级二次绕组的转向。
The toroid is electrically connected to the top turn of the secondary coil, and its presence directly above the secondary reduces the electric field stress on the top winding. 这toroid是电连接到最高的转动,第二组线圈它的存在直接在上面的电场二次减少压力放在最上面的绕组。Without a toroid, a large E-field gradient would exist between the top turn of the secondary and the surrounding air. 没有toroid、大量存在梯度加总之间最高化的第二、周围的空气中。By surrounding the top turn of the coil by a large metal terminal at the same potential, this field gradient is removed, reducing the tendency for sparks to be emitted from the top of the secondary winding.前通过围满了线圈被大金属终端梯度,这个领域相同电位被移走,降低的趋势是发出火花,二次绕组的顶端。
-
The toroid provides a local store of charge to fuel spark propagation.toroid提供了一个当地的商店的燃料向火花繁殖。
Once the air surrounding the toroid has broken down it requires charge to drive the streamers out to great length. 一旦周围的空气中的toroid拆毁了它需要费用,把饰带的成绩。Since the secondary is highly inductive, it does not represent an instantaneous source of current to any arcs emitted from the top. 自从二次非常有感结构,并不代表电流的即刻的来源发射任何电弧顶部。Even the self-capacitance of the secondary is distributed, so only a limited amount of this stored energy is available to feed sparks. 甚至self-capacitance二次分布,所以只有有限的几条这存储能量是提供给饲料的火花。The addition of a large toroid provides local energy storage at the top of the secondary. 增加了一个大toroid提供当地储能在顶部的次要的。The capacitance of the toroid should swamp the distributed capacitance of the secondary so that most of the energy is stored in the terminal capacity and little is trapped in the distributed capacitance of the resonator. toroid的电容的分布电容应该沼泽的第二位的,大部份的能量储存在终端能力和小被困在分布电容的谐振器。Arcs to ground are visibly more intense when a large toroid is used to provide considerable terminal capacity.弧去地明显更强烈当大量的toroid是用来提供重要终端能力。
-
The toroid forms a smooth surface to delay the onset of air breakdown.toroid表面光滑的形式对延缓疾病发作的空气故障。
Without a toroid, the air surrounding the top of the secondary coil would breakdown at a fairly low voltage due to its sharp radius of curvature. 没有toroid,周围的空气中的上面的第二组线圈故障会以一个相当低电压由于其锋利的曲率半径的。This would result is fairly short sparks being emitted before the full potential was reached. 这将结果是相当短的火花完整的潜能之前被发出的决赛。When a toroid is fitted, the high radius of curvature allows the terminal to reach its maximum potential before the surrounding air breaks down. 当一个toroid安装,高曲率半径的允许终端及其周围的空气前最大的潜力被破坏。This ensures maximum charge on the toroid before the spark begins to propagate from its surface.这保证了toroid最大上电荷的火花开始繁殖之前从它的表面上。
The effectiveness of a given toroid depends on the system in which it is operated. 一个给定的toroid的有效性取决于所在的系统中操作。Generally, small toroids with rough surfaces produce many short arcs. 一般来说,小toroids与粗糙表面产生许多短弧。In contrast toroids which are physically large and have a very smooth finish perform better by forming only one longer arc.相比之下toroids这身体上大,并已非常光滑表面表现得通过形成只有一个再电弧。
The overall size of the toroid (major dimension) determines the capacitance of the terminal. 总体规模toroid(最大尺寸)决定了电容内的终端。The larger the toroid, the more capacitance it has, enabling it to store more energy. toroid越大,越电容,使他能够储存更多的能量。However, remember that the peak voltage actually decreases as the toroid is made bigger !然而,要记住峰值电压实际上降低的toroid是作了较大的!
The thickness of the toroid (minor dimension) determines the radius of curvature. toroid的厚度(小尺寸曲率半径)决定了。It is this dimension that influences the voltage at which the toroid will breakout. 这是这方面影响了电压的toroid将突破。Fat toroids have a higher radius of curvature, and require a high voltage to cause break out, whereas a thin toroid will break out at a much reduced voltage.脂肪toroids曲率半径有更高,并要求高压引起打破出来的,而薄toroid将爆发在更低的电压。
It is easily possible to make a toroid so large and smooth that spark breakout is suppressed completely. 它很容易可以做toroid这么大,光滑,完全被压制火花突破。In this case, a "breakout point" can be placed on the surface of the toroid to produce a localised field stress and promote breakout in that region. 在这种情况下,“突破上可放置点”的表面产生一种局部的领域toroid压力,提高分组在那地。I have found this approach successful in producing the longest arc possible from a given power.我发现这个方法成功地生产最长的弧可能从一个给定的力量。
Three toroids were stacked on top of each other in the picture above. 三toroids被上下堆叠在上面那张图片一样。This was done to add considerable capacitance to the secondary and drop its resonant frequency to a low value. 这样做,以增添了相当大的电容次并降低其共振频率低价值。This in turn allows a large primary capacitor to be used to maximise power delivered to the primary. 这反之允许一个大主要电容器被用来使电力送到小学。From this explanation it can be seen that the choice of toroid is very important, and can influence other aspects of the design right back to the primary capacitor and even the power source !从这个解释可以看出,toroid的选择是非常重要的,可以影响其他方面之设计对回到源电容,甚至电源!
There is considerable discussion on the subject of "correct toroid sizing" in the有较大的讨论了这个问题的“正确”toroid上浆Pupman Tesla list archivesPupman特士拉列表档案.
Primary Coil,初级线圈,

The primary coil and primary capacitor form the primary tank circuit. 初级线圈和主要的电容形成主要坦克电路。This parallel resonant circuit is responsible for the generation of RF oscillations in the Tesla Coil system every time the spark gap fires.这平行负责谐振电路产生的射频振荡特士拉线圈系统每次星火的差距,火灾。
The primary coil pictured opposite is an inclined spiral wound from 1/4" (6.4mm) soft copper tubing. 雕刻的相反的主要线圈缠绕不想从1 / 4 "(6.4毫米可供选择的软性铜管。The most effective number of turns, spacing and geometry are dependant on the design of the overall system.最有效的圈数、间距和几何可以依靠整个系统的设计思路。
In particular the resonant frequency and Q of the primary tank circuit are influenced by the construction of the primary coil.特别是谐振频率和问最主要的坦克电路的建设影响的主要线圈。
|
There are several aspects of the primary coil worth consideration at the design stage:有几个方面的初级线圈值得去考虑,在设计阶段:
- High current capability,高电流能力,
The peak currents in the primary circuit are tremendous when the spark gap fires and the tank capacitor is discharged into the primary coil. 峰值电流的主要电路的巨大火花隙火灾和坦克的电容器是排入主要线圈。In a small TC the peak primary current may be around 100A, and in a large system the peak current may be several thousands of amps ! 在一个小TC峰初级电流是在100A,在一个大系统的峰值电流可能有成千上万的放大器!The actual peak current is dependant on the primary voltage and surge impedance of the primary circuit, (see below.)实际峰值电流是依赖于初级电压及喘振阻抗的主要电路、(见下文)。
The high peak current means that the primary coil should be constructed from a good electrical conductor with low resistivity and considerable cross-sectional area. 高的峰值电流意味着初级线圈应该用良好的电导体与低电阻率和可观的横截面积。This keeps resistance low and minimises I²R losses.这使我的互信²低、电阻R损失。
- Skin effect,皮肤效果,
Skin effect discourages AC currents from flowing deep inside good conductors. 阻碍集肤效应交流电流流入内心深处良导体。This means that if you use a good conductor for your primary, then the heavy primary currents are forced to flow in a thinner layer nearer the surface of the conductor. 这意味着如果你使用你小学良导体,然后是厚厚的主要电流是被迫流动更薄层表面的指挥。The bulk of the conductor contributes little to AC conduction, but does help in the conduction of heat. 大量的导体小AC传导贡献却帮助传导热量。For these reasons, copper tube is a popular choice for primary coils. 由于这些原因,铜管是一种受欢迎的选择,并为初级线圈。It represents a good compromise between conductivity and ease of forming into the desired shape.它代表了一个好的妥协的传导性和便于形成送到所需的形状。
- Adjustable inductance,可调电感,
For a Tesla Coil to operate correctly the primary and secondary circuits need to be tuned to the same resonant frequency. 为特士拉线圈操作正确的初级和中级电路需要调到相同的共振频率。This can be achieved by making one component of either the primary or the secondary circuit adjustable. 制造的方法就可达此目的的组成部分之一或小学或二次回路可调。In a TC the resonant frequency of the secondary is usually "fixed" at the design stage, therefore the primary frequency must be made adjustable to allow accurate tuning. 在TC谐振频率的二次通常是“固定”在设计阶段,因此必须一次调频调整允许准确的调谐。The simplest way to achieve this is by making the primary inductance adjustable by means of a moveable tap point. 最简单的方法去达到这个是使初级电感可调,通过一个移动水龙头点。This allows the required number of primary turns to be selected to get the desired resonant frequency.这允许所需数量的初级圈是选择去获得预想共振频率。
Fp = 1 / [2 pi sqrt (Lp Cp)]成品= 1 /[2 pi sqrt(Lp Cp)]
The moveable tap connection should consist of a clamp with considerable force and surface area in contact with the primary winding to minimise resistance in light of the high currents mentioned above.水龙头动产连接必须由一个夹在相当大的力量和表面接触的初级绕组减少阻力根据上述高电流。
- Loose coupling to the secondary,松耦合到辅助,
For correct energy transfer in a two coil system the magnetic coupling between the primary coil and the secondary coil is fairly low or "loose". 用正确的能量传递在双线圈系统的磁性联结主要矛盾线圈是很低的第二组线圈或“松散”。(k<0.2) (k < 0.2)The exact coupling factor depends on the system, but can be heavily influenced at the design stage. 确切的光纤耦合系数取决于系统,但可能被严重影响在设计阶段。For example, a vertical helix primary which covers a considerable part of the secondary will give a very high coupling factor, whereas a flat spiral at the base of the secondary gives a comparatively low coupling factor.例如,一个垂直螺旋主要包括的相当一部分二次将给一个很高的光纤耦合系数,而扁螺旋在该基地的二次给一个比较低的光纤耦合系数。
After the design stage, the coupling factor can be adjusted slightly by altering the relative positioning of the primary and secondary coils. 在对设计阶段,光纤耦合系数可以通过改变轻微的调整的相对定位的小学和中学线圈。Raising the primary coil relative to the secondary will increase k, whereas lowering the primary coil causes a small decrease in coupling. 提高相对次要初级线圈将增加凯西,而降低初级线圈造成小降低耦合。Coupling factor is explained in more detail in the section on介绍了光纤耦合系数更详细的部分Tesla Coil operation特士拉线圈操作.
- High voltage clearance,高电压的间隙,
There are three clearance issues to consider with the primary winding. 有三个间隙,考虑的问题与初级绕组。Firstly, the primary winding must be able to withstand the peak primary voltage across the number of turns which are utilised. 首先,初级绕组必须能够承受主要峰值电压是立即的圈数。Peak primary voltages may be quite high, but are usually applied over several turns of the primary coil. 基本电压峰值可能相当高,但通常是在几个转应用的主要线圈。This means that the voltage difference between adjacent turns is quite low. 这意味着之间的电压差相邻转很低。Many turns can be packed into a small space to get maximum inductance with minimum length of conductor. 多次转变可以挤进一个小空间即可获得最大限度的电感与最低的长度为主体。The exception to this would be a very high primary voltage applied across a small number of closely spaced turns. 也有例外,这可能是一个非常高初级电压在少量排列紧密的回合。This situation may require attention to be given to inter-turn insulation.这种情况可能需要注意介绍inter-turn绝缘材料。
Secondly, there is autotransformer action in the primary winding as the primary tap point is moved to select the required inductance. 其次,这里有autotransformer绕组行动为主要挖掘的观点是搬到选择所需的电感。For this reason, the fixed connection is usually made to the innermost end of the primary coil, and the adjustable tap is located near to the outermost end. 因为这个原因,固定连接通常是由内心的结束,而调节线圈,主要是开发最外层临近结束。Care should be exercised when utilising few turns of a multi-turn primary, as autotransformer action can result in considerable voltage at the "open-end" of the primary. 你应该要小心使用时的转向行使多一些,因为autotransformer主要行动可以导致严重的电压在“开放式”的初选。This is likely to flash over to any nearby metalwork, such as a strike rail.这可能是附近任何flash在金属,如罢工的轨道。
Thirdly, there is clearance between the primary coil and the discharge toroid on top of the secondary. 第三,主要间隙放电线圈toroid顶部的次要的。The relative positioning of the primary and secondary coils is dictated by the coupling requirement mentioned above. 相对定位的小学和中学线圈的耦合取决于上述要求。For this reason the clearance from primary to toroid is mainly dependant on the length of the secondary coil and should be influenced by the anticipated spark length.因为这个原因清除小学至toroid主要依赖于在第二组线圈的长度,应受预期的火花的长度。
- Surge impedance,增兵阻抗,
From the equation in section 3 above, it can be seen that a particular resonant frequency can be achieved with many different combinations of Lp and Cp. 利用该方程可以由在第三节以上,可以看出,一个特定的谐振频率,才能实现与许多不同的组合,Lp及现行Cp。However, the inductance of the primary winding not only influences the resonant frequency of the primary, but also affects a property called surge impedance. 然而,电感的初级绕组不仅影响的主要的共振频率,同时也影响着财产称为增兵阻抗。Surge impedance is a parameter used to determine the response of an LC circuit to step changes in the circuit. 增兵阻抗是用于确定参数的反应跳变LC电路的电路。It is particularly useful in predicting the peak current which occurs in the primary circuit when the spark gap fires.它是特别有用的峰值电流预测的主要发生在电路星火的差距,火灾。
It is fairly intuitive that using a single turn primary winding would give rise to higher peak currents than using a multi-turn primary, but the degree of this affect is not immediately obvious.这是很直观,使用单把初级绕组导致更高比使用多峰值电流主要,但程度的这个影响不是立即显现。
The primary surge impedance is related to the primary capacitor and the primary inductor by the following equation:有关的主要增兵阻抗的主要电容和电感主要由以下公式:
Zp = sqrt (Lp / Cp)Zp = sqrt(Lp / Cp)
Zp represents the effective impedance of the LC circuit to the flow of current when the spark gap fires and the capacitor dumps its charge into the primary winding. Zp代表有效LC电路阻抗电流的流动的火花隙火灾和电容器将其收费进入初级绕组。The peak primary current can be found by dividing the "fully charged" capacitor voltage by the surge impedance. 峰初级电流,可以发现通过把“完全指控“电容电压的增兵计划阻抗。This gives an indication of the peak current that the spark gap and primary components will be subjected to:这给了一个估计的峰值电流的火花隙和主要部件会受到:
Ipk = Vp / ZpIpk = Vp / Zp
It can be seen that a specific resonant frequency can be achieved by keeping the product Lp Cp constant, but the surge impedance can be altered independently by changing the ratio of Lp / Cp.可以看出,一个特定的谐振频率,才能实现由保持不变,Cp产品Lp但是这个增兵计划阻抗通过改变可以改变的比率独立唱片/ Cp。
For example, doubling Lp and halving Cp in a given system, would leave the resonant frequency unchanged, but would double the surge impedance of the primary system. 例如,扩大和减少一半的脑瘫Lp在一个特定的系统,将会使谐振频率不变,但是会增加一倍的激增阻抗最主要的系统。The result is a 50% reduction is the primary current which flows through the spark gap. 结果是减少50%是初级电流流过火花隙。Since the gap represents a constant voltage drop, this implies a 50% reduction in power dissipation in the spark gap.自从差距不断的电压降的代表,这就意味着的功耗减少50%的火花隙。
In general primary surge impedance should be high (several tens of ohms) when compared to the resistance of the spark gap during conduction. 一般来说主要增兵阻抗应是高(数十欧姆电阻)相比的火花间隙在办理。This ensures that the majority of the energy from the tank capacitor is processed through the primary tank circuit, and minimal energy is "burned-up" in the spark gap. 这保证了大部分的能量从坦克的电容器是加工通过初步的坦克的赛道,能量最小”是“burned-up火花隙。Ultimately, there is a tradeoff against output voltage if too many primary turns are used.最后,有一个交易对输出电压初级圈如果过多的使用。

The picture opposite shows a 240V 15A variac for use with a 50Hz supply. 这张照片显示出240 variac 15A相反,为用的供应。The output voltage is variable from 0 to 275 volts.输出的电压是可变的从0到275伏特。
A variac is very useful in a Tesla Coil system because it allows the user to vary the supply voltage manually and therefore control the power level. 一个variac是非常有用的,在特士拉线圈系统,因为它允许用户手动电源电压改变,因此控制的功率水平。During initial testing the power level can be increased slowly whilst looking for any abnormal behaviour.在最初的测试的能量水平可以增加缓慢而寻找任何不正常的行为。
Due to the large thermal mass of the iron core and windings, variacs generally tolerate moderate overloads well. 由于大热大规模的铁芯绕组,通常variacs容忍适度过载。Twice the rated current for a couple of minutes presents no problem provided that the device is allowed to cool before it is operated again.两倍额定电流了好几分钟没有问题所提供的设备是让其冷却操作前了。
