Tesla变压器锥形绕组电压分布实验研究

Experimental Research on the Voltage Distribution of Taper Windings of Tesla Transformer

为了研究Tesla变压器锥形高压绕组的电压分布特性,通过模拟实验对Tesla变压器均匀密绕的锥形线圈进行了电压测量。测量结果表明,锥形线圈的电压分布不均匀,在100ns脉冲作用下,其匝间电压呈U型分布。在此基础上,通过对不同结构锥形线圈的电压测量及分析,提出了如增大绕组高、低压端线匝的间距及线径、在低压端增加短路环、线圈中增加均压环等改善其电压分布的措施,。

By use of the taper high voltage windings, the Tesla transformer with compact structure can be built. However, the flashover between coils will occur because of non-uniformity of the voltage distribution along the windings. In order to study the voltage distribution on the pulse transformer＇s taper windings, according to the structure of the factual pulse transformer＇s taper windings, the voltage of a uniform Tesla transformer＇s windings was measured by a simulation experiment. Results show that the voltage distribution of taper winding is not uniform, and the distributed curve of its interturn voltage is in U shape with 100ns pulse. Based on the results, by measuring and analyzing the voltage distribution of other taper windings with different structures, the methods to improve the distribution of the tape winding were put forwards, such as increasing the distance between the enameled wires on the high voltage section and grounding section, increasing the radius of the enameled wires on the high voltage section and grounding section, adding short rings on grounding section and adding grading rings.
