To confirm the running reliably and keep the advance of structure, the thesis starts from the basic principles, analyses the essence of kinds of breakdown, especially about the breakdown of oilpaper structure, and gives a detailed analysis using finite element method.

为了确保变压器的可靠运行，保持结构的先进性，本文先从基础理论出发，分析了各种击穿现象的本质，由此分析了变压器油—纸绝缘结构各组成部分的击穿情况，在此基础上提出了具体的有限元计算分析方法。

Its structure and property have not been understood clearly. Polyimide wear-out and breakdown can occur under long-term electric stressing due to many different reasons, making their insulating life ended. Wear-out and breakdown of polymers are closely related to the dissipation of electrostatic energy in space charge region.

聚合物的老化和击穿与空间电荷区域静电能的释放有关，电致发光代表材料中分子受激的化学活性强的状态，是能量耗散的方式之一，可作为材料预击穿及结构老化的先兆，是研究聚合物分子中的陷阱结构和它所控制的空间电荷的存贮和输运特性的重要实验手段。

Double series PIN diodes operates at a hold-off voltage of 4.2 kV, and the dV/dt is promoted from 1.7 kV/ns to 2.3 kV/ns.

对于这种特殊的硅二极管结构，在它上面加一个很快的冲击电压，当冲击电压高于二极管的直流击穿电压时，二极管不会立刻击穿，会有几 ns的延迟。

The influence of impulse voltage waveshape on particle-initiated breakdown voltage of a GIS system in SF6 and SF6/Air mixtures is reported. The results are compared with the characteristics of air gaps. For the SF6 gaps, breakdown voltage depends on wave-front duration but almost independs on wavetail duration. For the gaps in SF6/Air mixtures, the influence of impulse waveshape also depends on SF6 contents and electrical field non-uniformity

作者研究比较了正极性冲击电压波形对SF_6、空气、SF_6/空气的 GIS 电极装置由固定导电微粒引发的击穿电压的影响，结果表明：SF_6间隙的击穿电压受冲击电压波前时间长短的影响较大，而与波长的关系不大，当采用SF_6/空气混合气体时，则这种影响随SF_6含量增大而愈明显，并与电场不均匀程度有关。

The output and transfer characteristic have small change after soft breakdown as the degradations of drain current and threshold voltage is continuous.

在软击穿后，输出特性和转移特性只有小的改变。在软击穿发生时，漏端的电流和域值电压的退化是连续变化的。

The experimental result shows that when the discharge time was more than 1.5μs, small crack emerged in the fuses due to mechanical force on the heated fuse, and the metallized layer would be evaporated as the crack became long enough to generate disruptive discharge. When the discharge time was less than 150ns, small crack emerged in the fuses due to the current heat, and the metallized layer would be evaporated as the crack became long enough to generate disruptive discharge.

实验结果表明：当熔丝的通流时间大于1.5 ms时，电流热效应产生的机械力使安全膜熔丝的金属层产生微小裂纹，当裂纹达到一定长度，两端发生击穿放电，金属层因蒸发而断开；当熔丝中通过较大的电流时，短时间内(50 ns)的电流热效应使熔丝金属层发生熔化产生裂纹，裂纹两端发生击穿放电，金属层因蒸发而断开。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
