泄漏电流对温度的高低也有反映。温度越高、泄漏电流越大，相应的绝缘电阻也越小。固体材料的绝缘电阻随温度的增加而下降。

The leakage current also reflects the temperature. The higher the temperature, the greater the leakage current, the smaller the insulation resistance. The insulation resistance of solid materials decreases with the increase of temperature.

绝缘电阻（或介质电导）的数值与电压有关，通常在介质接近击穿时，有显著的、快速增加的自由电子导电现象，这时阻值将剧烈下降。

The value of insulation resistance (or dielectric conductivity) is related to the voltage. Generally, when the dielectric is close to breakdown, there is a significant and rapid increase of free electron conductivity, at this time, the resistance will drop sharply.

如下图所示为固体介质的典型电流一电压特性。其中可划分为三个阶段。在阶段a：电压与电流的关系服从欧姆定律；在阶段b：电流与电压 几乎成指数关系；在阶段c：电流将随电压急剧增加直至击穿。

As shown in the figure below, typical current voltage characteristics of solid media are shown. It can be divided into three stages. In stage a, the relationship between voltage and current obeys Ohm's law; in stage B, the relationship between current and voltage is almost exponential; in stage C, the current will increase sharply with voltage until breakdown.

当固体介质中存在杂质时，将使绝缘电阻下降，如水分的渗入使介质受潮等， 引起的绝缘电阻减小，绝缘强度降低。所以，带电作业工具防潮是一个不容忽视的问题。

When there are impurities in the solid medium, the insulation resistance will decrease. For example, the infiltration of moisture will dampen the medium, which will reduce the insulation resistance and the insulation strength. Therefore, the moisture-proof of live working tools is a problem that can not be ignored.

上面讨论的是固体介质内部的电阻（或电导）。实际上固体介质的表面因表面脏污和受潮还存在不小的表面电导。表面电导同脏污和受潮的程度成正比。所以带电作业工具表面应保持清洁，并且注意不能使之受潮。JXF电机引接线 电机引出线

What is discussed above is the resistance (or conductance) inside the solid medium. In fact, the surface conductance of solid media is not small due to surface contamination and moisture. The surface conductance is directly proportional to the degree of dirt and moisture. Therefore, the surface of live working tools should be kept clean and be careful not to damp them.
