避雷器

Lightning arrestors, for instance, contain special materials that under normal conditions do not permit the flow of electrical current.

比如避雷器是含有特殊的材质的，正常情况下是绝缘的。

To deal with those added millions of volts, utilities rely on a complex array of lightning arrestors, static lines and grounding systems.

为了处理这些额外的百万伏特的电量，通常需要一组复杂的避雷器、静压操纵管路和导入地面系统。

"Lightning arrestors are not inexpensive devices and they must be maintained once they are put on the system," Hartlein said."You want to distribute them on the system frequently enough to protect it, but not so frequently that you are wasting money."

Hartlein说：&避雷器并不是廉价的装置，一旦被置入系统中后，就必须加以保养和维修，你想要频繁地在系统中使用它们，那就得好好保养它们，但也不用保养得太频繁，否则就是在浪费钱了。&

Without the arrestors, lightning could arc across the insulators that support power lines, causing interruptions and damaging other equipment.

如果没有避雷器，电弧能够通过那些包裹着电缆线的绝缘体，从而引发电力中断并损坏其他设备。

At NEETRAC's facilities near Atlanta's Hartsfield-Jackson International Airport, Hartlein and his research team evaluate the arrestors and help utilities choose the right locations for them.

在亚特兰大国际机场附近的国家电力能源测试研究与应用中心工厂内，Hartlein和他的研究小组鉴定了这些避雷器，并帮助公众选择正确的安装位置。

We calculate the lighting overvoltage of Ganzhou 500kV Substation by electromagnetic transient program. The results show that impulse-grounding resistance of towers before the Substation should be reduced to 7Ω and arrestors should be installed in two-group lines.

通过EMTP电磁暂态仿真程序对赣州500kV的雷电过电压水平进行了具体的计算分析，得出了该变电站终端塔接地电阻应减小至7Ω，并且两组母线均应装设避雷器的结论。
