发贴心情  『原创』请教各位电气专业英语高手
我电气专业英语差,所以请教各位电气专业英语高手,能帮忙翻译一下以下否,在下将感激不尽,在此先行谢过。

要翻译的内容如下:



在我国6~35KV电力系统多采用小电流接地系统运行方式。单相接地故障是小电流接地系统发生几率最高的故障类型,约占所有故障次数的80%。虽然规程规定单相接地故障发生后配电网可继续运行2h,但由于单相接地故障可能会进一步发展为两点或多点故障,从而引起跳闸停电事故,因此及时确定故障位置并排除故障便显得非常重要。为了避免故障的发生或故障后尽快消除隐患,本文就小电流接地系统单相接地故障进行了深入的分析与论述。首先对各类型中性点接地方式的划分及其特点进行分析,从而根据单相接地故障时故障相和非故障相的电压、电流变化特性,设计了系统绝缘监视装置,根据各相对地电压的特征判别出接地故障的类型和故障相。此外还对消弧线圈熄弧原理和补偿电网的作用机理进行了说明。由于传统的逐线拉路方法严重影响了供电可*性,人们研究提出了多种选线方案,这里一一列出,并全面地对这十余种故障选线方案的原理进行简介并比较分析其利弊。最后,为了达到准确测距的目的,详述了各故障测距原理,并对各种测距方法进行了比较分析,通讯和计算机技术的发展,更为两端或多端测距算法提供了可能性。




谢谢!!帮帮忙,好吗?不管翻译多少都好,谢啦!!!!!!

Selects the undercurrent earth system movement method in our country 6 ~ 35KV electrical power system. The single-phase earth fault is the undercurrent earth system has the probability highest breakdown type, approximately composes all breakdowns number of times 80%. Although the regulations after stipulated the single-phase earth fault has the distribution network to be possible to continue to move 2h, but because the single-phase earth fault possibly can go a step further the development is two or the multi- spots breakdown, thus causes trips the power cut accident, therefore promptly determined the breakdown position eliminates the breakdown then to appear abreast in row extremely importantly. In order to after avoid the breakdown the occurrence or the breakdown eliminates the hidden danger as soon as possible, this article has carried on the thorough analysis and the elaboration on the undercurrent earth system single-phase earth fault. First carries on the analysis to various types neutral point earth way division and its the characteristic, when acts according to the single-phase earth fault the breakdown and the non- breakdown voltage, the electric current change characteristic, has designed the system insulation monitoring device, distinguishes the earth fault relatively according to each voltage characteristic the type and the breakdown. In addition also cancelled the arc coil blow-out principle and compensates the electrical network the action mechanism to carry on the explanation. Because the tradition pulled the road method by the line seriously to affect the power supply to be possible * the nature, the people studied proposed the many kinds of route selection plan, here 11 listed, and comprehensively carried on the synopsis and comparative analysis its advantages to these ten kind of breakdowns route selection plan principle. Finally, in order to achieve the accurate range finder the goal, has related in detail various breakdowns range finder principle, and has carried on the comparative analysis to each range finder method, the communication and the computer technology development, the beginnings and ends or in many ways range finder algorithm has provided the possibility.
