供电电极

井&地电阻率法是把供电电极放入井中，地面进行电位分布测量的一种电法勘探方法。

The hole-to-surface electrical resistivity method is one of electrical prospecting methods by placing an electric current electrode in a drill hole and measuring the distribution of electric potential on the earth 's surface .

供电电极的接触电阻与大地的电阻率成正比，与电极的粗细及入土深度有关。

The contact electric resistance of the power supply electrode is in direct proportion to earth electric resistance rate , and in relation to the diameter of the electrode and the depth of the earth .

按《规范》要求，对外线路、观测仪器、观测环境等进行检查，结果发现异常是由于供电电极老化，接地电阻远大于《规范》要求的30Ω所引起。

It is found that the anomaly was caused by electrode and high ground connection resistivity greatly more than 30 Ω which required by the rule .

结果表明：检测电极的铺设方式以及供电电极和参比电极的位置对漏洞定位有一定影响。

Analysis to the field tests shows that leakage location is effected by the detection electrodes lay mode , the position of the supply electrodes and the position of the reference electrodes .

传统的直流电法勘探的方法的装置是供电电极和测量电极都在地表排列。

No matter what electric sounding and electric profile methods in traditional electrical surveying methods , their field layout are that current electrodes and voltage electrodes are set on the earth 's surface .

膜上供电电极的位置对漏洞定位有一定的影响，在测量时应尽可能将供电电极远离测量区。

The position of the power supply electrodes on the liner has some effect on leak location , so during the course of detection , the power supply electrodes should be placed where has long distance to the detecting area .

同时，检测层的电势分布主要是由供电电极和漏洞造成，因此，参比电极的位置既要远离漏洞又要远离供电电极。

At the same time the distribution of electrical potential on the detection layer is mainly caused by the supply electrodes and the leak . So the reference electrode must be placed far from the leak and the supply electrodes .

所得结果可供电弧运动和电极侵蚀理论研究以及旋弧灭弧室设计参考。

The results are valuable for theoretical study on arc erosion and design for a rotating arc chamber .

供电采用JD-73、APS-1501直流稳压电源，观测采用FLUKE45型高精度多用表，供电与接收电极均采用普通铜棒。

The supply power is DC power with the type of JD-73 、 APS-1501 . FLUKE 45 dual display multi-meter is used to read experiment result . Supply and receive electrode are common copper poles .
