接地极的土壤腐蚀

接地极是接地装置的主要组成部分,接地极埋设在土壤中,用于泄流,保障电网和电气设备的安全运行。近年来,接地极的腐蚀损坏造成的事故屡有发生,接地极的土壤腐蚀引起了普遍的重视,防止接地极腐蚀已成为一个重要的研究课题。本文介绍了目前我国电网和电气设备接地极的选材,接地极土壤腐蚀的特点,并对接地极防腐蚀方法做了简单总结。

Soil Corrosion of Grounding Electrode

Grounding electrodes used to leak-off the current flow is a chief part of the earthing devices.The ground rods are generally buried in soil to guarantee the safe operation for the power grid and the electrical equipment.In recent years,people pay more attention to the soil corrosion of grounding electrode since accidents often reported.It is becoming an important subject to prevent grounding electrode from corrosion.The present paper gives a summary of the grounding electrode on the m aterials selection,cor...
