接地降阻应用及存在问题分析

分析和探讨了降阻剂在实际工程使用中降阻稳定性、使用寿命、腐蚀钢接地体等问题 ,认为这里既有降阻剂本身的质量问题 ,又有使用不当的问题。因此就降阻剂的选择、使用提出了应综合考虑降阻剂自身电阻率、对钢接地体的腐蚀率、对环境有无污染和降阻剂的稳定性和长效性等因素 ,通过技术经济分析有效长期稳定地发挥降阻剂的降阻效果 ,减少对接地装置的腐蚀。介绍了GPF - 94高效膨润土降阻防腐剂的性能特点和在实际接地工程上的应用 ,提出了制定降阻剂的行业标准 ,规范降阻剂市场的必要性

ANALYSIS OF THE APPLICATION AND PROBLEMS OF RESISTANCE REDUCING MATERIAL

Problems of application of resistance reducing material and steel corrosion in grounding engineering, its stability and life are analyzed in this paper. The quality problem of resistance reducing material and its misemploy may be existed. The resistivity of resistance reducing material, the rate of steel corrosion, The stability of resistance reducing material and available time are considered. The advice for the selection and application of resistance reducing material is put forward, especially how to make the best of resistance reducing, reduce the erosion in grounding devices and prolong life of grounding devices is researched. The characteristic of anticorrosive, efficient resistance reducing material, GPF 94 bentonite and its application in practical engineering is introduced. The necessity of establishment of the industry standard is proposed for the safely and effective use of resistance reducing material.
