摘　　要：电流互感器油中单纯氢气含量超过注意值近年来频繁发生,弄清其氢气来源正确诊断其缺陷属性,对设备安全运行具有积极意义。了解其氢气产生机理是正确诊断缺陷属性的前提。通过对电流互感器油中氢气产生机理的研究,发现电流互感器单纯氢气含量超过注意值主要是因为设备材质和制造工艺所致,并非因设备故障而产生,并对此类设备的技术监督提出建议。In recent years, it occurs frequently that pure hydrogen contained in current transformer oil goes over its alert value. It is of positive significance to the safe operation of equipment to find out the source of hydrogen and then diagnose the property of defects. To clarify the generating mechanism of hydrogen is the precondition of correct diagnosis of defect properties. It has been discovered, by study of the generating mechanism of hydrogen in current transformer oil, that the accident of pure hydro- gen contained in current transformer over its alert value is mainly caused by the materials and manufacturing process of the e- quipment, not by the equipment failure. The proposals are put forward for the technical supervision of such kind of equipment.
