摘　　要：提高荷电率能直接优化避雷器的保护水平。避雷器荷电率的选择要考虑安全性和经济合理性两个方面的因素。笔者研究了直流母线避雷器带电考核试验时内部温升情况和长期带电考核试验结果,结合电阻片加速老化试验研究成果,提出国产典型直流母线避雷器最高允许荷电率可取90%。Improving the chargeability can directly optimize the protection level of arrester.The selection of chargeability for arrester should consider both the safety and economic rationality.The internal temperature rise and long-term live test results of DC bus arrester are studied.Combined with the research results of aging test for resistor,it is proposed that the maximum allowable chargeability of domestic typical DC bus arrester can be 90%.
