摘要
文中应用应力计算等相关知识论证了带电进行孤立档架空地线更换的可行性。并经过计算,提出在应力难以满足要求的情况下,通过放松架空地线弧垂的方法使带电作业在安全可靠的前提下能够进行。文中最后给出了相应计算结果,为带电更换架空地线提供了参考。
The feasibility of changing the overhead ground wire by live-working method is verified in this paper through stress calculation.According to the result,if the stress has exceeded the demanded level,the method of sag-easier can be used to guarantee that live-working process can be accomplished safely.Relevant calculation results are given in the end,providing reference for further use.
