摘　　要：在配网设备故障中,电缆中间接头故障率占50%以上,降低其故障率是提高配网供电可靠性的关键。采用电缆本体恢复技术实现电缆中间接头连接,具有以下优点:等径和异径恢复;连接牢固,电导率高;径向电场均匀分布,电能损耗小、载流量高;接头处弯曲半径小,可拖动;寿命长,与电缆同寿命。该电缆本体恢复技术具有可靠性高、故障率低等优点,可有效降低因电缆接头故障而造成的经济损失。In the distribution network equipment failure,the failure rate of cable intermediate joint accounts for more than 50%.Reducing the intermediate joint failure rate is the key to improve the reliability of distribution network power supply.In this paper,the cable body recovery technology is used to realize the connection of the cable middle joint,which has the following advantages:equal diameter and different diameter recovery,firm connection,high conductivity,uniform distribution of radial electric field,small power loss,high current carrying capacity,small bending radius at the joint,draggable;long service life and the same service life as the cable.The cable body recovery technology also has the advantages of high reliability and low failure rate,which can effectively reduce the economic loss caused by cable joint failure.
