    摘 要:為了進(jìn)一步提升配網(wǎng)不停電作業(yè)的開展范圍和作業(yè)安全性,對 10 kV 旁路作業(yè)技術(shù)進(jìn)行了分析。研究了配網(wǎng)不停電小旁路作業(yè)時(shí)的電磁暫態(tài)過程和機(jī)械受力情況,提出了基于斗臂車內(nèi)絕緣短桿作業(yè)法的新型小旁路作業(yè)方法。理論分析和試驗(yàn)結(jié)果表明,只要開發(fā)出電氣連接可靠且絕緣性能滿足帶電作業(yè)要求的作業(yè)工具,就可以消除旁路作業(yè)中操作架空線路過程的電壓和電流安全風(fēng)險(xiǎn),提高作業(yè)效率和供電可靠性。

    Abstract: This paper analyzed the bypass operation technology of the 10 kV distribution network to improve the scope and safety of the uninterruptible operation of the distribution network. It proposed a new small bypass operation method based on insulating lever operation after studying the transient process and the mechanical stress situation of the small bypass uninterruptible operation of the distribution network.The theoretical analysis and experimental results shown that the safety risks of voltage and current would be eliminated in the overhead line in the bypass operation process if technicians could design an operational tool that had the feature of reliable electric connection and the insulation property met the requirement of hot-line work. This new tool could help improve operational efficiency and promote the reliability of the power supply.
    Key words: 10 kV distribution network; uninterruptible operation; bypass operation; insulating lever operation; reliability of the power supply
