[0002] With the development of economy and society, power users have higher and higher requirements for power supply reliability. As the main mode of urban distribution network maintenance, distribution network non-stop operation, according to the requirements of power safety work regulations, the distance between the phases of the cable conductor should be kept outside the safe distance specified by the voltage level. However, in actual operation, the phase distance is often close or the arc sag is large due to the need to hang the cable head for bypass operation. The contact between the flexible cable and the conductor is easy to cause instantaneous phase-to-phase short circuit fault under the wind swing. This increases the risk of danger to the operators and even causes unnecessary power outages, reducing the reliability of power supply. Therefore, it is urgent to design an auxiliary tool according to the structural characteristics of the existing distribution network line to ensure that the phase spacing meets the safe distance specified by the voltage level.
