As the reliability requirements of urban distribution network are getting higher and higher，the live working of distribution network in major cities across the country is rapidly expanding，and comprehensive evaluation for the safety of live working is very important． The safety of live working in distribution network is affected by many factors，such as the actual operating environment of urban distribution network，the safety production system and the comprehensive quality of the operators， which makes it appear as a hierarchical and non － linear comprehensive evaluation． To this end，a comprehensive evaluation method using G1 weighting method that does not require consistency check is proposed． Through in － depth analysis of the characteristics of live working，a comprehensive evaluation index system for the safety of live working in distribution network is established，and then G1 weighting method is used to determine the respective weights of each index factor，and at last the comprehensive evaluation results are obtained by calculation． Finally，the evaluation and verification for the safety of an actual live working site demonstrates the rationality and effectiveness of the proposed method，which can provide a reference for the safety management of live working sites．
