In this paper, for the safety risks such as complex working environment of the distribution live work on 10 kV, the safety risk of the distribution live work on 10 kV of multi-circuits on the same tower in a certain town of Benxi is evaluated by using analytic hierarchy process and fuzzy comprehensive evaluation and the safety evaluation index system of live work including working environment, personnel quality, working equipment and protection, comprehensive management of safe work, field management is set up. Based on the safety evaluation index system of live line work, the relevant quantitative analysis is done, the risk factors of live line work are analyzed, and the safety level of the live work is determined. According to the computation results of safety evaluation of live line work, this method provides a scientific basis for the safety management of distribution live work on 10 kV when live line work of multi-circuits on the same tower is in a relatively good condition.
