Research on Tree-Line Grounding Fault Identification Technology based on Primary and Secondary Fusion Switch

Aiming at the problem of insufficient sensitivity of column switch to detect single-phase grounding faults of small-current grounding system, this paper proposes to establish a classification and identification model of tree line faults through the tree line discharge fault identification method based on the characteristics of the fault travelling wave currents, to establish an arc grounding fault identification model based on the arc grounding fault identification method based on the computer vision, to establish an arc grounding fault identification model, and to use intelligent algorithms through the multi-source signal fusion technology to The data of micro weather station and inclination sensor are fused with traveling wave and vision data to form a new tree line grounding fault recognition method. The experiment proves that this method can effectively recognize tree line grounding faults and guarantee the safety of power grid.
