In recent years, bird droppings flashover faults frequently occur on transmission lines. Based on the existing conditions of the laboratory, this paper explores the flashover mechanism of 110 kV bird droppings. A new type of bird droppings propulsion device was designed and developed, and the process of bird droppings falling in the natural state was simulated without voltage. According to several typical forms of bird droppings, the main findings are ① the bird droppings connected to the two poles are the most serious short circuit situation; ② the bird droppings flashover fault of the 110 kV line is actually a single-phase grounding fault of the line through a resistance, and the grounding resistance is between 20 and 300 kΩ; and ③ the conductivity is the most sensitive factor affecting bird droppings flashover. |
