After a large amount of operations of the same tower multi-loop line, effective lightning protection becomes one of the difficult problems troubling the operation of the power transmission and distribution line, especially the same tower multi-loop power distribution line suffers from lightning stroke, cause many broken lines of the overhead insulated line, cause the power failure area that tripping operation is affected simultaneously to be larger than the single-loop line, the safe and stable operation influence to the power grid is also great, seriously influence the power supply reliability, because the area is limited, the distribution line often adopts insulated wire, there are trees or buildings and the like near the line, make the line difficult to suffer from direct lightning stroke when in operation. However, when trees or buildings near the line are directly struck by lightning, the potential of nearby objects is increased, the nearby objects may strike against the distribution line, the lightning strike breaks the line, and even the line or the trees may be ignited to cause forest fire, so that great loss is caused. Therefore, the research on the fact that the arc discharge process caused by the trees near the lightning strike line has practical significance on the lightning protection of the distribution line, for example, when vegetation such as shrubs and grass covers the lower portion of the distribution line, the electric field near the distribution line is distorted, and then thunderclouds are caused to hit the line. An overvoltage calculation model is established when trees near the lightning strike and the circuit are subjected to arc discharge, and the voltage characteristic of the arc is simulated by the model. The method comprises the following steps of (1) when trees near the lightning strike and the line are discharged, the line overvoltage has two obvious peak values in an induction stage and an arc discharge stage, and the voltage can reach hundreds of kilovolts. (2) When the tree height and the tree line distance are increased, the circuit arc overvoltage is increased, and the induction overvoltage changes slightly. When the amplitude of the lightning current is increased, the arc overvoltage and the induced overvoltage of the line are increased. As the wavefront time increases, the line arcing overvoltage increases. (3) The lightning arrester is installed to reduce the over voltage of the line arc to a certain extent, and different installation densities have different effects on reducing the voltage.
