The invention discloses a lightning stroke simulation test platform for insulated wires and tree obstacles in a 10kV distribution network. The lightning stroke simulation test platform includes a lightning stroke generation device, a vegetation model and a tower model, wherein according to the practical situation, the lightning stroke generation device is arranged above the vegetation model and the tower model, and is used for generating lightning stroke impulse voltage above the tower model and / or the vegetation model; the lightning stroke generation device includes an impulse voltage generation device, a suspending device, an insulation rack and a bar electrode; the insulation rack is suspended above the tower model through the suspending device; at least two suspending holes are formedin the insulation rack, and are used for mounting the bar electrode; the high voltage end of the impulse voltage generation device is connected with the bar electrode through a wire; the discharging end of the bar electrode is arranged downward vertically; and the bar electrode is used for discharging to the tower model. The lightning stroke simulation test platform for insulated wires and tree obstacles in a 10kV distribution network can simulate the discharging situation between the insulated wires and the tree obstacles under lightning stroke impact, and is conductive to improvement of accuracy and reliability of the theoretical basis for safety protection of the distribution network.
Description
technical field [0001] This application relates to the technical field of lightning strike test, in particular, it relates to a lightning strike simulation test platform for insulated conductors and tree barriers of a 10kV distribution network. Background technique [0002] With the large-scale transformation of the distribution network, more and more distribution network lines are transformed from bare wires to insulated wires. Compared with bare wires, insulated wires can prevent pollution and corrosion due to the existence of the insulating layer, have certain insulation performance, can reduce the phase spacing, narrow the line corridor, and can contact with trees. For thick insulation, it can have a long distance with trees. time contact. Although in the normal operation of the distribution network, there will be no discharge between the insulated wire and the tree barrier (tree), but in the case of lightning shock, the insulation layer of the insulated wire will break...
