Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection devices, in particular to a lightning protection grounding device for a transformer substation. Background Art

[0002] The function of the lightning protection grounding device is to introduce lightning current into the earth to ensure the safety of people and buildings. The grounding device is an important part of the lightning protection device. The grounding device discharges lightning current to the earth and limits the voltage of the lightning protection device to the ground from being too high. When the lightning protection grounding device currently used is used for grounding, the connection points are fixed with two contact pieces by screws. The disadvantage of this connection method is that after long-term use, the connection points will corrode and rust, which will greatly reduce the conductivity. In addition, the position angle of the connection point cannot be adjusted according to the direction of the conductive connection line. The conductive connection line needs to leave the vertical wall of the substation and connect to the lightning protection grounding device. This connection method will make the extended connection part of the conductive connection line easily broken by external force, so there are certain hidden dangers. For this reason, we propose a lightning protection grounding device for substations. Utility Model Content
