Problems solved by technology
[0003] For the hazards of stray currents in high-voltage transmission systems, the commonly used protective devices are to lay buried metal structures away from high-voltage transmission lines or towers, or to install insulation shielding facilities near buried metal structures, but these methods are easily affected by terrain. Due to limited conditions, the protection effect is also very poor, and it is not convenient to carry out daily parameter tests on buried metal structures.

The invention discloses a stray current hazard protection device of a high-voltage power transmission system. The stray current hazard protection device comprises a connecting device, a stray currentguiding device, a cable, a buried metal structure, a welding spot and a copper pipe. According to the connecting device, when the buried metal structure is damaged by the stray current of the high-voltage power transmission system, the connecting device can be automatically conducted to discharge the stray current on the buried metal structure through the stray current guiding device, so that theburied metal structure is prevented from being damaged by the stray current of the high-voltage power transmission system, the welding spot is a connecting point of the cable and the buried metal structure, electric communication between the cable and the buried metal structure is guaranteed, the stray current guiding device and the cable are connected through copper pipe crimping, and connectionfirmness is guaranteed. The stray current hazard protection device of the high-voltage power transmission system has good economic benefits and social benefits, and is suitable for popularization andapplication.
Description
technical field [0001] The invention relates to a stray current hazard protection device for a high-voltage power transmission system, in particular to a stray current hazard protection device for a high-voltage power transmission system, and belongs to the technical field of corrosion and protection. Background technique [0002] When buried metal structures (such as buried pipelines) are parallel to high-voltage transmission lines for a long distance, due to electromagnetic induction, induced voltages and currents will be generated on buried metal structures. These induced currents are called stray currents. Stray currents will cause stray currents to interfere with corrosion of buried metal structures, and will seriously affect the safe operation of buried metal structures. On the other hand, when the buried metal structure (such as buried pipeline) is close to the tower of the high-voltage transmission system, the buried metal structure will also be affected by the inter...
