Description

Technical Field

[0001] The utility model belongs to the technical field of grounding protection, and in particular relates to a grounding protection device for a high-voltage power distribution system. Background Art

[0002] There are several main reasons for the leakage of electrical equipment: long-term use or aging may reduce the insulation performance of electrical equipment; during the use of electrical equipment, components may be damaged due to external force or aging; the wiring, plugs and other components inside the electrical equipment have poor contact; in the circuit design process, if safety factors are not fully considered. In order to ensure the safe use of electrical equipment, the equipment should be inspected and maintained regularly, especially the insulation performance test. At the same time, ensure good grounding and follow relevant safety regulations to prevent leakage accidents. Leakage can cause electrical equipment or lines to be energized, and electric shock accidents may occur when people touch them, posing a threat to personal safety. Leakage may cause electrical equipment to overload or short-circuit, thereby causing equipment damage and affecting the normal operation of the equipment; the arcs and sparks generated by leakage may ignite surrounding combustibles and cause fires, and may also cause production equipment to shut down or run unstably, affecting production efficiency, and may even cause production accidents.

[0003] When electrical equipment or lines fail, there will be leakage. If these fault currents are not handled in time, they will pose a threat to personal safety. Utility Model Content

[0007] On the basis of the above technical solution, the grounding protection device of a high voltage power distribution system of the utility model can also be improved as follows:

[0008] Wherein, the grounding pile includes a conductive mechanism and a grounding mechanism; the conductive mechanism and the grounding mechanism are integrally arranged.

[0009] Furthermore, the conductive mechanism is a cylindrical solid structure.

[0010] The beneficial effect of adopting the above-mentioned improvement scheme is: by setting the conductive mechanism as a cylindrical solid structure, it conforms to the distribution law of the electric field and can increase the contact area with the ground, which is beneficial to improving the grounding protection effect.

[0011] Furthermore, the grounding mechanism is a concentric circle structure.

[0012] Furthermore, the top of the grounding mechanism is fixedly connected to the lower wall of the conductive mechanism.

[0013] Furthermore, the height of the grounding mechanism is 4 times the height of the conductive mechanism.

[0014] Furthermore, four groups of tripod structures are fixedly arranged at the lower end of the outermost concentric circle structure of the grounding mechanism, and the angle between each group of the tripod structures is 90°.

[0015] The beneficial effect of adopting the above-mentioned improvement scheme is as follows: by setting 4 groups of tripod structures fixedly arranged at the lower end of the outermost concentric circle structure of the grounding mechanism, the angle between each group of the tripod structures is 90°, which can enhance the overall stability of the grounding pile, and at the same time enhance the conductivity of the grounding protection device of the high-voltage power distribution system and improve the grounding protection effect.

[0016] Furthermore, the height of the tripod structure is 5 cm.

[0018] Furthermore, the grounding pile is made of aluminum material.

This enables the copper grounding protection device to maintain good working performance in different environments.

[0020] Furthermore, the grounding pile is made of copper material.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting the grounding pile to be made of copper material, aluminum has good electrical conductivity, so the aluminum grounding protection device has good electrical conductivity, can effectively and quickly transmit the grounding current to the ground, reduce the grounding resistance, and improve the grounding protection effect; aluminum can react with oxygen in the air, and a dense aluminum oxide film is generated on its surface to prevent the internal aluminum from being further oxidized, so the aluminum grounding protection device has good corrosion resistance and can maintain a good grounding protection effect for a long time; compared with other metal materials, the price of aluminum is lower, so using aluminum as the material of the grounding protection device can reduce the cost of the grounding protection device.
