Technical Field

[0001] This utility model relates to the field of power distribution network grounding protection technology, specifically a power distribution network grounding protection mechanism. Background Technology

[0002] A power distribution network refers to a power grid that receives electrical energy from the transmission network or regional power plants and distributes it locally or through voltage levels to various users via distribution facilities. Power distribution networks rely on distribution cabinets to distribute power. Distribution boxes contain a large number of distribution lines and electrical equipment. To ensure the safe and stable operation of power distribution boxes, grounding protection is required.

[0003] However, existing grounding protection measures for power distribution networks are insufficient, which can easily lead to safety hazards, and the connection and protection of grounding wires are not effective enough. Therefore, they do not meet the current needs. In response, we propose a grounding protection mechanism for power distribution networks. Utility Model Content

[0004] The purpose of this utility model is to provide a grounding protection mechanism for power distribution networks, so as to solve the problems mentioned in the background art, such as insufficient protection measures for grounding of existing power distribution networks, which easily cause safety hazards, and inadequate connection and protection effect of grounding wires.

A positioning groove is provided on one side of the connecting head. An arc-shaped conductor is provided on the outer surface of one end of the conductive rod. A positioning rod is provided on one side of the lower end of the connecting rod, and the positioning rod corresponds to the positioning groove. A screw cap is provided at the upper end of the connecting rod. A rubber plate is provided on the upper surface of the connecting block.

[0006] Preferably, the connecting rod passes through the drain plate and is fixed to the outer surface of the drain plate by screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model has a water-reducing plate on the top of the box, which can reduce the amount of rainwater remaining on the top of the box and prevent corrosion of the box, thus improving the protection of the box. A moisture-proof plate is installed on the inside of the box, which can reduce the impact of moisture on the internal working components and improve the working efficiency of the internal working components.

The limiting plate slides with the connecting rod, allowing the connector to be pulled out and the grounding wire to be connected and fixed. Then, the connector is inserted into the inner side of the connecting rod, reducing the difficulty for workers to connect the grounding wire and making it easier for them to connect.
