Description

Technical Field

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

[0002] Grounding protection refers to a protective wiring method that reliably connects the metal parts of electrical appliances (i.e., the metal structural parts insulated from the energized parts) that are normally not energized but may become energized after insulation damage or other conditions to a grounding electrode using a conductor. It is a measure to ground the metal casing of electrical equipment. This prevents strong current from passing through the human body when the metal casing becomes energized due to insulation damage or accidents, ensuring personal safety. A grounding protection device refers to the grounding electrode buried underground and the connecting conductor between the grounding electrode and the equipment. A grounding device is also called an integrated grounding device: a device that establishes an electrical connection between electrical equipment or other objects and the ground. A grounding device consists of a grounding electrode, a grounding busbar, a grounding down conductor, and a grounding frame. It is used to connect the electrical system to the earth, thereby protecting the safe and stable operation of the power distribution network.

[0003] Currently, distribution boxes in the market are usually equipped with foundations during installation to improve their stability and safety. However, due to the difficulty in ensuring the flatness of the foundation construction, the distribution box is not stable enough during installation, and an additional grounding electrode is usually required after installation, which brings inconvenience to the construction. To address this, a grounding protection device for distribution boxes is proposed. Utility Model Content
