Problems solved by technology

[0003] In areas with obvious droughts and floods and obvious rainy seasons and dry seasons, when the rainy season alternates with the dry season, especially when the rainy season comes after the dry season, thunderstorms come first, and then it rains, it is easy to damage the electrical equipment due to incoming electrical equipment, and the rainwater will infiltrate into the ground before the rain. A sudden lightning strike before reducing the grounding resistance is also likely to damage electrical equipment

Embodiment 1

[0045] Implementation example 1, such as Figure 1-6 As shown, a grounding device for a power system is characterized in that:

[0046] Including a grounding nail, the grounding nail includes a nail body 1, a central hole 10, a self-tapping thread 11, a drain hole 100, and an air pressure channel 51; the nail body 1 has a tapered tip; the self-tapping thread 11 is located outside the nail body 1, The self-tapping thread 11 makes the grounding nail have the function of self-tapping into the ground; the central hole 10 is located in the nail body 1, and the axial direction of the central hole 10 is the same as that of the nail body 1. The central hole 10 is a semi-through hole, and the central hole The external opening of 10 is located at the tail end of the nail body 1, that is, the end opposite to the tip; the drain hole 100 is located in the nail body 1, and the drain hole 100 is a full through hole, and the openings at both ends of the drain hole 100 are respective...

Embodiment 2

[0063] Implementation example 2, a kind of grounding equipment for power system, on the basis of implementing the technical solution described in example 1, increase the thin paper used for packaging; the thin paper is attached to the center hole 10 in the nail body 1 of the ground nail Block the opening of the center hole 10 on the opening; the thin paper is pasted on the opening where the discharge hole 100 in the nail body 1 of the ground nail is connected with the outer wall of the nail body 1 to seal the opening.

[0064] Peel off the thin paper on site before installing the grounding device.

Embodiment 3

[0065] Embodiment 3. A grounding device for a power system is improved on the basis of Embodiment 1. The inward opening 512 of the air pressure channel 51 is located at the bottom of the central hole 10 in the nail body 1 of the grounding nail.

Abstract

A grounding device for a power system is characterized by comprising a grounding nail, a shield (3), a heavy hammer (415), a rubber plug (416), a sealing sheet (61), a thread-like object (410), an air pressure balancing plug (411), and a counterweight(813), wherein resistance reducing agent (20) is arranged in the central hole (10) of a nail body (1), the heavy hammer (415) and the rubber plug (416) apply pressure to the resistance reducing agent (20), and the counterweight(813) adjusts the pressure on the resistance reducing agent (20) through the heavy hammer (415). The nail body (1) of the grounding nail of the grounding device for the power system further has a thin packaging paper. The power system employs the grounding device. The grounding device and the power system are rapid for installation and convenient for maintenance.

Description

Technical field [0001] The present invention is an electricity equipment, and especially involves a grounded equipment for power systems. Background technique [0002] Grounding nails refer to the equipment that is used to ground for grounding. The existing technology generally directly uses corner iron as the grounding of grounding into the ground. Due to the strong resistance and climate correlation of the soil, the effect of drought and flooding situation on the resistance of the land on the land resistance rateThe huge, the contact between the ground nails of the drought and flooding situation also has a huge impact, so the grounding situation of the drought and flood, especially the drought docking ground equipment, has a huge impact. [0003] In areas where the drought and floods are obvious and the rainy season is obvious in the rainy season, especially when the rainy season is over during the rainy season, when the rainy season is coming, the thunderstorms and the rain fi...
