Problems solved by technology

[0003] In areas with obvious droughts and floods and obvious rainy 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 seep into the ground before the rain. A sudden lightning strike before reducing the grounding resistance is also likely to damage electrical equipment
[0004] In order to solve the problem of unstable grounding in the prior art in areas with obvious drought and flood, the inventors of the present invention developed a grounding system and developed a shield when solving this technical problem

Embodiment 1

[0053] Implementation example 1, such as Figure 1-6 As shown, a ground nail for power system is characterized in that:

[0054] 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 respectively connected to t...

Embodiment 2

[0070] 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.

[0071] Peel off the thin paper on site before installing the grounding device.

Embodiment 3

[0072] 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 shield for a grounding device is characterized in that the main body of the shield (3) is cylindrical, the shield (3) comprises an air pressure balance pipe (33) for balancing air pressure, a support (32) and a pulley (412), the air pressure balance pipe (33) is a through pipe, the inner cavity of the shield (3) communicates with the atmosphere through the air pressure balance pipe (33) when no other blocking object is found, the support (32) is positioned in the inner cavity of the shield (3), and the pulley (412) is positioned on the support (32). The shield cooperates with a grounding nail with a hole in the center for containing resistance reducing agent to form a grounding device, and cooperates with the pulley and a heavy hammer to form a resistance reducing agent injection force-applying system. An electric power system employs the shield. The shield and the electric power system are rapid to install and convenient to maintain.

Description

technical field [0001] The invention belongs to electric equipment, in particular to a shield for grounding equipment. Background technique [0002] The ground nail refers to the equipment used for grounding driven into the ground. In the prior art, the angle iron is generally directly driven into the ground as a ground nail. Because the resistivity of the soil is strongly related to the climate, the drought and flood conditions have an impact on the resistivity of the land. Huge, drought and flood conditions also have a huge impact on the contact between grounding nails and soil, so drought and flood conditions, especially drought, have a huge impact on the grounding conditions of grounding equipment. [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 th...
