ある。DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable when a grounding rod having a known connecting pipe is driven into the ground and its grounding resistance is insufficient, and when it is desired to add a snow protection function to the grounding rod. This invention relates to a snow protection auxiliary grounding electrode that can be easily attached to a grounding rod as an auxiliary grounding electrode. In the figures, Figures 1 and 2 show an example of the snow protection auxiliary grounding electrode of the present invention. A protruding needle (3) is provided as shown in the figure, and a connecting tube (2) is inserted into the hole of the metal disc (1). FIG. 6 shows a known grounding rod having a connecting tube, where (4) is the grounding rod and (5) is the connecting tube provided at the end of the grounding rod (4). (6) indicates a connecting metal rod. Now, the above connecting pipe (
In order to easily attach the snow protection auxiliary grounding electrode of the present invention to a grounding rod (4) having a grounding rod (4) as shown in FIG. The tube type (5),
This problem can be solved by making the diameters of the tube type (2') of the connecting tube (2) of the electrically-protective auxiliary ground electrode the same. Figure 4 is a diagram showing a grounding rod (4) containing a connecting pipe (5) with a snow protection auxiliary grounding electrode attached and buried. In steps 1 to 1, the earth (7) is excavated to a size that allows the snow protection auxiliary ground electrode to be buried therein, and the ground rod (4) is driven. Then, connect the connection pipe (2) of the snow protection auxiliary ground electrode and the connection metal rod (2') (5') of the connection pipe (5) provided on the ground rod (4).
6) and attach it as shown in the figure to integrate it and backfill the excavation site.The area of contact with the ground will increase due to the addition of the snow protection auxiliary ground electrode, so the ground rod (4) In order to compensate for the lack of ground resistance, the snow protection auxiliary ground electrode is placed on the outer periphery of the metal disk (1) where the unequal electric field is focused.
Since the protruding needle (3) is provided, the protruding needle (6) discharges lightning electricity, and also has a snow prevention effect that reduces the steepness of the lightning wave front. The above has explained an example of the snow protection auxiliary ground electrode, but it is not limited to a circular plate as long as it has a connecting pipe (2) and a protruding needle (3). By providing the protruding needles (3) where the unequal electric field is focused, it is possible to obtain a snow protection auxiliary ground electrode having the same effect as described above. In short, the present invention makes the diameters of the connecting tube (5) of the known grounding rod (4) and the connecting tube (2) of the snow protection auxiliary grounding electrode (2) equal to each other, and makes the connecting metal This is a convenient and effective snow prevention auxiliary ground electrode created by the idea of integrating the attachment with the rod (6).
