The first end of the ground connector 32 is formed in an arc shape, so that the ground wire 31 may be wound around the first end of the ground connector 32. The first end of the grounding terminal 32 can be directly hung on the horizontal rod 300, so that the wire 10 outside the line of the capacitor voltage transformer 40 can be grounded through the grounding device fitting 20 and the grounding assembly 30. The support rod 33 is an insulating rod, and the second end of the grounding head 32 is connected with the support rod 33. The support rod 33 is used for connecting the grounding head 32 to the horizontal rod 300.
The working principle of the grounding device 50 is as follows:
first, one end of the ground wire 31 is connected to a first end of the ground head 32, then the ground head 32 connected to the ground wire 31 is connected to the horizontal rod 300 by using the support rod 33, and finally, the other end of the ground wire 31 is connected to the ground electrode 34, so that the ground of the ground device accessory 20 can be achieved, and the ground of the wire 10 connected to the ground device accessory 20 can be achieved, which is in line with the electric power safety work regulations, thereby avoiding potential safety hazards during maintenance.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present application. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
