By setting the first reinforcing block 2, the purpose of reinforcing the connection position between the first half pressure ring 1 and the clamping block 3 can be achieved, so that the clamping block 3 and the first half pressure ring 1 can be used in a better manner, and the problem of separation between the clamping block 3 and the first half pressure ring 1 can be avoided as much as possible during the use of the clamping block 3 and the first half pressure ring 1.

[0022] Connecting blocks 5 are fixedly installed at both ends of the second half pressure ring 8, and a clamping groove 13 compatible with the clamping block 3 is opened on the left side of each connecting block 5, and a second threaded opening 14 is opened on the upper surface of each clamping block 3. Two groups of second reinforcement blocks 9 are fixedly installed on the outer surface of the second half pressure ring 8, and the left side of each group of second reinforcement blocks 9 is fixedly connected to the right side of the connecting block 5. By setting the second reinforcement block 9, the purpose of reinforcing the connection position between the second half pressure ring 8 and the connecting block 5 can be achieved, so that the connecting block 5 and the second half pressure ring 8 can be better used in coordination, and the problem of separation between the connecting block 5 and the second half pressure ring 8 during the coordinated use can be avoided as much as possible.

[0023] Two fixing bolts 4 are arranged above the second half pressure ring 8, and the bottom end of each fixing bolt 4 passes through the second threaded opening 14 and is threadedly connected to the inner wall of the first threaded opening 12, and the outer surface of each fixing bolt 4 is sleeved with a first gasket 10, and the bottom surface of each first gasket 10 is in contact with the upper surface of the connecting block 5. By arranging the first gasket 10, the fixing bolt 4 can be better tightened to achieve the effect of protecting the surface of the connecting block 5, and the problem of damage to the surface of the connecting block 5 during the tightening process of the fixing bolt 4 can be avoided as much as possible.

[0024] The inner walls of the first half pressure ring 1 and the second half pressure ring 8 are fixedly installed with fasteners 6, and the outer surface of each fastener 6 is fixedly installed with two groups of stabilizing blocks 16, and a side surface of each group of stabilizing blocks 16 away from each other is provided with a third threaded opening 18, and the outer surface of each fastener 6 is fixedly installed with two groups of fastening blocks 7, and the side surfaces of the two groups of fastening blocks 7 away from each other are fixedly connected to the inner wall of the first half pressure ring 1 and the inner wall of the second half pressure ring 8 respectively. By providing the fastening blocks 7, the purpose of fastening the connection position of the fastener 6 can be achieved, thereby improving the stability of the fastener 6 and avoiding the problem of position movement of the fastener 6 during use.

After screwing it out, the staff pulls the clamping block 3 out of the clamping groove 13 to separate the first half pressure ring 1 and the second half pressure ring 8. After separation, the staff takes the first half pressure ring 1 and the second half pressure ring 8 to the place where they need to be installed and used, and then clamps the clamping block 3 into the clamping groove. Inside the connecting groove 13, the staff then screws the fixing bolt 4 into the second threaded opening 14 and the first threaded opening 12, and then, under the action of the fastener 6, fastens the high-voltage cable through the fastening bolt 11, the third threaded opening 18 and the nut 15, so as to achieve the effect of more convenient removal and disassembly of the equalizing ring, and try to avoid some of the original equalizing rings, which are too large during installation, making the installation process time-consuming and labor-intensive.
