And a binary-splitting spacer is used after the jumper repair pipe of the 500kV strain tower is repaired. During operation, the two split jumper spacer connecting clamping plates are frequently disconnected from the lead, so that the lead is abraded or broken by a plurality of strands. The invention comprises the following components: this binary divides conductor spacer is including dismantling left spacing support arm (1) and right spacing support arm (2) of connection, left spacing support arm on rotate and be connected with left arm lock (3), right spacing support arm on rotate and be connected with right arm lock (8), left spacing support arm with left arm lock on the recess butt joint form round hole (4) structure, right spacing support arm with right arm lock on the recess butt joint form regular hexagonal hole (5) shape structure. The invention is used for the binary-splitting spacer after the jumper repair pipe of the 500kV strain tower is repaired.
Description
The technical field is as follows:
the invention relates to a binary-splitting spacer for a 500kV strain tower jumper repair pipe after repair.
Background art:
the 500kV transmission line adopts 4-split and 6-split conductors, and the conductors are generally of three types including LGJ-400, LGJ-300 and LGJ-240. In order to ensure a reasonable gap between the jumper wire of the strain tower and the connecting hardware fitting, avoid fatigue damage of the jumper wire clamp and avoid damage caused by whip collision of a lead on the hardware fitting, the two split jumper wire spacers are gradually and widely used on the line strain tower. One end of the existing two-split jumper spacer is fixed at the jumper outlet, and the other end of the existing two-split jumper spacer is fixed on the grading and shielding ring or the connecting plate extension rod to play a supporting role so as to prevent the jumper from colliding and rubbing with the grading and shielding ring.
The invention content is as follows:
the invention aims to solve the problem that a plurality of strands of conductors are abraded or broken due to the fact that a connecting clamp plate of a two-split jumper spacer is frequently disconnected with the conductors in the operation process of the two-split spacer, and provides the two-split spacer for the 500kV strain tower jumper repair pipe after repair, which can prevent the occurrence of line trip accidents due to the fact that a repair pipe is abraded, improve the safety level of an overhead line and ensure safe and reliable operation of the overhead line.
The above purpose is realized by the following technical scheme:
the utility model provides a 500kV strain insulator tower wire jumper repaiies pipe repaiies back and uses binary fission conductor spacer, this binary fission conductor spacer is including dismantling the spacing support arm in a left side and the spacing support arm in the right side of connecting, the spacing support arm in a left side on rotate and be connected with left arm lock, the spacing support arm in the right side on rotate and be connected with right arm lock, the spacing support arm in a left side with the recess butt joint on the arm lock in a left side form the round hole structure, spacing support arm in the right side with the recess butt joint on the arm lock in the right side form six arris hole shape structures.
500kV strain insulator tower jumper wire repair pipe mend and use two division conductor spacers after, left arm lock with right arm lock on all rotate and be connected with the screw rod, the screw rod pass the opening and the nut threaded connection of the spacing support arm of corresponding side.
The 500kV strain tower jumper wire repair pipe is repaired by using the binary-division spacer, and the diameter of the round hole is 22 mm.
After the 500kV strain tower jumper wire repair pipe is repaired, a binary-splitting spacer is used, and the distance between the upper edge and the lower edge of the hexagonal hole is 31mm, 35mm or 40 mm.
Has the advantages that:
1. the invention is suitable for three conductor types of LGJ-240, LGJ-300 and LGJ-400, can effectively prevent the phenomena of grinding-off of a repaired pipe or grinding-off of a conductor and the like caused by the mutual grinding of the repaired pipe and other objects of the conductor, avoids the occurrence of line tripping accidents caused by the grinding-off of the repaired pipe, improves the safety level of an overhead line and ensures the safe and reliable operation of the overhead line.
2. The joints at two ends of the limiting support arm of the 00kV wire repair pipe can be detached and replaced at will, so that the device can be conveniently applied to crimping pipes with different sizes and connecting different parts.
3. The hexagonal clamp plate and the crimping pipe are not provided with gaps, and the crimping pipe cannot be separated from the clamp plate.
4. The special limiting joint for the jumper repair pipe can be replaced according to repair pipes with different sizes, and the arc joint with different sizes can be replaced at the other end according to different connecting parts.
Description of the drawings:
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. a left limit support arm; 2. a right limit support arm; 3. a left clamp arm; 4. a circular hole; 5. a regular hexagonal hole; 6. a nut; 7. a screw; 8. and (6) a right clamping arm.
The specific implementation mode is as follows:
example 1:
the utility model provides a 500kV strain insulator tower wire jumper repaiies pipe repaiies back and uses binary fission conductor spacer, this binary fission conductor spacer is including dismantling the spacing support arm 1 in left side and the spacing support arm 2 in right side of connection, the spacing support arm in left side on rotate and be connected with left arm lock 3, the spacing support arm in right side on rotate and be connected with right arm lock 8, the spacing support arm in left side with the recess butt joint on the arm lock in left side form round hole 4 structures, the spacing support arm in right side with the recess butt joint on the arm lock in right side form positive six arris hole 5 shape structures.
Example 2:
according to embodiment 1 the 500kV strain tower jumper wire is repaired and is used two division conductor spacers after, left arm lock with right arm lock on all be connected with screw rod 7 in the rotation, the screw rod pass the opening and the nut 6 threaded connection of the spacing support arm of corresponding side.
Example 3:
