[0002] At present, the jumper string is an important component in the power transmission line, which is mainly composed of conductors, clamps and insulation strings. In the transmission line, when the conductor needs to be transferred and transitioned at the tower, the jumper string can ensure that the current can be safely and smoothly transmitted from one conductor to another, maintain the electrical continuity of the line, and ensure the normal transmission of electric energy. For example, on the tension tower, two sections of conductors in different directions are electrically connected through the jumper string to avoid current interruption;
[0003] After the jumper connects the conductors on both sides, the wind blows and causes the conductors to swing, which tends to cause the tension string to tilt.

[0012] The present invention provides a jumper string for preventing the conductor tension string from tilting. It has the following beneficial effects:
[0013] 1. The jumper string for preventing the inclination of the conductor tension string cooperates with the outer groove ring and the inner convex ring. Before fixing, the clamping block can be rotated between the clamping frame and the slide plate and adjusted according to the angle of the conductors on both sides of the pole tower. After fixing, the outer groove ring and the inner convex ring are tightly fitted, and the annular protrusion of the inner convex ring is inserted into the annular groove of the outer groove ring to increase the contact area between the outer groove ring and the inner convex ring. When the swing of the conductor drives the tension string of the pole tower to tilt, the tension force is transmitted to the clamping block through the tension wire clamp, so that the outer groove ring and the inner convex ring restrict the clamping block, thereby preventing the tension string from tilting after the jumper is connected, causing the jumper to be disconnected from the conductor, causing the conductive path to be disconnected, and affecting power transmission.
[0014] 2. The jumper string for preventing the conductor tension string from tilting has the cooperation of the limit plate and the inner buckle block so that the top of the limit plate fits tightly with the plane of the bottom end of the inner buckle block, thereby limiting the angle between the insulating string and the equipment wire clamp. After the rotating tension string shows a tilting trend, the force is transmitted to the insulating string through the tension wire clamp and the equipment wire clamp. The limitation of the limit plate is used to make the insulating string unable to move, and the force is transmitted to the pole tower through the buckle block. The auxiliary jumper clamp and the tension wire clamp limit the tension string to prevent the tension string from tilting.
[0015] 3. The jumper string that prevents the conductor tension string from tilting, through the cooperation of the wire tube and the fixed block, after the pole tower tension string shows a tilting trend, the force is transmitted to the jumper clamp through the wire tube to conduct the force. At the same time, the pipe groove and the pipe hole of the wire tube conduct the heat of the jumper when conducting electricity. At the same time, the accumulated water can also be discharged on rainy days to avoid leakage.
[0016] Fourth, the inclined jumper string of the anti-conductor tension string uses the side clamping blocks to clamp the conductors and jumpers when the top clamping plate and the bottom clamping plate are close to each other. The arc surface of the opposite surface of the side clamping blocks is used to concentrate the conductors and jumpers at the center position between the top clamping plate and the bottom clamping plate during the clamping process, thereby ensuring the accuracy of the clamping position.
[0017] 5. The jumper string of the anti-cone tension string tilts, through the cooperation of the arc block and the conical panel, after clamping the conductor and the jumper, the jumper is brought into contact with the convex pattern of the arc block, and when the jumper and the conductor tend to separate, the jumper moves synchronously with the arc block through friction, and the arc block and the conical groove of the conical panel are used for sliding adaptation. The conical groove is used to increase the clamping force of the arc block jumper after the trend appears, thereby limiting the separation of the jumper and the conductor and improving the fixing effect.
