Description

Two-split wire spacer with spring damping

technical field

The utility model relates to electric equipment, in particular to a two-split conductor spacer with spring damping.

Background technique

In transmission lines, the transmission capacity is increased by using split conductors. When two-split conductors are used, two conductors of each phase of the line are arranged side by side. The two wires in the same phase may collide and whip between the wires under the action of electromagnetic force and wind during operation, resulting in short circuit and damage to the wires, and the consequences are very serious.

A gap is formed on the end surface of the connecting pipe, and a damping mechanism that can move along the pipe wall is provided in the connecting pipe. The damping mechanism has two groups and is respectively located at both ends of the connecting pipe. One end of the damping mechanism passes through the gap The threaded hole on the connecting rod is connected with the connecting rod by detachable thread, and an opening is arranged on the pipe wall of the connecting pipe.

Further, the damping mechanism includes a base with a diameter larger than the diameter of the gap, a spring and a damping washer arranged on one end surface of the base, and a post that can be fixedly connected to one end of the base, and the post is located in the spring and the damping washer , There is a thread on the end of the connecting rod away from the base, the threaded end of the connecting rod passes through the gap and is screwed with the connecting rod, the damping pad is placed on the end face of the base, one end of the spring is against the end face of the damping washer, and the other end is against against one end of the skirt.

Further, the damping washer is made of rubber.

Further, the opening is a "cross" shaped opening formed by the crossing of a transverse opening and a longitudinal opening, and the width of the transverse opening is greater than the diameter of the post, the width of the longitudinal opening is greater than the thickness of the base, and the length is greater than the diameter of the base.

The beneficial effect of the utility model is: when the wire swings or whips due to wind load and external load of electromagnetic force, the damping mechanism can slide in the connecting pipe, and the damping effect of the spring weakens the energy applied to the wire by the outside, which can It can better suppress the effect of wire touching and breeze vibration.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described:

In the figure: connecting pipe 1, skirt 11, gap 12, connecting rod 2, threaded hole 21, wire clamp 3, base 4, post 5, spring 6, damping washer 7, opening 8, transverse opening 81, longitudinal opening 82.

As shown in Figures 1 and 2, the two-split wire spacer with spring 6 damping includes a connecting pipe 1, and a wire clamping portion is respectively provided at both ends of the connecting pipe 1, and the wire clamping portion includes a connecting rod 2, A wire clamp 3 is fixedly connected to the end of the connecting rod 2, a threaded hole 21 is provided on the end surface of the connecting rod 2 away from the wire clamp 3, and a circle of inwardly extending rings is respectively fixed on the end surfaces of the connecting pipe 1. The skirt 11 forms a gap 12 on the end surface of the connecting pipe 1 by the skirt 11, and a damping mechanism that can move along the pipe wall is provided in the connecting pipe 1. The damping mechanism has two groups and is respectively located in the connecting pipe. 1, one end of the damping mechanism passes through the gap 12 through the threaded hole 21 on the connecting rod 2, and the connecting rod 2 is detachably threaded, and an opening 8 is provided on the pipe wall of the connecting pipe 1.

The function of an opening 8 is: when it is necessary to install the wire clamping part on the damping mechanism, it is only necessary to find a steel pipe and insert it into the opening 8, fix the two ends of the wire clamping part, and use the steel pipe to twist The connecting pipe 1 just can install the wire clamping part on the damping mechanism.

Further, the damping mechanism includes a base 4 with a diameter larger than the diameter of the gap 12, a spring 6 and a damping washer 7 arranged on one end surface of the base 4, and a connecting rod 5 that can be fixedly connected to an end surface of the base 4. The rod 5 is located in the spring 6 and the damping washer 7, and the end of the connecting rod 5 away from the base 4 is threaded, and the threaded end of the connecting rod 5 passes through the gap 12 and is screwed with the connecting rod 2, and the damping pad is placed on the end surface of the base 4 , one end of the spring 6 abuts against the end surface of the damping washer 7 , and the other end abuts against an end surface of the skirt 11 .

Further, the damping washer 7 is made of rubber, and the damping washer 7 can provide certain damping for the spring 6 .

Further, the opening 8 is a "cross"-shaped opening 8 formed by the intersection of a transverse opening 81 and a longitudinal opening 82, and the width of the transverse opening 81 is greater than the diameter of the post 5, and the width of the longitudinal opening 82 is greater than that of the base 4 Thickness, length are greater than the diameter of base 4.
