Abstract

The utility model discloses an interphase combined Y-type jumper string for a strain tower of a transmission line, which comprises connecting fittings and jumper composite insulators, an upper phase jumper overhang clip (8) and a lower phase jumper overhang clip (7); the jumper composite insulators comprise upper phase jumper composite insulators (2) and lower phase jumper composite insulators (5); three hang points are arranged on the upper phase jumper overhang clip (8); two hang points on the upper end of the upper phase jumper overhang clip (8) are connected with two connecting fittings at the lower end of the two upper phase jumper composite insulators (2) in acute angle; one hang point at the lower end of the upper phase jumper overhang clip (8) is connected with the connecting fitting at the upper end of the lower phase jumper composite insulators (5). The interphase combined Y-type jumper string for the strain tower of the transmission line overcomes the defect that a current jumper string can only hang one phase jumper, which needs to fell trees or extract soils and rocks. The interphase combined Y-type jumper string for the strain tower of the transmission line can reduce the cost of the jumper string, improve the relative height of the lower phase jumper, reduce tree felling, decrease soil and rock extracting, effectively reduce the engineering cost, and have excellent economic benefit.

Background technology

Existing compact strain tower wire jumper string is " I " type string, and it can only hang a phase wire jumper.The electrified body distance to the ground of existing compact strain tower is by phase wire jumper control down, in application of practical project often because phase wire jumper air gap issues down need be carried out trees felling or native stone evolution.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned existing disadvantages of background technology, and the alternate associating of a kind of power line tension tower Y type wire jumper string is provided.It can hang the two-phase wire jumper of compact strain tower simultaneously, and strain tower wire jumper height is low, big, the native stone evolution of trees cutting capacity amount big and the high problem of wire jumper string expense to have solved existing (compact or other form).

The purpose of this utility model reaches by following measure: the alternate associating of power line tension tower Y type wire jumper string, it comprises connection gold utensil and wire jumper synthetic insulator, it is characterized in that it also comprises phase wire jumper suspension clamp and following wire jumper suspension clamp mutually, described wire jumper synthetic insulator comprises phase wire jumper synthetic insulator and following wire jumper synthetic insulator mutually, and described upward phase wire jumper synthetic insulator and following phase wire jumper synthetic insulator are all connecting between the gold utensil; On the last phase wire jumper suspension clamp three hanging points are arranged, having two hanging points to be acute angle with two last connection gold utensils of wire jumper synthetic insulator lower end mutually on it connects, a hanging point of its lower end connects the connection gold utensil of following phase wire jumper synthetic insulator lower end and wire jumper suspension clamp connection mutually down with the connection gold utensil of following wire jumper synthetic insulator mutually upper end.

In technique scheme, the described connection gold utensil of going up phase wire jumper synthetic insulator two ends is a U type link.

In technique scheme, the connection gold utensil of described phase wire jumper synthetic insulator down upper end is a ball-eye, and the connection gold utensil of following phase wire jumper synthetic insulator lower end is a socket-clevis eye.

In technique scheme, it is 60 °～70 ° with angle between the last suspension clamp of wire jumper mutually that described two of going up phase wire jumper synthetic insulator (2) lower end connect gold utensil.

The alternate associating wire jumper of the utility model power line tension tower string has following advantage: after strain tower uses alternate associating wire jumper string, can reduce wire jumper string expense, the following wire jumper support of cancellation strain tower and promote phase wire jumper down to ground level, exhale height thereby reach the reduction strain tower, reduce shaft tower steel use amount, reduce the trees felling, reduce native stone evolution, effectively reduce project cost, have good economic benefit, obtained good environment, social benefit simultaneously.
