Definitions

  • the utility model relates to the technical field of high voltage transmission lines.
  • the transmission line towers of the existing wire-triangular arrangement mostly adopt a two-layer cross-arm arrangement (see Fig. 1), that is, the upper layer cross arm is arranged with one phase conductor, and the lower layer cross arm is arranged with two phase conductors, and the main disadvantages of the arrangement are as follows:
  • Two-layer cross-arms need to be set up, and the amount of steel used in the tower is increased, which increases the cost;
  • the utility model aims to provide a transmission pole tower with a three-phase conductor type-shaped cross-arm arrangement, which solves the requirement of three-phase cross-arm in the conventional conductor triangle arrangement pole to meet the three-phase conductor clearance requirement by using the common cross-arm arrangement.
  • the arrangement reduces the structural height of the tower while saving one layer of cross arm, saving manufacturing costs.
  • the utility model adopts the following technical solutions: It comprises a tower body, a wire cross arm, an upper insulator string, and a lower insulator string.
  • the tower body is provided with a wire cross arm, and the wire cross arm is mounted on the upper plane.
  • An upper insulator string and a lower plane are mounted with two lower insulator strings, and the three insulator strings form a "pin" shape.
  • the utility model adopts the common-shaped cross-arm arrangement of the utility model, wherein the three-phase wires are arranged in a shape of a character on the cross-arm of the same wire, and the two-phase wires are suspended under the crossarm of the wires by using the lower insulator strings in a horizontal arrangement, and the upper insulator is used.
  • the string fixes the third phase conductor above the conductor crossarm, which forms a figure-like arrangement with the two-phase conductor below the conductor crossarm.
  • the utility model utilizes the common cross-arm arrangement to solve the arrangement of the conventional wire-triangular arrangement pole that requires two layers of cross-beams to meet the three-phase wire clearance requirements.

Abstract

L'invention concerne une tour de transmission d'énergie pourvue de fils métalliques triphasés selon un agencement triangulaire à partage de traverse. La tour de transmission d'énergie comprend un corps (1), une traverse en fil métallique (2), une chaîne supérieure d'isolateurs (3) et une chaîne inférieure d'isolateurs (4). La traverse en fil métallique (2) est disposée sur le corps (1) de la tour. Une chaîne supérieure d'isolateurs (3) est montée sur un plan supérieur de la traverse en fil métallique (2), deux chaînes inférieures d'isolateurs (4) sont montées sur un plan inférieur, et les trois chaînes d'isolateurs présentent une forme « triangulaire ». La tour, de par son agencement à partage de traverse, pallie le défaut selon lequel deux couches de traverses en fil métallique sont nécessaires dans une tour à agencement triangulaire classique pour satisfaire une forme d'agencement requise par une distance électrique des fils métalliques triphasés. La hauteur structurelle de la tour est réduite, tout en se passant d'une couche de traverses en fil métallique, ce qui diminue les coûts de fabrication.
