Abstract
The utility model discloses a 66KV overhead line three-phase phase-converting iron tower, which consists of a tower body, an upper cross arm, a lower cross arm, two trusses, two diagonal tension materials, two angle steels, two combined strings, two pendulous strings, conducting wires A, B and C and two bypassing lead wires, wherein the upper part of the tower body (the head of the tower) is provided with the upper cross arm and the lower cross arm; the two cross arms respectively consists of the truss, the diagonal tension material and the angle steel; the wires at the two sides of the head of the tower are suspended on the cross arms and the main tower body by strain insulator strings, and are provided with the two bypassing lead wires to pass through the two combined strings and the two pendulous strings; and the three-phase conducting wires are arranged in the shape of a CAB triangle. The three-phase phase-converting iron tower is novel in conception, reasonable in design and reliable in work, can realize the one-off integral conversion of the three-phase wires by means of the base, can reduce the amount of the line iron towers compared with the phase (position) conversion of the straight line iron tower, optimizes the integral investment, and improves the safe reliability of the line.
Description
Technical field:
The utility model relates to a kind of overhead wire shaft tower that is used for power industry, industrial and mining enterprises' transmission line of electricity.
Background technology:
The 66KV overhead wire is particularly a kind of critical facility of oil field, colliery, power supply department extensive use of power industry, industrial and mining enterprises' transmission of electricity core network, and its safe operation is significant to guaranteeing ordinary production.In the production actual moving process at the scene because the starting point of circuit and terminal point electric substation door structure phase sequence is not corresponding or circuit is long is the equalizing contactor capacitance current, need in the line between part change the arrangement orientation of lead in the space.At present, usually adopt three basic tangent suspension towers and roll mode commutation (position), though this kind mode can achieve the goal, but shortcoming also clearly, need to increase iron tower quantity investment is increased, and the tumbling-type transposition makes tangent suspension tower be subjected to an extra lateral force, iron tower safe handling coefficient reduces, the corresponding increase in basis, and then influence all fronts road security reliability.
The utility model content:
Thereby the purpose of this utility model is to provide a kind of usefulness can realize the 66KV overhead wire commutation iron tower of three-phase conducting wire Integratively transposition can minimizing line steel tower quantity, raising line security reliability once base.
The utility model is to realize like this.This kind commutation iron tower is by tower body, last cross-arm, following cross-arm, truss, tiltedly draw material, angle steel, the combination string, string dangles, lead A, B, C, crossing lead-in wire forms, its structure, assembled relation is as follows: tower body top (tower head) is provided with, following two cross-arms, two cross-arms are respectively by truss, tiltedly draw material and angle steel to constitute, tower head both sides lead adopts strain insulator string to hang on cross-arm and the tower body master material, and be provided with lead-in wire by the combination string, dangle to go here and there and draw, wherein three-phase conducting wire is the setting of CAB rounded projections arranged: the lead-in wire of crossing of former upper conductor A is fixed through the suspending weight string, go downwards to the position of former lower wire B, realize the transposition of A to B, the mistake of former lower wire B goes between up through the combination string, the string that dangles is fixing, go downwards to the position of former lower wire C then, realize the transposition of B to C, the lead-in wire of crossing of former lower wire C is fixed through the string that dangles, be up to the position of former upper conductor A then, realize the transposition of C to A.
The utility model is novel, and is reasonable in design, reliable operation, this kind iron tower utilizes a base can realize the Integratively transposition of three-phase conducting wire, compare with tangent suspension tower commutation (position) and can reduce line steel tower quantity, optimize whole investment, improve the security reliability of circuit.
