Abstract

The invention discloses a two-circuit line breaking and four-circuit cable leading-down tower. The two-circuit line breaking and four-circuit cable leading-down tower comprises a tower body and a ground wire bracket, wherein the ground wire bracket is arranged on the top of the tower body. An upper wire cross arm is arranged below the ground wire bracket, a middle wire cross arm is arranged below the upper wire cross arm, a lower wire cross arm is arranged below the middle wire cross arm, and a cable leading-down auxiliary cross arm is arranged below the lower wire cross arm. The ground wire bracket is vertical to the target line direction. The upper wire cross arm, the middle wire cross arm, the lower wire cross arm and the cable leading-down auxiliary cross arm are respectively of a cross shape, and the included angle between cross arm bodies of the upper wire cross arm, the middle wire cross arm, the lower wire cross arm and the cable leading-down auxiliary cross arm and wires respectively connected to the cross arm bodies is 45 degrees. According to the invention, one base rod tower is adopted for achieving two-circuit line breaking and cable leading-down, there is no need to adopt two base rod towers, and therefore the line investment is lowered and the influence to target lines is reduced to the maximum degree.

Description

Tower under four times cable leadings is cut-off in double loop
technical field:
The present invention relates to ultra-high-tension power transmission line technical field, particularly relate to a kind of double loop and cut-off tower under four times cable leadings.
background technology:
In existing work transmission line, double-side opening scheme under cable leading of breaking in double loop adopts two base double loop cable terminal pole (see figure 1)s usually, cross-arm is assisted to realize the effectively fixing of suspension string and arrester by increasing one deck below cross-arm under the tension-resistant rod of double loop, and utilize wire jumper by wire around causing suspension string, arrester and cable head junction, thus under realizing the cut-offfing and draw of circuit.
Existing shortcoming of cut-offfing scheme main has:
Need newly-built two base shaft towers to complete to cut-off, shaft tower Quantity is more, and construction cost is higher, and column foot floor space is larger.
summary of the invention:
The object of this invention is to provide a kind of double loop and cut-off tower under four times cable leadings, a base shaft tower of sampling, to realize cut-offfing and under cable leading, avoiding employing two base shaft tower of double-circuit line, reduces track investment, at utmost reduces the impact on target line.
In order to solve Problems existing in background technology, the present invention is by the following technical solutions: it comprises tower body, earth wire support, described tower body top is provided with earth wire support, upper conductor cross-arm is provided with below earth wire support, middle wire cross-arm is provided with below upper conductor cross-arm, below middle wire cross-arm, lower wire cross-arm is set, auxiliary cross-arm under being provided with cable leading below lower wire cross-arm, described earth wire support is perpendicular to target line direction, described upper conductor cross-arm, middle wire cross-arm, lower wire cross-arm, under cable leading, auxiliary cross-arm is all in cross, and upper conductor cross-arm, middle wire cross-arm, lower wire cross-arm, under cable leading, each cross-arm of auxiliary cross-arm is all 45 ° of angles with the respective wire be connected.
The present invention has the following advantages compared with cut-offfing scheme with routine:
(1) cut-off with conventional double loop and draw compared with lower scheme, under four times cable leadings are cut-off in double loop of the present invention, tower decreases newly-built shaft tower quantity, reduces column foot and takes up an area and civil coordination resistance, reduction construction investment.
(2) cut-off with conventional double loop and draw compared with lower scheme, under four times cable leadings are cut-off in double loop of the present invention, tower obviously shortened in basis cast, shaft tower resistance and payingoff construction time, the time of cut-offfing target line and having a power failure can be reduced, at utmost reduce the impact on target line.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is wiring schematic diagram of the present invention.
detailed description of the invention:
With reference to Fig. 1-2, it comprises tower body 1, earth wire support 2, described tower body 1 top is provided with earth wire support 2, upper conductor cross-arm 3 is provided with below earth wire support 2, middle wire cross-arm 4 is provided with below upper conductor cross-arm 3, below middle wire cross-arm 4, lower wire cross-arm 5 is set, auxiliary cross-arm 6 under being provided with cable leading below lower wire cross-arm 5, described earth wire support 2 is perpendicular to target line direction, described upper conductor cross-arm 3, middle wire cross-arm 4, lower wire cross-arm 5, under cable leading, auxiliary cross-arm 6 is all in cross, and upper conductor cross-arm 3, middle wire cross-arm 4, lower wire cross-arm 5, under cable leading, each cross-arm of auxiliary cross-arm 6 is all 45 ° of angles with the respective wire be connected.
Between upper conductor cross-arm and each corresponding cross-arm of middle wire cross-arm, between middle wire cross-arm and each corresponding cross-arm of lower wire cross-arm, all cable bearer is installed between lower wire cross-arm with each corresponding cross-arm of cross-arm auxiliary under cable leading, support insulator and cable head, the present invention is arranged in the middle of target line, target line is cut-off in both sides by the present invention, corresponding lead is connected on the insulator string of corresponding cross-arm, and be connected with the cable head on the cable bearer of below by wire jumper, thus under meeting electric clearance condition, a base shaft tower is utilized to realize cut-offfing of double-circuit line and under cable leading.
