background technology:
Work transmission line construction is the important component part in power grid construction, to take on the effect of transmission, distribution, pressure regulation in power system.In view of the principle of selecting the best qualified of transmission line of electricity to transmission corridor is identical, for the consideration reducing costs, reduce occupation of land, transmission line of electricity selects parallel cabling usually.By the impact of transformer station's drop point site, newly-built circuit often with built crossing elimination, according to regulatory requirements, the circuit that voltage is higher is generally erected at the top of the lower circuit of voltage, the electrical network common line of same voltage gradation should be erected at above industrial siding, therefore transmission line of electricity first occurs repeatedly across the situation of rear brill (or after subdrilling across).
In Practical Project, for transmission line of electricity first across the situation of rear brill (or after subdrilling across), affect by landform and site environment, only adopt a base shaft tower to be often difficult to direct realization, usually need to take following several means:
1) by boosted voltage grade higher line road or the lower circuit of reduction electric pressure, but cause line outage, increase line construction cost.
2) mode that employing overhead crossing, cable drill are got over, but cost of putting cable underground is higher, and circuit is not easy to patrol and examine after building up simultaneously.
In sum, such scheme constructional difficulties and comprehensive cost is higher, is unfavorable for engineering construction.
summary of the invention:
The purpose of this utility model is to provide the change of a kind of single loop and exhales high shaft tower, and the line crossing side wire of this shaft tower is presented font and arranged, identical with conventional line arrangement, avoids the impact on adjacent tower wire arrangements; The brill of this shaft tower is got over side and is adopted compact arrangement mode, have compressed lead, ground wire to ground level, optimize further and bore Vietnamese side's case, the possibility of reduce old track remodelling, putting cable underground.
In order to solve Problems existing in background technology, the utility model is by the following technical solutions: it comprises tower body, top layer ground wire cross-arm, support insulator, be provided with upper strata below top layer ground wire cross-arm and cross over wire cross-arm, be provided with middle level below upper strata leap wire cross-arm and assist cross-arm, middle level is assisted below cross-arm and is arranged lower floor's brill more wire cross-arm, described top layer ground wire cross-arm is made up of the both sides cross-arm perpendicular to line direction, described upper strata is crossed over cross-arm and is formed by perpendicular to one deck both sides cross-arm of newly-built line direction and the monolateral cross-arm of one deck, described middle level assists cross-arm to be made up of the multilayer both sides cross-arm perpendicular to newly-built line direction, described lower floor bores more cross-arm and is made up of one deck both sides cross-arm perpendicular to newly-built line direction, described support insulator is fixed on middle level and assists each cross-arm taper of cross-arm and tower body brill to get over above side line road, be fixed on the support insulator of cross-arm taper perpendicular to newly-built line direction, be fixed on the support insulator that tower body bores above more side line road and be parallel to newly-built line direction, the jumper string of described top layer ground wire cross-arm place suspension strap stay pipe.
The utility model achieves single loop change by a base shaft tower and exhales high boring to cross over, reduce first across cross link transformation in rear brill (or after subdrilling across) engineering and the probability of putting cable underground, avoid the power failure of cross link, add electric network reliability, reduce construction cost, have compressed the lead wire and earth wire distance to the ground boring more shelves further.
