The utility model is by being arranged on basis by tower leg, tower leg is arranged variable cross-section tower body, Variable Cross-Section Towers arranges uniform section tower body with it, uniform section tower body is arranged pillar top and lightning arrester body junction plate, this structure independent of fortune line steel tower, on transport line road without impact, do not need to transform existing steel tower, and structure is simple, be easy to operation.The utility model is to being difficult to carry out the anchor support of corresponding transformation on transport line road or tangent tower is feasible, effective, easy-operating arrester mounting means.
Further, the utility model is the device of zinc oxide surge arresters near easily thunderstruck ± 500kV DC power transmission line steel tower, according to this pyramidal structure feature, the scheme of carrying out improvement and installation on tower should not be adopted, and column support type structure is independent of transporting line steel tower, without the need to transforming steel tower, the performance-adjustable of column support type structure epimere uniform section tower body common segment, can strengthen the compliance to on-the-spot actual landform, conducting wire sag change.
Further; the utility model only need organize this column support type structure of vertical corresponding height immediately below wire jumper or wire arrester high-pressure side electrode mounting points position can zinc oxide surge arresters device, is specially adapted to the arrester that cross-arm or tower body cannot carry out the anchor support of corresponding transformation and installs.
Further, according to the cross section property of uniform section tower body, by different tower body section independent assortment, different height requirement can be met, make pillar height meet the electric clearance requirement of arrester.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model ± 500kV DC power transmission line arrester mounting column formula structure.
Fig. 2 be in Fig. 1 in Fig. 1 along A ?A to sectional view.
Wherein: 1 is pillar top and lightning arrester body junction plate, and 2 is uniform section tower body, and 3 is variable cross-section tower body, and 4 is tower leg, based on 5,6 is arrester high-pressure side electrode, and 7 is wire, and 8 is arrester arc-shaped electrode, and 9 is lightning arrester body.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, of the present utility model ± 500kV DC power transmission line arrester mounting column formula structure is straight column type; The utility model comprises basis 5, tower leg 4, variable cross-section tower body 3, uniform section tower body 2, pillar top and lightning arrester body junction plate 1, tower leg 4 is fixed on basis 5, variable cross-section tower body 3 is arranged on tower leg 4, variable cross-section tower body 3 is arranged uniform section tower body 2, uniform section tower body 2 comprises some tower body sections, according to the cross section property of uniform section tower body, and can by different tower body section independent assortment, meet different height requirement, make pillar height meet the electric clearance requirement of arrester.The top of uniform section tower body 2 arranges pillar top and lightning arrester body junction plate 1.The tower body 3 of variable cross-section described in the utility model front is trapezoidal shape, and section is square structure.
