Embodiment 1

[0037] The present invention is a composite material substation structure, comprising a supporting column 2 and an insulating beam 1 arranged on the supporting column 2, the supporting column 2 is used to support the insulating beam 1, the supporting column 2 includes a composite material circular tube, and the insulating beam 1 It includes a composite material round rod prepared by a pultrusion process, and an insulating shed is crimped on the outer wall of the composite material round rod; the composite material round tube includes a base layer, a strengthening layer, a buffer layer and an outer layer arranged in sequence from the inside to the outside , the ratio of the thickness of the base layer, strengthening layer, buffer layer and outer layer to the outer diameter of the circular tube is 0.5~0.6:0.1~0.2:0.1~0.2:0.1~0.2:15; the base layer is specifically: Mg, 4~6%; Cr, 0.1~0.2%; Mn, 2.5~3.0%, V, 2.0~2.5%, Ti, 5.0~5.5%, and the balance is Al; the strengthening layer is sp...

Embodiment 2

[0039] According to the composite material transformation frame described in Embodiment 1, the support columns 2 are two groups of single rods, each group of single rods includes at least two stages of composite material circular tubes prepared by braiding, winding and pultrusion technology, and the composite material circular tubes of each stage are The pipes are connected by flange 4.

[0040] figure 1 It is a schematic diagram of a single-rod support structure of the present invention; the support column 2 in the figure is two groups of single rods, and each group of single rods includes three-stage composite material round pipes prepared by braiding, winding and pultrusion technology, and the composite material round pipes at all levels adopt the method of Lan 4 is connected.

Embodiment 3

[0042] According to the composite material substation structure described in Embodiment 1, the support columns 2 are in four groups, each of which is a herringbone support column 2, and each herringbone support column 2 includes at least one level of cross braces 6 and four levels of support columns. Composite material round tubes prepared by braiding, winding and pultrusion process, the composite material round tubes at all levels are connected by flange 4, and the flange 4 on the side (inner side) close to the insulating beam 1 is provided with a fixing hole for fixing the cross brace 6 .

[0043] figure 2 It is a schematic diagram of a herringbone support structure of the present invention; the support columns 2 of the herringbone support structure are four groups, and every two groups are a herringbone support column 2, and each herringbone support column 2 includes two-stage cross braces 6 and six-stage adopting Composite material round tubes prepared by braiding, windi...

Abstract

The invention discloses a composite material power transformation framework which comprises a support pillar and an insulating cross beam arranged on the support pillar and is characterized in that the support pillar comprises a composite material circular tube; the insulating cross beam comprises a composite material round rod prepared through the pultrusion process; an insulating umbrella skirt is connected with the outer wall of the composite material round rod in a pressing manner; the composite material circular tube comprises a base layer, a strengthened layer, a buffer layer and an outer layer sequentially arranged from interior to exterior; the composite material power transformation framework has the beneficial effects of solving the problem that the existing composite material is poor in overall stability when applied to the power transformation framework, being light in weight, high in strength, stable in structure, convenient and fast in transportation and installation, corrosion resistant, salt mist and acid rain resistant, excellent in electric property, reliable in operation, capable of greatly reducing the framework span to realize compact arrangement, and small in later maintenance quantity.

Description

technical field [0001] The invention relates to a substation frame used in substations and transmission lines. Background technique [0002] The towers widely used in overhead transmission lines and substations at home and abroad mainly include wooden poles, concrete or prestressed concrete poles, reinforced concrete poles, steel pipe towers and iron towers. [0003] Due to the difference in service life, most of the tower poles used in overhead transmission lines and the substation structures used in substations have the coexistence of old and new, and the use of multiple structural forms. These towers and substation structures will be damaged, deteriorated and aged in different degrees during use. For example, some concrete structures have surface cracks, carbonization, spalling, and steel rust and swelling, and some steel structures have steel corrosion. , deformation (such as depression, twisting), bending, eccentricity and other damage, and with the increase of service...
