Problems solved by technology

[0003] Electrical equipment is generally divided into A, B, and C phases, which are required to be marked with yellow, green, and red respectively. At present, phase colors are generally achieved by pasting signs with phase colors on the outside of iron cross-arms or wooden cross-arms or by painting , when installing the distribution network cross arm, it will increase the process and increase the construction time, and the phase color of the sign or paint only forms a thin layer of color on the surface, which will expose various problems in the long-term operation, such as The paint will fade or even peel off after a long time, the durability, flame retardancy and insulation performance are poor, the strength is low, the service life is short, the operation and maintenance are difficult, it consumes materials and increases the labor intensity of the operator, and various safety hazard

Embodiment 1

[0022] A cross-arm of composite material distribution network with phase color, comprising a base 1, on which several installation holes 2 for installing insulators are opened, the upper surface of the base 1 is an arc-shaped plane protruding upward, and the base 1 From the inside to the outside, it includes a supporting layer 11 that provides support, an anti-wear layer 13 that prevents the supporting layer 11 from being worn, a colored layer 14 with a phase color, and a protective layer that reveals the phase color of the colored layer 14 and protects the colored layer 14 15. The support layer 11 is a steel plate made of 45# steel with an "L"-shaped cross section. The wear-resistant layer 13 is a ceramic layer wrapped outside the support layer 11. A seal is injected between the wear-resistant layer 13 and the support layer 11. Glue 12 and sealant 12 are composed of the following weight percentages: 30% special resin, 20% plasticizer, 5% anti-mold thinner, 5% anti-mold agent, ...

Embodiment 2

[0030] Using the thickness of the epoxy resin plate is 5mm, the thickness of the polytetrafluoroethylene film is 0.01mm, and the thickness of the epoxy resin plate in the replacement embodiment one is 2mm, and the thickness of the polytetrafluoroethylene film is 0.02mm. The technical features are the same as those in Embodiment 1.

[0031]Epoxy resin plate with a thickness of 5mm has a very high breakdown voltage. While reflecting the color, a thick layer of protective layer is formed outside the inner steel plate, which is suitable for the erection of high-voltage transmission lines. At the same time, because the epoxy resin plate is relatively Thickness greatly meets the insulation requirement, and the thickness of the polytetrafluoroethylene film only needs to be 0.01 mm to safely protect the colored layer 14 and reduce production costs.

Abstract

The invention discloses a composite power distribution network cross arm with phase colors. The composite power distribution network cross arm comprises a base and an insulator. A plurality of installation holes for installation of insulators are formed in the base. The upper surface of the base is an upward-protruding arc-shaped plane. The base comprises a supporting layer, an anti-abrasion layer, a coloring layer and a protective layer from interior to exterior, wherein the supporting layer provides supporting force, the anti-abrasion layer prevents the supporting layer from being abraded, the coloring layer has phase colors, and the protective layer reflects the phase colors of the coloring layer and protects the coloring layer. The supporting layer is a steel plate with an L-shaped cross section. The anti-abrasion layer is a ceramic layer wrapping the supporting layer. The coloring layer is a colorful epoxy resin plate. The protective layer is a polytetrafluoroethylene film. The cross arm is provided with the coloring layer, so that the phase colors can be prevented from being peeled off or faded, the bright phase colors are kept all the time, and meanwhile the labor intensity of operators is lowered.

Description

technical field [0001] The invention belongs to the field of power transmission equipment, and in particular relates to a composite material distribution network cross arm with phase color. Background technique [0002] At present, in the field of power facilities, the cross arm for transmission lines is an important supporting structural part of the transmission pole. One end of the cross arm is connected to the main body of the transmission pole, and the other end is hung with a transmission wire. [0003] Electrical equipment is generally divided into A, B, and C phases, which are required to be marked with yellow, green, and red respectively. At present, phase colors are generally achieved by pasting signs with phase colors on the outside of iron cross-arms or wooden cross-arms or by painting , when installing the distribution network cross arm, it will increase the process and increase the construction time, and the phase color of the sign or paint only forms a thin lay...
