Problems solved by technology

[0002] In the multi-split high-voltage transmission lines of the power system, spacers need to be installed and used. Commonly used are two-split, three-split, four-split, six-split, and eight-split. The clamps are all made of metal casting, and anti-rust treatment such as chrome plating is carried out. Such products are heavy in weight, complicated in manufacturing process, and high in production cost. Under the action of the ingredients, it will slowly rust, affecting the service life of the equipment and the safety of the transmission line. In addition, the heavy weight increases the mechanical load of the line. The mechanical load on the line is even more serious, and there may even be serious accidents such as line breakage and tower collapse, causing major property and personal safety losses
In addition, the frame is assembled by connecting two symmetrical sheet panels, so there are many spare parts and assembly processes, resulting in a further increase in cost

Embodiment 1

[0024] Such as figure 1 and figure 2 As shown, a spacer frame for transmission lines, including two-split, three-split, four-split, six-split, eight-split spacers, etc., taking the four-split spacer as an example, includes a body frame 1 and is integrally formed with the body frame 1 The wire clamp support arm 2 is integrally formed by the following components, 65% of the mixture, 35% of the fiber yarn, wherein the mixture consists of 30 parts of m-phenylene polyester resin, 10 parts of aluminum hydroxide, 10 parts of calcium carbonate, 10 parts of talcum powder, 10 parts of kaolin clay, 10 parts of silicon micropowder, 10 parts of glass powder, 5 parts of thinner acetone, 2 parts of pigment paste, 1 part of curing agent methyl ethyl ketone peroxide, 1 part of accelerator cobalt liquid, 1 part of ultraviolet absorber parts mixed.

[0025] by figure 2 , image 3 and Figure 4 The shown spacer frame for transmission lines is taken as an example, including a body frame 1 a...

Embodiment 2

[0027] The rest are the same as in Example 1, except that it is integrally formed by the following components, 50% of the mixture and 50% of the fiber yarn, wherein the mixture consists of 25 parts of o-phthalic resin, 35 parts of diluent styrene, solidified It is prepared by mixing 2 parts of methyl ethyl ketone peroxide, 1 part of accelerator cobalt solution, and 37 parts of flame retardant aluminum hydroxide.

[0028] The fiber yarn of the present embodiment is used in the spacer frame of the power transmission line, and the specific way is as follows: Figure 4 , Figure 5 and Figure 6 As shown, the fiber yarn bundle 3 is continuously and reciprocally wound along the structural path of the body frame 1 and the clamp arm 2 . The winding direction of a part of the fiber yarn bundle 3 is circular winding along the shape of the body frame 1 and the clamp arm 2, and the other part of the fiber yarn bundle 3 is reciprocally cross-wound along the corresponding wire clamp arms,...

Embodiment 3

[0030] The rest are the same as in Example 1, except that the following components are integrally formed, 25% of the compound, 75% of the fiber yarn, wherein the compound consists of 99.7 parts of vinyl resin, curing agent dibenzoyl peroxide 0.3 part composition.

[0031] Wherein, the fiber yarn is continuous and is distributed in the spacer frame for power transmission line continuously, tautly and evenly along the path of the spacer frame frame for power transmission line.

Abstract

The invention discloses a conductor spacer framework for a transmission line, which is integrally solidified and formed by adopting a mixture which comprises resin and additives, fiber yarns and / fiber yarn products, so the mechanical strength of the conductor spacer framework for the transmission line is greatly increased, consequently, compared with the products with the same specifications, the conductor spacer framework for the transmission line has simple production technology, lower cost, a small product volume, a light weight and corrosion resistance, and the product is integrally formed, so the production efficiency is high.

Description

technical field [0001] The invention relates to a spacer bar for a power transmission line, in particular to a spacer bar frame for a power transmission line using a high-strength composite material. Background technique [0002] In the multi-split high-voltage transmission lines of the power system, spacers need to be installed and used. Commonly used are two-split, three-split, four-split, six-split, and eight-split. The clamps are all made of metal casting, and anti-rust treatment such as chrome plating is carried out. Such products are heavy in weight, complicated in manufacturing process, and high in production cost. Under the action of the ingredients, it will slowly rust, affecting the service life of the equipment and the safety of the transmission line. In addition, the heavy weight increases the mechanical load of the line. The mechanical load on the line is even more severe, and even serious accidents such as line breakage and tower collapse may occur, causing si...
