Example Embodiment

[0015] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0016] The invention provides a carbon fiber whisker reinforced contact wire, which is aimed at the existing aluminum-clad steel, copper-clad steel, silver-copper alloy or pure copper contact wire with low tensile strength, small elastic modulus, poor arc resistance and thermal expansion. Significant improvements have been made because of the large shrinkage coefficient and the inability to meet the technical requirements of electric locomotives for high-speed electrified railways. The tensile strength of carbon fiber is more than 8-10 times that of ordinary steel, the elastic modulus is better than that of steel, and it has excellent creep resistance, corrosion resistance and shock resistance; carbon fiber is light in weight, only 1 / 5 of the weight of steel; ca...

Abstract

The invention discloses a preparation method of a carbon fiber whisker contact net lead, and the contact net lead comprises a carbon fiber, a whisker, metal conducting media and additives. The carboncontent of the carbon fiber is not less than 90 percent, and the tensile strength is not less than 3500MP; the whisker is a zinc oxide whisker, a calcium sulphate whisker, a magnesium sulphate whisker, a magnesia whisker or a silicon carbide whisker; the metal conducting media are copper, silver, aluminum, magnesium and zinc or a copper alloy, a silver alloy, an aluminum alloy, a magnesium alloy and a zinc alloy; and the additives are nickel, tin and niobium. The integral contact net lead is in an annular structure, and two V-shaped notches are laterally symmetrically arranged at the upper part of one half of an outer ring. The carbon fiber whisker contact net lead has the characteristics of high tensile strength, large elastic modulus, good flexibility, light weight and easy installation,has the key characteristics of small change of lead tension and sag along with air temperature, and is suitable for the requirement of the power supply engineering of high speed railway contact netsor urban track traffic contact nets.

Description

technical field [0001] The invention relates to an electrified railway catenary conductor, in particular to a carbon fiber whisker reinforced catenary conductor and a preparation method thereof. Background technique [0002] At present, my country's electrified railway or urban rail transit catenary wire materials include cold-rolled pure copper, aluminum-steel composite wire, tin-copper, silver-copper, tin-silver-copper and other alloy wires, but the above materials can only be adapted to low-speed, medium-speed and quasi-high-speed power The locomotive meets the technical requirements of flow, but cannot meet the technical conditions of high-speed railway. At present, the catenary wires that can meet the technical conditions for electric locomotives with a speed of 300 kilometers per hour are mainly Cu-Mg-Re magnesium-copper alloy catenary wires. The raw materials of this wire are mostly imported from abroad, and the price is abnormally high. With the development of high-s...
