Problems solved by technology

The large-span transmission lines under construction have been developed and extended to high-voltage, large-capacity, and long-distance. Only using traditional aluminum conductors can no longer meet the strategic deployment of "west-to-east power transmission, north-south mutual supply, and national networking". The need for large spanning transmission lines

Abstract

The invention discloses a manufacturing method of an aluminum alloy material special for high-voltage power transmission and transformation. The method involves the following raw materials comprising,by mass, 2%-10% of silicon, 0.1%-1.5% of manganese, 0.1%-0.3% of zirconium, 0.2%-0.6% of copper, 0.1%-1.5% of rare earth alloy, 0.2%-0.6% of graphene and the balance industrial pure aluminum alloy. The method includes the following specific operating steps that first, the industrial pure aluminum alloy is added into a melting furnace for fusion, and the temperature is kept to be 800 DEG C; then the silicon raw material is added into molten aluminum after being ground, stirring is conducted continuously in the adding process, and the temperature is kept to be continuously stirred for 30 minutes after the silicon is added; and afterwards, the temperature is lowered to 780 DEG C. According to the manufacturing method, the internal structure of the aluminum alloy is changed by adding the raremetal and graphene materials; Compared with the prior art, the overall performance of the aluminum alloy material manufactured through the method is remarkably improved, and particularly the electrical conductivity, the heat dissipation performance and the flexibility are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of metal preparation, in particular to a method for manufacturing an aluminum alloy material special for high-voltage power transmission and transformation. Background technique [0002] High-voltage transmission is a method of boosting the output voltage of the generator through a transformer in a power plant and then transmitting it. The reason why this method is used for power transmission is that in the case of the same power transmission power, the higher the voltage, the smaller the current, so that high-voltage power transmission can reduce the current during power transmission, thereby reducing the heat loss caused by the current and reducing the material used for long-distance power transmission. cost. [0003] With the rapid development of our country's national economy, the construction of the electric power industry presents a trend of leaps and bounds. The large-span transmission lines under c...
