Abstract
The invention relates to a multilayer copper-clad aluminum conductor, which comprises circular aluminum-magnesium bodies. The multilayer copper-clad aluminum conductor composed of the plurality of circular aluminum-magnesium bodies is a circular base core. The round base core is internally provided with an optical grating fiber carved with temperature measurement optical gratings, and a cooling channel flexible copper pipe. Optical grating temperature measuring points are formed on the optical grating fiber at predetermined intervals. The cooling channel flexible copper pipe is a flexible copper pipe provided with an insulation film wrapping layer and of the same length as the circular aluminum-magnesium bodies. Tin layers are arranged on the outer layers of the circular aluminum-magnesium bodies. A copper layer is sprayed between each circular aluminum-magnesium body and the corresponding tin layer. The copper layer is a chromium-copper alloy and comprises the following components in percentage by mass: 60-80% of copper, 10-25% of chromium, 5-10% of Si, 1-3% of carbon and 1-5% of iron.
Description
Technical field
The present invention relates to a kind of plain conductor, particularly a kind of multilayer copper cladding aluminum conductor.
Background technology
As everyone knows, the critical role of copper conductor industry in the national economic development is more and more outstanding with effect, but traditional fine copper enamelled wire uses pure copper material mostly, but due to resource scarcity, fine copper price is higher, increases production cost, reduces the market competitiveness.In addition, the copper conductor temperature rise situation that is in operation cannot be monitored, and easily occurs to cause the phenomenon of whole cable bad because electrical lead load increase causes to heat up.
Summary of the invention
The technical solution adopted for the present invention to solve the technical problems is: a kind of multilayer copper cladding aluminum conductor, there is circular magnalium body, the described wire be made up of many circular magnalium bodies is circular base core, is provided with grating fibers and a cooling duct flexible copper tubing that an inscription has thermometric grating in described circular base core.Described grating fibers forms a grating point for measuring temperature at interval of predetermined distance.Described cooling duct flexible copper tubing is the flexible copper tubing with insulation film lapping layer identical with circular magnalium body length.The skin of described circular magnalium body is provided with tin layers, is coated with layers of copper between circular magnalium body and tin layers.
Described layers of copper is the component of chrome copper, mass percent: copper 60 ~ 80%, chromium 10 ~ 25%, silicon 5 ~ 10%, carbon 1 ~ 3%, iron 1 ~ 5%.
Compare as wire with existing fine copper, this wire is strengthened wire on-line monitoring, grasps variations in temperature, improves wire transmission capacity, reduces line loss, is improved safe operation of electric network.In the middle of circular base core, be provided with cooling duct, enable cooling fluid carry out circulating cooling in wire inside, lower the temperature directly to wire.
