Description

Wire core and wire structure utilizing the wire core

technical field

A wire core and a wire structure using the wire core, especially a wire with a special conductor structure.

Background technique

After humans started using electricity, they continued to study how to transmit electricity. In the early stage of electrical development, they discovered the basic Ohm's law V=I×R, where V stands for voltage, R stands for resistance, and I stands for the voltage V is applied to the resistance R. The current of the resistance R, so theoretically whether electricity can pass through an object depends on the resistance of the object, and according to Ohm's law, it is known that the current I will pass through the path with the lowest resistance value, so when the same voltage is applied to an object, the current It will tend to flow through the part with the lowest resistance value on the object; in order to reduce the loss of electric energy as much as possible during the transmission of electric energy, in addition to using conductors with low resistance to transmit electric power, it is necessary to study various phenomena of electric power transmission on conductors, Among them is a phenomenon of "skin effect". The mathematical representation of "skin effect" is not repeated here. The physical manifestation of this "skin effect" is that the resistance of a conductor increases with the frequency of alternating current. Specifically, as the frequency of alternating current increases, the increase in the resistance of the conductor makes the current tend to flow on the periphery or surface of the conductor (as shown in Figure 1), so that the surface area of the conductor becomes larger when the alternating current is at the same frequency. Larger wires can conduct larger currents; in this case, if the wires still use the conventional circular section wires, the power will only pass through the wire surface, and most of the metal conductors in the center of the wires are useless waste of resources.

Considering the skin effect, the wire must change the shape or configuration of its conductor to conduct the maximum current, reduce the loss as much as possible and make full use of resources, and the specific method is to maximize the surface area of the conductor and minimize the current in the conductor The cross-section that does not flow through, the more specific conventional method is to change a single conductor into multiple conductors and bundle them into a multi-strand wire, so that the surface area of a single conductor can be enlarged to the surface area of multiple conductors. This type of conventional technology For example, China Taiwan Patent Certificate No. M319508 "Improved Cable Structure", the scope of the patent and the drawings reveal that there are two or more conductors wound together, so that the surface area of the conductor where the high-frequency current flows can be enlarged and the center of the conductor can be reduced. Cross-section, because this method has a low threshold for manufacturing technology, and the multi-strand wire can be applied to the voltage or frequency of most conductive cables, so it is widely used, and the basic technology of multi-strand wire can be extended Various changes; previous patents of other multi-strand wires, such as Taiwan Patent Certificate No. M339783 "Improvement of Wire Structure for Concentrating Solar Cell Modules", reveal that one or more wire cores are assembled together and covered at one time. White Teflon wire, forming a single-core or multi-core wire; another previous patent such as China Taiwan Patent Certificate No. M347650 "for the structure of 400KV cross-linked polyethylene (XLPE) extra-high voltage power cable", due to This previous case is used for high-voltage power cables, so it can be seen that a large number of copper core wires are bundled in its icon; more previous utility models such as China Taiwan Patent No. 394289 "Improvement of Wire Structure" and China Taiwan Patent Publication No. 405764 "Differential Pair Cable", Taiwan Patent Certificate No. M340532 "Energy-saving Wire and Cable" and many other previous patents.

The above-mentioned prior art is to increase the conduction current by means of multi-strand wires, but a more active approach is to try to increase the surface area of a single conductor, such as China Taiwan Patent No. I270087 "wire for power or signal conduction wire Core", the utility model discloses that a wire includes a core, which is characterized in that the core has an equi-shaped geometric segment and a non-conformal geometric segment connected between the equi-shaped geometric segments, and the non-equal geometric segment There is an extension section extending inward, so the surface area of the non-equal geometric section for conducting electricity or signals is larger than that of the isomorphic geometric section; although this utility model breaks through the previous technology of simply using circular conductor strands, it strengthens the conductivity ability, but the complexity of the process of manufacturing the non-conformal geometric segment is obviously far more than that of the conventional circular conductor, and the non-conformal geometric segments of different shapes have different physical strengths, resulting in the compression of the non-conformal geometric segments of different shapes. Or bending and other external forces are different, and may be inferior to circular conductors, so the manufacturing cost, speed and physical strength of the wire body limit the application of this utility model.

However, although multi-strand wires can be applied to a wide range, due to the pursuit of "GREEN POWER" or "GREEN ENERGY" goals in various countries, as well as the formulation of various energy-saving regulations, the transmission efficiency of power wires should also be improved to avoid power wires. The loss on the wire will have a negative impact on the energy consumption performance of electrical appliances. However, changing the shape of the wire may cause additional manufacturing difficulties and high costs, so there is still room for improvement.

Utility model content

This case proposes a wire core with an enlarged surface area of the conductor to facilitate the passage of high-frequency current, thereby increasing the amount of conduction current by expanding the path through which the current passes.
