Description

Wire and its covering material

This creation is a kind of wire and wire covering material covering the wire surface.

In the existing power system, the transmission of electrical energy depends on the transmission of large wires at high voltage to reduce the loss of electrical energy transmission. However, in the low-voltage distribution network at the customer end, it is difficult to avoid the electrical energy loss caused by the capacity of the electrical wires.

In addition, due to the popularity of power electronic equipment, the number and proportion of non-linear loads in the overall power grid continue to rise. Rectifiers, modulators, and heavy-load start switches all generate high-frequency noise and surges in the power grid. Harmonic pollution is becoming more and more serious, and the occurrence and deterioration of harmonic pollution will lead to increased transmission losses in the power grid, causing overload of electrical equipment and lines, causing line heating, and normal use of electrical equipment will also accelerate The aging of wires and electronic components may also cause noise, vibration, or noise and noise in electronic devices, which not only endanger the normal use of power users, but also cause safety problems due to the accelerated aging of various components.

In response to the harmonic problems in the power grid, there are currently passive filters, uninterruptible power systems and power factor correctors available for general users to protect electrical appliances or power users and reduce the harm caused by harmonics. However, power transmission in the power grid Problems such as loss, heat generation, and line aging remain to be resolved.

In view of this, one of the objects of the present invention is to provide a wire, which can reduce the harm caused by harmonics in the wire or the power grid, and reduce the problems of heat generation and aging of the wire.

In order to reduce the power loss, heating and line aging problems caused by harmonics in the power grid, the most intuitive solution is to reduce the resistance in the wire. However, if the existing wire is replaced with a core material with a higher conductivity wire For example, replacing aluminum wires with copper wires or copper wires with silver wires will have extremely high replacement costs and will be difficult to implement in practical commercial applications.

On the other hand, recent research on infrared rays has found that when far-infrared rays with a wavelength of 2.5 to 1000 microns, especially 2.5 to 30 microns, are irradiated to a conductor carrying current, energy is transferred to the conductor, and resonance and absorption occur in the conductor, causing Conductor molecules become active, the electrons in the conductor molecules will jump to a higher energy level, or even arrange the electrons in the direction of the spin. When a current occurs in the conductor, it will help to construct a rotating electromagnetic wave in the surrounding space. By energy band theory and quantum Spin-Hall effect theory can reduce the impedance of a conductor. Related technologies have been described in CN 104106197 patent and KR 10-0419312 patent.

Thus, the present invention provides a wire coating material, which includes an insulating base material and an infrared radiation material, and the infrared radiation material is mixed and distributed in the insulating base material in a powder form.

Wherein, the insulating base material may be plastic material or rubber material, the infrared radiation material may be tourmaline powder or ceramic modified tourmaline powder, and the weight percentage of the infrared radiation material may be between 0.05% and 8% In practice, the average particle diameter of the infrared radiation material may be less than 0.3 microns in practice.

The invention also provides an electric wire, which includes an electric wire core and an insulating sheath. The insulating sheath covers the electric wire core, and the insulating sheath is made of the foregoing electric wire coating material.

In the above electric wire, the electric wire core may be a single-strand or multi-strand metal wire.

In this way, the wire coating materials and wires provided by the present invention can be applied to power grids or electrical equipment. When harmonics occur during power transmission, infrared radiation materials emit infrared rays due to charge oscillations or temperature changes caused by high-frequency waves. The conductor material irradiated on the core of the wire reduces the impedance of the conductor, thereby reducing the high temperature and power loss caused by harmonics, maintaining the energy transfer efficiency, and avoiding the aging of the wire.

Please refer to FIG. 1, this embodiment discloses a wire, which can be used to transmit power, or can be further wound into a wire set, which can be used in a transformer or a motor. The electric wire in this embodiment includes an electric wire core 10 and an insulating sheath 20.

The electric wire core 10 is a core material capable of conducting electricity, for example, copper wire or other metal wires. The electric wire core 10 is a single-strand metal wire in this embodiment shown in FIG. 1, as shown in FIGS. 2 and 3 , It is also necessary to change the spiral winding of multiple strands of wire into a wire core. In addition, it is also feasible to use a single strand or multiple strands of pre-coated metal wire as the core of the wire in the creation. Preferably, the pre-coated insulating material is infrared-transparent material, For example, transparent plastic or infrared penetrating plastic.

The insulating sheath 20 is wrapped around the wire core 10 to prevent the wire core 10 from being exposed to the outside. Specifically, the insulating sheath 20 can be wrapped around the wire core 10 by extrusion coating to form a structure as shown in FIG. 1 Or, you can use a pre-manufactured ribbon structure to wrap the wire core 10 by winding or longitudinal coating to form the structure shown in Figure 2 or Figure 3, which are all feasible specific methods. . The insulating sheath 20 is made of a wire coating material prepared in advance, and the wire coating material includes an insulating base material and an infrared radiation material.

The insulating base material is preferably a plastic material or a rubber material, which has good insulating properties. Specifically, PP, PE, PU, PVC, TPR, or other plastics or rubbers with similar properties can be used. For the insulation, durability and flame resistance of the sheath 20, mica powder, ultraviolet absorber and other flame-resistant or flame-retardant mineral powder or other substances with similar properties can be added to the plastic or rubber used. Also Toner can be added to modulate the color of the insulating sheath. For the specific materials and available additives in the insulating base material, please refer to the fire protection composition described in TW I322176.

Infrared radiation materials have the ability to release infrared rays. The infrared rays are electromagnetic waves with a wavelength of 2.5 to 1000 microns, especially electromagnetic waves of 2.5 to 30 microns. Infrared radiation materials can be specifically described in the patent CN 104106197 The polymer clay nanocomposite, or better, can use tourmaline, namely cyclic silicate mineral.

The infrared radiation material is mixed and distributed in the insulating base material in the form of powder. The mixed wire coating material may contain between 0.05% and 8% by weight of infrared radiation material. Preferably, the infrared radiation material may be less than 0.3 The average particle size of the micron powder particles, and the smaller powder particle size enables the infrared radiation material to have a larger surface area under the same weight, thereby fully exerting the ability to emit infrared light. When the infrared radiation material is mixed in the insulating base material, it is mixed in the form of powder. In order to avoid that the powdery infrared radiation material agglomerates or cannot be uniformly dispersed during the mixing into the insulating base material, the infrared radiation material can be ground to 50 to 150 Nanometers are further modified with ceramic materials in advance, and finally powders with a particle size of less than 0.3 microns are obtained to facilitate the uniform distribution of infrared radiation materials in the insulating base material.

The particle size of the infrared radiation material is preferably less than 0.3 microns, which can be easily applied to various plastic injection or plastic extruders. However, in the case of suitable processing methods, the infrared radiation material powder is changed to greater than 0.3 Those with a particle size of micrometers are no exception.

In this way, since the wire core in the above-mentioned wire is covered by the wire coating material, the infrared radiation material in the wire coating material will be distributed around the wire core. When the wire is heated due to the power consumption of the current-carrying current, it even generates heat. When the harmonic pollution causes vibration, it will cause infrared radiation materials such as tourmaline powder to radiate infrared rays. By irradiating the core of the wire with infrared rays, the impedance of the conductor will be reduced, and the additional power consumption caused by harmonic pollution will be reduced.

Secondly, when the infrared radiation material uses tourmaline, due to the spontaneous polarization of tourmaline, a weak electric field will be generated around the wire core, which can reduce the overall inductance of the wire, increase the response speed of current fluctuations, and make the current carry The impedance received is reduced, which in turn can reduce the power loss in the wire.

Using the above-mentioned wire coating materials and wires, users can use the wires directly in the conductive lines of the power grid, or they can also be used in the windings of transformers or motors, which can reduce the power loss of the wires and obtain energy-saving use effects. It also reduces the calorific value of wires, slows down the aging of wires and related devices, and increases the service life of wires and electrical appliances.

The above-mentioned wire coating materials and wires can be applied not only to the transmission and distribution network of the commercial power grid, but also to equipment with independent power systems, such as automobiles and electric vehicles, which can also reduce the power loss of the power system in the vehicle and improve The energy efficiency of the equipment has the effect of energy saving.

To sum up the above description, the wire and insulating sheath provided by the present invention can reduce the power loss in the power grid or the power system, resulting in energy-saving use effects, and after the power loss is reduced, the heat generation of the power system itself can also be reduced, which can increase the wire And the service life of related equipment, at the same time reduce the abnormal problems caused by overheating of the power system, and have the characteristics of energy saving and environmental protection, prolonging the service life of electrical devices and improving safety, which are beneficial to energy saving and power related industries and consumers.
