[Problems to be solved by the device]

  The articles on electromagnetic waves are intended for those generated from electrical equipment itself. It is possible to intuitively feel that electromagnetic waves are being generated from this electrical device. It However, when the inventor measured electromagnetic waves, As expected, electromagnetic waves are emitted, but not only these electric devices, Electric cords connected to indoor electrical wiring and equipment, carpet heaters for heating -Or a small amount from the heater of electric equipment It has been certified.

[0005]   Therefore, the computer and the wires connected to it are If you are exposed to electromagnetic waves while living on your side for a long time, the electromagnetic waves are weak However, it can be understood that the effect cannot be ignored. Also, like the microwave For electrical devices that can be visually inspected, be careful while keeping a certain distance. By living in such a way, it is possible to prevent radiation of electromagnetic waves considerably.

[0006]   However, it is connected to electrical wiring, cooking equipment, and household appliances that are close to the body Use an electric cord, carpet heater for heating, or electric floor heating equipment to It is extremely difficult to live away from something that does not have a shield function.

[0007]   Therefore, even weak electromagnetic waves generated from electric wiring or electric cords are possible. It is important to reduce as much as possible.

[0008]   In the case of an electric floor heating system, a sheet heater is laid inside the floor structure, Since the child has the opportunity to play and lie down, Considering the influence of the electromagnetic wave generated from the planar heater of When measured, there is a difference depending on the product and the place of measurement It was found that an electromagnetic wave of 100 to 180 milligauss was generated.

[0009]   Therefore, one of the inventors of the present invention has proposed an electric floor heating system using this sheet heater. A method of erasing magnetic waves has been developed and previously proposed (Japanese Patent Application No. 2002-352877).

[0010]   This device prepares two sheet heating elements with the same characteristics and stacks them. At the same time, the AC power of the power supply unit is applied so that currents may flow in opposite directions to the two sheet heating elements. By connecting to the heat source and adjusting the mutual position of the two sheet heating elements. It is to eliminate the waves.

[0011]   The present invention applies the technical idea of the above invention to a power conductor made of a filament conductor. It was obtained as a result of studying the above and is a line that does not generate electromagnetic waves during energization. A power conductor made of a strip conductor, that is, a device intended to provide a special electric wire Is.

[Embodiment of device]

  Next, an embodiment of the present invention will be described with reference to the drawings.

[0017] (First embodiment)   FIG. 1 shows a cross-sectional shape of a basic electric power conductor (special electric wire) of the present invention. A pair of conductors 2a and 2b (first conductors) each having an insulating coating h, and 3a 4 conductors composed of another pair of conductors (2nd conductor) 3b are arranged in a cross shape. Bundled together and covered with a circular tubular insulation coating 4 A cable-shaped power conductor 1 is configured.   This power conductor 1 has a plurality of spaces S in its structure, which is a single-phase power source. It has a four-core structure in which two wires are united.

[0018]   When the power conductor 1 is used by wiring it to a house or an electric device, the conductor 2a Is the positive electrode, the conductor 2b is the negative electrode. In addition, the conductor 3b adjacent to the conductor 2a In the negative electrode, the conductor 3b and the conductor 3a adjacent to the conductor 2b are connected to the positive electrode. is there. In other words, two cores of the four cores are positive electrodes and the other two cores are negative electrodes. It is a condition that the same polarities are arranged symmetrically with respect to each other. And supply power When the polarities of the two pairs of conductors are reversed, The wiring is such that the generated electromagnetic waves cancel each other and are erased.

Cables and a pair of power conductors or a pair of heat conductors It is premised that it is used. The two pairs of conductors are It is premised that the conductors have different polarities.

[0029]   Figure 7 shows the terminal part (connector). The terminal 10 is formed with a total of four poles, with the positive pole having two poles and the negative pole having two poles. Well In addition, the terminal 11 on the load side has two positive electrodes from the terminal 10 side. And two negative electrodes are combined to form a terminal having a pair of electrodes.

[0030]   In short, the power supply side is supplied in a single phase, and the power conductor 1 has two pairs of single phase conductors. Since it is configured as one cable with the arrangement of, it can be supplied as a single phase on the load side. Or a pair of positive electrodes of two conductors on the load side.
