Description

Electromagnetic shielding heating wire

The present invention relates to a heating wire for shielding electromagnetic waves for shielding electromagnetic waves generated from a heating wire used as a heat source, such as electric blanket, electric blanket, electric blanket, electric cushion, electric pack (hereinafter referred to as electric heat preservative), in particular, a heating element By forming a shielding layer using an aluminum thin film and a conductive wire with an insulating layer interposed therebetween, the thickness of the heating wire is reduced, the short circuit between the heating element and the shielding layer, and the cost is reduced.

As shown in Fig. 1, when the current I flows in the conductor A, a magnetic field B is formed around the conductor A, as revealed by OERSTED or Ampere. In addition, when the current I has a certain frequency, a corresponding electric field (not shown) is formed.

At this time, the magnetic field (B) is increased as the voltage is higher, the electric field is increased as the current flows, the magnetic field (magnetic wave) and the electric field (electromagnetic wave) is called an electromagnetic wave.

Therefore, when a current flows in the conductor, electromagnetic waves are inevitably generated, and the generated electromagnetic waves randomly stimulate the blood of the human body to interfere with the flow of air, resulting in a blood circulation disorder. In addition, the fatigue is aggravated, of course, in severe cases, such as causing a stroke, and there was a problem that causes noise and malfunction in other electrical equipment.

In other words, the electromagnetic waves generated by electricity destroy biorhythms, which are difficult to detect by mechanical mechanical measuring instruments. Since the human body does not have natural electromagnetic waves that are compatible with these electromagnetic waves, the electromagnetic radiation range of electrical equipment It has an adverse effect on the nervous system of the person as it exists, which causes the living cells of the body to be destroyed, causing various dermatitis and headaches, chronic fatigue, menstrual irregularities, premature birth, birth defects and paralysis, as well as television, audio, and video. There have been problems such as being a noise source causing noise and malfunction in various electrical equipment.

In particular, when the electromagnetic wave generating source (conductor, various electrical equipment) is located in close proximity to the human body, the damage is serious.

Representative examples of the electromagnetic wave source used in close proximity to the human body is an electrothermal insulator.

Accordingly, many studies have been conducted to remove electric and magnetic fields generated from heating wires used as heat sources of heat preservation heaters.

In general, the most effective method of removing the electric field is to completely shield the electric field generating source (conductor, heat insulation, various electrical equipment, etc.) with a conductor, and then completely connect the conductor to the ground to connect the conductor to the conductor. The discharge of the induced electric field (electromagnetic wave, electric charge) to the ground, the most effective way to remove the magnetic field is to block the external emission of the magnetic field by completely shielding the magnetic field source with a high permeability metal body.

However, if the heating wires, which are the source of electromagnetic waves, are distributed over a large area, such as a heat insulator, the entire heat insulator is completely covered with a conductor to remove the electric field, or the entire heat insulator is highly permeable to remove the magnetic field. The complete enveloping of the metal body is not practically easy due to its realization technology and cost.

Therefore, in Korean Patent Application No. 96-48224, which is a prior invention of the present invention, as shown in FIG. 2, the heating wire 1 is composed of a straight carbon glass fiber and is insulated so that the outer circumferential surface of the heating wire 1 is completely wrapped. The shielding layer 3 is formed with the layer 2 interposed therebetween, and the heating line 1 is connected to one end of the shielding layer 3, and then power is applied through the other end, thereby generating the heating line 1. The magnetic field generated in the heating wire H was canceled by making the directions of the magnetic field B 'formed in the magnetic field B' and the magnetic field B " formed in the shielding layer 3 reverse.

In addition, in Korean Patent Application No. 97-45321, which is a prior application of the present invention, when the power is applied to the heating wire H, the shielding layer 3 has a ground ground potential (that is, it is connected to the ground, or the ground ground potential is The electric field (electromagnetic wave, electric charge) induced in the shielding layer 3 to the ground or to a power ground line having an earth ground potential, or to a virtual ground point. Magnetic waves emitted from the heating wire (H) were removed.

That is, as shown in Figure 2, the carbon fiber fibers of the multi-line arranged in a straight line to form a multi-core linear heating line 1, the insulating layer 2 with silicon rubber so that the outer peripheral surface of the heating line (1) completely wrapped ), And the shielding net 3 is formed to surround the outer circumferential surface of the insulating layer 2, and after forming the outer insulating layer 4 made of the conductive cone rubber on the outer circumferential surface of the shielding net 3, By connecting one end of the shielding net 3 and the heating wire 1, and applying the power to the other end, the shielding net (3) has a ground ground potential, the magnetic field through the shielding net (3) and All electric fields were shut off.

However, in the above-described invention of the applicant's own application, when the heat preservation heater is moved (that is, folded or unfolded), the silicone rubber is scratched by the shielding network 3, so that the gap between the shielding network 3 and the heating wire 1 is reduced. There is a problem that the insulation is broken, and the heating wire (H) is thick due to the shielding net (3).

In addition, in order to prevent dielectric breakdown of the silicone rubber, the thickness of the insulating layer 2 made of the silicone rubber should be thickened. If the insulating layer 2 of the silicone rubber is thickened, the thickness of the heating wire becomes thicker. As well as lowering, there is a problem that the price is increased due to the use of expensive silicone rubber.

An object of the present invention is to solve the conventional problems as described above, in particular, by forming a shielding layer with an aluminum thin film and at least one wire wound around the aluminum thin film, thereby preventing the destruction of the insulating layer made of silicon rubber At the same time to provide a "electromagnetic shielding heating wire" that can reduce the thickness of the heating wire and reduce the cost.

Another object of the present invention, after forming the shielding layer through the aluminum thin film and the conductive wire, the insulation between the heating wire and the shielding layer is insulated using two thin insulating layers, thereby preventing destruction of the insulating layer And, to reduce the thickness of the heating wire, and to provide a "electromagnetic shielding heating wire" that can reduce the production cost.

Configuration 1 of the present invention "electromagnetic wave shielding heating wire" to achieve the above object is a heating wire for arranging one or more linear heating elements in a straight line to form a single-core or multi-core linear heating element; An inner insulating layer formed to surround an outer circumferential surface of the heating wire; A shielding layer comprising an aluminum thin film formed to surround an outer circumferential surface of the insulating layer and at least one conductive wire wound around the aluminum thin film; It is characterized by the technical configuration that the outer circumferential surface of the shielding layer is configured to include an outer insulating layer formed to surround.

In addition, the heating wire is characterized in that the carbon glass fiber.

In addition, the inner insulation layer, or the outer insulation layer is characterized in that formed of silicon rubber or Teflon.

Configuration 1 of the present invention "electromagnetic wave shielding heating wire" is configured to form a shielding layer through a soft and tough aluminum thin film and one or more conductive wires wound thereon, thereby preventing the destruction of the internal insulating layer due to pressing and the like. This will reduce the thickness of the heating wire.

The reason why the shielding layer is formed by using the aluminum thin film and the conductive wire is that the shielding film is formed using the large area of the aluminum thin film whose resistance component is smaller than that of the conductive wire (covering the outer circumferential surface of the heating wire), and the conductive wire connected to the aluminum thin film is formed. This is for conducting current.

In other words, the aluminum thin film is smaller in resistance than the conductive wire, but the thickness thereof is so small that it is difficult to conduct a current to operate the heating wire, and the conductive wire can conduct a sufficient amount of current, but there is no area to cover the entire heating wire. When the wire is wound on the aluminum thin film, the electric field generated from the heating wire can be shielded by using a large area of the aluminum thin film having almost zero resistance, and the voltage drop due to the electric field can be minimized. It can be minimized, it is possible to conduct a sufficient amount of current using the wire.

On the other hand, the configuration 2 of the "electromagnetic wave shielding heating wire" comprises: a heating line for arranging at least one linear heating element in a straight line to form a single-core or multi-core linear heating element; A first insulating layer formed to surround an outer circumferential surface of the heating wire; A second insulating layer formed to surround the outer circumferential surface of the first insulating layer; A shielding layer comprising an aluminum thin film formed to surround an outer circumferential surface of the second insulating layer, and at least one conductive wire wound around the aluminum thin film; It is characterized by the technical configuration that the outer circumferential surface of the shielding layer is configured to include an outer insulating layer formed to surround.

In addition, the heating wire is characterized in that the carbon glass fiber.

The first insulating layer may be Teflon, and the second insulating layer may be Kapton insulating paper.

Configuration 2 of the present invention "electromagnetic wave shielding heating wire" has a thickness reduction effect, an insulation reinforcement effect, an insulation breakdown effect, and a cost reduction effect in addition to the characteristics of the configuration 1 There is.

That is, the first insulating layer made of expensive Teflon is formed with a minimum thickness to maintain the insulating properties, and the second insulating layer is inexpensive, has good heat resistance, slippery surface, and uses tough and excellent Kapton. By forming, it is possible to reduce the thickness of the heating wire, to strengthen the insulation, to prevent breakdown, and to reduce the cost.

Hereinafter, with reference to the embodiment according to the technical idea of the present invention "electromagnetic wave shielding heating wire" configured as described above in detail the configuration, operation and effect.

Example 1

Embodiment 1 is an embodiment of the configuration 1 according to the technical spirit of the present invention "electromagnetic wave shielding heating wire".

First, as shown in Figure 3, by arranging the carbon fiber of the multi-line in a straight line to form a heating line 11 which is a linear multi-core heating element, and then wrapped with silicon rubber or Teflon so that the outer peripheral surface of the smoke line 11 An internal insulating layer 12 is formed. In addition, after winding the aluminum thin film 13 so that the inner insulation layer 12 is completely wrapped, the two or three strands of conductors 14 are wound thereon to form a shielding layer, and silicon is wrapped around the outer circumferential surface of the shielding layer. The outer insulation layer 15 is formed of rubber or the like to form the heating wire H1 according to the first embodiment.

Then, the shielding layer made of the aluminum thin film 13 and the conductive wire occupies a smaller volume than the shielding layer formed of the conventional network, thereby reducing the thickness of the heating wire, and also destroying the internal insulating layer 12 due to the aluminum thin film. It is possible to prevent, of course, thereby reducing the thickness of the internal insulating layer 12 will be described in detail the operation and effect thereof as follows.

First, the shielding layer made of the aluminum thin film 13 and the conductive wire 14, which is the greatest feature of the present invention, will be described.

As described above, in order to remove the magnetic field and the electric field by using the shielding layer of the heating wire, one side of the heating layer 11 and the same end of the shielding layer surrounding the entire heating line should be connected, and then power must be applied through the other end.

That is, first, the shielding layer should completely surround the heating line 11, and second, the current should be conducted enough to conduct thermal insulation through the heating line through a power path consisting of the heating line 11 and the shielding layer.

Therefore, in the case of the conventional shielding layer of the heating wire, in order to completely surround the outer circumferential surface of the heating wire and to conduct a sufficient amount of current, the shielding layer was inevitably formed by using a shielding network made of a conductor (conductor). In 1, the shielding film covering the outer circumferential surface of the heating wire was performed by using an aluminum thin film having a very small resistance component, and by using one or more conductive wires as the path of the current, sufficient current flowed without the shielding network. Inevitable use is excluded.

On the other hand, in order to remove the electric field by using the shielding layer of the heating wire, as described above, the resistive component of the shielding layer should be almost zero, and the resistive component of the shielding layer should be almost zero to prevent heat (voltage drop) due to the flow of current. It does not occur. Therefore, in the case of the conventional heating wire H, a shielding net having almost zero resistance is used as the shielding layer. However, in the first embodiment, an aluminum thin film 13 having almost zero resistance is connected in parallel to the conductive wire 14. Therefore, the intrinsic use of the shielding network was eliminated by making the composite resistance component of the aluminum thin film and the conductive wire become zero.

Therefore, the conventional shielding layer, which should be used as a conductor network, is constructed by using the aluminum thin film 13 and the conductive wire 14 (that is, the shielding network, which occupies a large portion of the volume of the conventional heating wire, is formed by thin film aluminum tape and thin wire). By using a), it is possible to reduce the thickness of the heating wire to 1/2 or less of the conventional level.

Here, the reason why the shielding layer is not formed using only the aluminum thin film is because, in the case of aluminum, the thickness thereof is too thin to supply sufficient current to heat the heating line 11 (regardless of how small the resistance component is) When the current conduction area is small, a large amount of current cannot be conducted). Moreover, the reason why the parallel connection between the aluminum thin film and the conductive wire by winding the conductive wire along the outer circumferential surface of the aluminum thin film is performed by using the conductive wire. In addition to flowing a sufficient amount of current, an aluminum thin film whose resistance component is close to zero is connected in parallel to the conductive wire so that its composite resistance component is close to zero, thereby making the resistance component of the shielding layer almost zero.

Here, when the aluminum thin film and the conducting wire are connected in parallel, the composition resistance component becomes zero. When the resistances of different sizes are connected in parallel, the composition resistance component is slightly smaller than the resistance value of the smaller value of the parallel connection resistance. Because it is small. Since this is well known, detailed description thereof will be omitted.

Hereinafter, another action and effect obtained by configuring the shielding layer with the aluminum thin film 13 and the conductive wire 14 will be described.

First, the aluminum thin film 13 has a smooth and sturdy surface and is not scratched or torn. Moreover, the conductive wire 14 wound on the aluminum thin film 13 also has a small portion in contact with the aluminum thin film 13. 13) is not destroyed.

Therefore, when the internal insulation layer 12 is formed, it is not necessary to consider mechanical breakdown as in the prior art, so that the thickness can be the minimum thickness for maintaining the insulation, thereby reducing the thickness of the heating wire. Therefore, it is possible to prevent the increase in cost due to the use of a thick insulating layer.

As described above, Embodiment 1 of Configuration 1 according to the technical idea of the present invention "electromagnetic wave shielding heating wire" is formed by using a thin aluminum film and a conductive wire to reduce the thickness of the heating wire, The short circuit between the shielding layer is prevented, and the cost can be reduced.

Example 2

Embodiment 2 is an embodiment of the configuration 2 according to the technical concept of the present invention "electromagnetic wave shielding heating wire".

First, as shown in FIG. 4, the carbon fiber fibers of a plurality of lines are arranged in a straight line to form a heating line 21 which is a linear heating element, and then the first insulating layer 22 made of Teflon so that the smoke line 21 is wrapped. ) And a second insulating layer 23 composed of Kapton. In addition, after winding the aluminum thin film 24 so that the second insulating layer 23 is completely wrapped, the conductive wire 25 of two or three strands is wound thereon to form a shielding layer, and the outer peripheral surface of the shielding layer is wrapped. The outer insulation layer 26 is formed of silicon rubber or the like to form the heating wire H2 according to the second embodiment.

Then, the shielding layer made of the aluminum thin film 24 and the conductive wire 25 may occupy a smaller volume than the shielding layer formed of a conventional network, thereby reducing the thickness of the heating wire. Destruction of the insulating layer 22 or the second sub insulating layer 23 can be prevented. In addition, since the thickness of the first insulating layer 22 and the second insulating layer 23 can be reduced, the thickness of the heating wire can be further reduced, and the production cost can be reduced. The explanation is as follows.

In the description of the second embodiment, since the action and effect of the shielding layer made of the aluminum thin film 24 and the conductive wire 25 are the same as those of the first embodiment, the detailed description thereof is omitted and the first insulating layer ( 22) and the operation and effects of the second insulating layer 23 are described as follows.

First, the characteristics of the first insulating layer 22 and the second insulating layer 23 will be described.

Teflon, which forms the first insulating layer 22, is expensive compared to other insulators (eg, silicone rubber, nylon thermistor, insulating PVC, Kapton, etc.), while having excellent insulation properties, heat resistance, and toughness. The Kapton forming the second insulating layer 23 is a material having a smooth surface, strong toughness, good heat resistance, and low price, while its insulating property is inferior to that of the Teflon.

Therefore, by forming the first insulating layer 22 using the Teflon and the second insulating layer 23 using the Kapton, it is possible to achieve the effect of double insulation, such as any unexpected situation (eg It is possible to maintain insulation even if the insulation layer is damaged by an external device, etc., so that any one of the two insulation layers is destroyed, the production cost is low, and the thickness of the heating element can be minimized. Will be.

In addition, when the pressing is caused by an external force, the characteristics of the Kapton is smooth, so that the pressure can be dispersed when contacting the aluminum thin film 24, thereby preventing breakdown.

As described above, Example 2 of Configuration 2 according to the technical idea of the present invention "electromagnetic wave shielding heating wire" forms a double insulating layer using Teflon and Kapton, and forms a shielding layer using an aluminum thin film and a conductive wire. By forming, it is possible to reduce the thickness of the heating wire, to prevent a short circuit between the heating element and the shielding layer, to prevent burnout of the heating wire by the external pressure, and to reduce the cost.

[Application Example]

This application example shows that the present invention "electromagnetic wave shielding heating wire" is applied to an actual electric device.

In this application example, the application of the heating wire for the configuration 1 in the configuration according to the technical idea of the present invention will be described.

Therefore, the heating wire H1 is composed of an inner insulating layer 12 which is sequentially wrapped on the outer circumferential surface of the heating wire 11 made of carbon glass fibers, a shielding layer and an outer insulating layer 15.

Here, the inner insulating layer 12 is made of silicon rubber, the shielding layer is made of an aluminum thin film 13 and the conductive wire 14, the outer insulating layer 15 is made of silicon rubber. This is the same as Example 1 above.

In addition, the heating wire (H1) according to the technical idea of the present invention is different depending on the type of power source is used for the heating wire, it will be divided into the case of using a single-phase two-wire power supply, and the case of using a single-phase three-wire power supply will be described Same as

First, as shown in Fig. 5, the AC power applied to the electric heat preservative should be subjected to the second type of grounding work on the secondary side neutral point or one terminal of the transformer combining high and low voltage. "If one side is a single-phase, two-wire 110V or 220V power supply grounded to the ground, the description will be given.

When the power applied to the heat preservation heater is a single-phase two-wire power supply, as shown in Figs. 6 and 7, the heating wire H1 connecting the heating end 11 and the same end of one side of the shielding layer is connected to the entire heat preservation heater. After evenly arranged, the heating wire 11 and the other end of the shielding layer is configured to apply power through a temperature controller (not shown).

At this time, the power line having the earth ground potential is connected to the shielding layer among the two power lines applied to the heat insulating thermostat.

Then, the direction of the current flowing through the shielding layer (more specifically, the conducting wire of the shielding layer) and the direction of the current flowing through the heating line 11 are exactly opposite, and the magnetic field formed by the current flowing through the shielding layer and the heating line The directions of the magnetic fields flowing in (11) are opposite to each other, the centers of the magnetic fields formed in the shielding layer and the centers of the magnetic fields formed in the heating line 11 coincide, and the amount of current flowing there is the same, and thus the magnetic fields formed by the shielding layer. The magnetic fields formed on the heating line 11 are canceled with each other. That is, the magnetic field of the heating line 11 and the shielding layer having the same center and the same size at opposite distances and opposite directions are mutually cancelled.

In addition, the electric field generated by the heating wire 11 is blocked by the shielding layer having a grounding earth potential, and is discharged to the ground (more specifically, blocked by the aluminum thin film, organic) to the outside of the heating wire (H1) The electric field is not emitted.

Therefore, electromagnetic waves are not generated outside the heating wire H1 by the magnetic field canceling action and the electric field shielding action.

Secondly, as shown in FIG. 8, a case where the single-sided three-wire type power supply in which neither side of both power lines of the AC power source applied to the heat preservation heater is grounded to the ground will be described.

In the case where the power applied to the heat preservation heater is a single-phase three-wire power supply, as shown in Figs. 9 and 10, after connecting the heating line 11 and the same end on both sides of the shielding layer, one of the heating lines 11 Cut two points, and apply a single-phase three-wire power supply through the cut ends.

Then, "Power connection terminal (C) (one power line) → heating line (11) → shielding layers (13, 14) → heating line (11) → power connection terminal (C) (other power line)" and "power connection terminal" (C) (other power line) → heating line 11 → shielding layers 13, 14 → heating line 11 → power connection terminal C (one power line) " Let's go.

Then, the direction of the current flowing through the shielding layer (more specifically, the conducting wire of the shielding layer) and the direction of the current flowing through the heating line 11 are exactly opposite, and the magnetic field formed by the current flowing through the shielding layer and the heating line The directions of the magnetic fields flowing in (11) are opposite to each other, the centers of the magnetic fields formed in the shielding layer and the centers of the magnetic fields formed in the heating line 11 coincide, and the amount of current flowing there is the same, and thus the magnetic fields formed by the shielding layer. The magnetic fields formed on the heating line 11 are canceled with each other. That is, the magnetic field of the heating line 11 and the shielding layer having the same center and the same size at opposite distances and opposite directions are mutually cancelled.

In addition, the electric field generated by the heating wire 11 is blocked by the shielding layer having a grounding earth potential, and is discharged to the ground (more specifically, blocked by the aluminum thin film, organic) to the outside of the heating wire (H1) The electric field is not emitted.

Therefore, electromagnetic waves are not generated outside the heating wire H1 by the magnetic field canceling action and the electric field shielding action.

On the other hand, Figure 11 and Figure 12 shows a connection method and circuit configuration that can block the electric and magnetic fields using the heating wire according to the present invention irrespective of whether the ground applied to the electric power applied to the heating warmer, the description thereof Since it is described in detail in the Republic of Korea Patent Application No. 97-45321, the invention of the earlier application, the detailed description thereof will be omitted.

In the figure, reference numerals 31 to 38 denote first to eighth contacts, respectively, and reference numerals 41 to 44 denote switches that operate simultaneously.

In addition, Figure 13 is a circuit diagram showing the configuration of the grounding device for finding the power line grounded to the ground of the two power lines applied to the heat insulator, the description thereof in the Republic of Korea Patent Application No. 98-48388 Since it is described in detail, the description is omitted.

However, FIG. 13 shows the simplest of several grounding techniques, and in addition to the grounding technique described in FIG. 13, Korean Patent Registration No. 120022, Korean Patent Application No. 97-15860, and Korean Utility Model Registration 110276, Korean Utility Model Registration No. 112814, Korean Utility Model Registration No. 112884, US Patent Registration No. 5614889, Japanese Utility Model Registration No. 110276, European Patent Application No. 95-4008413 Make sure that you can achieve that goal.
