Description

[Detailed description of the invention] This poor strength is due to the arc-resistant tube 4i that does not cause -m qJ, even if it receives arcs due to flash flashes, cross-circuits, short circuits, etc.
It concerns four turtle bodies consisting of Peng's twisted eyelids.

When an arc is generated in the vicinity of the merging point of a conductive material made of a metal twisted eyelid such as a combed eyelid, the heat of the arc causes the erosion that makes up the twisted eyelid to take a bath. In addition, poor twisting may melt and cause an accident.

In order to prevent such a break, conventionally a so-called armor rod is wrapped around the surface of the monument body near the Jinshi point to keep the mh body from the arc. However, the armoured of this armor rod was about 2m behind, and it was difficult to completely protect the monument's body at this extreme level.

In addition, there are almost no measures to protect conductors from arcs caused by phase-to-phase short circuits in W&
It was 4, which consisted of just one overhead ground wire to increase heat resistance.

This Akio was made in view of the above circumstances, and the heat of the arc causes melting damage to the IL tower and the aerial birch, and the fgw
The purpose of the present invention is to provide a conductive body made of twisted gold LF4 with excellent arc resistance that reliably prevents damage to the outer surface of at least the twisted strands of each of the twisted strands constituting the metal twisted touge. When going out, there is a high quality material on the surface of the stock,
It is characterized by a tentative layer of material having a high heat of fusion.

Hereinafter, this invention will be explained in detail with reference to the drawings.

FIG. 1 shows the first ㅅj of the conductor of the present invention, and the reference numeral 1 in the figure indicates a four-gauge body according to the present invention. This 4I
The IL body 1 is made by twisting together a plurality of masticates (7 in this case) made of materials such as aluminum, aluminum alloy, whip, etc.
W4 is also made of a certain material and is further provided with a coating (hereinafter abbreviated as protection test) 3 made of a material with high heat resistance. That is, by forming a temporary sandalwood 3 on the surface of each masticating material 2 and combining several bubbles of the element 2 on which the masticating coating 3 has been formed, the conductive material made of the gold twisted material of the present invention can be obtained. Body 1 is the one to be served.

The materials that make up Jokihosho 6+13 are:
When the wood assembly 2 is aluminum or an aluminum pot, for example, silicon, copper, crab, gold, cobalt, chromium, iron,
Germanium, molybdenum, niobium, nickel, palladium, platinum, rhenium, tantalum, thorium, titanium,
Melting points (m, p) of metals such as tungsten and zirconium, oxides such as silica, alumina, zirconia, and magnesia, salts such as calcium chloride, acid calcium, potassium chloride, sodium chloride, barium chloride, etc.9

Gold such as palladium, platinum, rhenium, tantalum, thorium, titanium, vanadium, tungsten, zirconium, etc., 5nOa2. Alloys such as AlSb, oxides such as quartz, silica, alumina, magnesia, zirconia, oxidized steel, aluminum fluoride, calcium fluoride, calcium sulfate, steel sulfide, magnesium heptadide, strontium fluoride, potassium phosphate, I ! When the acid point (m, p) of a salt such as ilt acid lead is more than 135'7°, the heat of fusion C

Methods for coating the strands 2 with materials for such plates include vapor deposition, plating, and bath-side methods when the material to be welded has self-shape properties such as metals and their alloys. , sputtering method, CVD method, P, /D method, etc. are used, and the materials used are salt and gold! ! In the case of a material with low self-shape retention such as a 1eIk compound, a resin such as a thermosetting resin or thermosetting resin is used as a binder to improve the layering properties on the eraser shape and the material 2. Give and hold - form temporary &3.

41 bodies IFi made of Kinne twist obtained by twisting the base 2 which formed such a storage 9 handling memory 3, and this was sent to aS.
If it is installed as a T or an overhead ground wire, even if it receives an arc from Tsurunei etc., the material forming the protective plate $3 on the surface of the base #2 will have a lower heat of fusion than the base #2 itself. Therefore, the heat of the arc is consumed to evaporate the heat of the arc, and the material 2 itself is not affected by the arc heat, and the wooden group 2 is protected from the arc. That will happen. In addition, since such a protective plate 3 can be easily formed to any length in the length direction of the conductor 1, it can retain the 41 body 1 in a long range centered on the ha point where arcing is likely to occur. be able to.

FIG. 2 shows 82 vIl of this invention, the first
The same as those shown in the section - the same symbols are attached to the component parts,
The explanation will be omitted.

The conductor 1 made of gold S grade in this example is formed by forming the above-mentioned M break at 3 only on the strands 2 located in the outermost part of the collector 2 constituting the metal wire #1. It is. In this example as well, young fruits with the same effect as in the first example are obtained, and since the woodwork 2, which is not exposed on the surface, is not provided with the protective malt cover &3, the arc resistance of the conductor 1 is improved. The cost of 1 Boaki is calculated.

Note that the protective malt cover 13 may be formed over the entire length of the conductor 1, but may be formed only in the portion located near the Iri suspension point if the suspension point is determined in advance. .

As explained above, the conductor made of the golden bird pen of the present invention is applied to the surface of each element forming at least the outermost part of each wooden group constituting the metal strand. Since the spider material is coated with a material that has a high melting point and heat of fusion, even if it is subjected to an arc due to a short circuit or lightning strike, the heat of the arc will be transferred to the material coated on the masticated surface. The arc heat is consumed by melting and evaporating, and the arc heat does not act on each spider. Therefore, it is possible to reliably prevent the occurrence of accidents such as bathing or breakage of the sleep guide body due to arc heat.
