Abstract
The utility model relates to wire material for the electrical engineering aspect, which can be made into the wire in the shape of trapezoid or in the shape of arc approaching to the trapezoid; a stranded wire (cable) made of trapezoid metallic wire material is applied, compared with the prior art, the overall diameter can be reduced by 10 percent to 15 percent, the gross sectional area can be reduced by 20 percent to 30 percent, the spatial utilization rate can reach 98 percent, and the use cost can be obviously reduced. When a slip type press adjusting transformer is wound particularly, lead wires can be tightly and smoothly arranged and does not use machinery grinding, metal is saved, and process step is reduced. The utility model has the advantages of high work efficiency, and energy saving.
Description
The utility model belongs to the metal wire rod of a kind of electrician aspect.
At present both at home and abroad aspect the electrician its section of employed metal wire rod be round wire and rectangular lines.The wire rod of these two kinds of structures uses to feel it is inappropriate sometimes under all occasions.Especially ought be used in and scratch the system variable resistor, slidingtype voltage regulating transformer and power transmission and transformation cable or the like, all exist processing and manufacture complexity, waste of material, shortcomings such as electric energy loss is big, as, when manufacturing the slidingtype voltage regulator that ring winding distributes, in order to increase the contact-making surface area, superficies with the voltage regulator coil of its round conductor coiling, through one grinding process, grind off the 15～25%(that is equivalent to the round conductor section and see accompanying drawing 1), thereby strengthened the current density of outermost layer lead significantly, temperature rise, increase energy consumption, lower efficiency, wasted metal, more distinct issues are, effective wide slit between lead, cause powdered carbon and metal powder to be detained, form the spark future trouble.And for example, stranded wire (cable etc.), because the ectonexine lead is around on the contrary, the twisted wire overall diameter is the diameter sum (seeing accompanying drawing 2) of each layer line, and at this moment because the space availability ratio low (64～80%) that cause in the space between lead, and volume is bigger than normal, cause the packing of non-bare wire to apply glue or armoring material waste 10～30%, big because of volume during stringing in the open air, so wind resistance and vibration are increased thereupon, the Surface Groove deposition is too much or the like.
The purpose of this utility model provides a kind of coiling variable resistor that is used in, voltage regulating transformer and easy to use when manufacturing special purpose such as power transmission and transformation cable, the metal wire rod of its section approximate trapezoid.
This trapezoidal metal wire rod is achieved in that it can be made by metals such as copper, aluminium, iron, and the cross section of this line is the arc wire rod of trapezoidal or approximate trapezoid.Be that the wire rod section is to can be made into linear or arcuate structure in the trapezoidal upper and lower end, be beneficial to annular coiling and manufacture power transmission and transformation cable etc.
Accompanying drawing 1 is the sectional schematic diagram that existing circular metal line is manufactured voltage regulator.
Accompanying drawing 2 is sectional schematic diagrams of existing circular twisted wire (cable).
Accompanying drawing 3 is sectional schematic diagrams that the utility model is used for doing voltage regulator.
Accompanying drawing 4 is sectional drawings that the utility model is used for doing twisted wire (cable).
Accompanying drawing the 5, the 6th, structural representation of the present utility model.
Find out with reference to accompanying drawing 3,4,5,6, four angles of this kind wire rod section are blunt slightly, the upper and lower end of trapezoidal cross-section, can be linear or arc, the size of its radian, and section structure determining dimensions can be made the physical dimension of different size according to purposes and technological requirement, to satisfy user's instructions for use, in order not change technological requirement and the technical specification that has with each product of round wire processing, generally speaking, section structure size (with reference to accompanying drawing 3) is: the length L at the high 1/2h of trapezoidal waist place
rDiameter d=the 2r that is equivalent to the circle line, i.e. L
r=2r, and the relation of height h and round conductor is: h=0.8L
r=1.6r, when the shared angle [alpha] of wire rod one regularly, on the relation of going to the bottom with height and radius be:
(L
1)/(L
2) ＝1－ (h)/(r) 。
Use this wire rod, the pair twist zygonema, overall diameter reduces 10～15% than originally, total cross-sectional area reduces 20～30% than original, and space availability ratio reaches 98%, volume-diminished 1/5～1/3, the packaging material of non-bare wire reduce about 20%, have obviously reduced cost. Can make the compactness of arranging between lead, level and smooth during especially to coiling slidingtype adjustable transformer, almost not have groove or slit between line, not need to carry out again mechanical grinding, save metal, reduce operation. Owing to do not lose the effective area of lead, thereby current density is constant, has reduced temperature rise, has improved efficient, has saved electric energy.
Claims (1)
1, the metal wire rod used of a kind of electrician aspect, it can be made by copper, aluminium, iron, and it is characterized in that: the cross section of this line is the arc wire rod of trapezoidal or approximate trapezoid, and promptly the wire rod section is to can be made into linear or arcuate structure in the trapezoidal upper and lower end.
