Definitions
- the invention relates to an electrical conductor made of an aluminum alloy type AlMgSi with high current carrying capacity.
- an electrical conductor made of an aluminum alloy type AlMgSi with high current carrying capacity.
- a method for producing the electrical conductor and a busbar and a composite busbar are also a method for producing the electrical conductor and a busbar and a composite busbar.
- busbars When overhead lines are not considered fall. Mainly busbars have emerged from among the busbars an aluminum profile with a stainless steel layer as a tread for current grinding shoes enforced.
- So-called composite busbars are produced economically in the extrusion process.
- a metallic one is created under the influence of pressure and temperature Bond between the aluminum profile and the stainless steel overlay.
- the characteristic of conductor rails is the current carrying capacity. This essentially depends on the electrical resistance per unit length.
- the electric one Resistance per unit length is the product of the specific electrical Resistance multiplied by the conductor length divided by the cross-section of the aluminum profile. From this relationship it follows that for a given Aluminum profile cross section then a higher current carrying capacity or reduced electrical power losses can be achieved if a Material with improved conductivities is used. On the other hand, by tried the use of aluminum alloys with optimized guide values cross-section with the same electrical properties of the product of the aluminum profile, the aluminum operating weight and subsequently reduce material costs.
- the invention has for its object to provide an electrical conductor made of an aluminum alloy with high current carrying capacity and high mechanical strength.
- the electrical conductor should meet the following minimum requirements: tensile strenght rm 220 MPa 0.2% proof stress Rp 0.2 200 MPa strain A 5 10% Brinell hardness HB 75 elec. conductivity ⁇ 32 MS / m
- the alloy in% by weight silicon 0.4 to 0.6 iron 0.15 to 0.2 copper Max. 0.03 manganese Max. 0.05 magnesium 0.4 to 0.6 chrome Max. 0.01 zinc Max. 0.03 titanium Max. 0.02 further alloy components individually max. 0.03, total max. 0.10 and aluminum as the remainder, and that the alloy is in an outdated condition T7.
- the electrical conductor according to the invention is preferably produced in that the alloy is extruded into a profile and subsequently is swapped out to generate the outdated condition T7.
- the aged T7 condition can generally be determined by heat treatment in a temperature range of 160 to 230 ° C for a period of 5 can be reached up to 30 h. In general, one strives for productivity reasons however, minimizing the glow duration.
- the hot aging takes place preferably in one Temperature range from 165 to 175 ° C for about 19 to 21 hours.
- the profile can be quenched on the extrusion press, for example with water become.
- Conductors are extruded busbars or composite busbars.
- the characteristic values measured on a conductor according to the invention in the material state T7 are various state-of-the-art conductors made of the alloys EN AW 6101 B T6 / T7, EN AW 6060 T66 and EN AW 6063 T6 according to DIN EN 573-3 and properties compared to DIN EN 755-2.
- the material state T7 according to the invention was set by annealing at 170 ° C. for 20 h.
- material Status Rm [MPa] Rp0.2 [MPa] ⁇ [MS / m] 20 ° C EN AW 6101B T6 minute 215 minute 160 minute 30 EN AW 6101B T7 minute 170 minute 120 minute 32 EN AW 6060 T66 minute 215 minute 160 (min. 30) EN AW 6063 T6 minute 215 minute 170 (min. 30) invention T7 minute 220 minute 200 minute 32
- inventive Conductors can be busbars with the same profile geometry Voltage drops and power losses in electrical networks Reduce by around 5% without additional costs.
