Description

  • [0001]
    Die Erfindung betrifft ein konzentrisches Dreileiterkabel, insbesondere für Ultraschallmessungen, mit einem Innenleiter und Außenleitern aus geflochtener Litze, die voneinander und von dem Innenleiter durch Isoliermaterial distanziert sind. The invention relates to a concentric three-core cables, in particular for ultrasonic measurement, with an inner conductor and outer conductors of braided strands that are distanced from one another and from the inner conductor by insulating material.

    Weil vor allem in Kernkraftwerken im Hinblick auf kurze Stillstandszeiten bei wichtigen Prüfungen mit Ultraschall gleichzeitig Reparaturarbeiten stattfinden, die mit Funksprechverkehr verbunden sind oder Lichtbogenschweißen erfordern, ergeben sich recht starke elektrische und/oder elektromagnetische Störfelder. Because at the same time take place primarily in nuclear power plants in terms of short downtimes in important tests with ultrasound repairs that are connected to radio traffic or require arc welding, there are very strong electric and / or electromagnetic fields. Sie hatten bisher oft zur Folge, daß trotz der Verwendung der oben genannten Dreileiterkabel die Ultraschallprüfungen wegen Störspannungen unterbrochen und zum Beispiel in die Nachtzeiten verlegt werden mußten. yet they often had the consequence that despite the use of the above three wire ultrasonic tests had to be interrupted due to interference voltages and routed for example in the night hours. Deshalb geht die Erfindung von der Aufgabe aus, durch eine besondere Ausbildung des Kabels die Einkopplung von Störspannungen zu verringern, die Ultraschallmessungen beeinträchtigen können. Therefore, the invention is based on the task of reducing interference from voltages by a special design of the cable can affect the ultrasound measurements.
  • [0003]
    Gemäß der Erfindung ist bei einem Kabel der eingangs genannten Art vorgesehen, daß die Außenleiter jeweils aus mehreren Schichten bestehen und daß ihr Gleichstromwiderstand mehrfach kleiner als der des Innenleiters ist. According to the invention there is provided in a cable of the type mentioned, that the outer conductor consist of several layers and that its DC resistance is several times smaller than that of the inner conductor.
  • [0004]
    Das neue Kabel hat eine extrem hohe Koppeldämpfung. The new cable has an extremely high coupling loss.
  • [0005]
    Es ist somit unempfindlich gegen die vorgenannten Störeinflüsse. It is therefore not affected by the aforementioned interference. Dennoch kann es mit kleinem Durchmesser und guter Flexibilität ausgebildet werden, wie eingehende Erprobungen gezeigt haben. Nevertheless, it can be formed with a small diameter and good flexibility as demonstrated in-depth testing.
  • [0006]
    Das Widerstandsverhältnis zwischen Außenleitern und Innenleiter kann vorteilhaft 1:5 oder mehr betragen und übersteigt damit erheblich die Werte üblicher Meßkabel, die eine kleinere Koppeldämpfung haben. The resistance ratio between the external conductors and the inner conductors may advantageously be 1: 5 or more, and thus considerably exceeds the values ​​of conventional test leads, having a smaller coupling loss. Dabei sollte der dem Innenleiter benachbarte Außenleiter drei oder mehr Schichten aus geflochtener versilberter Kupferlitze umfassen, die zur Erzielung eines hohen Bedeckungsgrades gegeneinander versetzt sind. In this case, the inner conductor adjacent to the outer conductor of three or more layers of braided silver-plated copper wire should include that are offset from each other to achieve a high degree of coverage. Man erreicht damit trotz des erwünschten hohen Bedeckungsgrades eine gute Flexibilität. This achieves a good flexibility despite the desired high degree of coverage.
  • [0007]
    Die Litze des äußeren Außenleiters besteht dagegen vorzugsweise aus versilbertem Stahlkupferdraht, insbesondere in zwei oder mehr Schichten. In contrast, the strand of the outer external conductor is preferably made of silver-plated steel copper wire, in particular in two or more layers. Man erreicht damit neben einer elektrischen Abschirmung auch noch eine direkte magnetische Abschirmung, ohne daß die Flexibilität wie bei anderen stahlbewehrten Kabeln beeinträchtigt ist. thus, can be reached next to an electrical shield also a direct magnetic shield without the flexibility is deteriorated as with other steel reinforced cables. Dennoch wird auch eine hervorragende mechanische Widerstandsfähigkeit gegen rauhen Betrieb erreicht. Nevertheless, an excellent mechanical resistance is achieved against harsh conditions.
  • [0008]
    Das Isoliermaterial kann in bewährter Weise aus Polytetrafluoräthylen bestehen, wobei die Dicke zwischen Innenleiter und erstem Außenleiter abhängig ist von dem geforderten Wellenwiderstand des Kabels. The insulating material may consist in a proven manner of polytetrafluoroethylene, wherein the thickness between the inner conductor and the first outer conductor is dependent upon the required characteristic impedance of the cable. Als äußerer Schutz empfiehlt sich ein Mantel mit annähernd der gleichen Dicke wie das Isoliermaterial. As an outer protective sheath a recommends having approximately the same thickness as the insulating material. Er besteht zweckmäßig aus Polyurethan, das eingefärbt sein kann, um das Kabel auffälliger zu machen oder zu kennzeichnen. He is expediently composed of polyurethane, which can be colored to make the cable striking or mark.

    Der Aufbau des neuen Triaxkabels mit extrem hoher Koppeldämpfung bei kleinem Durchmesser ( v 6 mm) und guter Flexibilität sowie robuster Ausführung wird in Richtung von innen nach außen beschrieben. The structure of the new Triaxkabels with extremely high coupling loss in small-diameter (v 6 mm) and good flexibility and robust design is described in the direction from inside to outside. Das Kabel besteht aus einem Innenleiter 1 aus Cu-Litze 7 x 0,18 versilbert, dh sieben Kupferdrähten mit 0,18 mm Durchmesser, die versilbert und miteinander verdrillt sind. The cable consists of an inner conductor 1 made of copper wire 7 x 0.18 silver, ie seven copper wires of 0.18 mm diameter silver-plated and are twisted together. Der Gleichstromwiderstand ist 100 mΩ/m. The DC resistance is 100 milliohms / m.
  • [0011]
    Das nachfolgende Dielektrikum 2 besteht aus hochisolierendem Material, nämlich Polytetrafluoräthylen, das auf den Innenleiter 1 extrudiert ist. The subsequent dielectric 2 consisting of highly insulating material, namely polytetrafluoroethylene, which is extruded onto the inner conductor. 1 Dem Außendurchmesser von 1,7 mm entspricht eine Isoliermaterialdicke von etwa 0,6 mm. The outer diameter of 1.7 mm corresponds to a Isoliermaterialdicke of about 0.6 mm. Man erhält damit einen Wellenwiderstand von ca. 50 Ohm. so as to obtain a characteristic impedance of 50 ohms.
  • [0012]
    Die innere Abschirmung 3 umfaßt drei übereinander geflochtene Schirme, die aus versilberter Kupferlitze bestehen. The inner shield 3 comprises three superposed braided screens which consist of silver-plated copper wire. Die Kupferlitze ist in mehreren, zum Beispiel 16 Schlägen von mehreren, zum Beispiel 5 oder 6 Leitern mit 0,1 mm Durchmesser zu einem spitzwinkligen Geflecht versponnen. The copper wire is spun from several, for example 5 or 6 conductors with 0.1 mm diameter to a braid in the acute-angled more, for example 16 beats. Insgesamt ergibt sich für die Abschirmung 3 ein Außendurchmesser von 3,0 mm und ein Gleichstromwiderstand von 12 mΩ/m. Overall, for the shield 3, an outer diameter of 3.0 mm and a DC resistance of 12 milliohms / m. Durch diese mehrfachen Abschirmungslagen wird ein sehr guter Bedeckungsgrad bei guter Flexibilität erreicht. Through these multiple layers of shielding a very good coverage is achieved with good flexibility.
  • [0013]
    Der Innenabschirmung 3 folgt eine zweite Isolation 4. Sie besteht ebenfalls aus extrudiertem Polytetrafluoräthylen und hat einen Außendurchmesser von 3,8 mm. The inner shield 3 is followed by a second insulation 4. It also consists of extruded polytetrafluoroethylene and has an outer diameter of 3.8 mm.
  • [0014]
    Der Außenschirm 5 des Triaxkabels besteht aus zwei übereinander geflochtenen Schirmen aus versilbertem Stahlkupferdraht, die ebenfalls einen guten Bedeckungsgrad erreichen lassen. The outer shield 5 of the Triaxkabels consists of two superimposed braided shield of silver-plated steel copper wire, which can also achieve good coverage. Dabei sind jeweils 24 Schläge von 5 bzw. 6 Einzelleitern mit 0,13 mm Durchmesser spitzwinklig miteinander versponnen. In each case, 24 strokes of 5 or 6 individual conductors of 0.13 mm diameter are spun together at an acute angle. Dies ergibt einen Außendurchmesser von 5 mm und einen Gleichstromwiderstand von 17 mΩ/m. This results in an outer diameter of 5 mm and a DC resistance of 17 milliohms / m.
  • [0015]
    Der äußere Mantel 6 besteht aus Polyurethan. The outer sheath 6 is made of polyurethane. Er ergibt den Außendurchmesser von 6 mm. He gives the outer diameter of 6 mm.
  • [0016]
    Der entscheidende Vorteil der Erfindung liegt in der extrem hohen Koppeldämpfung von > 140 dB des Kabels. The decisive advantage of the invention lies in the extremely high coupling loss of> 140 dB of the cable. Erreicht wird dies durch die Anwendung mehrschichtiger Schirme, die einen hohen Bedeckungsgrad bei gleichzeitig niedrigem Längswiderstand und großer Flexibilität ermöglichen. This is achieved through the application of multi-layer screens that allow a high degree of coverage with a low series resistance and high flexibility.
  • [0017]
    Die Schirmwirkung bezieht sich nicht nur auf elektrische Felder, sondern infolge der Verwendung von Stahlkupfer im äußeren Schirm durch magnetostatische Wirkung auch auf magnetische Felder. The shielding effect applies not only to electric fields, but due to the use of copper in the steel outer shield by magneto-static effect on magnetic fields. Das Kabel ist daher nicht nur bei Ultraschallmessungen sondern auch in der Datentechnik zur Verringerung der Störempfindlichkeit mit Vorteil einsetzbar. The cable is therefore used to advantage not only in ultrasound measurements but also in data technology to reduce noise sensitivity.
