Seewasserfeste Steckverbindung für den Einsatz der Potentialsonden-Viel stellenmeßtechnik Seawater-resistant plug connection for the use of potential probe multi-point measurement technology
Die Neuerung bezieht sich auf eine Steckverbindung, die die Anforderungen 5 der Viel stell enmeßtechnik mittels Potenti a'isonden in korros^en Medien erfüllt. The innovation relates to a plug connection that meets the requirements of multi-point measurement technology using potentiometers in corrosive media.
I Mit dem Potential sondenverfahren können das Entstehen und das Wachsen \ von Rissen in metallischen Strukturen kontrolliert v/erden. Auf die Struk-&idigr; tür werden Meßpole aufgebracht; die zwischen zwei Meßpolen gemessene ) Potentialänderung ist ein Maß für das Rißwachstum bzw. ein Hinweis auf I 1° eine Anrißentstehung. Die Vi el stellenmeßtechnik wird notwendig, wenn ! wichtige Strukturen (z.B. die Standstrukturen von Offshore-Ölförderinsein) I .. mit einem dichten Netz von Meßstellen überwacht werden müssen. Aus derI The potential probe method can be used to monitor the formation and growth of cracks in metallic structures. Measuring poles are applied to the structure; the change in potential measured between two measuring poles is a measure of crack growth or an indication of crack formation. The multi-point measuring technique is necessary when important structures (e.g. the base structures of offshore oil production rigs) I .. have to be monitored with a dense network of measuring points.
Vi el stellenmeßtechnik resultiert die Forderung, daß der Obergangswiderstand aller Steckverbindungen gleich sein muß und sich während der Versuchedauer nicht ändern darf; der Einsatz im Meerwasser erfordert ferner eine spezielle : Materialauswahl. Schließlich ist beim Messen mit Wechselstrom (ACPÜ-Methode) ■ darauf zu achten, daß bei der Verbindung Meßpol/Gabelstecker/Meßlsitung • keine Induktionsschleife entsteht, wodurch Störpotentiale auftreten können.Multi-point measuring technology results in the requirement that the contact resistance of all plug connections must be the same and must not change during the test; use in sea water also requires a special selection of materials. Finally, when measuring with alternating current (ACPÜ method) , care must be taken that no induction loop is created at the connection between the measuring pole/fork plug/measuring line, which could cause interference potentials.
Bisher wurden die Meßpole schweißtechnisch auf die zu prüfenden Strukturen I aufgepunktet, die Meßleitungen v/urden angelötet. Diese Technik hat mehrere ' iiachteile: Die Lötpunkte zwischen den Meßpolen und den Meßleitungen hab&n 20 unterschiedliche Übergangswiderstände, nie sich durch Korrosion mit zunehmender Zeit verschlechtern. Ein weiterer Nachteil ist, daß die fe.-.t verlöteten Meßleitungen nicht wiederverwendbar sind.Until now, the measuring poles were welded onto the structures to be tested and the measuring leads were soldered on. This technique has several disadvantages: The soldering points between the measuring poles and the measuring leads have different contact resistances and deteriorate over time due to corrosion. Another disadvantage is that the soldered measuring leads cannot be reused.
„ Der Neuerung liegt die Aufgabe zugrunde, eine scheel" herzustellende, l· schnell lösbare und wiederverwendbare Steckverbindung zu realisieren» die"The innovation is based on the task of realizing a plug connection that can be manufactured quickly and easily and is reusable" the

in korrosiven Medien einen gleichbleibenden, niedrigen übergangswiderstand aufweist und die auch beim Messen mit Wechselstrom keine Störpotentiale durch Induktion verursacht.has a constant, low contact resistance in corrosive media and does not cause any interference potentials due to induction even when measuring with alternating current.
auf der Struktur aufgepunktet. Auf den Meßpol wird ein Gabel stecker 2, ebenfalls aus verzinnter Messingbronze, aufgeschoben. Bei jedem erneuten Aufsetzen des Gabel Steckers auf den Meßpol wird die korrodierte Oberflächenschicht des Zinns aufgerieben, so daß ein metallischer Kon- f takt genügend großen Querschnitts entsteht, um einen gleichen Übergangson the structure. A fork plug 2, also made of tinned brass bronze, is pushed onto the measuring pole. Each time the fork plug is placed on the measuring pole, the corroded surface layer of the tin is rubbed off, so that a metallic contact with a sufficiently large cross-section is created to ensure an equal transition widerstand bei einer Vielzahl von Meßstellen sicherzustellen. Die Meß leitung 3 besteht aus verzinntem Kupferdraht und ist mit strahlungsvernetztem Kunststoff isoliert, um die agressive Wirkung des im Meerwasser gelösten Sauerstoffs abzuwehren. Die Meßleitung wird mittels einer ringförmigen Lötverbindung 4, die um den Schaft des Gabelsteckers und um das abisolierte Ende des Meßdrahtes liegt, verbunden. Diese Lötverbindung 4 besteht aus einem Lotring und einem die Verbindungsstelle und den Lotring überziehenden Lötschrumpfschlauch. Das Schmelzen des Lotringes und das Aufschrumpfen des Lötschrumpfschlauches erfolgt gleichzeitig in einem ErhitzungsVorgang. Der Gabel stecker 2, die Lötverbindung 4 und das Ende der Meßleitung 3 sind mit einem zweiten Schrumpfschlauch aus strahlungsvernetztem Kunststoff umgeben, wodurch eine korrisionsverhindernde Abkapselung erreicht und gleichzeitig eine definierteresistance at a large number of measuring points. The measuring line 3 consists of tinned copper wire and is insulated with radiation-crosslinked plastic in order to ward off the aggressive effect of the oxygen dissolved in sea water. The measuring line is connected by means of a ring-shaped solder connection 4, which lies around the shaft of the fork plug and around the stripped end of the measuring wire. This solder connection 4 consists of a solder ring and a solder shrink tube covering the connection point and the solder ring. The melting of the solder ring and the shrinking of the solder shrink tube takes place simultaneously in a heating process. The fork plug 2, the solder connection 4 and the end of the measuring line 3 are surrounded by a second shrink tube made of radiation-crosslinked plastic, which achieves a corrosion-preventing encapsulation and at the same time a defined Wegführung der Meßleitung gewährleistet wird, die bei Messungen nach der ACPD-Methode die Bildung einer Induktionsschleife verhindert.The routing of the measuring cable is ensured, which prevents the formation of an induction loop during measurements according to the ACPD method.
