Claims (15)

  1. Elektrische Unterwassersicherung, welche dafür ausgelegt ist, in einer unter Druck stehenden Umgebung in einer druckkompensierten Umhüllung (41) betrieben zu werden, wobei die Sicherung (10) durch einen Abschnitt einer Leiterbahn (11) auf einer Leiterplatte (12) vorgesehen ist, wobei der Leiterbahnabschnitt (11) umfasst:
    - einen ersten Verbindungsabschnitt (13) und einen zweiten Verbindungsabschnitt (14) zum elektrischen Kontaktieren der Sicherung (10), und
    - wenigstens ein Sicherungselement (15), wobei das Sicherungselement (15) ein Abschnitt der Leiterbahn (11) ist, welcher einen verminderten Querschnitt im Vergleich zum Querschnitt der Verbindungsabschnitte (13, 14) aufweist, wobei das wenigstens eine Sicherungselement (15) eine elektrische Verbindung zwischen dem ersten Verbindungsabschnitt (13) und dem zweiten Verbindungsabschnitt (14) bereitstellt,
    wobei das Sicherungselement (15) dafür ausgelegt ist zu schmelzen, falls ein durch das Sicherungselement fließender elektrischer Strom einen Schwellenwertstrom überschreitet, wodurch die elektrische Verbindung unterbrochen wird, welche das Sicherungselement (15) zwischen dem ersten und dem zweiten Verbindungsabschnitt (13, 14) bereitstellt,
    dadurch gekennzeichnet, dass
    die Sicherung (10) in eine dielektrische Flüssigkeit (42) eingetaucht und mit Druck beaufschlagt ist, wobei die dielektrische Flüssigkeit einen hochohmigen Pfad für einen Lichtbogen bereitstellt, der auftritt, wenn das wenigstens eine Sicherungselement (15) schmilzt.
  2. Elektrische Unterwassersicherung nach Anspruch 1, wobei das Sicherungselement (15) eine Breite im Bereich von 0,1 bis 2 mm aufweist.
  3. Elektrische Unterwassersicherung nach Anspruch 1 oder 2, wobei der erste und der zweite Verbindungsabschnitt (13, 14) des Leiterbahnabschnitts (11) eine Breite von wenigstens 1 mm, vorzugsweise von wenigstens 3 mm aufweisen.
  4. Elektrische Unterwassersicherung nach einem der vorhergehenden Ansprüche, wobei der Leiterbahnabschnitt (11) wenigstens zwei in Reihe geschaltete Sicherungselemente (15) zwischen dem ersten und dem zweiten Verbindungsabschnitt (13, 14) umfasst.
  5. Elektrische Unterwassersicherung nach Anspruch 4, wobei der Leiterbahnabschnitt (11) ferner wenigstens einen Kühlabschnitt (18) umfasst, welcher eine elektrische Verbindung zwischen zwei Sicherungselementen (15) bereitstellt, wobei der Kühlabschnitt (18) einen Abschnitt der Leiterbahn (11) umfasst, welcher einen Querschnitt aufweist, der größer als der Querschnitt der Sicherungselemente (15) ist.
  6. Elektrische Unterwassersicherung nach Anspruch 4 oder 5, wobei die Sicherungselemente (15) im Wesentlichen dieselbe Breite aufweisen.
  7. Elektrische Unterwassersicherung nach einem der vorhergehenden Ansprüche, wobei der Leiterbahnabschnitt (11) wenigstens zwei Sicherungselemente (15) umfasst, die auf verschiedenen Seiten der Leiterplatte (12) angeordnet sind.
  8. Elektrische Unterwassersicherung nach Anspruch 7, wobei der Leiterbahnabschnitt (11) wenigstens zwei Segmente (21, 25) umfasst, die auf verschiedenen Seiten der Leiterplatte (12) angeordnet sind, wobei jedes Segment ein Sicherungselement (15) und wenigstens einen Kühlabschnitt (18) umfasst, wobei eines der Segmente (21) den ersten Verbindungsabschnitt (13) umfasst und wobei ein anderes der Segmente (23) den zweiten Verbindungsabschnitt (14) umfasst, wobei die Segmente zwischen dem ersten und dem zweiten Verbindungsabschnitt (13, 14) in Reihe geschaltet sind und wobei der Kühlabschnitt (18) eines Segments (21) auf einer Seite der Leiterplatte (12) mit dem Kühlabschnitt (18) eines benachbarten Segments (25) auf der anderen Seite der Leiterplatte (12) mittels einer oder mehrerer Durchkontaktierungen (30) gekoppelt ist.
  9. Elektrische Unterwassersicherung nach Anspruch 8, wobei der Leiterbahnabschnitt (11) mehrere der Segmente (21-26) umfasst, die abwechselnd auf gegenüberliegenden Seiten der Leiterplatte (12) angeordnet sind.
  10. Elektrische Unterwassersicherung nach einem der vorhergehenden Ansprüche, wobei jeder Verbindungsabschnitt (13, 14) ein sich verjüngendes Ende aufweist, mit dem das Sicherungselement bzw. eines der Sicherungselemente (15) gekoppelt ist.
  11. Elektrische Unterwassersicherung nach einem der vorhergehenden Ansprüche, wobei die elektrische Unterwassersicherung (10), die das wenigstens eine Sicherungselement (15) umfasst, dafür ausgelegt ist, ein Ausschaltvermögen von wenigstens 200 A bei 24 V Wechselstrom oder sogar von wenigstens 1000 A bei 690 V Wechselstrom aufzuweisen.
  12. Elektrische Unterwassersicherung nach einem der vorhergehenden Ansprüche, wobei der Leiterbahnabschnitt (11) mit einer Lötstopplack-Beschichtung zur Isolation versehen ist.
  13. Elektronische Unterwasservorrichtung, welche wenigstens eine elektrische Unterwassersicherung (10) nach einem der Ansprüche 1-12 umfasst.
  14. Elektronische Unterwasservorrichtung nach Anspruch 13, welche ferner eine druckkompensierte Umhüllung (41) umfasst, die mit dielektrischer Flüssigkeit (42) gefüllt ist, wobei die elektrische Unterwassersicherung (10) in der Umhüllung (41) in der dielektrischen Flüssigkeit (42) angeordnet ist.
  15. Elektronische Unterwasservorrichtung nach Anspruch 13 oder 14, wobei die Leiterplatte (12), auf welcher die elektrische Unterwassersicherung (10) vorgesehen ist, weitere elektronische Komponenten der elektronischen Vorrichtung (40) umfasst oder mit einer anderen Leiterplatte, die solche elektronischen Komponenten umfasst, elektrisch gekoppelt ist, wobei die elektronischen Komponenten über die elektrische Unterwassersicherung (10) mit elektrischer Leistung versorgt werden.
