Description
Anordnung mit aus Schalen-oder Topfkernspulen bestehenden Pupinspulen.
Es ist bekannte das in den für die Aufnahme von Pupinspulen von Fernmeldekabeln
bestimmten Kästen und Muffen oder dergl. kapazitive und magnetische Kopplungen auftreten,
die von den
Bei der aus Schalen-oder Topfkernspulen bestehenden, in Spulenkosten
oder dergl, eingebauten Pupinspulenanordnung nach der Neuerung sind auf jede Spule
mit dem Kern in Berührung stehende Abschirmungen zum Beispiel Metallkappen aufgebracht
und die Abschirmungen nicht geerdet bzw. nicht mit dem Spulenkasten leitend verbunden.
Gemäss einer Weiterbildung der Neuerung sollen die Abschirmungen von zu einem Vierer
gehörigen Pupinspulen untereinander leitend verbunden werden. Die Nichterdung der
Abschirmung bei der Anordnung nach der
Die abgeschirmte Spule oder mehrere, zum Beispiel die zu einem Vierersatz
gehörigen Spulen, können in einer nicht dargestellten
Die sich bei Weglassung der Erdung der Kappen einstellenden Verhältnisse
seien nachfolgend am Vierer betrachtet, Bei der in Figur 2 dargestellten Anordnung
werden die Kerne der drei Spulen eines Vierersatzes über die Schirmkappen leitend
miteinander verbunden, so dass die Kapazitäten Wicklung/Kern-Kappe zu den Leitern
a, b, c, d des Vierers in der Anordnung als vierstrahliger Stern auftreten. Die
Differenzen der Kapazitäten gegen die Kerne werden dann in der kapazitiven Mitsprechkopplung
im halben Betrage miterfasstund gehen ebenso in die ilitsprech-
Ferner karfisich auch in der Fremdbeeinflussung durch die freie Potentiallage der miteinander verbundenen Kerne eines Viererspulensatzes wegen der Kleinheit und Gleichheit der Kapazitätswerte keine Ausbildung von Störströmen ergeben.Furthermore, there is also an external influence due to the free potential position of the interconnected cores of a four-coil set because of their small size and Equal capacitance values do not result in the formation of interference currents.
Bei Stammspulen kann es zweckmäßig sein, die Verhältnisse des Spulensatzes
nachzubilden, indem je zwei Spulen zusamnengefasst und ihre Kerne über die magnetischen
Schirmteller verbunden werden. Durch den so wiederum erhaltenen Viererstern kann
dann zum Beispiel ein etwa bei der Montage auftretender Schluss Wicklung/Kern, der
sich auch bereits durch einen höheren Erdkopplungswert zeigen würde, mittels der
Mitsprechkopplungsmessungen genau erfaßt werden 3 Figuren
