Description

Kondensator Es ist bel#rannt, daß Kondensatoren mit flüssigen Füll- oder Tränkungsmitteln gegen Dauerbeanspruchungen viel unempfindlicher sind als Kondensatoren mit festen @ oder erstarrenden Füllmitteln. Wenn sich nämlich ein Kondensator im Betrieb unter Stromdurchgang erwärmt und ausdehnt, wird das Tränkungsmittel zwischen den einzelnen Lagen des Kondensatorwickels z. T. herausgedrückt. Sind nun feste oder erstarrende Füllmittel verwendet, so strömt nach dem Erkalten des Kondensators, wenn dieser nicht mehr in Betrieb ist. Luft in den Kondensatorwickel nach und füllt die Stellen aus, von denen bei der Erwärmung das Tränkungsmittel verdrängt wurde. Ist dagegen der Kondensatorwickel vollständig von einem flüssigen Füllmittel umgeben, so füllt dieses die durch das Heraustreten des Trähkungsmittels entstandenen Hohlräume im Innern aus und verhindert dadurch das Nachströmen von Luft.Capacitor It is popular that capacitors with liquid filling or impregnating agents are much less sensitive to long-term stress than capacitors with solid or solidifying fillers. If there is a capacitor in the Operation under current heats and expands, the impregnant is between the individual layers of the capacitor winding z. T. pushed out. Are now fixed or solidifying fillers are used, after the condenser has cooled down, when this is no longer in operation. Air in the capacitor coil and fills the places from which the impregnating agent was displaced during the heating. If, on the other hand, the capacitor winding is completely surrounded by a liquid filler, so this fills the cavities created by the leakage of the impregnating agent inside and thus prevents air from flowing in.

Andererseits muß natürlich bei Verwendung flüssiger Füllmittel streng vermieden werden, daß Feuchtigkeit in das Gehäuse eindringen kann, was sich häufig nicht ganz vermeiden läßt. Gemäß der Erfindung sind die Nachteile etwa einjedrungener Feuchtigkeit dadurch beseitigt, daß dem flüssigen Füll- oder Tränkungsmittel, z. B. Öl, anorganische, von Kristallwasser befreite, vorzugsweise pulverisierte Stoffe, z. B. Gips, caIciniertes Kupfersulfat, beigemengt sind, die in der Flüssigkeit vorhandenes Wasser binden und unter den normalen Betriebsbedingungen des Kondensators die gebundene Feuchtigkeit nicht abgeben.On the other hand, must of course be strict when using liquid fillers can be avoided that moisture can penetrate into the housing, which is often can not be completely avoided. According to the invention, the disadvantages are somewhat more severe Moisture eliminated by the fact that the liquid filler or impregnating agent, e.g. B. Oil, inorganic, freed from crystal water, preferably pulverized substances, z. B. gypsum, caIcinierter copper sulfate, are added, which are present in the liquid Binding water and, under the normal operating conditions of the condenser, the bound Do not give off moisture.

Mengt man dem flüssigen Füll- oder Tränkungsmittel so viel wasserbindende Stoffe bei, däß eine dicke, breiförmige Masse entsteht, so erzielt man hierdurch den Vorteil, daß die Abdichtung des Kondensatorgehäuses wesentlich erleichtert wird, weil die jetzt als Füllmittel im Kondensatorg@ehäuse enthaltene salbenartige Substanz auch beim Umwenden des Kondensators nicht aus dem Gehäuse herausfließt. Verwendet man z. B. eine Mischung von Gips und Öl, so wird die etwa in dass Gehäuse eingedrungene Feuchtigkeit nicht vom 01 aufgenommen, sondern vom Gips in Form von Kristallwasser gebunden.If you add so much water-binding substances to the liquid filling or impregnating agent that a thick, pulpy mass is created, this has the advantage that the sealing of the capacitor housing is made much easier because the ointment-like substance now contained in the capacitor housing as a filler does not flow out of the housing even when the capacitor is turned over. If you use z. B. a mixture of plaster and oil so that the penetrated approximately in case moisture is not absorbed by 01, but bound by the gypsum in the form of crystal water.
