Description

Die im folgenden beschriebene Anordnung ermöglicht auf einfache Weise die Steuerung eines magnetischen Schaltens, wie er z. B. für selbsttätige elektrische Wasserhaltung benötigt wird.The arrangement described below enables the control in a simple manner a magnetic switching, as z. B. required for automatic electrical dewatering will.

An einer bei 3 befestigten Ausgleichsfeder 2 hängt isoliert ein geschlossener Metallzylinder i, der schwerer, als die zu regulierende Flüssigkeit ist und mit dem unteren Ende unter die zu regulierende Flüssigkeitsoberfläche W taucht. Steigt oder fällt das Wasser, so wird der Zylinder (Stab r) durch den veränderten Auftrieb den Steuerkontakt 12 heben oder senken und dadurch entweder den Stromkreis 12, 10 oder 12, ir schließen, welch letztere das zugehörige Relais betätigen. Durch diese Anordnung wird erreicht, daß bei größeren zu haltenden Niveauunterschieden (z. B. von mehreren Metern) der Weg des Steuerkontaktes 12 durch richtige Wahl der Ausgleichsfeder 2 beliebig klein gemacht werden kann, was z. B. bei Wasserhaltungen in Bergwerken der Raumersparnis und Einfachheit halber isehr wertvoll ist.A closed metal cylinder i, which is heavier than the liquid to be regulated and which dips with the lower end under the liquid surface W to be regulated, hangs in isolation from a compensating spring 2 fastened at 3. If the water rises or falls, the cylinder (rod r) will raise or lower the control contact 12 due to the changed buoyancy and thereby either close the circuit 12, 10 or 12, ir, which latter actuates the associated relay. This arrangement ensures that with larger level differences to be maintained (z. B. of several meters) the path of the control contact 12 can be made as small as desired by the correct choice of the balancing spring 2, which z. B. in the case of dewatering in mines, the saving of space and simplicity is very valuable.

Patent-Anspruch:Patent claim: Vorrichtung zur Betätigung von Steuerkontakten für !magnetische Schalter (Relais) in Abhängigkeit von den Schwankungen einer Flüssigkeitssäule, dadurch gekennzeichnet, daß zur Erzielung eines beliebig großen Weges für den Hauptsteuerkontakt (12) letzterer isoliert an einem in die Flüssigkeit (W) eintauchenden Metallzylinder (1), der an einer Ausgleichsfeder (2) hängt, befestigt ist, wodurch das Steigen oder Fallen der Flüssigkeitsoberfläche (W) den Steuerkontakt (12) je nach Wahl und Einstellung der Ausgleichsfeder (2) mehr oder weniger hebt oder senkt.Device for maneuvering control contacts for! Magnetic switch (relay) in response to fluctuations of a liquid column, characterized in that, to achieve an arbitrarily large path for the main control contact (12) the latter isolated on a dips into the liquid (W) metal cylinder (1 ), which is attached to a compensating spring (2), whereby the rising or falling of the liquid surface (W) raises or lowers the control contact (12) more or less depending on the choice and setting of the compensating spring (2).
