Schalter für gekühlte elektrische Apparate. Patentiert im Deutschen Reiche vom 14. November 1905 ab. Switches for refrigerated electrical apparatus. Patented in the German Empire on November 14, 1905.
Bei elektrischen Apparaten, welche während des Betriebes gekühlt werden müssen, ist es erwünscht, die Inbetriebsetzung dieser Apparate zu verhindern, solange nicht das Kühlmittel in Wirksamkeit tritt.For electrical devices that have to be cooled during operation, it is desirable to prevent these apparatuses from operating unless that Coolant comes into effect.
Man hat nun schon z. B. mit dem Absperrventil in der Wasserleitung einen Schalter verbunden, der nur bei öffnung des Ventiles Strom in den zu kühlenden ApparatOne has now z. B. a switch with the shut-off valve in the water pipe connected, which only flows into the apparatus to be cooled when the valve is opened
ίο schickt. Abgesehen davon, daß diese Einrichtung eine abnormale Ausführung des Wasserhahnes oder Ventiles verlangt, -verhindert sie nicht den Stromschluß bezw. die Inbetriebsetzung des elektrischen Apparates, wenn aus irgendwelchem Grunde beim Öffnen des Hahnes usw. die Wasserleitung kein Wasser gibt.ίο sends. Besides that this facility an abnormal design of the faucet or valve requires, -prevents the current connection respectively. the Start-up of the electrical apparatus if, for whatever reason, the water pipe is opened when the tap etc. there is no water.
Gegenstand vorliegender Erfindung ist nun eine Einrichtung, welche die Inbetriebsetzung von zu kühlenden elektrischen Apparaten davon abhängig macht, daß die zur Kühlung unmittelbar oder zur Bewegung des Kühlmittels dienende Flüssigkeit (oder Luft usw.) tatsächlich strömt.The present invention is now a device, which the commissioning of electrical equipment to be cooled makes it dependent on that for cooling Liquid (or air, etc.) used directly or to move the coolant actually flows.
Ein Ausführungsbeispiel der Erfindung ist in beiliegender Zeichnung im Schnitte dargestellt. Hierbei ist angenommen, daß durch einen mit Wasser betriebenen Ejektor α durch die Öffnung b zur Kühlung verwendete Luft durch den elektrischen Apparat, beispielsweise einen Ozonisator, hindurchgesaugt wird. Vor der Düse des Ejektors — im Sinne der Wasserströmung gesehen — ist ein Stutzen c vorgesehen, dessen Öffnung durch eine Membrane d verschlossen ist. Sobald nun durch den Hahn e Wasser in den Ejektor eintritt, wird durch den infolge der Querschnittsverengung der Düse hervorgerufenen Wasserdruck die Membrane derart bewegt, daß die beiden Stromschlußstücke f und g miteinander in Berührung gebracht werden.An embodiment of the invention is shown in section in the accompanying drawing. It is assumed here that air used for cooling is sucked through the electrical apparatus, for example an ozonizer, by a water-operated ejector α through the opening b. In front of the nozzle of the ejector - viewed in terms of the water flow - a connector c is provided, the opening of which is closed by a membrane d. As soon as water enters the ejector through the faucet e, the water pressure caused by the cross-sectional constriction of the nozzle moves the membrane in such a way that the two current connection pieces f and g are brought into contact with one another.
Bei diesem Ausführungsbeispiele wird zweckmäßig die in dem Ozonisator etwa keimfrei zu machende Flüssigkeit selbst durch den . Ejektor α geleitet und zur Herbeiführung des Stromschlusses benutzt.In this exemplary embodiment, the liquid to be made approximately sterile in the ozonizer is expediently itself through the. Ejector α directed and used to bring about the electrical connection.
An Stelle der -Membrane d kann natürlich jedes andere zur Druckmessung verwendbare Glied, z. B. eine Bourdonsche Feder, ein Quecksilbermanometer usw. treten. Ebenso kann die Stromschlußvorrichtung anstatt an einer Stelle, an welcher während des Durch- ■ fließens der Flüssigkeit eine. Druckerhöhung eintritt, wie gezeichnet ist, auch an einer Stelle, z. B. in der Nähe des Saugstutzens b, angebracht werden, an welcher Druckminderung auftritt. Hierbei ist nur die Anordnung der Stromschlußstücke so zu treffen, daß sie bei einer Bewegung der Membrane, Bourdonfeder usw. in der anderen Richtung geschlossen wird. Je nach, den besonderen Umständen kann hierbei die Schaltbewegung von hydrodynamischen oder hydrostatischen Druckänderungen abhängig gemacht werden; an Stelle des Manometers können auch in den Weg der Strömung gestellte Schaufeln, z. B, eines Turbinenrades, gebracht werden.Instead of the membrane d , any other member that can be used for pressure measurement, e.g. B. a Bourdon spring, a mercury manometer, etc. occur. Likewise, instead of at a point at which the liquid flows through, the current connection device can. Pressure increase occurs, as shown, also at one point, e.g. B. in the vicinity of the suction port b, be attached at which pressure reduction occurs. The only thing that needs to be done is to arrange the current connection pieces in such a way that they are closed when the diaphragm, Bourdon tube, etc. move in the other direction. Depending on the particular circumstances, the switching movement can be made dependent on hydrodynamic or hydrostatic pressure changes; Instead of the pressure gauge, blades placed in the path of the flow, e.g. B, a turbine wheel.

Endlich kann auch die Einrichtung gemäß der Erfindung so getroffen werden, daß von dem Druckmesser ein von Hand zu bewegender Schalter so lange gesperrt wird, bis die Kühlung in Tätigkeit gesetzt ist.Finally, the device according to the invention can be made so that of the pressure gauge, a switch to be moved by hand is locked until the Cooling is in operation.
