Description
Magnetschalter für den Stromkreis des elektrischen Kohlenantriebs von Bogenlampen Bei Bogenlampen mit elektrischem Antrieb ist es notwendig, Einrichtungen vorzusehen, die den Antrieb selbsttätig abschalten, wenn der Lichtbogen abreißt, um zu verhindern, däß die Lampenkohlen von dem weiterlaufenden Nachschub gegeneinandergedrückt werden. Bisher hat man zu diesem Zweck in den Lampenstromkreis besondere von Hand zu betätigende Schalter oder Fliehkraftschalter oder überspannungsschalter gelegt. Auch elektromagnetisch betätigte Quecksilberschalter sind hierfür bereits vorgeschlagen worden.Magnetic switch for the electric coal drive circuit of arc lamps For arc lamps with an electric drive it is necessary to have facilities provide that the drive switches off automatically if the arc breaks, to prevent the lamp coals from being pressed against each other by the ongoing supply will. So far one has for this purpose in the lamp circuit special by hand to be operated switch or centrifugal switch or overvoltage switch placed. Electromagnetically operated mercury switches have also already been proposed for this purpose been.
Gemäß der Erfindung dient an Stelle eines besonderen Magneten ein 'vom Lampenstrom erregter Blasmagnet gleichzeitig als Magnet zur Betätigung des Magnetschalters. Diese Bauart ist gegenüber den bekannten wesentr lieh einfacher und billiger und beansprucht weniger Raum. Besonders zweckmäßig ist eine Bauart, bei welcher der Schalter von einem Schenkel des Blasmagneten getragen wird.According to the invention, a special magnet is used instead of a special magnet '' Blow magnet excited by the lamp current at the same time as a magnet for actuating the Magnetic switch. This type of construction is simpler than the well-known wesentr borrowed and cheaper and takes up less space. A type of construction is particularly useful in which the switch is carried by one leg of the blow magnet.
Abb. i ist eine Vorderansicht der Anordnung teilweise im Schnitt.Fig. I is a front view of the assembly, partly in section.
Abb. z zeigt das Schaltschema.Fig. Z shows the circuit diagram.
Die Bogenlampenkohlen i und 2 werden von dem Nachschubmotor 3 mittels eines bekannten, nicht gezeichneten Getriebes einarider genähert. In der Nähe des Lampenspiegels q. ist der Blasmagnet 5 angeordnet. Auf dem einen Sehenkel6 des Blasmagneten ist z. B. mittels einer Schraube 7 eine aus Isolierstoff bestehende Schaltergrundplatte 8 befestigt, welche die mit Polschuheng und io versehenen Kontaktfedern i i und 12 trägt. Die Kontaktfeder 12 ist mit einem Weicheisenanker i 3 ausgerüstet, der an ihr z. B. angenietet ist und dem Ende des Magnetschenkels 6 gegenüberliegt.The arc lamp coals i and 2 are of the supply motor 3 by means of a known, not shown transmission approximated einarider. In the vicinity of the Lamp mirror q. the blow magnet 5 is arranged. On one leg 6 of the blow magnet is z. B. by means of a screw 7 made of insulating material switch base plate 8 attached, which the contact springs provided with Polschuheg and io i i and 12 carries. The contact spring 12 is equipped with a soft iron armature i 3, the at her z. B. is riveted and the end of the magnetic leg 6 is opposite.
Die Zuführung des Lampenstromes erfolgt durch die Leitungen 14 und 15 über einen nicht gezeichneten Belastungswiderstand. Wenn der Lichtbogen gezündet ist, also Strom fließt, so wird der Blasmagnet, um den die Stromzuführung z. B: in einigen Windungen herumgeführt ist, in. bekannter Weise erregt. Der Schenkel 6 ist dann imstande; den Anker 13 festzuhalten, so da.ß die am Ende der Federn r i und 12 vorgesehenen Kontakte 16 und 17 in Berührung miteinander gehalten werden. Solange der Lichtbogen besteht, regelt ein. im Motorstromkreis liegendes Relais 18 den Nachschub.The lamp current is supplied through lines 14 and 14 15 via a load resistance, not shown. When the arc is struck is, so current flows, the blow magnet to which the power supply z. B: is led around in a few turns, excited in a known manner. The thigh 6 is then able; to hold the armature 13 so that the at the end of the springs r Contacts 16 and 17 provided i and 12 are kept in contact with each other. As long as the arc exists, it regulates. relay located in the motor circuit 18 supplies.
Die Schaltung läßt sich auch so ausbilden, daß der Schalter 16, 17 nicht für die Leistung des Antriebsmotors 3 bemessen zu sein braucht.The circuit can also be designed so that the switch 16, 17 does not need to be dimensioned for the power of the drive motor 3.
