Description
Titel: Einzellichtschalter für automatisch gesteuerteTitle: Single light switch for automatically controlled
Beleuchtungsanlagen Zusatz zum Patent ... (Patentanmeldung P 30 18 946.9) und zum Zusatzpatent .... Lighting systems addendum to the patent ... (patent application P 30 18 946.9) and the additional patent ....
(Zusatzpatentanmeldung P 30 29 200.3) In der Patentanmeldung P 30 18 947.9 ist ein tinzellicht schalter mit Zweidrahtanschluß für automatisch durch Impulsschalter gesteuerte Beleuchtungsanlagen beschrieben, der durch ein durch kurzzeitigen Stromstoß bedienbares Schaltelement (1) mit einem einzigen Schaltkontakt im Hauptstromkreis und zwei unabhängig voneinander bedienbare Schaltelemente (2) und (3) mit einer Dauerschaltstellung und einer kurzzeitig einstellbaren, veränderlichen Schaltstellung gekennzeichnet ist, wobei das eine Schaltelement (2) im Hauptstromkreis angeordnet ist und in seiner Dauerschaltstellung den Hauptstromkreis schlief.t, während das andere Schaltelement (3) zum Schaltelement (1) so parallel geschaltet ist, daß es in seiner kurzzeitig einstellbaren, veränderlichen Schaltstellung den Hauptstromkreis kurzzeitig auch schließt, wenn der Hauptstromkreis durch das Schaltelement (1) geöffnet ist. In einer bevorzugten Ausführungsform ist das Schaltelement (1) in Form eines durch eine Magnetspule zu betätigenden Schaltkontaktes ausgebildet, wobei die Magnetspule im Hauptstromkreis geschaltet ist, so daß der Schaltkontakt geschlossen wird, wenn Strom durch den Hauptstromkreis fließt, geschlossen gehalten wird, solange Strom durch den Hauptstromkreis fließt, und sich öffnet, wenn der Stror im Hauptstromkreis unterbrochen wird. Diese durch Magnetspule gesteuerten Schaltelemente ermöglichen zwar eine zugeordnete Schaltkontakt geschlossen. Sobald die Stärke des durch die Spule (4a) fließenden Stromes auf mindestens das 3-, vorzugsweise 4-fache derjenigen Stromstärke ansteigt, bei der der Magnetschalter mit der Magnetspule (4a) den zugeordneten Kontakt gerade schließt und geschlossen hält, wird die Anziehungskraft sei es des anderen Teils des U-förmigen gemeinsamen Magnetkernes, sei es des Magnetkernes mit den beiden Wicklungen derart stark erregt, daß auch der der Magnetspule (4b) zugeordnete Kontakt schließt und geschlossen gehalten werden kann. (Additional patent application P 30 29 200.3) In the patent application P 30 18 947.9 is a single light switch with two-wire connection for automatic through Impulse switch controlled lighting systems described by a short-term Impulse operated switching element (1) with a single switching contact in the main circuit and two independently operable switching elements (2) and (3) with one Permanent switch position and a short-term adjustable, changeable switch position is characterized, wherein the one switching element (2) is arranged in the main circuit and closes the main circuit in its permanent switch position, while the other switching element (3) is connected in parallel to the switching element (1) so that it the main circuit in its briefly adjustable, changeable switch position also closes briefly when the main circuit is opened by the switching element (1) is. In a preferred embodiment, the switching element (1) is in the form of a formed by a solenoid to be actuated switching contact, the solenoid is switched in the main circuit, so that the switching contact is closed when Current flowing through the main circuit is kept closed as long as current flows through the main circuit, and opens when the current in the main circuit is interrupted. This solenoid-controlled switching elements enable although one assigned switching contact closed. Once the strength of the current flowing through the coil (4a) to at least 3, preferably 4 times the current strength at which the magnetic switch with the magnetic coil increases (4a) the associated contact just closes and keeps closed, the attraction force be it the other part of the U-shaped common magnetic core, be it the magnetic core with the two windings so strongly excited that the magnet coil (4b) assigned contact closes and can be kept closed.
Da diese Spule auf eine größere Magnetleistung ausgelegt ist, entlastet die Spule (4b) die Spule (4a) bei Lastschwankungen in den oberen Bereich, so daß eine übermäßige Erhitzung des Gesamtmagnetschalters vermieden wird.Since this coil is designed for a larger magnet power, it is relieved the coil (4b) the coil (4a) in the case of load fluctuations in the upper range, so that excessive heating of the entire magnetic switch is avoided.
Soll der Einzelschalter ausgeschaltet werden, wird durch Betätigung des Schalters (2,5) dessen Schaltkontakt (5) kurzzeitig geöffnet und werden, bedingt durch die Stromunterbrechung, auch die beiden Kontakte des Gesamtmagnetschalters geöffnet.If the individual switch is to be switched off, press it of the switch (2,5) whose switch contact (5) is opened briefly and are conditional due to the power interruption, also the two contacts of the overall magnetic switch opened.
Bei der erfindungsgemäßen Neuerung wird somit der Schwankungsbereich der Magnetleistung unterteilt, so daß die Magnetspule aus Belastbarkeitsgründen nicht entsprechend der größten Magnetleistung im Schwankungsbereich ausgelegt werden muß, um nicht übermäßig viel Wärme zu erzeugen. Die genaue Aufteilung des Gesamtleistungsbereichs geschieht zweckmäßig derart, daß die für kleine Magnetleistung ausgelegte Magnetspule etwa ein Drittel des Gesamtschwankungsbereichs abdeckt und etwa zwei Drittel des Bereichs von der für größere Magnetleistung ausgelegten Magnetspule bedient wird. Die genaue Aufteilung ist dabei empirisch für die jeweilige Ausgestaltung von Doppelmagnet und Schaltkontakten zu ermitteln.In the case of the innovation according to the invention, the range of fluctuation thus becomes divided by the magnetic power, so that the magnetic coil for reasons of resilience cannot be designed according to the greatest magnet power in the fluctuation range must in order not to generate excessive heat. The exact division of the total service area expediently takes place in such a way that the magnet coil designed for small magnet power covers about one third of the total fluctuation range and about two thirds of the Area is operated by the solenoid designed for greater solenoid power. The exact division is empirical for the respective design of double magnet and switching contacts.
