Description
Die Neuerung betrifft einen optisch-akustischen Sicherungswächter, der sich dadurch auszeichnet, daß beim Ausschalten des Sicherungselementes, z.B. durch einen Kurzschluß, gleichzeitig ein optisches und akustisches Signal abgegeben wird.The innovation concerns an optical-acoustic fuse monitor, which is characterized by the fact that when the fuse element is switched off, e.g. by a short circuit, an optical and acoustic signal is emitted simultaneously.
Bisher bleiben ausgeschaltete Sicherungselemente im Sicherungskasten unbemerkt bzw. werden bemerkt, wenn der ausgefallene Stromkreis benutzt werden soll und durch die ausgeschaltete Sicherung nicht geschlossen ist. Sofern überwachungsbedürftige Geräte und Anlagen durch diesen Stromkreis betrieben werden, kann ein unbemerkter Sicherungsausfall erhebliche Schäden anrichten.Up to now, switched-off fuse elements in the fuse box have remained unnoticed or are noticed when the failed circuit is to be used and is not closed by the switched-off fuse. If devices and systems that require monitoring are operated by this circuit, an unnoticed fuse failure can cause considerable damage.
Aufgabe der Erfindung ist es, ein Gerät zu entwickeln, welches ein optisches und akustisches Signal abgibt, wenn ein Sicherungselement ausfällt.The object of the invention is to develop a device that emits an optical and acoustic signal when a safety element fails.
Nach der Neuerung besteht der optisch-akustische Sicherungswächter aus einem U-förmigen Bügel, worauf eine Energiequelle, ein Schalter mit außenliegendem Schließkontakt, ein optischer und ein akustischer Signalgeber angebracht sind. Die Energiequelle ist mit dem Schalter, dem akustischen und dem optischen Signalgeber in einem einfachen Stromkreis miteinander verbunden. Der Schalter schließt den Stromkreis, wenn er von dem ausgeschalteten Sicherungselementhebel niedergedrückt wird.According to the innovation, the optical-acoustic fuse monitor consists of a U-shaped bracket on which a power source, a switch with an external closing contact, an optical and an acoustic signaling device are attached. The power source is connected to the switch, the acoustic and the optical signaling device in a simple circuit. The switch closes the circuit when it is pressed down by the deactivated fuse element lever.
Die Zeichnung gibt einen optisch-akustischen Sicherungswächter wieder.The drawing shows an optical-acoustic safety monitor.
Der U-förmige Klemmbügel (1) ist mit seinen kurzen Schenkeln (8 und 9) oben und unten am Sicherungselement (10) aufgesteckt. Auf dem langen Teil des Bügels (6) ist oben auf der Außenseite eine Vorrichtung zur Aufnahme von Batterien (3) angebracht. Der Ein/Ausschalter (2) ist mittig auf dem langen Teil des Bügels (6) montiert und zwar in der Weise, daß der Schließkontakt (J) in den Zwischenraum zwischen Sicherungsschalter (13) und Bügelinnenseite (12) ragt.The U-shaped clamp (1) is attached to the fuse element (10) with its short legs (8 and 9) at the top and bottom. A device for holding batteries (3) is attached to the outside of the long part of the clamp (6). The on/off switch (2) is mounted centrally on the long part of the clamp (6) in such a way that the closing contact (J) extends into the space between the fuse switch (13) and the inside of the clamp (12).
Der optische Signalgeber (4) und der akustische Signalgeber (5) sind unterhalb des Ein/Ausschalters (2) auf der langen Außenseite des Bügels (6) angebracht.The optical signal generator (4) and the acoustic signal generator (5) are mounted below the on/off switch (2) on the long outside of the bracket (6).
Fällt das Sicherungselement (10) aus, bewegt s'ich der'Sicherungselementschalter (13) nach unten und drückt den Schließkontakt (7) des Ein/Ausschalters (2) ebenfalls nach unten und schließt somit den Stromkreis. Der optische Signalgeber (4) und der akustische Signalgeber (5) signalisieren dann den Ausfall des Sicherungselementes (10).If the fuse element (10) fails, the fuse element switch (13) moves downwards and also pushes the closing contact (7) of the on/off switch (2) downwards, thus closing the circuit. The optical signal generator (4) and the acoustic signal generator (5) then signal the failure of the fuse element (10).
