Beschreibungdescription

Die Heuerung bezieht sich auf ein Gerät, mit dem die Funktion von M-Sicherungen in einfacher Weise überwacht werden kann.The hiring refers to a device with which the Function of M-fuses monitored in a simple way can be.

Es gibt zwar schon Überwachungsgeräte, die das Defektwerden einer NH-Sicherung melden und dadurch in Bingnetzen längere Betriebsunterbrechungen von Anlagen und Maschinen unnötig machen. Diese Geräte bestehen aus elektrischen ode elektronischen Schaltungen, die unter Ausnutzung der Spannungsdifferenz vor und hinter einer defekten Sicherung in Eingnetzen den "Fehler melden. Die Art dieser Überwachung hat aber den Nachteil, daß die Anschaffung und der Einbau der Geräte hohe Kosten verursachen, ein Trennen von Ringnetzen möglich ist ohne die Sicherungsüberwachung zu trennen und dadurch Gefahrenmomente entstehen»There are already monitoring devices that report a defect in an NH fuse and thus longer in Bing networks Make operational interruptions of systems and machines unnecessary. These devices consist of electrical or electronic Circuits that utilize the voltage difference in front of and behind a defective fuse in a network Report the error. The type of this monitoring has the disadvantage that the acquisition and installation of the Devices cause high costs, a separation of ring networks is possible without disconnecting the fuse monitoring and this creates dangerous moments »

Die Neuerung dient dem Zweck, diese Mängel zu beheben und wird dargestellt durchThe purpose of the innovation is to remedy these deficiencies and is represented by

Abb. 3 in Seitenansicht auf eine HH-Sicherung aufgesteckt. Sie besteht aus einem Gerät aus Kunststoff 1, das anstelle des Sicherungsgriffes auf die NH-Sicherung 2 aufgesteckt wird. An dem Gerät ist ein Kontakt 3 so angebracht, daß durch den herausspringenden Kennmelder 4, beim Defektwerden der EH-Sicherung, der Kontakt Spannung erhält. Mit dem Kontakt ist, über einen Signaldraht 5 und eine Feinsicherung 6, ein Fehlermelder elektrisch verbunden. Die Feinsicherung wirkt als Kurzschlußschutz bei Anschluß mehrerer Geräte an einen Fehlermelder. Seitlich am Gerät sind Griffleisten 7 ausgebildet, um ein Abnehmen des Gerätes unter Spannung zu ermöglichen. Eine Feder 8 bewirkt festen Sitz des Gerätes auf der HH-Sicherung. Beim Ziehen der HB-Sicherung muß das Gerät zwangsläufig vorher abgenommen werden; dadurch wird eine einwandfreie Trennung des Bingnetzes gewährleistet.Fig. 3 in side view attached to a HV HRC fuse. It consists of a device made of plastic 1 that instead of of the fuse handle attached to the NH fuse 2 will. A contact 3 is attached to the device in such a way that when the indicator 4 pops out, it becomes defective the EH fuse, the contact receives voltage. With the contact is, via a signal wire 5 and a microfuse 6, a fault indicator is electrically connected. The microfuse acts as short-circuit protection when several devices are connected an error message. There are handle strips 7 on the side of the device designed to enable removal of the device under tension. A spring 8 ensures a tight fit of the device on the HH fuse. When pulling the HB fuse, it must Device must necessarily be removed beforehand; this ensures a perfect separation of the Bingnetz.
