ElektrischeElectric Hoehleistun^s-Sicherungen für erhöhte Sicherheit im BetriebeοHigh performance fuses for increased safety in the company o

Die Auswechslung von Hochleistungs-Sicherungen mit Messerkontakten in. elektrischen Anlagen wirä im allgemeinen durch Aufsetzen eines isolieren den Ha ndgriffes ausgeführt. Dafür sind genormte Schwalbenschwanz—föymi^ ge Stege an den Stirnseiten der Sicherungen -vorgesehen. Nachteilig sind dabei diese über den keramischen Sicherungskörper herausragenden & unter Spannung liegenden metallischen Profile.
TJm die Gefa hren der Serührung bei unvorsichtiger Handhabung auszusehlJBS sen hat man schon in Sonder-Ausführungen die metallischen Stirnplatten mit Steg durch isolierende Kunststoffplatten gleicher Form ersetzt. Die geringe Wärmebeständigkeit der dafür verfügbaren Kunststoffe bedingt besondere, schü tzende Asbestunterlagen«, Es sind aber auch dann noch Unsicherheiten vorhanden in der Beherrschung der bei einer Kurzschluss-Abschaltung innerhalb der Sicherung frei werdenden Energie, welche von den metallischen Stirnplatten zuverlässig abgeschirmt werden kann, Na ch dem Sinne der neuartigen Ausführung wird unter Beibehaltung der zuverlässigeren metallischen Stirnplatten das gesamte über den eingesetzten Sicherungskörper vorderseitig herausragende Metall-Profil (mit Steg) mit einem geeigneten isolierenden Material umkleidet. Das kann durch Umpressen, mit einem foijfce ständigen Kunststoff geschehen· Erreicht wird damit eine wesentliche Verbesserung der Betriebsicherheit für das bedienende Personal unter gleichzeitiger Beibehaltung höchster mechanischer & elektrischer Werte»
Der Tollständigkeit halber sei noch erwähnt» dass der isolierende Schlitz auch durch Aufschrumpfen von PTC-hart - & entsprechend zu verarbeitender Isolierstoffe ausgeführt werden 'kann* The replacement of high-performance fuses with blade contacts in electrical systems is generally carried out by putting on an isolating handle. For this purpose, standardized dovetail shaped webs on the front sides of the fuses are provided. These metallic profiles protruding above the ceramic fuse body and which are under tension are disadvantageous.
In order to avoid the danger of contact in the event of careless handling, the metallic face plates with webs have already been replaced in special designs by insulating plastic plates of the same shape. The low heat resistance of the plastics available for this requires special, protective asbestos underlays. " According to the new design, while retaining the more reliable metallic face plates, the entire metal profile (with a web) protruding from the front of the fuse body used is clad with a suitable insulating material. This can be done by overmolding, with a foijfce permanent plastic · This achieves a significant improvement in operational safety for the operating personnel while at the same time maintaining the highest mechanical and electrical values »
For the sake of completeness, it should also be mentioned »that the insulating slot can also be made by shrinking on PTC-hard & appropriately processed insulating materials ' *
