Abstract

the current transducer has a shape-locking primary rail clamp with a lug which forms a single unit with the transducer. The lug is movable forwards and backwards and prevented from falling out by its associated bolt

Description

Kritik am Stand der TechnikCriticism of the state of the art

Der ersten Generation von Schienenstromwand­ lern wurden zusätzlich metallene Laschen (Primärschienenklemme), mit je einem Schraub­ bolzen an Anfang und Ende, beigestellt, um diesen auf der stromführenden Primärschiene arretieren zu können (Bild 1).The first generation of rail current transformers were also provided with metal tabs (primary rail clamp), each with a screw bolt at the beginning and end, so that they could be locked onto the current-carrying primary rail ( Fig. 1).

Diese Lösung (unpraktische Montage, Verlust der Lasche bei der Montage, wurde in der darauffolgenden Generation durch am Kunst­ stoffgehäuse fest angebrachte "Nasen", ver­ bessert, die entweder eine Mutter mit Schraubbolzen aufnehmen können, oder bereits selbst ein Gewinde für den Bolzen enthalten (Bild 2).This solution (impractical assembly, loss of the bracket during assembly, was improved in the next generation by "noses" attached to the plastic housing, which can either accommodate a nut with a bolt or already contain a thread for the bolt ( Image 2).

Da heute zunehmend Stromwandler hinter Si­ cherungs- oder Trennleisten montiert werden sollen, ist das bei Wandler mit den be­ schriebenen "Nasen" nicht möglich, so daß für diesen Fall auf die ältere Generation zurückgegriffen werden muß.As current transformers behind Si fuse or isolating strips can be installed should be with converter with the be written "noses" not possible, so that in this case to the older generation must be used.

PatentbeschreibungPatent description

Die Erfindung, für die Schutz begehrt wird, betrifft, zur Vermeidung der beschriebenen Nachteile, eine Ausführung der oben be­ schriebenen ersten Generation, jedoch ist die Verbindung zwischen Wandler und Lasche formschlüssig derart, daß die Lasche mit dem Wandler eine unverlierbare Einheit bildet (Bild 3). Die Lasche ist nach vorn und hin­ ten verschiebbar, wird jedoch durch die ein­ geschraubten Bolzen am Herausfallen gehin­ dert. Gebietet die Montage einen Wandler ohne Laschen (wie zum Beispiel bei der oben erwähnten Montage hinter Sicherungs- und Lasttrennern), so kann durch Herausschrauben eines Bolzens die Lasche herausgezogen wer­ den.The invention, for which protection is sought, concerns, in order to avoid the disadvantages described, an embodiment of the first generation described above, but the connection between the converter and the plate is form-fitting in such a way that the plate forms a captive unit with the converter ( Figure 3 ). The tab can be moved forward and backward, but is prevented by the screwed-in bolt from falling out. If the assembly affects a converter without tabs (as for example in the assembly mentioned above behind fuse and load disconnectors), the tab can be pulled out by unscrewing a bolt.
