Description

Klemme für Elektrizitätszähler zum Anschluß an Wandler. Es ist allgemein üblich, die Spannungsklemmen zwischen die Stromklemmen zu legen. Da die Spannungsklemmen, soweit sie nicht geerdet sind, ein bedeutend höheres Potential führen als die Stromklemmen, erfordert die Sicherheit des Zählers und der Anlage Stege zwischen den Strom- und Spannungsklemmen, deren Zahl durch diese Anordnung außerordentlich groß wird und unter Umständen den Wert n-i hat, wenn, wie nicht selten, zwischen allen benachbarten Klemmen Stege zu legen sind. Durch diese grüße Anzahl vergrößern sich die Kosten und die Baulänge der Klemme in hohem Maße.Terminal for electricity meter for connection to converter. It's general It is common practice to place the voltage terminals between the current terminals. Since the voltage terminals, if they are not earthed, have a significantly higher potential than the current terminals, requires the security of the meter and the system bridges between the power and Voltage terminals, the number of which is extremely large due to this arrangement and possibly has the value n-i if, as is not uncommon, between all neighboring Clamps webs are to be laid. This number increases the costs and the overall length of the clamp to a large extent.

Ein Ausführungsbeispiel für eine solche Klemme zeigt Abb. i.An embodiment of such a clamp is shown in Fig. I.

Die Erfindung soll diesem übelstand abhelfen. Es werden die Klemmen gleichen Potentials oder geringeren Potentialunterschiedes zusammengefaßt und in einem nicht mit Stegen versehenen Teil der Klemme untergebracht. Die Spannungsklemmen, soweit sie nicht geerdet sind und damit ein höheres Potential gegenüber den übrigen Klemmen haben, werden entweder links oder rechts von den übrigen Klemmen angeordnet. Damit erreicht die Anzahl der Stege in der Klemme ein Minimum. Sie wird stets nur gleich der Anzahl der nicht geerdete. Spannungsklemmen sein. Wie groß die Ersparnis hierdurch wird, mag folgendes Beispiel zeigen: Bei einer Zahl von io Klemmen, wie z. B. bei Abb. i für einen Drehstrom-Vierleiterzähler mit drei messenden Systemen, sind nach obigen Ausführungen io - i = 9 Stege erforderlich, erfindungsgemäß aber nur, wie Abb.3 zeigt, drei Stege entsprechend den drei nicht geerdeten Spannungsklemmen. Das bedeutet eine Raum- und Koseemexsparnxs für sechs Stege.The invention is intended to remedy this drawback. There will be the clamps same potential or lower potential difference and summarized in housed a non-web part of the clamp. The voltage terminals, as long as they are not earthed and thus a higher potential compared to the rest Terminals are placed either to the left or to the right of the remaining terminals. This means that the number of webs in the terminal is kept to a minimum. She will only ever equal to the number of ungrounded ones. Be voltage terminals. How big the savings the following example may show: With a number of io terminals, such as z. B. in Fig. I for a three-phase four-wire meter with three measuring systems, io - i = 9 webs are required according to the above statements, but according to the invention only, as shown in Fig. 3, three bars corresponding to the three non-earthed voltage terminals. That means a space and cost saving for six piers.

Eine fast ebenso große Ersparnis zeigt die Anordnung nach Abb. z für einen Drehstrom-Dreileiterzähler mit zwei messenden Systemen.The arrangement according to Fig. Z for a three-phase three-wire meter with two measuring systems.
