Abstract

In the case of a four-pole main switch (FI switch) in domestic distribution systems on a three-phase mains power supply linked in the form of a star, in order to avoid the possibility of accidental energising as a result of an interruption in the neutral conductor or as a result of defective installation, at least another one of the three phase conductor contacts is provided with a lead with respect to the others, in addition to the neutral conductor contact of the main switch.

Description

Die Erfindung bezieht sich auf den bei einem Drehstromnetz mit sternförmiger Verkettung auf Seiten der Hausverteilung angeordneten Hauptschalter in 4-poliger Ausführung.The invention relates to that in a three-phase network with star-shaped chaining on the part of the house distribution arranged main switch in 4-pole version.

Um dabei eine anlagenseitige Spannungsverschleppung über die zwischen dem Neutralleiter und den vorhandenen Phasenleitern angeschlossenen Verbraucher und deren Zerstörung durch die verkettete Spannung zu verhindern, sind derartige Haupt­ schalter dahingehend ausgebildet, daß ihr Unterbrechungs­ kontakt für den Neutralleiter beim Einschalten vor den drei Phasenleiterkontakten schließt und beim Ausschalten nach diesen öffnet (DE 30 29 094 A1).In order to carry out a voltage carryover via the between the neutral conductor and the existing phase conductors connected consumers and their destruction by the Preventing chained tension are such major switch trained that your interruption contact for the neutral conductor when switching on before the three Phase conductor contacts closes and when switched off this opens (DE 30 29 094 A1).

Diese Vorkehrung ist jedoch an eine einheitliche Positionie­ rung der Hauptschalterkontakte und ihrer Leitungsanschlüsse auf Seiten der Einbaugeräte gebunden. Da diesbezüglich die Installationsgewohnheiten in den europäischen Ländern diffe­ rieren, läßt sich im Hinblick auf einen gemeinsamen Binnen­ markt das Nebeneinander verschiedener Ausführungen und die Gefahr routinebedingter Fehlanschlüsse nicht vermeiden. Zwar hat man bereits versucht, dieser Gerätevielfalt mit Konstruk­ tionen zu begegnen, deren Schaltvorgang auf wenige Milli­ sekunden begrenzt ist und damit die Gefährdungsmöglichkeit verringert. Derartige Ausführungen sind jedoch relativ auf­ wendig wie teuer und neigen aufgrund der Momentschaltung zum Einschaltprellen der Kontakte und daraufhin zum Verschweißen.However, this precaution is in a uniform position the main switch contacts and their line connections bound on the part of the built-in devices. Since in this regard Installation habits in European countries diffe can be categorized with a view to a common interior markets the juxtaposition of different designs and the Do not avoid the risk of routine incorrect connections. Though one has already tried this variety of devices with construct counteracting whose switching process to a few milli seconds and is therefore a hazard decreased. However, such designs are relative to manoeuvrable as well as expensive and tend due to the torque switching Bouncing of the contacts and then for welding.

In Anbetracht dessen liegt der Erfindung die Aufgabe zugrunde, den 4-poligen Hauptschalter von derart unerläßlichen Anschluß­ bedingungen zu befreien und einheitlich "installationssicher" zu machen. In view of this, the object of the invention is the 4-pin main switch of such an essential connection free conditions and uniform "installation safe" close.  

Zur Lösung dieser Aufgabe bildet die Erfindung einen Haupt­ schalter für Vierleiter-Drehstromnetze nach dem Oberbegriff des Patentanspruchs 1 gemäß den in dessen Kennzeichenteil an­ gegebenen Merkmalen aus. Dabei beruht die Erfindung auf der Erkenntnis, daß ein Ausfall des Neutralleiters vor der Haus­ verteilung z. B. aufgrund einer Unterbrechung oder ein unbe­ absichtigtes Vertauschen der vorgesehenen Anschlüsse von Phasen- und Neutralleitern im Zuge der Einbaumontage und Installation eine Zerstörung der für die Nennspannung von 220 V ausgelegten und angeschlossenen Verbraucher durch die verkettete Spannung von 380 V zur Folge haben kann. Diese Fehlermöglichkeit wird gemäß der Erfindung dadurch ausge­ schlossen, daß nicht nur der Schaltkontakt für den Neutral­ leiter, sondern auch noch mindestens ein weiterer Schalt­ kontakt für einen der Phasenleiter mit Vorlauf ausgestattet wird, um auf diese Weise die Möglichkeit einer Spannungs­ verschleppung beim Ein- und Ausschalten durch die fehlende oder verspätet zustandegekommene Neutralleiterverbindung zu verringern bzw. gänzlich auszuschließen.The invention forms a major part of solving this problem switches for four-wire three-phase networks according to the generic term of claim 1 according to the in its characterizing part given characteristics. The invention is based on the Realization that a failure of the neutral wire in front of the house distribution z. B. due to an interruption or an unbe deliberate swapping of the intended connections of Phase and neutral conductors during installation and Installation a destruction for the nominal voltage of 220 V designed and connected consumers by the chain voltage of 380 V can result. This According to the invention, the possibility of error is thereby eliminated concluded that not only the switch contact for the neutral head, but also at least one other switch contact for one of the phase conductors with lead will, in this way, the possibility of a tension procrastination when switching on and off due to the lack or delayed neutral connection to reduce or exclude entirely.

Im Hinblick auf die national unterschiedliche Installations­ praktik und die dabei uneinheitlich differierende Anordnung der Anschlußklemme für den Neutralleiter rechts oder links neben den insgesamt in Reihe gelegenen drei Phasenanschluß­ klemmen ist gemäß dem Merkmal des Anspruchs 2 vorgesehen, für den Normalfall nur die mit den beiden äußeren Klemmen der Anschlußleiste verbundenen Schaltkontakte den anderen beiden gegenüber mit Vorlauf auszustatten, um so mit Sicherheit den Neutralleiter mitzuerfassen.With regard to the nationally different installation practice and the inconsistently different arrangement the terminal for the neutral conductor on the right or left in addition to the three phase connections in total clamp is provided according to the feature of claim 2 for normally only those with the two outer terminals of the Terminal block connected switching contacts the other two opposite with advance notice, so that with certainty Neutral conductor included.

Dabei läßt sich die Schaltfolge der Kontakte bzw. deren Folge­ betätigung auf bekannte Weise durch die Art der Bewegung, die gegenständliche Ausbildung der Schaltglieder und durch deren Betätigungsmechanismen bestimmen, ohne daß es dazu im einzel­ nen besonderer Hinweise oder einer zeichnerischen Darstellung bedarf. The switching sequence of the contacts or their sequence can be made actuation in a known manner by the type of movement that objective training of the switching elements and by their Determine actuation mechanisms without this being detailed NEN special notes or a graphic representation requirement.  

Nach dem Merkmal des Anspruchs 3 kann die erfindungsgemäße Kontaktfolgebetätigung im Zuge des Ein- und Ausschaltvorgangs auch auf einen als Hauptschalter in die Hausverteilung ein­ gesetzten Fehlerstromschutzschalter angewendet werden, ohne daß sich an dessen elektrischer Funktion etwas zu ändern braucht.According to the feature of claim 3, the invention Follow-up operation in the course of the switching on and off also as a main switch in the house distribution set residual current circuit breaker can be applied without that something changes in its electrical function needs.
