Bezeichnung: Mehrpolige Leitungsschutzschalter bzw. Kleinselbstschalter fUr höheres Gleichspannungsschaltvermögen Designation: Multi-pole circuit breaker or small circuit breaker for higher DC voltage switching capacity

Früher wurden Leitungsschutzschalter nach VDE 0641 vorwiegend sowohl für 380 V Wechselspannung als auch für 250 V Gleichspannung hergestellt und verwendet. Im Zuge der Verkleinerung der Geräte nach DIN 43 234 bzw. DIN 43 880, Entwurf Januar 1975, werden Leitungsschutzschalter nur noch für 380 V Wechselspannung gebaut. Ihre Verwendung ist auf niedrigere Werte der Gleichspannung weit unter dem in VDE 0641 genormten Wert von 250 V Gleichspannung beschränkt, weil diese Geräte in Gleichstromkreisen mit diesen Betriebsspannungen, Stromwerte wenig oberhalb des Nennstromes nicht einwandfrei abschalten können. Bekannt ist, daß mit diesen Geräten das schnelle Löschen der Gleichstromlichtbögen jedoch gelingt, wenn eine ausreichend große Zahl von Unterbrechungsstellenin Reihe geschaltet wird.In the past, circuit breakers according to VDE 0641 were mainly used for 380 V AC voltage as well as 250 V DC voltage are produced and used. In the course of the downsizing of the devices according to DIN 43 234 or DIN 43 880, Draft January 1975, miniature circuit breakers are only available for 380 V AC built. Their use is on lower values of DC voltage far below the value of 250 V DC standardized in VDE 0641, because these devices in DC circuits with these operating voltages, current values can not switch off properly a little above the rated current. It is known that these devices can be used to quickly extinguish direct current arcs however, it succeeds if there is a sufficiently large number of interruption points Is connected in series.

Wenn diese Reihenschaltung bei Leitungsschutzschaltern naoh DIN 43 880, Entwurf Januar 76, bzw. Kleinselbstschaltern nach DIN 43 234 jedoch durch äußere Verdrahtung hergestellt wird, so ist das normgemäße Teilungsmaß für die Aneinanderreihung dieser oder ähnlicher Installations-Einbaugeräte nicht mehr einzuhalten.If this series connection is used for circuit breakers according to DIN 43 880, draft January 76, or small circuit breakers according to DIN 43 234 but by external If wiring is established, the standard pitch is for the stringing together this or similar built-in installation devices can no longer be observed.

Die Lösung geht davon aus, die Gebrauchstauglichkeit dieser Geräte zu erhalten, durch geeignete Innenverdrahtung in einem mehrpoligen Leitungsschutzschalter der nachbeschriebenen und in Fig. 1 und 2 näher erläuterten Art. Bei drei, nach bekannter Art (1), mechanisch miteinander gekoppelten Leitungsschutzschaltern (2a, 2b, 2c) werden 2 Schalter (z.B. 2b und 2c) durch einen Leiter ausreichenden Stromführungsvermögens derart in Reihe geschaltet, daß .die Abgangsklemme (4c) des einen mit der Zuleitungsklemme (4b) des anderen Schalters verbunden ist.The solution assumes that these devices are still usable, by suitable internal wiring in a multi-pole miniature circuit breaker of the type described below and explained in more detail in FIGS. 1 and 2. With three circuit breakers mechanically coupled to one another in the known manner (1) (2a, 2b, 2c) 2 switches (e.g. 2b and 2c) are connected in series by a conductor with sufficient current carrying capacity in such a way that .the Output terminal (4c) of the one with the supply terminal (4b) of the other switch connected is.

Der Leiter (3) ist zwischen den verbundenen Schaltern hindurchgeführt und aus so hinreichend flachem Material, daß das normmäßige Breitenmaß als Vielfaches des Teilungsmaßes 18 mm nicht überschritten wird. Die Anschlußpunkte (5) des verbindenden Leiters sind mit geeigneten und an sich bekannten Verbindungsverfahren wie z.B. Löten, Schweißen, Nieten, Verschrauben mittels Schrauben mit Abscherkopf, derart gesichert, daß das Anschließen eines von außen herangeführten Leiters mit üblichen Mitteln nicht möglich ist.The conductor (3) is passed between the connected switches and made of sufficiently flat material that the normal width dimension as a multiple of the division dimension 18 mm is not exceeded. The connection points (5) of the connecting conductor are using suitable and known connection methods such as soldering, welding, riveting, screwing by means of screws with a shear head, secured in such a way that one can be connected from the outside Ladder is not possible with the usual means.
