InstallationsselbstschalterInstallation auto switch

Es sind Selbstschalter bekannt, bei denen die Kontakte so ausgebildet sind, daß sie durch die elektrodynamischen Kräfte des Furzschlußstromes geöffnet werden. Es ist auch bekannt, diese Kräfte mit Eisenkernen zu verstärken.There are known circuit breakers in which the contacts are designed in this way are that they are opened by the electrodynamic forces of the short circuit current. It is also known this To reinforce forces with iron cores.

Eine wesentliche Verbesserung gegenüber dem Bekannten stellt die Steuerung dar. - ·The controls represent a significant improvement over the familiar. - ·

Sie betrifft einen Installationsselbstschalter mit einer elektrodynamischen Schnellauslösung, bei der von den beiden in entgegengesetzter Richtung stromdurchflossenen Kontakteilen der feste Kontaktteil eisenumschlossen ist, und bei dem durch den Luftspalt eines den festen Kontaktteil umschließenden Eisenkernes der bewegliche Kontaktteil ragt,- -It concerns an installation circuit breaker with an electrodynamic one Rapid tripping in the case of the two contact parts of the fixed contact part is iron-enclosed, and in which by the air gap of an iron core surrounding the fixed contact part the moving contact part protrudes, - -

Besonders vorteilhaft ist, den beweglichen Kontaktteil schienenartig mit einem rechteckigen Querschnitt zu versehen und so in dem Luftspalt des den festen Kontaktteil umschließenden Eisens anzuordnen, daß der Magnetfluß den Kontaktteil senkrecht zu der Längsseite seines rechteckigen Querschnittes durchflutet. Dadurch kann der Luftspalt sehr schmal ausgebildet und der magnetische Widerstand entsprechend klein sein.It is particularly advantageous for the movable contact part to be in the form of a rail to be provided with a rectangular cross-section and so in the air gap of the iron surrounding the fixed contact part to arrange that the magnetic flux flows through the contact part perpendicular to the longitudinal side of its rectangular cross-section. Through this the air gap can be made very narrow and the magnetic resistance can be correspondingly small.

In den Mg. 1 und 2 ist ein Beispiel der !Feuerung dargestellt. Dabei ist Fig. 2 ein Sehnittbild der Pig* I.An example of the furnace is shown in Figs. 1 and 2. Fig. 2 is a sectional view of the Pig * I.

Zu einem feststehenden-Kontaktarm 1 ist außerhalb der Kontaktstelle Io in geringem Abstand ein beweglicher Fontaktarm 2A stationary contact arm 1 is outside the contact point Io, a short distance away, is a movable arm of the font 2

angeordnet und auf einem Stift 3 gelagert. Der feststehende Zontaktarm 1 wird von einem Eisenkern 4, der vorzugsweise lamelliert ist, umschlossen. In einem Schlitz 5 des Eisenkerns 4 ist der bewegliche Kontaktarm 2 angeordnet, der im Bereich des Eisenkernes eine Isolation 6 aufweist. Die Kontaktstelle Io sowie die Lichtbogenhörner 7 und 8 der Kontaktarme 1 und 2 sind in einer Lichtbogenkammer 9 untergebracht. Mit J ist der Strom bezeichnet.arranged and stored on a pin 3. The fixed Zontaktarm 1 is of an iron core 4, which is preferably is laminated, enclosed. In a slot 5 of the iron core 4, the movable contact arm 2 is arranged, which in the Has an insulation 6 in the area of the iron core. The contact point Io and the arcing horns 7 and 8 of the contact arms 1 and 2 are housed in an arc chamber 9. The current is denoted by J.

Bei dieser .Ausbildung der eisenumschlossenen Kontaktarme 1,2 treten bei Kurzschlußströmen, die in der Größenordnung von looo A liegen, bereits Kräfte von einigen'Hundert Gramm auf, die in diesem Falle eine schnelle Öffnung der Kontakte bewirken. Zur weiteren elektrodynamischen Kraftwirkung kann man in an sich bekannter Weise den festen Kontaktteil mehrmals um den Eisenkern wickeln.In this. Training of the iron-enclosed contact arms 1,2 For short-circuit currents of the order of magnitude of looo A, forces of a few hundred grams already occur, which in this case cause the contacts to open quickly. For further electrodynamic force effects one can in itself As is known, wrap the fixed contact part several times around the iron core.

Außer der schnellen Abschaltung bei Kurzschlüssen bietet der installationsselbstschalter entsprechend der Feuerung den Vorteil einer wesentlich größeren Selektivität gegenüber den vorgeschalteten Schmelzsicherungen. Darüberhinaus wird die thermische und mechanische Beanspruchung der Schaltstrecke erheblich herabgesetzt, wodurch das Schaltvermögen des Selbstschalters vergrößert wird oder seine Baugröße bei gleichem Schaltvermögen entsprechend verkleinert werden kann.In addition to the quick shutdown in the event of a short circuit, the automatic installation switch offers the advantage of the type of furnace a much greater selectivity compared to the upstream fuses. In addition, the thermal and mechanical stress on the switching path is significantly reduced, thereby reducing the switching capacity of the circuit breaker is enlarged or its size can be reduced accordingly with the same switching capacity.
