Description

Überwachungseinrichtung mittels im Magnetfeld beeinflußbarer Kontakte.Monitoring device by means of contacts that can be influenced in the magnetic field.

Unter dem Namen"Reed-Kontakte"sind in eine Glasröhre mit Schutzgas eingeschlossene Kontakte bekanntgeworden, deren Betätigung im Feld eienr Magnetspule erfolgt. Infolge des Einschlusses dieser Kontakte in eine Glasröhre werden sie in ihrer Funktion nicht durch Staub oder aggressive Gase gestört, so daß sie ohne Wartung auch nach langen Betriebspausen zuverlässig arbeiten.Under the name "Reed contacts" are in a glass tube with protective gas Enclosed contacts become known, their actuation in the field of a solenoid he follows. As a result of the inclusion of these contacts in a glass tube, they are turned into their function is not disturbed by dust or aggressive gases, so that they do not require maintenance work reliably even after long breaks in operation.

Wegen der kleinen bewegten Masse arbeitet der Kontakt schnell, und da er außerdem bei einer recht genau definierten Feldstärke schließt, eignet er sich auch für Uberwachungszwecke, und zwar insbesondere zur Überwachung von elektrischen Leitern, vorzugweise Kabeln. Neuerung Ùm dies zu ermöglichen, wird der Kontakt gemäß der ohne Verwendung der. sonst zu seiner Betätigung erforderlichen Magnetspule in dem den oder die Leiter umgebenden Kraftlinien- feld angeordnet.Because of the small moving mass, the contact works quickly, and since it also closes at a very precisely defined field strength, it is also suitable for monitoring purposes, in particular for monitoring electrical conductors, preferably cables. innovation To make this possible, contact will be made in accordance with the without using the. otherwise necessary for its operation Magnet coil in the line of force surrounding the conductor or conductors field arranged.

In der Figur 1 ist ein Ausführungsbeispiel gezeigt, bei dem der Kontakt 1 in dem das Einleiterkabel 2 umgebenden Kraftlinienfeld 3 liegt. Bei einer bestimmten Stromstärke wird der Kontakt 1 betätigt, so daß er einen Überwachugszwecken dienenden Signalstromkreis schließt. Zur Einstellung des gerünschten Ansprechstromes kann zusätzlich ein in seiner Lage veränderbarer magnetischer Nebenschluß, z. B. der Eisenstab 4, verwendet werden. Es kann auch die Lage des Kontaktes 1 selbst gegenüber dem Einleiterkabel veränderlich sein, indem der Abstand oder der Kreuzungswinkel einstellbar ist. Es kann auch ein Schirmblech 5 zwischen Kabel und Kontakt einschiebbar sein.In the figure 1 an embodiment is shown in which the contact 1 in the force line field 3 surrounding the single conductor cable 2. With a certain Amperage of the contact 1 is operated so that it serves a monitoring purpose Signal circuit closes. To set the desired response current, In addition, a magnetic shunt that can be changed in its position, e.g. B. the Iron rod 4, can be used. It can also be the position of the contact 1 itself opposite the single core cable can be changed by changing the distance or the crossing angle is adjustable. A shield plate 5 can also be inserted between the cable and the contact be.

Verwendet man den Kontakt bei einem Mehrleiterkabel, um z. B. zu melden, daß die Summe der das Kabel durchfließenden Ströme nicht mehr Null ist, also ein fehlerhafter Zustand eingetreten ist (Erdschluß, Phasenunterbrechung bei parallelgeschalteten Lei. tern), so kann man das Ausführungsbeispiel der Figur 2 anwenden. Der Kontakt 1 liegt dann in dem das Mehrleiterkabel 6 umgebenden Kraftlinienfeld 3. Außerdem ist der Eisenrückschluß 7 vorhanden, damit der Ansprechzeit unabhängig von der räumlichen Lage der gestörten Phase zum Kontakt 1 ist. Der Ansprechwert kann auch hier durch weitere Mittel, z. B. den verschiebbaren Bisenstab 4 o.dgl., beeinflußt werden.If you use the contact in a multi-conductor cable to e.g. B. to report that the sum of the currents flowing through the cable is no longer zero, i.e. one a faulty state has occurred (earth fault, phase interruption in the case of parallel-connected Lei. tern), the exemplary embodiment in FIG. 2 can be used. The contact 1 then lies in the force line field 3 surrounding the multi-conductor cable 6 the iron back yoke 7 is present, so that the response time is independent of the spatial Position of the disturbed phase to contact 1. The response value can also go through here other means, e.g. B. the slidable Bisenstab 4 or the like. Be influenced.
