Temperaturkompensation für hochempfindliche permanentraagnetische HaftrelaisTemperature compensation for highly sensitive permanent magnets Latching relay

Die Erfindung betrifft eine Temperaturkompensation für hochempfindliche permanentmagnetische Haftrelais gemäß dem Oberbegriff des Anspruches 1.The invention relates to a temperature compensation for highly sensitive permanent magnetic hold-open relay according to the preamble of claim 1.

Derartige Relais bestehen in ihren wesentlichen Konstruktionsmerkmalen aus einem Permanentmagneten und daran anliegendem Magnetjoch, sowie einem Anker und eine den Haltefluß des Permanentmagneten beeinflussenden Erregerwicklung. Zum Erreichen einer hohen Ansprechempfindlichkeit ist es unter anderem begannt, den magnetischen Luftspalt möglichst klein zu halten. Bagagen ist es bisher noch nicht gelungen, die Ansprechempfindlich'.ceit solcher Relais von der Umgebungstemperatur unabhängig zu machen. Naturgemäß wirkt die Umgebungstemperatur auf die Ansprechschwelle derart ein, daß bei hohen Temperaturen der Erregerstrom steigt, was zur Folge hat, daß das Relais bei einem anderen als dem eingestellten Uert anspricht. Dies ist aber von der Zielsetzung eines verläßlich arbeitenden Relais dieser Art nicht erwünscht, ja sogar oft von den Vorschriften her unzulässig.Such relays consist in their essential design features of a permanent magnet and magnetic yoke adjacent to it, as well as an armature and an excitation winding which influences the holding flux of the permanent magnet. In order to achieve a high response sensitivity, one of the things that began is to keep the magnetic air gap as small as possible. Bagagen has not yet succeeded in making the response sensitivity of such relays independent of the ambient temperature. Naturally, the ambient temperature acts on the response threshold in such a way that the excitation current increases at high temperatures, with the result that the relay responds at a value other than the set value. However, this is not desirable from the objective of a reliably operating relay of this type, and even often inadmissible from the point of view of the regulations.

Der Erfindung liegt daher die Aufgabe zugrunde, bei einem permanentmagnetischen Haftrelais gemäß dem Oberbegriff des Anspruches die Ansprechschwelle solcher Relais von der Umgebungstemperatur unabhängig zu machen, bzw. den magnetischen Haftflu3 durch Temperatureinwirkung zu beeinflussen.The invention is therefore based on the object of a permanent magnetic Sticky relay according to the preamble of claim the response threshold of such relays from the ambient temperature to make it independent, or to influence the magnetic adhesive flux through the influence of temperature.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Anspruches 1 angegebenen Maßnahme gelöst. Weitere Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.This task is carried out by the characterizing part of the claim 1 resolved. Further refinements of the invention can be found in the subclaims.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird die Erfindung näher erläutert. Es zeigt:The invention is explained in more detail using an exemplary embodiment shown in the drawing. It shows:

Haftrelais,Latching relay,

- Fig. 2 - die Magnetflußlinien im erfindungsgemäßen Haftrelais.- Fig. 2 - the magnetic flux lines in the latching relay according to the invention.

Gemäß Figur 1 besteht das Haftrelais im wesentlichen aus einem Magnetjoch mit den beiden Schenkeln 1, 2 und dem Nebenschluß 3. Mit 4 wird der Anker bezeichnet, der mittels einer leder 5 vorgespannt ist. Auf einem der Schenkel 2 ist eine Errcjerspule 6 angeordnet. Das Magnetjoch hat im Bereich des Nebenschlusses 3 einen Permanentmagneten 7. Die erfindungsgemäße Thermolegierung zur Kompensation der Temperatur ist zwischen den Polen "N11 und 11S" des Permanentmagneten 7 und dem Magnet j och-Nebenschiuß 3 angeordnet.According to FIG. 1, the latching relay consists essentially of a magnetic yoke with the two legs 1, 2 and the shunt 3. The armature 4 is designated, which is pretensioned by means of a leather 5. A detection coil 6 is arranged on one of the legs 2. The magnet yoke has a permanent magnet 7 in the area of the shunt 3. The thermal alloy according to the invention for compensating the temperature is arranged between the poles "N 11 and 11 S" of the permanent magnet 7 and the magnet yoke shunt 3.

Anhand der Darstellung in Figur 2 wird die Wirkungsweise der Erfindung näher erläutert.The mode of operation of the invention is illustrated in FIG. 2 explained in more detail.

Die Abnahme des Magnetflusses ΦΜ durch Verringerung der Dcuermagnetinduktion kann diese Erhöhung nur geringfügig kompensieren. Sind nun Scheiben 8 aus dem vorgeschlagenen Material in den Dauermagnetkreis, bestehend aus Dauermagnet 7 und Magnetjoch-Nebenschluß 3 eingefügt, so wird sich in dem Maße der Temperaturerhöhung der magnetische Widerstand der Scheiben aus Thermolegierung kontinuierlich vergrößern, so daß der magnetische Fluß j)M des DauermagnetenIncrease conclusion 3 and the resulting increase in the adhesive flux (j) H and increase in the coil resistance. The decrease in the magnetic flux Φ Μ due to the decrease in the Duermagnetinduktion can only slightly compensate for this increase. If disks 8 made of the proposed material are now inserted into the permanent magnetic circuit, consisting of permanent magnet 7 and magnetic yoke shunt 3, the magnetic resistance of the thermal alloy disks will increase continuously as the temperature increases, so that the magnetic flux j) M des Permanent magnets

Dadurch wird der Haltefluß (J) im Ankerkreis — Anker, Schenkel 1, 2, Magnetjoch-Nebenschluß 3 ebenfalls kleiner, so daß der ursprüngliche Ansprechwert wieder erzielt wird.is reduced accordingly by the yoke shunt 3. As a result, the holding flow (J) in the armature circuit - armature, leg 1, 2, yoke shunt 3 also smaller, so that the original Response value is achieved again.

Durch die Auslegung der Scheibe bezüglich der Stärke, und durch die Wahl einer geeigneten Thermolegierung, gekennzeichnet durch ihren Curiepunkt und die Steigung, läßt sich so die kompensierende Wirkung der Scheibe genau einstellen.Through the design of the pane in terms of strength and through the choice of a suitable thermal alloy, characterized by its Curie point and the slope, the compensating effect of the disc can be precisely adjusted.
