Definitions

  • DE-A-3 705 918 discloses an electromagnetic relay with one Magnet system, the only coil of which is U-shaped overall Iron part is penetrated.
  • One leg of the iron part is divided into two parts, so that on the same side of the coil two parallel magnetic circuits with an assigned hinged anchor each. The order is to ensure that when the anchor is driven Contact welded, the entire magnetic flux through this armature and therefore the other armature the next time the coil is excited can no longer close.
  • This relay allows two circuits to switch in a way independently of each other; the separation but is not sufficient to meet the security requirement mentioned at the beginning to fulfill.
  • An electromagnetic relay is known from AT-B-221 148, at which is a coil of a shell-shaped one made up of two parts Yoke is surrounded. Each yoke part is made from a stamped and bent Sheet metal piece built up. Flags are formed on both yoke parts Push the inside of the coil parallel to each other. On each of the Yoke parts are one or more that work synchronously when the coil is excited Folding anchors arranged. Such a relay is for the aforementioned two-channel control in safety switchgear neither determined still suitable.
  • the invention is based on the general object, disadvantages, such as similar magnetic systems for electromagnetic relays the state of the art occur to at least partially eliminate. A more special task can be seen in a magnet system for one Relay indicate that the construction of a safety circuit at low Coil power loss allowed.
  • the development according to claim 5 means a spatially uniform Utilization of the magnetic flux of the coil with low leakage flux and thus a further optimization regarding coil losses.
  • the polarized version according to claim 6 is for the use of the magnet system useful for many relay applications.
  • the embodiment according to claim 13 gives the additional advantage a defined order in tightening the two anchors. For example can the anchor with the lower sensitivity to actuation a contact designed only for guiding the load current his. At the same time, faulty control by the sole Response of the more sensitive armature recognized.
  • the different Response sensitivities can be caused by different magnetizations or spring characteristics or asymmetrical coil windings or by combining these measures.
  • FIG. 1 a shows schematically the conditions when using two relays, each of which has an iron part 15, 16 with a square cross section , an extrusion coating 17 and a coil 18 .
  • each coil Given a certain ampere winding number of the coil 18 and a corresponding cross-sectional area of the iron part 15, 16 (which is dimensioned such that the iron does not become saturated), each coil has a power consumption of 500 mW, which results in a total power of 1000 mW results.
  • Fig. 1b shows the situation with a relay approximately according to the prior art according to US-A-4,833,435.
  • FIG. 1c The design according to the invention, illustrated schematically in FIG. 1c, in which the two iron parts 15, 16 with a square cross section are moved close together, results in a coil 18 with a rectangular cross section and a power consumption of around 650 mW.
  • FIGS. 1d and 1e are further optimized insofar as the cross-sectional area of the coil 18 is further reduced with the same cross-sectional area of each iron part and thus the power consumed by it is reduced.
  • 1d shows two iron parts 15 ', 16' with a rectangular cross section , which give a square overall cross section and lead to a power consumption of the coil 18 of approximately 625 mW, while the circular overall cross section of the iron part arrangement 15 ", 16" selected according to FIG. 1e leads to a coil 18 with a power consumption of only 595 mW.
  • the magnet system shown in FIG. 2 has two iron parts 20, 21 , the middle legs of which run parallel and at a distance s from one another and together pass through two coils 22, 23 arranged along the same axis.
  • the two coils 22, 23 are wound on a common coil body 24 with an insulating central flange 25 .
  • the legs 26, 27 of the iron part 20 protruding from the coil body 24 and the corresponding legs 28, 29 of the iron part 21 run in opposite directions and are bent upwards at their ends to form pole pieces 30 ... 33 .
  • a rotating armature 34 is pivotally mounted about its vertical central axis.
  • the rotary armature 34 lies with its large armature pole faces 35, 36 against the pole shoes 30, 31 of the iron part 20 .
  • 33 of the other iron piece 21 is between the pole pieces 32, mounted a rotary armature 37 about its vertical central axis of swiveling, in the rest position with its large Ankerpol vom 38, 39 abuts the pole pieces 32.
  • the coils 22, 23 as well as the iron parts 20, 21 have the same structure and are arranged symmetrically to one another.
  • the rotary anchors 34, 37 are also constructed and arranged in the same way, but the rotary anchor 34 has a higher sensitivity than the rotary anchor 37. This will be discussed in more detail below in connection with FIG. 4.
  • the iron parts 20, 21 and the coils 22, 23 can also be dimensioned asymmetrically.
  • both coils 22, 23 are excited. Their equally strong magnetic fluxes generated in the same direction are divided between the two iron parts 20, 21 , so that half of the total magnetic flux generated is available for actuating each rotary armature 34, 37 .
  • These are pivoted counterclockwise by the forces acting between the pole pieces 30, 31 and the small armature pole faces 40, 41 of the left armature 34 in FIG. 3 or between the pole pieces 32, 33 and the small armature pole faces 42, 43 of the right armature 37 been and now take the position shown in Fig. 3.
  • FIG. 4 shows the state in which only the coil 22 or only the coil 23 has been excited.
  • the magnetic flux generated by the excited coil 22 or 23 is divided, as before, onto the two iron parts 20, 21 essentially uniformly.
  • the higher response sensitivity assumed for the left rotating armature 34 is generated in the exemplary embodiment in that the permanent magnets 46, 47 arranged between two armature plates 44, 45 , which hold the rotating armature 34 in its rest position, are smaller or weaker than those in the right rotating armature 37 permanent magnets 48, 49 arranged at corresponding points .
  • the magnetic fluxes generated by the coils 22, 23 and the strength of the permanent magnets 46 ... 49 are selected so that when only one coil 22 or 23 is excited, only the left rotary armature 34 attracts with the higher sensitivity, while the less sensitive right armature 37 remains in its rest position.
  • This switch position can be detected, for example, by contacts (not shown) actuated by the armatures. These contacts are actuated via actuators (not shown) which rest on actuating pieces 50... 53 formed on the armature.
  • the asymmetry in the switching behavior of the two rotary armatures 34, 37 explained with reference to FIG. 4 does not only mean that only one of the rotary armatures responds when only one of the two coils 22, 23 is excited , for example in the event of a faulty triggering. It also leads to the fact that at the start of the excitation of both coils 22, 23, first the left rotary armature 34 and only then does the right rotary armature 37 pivot into the working position. This behavior can be used to actuate the contacts that switch the load current with the later rotating armature 37 .
  • both rotary armatures 34 and 37 have been moved into the working position shown in FIG. 3 when both coils 22 and 23 are excited, one of the two coils 22 or 23 can be switched off.
  • the reduced magnetic flux generated by the coil remaining excited is sufficient to hold the armatures 34, 37 in their working position.
  • the magnetic flux of each of the two coils could be reduced by connecting a holding contact (make contact) in the coil excitation circuits, thereby reducing the power loss.
  • the 5 to 8 comprises a coil 59, the coil body 60 of which is penetrated by two C-shaped iron parts 61, 62 .
  • the middle sections of the iron parts pass through the coil 59 in parallel and at a short distance s from one another.
  • the two legs of the iron part 61 form an upper pair of front coil pole surfaces 63, 66 in FIG. 5 and an upper pair of rear coil pole surfaces 64, 65 ;
  • the legs of the iron part 62 form a lower pair of front coil pole surfaces 63 ', 66' and lower pair of rear coil pole surfaces 64 ', 65'.
  • the coil 59 is surrounded by a two-part bobbin case, the upper half constitutes 67 an upwardly projecting bearing pin 68 while with respect to the upper half 67 identically shaped lower half 67 'a downwardly extending, coaxial with the bearing pin 68 bearing pin 68' carries.
  • An overall approximately H-shaped upper or lower armature 70, 70 ' is mounted rotatably about the respective journal 68, 68' .
  • the armature 70 contains two armature plates 71, 72 (see also FIG. 8) forming the parallel legs of an H-shape, between which two permanent magnets 73, 73 ' are arranged.
  • the anchor parts 71 ... 73 are held together by a plastic sheath 74 largely enclosing them.
  • the lower armature 70 ' is identical to the upper armature 70 , the large armature pole faces 75', 76 ' facing the longitudinal center plane of the armature 70' facing the coil pole faces 63 ' and 64' of the iron part 62 . Because of the identical design of the two armatures 70, 70 ' , the opposite polarization of the permanent magnets 73, 73' indicated in FIGS. 6 and 8 results .
  • the magnet system according to FIGS. 5 to 8 has two magnetic circuits , one of which has the iron part 61 with the upper coil pole faces 63, 64, 65 and 66 and the upper armature 70 and the other the iron part 62 with the lower ones Contains coil pole faces 63 ', 64', 65 ' and 66' and the lower armature 70 ' .
  • the magnetic circuits formed in this way lie in planes distributed around 180 ° around the coil axis (in this case, therefore, in the same geometrical plane).
  • the exemplary embodiment according to FIGS. 5 to 8 shows a monostable version of the magnet system.
  • the large armature pole surfaces 75, 76 rest on the upper coil pole surfaces 63, 64 and the large armature pole surfaces 75 ', 76' on the lower coil pole surfaces 63 ', 64' .
  • the coil 59 is acted on in such a way that it generates an S pole on the coil pole surfaces 63, 63 ', 65, 65' and an N pole on the coil pole surfaces 64, 64 ', 66, 66' , the two armatures 70 , 70 ' pivoted in the opposite direction of rotation in their working position until the small armature pole surfaces 77, 78 of the armature plates 71, 72 on the coil pole surfaces 65, 66 and the small armature pole surfaces 77', 78 ' of the armature plates 71', 72 ' on the coil pole surfaces 65' , 66 ' .
  • each armature 70, 70 ' actuates two contact springs, for example, in such a way that in each armature position one relay contact is open and one is closed.
  • the armatures 70, 70 ' return to the rest position shown in FIG. 7, because the attractive forces between the coil pole surfaces 63, 64, 63', 64 ' and the large armature pole surfaces 75, 76, 75 ', 76' are substantially larger than between the coil pole surfaces 65, 66, 65 ', 66' and the small armature pole surfaces 77, 78, 77 ', 78'.
  • the aforementioned counter-rotation of the two armatures 70, 70 ' when switching the coil 59 on and off means that the forces and torques occurring in the magnet system cancel each other out, so that no forces are transmitted to the outside when actuated.
  • the housed in the anchors Permanent magnets can also be poled in the same direction, the armature then perform the same rotating movements when the coil is excited. In this case it is also possible to mechanically connect the two anchors to couple.
  • FIG. 9 relates to a magnet system which can be constructed in a manner similar to that in FIGS. 5 to 8, but has four rotary armatures 80, 80 ', 81, 81' arranged at 90 ° around the coil axis. As indicated, each of the rotary anchors contains two anchor plates 82 and a permanent magnet 83 arranged between them .
  • the coil 84 is traversed in the axial direction by four C-shaped iron parts 85, 85 ', 86, 86' , the central sections of which are each designed in the shape of a sector of a circle and together the inner cross section of the coil 84 apart from one another with small distances and a (not shown) completely fill out the extrusion coating.
  • the yoke legs 87, 87 ', 88, 88' emerging from the coil 84 and running perpendicular to the coil axis lie between the ends of the respective anchor plates 82.
  • the magnet system thus has four magnetic circuits, each of which contains one of the iron parts 85, 85 ', 86, 86' passing through the same coil 84 and one of the rotary anchors 80, 80 ', 81, 81' .
  • the magnetic circuits formed in this way lie in planes distributed around 90 ° around the coil axis (ie in two geometrical planes).
  • the coil 90 is penetrated by two C-shaped iron parts 91, 91 ' , the respective coil pole faces 92, 92' and 93, 93 'of which point in opposite directions.
  • the central sections lying inside the coil 90 are designed in such a way that they complement each other to form a square overall cross section according to FIG. 1d.
  • a permanent magnet 94 which is parallel to the axis of the coil 90 and is magnetized in such a way that it has a central N pole and an S pole at both ends thereof.
  • a rod-shaped armature 95 is pivotally mounted in such a way that it touches the respective coil pole surface 92 or 93 with one of its ends in its two end positions.
  • the magnet system shown in FIG. 10 has like that of FIGS. 5 to 8 two magnetic circuits, in planes distributed by 680 ° around the coil axis (i.e. in the same geometric plane).
  • the armature 95 is held in the end position shown by the magnetic flux of the permanent magnet 94 . If the coil 90 is acted upon in such a way that it generates an N pole on the coil pole surface 92 , the left end of the armature 95 in FIG. 10 is repelled by the coil pole surface 92 and the armature is switched into its opposite position for contact with the coil pole surface 93 , on which it is held by the permanent magnet 94 after the coil 90 has been switched off.
  • the magnet system according to FIG. 10 can also be unpolar. With such a design, the permanent magnets 94, 94 ' are omitted , and the armatures 95, 95' are not pivotally mounted about their center but around one end on the respective coil pole surface.
  • magnet systems with three or more than four magnetic circuits distributed equally around the coil axis are also conceivable.
  • the spatially distributed and uniform arrangement of the iron parts means that the magnetic flux generated by the coil is used several times with the lowest possible coil power loss. The mutual influence of the individual magnetic circuits is negligible, and the stray fluxes are minimized. LIST OF REFERENCE NUMBERS 15, 16 hardware 63 ...
