Abstract
The utility model relates to the electric field and particularly relates to an electromagnetic release. According to a technical scheme, the electromagnetic release comprises a casing, a magnetic yoke, a magnetic steel, an armature and a coil, wherein the magnetic steel is fixed on the magnetic yoke, and one end of the armature is movably connected with the magnetic yoke. The electromagnetic release is characterized in that the magnetic yoke is provided with a fixed rod, the coil is sleeved at an outer wall of the fixed rod, and the magnetic steel is prepared by a ferro-nickel aluminum material. The electromagnetic release is advantaged in that the special-purpose fixed rod is arranged, so the coil and the magnetic yoke are more securely fixed, the ferro-nickel aluminum material is further employed, a suction force of the magnetic steel is greatly improved, magnetic flux is improved, and thereby a holding force between the armature and the magnetic yoke is improved integrally, use requirements are met, structure layout is reasonable, and stability of an electric leakage action current is improved.
Description
Technical field
The utility model relates to electric field, refers to especially a kind of electromagnetic release.
Background technology
Electromagnetic release is a kind of of release; it only provides the magnetic protection; short-circuit protection namely, it is actually a magnetic Hui Li, thereby the magnetic field force produced when electric current is enough large overcomes the reaction spring adhesive armature, hits the action of draw bar lead agency and cuts off circuit.The patent No. is that CN200920302449.3 discloses a kind of electromagnetic dual top post releaser, comprise housing, be provided with strutting piece in described housing, described strutting piece one side is fixed with magnet steel, its opposite side is inserted in trip coil, also fix armature is arranged on the locating button of described strutting piece, and connect described armature by spring, described armature below is connected with two push rods; Be connected inconvenience between the release coil of this structure and strutting piece, cause unreasonable structure, and the suction that existing magnet steel produces is less, in use the confining force between armature and strutting piece is inadequate to cause electromagnetic release, do not reach instructions for use, cause topology layout unreasonable, thereby cause the stability that has reduced residual operating current.
The utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of confining force greatly and the rational electromagnetic release of topology layout.
The technical solution of the utility model is achieved in that a kind of electromagnetic release, comprise case, yoke, magnet steel, armature and coil, described magnet steel is fixed on yoke, one end of described armature and yoke are flexibly connected, it is characterized in that: on described yoke, be provided with fixed lever, coil is sheathed on the outer wall of this fixed lever, and described magnet steel is made by aluminium nickel cobalt material.
By adopting technique scheme, the fixed lever of coil special use is set, make fixing more firm between coil and yoke, and adopted aluminium nickel cobalt material, greatly increased the suction of magnet steel, increased magnetic flux, thereby improved on the whole the confining force between armature and yoke, meet instructions for use, topology layout is reasonable, thereby has improved the stability of residual operating current.
The utility model further is set to: the end of described fixed lever is positioned on the free-ended motion path of armature, and the mating surface of the face area of fixed lever and armature is suitable.
Be preferably, on described case, slidably connect push rod, this push rod is positioned on the motion path of armature.
By adopting technique scheme, the magnetic force of magnet steel is collected on the end face of fixed lever, greatly improved the confining force between yoke and armature, topology layout is more reasonable.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model embodiment structural representation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model discloses a kind of electromagnetic release, comprise case 1, yoke 2, magnet steel 3, armature 4, coil 5, strutting piece 6 and spring 7, this case 1, yoke 2, magnet steel 3, armature 4, coil 5 and strutting piece 6 all are positioned at case inside, described magnet steel 3 is fixed on yoke 2, and the two ends of strutting piece 6 are connected on magnet steel 3 and yoke 2, the end that strutting piece 6 is connected with yoke 2 is provided with locating button, the link 41 of armature embeds this location buckle, and the link 41 of this armature is connected in an end of spring 7, the other end of spring 7 is connected in the junction of strutting piece 6 and magnet steel 3, the link 41 of armature can rotate around strutting piece 6 and the junction of yoke 2, in the utility model specific embodiment, be provided with fixed lever 21 on described yoke 2, coil 5 is sheathed on the outer wall of this fixed lever 21, described magnet steel 3 is made by aluminium nickel cobalt material, and be aluminium nickel cobalt 8 classes, the trade mark is FING28, the fixed lever of coil special use is set, make fixing more firm between coil and yoke, and adopted aluminium nickel cobalt material, greatly increased the suction of magnet steel, increased magnetic flux, thereby improved on the whole the confining force between armature and yoke, meet instructions for use, topology layout is reasonable, thereby improved the stability of residual operating current.
In the utility model specific embodiment, the end of described fixed lever 21 is positioned on the motion path of free end 42 of armature, and the mating surface of the face area of fixed lever 21 and armature 4 is suitable, the mating surface that is armature is covered on the end face of fixed lever, slidably connect push rod 8 on described case 1, this push rod 8 is positioned on the motion path of armature 4, the magnetic force of magnet steel is collected on the end face of fixed lever, greatly improved the confining force between yoke and armature, topology layout is more reasonable.
Operation principle: the armature on electromagnetic release by the permanent magnetic attraction sticking of direct current that permanent-magnet steel produced on yoke.Suction not only will overcome the counter-force of retracting spring to armature, but also enough large confining force will be provided.When zero-sequence transformer secondary output current when the electromagnetic release coil, just on armature superposition an interchange suction.The suction opposite direction that it has half period and permanent-magnet steel to produce, when its peak value meets and exceeds confining force, armature just discharges under the counter-force effect of retracting spring, thereby promote operating mechanism, plays creepage protection function.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
