Abstract
The utility model discloses a low-loss anti-interference magnetic latching electromagnetic switch element. The low-loss anti-interference magnetic latching electromagnetic switch element comprises an electromagnetic coil, an armature is inserted in a mesopore of the electromagnetic coil, and an insulating transmission rod (3) is connected with the armature (2), and matches a switch element. A permanent magnet (4) of which the magnetic pole points to a cylindrical surface of the armature (2), is arranged on the electromagnetic coil, a yoke (5) is sleeved on the side part and the exterior of the electromagnetic coil (1) which is equipped with the permanent magnet (4), and the magnetic pole at the other end of the permanent magnet (4) is contacted with the yoke (5). Because the special action process of the utility model, the anti-external field interference demands of a power system, especially of an intelligent electric meter, can be satisfied very well. Because the yoke, the armature and the permanent magnet form an enclosed loop structure, the enclosed loop structure enables the anti-external field interference capability to be improved. Moreover, by controlling the air gap of a magnetic circuit and distributing parts scientifically and reasonably, the coil driving efficiency and the anti-interference capability of the external reinforcing permanent magnet are improved.
Description
Technical field
The utility model relates to the jamproof magnetic of a kind of low damage and keeps the electromagnetic switch element, belongs to the electromagnetic switchgear technical field.
Background technology
Existing magnetic keeps the electromagnetic switch element in use to have the following disadvantages:
1, existing magnetic keeps the electromagnetic switch element to adopt open double-bridge structure, very easily is subject to outer magnetic force impact, hinders the magnetic potential in the doube bridge air gap, cause coil stimulating after armature be failure to actuate;
2, design minimum driving stroke for satisfying Double-bridge type, Double-bridge type design needs larger air gap, and flux loss is larger, and coil drive efficient is low, and when strengthening outside permanent magnet and disturbing, this phenomenon is more obvious even directly cause being failure to actuate; Relay or switch that this kind magnetic keeps the electromagnetic switch element to form, it is used in the electric power system ammeter, and some can utilize this phenomenon power stealing, and this phenomenon is freeed often;
3, existing magnetic keeps in the design of electromagnetic switch element, and the assembling of mobile armature part is very tired multiple, and needs can be shaped by the mold insert injection moulding, easily causes the deviation of different die cavity armature portion sizes.In practical set since magnetic circuit movably, the reference for assembling of movable parts is different, thereby cause fully closure of armature, reduced product magnetic confining force.
4, existing process conditions can't solve the dimension precision requirement of permanent magnet element and other part, only can solve by different die cavitys cooperations, renewal part, cause conformity of production poor, and human cost is high, and element precision requires high.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of simple in structure, antijamming capability is strong, drive efficiency is high, the magnetic maintenance electromagnetic switch element of the anti-outer magnetic disturbance that loss is low can overcome the deficiencies in the prior art.
The technical solution of the utility model is: the jamproof magnetic of low damage keeps the electromagnetic switch element, and it comprises solenoid, is inserted with armature in the mesopore of solenoid, is connected with insulating driving rod at armature, and insulating driving rod cooperates with switch element; At solenoid the permanent magnet that magnetic pole points to the armature cylinder is housed, the outer cover that reaches at the solenoid sidepiece that is provided with permanent magnet has yoke, and the other end magnetic pole of permanent magnet contacts with yoke.
Permanent magnet is installed in middle part one side, both sides of solenoid or all around.
Compared with the prior art: the utility model is installed the permanent magnet of magnetic pole vertical coil at the solenoid middle part, the armature of pegging graft in coil, and outside coil and permanent magnet, yoke is set, like this in the situation that not energising, because an end magnetic pole of permanent magnet contacts with yoke, according to the magnetic conduction principle, magnetic is with the derivative two ends to solenoid of yoke, according to matching requirements, promote armature armature is contacted with the yoke of solenoid top or bottom; Behind installing insulating drive link on the armature, can make itself and electric component realize that magnetic keeps.In the situation that solenoid energising, the inner magnetic field that produces of solenoid, be placed on the armature magnetic polarization in the solenoid, when the yoke magnetic pole that the armature magnetic pole of fitting when coil one end yoke and permanent magnet derive was reverse, armature was kept original position, the electric elements action remains unchanged, when magnetic pole was identical, according to the homopolar-repulsion principle, armature was subjected to the repulsive force effect, armature motion is finished the electric elements switch motion to coil.Because of special action process of the present utility model, for electric power system, particularly the anti-external magnetic field interference demand for intelligent electric meter is well positioned to meet, because the synthetic closed loop structure of yoke, armature and set of permanent magnets, this closed loop structure has improved anti-external magnetic field interference performance, and by to control and the scientific and reasonable distribution of each parts of magnetic air gap, improved coil drive efficient and added the antijamming capability of strong permanent magnetic body, loss is reduced; Simultaneously relatively existing magnetic maintenance electromagnetic switch structure is simpler, cost of manufacture is lower, and the assembling consistency is high, driving force is strong.
The utility model also has following characteristics
1. the utility model is integrated into the electromagnetic switch element part of in the past discrete existence in the unified parts, simplify the assembly difficulty of armature part and cancelled the mold insert injection moulding, common reference for assembling is so that magnetic keeps the consistency of electromagnetic switch element to be guaranteed, and on the magnetic confining force, surmount existing magnetic maintenance electromagnetic switch element far away, reached with minimum part and the simplest and the most direct assembling mode and made the purpose that magnetic keeps the electromagnetic switch element.
2. the utility model adopts the built-in bistable magnetic circuit of screwed pipe, air gap is little, the magnetic flux that acts on armature under the equal coil power dissipation improves several times, and its anti-external magnetic field interference performance has reached with lower energy consumption and the lower purpose that becomes originally to reduce outer magnetic influence far above existing product.
