Abstract
The utility model discloses a high-voltage ac magnetic holding relay, which is composed of an electromagnetic system, a contact system, and a base. A fixed contact is arranged in the base; magnetic steel and two armatures are connected and are combined to be an 'H' shape; one armature is connected with pole shoes of the electromagnetic system; the other armature is connected with a push-pull rod of the contact system; the push-pull rod is connected with the free end of a high elasticity reed which is provided with a spring and a movable contact, and the other end is connected with the base. Because of adoption of strong magnetic technique, high-voltage driving technique, voltage control technique of an AC network, and other technique, accordingly, the high-voltage ac magnetic holding relay can be applied to an ac single-phase circuit, a dc single-phase circuit, an ac three-phase circuit, and a dc three-phase circuit.
Description
The utility model relates to a kind of electric component, especially relay.
The contact load under the 250VAC condition of present domestic magnetic latching relay is 30A, 50A, 60A, 100A etc., is single-phase, does not still have the magnetic latching relay of three-phase.The foreign technology leader is a German GRUNER company, and the contact load capacity is (under the 250VAC condition), and single-phase 8A, 10A, 16A, 20A, 25A, 40A, 60A, 100A, 200A, three-phase are 63A, 80A.From these product analyses, its technological deficiency that mainly exists has (1) contact resistance big, and (2) action is unreliable, and open apart from little (3), and (4) contact area is little etc., therefore, during use, causes consequences such as stuck, electrical breakdown, loose contact, poor reliability easily.
The purpose of this utility model be overcome above-mentioned defective and improve the design a kind of compact conformation, the assembling simple, widely used high performance high-voltage alternating magnetic latching relay.
The utility model is by electromagnetic system, contact system and pedestal constitute, magnet steel and two synthetic " worker " fonts of armature associative sets, between the coil of electromagnetic system and pedestal, be provided with pole shoe, armature and pole shoe link, and the pull bar of another armature and contact system links, and pull bar links with the free end that is provided with the reed of spring and moving contact, the other end and the pedestal of reed link, and are provided with on pedestal and decide contact.
Is provided with movable little axle in the middle of the described magnet steel, thereby makes magnet steel drive free to rotate pull bar make the reed moving contact and decide contact and contact.
Described contact system is provided with at least one pair of above fixed, contact of living, and deciding contact is planar structure, and moving contact is a cylindrical surface structure, to increase contact area and touch.
Described magnet steel adopts ndfeb magnetic material, and reed adopts the beryllium-bronze highly elastic material to make, to guarantee strong magnetic confining force being arranged and increase contact pressure.Because the utility model adopted above technology, it is reasonable to make this magnetic latching relay have a compact conformation, the assembling simple and fast, and work efficiency improves, and is of many uses, but and has high voltage drive and a directly actuated advantage of ac grid voltage.
Description of drawings:
Fig. 1 is the utility model high-voltage alternating magnetic latching relay structure principle chart,
Fig. 2 is power supply, control, the protective circuit figure of the utility model high-voltage alternating magnetic latching relay.
Below in conjunction with accompanying drawing the utility model is described in further detail:
The utility model high-voltage alternating magnetic latching relay is by electromagnetic system, control system and pedestal constitute, on the magnet steel of making by ndfeb magnetic material (3), be associated with 2 armature (10), be combined into " worker " font, be provided with movable little axle in the middle of the magnet steel (3), between the coil (1) of electromagnetic system and pedestal (4), be provided with pole shoe (2), armature and pole shoe (2) link, the pull bar of another armature and contact system (9) links, the free end of making reed (5) by the beryllium-bronze highly elastic material that pull bar (9) is provided with spring (7) and moving contact (8) links, the other end of reed (5) and pedestal (4) link, be provided with in the bottom of pedestal (4) can with moving contact (8) adhesive decide contact (6), in order to increase contact area, adopt the line way of contact, promptly deciding contact is planar structure, and moving contact is a cylindrical surface structure; In order to increase contact force, can be provided with in contact system more than 2 pairs has the moving contact of deciding, and when having more than two pairs, adopts the moving contact linkage manner, to guarantee synchronism.Because deciding contact, moving contact, line bag, pole shoe, armature, pushing drawing rod etc. all is separate piece, do not form integrated part, insert pedestal during installation respectively, even magnetic latching relay is in thermal environment or contact heating, can not produce the distortion of other part and stuck or move dumb yet, according to different load currents, increased contact area, adopt ferromagnetism NdFeB material and high resiliency beryllium-bronze material to make magnet steel and reed, thereby guarantee to have strong magnetic confining force, increase contact pressure, also cushioned spring, also be difficult for producing electric arc.Accompanying drawing 2 explanation can adopt high voltage to the power supply of line bag, and voltage to 515VDC, guarantees to have enough actuating forces from 96VDC, directly employing line voltage rectification of power supply circuits, needn't be through the transformer conversion, to the magnetic latching relay of unidirectional application.220VAC half-wave or full-wave rectification.Magnetic latching relay to three-phase applications; adopt three-phase and four-line direct half-wave of line voltage 3 * 220V/380V or full-wave rectification power supply; also can adopt parallel operation after A, B, the full-wave rectification of C phase; adopt the hot resist technology of PTC; control signal can be used ac grid voltage; certainly, also power supply circuits, control circuit, PTC thermal protection circuit and magnetic latching relay can be made into one, convenient reliable.But this high-voltage alternating magnetic latching relay has high voltage drive and the directly actuated advantage of ac grid voltage, can widen application greatly, is a kind of desirable substitute products, has vast market prospect.
