The utility model needs no silicon sheets, and has no alternating-current noise under on-state and no temperature rise, and consumes tiny power.
Description
Technical field:
The utility model relates to control apparatus, a kind of A.C. contactor that is used for frequently switching on and off at a distance major loop and big volume controlled loop of more specifically saying so.
Background technology:
A.C. contactor is a kind of control apparatus that is used for switching on and off continually at a distance major loop and big volume controlled loop.Contact system can be used drivings such as electromagnet, hydraulic pressure and air pressure.At present, what routine was used is electromagnetic AC contactor, and its electromagnetic mechanism is made up of coil, iron core, armature three parts.Because alternating flux causes magnetic hysteresis and eddy current loss in magnetic conductor, in order to reduce loss and to alleviate the degree of heat, magnetic conductor all uses electrician's silicon steel plate packing to form.The existing problem of this structure shape is:
1, operation is many, complex technical process, and the silicon steel sheet consumption is big, causes cost to increase.
2, for after outage, overcome iron core and cling the phenomenon that does not discharge, structurally, when sound is unshakable in one's determination closed, must leave air gap, removing remanent magnetism, but the existence of air gap more causes entering of dust and noise to increase.
3, in order to reduce suction pulses when the closure unshakable in one's determination, a minute magnetic short circuited ring need be installed on the magnetic pole strength of alternating electromagnet, more increase the temperature rise of coil.
Summary of the invention:
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of need not silicon steel sheet, do not have AC noise under the on-state, no temperature rise, the electronic magnetic formula energy saving ac contactor of little power consumption.
The technical scheme that the utility model technical solution problem is adopted is:
The utility model comprises arc quenching system, contact system, electromagnetic mechanism and mounting seat;
Design feature of the present utility model is in described electromagnetic mechanism, and being equipped with the armature that forms adhesive or disjunction with electromagnetic core is to provide actuating force by the permanent-magnet steel that connects firmly with it; Be provided with and be provided at the electronic module that forms the positive and negative both direction coil current signal of different magnetic poles direction on the electromagnetic core in good time.
The utility model keeps the arc quenching system of existing A.C. contactor, and contact system and mounting seat do not change on version.Just electromagnetic mechanism is set to rely on the control of electronic module, is a kind of new driving mechanism of power with the permanent-magnet steel.Utilize the same sex of magnetic pole to repel each other, there is a natural attraction between the sexes, produces the positive and negative pulse electric current by electronic module, makes the different polarity that produces unshakable in one's determination; State keeps relying on permanent-magnet steel.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model is with permanent-magnet steel and the hold mode that is equipped with unshakable in one's determination, need not silicon steel sheet, there is not AC noise during connection, no temperature rise.
2, the utility model is not subjected to the interference of net voltage, as long as voltage is greater than 85%Ve, all can reliable adhesive, and when net voltage was lower than 70%Ve, no matter voltage reduced fast or slowly reduces, and all can reliably discharge.
3, the utlity model has the time-delay release function, under-voltage time-delay and outage time-delay are had both, and avoid the release movement that moment is under-voltage or decompression is not used, and be reliable and stable.
4, the utility model quick action can be less than 20 milliseconds.
5, to keep electric current low for the utility model, has only the operating current 1-1.5mA of electronic module, and power savings is very remarkable.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model control circuit schematic diagram.
Number in the figure: 1 moving contact, 2 fixed contacts, 3 arc-extinguish chambers, 4 moving contact insulating supports, 5 bases, 6 armature, 7 permanent-magnet steels, 8 pressing plates, 9 fixed heads, 10 bent plates, 11 electronic modules, 12 iron cores, 13 reaction springs, 14 straight pins.
Embodiment:
Referring to Fig. 1, present embodiment comprises arc quenching system, contact system, electromagnetic mechanism and mounting seat.Keep the arc quenching system of existing A.C. contactor, contact system and mounting seat do not change on version, and electromagnetic mechanism is set to rely on the control of electronic module, is a kind of new driving mechanism of power with the permanent-magnet steel.
Shown in Figure 1, the permanent-magnet steel 7 that forms one with armature 6 is set, armature 6 connects firmly by straight pin 14 and moving contact insulating support 4.The armature 6 that moves through of permanent-magnet steel 7 drives moving contact insulating support 4, thereby causes adhesive or disjunction between moving contact 1 and the fixed contact 2, also is contactor adhesive and disconnection.
In order to satisfy the requirement of suction, after permanent-magnet steel 7 and 12 adhesives unshakable in one's determination, do not flicked by reaction spring 13, permanent-magnet steel 7 must have bigger magnetic energy product, high coercive force, temperature stability preferably, therefore selecting NdFeB for use is the permanent magnetism sintered hard magnetic material.Owing to do not contain strategy metal cobalt and nickel, relative price is lower.Select the magnetic permeability height for use for 12 unshakable in one's determination, the soft magnetic material that coercive force is low is generally used the electrical pure iron of the higher trade mark.For satisfy moving unshakable in one's determination 1 with fixed core 2 between open apart from the condition of the excess of stroke, permanent-magnet steel 7 must be clearance between open contacts and excess of stroke sum with the air gap of iron core 12.
Shown in Figure 1, routine setting structurally also comprises arc-extinguish chamber 3, is used to assemble the base 5 of each member, is used for fixing pressing plate 8, fixed head 9 and the bent plate 10 electromagnetic core 12 being installed and being included the electronic module 11 of solenoid.
