Abstract
This invention discloses a switching equipment comprising especially relays and/or switch contactors with a magnetic system, the armature and the yoke, a winding and a winding support as well as a control and/or driving system, where the real value of the switch-drive parameters is determined using sensors. The control and/or driving system and the sensors are located inside the winding support and/or thereon.
Description
The present invention relates to a kind of switching device, especially the relay and/or the contactor that have magnetic system, it comprises armature and yoke, and coil that has a bobbin and one regulate and/or control device, wherein utilize transducer that the actual value that drives special-purpose switch parameter is detected.
The switching device that has magnetic system, for example contactor can be used in driving and the automation engineering, and they can be used for ensureing the safety of electrical appliance and controlling them in conjunction with other element.
Considering under different service conditionss and the special instrument characteristic situation, for these switching devices are mated with its break-make task best, existing people develops the operation principle of gate-controlled switch drive unit, and it has reduced because the driving voltage difference diversity of necessary coil so far.Such operation principle not only can be used for alternating current and also can be used under the direct current situation, and it is by reducing the scaling loss that contact bounce has reduced the contact, and then has improved the useful life of contact.Meanwhile, the power loss of exciting circuit also reduced in the maintenance stage.
Disclose a kind of control circuit by EP 0,376 493 A1, it has reduced the contact bounce phenomenon in electromagnetically operated valve.At first motion stage, for being arranged, high suction moves speed, allow high electric current, this high electric current is dropped to a lower value before electromagnetically operated valve does not also cut out.In DE-OS 3047488A1 except describing a coil current control device, an induction adjusting device has also been described, it has an aural sound suddenly (Hallsonde) that is arranged in the yoke, it allows the coil current of a raising equally when motion stage just begins, this electric current back is at the fixed time dropped on the certain value, and this current value can produce just and keep being inhaled the necessary power of moving armature.DE-OS 4430867 A1 have described the adjusting control that switching devices drives, and it makes contact speed keep best and has limited armature core stroke speed in whole use, simultaneously to interference parameter, has also carried out necessary consideration as scaling loss and tolerance.
Though be devoted to address the above problem always by the known wiring that is used for the switchgear driving mechanism, but do not set about inquiring into the problem of customer-side, for example be convenient to maintenance, EMV fail safe and when daily use switchgear, be convenient to operation or the like.
The objective of the invention is to create a kind of wiring that is used for the switchgear driving mechanism, it has the advantage described in this paper foreword concurrently and be convenient to maintenance in everyday practice, is convenient to operation and also has the EMV fail safe simultaneously.
The object of the present invention is achieved like this, a kind of switchgear promptly is provided, especially the relay and/or the contactor that have a magnetic system, it comprises an armature, a yoke, a bobbin and a control electronic unit that has a coil, it has the transducer that is used to survey the actual value that drives special-purpose switch parameter, a forced ventilation groove crack is wherein arranged between yoke and armature, in this switchgear, be provided with a communication electronic unit that is electrically connected with the control electronic unit, for surveying the actual value of the magnetic flux that is produced by coil, at least one transducer is bearing in the forced ventilation groove crack of bobbin.
That is, the present invention is arranged on adjusting and/or control device and transducer in the bobbin or is disposed thereon.Can be understood as the control electronic unit and/or the communicating circuit of switchgear in adjusting and/or the description of control device below this specification.Because coil holder structure is compact and it also includes all the sensors, adjusting and/or control device and connector, thereby can replace traditional bobbin easily.The data/address bus of going to master console connects by the answer of switchgear has simplified process monitoring (report " connection-disconnection ", control voltage is resident, reports the state of another equipment, the remaining life of main contact).Can set by the parameter of master console switching devices in addition.
Other favourable improvement design of the present invention by dependent claims as can be known.
By an accompanying drawing embodiments of the invention are described in further detail below.
This accompanying drawing is the simple exploded view that has the magnetic system of a U sections core.It has yoke 1, armature 2 and bobbin 3.Wherein, yoke 1 and armature 2 have same structure with present existing yoke or armature.Bobbin 3 is by a coil 4, a magnetic field sensor 5, the communication electronic unit 10 that has a busbar joint 12 above contactor control electronic unit 10 and one are inserted in, the connector of control voltage 13, be used to show the auxiliary switch 14 of contactless contactor position, temperature sensor 15 in the electronic unit 10,11, coil 4 and are used for the digital input port 16 of the report of another switchgear and form.This magnetic field sensor 5 is positioned on the lath 6 of through hole 9 of a cross-over connection bobbin 3, and this through hole 9 is used for the supporting leg 8 that yoke 1 has forced ventilation groove 7.
By this bus system 12, can carry out the remaining life and the temperature of relevant electronic unit and coil by a master console, the status enquiry of the control voltage and the position of the switch.In addition, can carry out parameter setting to contactor, for example can change the lag time constant and the threshold value of the adjusting control loop of contactor control electronic unit by master console.These bobbin 3 modular cramped constructions are with the advantage and the compact conformation of controlled contactor driving mechanism, and EMV fail safe and the advantage of being convenient to operate all are unified.
For the magnetic system of other structure, for example E sections core also can adopt the bobbin with corresponding configuration, and run through jack this moment 3.
