Description
Technical field
The invention relates to the electronically controlled device of asynchronous motor of single-phase or three-phase, it comprises the repeater of an electronic cards and control motor energy resource supply at least.Electronic cards and repeater preferably are placed in the capsule.
Background technology
The control device of above-mentioned model both had been suitable for also can be used in the standard environment having in the situation of explosion hazard, but more be applicable in various types of explosive environments, under coal gas or flue dust environment, this type of antiknock anti-combustion motor such as LEROY-SOMER, ELNOR or ATAV (trade mark).This type of motor especially is widely used in and stirs coating or stir the material that other contain volatile component, such as danger classes IIB T4.
For a long time, these control device of electric motor are installed in mainly mechanically basically, as illustrated in patent book EP-A-0.091.360.
Equally, file US-A-6.150.795 has described a control device that is used in particular for threephase asynchronous.This document has been conceived a kind of motor energy resource supply mode, i.e. the parameters of electric power of supplying electric current, and all the frequency with the normal operation of motor is consistent with voltage with voltage for frequency.In order to solve this technical barrier, must there be an electromagnetism repeater, it and converter switch are linked, but the shortcoming of switched mode power converter is clearly: a large amount of electric power that consume when at every turn changing, and when each switch, produce spark.So, when the control running, a transducer is closed, be convenient to first transducer power supply (electric current and control voltage and frequency when this transducer detection service conditions is suitable), the energy resource supply of motor and the conversion of electric power converter when being convenient to the electromagnetism repeater and closing, second detection system is opened subsequently, and it is more more responsive than first detection system, surveys the frequency and the voltage of supplying electric current again.When the condition of supplying electric current was not suitable for, second detection system just can be opened the switch of repeater and electric power converter.More than the electric machinery repeater of Jie Shaoing is compared with electronic-controlled installation, shows many places not fully up to expectations.
In addition, file EP-A-1.079.509 has described the equipment that a kind of electric power is supplied with, it has installed one group of totally three capacitor, by motor energy supplyystem supply capability, these three capacitors produce condensances, and this condensance can reduce the voltage of device remainder and to the indicator light supply capability.Be equipped with one in the middle of the equipment and take detector and send run signal, indicator light or luminous or extinguish to microprocessor.When indicator light lighted, microprocessor was taken detector and is warned, and guaranteed the transistor polarization, became conductor, to electromagnetism repeater conduction, guaranteed the energy resource supply of motor.When mistake appearred in inflow current, indicator light extinguished, and took the situation of detector to microprocessor report indicator light, and microcontroller is opened the electromagnetism repeater, stops the motor energy resource supply.Same, the major defect part of this type of device is attributed to the electromagnetism repeater, because Mechanical Contact is inevitable lossy in the device in the high inflammable and explosive environment.At least three capacitors are also deposited, and all power consumptions of each element require significantly electric current.
Electronic-controlled installation is to answer the trend of product science and technology innovation and occur on market.So multiple electron controls technology no matter be applied to the normal conditions or the electron controls technology of inflammable and explosive environment, all is a dog-eat-dog.In this case; various control technologys are also had nothing in common with each other; the criteria for classifying as; according to electronically controlled character (cable arranged or sequencing); the transducer mode of electromagnetism repeater (mechanical electromagnetism repeater contact or the contact of static repeater thyristor); the parts that start and stop to control; necessary protection and safe mode; to prevent in particularly inflammable and explosive in any environment environment dangerous situation taking place, protection and safe mode must strictly be carried out existing European safely instruction and standard.
According to above standard, we are referring to following example:
The control device of electric motor of some is directly by the motor manufacturer, and especially U.S.'s motor manufacturer recommends, as FRANKLIN or RELIANCE.The Electronic Control of sequencing is installed in the light box of the sealing of plastics, by a cable and outer type, the other end of cable links to each other with another motor wiring post box, and the inside must be equipped with electric power converter, is realized by motor repeater or static repeater in principle.The startup of motor and stop to realize by keyboard operation.Electric power safety device in the inflammable and explosive environment is by the safe mode I of motor anti-explosion cover pattern D and electronic cards itself and its control piece common realization that combine.
This control device has certain shortcoming, and promptly it only is suitable for the motor of appointment, must model coincide, and connects accurately.But in fact also having many is not this " motor and Electronic Control " perfect supporting situation, and this Electronic Control may just can't operate on another kind of motor.
A part of in addition control device of electric motor is recommended by the part manufacturer of electric machinery, such as LEGRAND ATX, and TECHNOR or BARTEC.These control device do not have Electronic Control; but their part all is standardized motor part without exception; as electric separator; the motor protection transducer (can be crossed at electric current and cut off electric current when strong; parts as TELEMECANIQUE), they are contained under the anti-riot cover of D together, and and button-push rod connect; so that when the E safe mode that similar protected mode or standard EN 50019 are mentioned, the control motor moves/stops.When electric power control cabinet and motor connect with supporting cable.
These power control units often appear on electric power manufacture of materials merchant's the product table, be suitable for using under the inflammable and explosive environment, but their shortcoming are: no matter what has identical or different in their each comfortable operations, all be the cost costliness; Internal part is many and volume is big, and the aluminum etui under the safety measure D protective cover or the etui of plastics are too thick and heavy.Therefore, these settling modes are economical inadequately because foundation has contained many parts and attached parts, will inevitably for make these zero, attached parts roll up the investment on the instrument.In addition, any permission authentication only gives a concrete technology and uses, and can not be suitable for one by one other technologies.This class device can put goods on the market very soon at concrete motor product introduction, but can't avoid a weakness: for the mould wash mixer that total cost is descending always, its application will be restricted.
Why in recent years Here it is, and in the mould wash mixer field, FAS and FILLON-PICHON two companies are developing the more economic control device that can more be applicable to explosion-proof engine separately.So two kinds have very much characteristics, well behaved Electronic Control version emerges on market from nineteen ninety-five, is specifically designed to the mould wash mixer of body of a motor car maintenance.
The Electronic Control version of FAS company comprises an integrated electronic card, the unified above power converter that the motor repeater type has been installed.This electronic cards both can be placed in the plastic casing of standard, also can be placed in the aluminium box of anti-explosion cover D, was specifically designed to inflammable and explosive place, conformance with standard EN50018.The startup of motor and stop to realize by the touch button of soft keyboard.The parts of an ampere meter type guarantee the safety of motor.Another feasible mode is, electronic-controlled installation integral body is installed in the binding post box, promotes control with button-push rod, enables the D protected mode under explosive environments.The version of FILLON-PICHON company is put into the transducer of the static repeater of a sequencing electronic cards and a CELDUC exactly at least in a capsule, the energy resource supply of control motor.The startup of motor and stop to realize by the touch button of soft keyboard.The cardinal principle rule application of European standard EN50014 is used in combination with system's inherently safe pattern " I " (European standard EN50020) when especially " M " (European standard EN50028) operated in compression such as Polyurethane or epoxides bottling at the explosive environments guard system.
In these two kinds of versions, electronic cards comprises a transformer at least, is welded on the electronic circuit, and circuit is connected on the power supply by the phase line of motor electric power system.The function of this transformer is to reduce voltage, therefrom extracts necessary voltage and offers an adjuster, and adjuster recovers voltage again, uses for control device specially in the mode (several volts) of burning voltage.A fuse is installed on the electric current source of this transformer, and the protection transformer prevents that electric current is strong excessively, or the instantaneous heavy current that causes when unstable of electric current.
These different control device have various shortcomings.
In fact, transformer can not both effectively stop and weaken the highest voltage that enters, and the danger that does not cause heating is the simultaneous adaptation voltage of various numerical value on a large scale again.
To first point, a transformer even no-load operation, is also wanted consumed energy and is generated heat.Overtension or when surpassing 250 volts more can increase the weight of the transformer heating, thereby unavoidably cause parts damages still more.
To second point, the manufacturing technology of transformer has comprised and a kind of dependence of transformation steady state value " Rt ", becomes corresponding relation with coil number, i.e. proportionate relationship between first coil number N1 and second the coil number N2:
U2/U1＝I1/I2＝N2/N1＝Rt
Wherein:
U1 and L1 represent the voltage and current of first coil respectively
U2 and L2 represent the voltage and current of second coil respectively
Under these conditions, research method compromise, feasible requires to enlarge the ability of transformer, according to EN50028 standard relevant regulations, as bottling " M " pattern, adds a hot fuse with the control temperature.For reaching this purpose, the realization that production technology is becomed privileged requires to raise the cost.
In addition, the envelop of function of the transformer that existing performance is best is still very limited, is difficult to satisfy the requirement of present countries in the world network system.Therefore must possess at least two kinds of transformers, suitable and installation suitable transformer at the power system network of country.In addition, according to the size of voltage, must be reduced to a suitable value to voltage, the assurance adjuster can use all the time and provide stabling current to electronic-controlled installation.
In addition, we must have a resistance transformer on the one hand on electron plate, and electron plate itself is placed on the alclad, and in the static repeater components of the inner independent installation code of capsule, etui is positioned on and is used on the same block of aluminium sheet dispelling the heat on the other hand.But such integral installation relative volume is bigger.Should integral body must be wrapped by protective materials fully simultaneously, resin for example so that and explosive environments energising SI semi-insulation down, strict needs with reference to " M " mode construction.Wrappage must have the thickness of 3mm on the highest parts top, also needs so around other electric components.Such insulating requirements must cause consuming in a large number resin material, causes the cost superelevation when the production control device.
Also have, when many independently electric subassemblies by binding post, weld or the shunt of lug plate, pad or the increase of inlaying when being installed together, abundant preparation must be arranged, and installation procedure is very complicated, be difficult to grasp.Although in each stage of industrial production many Quality Control Procedures are arranged, careful, the shelf-life of product is difficult to guarantee.In fact, long-distance transport process or the abnormal operation under extreme environment all can cause damage of product.
At last, the film soft keyboard in the control device damages after also may using a period of time, stops up such as touch button under resin excessive expansion or the excessive temperature all to cause the fracture of circuit joint cover.So the system requirements quality of materials is really up to the mark, and the strictness of industrial production control dynamics, preventing nonstandard operation or out of trim, high quality control causes the also corresponding rise of cost certainly.In addition, when electric component (promptly is not installed in the place of explosion hazard) such as supervisory keyboard outside being installed on sealing area, must the ZENER protecting screen be installed in the downstream of transformer, be used to limit the energy of the electric component of seal area outside, avoid producing spark, spark is caused by fuse usually.
Simultaneously, the security set of electronic cards is had an effect by the member of fuse and so on, prevents the startup of motor when electric current misconnection or motor service conditions are inabundant as yet.Members such as fuse all are placed in resin inside, and in a single day they disconnect, and control device can't move, and is at a standstill, because they can't be equipped again.
Summary of the invention
The objective of the invention is to recommend a kind of novel control device, attempt the volume of restraint device integral body, the hidden danger that elimination damages in the harshest condition lower member (as transformer or flexible film keyboard in some shortcomings that constituted now control device), carry out effective electric power safety control, avoid in the past some parts in using damage and irreversibility, for example fuse of insulating material or piezo-resistance.

Description of drawings
In the present invention's example hereinafter detailed description is arranged, and can be with reference to the diagrammatic sketch that invests behind the literary composition:
Fig. 1 represents the control device plane graph, the position of display member and member;
Fig. 2 represents the three-dimensional sectional drawing of control device.
Embodiment
Device of the present invention is specifically designed to the Electronic Control of the single-phase or threephase asynchronous of operation under the inflammable and explosive environment.
This device generally places box 1, and general is material with insulation, anti-static plastic, generally includes an electronic cards 2 and a static repeater 3, the energy resource supply of control motor and open or close according to the characteristics conversion of main power source.
According to characteristics of the present invention, electronic cards 2 comprises a condensance 4, and some thin slice change over switches 5, switch are by magnetite 6, and button-push rod 12 and microcontroller 7 are controlled.Control device is powered by the motor supply network.It and phase line link, and phase line links with main power source again.The voltage of this network can be between the 70-260 volt (single-phase), and might receive 400 volts (three-phases), and frequency is the 50-60 hertz.
Can power to control device in order to make the motor electric power system, must reduce voltage, obtain a lasting weak magnitude of voltage to electronic cards 2 power supplies, different with the technology of using transformer reduction voltage is, the way that keeps is prepared a condensance 4, and it is made up of one group two capacitors (being generally plastics).Such as when single-phase motor was powered, this condensance comprised that one group of two condenser capacitance is 1uF, model X2275VAC, and big or small 23*20*9mm does not generate heat when guaranteeing work, even if under 260 high pressure.In fact, if when using Control current especially a little less than, less than 10mA, can consider to use small-sized capacitor, minimize the use resin as far as possible.These capacitors must reach parts can bear 2/3 o'clock of ceiling voltage also can operate as normal, the voltage limit of heating is down guaranteed at full capacity in the requirement of electric power safety work under the inflammable and explosive environment of the regulation that conforms to current standards.
When electric current was strengthened, the capacitance of capacitor may be double, and volume can expand to some extent simultaneously.Volume may be adjusted to optimum state when electric current was the most weak.With this reasoning, when electric current strengthens, must increase the quantity of capacitor.
This condensance is connected on the single-phase motor with phase line, reduces the intensity of service voltage, makes to be lower than 25 volts.Between the condensance 4 and the neutral line, insert a diode bridge, voltage is defined in 5 volts.Other capacitor can be placed on the circuit downstream of this diode bridge, guarantees that electric current is unobstructed, makes remaining alternating voltage short circuit.So its purpose is to obtain a voltage that is stabilized in several volts by these multiple parts, be microcontroller 7 power supplies of PIC 16C620 specially to model.
The microcontroller 7 that this electronic cards 2 has, the parameters of electric power of analysis main power source is such as frequency and voltage, compatibility when guaranteeing them with the motor normal operation, so that control static repeater 3, this repeater places on the motor power supply system network, especially on the phase line of motor.The effect of static repeater 3 is according to the characteristics decision path of main power source supply current or opens circuit.Microcontroller 7 also has the effect of control motor operating time in some cases.
The effect of microcontroller 7 mainly is to monitor the current strength that enters electronic cards.In fact, it is controlled service voltage all the time, does not start static repeater or in the electric power safety pattern of device upstream as far as possible.
The purpose that microcontroller monitors is to adjust the threshold parameter that voltage enters, and guarantees that motor is within the margin of safety (to search mistake, shuffling information, relay time-delay etc.), and its function also has some other intelligent embodiment.
For this reason, we use is monitoring and the analysis that the microcontroller model of " analogy or comparable " is used for call parameter.
The reduction of service voltage realizes by a condensance,
The function of frequency has following relation:
Lu=Ur/Zc and Zc=1/ (C*2 π f)
So Ur=Lu/ (C*2 π f)
Therefore, voltage is different because of the difference of frequency.Can determine voltage network (indirectly by the voltage after reducing) by monitoring frequency, control minimum voltage and maximum can enter voltage, and when going wrong, microcontroller can be issued an order, and stops the motor running.
The startup of device and stopping by flexible thin sheet transducer 5 control, and transducer is by button-push rod 12 and magnetite 6 controls.Button-push rod 12 can be replaced by the device of other identical functions, but preferably all is manual.The form of button-push rod still is the choosing of going up in the present feasible method.In order to satisfy the security needs in the explosive environments, electronic cards 2 and static repeater 3 all will be deposited by close, promptly are immersed in the insulating material 8, such as resin.Condensance 4, static repeater 3 and electronic cards volume are little, have therefore saved the quantity of the insulating material that need use when making.
The definition of bottling sealing: use epoxy resin or polyamine resin composite material to wrap up in or the mode of tinning has been sealed one or several electric device by being coated with.What is called is coated with and wraps up in is exactly to cover one deck insulant on one or several electric device.Elder generation's handle assembly is placed in the mould, goes up insulation composite then inward, waits compound to do later on and takes out.So-called tinning is that being coated with of another kind of mode wrapped up in, and promptly device need not to take out, and is sealed in the mould all the time.The bottling here sealing refers generally to the latter, promptly toppled over insulating material after, mould is in the same place with device all the time, it and be coated with the difference of wrapping up in and just be whether to wait insulant to dry handle assembly taking-up afterwards.Like this, electronic cards and static repeater height have only 8mm, and resin thickness has 26mm.In this structure, device has two thin slice transducers 5 at least, and frame is on mounting 11 respectively, and especially near insulant 8 surfaces, so that control, remote operation does not cause by magnetite 6 to electrically contact.Except that this form, the another one version is promptly without insulating material, and integral body is packed in the D protective cover.
Technology is good, guarantee that we have had multiple variant version under the situation of electronic cards, can be with bottled seal pattern M, or be used in combination pattern I own or anti-explosion cover pattern D.We can imagine that the transducer itself outside the electronic installation sealing area can be by manual or automatic switch control.
Static repeater 3 comprises the thyristor of a 3A at least, had better two statures be installed by pin, pin correctly, is welded on the plate of conductive material 10, such as aluminium sheet, is used for heat radiation, guarantees the heat exchange in narrow space, and it is overheated to prevent.So plate 10 takes the shape of the letter U, thickness 1.5mm is to provide maximum area of dissipation.
Integral body is placed in the etui, comprising:
-bottom surface 1A comprises collets 8, inner submergence electronic cards 2, static repeater 3 and heating panel;
-lid 1B is fixed on the 1A of bottom surface with ratchet mechanism, need not use instrument.
One or several thyristor is installed on plate of conductive material 10 can at first be put into cartridge bottom to this plate, weld electronic cards and other above-mentioned parts of mentioning then onboard.In case integral installation finishes, just in box, topple over insulating material, in order to sealing.
According to EN 50028 standards that preamble is mentioned, after power components was sealed, these materials all are coated with had wrapped up in one deck insulant.When if the thickness of protective cover has 1mm at least, do not stipulate the minimum thickness in the intermediate layer between protective cover and the parts (or conductor).Therefore, the optimal volume of resin has increased 1mm at least again because of the overcoat thickness of box.So heating panel can be placed on cartridge bottom, directly contact.
For the startup that guarantees this device with stop, mentioning as above-mentioned, should join some magnetites 6 for thin slice transducer 5.Each all is positioned on these magnetites 6 on button-push rod 12 (spring 14 is housed), and magnetite 6 is installed among the lid 1B.One of them button-push rod is used for starting drive, and another then is responsible for shutdown.These thin slice transducers are that the work that is in particular microcontroller 7 is prepared.
As mentioned above, electronic cards is directly by the energy resource supply network power supply of motor.Therefore integral installation is on the single-phase motor phase line.So the motor supply power voltage is just powered to control device through after the step-down of condensance.This condensance can be accepted the voltage of various scopes, particularly the voltage of 70-260 volt, frequency 50-60 hertz.In case voltage drops to the 8-25 volt, the various parameters of electric power and the frequency of back voltage falls in microcontroller 7 analysis, and calculates the primary voltage value, to prevent starting static repeater when this primary voltage value above can bear voltage range the time, prevents that motor is impaired.Static repeater also is installed on the motor phase line, the strict regulation of carrying out in the electric power safety standard about electric phase curve.
In order to guarantee the installation of single unit system, box bottom 1A leaves little lattice the mains power cable line of turnover is installed, and little lattice and collets 8 are separated by dividing plate 13.Dividing plate has one group of wire casing at contiguous top edge, makes things convenient for attached cable.The axle envelope also is housed in the capsule, and cable can link by axle envelope and main power source, powers to motor.If meticulousr, can consider tie cable on the binding post outside bottle envelope zone but still in protective cover, guarantee that electric box has an independent cable.Under explosive environments, this binding post should protect according to intensified safety pattern E.This pattern especially requires the strict sealing of protective cover, and the protection index reaches IP54.In order to reach this requirement, capsule week makes a circle groove, and the junction can effectively guarantee sealing, reaches required standard.
At last, for guaranteeing that electronic cards 2 contains a double-colored diode transistor to the lasting supervision of device operation, outstanding from collets 8.The lid 1B that this diode transistor is put luminous guide 16 and box 1 connects, and from box 1 outside, the light of diode transistor as seen.All operation failures can be by visible like this, and durable.Simultaneously, when electric current did not meet motor operation normalized current, static repeater will stop electric current to pass through.
For the ease of the installation of box 1 on mounting, bottom 1A can connect several " pawl dress things " 9 are convenient to the mounting of holding.
Very simple during this control device operation.In case power supply connects upward and on the other hand with motor on the one hand and connects with main power source, wants to start this device, only needs to open the button-push rod of corresponding intrument startup, that's all.Be tied with magnetite on this button-push rod, attract thin slice transducer 5, as lamp REED even connected.The bridge formation in condensance downstream guarantees to provide 5 volts lasting light current to press to microcontroller 7, just can analyze the parameters of electric power of main power source, when the voltage of being supplied with and motor normally moved compatibility, it was that electric current is let pass that microcontroller 7 is just ordered static repeater 3, straight-through motor.At this moment motor just can continuous service a period of time, and this time period generally has been set in advance in the microcontroller 7.During to setting-up time, motor stops automatically.In case of emergency, can operate another button-push rod and stop motor.
For threephase motor, every phase line has a static repeater 3.
