The specific embodiment
Contact by relay or contactor control is represented with the symbol of this relay or contactless switch and the sequence number behind the slash in the accompanying drawings.
The three-dimensional project organization of circuit of the present invention is a part of carrying out submodule part SM.It is divided into assembly SB and monitoring component UB; Two assemblies interconnect.Carrying out submodule part SM links together switch machine WA and power supply SV with the computer system RS that controls and monitor.Power by a source of AC net that has ground wire; Switch machine WA for example is a three phase current point machine and is powered by four lines.The contact of for example not shown execution relay and the contact of switch location relay are used for the connection of assembly SB power circuit.These relays are parts of relay control system RA, and this control system obtains its control command from computer access K1 and the K2 of the computer system RS that controls and monitor, and a direct supply GV is for carrying out the power supply of relay and switch location relay; Rod changer assembly GV
*Be used to provide connected to chassis to monitor vdc.This supervision vdc is used to produce the answer signal of relevant point machine position in monitor assemblies UB.This status signal is converted into monitor signal in signal control part MA, this monitor signal is fed to two computer access of computer system RS and calculates at this place.For the power supply potential with monitor assemblies output inserts in the actuator assembly and for the supervision current potential that will represent certain switch machine position is recycled to monitoring component by actuator assembly, adopt being connected between moving bridge contact B realization actuator assembly SB and monitor assemblies UB.As described below, can set up the relation that needs between actuator assembly and monitor assemblies by this moving bridge contact, this relation is by different point machines and different switch machine circuit decisions.
Fig. 2 is the specific design of circuit of the present invention when being used for the three phase current switch machine WA of four lines operation; Carry out voltage source and have grounding jumper.Each service direction of switch machine by the computer system of controlling with the binary channel mode by being used for a certain service direction or another service direction directional relay R or L be switched on or switched off predetermined.Set in described embodiment, track switch is positioned at positive position, and wherein the switch member of circuit is positioned at the switch position shown in Figure 2.Have two signal head M1 and M2 that only schematically illustrate in the drawings, be used to monitor switch location.This signal head input current potential (supervision current potential) is abundant will be when high at one of two mouths output signal current potential; For example in DE3516612C2, this signal head that cooperates with the supervision of optical signal has been done record.The signal potential that is picked out by one of two signal heads or another mouth inserts signal message MK1, MK2 in the position that conforms to mutually and is sent on two computer access of the computer system of calculating.Wherein the configuration of being taked should make two signal head M1, M2 under the normal working of switch machine terminal all the time at mouth output signal current potential inequality and insert two computer access, wherein inserting one or another mouth depends on, track switch being is positioned at positive position, still negative position.Only when irregular, promptly when switch machine squeezes trouble or other fault occurs, for example when insert that point machine regulates that the single contact of current return takes be wrong connection location the time, two signal heads will be at identical signal potential of the mouth output polarity that meets mutually or output signal current potential neither, and the computer system that this situation will be carried out calculating is used for fault recognition (Fig. 8).
Have two independent direct voltage source U1, U2 is as the power supply of signal head.Two other direct voltage source U3, U4 are used for signal head M1, and the control of M2 provides the supervision current potential.Monitor that current potential is added on the signal head by the switch machine transit node.Two direct voltage source U3, the positive pole of U4 and negative pole are respectively by a dedicated line ground connection.The common ground line constitutes the reference potential of two signal heads; This reference potential is added on the signal head by dedicated line.Because direct voltage source U3, U4 and signal head M1, M2 adopt dedicated line to be connected to reference potential, so can identify the unexpected line interruption to reference potential reliably.Direct voltage source U3, U4 and signal head M1, the common reference potential of M2 is identical with the reference potential at current and power supply place.Monitor that according to its input the signal potential of current potential output has only in normal operation, is just calculated by computing machine when switch machine is disconnected by signal head.If when the switch machine motor disconnects, because fault, for example because the contact clinkering, when needing to connect one or more and regulating line, it is overlapping and have at least a signal head all not have signal potential output at its each mouth with the supervision current potential of being gone into by the switch machine side joint at this moment to carry out voltage.The computer-made decision that this situation will be carried out calculating is fault (ground connection indicator signal) and this is made predetermined reaction.
The positive potential of the monitor voltage that is provided by direct voltage source U3 at described switch machine terminal location does not have a connected to chassis signal input part through what machine winding W3, switch machine transit node AK4 and coil W1 were added in signal head M1, and the negative potential of direct voltage source U4 is added in signal head M2 by switch machine transit node AK1 and coil W2 does not have the connected to chassis signal input part.Therefore signal head M1 at its positive output end output signal current potential and signal head M2 at its mouth output signal current potential.The signal potential of two signal heads is respectively at two signal message MK1,0 of MK2.When another switch machine terminal location 1 of the signal potential Seize ACK message message of signal head.The computer system of calculating is judged each position of the point machine of its supervision according to the signal potential of binary channel input.
Set below, track switch will be by changing-over to the another location.By this changing-over of computer system starting.Handle the control corresponding instruction of directional relay R and L under it mutually insusceptibly for these two computer access.Wherein directional relay L is disconnected by the instruction K1K1 from computer access K1 by the directional relay R that connects from the instruction K1K2 (Fig. 1) of computer access K2 and be in on-state always.Its break-make position of conversion simultaneously, the contact of this relay, wherein contact R/1 and L/1 disconnect and R/2, R/3 and L/2, L/3 closure.These contacts are at bistable state position relay R1, R2, and L1 is in the connection current return of L2.The bistable state position relay is used for by its contact R 1/1 in switch machine motor power loop, L1/1, R2/1, given certain service direction of L2/1; They are regulated and control by temporary transient access power line voltage.Each position relay only has a unique switch contact and also has only unique one to adjust the angle.The position relay changing-over this means, in order to be changed direction of current in the position relay to certain another settling position.Here pass through contact R/2, L/3 and R/3, L/3 and R/1, R/2 realize this step.Per two are serially connected respectively in four position relaies, its setting is determined by following manner: according to the connection of directional relay R or directional relay L, otherwise perhaps two position relay R1 and R2 be connected on active position and two position relay L1 and L2 be connected on home position or.Non-loaded connection is carried out in the contact of position relay.Exactly, feeder line to the connection of switch machine is that contact H11/1, H21/1, H12/1 and H22/1 by auxiliary contactor H11 to H22 realizes.These auxiliary contactors are connected by command adapted thereto K2K1 and the K2K2 from or another computer access, per two series connection (Fig. 2) respectively of wherein said auxiliary contactor.It is communicated with respectively, and the conversion of direction of passage and position relay realizes.For these two computer access temporarily will be connected with switch S 1, the S2 that auxiliary contactor is serially connected; Then switch is kept by the running current monitoring device LU that also will be illustrated below.Wherein carry out feed by two computer access from start to finish, thereby can cancel the connection of auxiliary contactor at any time.The setting of the contact of auxiliary contactor in switch machine motor feeding circuit should make to be had only when the auxiliary contactor of being controlled by different computer access is closed, promptly when two computer access are communicated with, just realizes feeding circuit.
Fig. 3 to Fig. 7 is to the connection of the point machine after arriving new terminal location, and commutation operation and the process that monitors illustrate.
The state that Fig. 3 illustrates implementation when starting point machine when beginning; This moment, contact A K1 to AK4 did not also have changing-over.Realize first current return and realize second current return through contact H11/1, L1/1, coil W2, switch machine transit node AK1 and contact H22/1 through contact H21/1, coil W3, switch machine transit node AK4, coil W1, contact L2/1 and contact H12/1.Positive and the negative supervision current potential that adds to signal head M1 and M2 is overlapping by voltage.Therefore computer system is not calculated when the point machine commutation moves the signal potential of signal head M1, M2.For example computer system judges according to the monitor signal of described running current monitoring device LU whether needs calculate signal potential.
The feeding circuit that starts the back run duration at switch machine shown in Figure 4.Switch machine transit node AK1 and AK3 have carried out changing-over; Switch machine moves in star circuit this moment.Form first current return and form second current return through H11/1, L1/1, coil W2, AK3, coil W3 and H21/1 through H12/1, L2/1, coil W1, switch machine transit node AK4, coil W3 and H21/1.Signal potential to signal head M1, M2 will not calculate from start to finish.
Fig. 5 illustrates switch machine and arrives negative terminal location switch machine loop constantly.This moment, switch machine transit node AK2 and AK4 carried out changing-over.The running current monitoring device has been cancelled the control voltage of switch S 1, S2 and has been disconnected auxiliary contactor thereupon.Still be in closure state owing to be communicated with the contact, monitor the stack of current potential and feed alternating-current voltage/AC voltage, so to monitoring that current potential does not still calculate.
In Fig. 6, after the auxiliary contactor disconnection that therefore switch S 1, S2 disconnection also cause, the power supply of switch machine has been interrupted in its contact.At this moment can and by computer system signal potential be calculated again.The positive potential of direct voltage source U3 is added on the signal head M2 through W3, AK3 and W2, and the negative potential of direct voltage source U4 is added on the signal head M1 through AK2 and W1.Computer system identifies the existing condition of switch machine according to the signal potential that extracts on the signal head mouth.
For comprehensively understanding, the terminal location that will in Fig. 6, set switch machine below.The generation of monitor signal is illustrated when squeezing trouble.Contact A K2 by changing-over when squeezing trouble interrupts so far being connected between direct voltage source U4 negative pole and signal head M1.Switch machine transit node AK4 by same changing-over is added in signal head M1 with the positive potential of direct voltage source U3 and goes up and also be added on the signal head M2 by switch machine transit node AK3 simultaneously.The computer system of calculating judges that according to the identical output signal of two signals fault occurred also reacts this fault thereupon in the corresponding way.
Switch machine from negative position to positive position the commutation operation and also can produce corresponding process during crowded trouble in positive position.
Fig. 8 is illustrated in the signal head M1 that each point machine position produces, the signal potential of M2 with truth-table format.
To describe the 26S Proteasome Structure and Function of running current monitoring device LU below in detail.
Running current monitoring device LU (Fig. 2) mainly is made of a voltage transformer that has two primary winding T1.1 and T1.2 and output primary T2.The number of turn of two primary windings is identical; But their connection should make the supply current in their internal flows produce mutual oppositely directed magnetic field.In the whole process of point machine operation, the supply current of two primary windings differs and is always 120 °.Thereby on the output primary of running current monitoring device, just produce a voltage, and this voltage is enough to remain on the switch S 1 that point machine commutates when moving and auxiliary contactor is serially connected, and S2 is in closure state.But the primary winding that moves current monitor when arriving new terminal location is by the mutual reverse direction flow mistake of identical supply current, thereby the voltage on the transformer secondary output coil drops to null value.The running current monitoring device then disconnects and interrupts by its contact indirectly thereupon the power supply of point machine with switch S in the feeding circuit of auxiliary contactor 1 and S2.
At running current monitoring device timely cut-off switch S1 for some reason, during the situation of S2, two computer access will be paid switching function independent the time, and this function will disconnect the power line voltage of auxiliary contactor when breaking down.Time monitoring will begin when starting control process and finish when commutating the maximum switch machine time of run of operating provisions for switch machine arriving.
For the great point machine of power being carried out break-make control, can at first start other contactless switch by auxiliary contactor, the contact of other contactless switch is connected the feeding circuit of point machine more then.
In the embodiment of the three phase current motor of four lines operation, one have six bridging contact B1 to B6 at one of Fig. 2, realize carrying out cooperating between the circuit part of circuit part that electric currents are communicated with and supervision by these bridging contacts.The laying of bridging contact should make the relation between foregoing execution and function for monitoring be achieved.For the point machine of controlling by other control circuit, other bridging contact to be set for the relation that guarantees to be scheduled to.Below in conjunction with another embodiment this is illustrated, what wherein relate to is that three phase electric machine drives, and this motor only has four bridging contacts by six feeder lines altogether, and promptly B3 to B6 substitutes six contacts; Save B1 and B2, this is can not reuse because heart yearn quantity is too much because of the feeder line to point machine.
Fig. 9 is illustrated in the point machine of terminal location, and what corresponding herein switch machine was got is positive position.Feeding circuit is disconnected and constitutes following monitoring circuit: positive potential, coil W1 and the W3, switch machine transit node AK8, the M1 that detect voltage source U3; Detect negative potential, switch machine transit node AK6, the M2 of voltage source U4.The computer system of calculating identifies the existing condition of point machine according to the current potential of input.
The state of feeding circuit when point machine commutation operation shown in Figure 10 begins.Be communicated with among back formation Figure 10 with the feeding circuit shown in the thick line in position relay changing-over and auxiliary contactor.On coil W1 and W3 and W2 and W3, be added with the phase voltage of interlinkage respectively; The switch machine entry into service.Wherein switch machine transit node AK5 and AK6 (not shown) are alternately prepared for switch machine is communicated to the another location again.Monitor that current potential is performed the voltage stack, computer system is ignored the current potential of two signal head outputs.
In case switch machine arrives new terminal location, switch machine transit node AK7 and AK8 among Figure 11 finish changing-over.At this moment the execution current return of three machine winding is disconnected.So far the running current monitoring device (Fig. 2) that constantly activates by the feeding current that on circuit L2, flows with the switch S in the feeding circuit of auxiliary contactor H11 to H22 1, S2 disconnect thereupon by in the feeding circuit of machine winding with the disconnection of the disconnection realization switch machine of the contact of this contactless switch and when having only two computer access when computer system to impel to reclose switch machine, switch machine just can turn round again again.Along with the disconnection of carrying out voltage, computer system is calculated the output potential of two signal head M1, M2 again.The positive potential of direct voltage source U3 is added on the signal head M2 and the negative potential of direct voltage source U4 is added on the signal head M1.Two signal heads flow to computer system with corresponding signal in the binary channel mode, and computer system identifies switch machine thus and normally reaches negative terminal location.
Figure 12 is illustrated in the process that switch machine squeezes the standby current loop when branching off, and wherein sets, and point machine is originally in positive position.Contact A K5 and AK6 changing-over when point machine squeezes trouble.The positive pole of direct supply U3 is added in the signal input part of signal head M2 by coil W2 and W1 and switch machine transit node AK5 and is added in the signal input part of signal head M1 by coil W2 and W3 and switch machine transit node AK8.Be added on two computer access according to positive signal potential, the computer system judgement of calculating fault occurred and has exported a corresponding breakdown signal.
When the track switch switch machine squeezed trouble by negative position changing-over to positive position or in negative position, the process of being carried out was with identical according to the process of Fig. 8 to 11 explanation, and the truth table of Fig. 8 also is applicable to the point machine of above-mentioned six lines operation.
Figure 13 is the application of circuit of the present invention in single-phase switch machine motor M.Set track switch by electric machine control among the figure in positive position.Wherein the positive potential of the direct voltage source U3 negative potential that is added in the signal input part of signal head M1 and direct voltage source U4 by switch machine transit node AK1 is added in the signal input part of signal head M2 by switch machine transit node AK4.
When wanting changing-over track switch, computer system at first makes directional relay R disconnect and directional relay L connects, and wherein the directional relay contact is in bistable state position relay R1, R2, L1, the changing-over in the feeding circuit of L2.Through of short duration access power line voltage, position relay L1 and L2 arrive its active position and position relay R1 and R2 and arrive its home position.Contact R 1/1 no-load of position relay R1 disconnects, and the contact L1/1 no-load closure of position relay L1; The service direction of two contact decision switch machine motors when inserting execution voltage.Bistable state position relay even after disconnecting its power line voltage, still keep its certain mode of operation.Then computer system is communicated with auxiliary contactor H11 to H22 after to the position relay changing-over, and wherein this for example is communicated with in short time by an auxiliary capacitor and pair regulates with series connected switch S 1 of auxiliary contactor and S2.Along with by contactor control connecting terminal H11/1 and the closure of H22/1 then have the electric current of adjusting to flow, running current monitoring device LU will continue to switch S 1 and S2 feed.At this moment point machine commutation operation, wherein at first switch machine transit node AK2 and AK4 changing-over.Two signal head M1 and M2 be at this moment at its positive output end output potential, but be coupled to monitoring circuit owing to carry out voltage, and computer system is not calculated this current potential.Along with arriving new terminal location, switch machine transit node AK1 and AK3 also carry out changing-over.At this moment the negative potential of the direct voltage source U4 positive potential that is added to the signal input part of signal head M1 and direct voltage source U3 by AK3 is added in the signal input part of signal head M2 by AK2.Also carry out changing-over along with arriving new terminal location switch machine transit node AK11 and AK12, wherein switch machine transit node AK12 interrupts the feeding current loop of machine winding M and thereupon also with the failure of current of running current monitoring device.This running current monitoring device disconnects auxiliary contactor by switch S 1 and S2 and also whether is communicated with motor again according to the participation decision of computer system thereupon.Switch machine transit node AK11 closure is for changing-over after the switch machine is prepared to other direction.
The structure of the submodule part of forming by actuator assembly and monitor assemblies, as noted above, always identical, irrelevant with the point machine motor with several line controls.Drawn the input and output side of monitor assemblies and actuator assembly has realized by electric bridge this input and output side being connected with lead mutually in case of necessity setting up two cooperations that inter-module is required thus by execution submodule part.The connection of this moment should make and monitor that current potential is added on the signal head through the switch machine transit node of electric machine control, thereby makes signal head determine the signal voltage that output is necessary at the detected switch location of need.So circuit of the present invention is applicable to various types of general-duty point machines, with to utilize several feeder circuits that switch machine is carried out energy power supply irrelevant.
Adopt the contact of four auxiliary contactors to carry out the connected sum disconnection of switch machine motor feeding circuit.When one of them contact was in open position for a long time, for example because an auxiliary contactor no longer can be communicated with, at this moment switch machine no longer may arrive its new terminal location usually in the commutation time of run that allows.The computer system of calculating, is judged fault to have occurred according to having at least a signal head not have output potential at mouth along with the disconnection of pilot switch.When the contact of a pilot switch was in the close position for a long time, for example because this contact is sintered, at this moment the signal input part of at least one signal head was carried out on the common reference potential of current and power supply at signal head and switch machine; To produce a corresponding breakdown signal this moment.Even when mistake occurring, respectively by the closing of contact of two auxiliary contactors of single channel control, computer system also can identify this, this be because the input end of two signal heads on reference potential therefore two mouths at signal head do not have signal potential.
Have only when two computer access send execution command and are communicated with two computer access auxiliary contactor, the feeding circuit of switch machine motor is just inserted in the contact of auxiliary contactor, makes to carry out the mobile and switch machine commutation operation of electric current.
Owing to, thereby can realize this supervision with electronically to the persistent surveillance of the on off state of switch machine transit node.The mistake that this electronic switch may occur will be detected and gone out as fault recognition by computer system by signal head.
The fault of running current monitoring device will by computer system when operation commutation next time according to untimely or do not have the running current signal to identify.
Particularly when monitoring current potential in switch machine commutation operation not with the situation of carrying out the voltage stack under, if computing machine constantly, promptly even the words that also signal potential of signal head detected in switch machine when operation commutation, can save and be used to judge that the running current that is undertaken by computing machine of new switch machine terminal location monitors, can judge that according to the appearance computer system of specific signal current potential combination arriving a new terminal location also judges thus, needs monitor the switch machine terminal location immediately.
Identical so the available aforesaid way discovery of effect of the fault of computing machine to the operating part control interface (lasting or lack relay control) and the fault of relay or its contact.
In signal to the fault (signal that lacks or continue) on the computer direction is to go out with the signal aspect and indication beyond the signal format.
In leading to the cable machinery of switch machine, be identified as short circuit between heart yearn until interruption or short circuited longitudinal impedance.Be disconnected according to signal, motor is inoperative, time of run is long or can not the incoming terminal position, can identify longitudinal impedance greater than certain particular value.
Between heart yearn short circuit corresponding when low ohm in transition with the release voltage insurance, between the heart yearn that has different signal voltage current potentials, will cause signal to disconnect during short circuit in addition.Have that short circuit will identify between the heart yearn of same signal current potential after next transition.
Reversal in the three phase mains net of actuating unit feed will be in next control process according to mistake, promptly unexpected signal identifies.Switching by position relay when changing-over is connected on to the heart yearn of switch machine with the phase place identical with last commutation operation through the circuit of reversal.Through the coupling electric machine running, but not conversion of signal, this is because the switch machine transit node does not have changing-over.
