The signal that carries second data item can be the frame form that comprises pulse, and this pulse duration is represented the data of being carried by said signal.In this case, recognition device can confirm these pulse durations and with the different value of corresponding initialize data relatively.
Through the configuration input 32 of processing unit 5, can select and the corresponding configuration of auxiliary equipment operator scheme.SDX configuration corresponding to initialization faulty indication transmission embodiment illustrated in fig. 1 by the change of circuit-breaker state.Yet, can select other configuration through the configuration input, the for example M2C configuration of the trip device initialization faulty indication transmission through said circuit breaker, or the SDTAM of proximity switches assist command disposes.
Processing unit 5 shown in Figure 1 comprises first input end 33, and it receives first data item of the said circuit-breaker state of expression in the SDX configuration that is changed the transmission of initialization faulty indication by the circuit-breaker state.Processing unit 5 also comprises the apparatus for initializing 34 of order output terminal, its in this identical SDX configuration, the order of exporting first data item of transmission expression state according to second data item and first data item.In the SDX configuration that changes the transmission of initialization faulty indication by the circuit-breaker state; In the phase I; When second data item was represented and cause the corresponding electric fault of fault of circuit-breaker main contacts disconnection, processing unit 5 is command transfer second data item preferably, and in second stage; When first data item is represented closed subsequently said circuit-breaker main contacts, the initialization of fill order output.Second data item is generally represented pattern of fever SDT and/or differential-type SDV electric fault.In pattern shown in Figure 1, two order output terminals 7 and 8 send data transfer command through switching device 9 and 11 to two fixed contacts 18 and 19, with the data of transmitting thermoelectric fault SDT discretely and the data of differential electric fault SDV.This auxiliary data transmission equipment list reveals stronger reliability, this be because initialization be by the data of indication circuit circuit-breaker status start and also these data from obtaining from the state transfer device of dropout device separates.
Processing unit also can comprise the time-delay mechanism relevant with apparatus for initializing 35, and when elapsed time between transmission second data item and the closed main contacts is lower than when presetting time-delay, it can the initialization command output.Reference time delay is from 500ms to 1 second, preferably from 300ms to 700ms.This time-delay can guarantee that circuit-breaker has changed state really before reinitializing, can overcome like the spring problem in the contact like this.
Processing unit 51 shown in Figure 2 comprises the choice device that can select the configuration corresponding with specified operation mode.For example arrangement changes function, these selection of configuration devices of Fig. 2 are represented with the form of configure interrupt switch 52 and selection of configuration device switch 53.Clearly, this switch need be with not corresponding like the identifiable material part in the processing unit with selection of configuration device switch.Choice device shown in Figure 2 can be accomplished and select from following configuration:
-at least one SDX configuration by the transmission of circuit-breaker state variation initialization faulty indication.
-the M2C configuration of trip device initialization faulty indication transmission through said circuit-breaker, or
The SDTAM configuration of-proximity switches assist command.
Identical with Fig. 1; Processing unit 51 shown in Figure 2 comprises; The apparatus for initializing 60 of second input 55, the recognition device 56 that is connected to second input, first input end 57, two order output terminals 58 and 59, order output terminal, and the time-delay mechanism 61 corresponding with apparatus for initializing.Except the above element of enumerating and in Fig. 1, having represented with different Reference numerals, processing unit 51 comprises and is used for the element operated at other two kinds of configuration-M2C and SDTAM.For these elements, in SDTAM configuration, can postpone at least one initialization in order output terminal 58 and/or 59 with apparatus for initializing 62 corresponding time-delay mechanisms 61.
The deploy switch 52 of Fig. 2 can be realized being changed and the SDX configuration of initialization faulty indication by the circuit-breaker state with the state of selection of configuration device switch 53 expressions.In this SDX configuration, selection of configuration device switch 53 residing states can make first input end 57 be connected to apparatus for initializing 60 through time-delay mechanism 61.Therefore, represent that first data item of O state or the C state of said circuit-breaker can send the order of initialization command output 58 and 59.Thereby deploy switch 52 is used for making its part to be in off-state makes recognition device break off from apparatus for initializing.Therefore, in this SDX configuration, in the phase I, when second data item was represented and cause the corresponding electric fault of fault of circuit-breaker main contacts disconnection, processing unit sent the order of second data item that obtains on transmission second input 55.In second stage; When obtainable first data item on the first input end 57 is represented closed subsequently said circuit-breaker main contacts; And ought between input 57 transmission second data item and closed main contacts, delay time in short-term than preset time by elapsed time, these processing unit also carry out the initialization of order output terminal.
Fig. 3 a to 3c example in SDX configuration, when perdurabgility of open circuit circuit breaker with electric fault than delay cycle in short-term, the operation of auxiliary equipment.The signal 101 that second input 55 receives is shown in Fig. 3 a, and it carries second data item of expression fault, the fault of in this example, carrying predefined type.This signal comprises pulse 102, and its width can make the predefined type fault obtain identification, for example hot stall SDT or differential fault SDV.T0 breaks down and at t1 constantly or identified rapidly afterwards constantly, promptly pulse 102 trailing edges 103 places constantly the earliest.And the appearance of this type of predetermined failure changes the state of circuit-breaker, promptly breaks off main contacts, and the data of this expression state are transferred to first input end 57.Therefore, shown in Fig. 3 b, the signal 104 that receives on the first input end 57 comprises rising edge 105, and the main contacts of its indication circuit circuit breaker breaks off.This rising edge 105 of signal 104 can occur constantly at t0 immediately.Signal 104 remains on high level, till the t2 that answers with circuit-breaker main contacts closed pair constantly.At t1 constantly, the order of second data item of transmission expression fault is sent to the order output terminal 58 of processing unit.Through switching device, this second data item is transferred to fixed contact or the fixed contact that can indicate the predefined type fault then.Therefore, the voltage 106 on this fixed contact shown in Fig. 3 c constantly becomes high level from low level at t1, exists and the corresponding fault of predefined type fault thereby indicate.Between t1 and t2 elapsed time than the time-delay of time-delay mechanism 61 in short-term, do not carry out on initialization and the fixed contact voltage 106 t2 constantly continued remain high level, shown in Fig. 3 c.When the main contacts of circuit-breaker keeps off-state, the time-delay that its duration is confirmed than time-delay mechanism 61 is not carried out reinitializing order output terminal in short-term.Therefore overcome the spring problem in the contact.
Fig. 4 a to 4c example in SDX configuration, when the perdurabgility of the open circuit circuit breaker with electric fault is longer than time-delay, the operation of auxiliary equipment.The signal 111 that second input 55 receives comprises pulse 112 shown in Fig. 4 a, its width can make the predefined type fault obtain identification, for example hot stall SDT or differential fault SDV.The fault that t0 occurs constantly at t1 constantly or identified rapidly afterwards, promptly trailing edge 113 places of pulse 112 constantly the earliest.The signal 114 that receives on the first input end 57 self partly comprises rising edge 115, and the main contacts of its indication circuit circuit breaker breaks off.Compare with Fig. 3 b, the time that signal 114 high level of Fig. 4 b keep is longer, till the t2 that answers with circuit-breaker main contacts closed pair constantly.Identical with the mode among Fig. 3 c, the voltage 116 on the fixed contact shown in Fig. 4 c constantly becomes high level from low level at t1, exists and the corresponding fault of predefined type fault thereby indicate.But, when elapsed time between t1 and the t2 is longer than time-delay, when first data item is represented subsequently closed main contacts, carry out the initialization of order output terminal.Therefore t2 constantly after, voltage on the fixed contact shown in Fig. 3 c 116 becomes low level from high level.In the SDX pattern, have only and only work as i) if at least in the time-delay of time-delay mechanism 61 main contacts of circuit-breaker break off, and if when ii) these contacts are closed again subsequently, just fill order output initialization again.Therefore time-delay mechanism 61 is guaranteed reinitializing of order output terminal obtained carrying out.
In the M2C configuration that the trip device initialization faulty indication by said circuit-breaker transmits; Deploy switch 52 is in closure state and selector switch 53 is in the state that first input end 57 is fully broken off, and promptly first input end breaks off from time-delay mechanism 61 and 62.In this M2C configuration, in the phase I, when second data item is represented electric fault; Processing unit sends the order of second data item that obtains on transmission second input 55; And when second stage, when second data item is represented to assist initialization command, the initialization of fill order output.
