Definitions

  • the invention is in the field of electrical switches, in particular the switchgear for high or medium voltage. Aspects of the invention relate to a method for determining wear of a contact element of such a switch. Further aspects of the invention relate to an electronic unit for an electrical switch.
  • Circuit breakers are subject to constant wear and should therefore be inspected and maintained regularly.
  • the arc occurring during a switching operation leads to material wear of the contact pieces and thus contributes considerably to wear.
  • contacts can not be easily verified without costly disassembly and shutdown of performance.
  • a periodic circuit breaker maintenance is made, possibly with early maintenance, when high-level protection trips have occurred. This usually waits for the switch too often. Maintenance causes avoidable costs and an additional risk of causing damage during maintenance.
  • the maintenance intervals are too great, there is a risk that wear or contact wear will not be detected early.
  • EP 1475813 A1 describes methods for determining contact wear in electrical switchgear for high or medium voltage, one during a Switching action is detected by the contact current flowing through the switch with the aid of a current transformer and is evaluated with respect to contact wear.
  • a current measurement signal of the current transformer is first measured as a function of time; if deviations occur between the expected contact current and the current measurement signal, the presence of a measurement error is detected, and upon detection of the measurement error, the current measurement signal becomes at least one characteristic current value determined and used to determine the state quantity.
  • DE 10204849 A1 describes a method for determining contact wear.
  • a method for determining a wear of a contact element of an electrical switch eg a vacuum switch, in particular a switchgear for high or medium voltage.
  • the method comprises detecting electrical values representative of an electrical quantity relevant to an arc occurring during a switching action on the switch as a function of time, the electrical values being detected, for example, as a continuous function or as a data series (vector) with discretely sampled values may include but also virtual values, eg (partially) simulated, interpolated, or fitted values, in which case virtual values are detected.
  • the electrical values are current values representing a contact current flowing through the switch during a switching operation as a function of time.
  • the method further comprises calculating a wear value representing the wear of the contact element from a plurality of wear contribution values, wherein the wear contribution values are calculated from a plurality of value subsets of the detected electrical values using a plurality of wear contribution calculation rules such that each of the wear contribution values a respective one of the wear contribution calculation rules is calculated from a respective one of the value subsets, and wherein at least two of the wear contribution calculation rules differ from each other.
  • a subset of values is understood to include all detected electrical values.
  • an electronic unit in particular a control and / or monitoring system, is provided for an electrical switch (for example a vacuum switch), in particular for a switchgear for high or medium voltage.
  • the electronic unit includes a value input module for obtaining electrical values (e.g., current values) representing an electrical quantity relevant to an arc occurring during a switching action on the switch as a function of time.
  • the value input module can thus be e.g. for obtaining detected electrical values from a value meter, but possibly also from (electrical) simulating or interpolating, etc. of detected electrical values.
  • the electronic unit further comprises a wear determination module having a computing unit and a data memory with program code executable by the computing unit.
  • the program code includes a plurality of wear contribution calculation rules that are provided for calculating respective wear contribution values from respective value subsets of the detected electric values, at least two of the wear contribution calculation rules differ from each other, and a wear value calculation routine for calculating the wear of the contact element representing the wear value from the wear contribution values.
  • the program code includes rules for carrying out any of the methods mentioned herein.
  • the invention also relates to an apparatus for carrying out the disclosed methods and also comprises apparatus parts for carrying out individual ones Process steps. These method steps may be performed by hardware components, by a computer programmed by appropriate software, by a combination of both, or in some other way.
  • the invention is further directed to methods according to which the devices described in each case operate. It includes method steps for performing each function of the devices.
  • the wear contributions can also be calculated from other electrical values.
  • electrical values are understood to be any values of variables which are relevant for an arc occurring during a switching operation on the switch.
  • the electrical values may be current values, voltage values, and / or combinations thereof (e.g., arc power levels formed by a product of current and voltage).
  • the calculation instructions mentioned here, based on the current can also be applied analogously on the basis of such further electrical values by replacing the current values I in the same calculation rules with the other electrical values.
  • Electrical switches such as e.g. used as a circuit breaker in a switchgear for high or medium voltage, usually have two or more contacts. When the switch is closed, these contacts are in electrically conductive direct contact with each other. When opening the switch, the contact pieces are moved away from each other and separated, so that no more current can flow from one contact piece to the other contact piece. If a current flows during the switching operation, the current flow is not immediately completely interrupted during the separation of the two contact pieces from each other, but an arc is formed between the two contact pieces, which carries the current for a certain time. Such an arc also occurs with circuit breakers, i.
  • switch types designed to switch under load, and more particularly for high voltage circuit breakers (i.e., voltages greater than 50 kV, for example 50-800 kV) or medium voltage (i.e., voltages of 5 kV to 50 kV).
  • high voltage circuit breakers i.e., voltages greater than 50 kV, for example 50-800 kV
  • medium voltage i.e., voltages of 5 kV to 50 kV.
  • FIG. 4 Such a switching operation under load with arc is in Fig. 4 illustrated by the example of a vacuum circuit breaker.
  • the vacuum circuit breaker 1 has a first contact piece 10 and a second contact piece 20.
  • the contact pieces 10, 20 each have a shaft 12, 22 and a contact plate 14, 24 arranged at the distal end of the shaft.
  • the contact plate 14, 24 of each of the contact pieces 10, 20 each has a contact surface which contacts a corresponding contact surface of the other contact piece directly when the switch is closed.
  • Define the two contact pieces 10, 20 a switching axis along which they can be moved apart to open the switch relative to each other. In Fig. 4 this axis is the vertical.
  • Fig. 4 the switch 1 is shown during opening, and the contact pieces 10, 20 are already separated from each other along the switching axis.
  • the interruption of the stream is in Fig. 4 not yet completed, and an arc 33 is formed between the contact pieces 10 and 20.
  • a current still flows from the first contact piece 10 to the second contact piece.
  • the current flows via the shaft 12 (current path 31a), via the contact plate 14 (current path 31b), then via the arc 33, and via the contact plate 24 (current path 31c) and via the shaft 22.
  • Arc is removed material of the contact pieces (this material usually forms the plasma of the arc), resulting in wear of the contact pieces.
  • the contact pieces 10, 20 designed as a TMF type means that the contact pieces are designed so that the switching current during a switching operation a predominantly transverse magnetic field (perpendicular to the general current flow direction or to a main direction of the arc, ie parallel to a surface defined by the contact surfaces 14 and 24 ). This is achieved here by slots in the contact plates 14 and 24.
  • the slots provide such a current flow direction of the current 31b, 31c in the plates that the current is a transverse magnetic field (in Fig. 4 in the horizontal plane).
  • the in Fig. 4 The switch shown is of the spiral type (ie with helically shaped slots).
  • Other forms of contact pieces are possible.
  • One possible alternative form for TMF-type switches is, for example, cup-shaped contacts.
  • the in Fig. 4 shown switch is a vacuum circuit breaker (ie with a negative pressure in the switch room, in which an arc is expected, in particular with a high vacuum).
  • a vacuum circuit breaker ie with a negative pressure in the switch room, in which an arc is expected, in particular with a high vacuum.
  • aspects of the invention may relate to eg a shielding gas circuit breaker in which the switch compartment is filled with a shielding gas such as SF 6 .
  • a difficulty with switches and in particular with circuit breakers is the wear of the contact pieces (eg contact pieces 10, 20 in Fig. 4 ) through the arc (33 in Fig. 4 ).
  • the problems caused by the wear or the associated wear of the switch are already described above. For the reasons mentioned above, it is desirable to determine the wear as accurately as possible.
  • the wear is indicated by a thickness d (in mm) by which material is removed from the contact surface of the contact piece due to the arc during a switching operation.
  • I (t) represents the contact current flowing through the switch during a switching operation as a function of time t, ie, the current flowing through the arc 33 at time t Fig. 4
  • k and ⁇ are constants that can be determined, for example, by a model or empirically.
  • the time integral in (1) refers to the total switching time during which an arc is present.
  • Eq. (1) Also express a sum for discrete current values that approximates such an integral appropriately.
  • the calculation rule (1) provides inaccurate results, especially for medium or high switching currents. If the parameters k and ⁇ are calibrated for low switching currents, the wear for high switching currents and long arc lengths (phase length 0.75 ⁇ and more) tends to be overestimated by rule (1), and the wear for medium or high switching currents and short arc lengths ( Phase length 0.25 ⁇ and less) tends to be underestimated. Therefore, the question arises of a more realistic or more precise rule to determine the wear d also for a wide range of switching currents and arc lengths. For this purpose, one might be led to replace the integrand in (1) with a more complex expression (with more parameters to be adjusted empirically). However, the accuracy achievable with such an approach is also limited and can not justify the increase in the number of parameters to be adjusted.
  • the current values I (t) which represent the contact current flowing through the switch during a switching operation, are detected as a function of the time t.
  • the current values I (t) can be detected as a continuous function or as a data series (vector) with discretely sampled values.
  • the sampled current values may include not only measured values but also virtual values, e.g. include simulated, interpolated or fit values based on the measurements and / or a suitable model.
  • the current may be assumed to be sinusoidal, and the amplitude and phase and, if necessary, frequency of the signal may be adjusted based on measured values to give a good match of the sinusoidal current with the measured values.
  • the wear contribution values d i are in turn calculated using a plurality of wear contribution calculation rules f i from a plurality of current value subsets of the detected current values I (t) such that each of the wear contribution values according to a respective one of the wear contribution calculation rules f i is from a respective one of the wear contribution values f i
  • Current value subsets is calculated (a sub-set of current values may also include all detected current values, ie may be a real or a spurious subset). At least two of the wear contribution calculation rules differ from each other (as functionals or mappings).
  • One aspect of the invention is based on the recognition that different arc phases occur during a switching operation. These arc phases follow each other in time. These different arc phases lead to different wear of the contact pieces, ie the wear depends, depending on the arc phase, in different ways from the current: While about a diffuse arc leads to a more uniform and low wear of different parts of the contact leads a stationary laced electric arc results in an intensive wear of a limited part of the contact piece, and thus is more relevant for wear overall.
  • the method according to the invention advantageously makes it possible to calculate the contribution of different arc phases for the wear of the contact element as a respective own wear contribution value.
  • Each of the wear contribution values may be calculated by means of a wear contribution calculation rule specific to each arc phase. For this purpose, it is advantageous to select the current value subsets and / or the wear contribution calculation rules such that a certain detected current value, depending on in which arc phase it occurs, leads to a respective different wear contribution.
  • the respective current value subsets As current value subsets, those current values that belong to a respective arc phase can be determined.
  • the time intervals for the respective arc phases can be determined (eg, for the i-th arc phase, the time interval [t i ; t ' i ] from t i to t' i ), and the current value subsets than those at the respective time interval [ t i ; t ' i ] corresponding current values current value subsets I ([t i ; t' i ]) are selected.
  • the limit times t i , t ' i are suitably determined for the respective arc phase (see below), and the current value subsets are defined taking these times into account.
  • the temporal delimitation between the individual arc phases can be somewhat blurred, with transitional periods in between. Nevertheless, one can at least approximately determine a limit time for the boundary (beginning or end) of a phase, ie t i for the beginning or t ' i for the end of the ith arc phase.
  • a limit time may be either a start time for the start of the arc (or the first arc phase), or a transition time for the transition from one phase to a respective next phase, or an end time for the end of the arc (or the last arc phase). Accordingly, the transitional time does not refer to the beginning or the end of the arc as such, since no different arc phases merge here.
  • a start timing t 0 (or, more specifically, t open ) for the beginning of the diffused arc
  • a transition timing t ' 0 t 1 for the transition from the diffuse arc to the diffused arc tied stationary arc
  • another transition time t ' 1 t 2 for the transition from the laced stationary arc to the traveling arc
  • the current value subsets may be used as first, second and third current value subset I ([t 0 ; t ' 0 ]), I ([t i ; t' i ]), I ( [t 2 ; t ' 2 ]).
  • Fig. 1a and 1b describe how the limit times that limit the arc phases, can be determined in detail.
  • Fig. 1a and 1b shows diagrams with the current I occurring during a switching operation ( Fig. 1a , vertical axis) or the arc voltage U ( Fig. 1b , vertical axis) as a function of time t (horizontal axis).
  • the times t 0 to t 3 are in Fig. 1a and 1b in slightly different positions.
  • the current generally has a roughly sinusoidal shape, with an envelope modulated to a fundamental frequency.
  • Fig. 1a and 1b only a part of a sinusoidal oscillation period is shown, with a zero crossing before the time t 0 .
  • the switch controller Due to this overcurrent, the switch controller outputs a switching signal, which causes the separation of the contact pieces of the switch. A short time thereafter, the switch controller outputs a switching signal, which causes the separation of the contact pieces of the switch. The contacts are then moved apart and separate at about time t 0 . This separation is recognizable by the fact that in Fig. 1b the voltage suddenly rises and an arc occurs. At about the same time, the arc starts as a diffuse arc. As the beginning of the diffuse arc (1st arc phase), which defines the time t 0 , the separation of the contact pieces or the in Fig. 1b recognizable increase in voltage can be used. In some embodiments, the low contact wear during the diffuse arc phase may be neglected.
  • the diffuse arc transitions into a laced stationary arc.
  • This transition can be detected, for example, by the current exceeding a predetermined current threshold I constr .
  • I constr The exact choice of the threshold value I constr depends on the geometry of the contact pieces and on further details, and can be calibrated by measurements, for example. Several observations have shown that I constr can generally be more than 10 kA, ie 15 kA. Alternatively, the transition into the laced stationary arc may be defined otherwise. Other possible alternatives for determination are described below.
  • the stationary arc passes into a moving arc under the influence of the transverse magnetic field generated by the flowing current.
  • the movement of the arc leads to an increased noise component of the measured voltage and the measured current. Therefore, the transition to the moving arc can be detected by the noise component of the voltage (ratio of the variance in a given frequency range to an averaged value of the voltage) exceeding a predetermined threshold.
  • the exact choice of the frequency range and the threshold value depends on the geometry of the contact pieces and on further details, eg the evaluation of the noise signal is particularly meaningful for the spiral TMF type.
  • the threshold etc. can be calibrated by measurements, for example.
  • the transition into the necked stationary arc may be defined in other ways, as described below.
  • This point in time can be recognized, for example, by the fact that the current drops significantly. More generally, the time t 3 may be defined by a decrease in current and / or voltage below a predetermined threshold.
  • the limit time may in particular be selected as the time of a corresponding event.
  • the limit time can also be calculated considering several of the mentioned events, for example by logical or weighted linking of several events or by averaging several corresponding times.
  • the limit timing is a transient time representing a transition from a stationary arc state to a traveling arc state.
  • elements from the above list can be selected and the determination rules for a respective arc phase can be suitably calibrated.
  • several investigative procedures can be applied and their results combined, e.g. by averaging or forming a weighted average.
  • the respective time intervals for the current value subsets may be determined, for example, in the following manner: No. Arc phase Criterion for determining the beginning of the phase 0 Diffuser arc Separation of the contact pieces (eg determined by evaluation of a switching command or by means of mechanical sensors) 1 Constricted stationary arc Contact current exceeds a threshold Iconstr, eg 10 kA 2 Laced up rotating arc Noise of the current or voltage exceeds a threshold value
  • the end of the laced rotating arc (phase 2) may be e.g. be determined by the fact that the current falls below a predetermined threshold again.
  • the current values may be divided into different current value subsets based on the determined limit times.
  • a first current value subset comprises the current values I ([t 0 ; t 1 ]) in the time interval [t 0 ; t 1 ] (reference number 1).
