Description
Technical field
The embodiment of the present invention relates to technical field of electric power, particularly relates to a kind of control method and device.
Background technology
Relay is a kind of electric control device, comprise open type, closed type and conversion hysteria relay, be widely used in remote control, remote measurement, communication, automatically control, electromechanical integration and power electronic equipment, in practical application, usually adopt series relay to ensure the reliability of relay.When meeting the trigger condition of series relay, series relay carries out circuit communication that operation response makes relay two ends connect or disconnection, and this operation response can comprise closing contact or break contact.Under normal circumstances, if n (n be greater than or equal to 2 integer) series connection of individual relay, then when the mutual dead circuit in series relay two ends is communicated with by the operation response of series relay, 1st to (n-1)th relay carrying out operation response makes to there is not voltage difference between contact because circuit disconnects, thus not charged operation response is carried out, n-th relay carrying out operation response makes to there is voltage difference between contact due to circuit communication, thus carries out charged operation response; When the circuit be interconnected when series relay two ends is disconnected by the operation response of series relay, 1st relay carrying out operation response makes to there is voltage difference between contact due to circuit communication, thus charged operation response is carried out, 2nd makes to there is not voltage difference between contact to the n-th relay carrying out operation response because circuit disconnects, thus carries out not charged operation response.
The order of carrying out operation response due to the relay in series relay in prior art is again fixing, thus makes the some relays in series relay carry out charged operation response for a long time or carry out not charged operation response for a long time.Such as, when the inverter mutually disconnected and grid-connected carry out circuit communication by the open type series relay of two shown in Fig. 1 time, fixing first closing relay K1, rear closing relay K2, then K1 is long-term not charged closed, and K2 is long-term charged closed.The relay (such as K1) carrying out not charged operation response for a long time makes the air oxidation film of contact surface because can not continued accumulation by thoroughly puncturing always, thus increases contact resistance, causes heating of contact serious, thus reduces reliability.And the relay (such as K2) of long-term charged operation response makes contact melt because of generation electric arc and impulse current, gasify, thus reduce reliability.
For carrying out not charged closed single relay for a long time, a small electric pressure reduction ∣ V3-V4 ∣ is increased by Buck conversion circuit as shown in Figure 2 at relay two ends in prior art, thus the oxide-film of arc through contact can be produced when closed, avoid the persistent accumulation of oxide-film, improve the reliability of relay K 3; And for carrying out charged closed single relay for a long time, by the voltage difference at two ends, contact being reduced to the method for an appropriate value in prior art, reduce the intensity of impulse current, reduce arc energy, improve the reliability of relay.But above two kinds of methods can only be respectively used to the reliability improving single relay usually, series relay scene can not be applied to meet the reliability requirement to series relay.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Relay can comprise normal-open type relay, closed type relay and conversion hysteria relay.Wherein, normal-open type relay comprises two contacts, and when no power, two contacts disconnect, two closings of contact after energising.Closed type relay also comprises two contacts, and when no power, two contacts are closed, and after energising, two contacts disconnect.Conversion hysteria relay comprises three contacts, and centre is moving contact, upper and lower each fixed contact, and when no power, moving contact and the first fixed contact close, and disconnect with the second fixed contact, and energising late contact and the first fixed contact disconnect, and close with the second fixed contact.Because relay can comprise above three types, at least two relays of thus connecting successively in series relay group also can comprise in above three types one or more.
Specifically, when the mutual dead circuit in series relay group two ends needs to be communicated with by the operation response of series relay group repeat circuit, in series relay group, the operation response of normal-open type relay is closing contact, the operation response of closed type relay is off contact, and the operation response of conversion hysteria relay is off moving contact and the first fixed contact closed moving contact and the second fixed contact again.When the circuit be interconnected when series relay group two ends needs to be disconnected by the operation response of series relay group repeat circuit, in series relay group, the operation response of normal-open type relay is off contact, the operation response of closed type relay is closing contact, and the operation response of conversion hysteria relay is first disconnect moving contact and the second fixed contact closed moving contact and the first fixed contact again.
Again due under normal circumstances, when the mutual dead circuit in series relay two ends is communicated with by the operation response of series relay, thus last relay carrying out operation response carries out charged operation response owing to making to there is voltage difference between contact after circuit communication, and the relay before carrying out operation response makes there is not voltage difference between contact because circuit disconnects and thus carries out not charged operation response; When the circuit be interconnected when series relay two ends is disconnected by the operation response of series relay, thus 1st relay carrying out operation response carry out charged operation response because circuit communication makes to there is voltage difference between contact, and the follow-up relay carrying out operation response makes there is not voltage difference between contact because circuit disconnects and thus carries out not charged operation response.
Thus, when the mutual dead circuit in series relay two ends is communicated with by the operation response of series relay, if normal-open type relay is last carry out the relay of operation response, then this relay carries out charged closed, if not last carries out the relay of operation response, then carry out not charged closed; If closed type relay is last carry out the relay of operation response, then this relay carries out charged disconnection, if not last carries out the relay of operation response, then carries out not charged disconnection; If conversion hysteria relay is last carry out the relay of operation response, then this relay first carries out not charged disconnection, then carries out charged closed, if not last carries out the relay of operation response, then first carry out not charged disconnection, then carry out not charged closed.
Equally, when the circuit be interconnected when series relay two ends is disconnected by the operation response of series relay, if normal-open type relay is the 1st relay carrying out operation response, then this relay carries out charged disconnection, if not the 1st relay carrying out operation response, then carry out not charged disconnection; If closed type relay is the 1st relay carrying out operation response, then this relay carries out charged closed, if not the 1st relay carrying out operation response, then carries out not charged closed; If conversion hysteria relay is the 1st relay carrying out operation response, then this relay first carries out charged disconnection, then carries out not charged closed, if not the 1st relay carrying out operation response, then first carries out not charged disconnection, then carries out not charged closed.
The embodiment of the present invention provides a kind of control method, and see Fig. 3, its key step can comprise:
101, control device determines whether the trigger condition meeting series relay group, and series relay group comprises at least two relays of connecting successively.
Wherein, control device here can be computer, intelligent control chip equal controller.In this step, control device can determine whether the trigger condition meeting series relay group, this trigger condition refers to that the relay triggered in series relay group carries out operation response, thus the circuit communication making series relay group two ends connect or disconnection is pre-conditioned, specifically can set according to actual needs.
Exemplary, series relay group can be applied in grid-connected inverters process, and one end of series relay group can be connected with inverter, and the other end can be connected with electrical network.Under this application scenarios, when the difference of the voltage that trigger condition can export for inverter and line voltage is less than assign thresholds (such as 30V), be communicated with inverter circuit and the mains-power circuit of series relay two ends connection; When the voltage of inverter output and the difference of line voltage are greater than assign thresholds, disconnect inverter circuit and the mains-power circuit of the connection of series relay two ends.Control device can be monitored the voltage condition of inverter and compared with line voltage, thus be determined whether to meet trigger condition.
If 102 determine it is that then control device controls according to preset rules the order that series relay group repeat circuit carries out operation response, and operation response comprises closing contact or break contact.
When control device is determined to meet trigger condition, the relay that control device can control in series relay group carries out operation response, here operation response can comprise closing contact or break contact, and the concrete operation response that dissimilar relay carries out when meeting trigger condition is different.
The order of carrying out operation response due to the relay in series relay group in prior art is fixing, thus the relay carrying out not charged operation response needs to carry out not charged operation response for a long time, and the relay carrying out charged operation response needs to carry out charged operation response for a long time.And the air oxidation film carrying out the contact surface of the relay of not charged operation response for a long time can be continued accumulation because never thoroughly puncturing, increasing contact resistance thus causing heating of contact serious, thus reducing the reliability of relay.Melting because of generation electric arc and impulse current, gasify in the contact of carrying out the relay of charged operation response for a long time, thus reduces the reliability of relay.
In order to the problem that the reliability solving the relay in prior art in series relay group is low, control device in the embodiment of the present invention controls according to preset rules the order that series relay group repeat circuit carries out operation response, the sequencing making the relay in series relay group carry out operation response can be arranged flexibly, thus the relay in series relay group can be interlocked carry out charged operation response and not charged operation response, and some relays can not be made to carry out charged operation response for a long time or carry out not charged operation response for a long time.Thus the persistent accumulation due to oxide-film between the contact of carrying out the relay of not charged operation response for a long time that causes of operation response order of fixing series relay group repeat circuit in prior art can be avoided, prevent resistance from continuing to increase thus affect the useful life of relay, and can by multiple relays of sharing the damage that contact is caused because of electric arc and impulse current during charged operation response in series relay group, thus extend the life-span of arbitrary relay in series relay group, improve the global reliability of arbitrary relay and series relay group in series relay group.Thus it is fixing for can solving the order of carrying out operation response due to series relay group repeat circuit in prior art, relay is made to carry out charged operation response for a long time or carry out not charged operation response for a long time, thus the problem that the relay reliability caused is low.
Alternatively, the order that control device carries out operation response according to preset rules control series relay group repeat circuit can comprise: the mark that control device random alignment series relay group repeat circuit is corresponding respectively, the ordering control relay corresponding according to mark carries out operation response successively.
When meeting trigger condition, control device can distinguish corresponding mark by random alignment series relay group repeat circuit, exemplary, here mark can be numeral number, alphabetical designation etc. in order to identify the identify label of relay, and the ordering control relay corresponding according to mark carries out operation response successively.Wherein, for arbitrary ordering, control device controls to come relay in front and first carries out operation response, carries out operation response after coming the relay of back.Due to random alignment process, that arbitrary relay in series relay group can be made to be aligned to last probability is equal again, namely arbitrary relay can be made finally to carry out the probability of operation response equal, thus arbitrary relay can be made to carry out the probability of charged operation response (or not charged operation response) equal, thus can charged operation response or not charged operation response be shared to each relay to the damage that contact is caused, avoid a certain relay premature breakdown, thus improve the reliability of arbitrary relay in series relay group.
Exemplary, if series relay group comprises relay K 1 as shown in Figure 1 and relay K 2, wherein, K1 and K2 is respectively the mark that in series relay group, two relays are corresponding, then the concrete grammar of control device random alignment K1 and K2 can be: relay K 1 can be corresponded to numerical intervals [0 by control device, 0.5), and relay K 2 is corresponded to numerical intervals [0.5, 1), when determining to meet trigger condition, control device can produce one [0, 1) random number between, if the random number produced is less than 0.5, then ordering is K1, K2, control device according to this ordering first control relay K1 carry out operation response, then control relay K2 carries out operation response, otherwise, if produce random number be greater than or equal to 0.5, then ordering is K2, K1, control device according to this ordering first control relay K2 carry out operation response, then control relay K1 carries out operation response.
Alternatively, the order that control device carries out operation response according to preset rules control series relay group repeat circuit can comprise: control device chooses the element in default ordering set according to preset rules, this element is the ordering of the mark that series relay group repeat circuit is corresponding respectively, and the ordering control relay corresponding according to the element chosen carries out the order of operation response.
Concrete, control device can preset ordering set, element in this set is the ordering of the mark that series relay group repeat circuit is corresponding respectively, when determining to meet trigger condition, control device can choose the element in default ordering set according to preset rules, thus controls corresponding relay according to the ordering of relay corresponding to the element chosen and carry out operation response successively.For the arbitrary ordering chosen, control device controls to come relay in front and first carries out operation response, carries out operation response after coming the relay of back.
Exemplary, if series relay group is series relay K1 as shown in Figure 1 and relay K 2, the ordering set then preset can be { (K1, K2), (K2, K1) }, the mark K1 that the element in the ordering set preset and series relay group repeat circuit are corresponding respectively, the ordering of K2 can be respectively (K1, K2), (K2, K1).Such as, when control device chooses element (K2, K1), control relay K2 first carries out operation response, carries out operation response after control relay K1.
Exemplary, if series relay group comprises relay K 1, relay K 2 and relay K 3, then the ordering set preset can be { (K1, K2, K3), (K2, K1, K3), (K3, K2, K1), (K1, K3, K2), (K2, K3, K1), (K3, K1, K2) }, the element chosen when control device is (K2, K3, K1), then carry out operation response successively according to ordering control relay K2, relay K 3 and relay K 1 that this element is corresponding.
Certainly, the embodiment of the present invention does not limit the number of series relay group repeat circuit and type.
It should be noted that, control device can by all possible ordering of the mark of the mode limit series relay group repeat circuit difference correspondence of permutation and combination in default ordering set, so that control device is when carrying out operation response according to this ordering relay controlled in series relay group, arbitrary relay in series relay group can be made to carry out the probability of charged operation response (or not charged operation response) equal as far as possible, thus can charged operation response or not charged operation response be shared to each relay to the damage that contact is caused, avoid a certain relay premature breakdown, thus improve the reliability of arbitrary relay in series relay group.
Alternatively, the element that control device is chosen in default ordering set according to preset rules can comprise: when control device equals frequency threshold value according to the number of times that the current control of element relay chosen carries out operation response, again choose the element in default ordering set.
When control device controls the operation response order of series relay group repeat circuit according to the ordering that the current element chosen is corresponding, when the number of times sum making all relays in series relay group carry out operation response equals preset times threshold value, again the element in default ordering set can be chosen, thus according to the operation response order of ordering control relay corresponding to the element again chosen, arbitrary relay in series relay group can be made to carry out the probability of charged operation response (or not charged operation response) equal as far as possible, the frequency threshold value wherein preset can set as required, it can be such as n time, 3*n is inferior, wherein n is the number of series relay group repeat circuit.
Or, when control device controls the operation response order of series relay group repeat circuit according to the ordering that the current element chosen is corresponding, when the number of times making arbitrary relay carry out operation response equals preset times threshold value, again the element in default ordering set can be chosen, thus according to the operation response order of ordering control relay corresponding to the element again chosen, the frequency threshold value wherein preset can set as required, such as, can be 1 time, 3 inferior.
Alternatively, the element that control device is chosen in default ordering set according to preset rules can comprise: when control device is greater than or equal to time threshold according to the time that the current control of element relay chosen carries out operation response, again choose the element in default ordering set.
Being greater than or equal to preset time threshold when control device to control the response order of series relay group repeat circuit time according to ordering corresponding to the current element chosen (can be such as 1 day, specifically can set as required) time, again the element in default ordering set can be chosen, thus according to the operation response order of ordering control relay corresponding to the element again chosen, relay can be made all identical according to the time of carrying out operation response of putting in order that arbitrary element in the ordering set preset is corresponding, thus it is equal to make arbitrary relay in series relay group carry out the probability of charged operation response (or not charged operation response) as far as possible, thus can charged operation response or not charged operation response be shared to each relay to the damage that contact is caused, avoid a certain relay premature breakdown, thus improve the reliability of arbitrary relay in series relay group.
Wherein, when the element in default ordering set chosen again by control device, can an element in this set of random selecting; Or also can choose in this set the element come after the current element chosen, the element chosen if current comes a last element in this set, then the element that control device is chosen again is first element in this set.
It should be noted that, the method for the element chosen in default ordering set according to preset rules in the embodiment of the present invention only illustrates, not as the restriction of protection range.
Certainly, control device can also adopt other method control series relay group repeat circuit to carry out the order of operation response, and the embodiment of the present invention does not limit.
