Ku-orchestration enkulu yamagridi wamandla wesimanje,amamitha ahlakaniphileime njengamathuluzi abalulekile, evala igebe phakathi kokugeleza kwamandla okuvamile, okukodwa nendawo yamandla aguqukayo, asebenzisanayo. Kunokuba zibe izinto ezilinganayo zedijithali zabanduleli bawo be-analog, lawa madivayisi ayinkimbinkimbi angamaphuzu e-nexus wedatha, ukuxhumana, nokulawula. Emnyobeni wokusebenza kwawo ngempumelelo, osebenza njengokuthula, nokho okubalulekile, abaxazululi bokugeleza kwamandla, kukhonaamalayidi. Lawa maswishi e-electromechanical noma e-solid-state angabalindi abangaqashiwe abanikeza amandla amamitha ahlakaniphile ngemisebenzi yawo ebaluleke kakhulu: ukulawula okukude phezu kokunikezwa kwamandla.
Ukufika kwamamitha ahlakaniphile kumemezela inkathi yenguquko ezinsizakalweni nakubathengi ngokufanayo. Inhloso yabo eyisisekelo idlulela ngalé nje kokulinganisa ukusetshenziswa. AInhloso eyinhloko yemitha ehlakaniphileiwukunikeza idatha yesikhathi sangempela noma eseduze nesikhathi sangempela sokusetshenziswa kwamandla kubo bobabili abahlinzeki bosizo kanye nomsebenzisi wokugcina. Leli khono lokuxhumana lezinhlangothi ezimbili linika amandla inqwaba yemisebenzi ethuthukisiwe: ukufundwa kwamamitha ukude, kuqeda isidingo sokuvakashela mathupha; izibalo zokusetshenziswa ezinemininingwane zabathengi ukuze basebenzise ngokugcwele ukusetshenziswa kwabo; futhi, okubaluleke kakhulu, ikhono lezinsiza zokuphatha ukude ukuxhumana kwamandla. Kukulo msebenzi wokugcina, obalulekile lapho ama-relay agcizelela ukubaluleka kwawo okuphambili.
Kuyini ukudluliselwa ku-Smart Meters?
Empeleni, audluliseiyiswishi esebenza ngogesi. Isebenzisa amandla kagesi uma kuqhathaniswa ukuze ilawule amandla amakhulu kakhulu, noma ukushintsha phakathi kwamasekhethi ahlukene. Kumamitha ahlakaniphile, ama-relay ajwayelekileama-relays magnetic latching. Ngokungafani nama-relay okuvamile adinga amandla aqhubekayo ukuze agcine isimo sawo esishintshile (kuphakathi kokuthi VULIWE noma VALIWE), ama-relays azibuthe anomklamo oyingqayizivele ozivumela ukuthi "zixhume" endaweni ngemva kokuthola ishayela kagesi emfushane. Lokhu kusho ukuthi zisebenzisa amandla kuphela ngesikhathi esifushane sokushintsha, okunciphisa kakhulu ukusetshenziswa kwamandla okulindile—isibaluli esibalulekile samadivayisi afana namamitha ahlakaniphile okufanele asebenze ngokuqhubekayo iminyaka.
Lezi zingxenye eziqinile zihlanganiswe ngokuqondile ngaphakathi kwemitha ehlakaniphile, zibekwe ukuze zixhume noma zinqamule ukuhamba kukagesi ezakhiweni. Uma isisetshenziswa sidinga ukuxhuma amandla ekhasimendeni elisha, ukubuyisela isevisi, noma, ezimweni ezithile, ukunqamula isevisi (isb, ngenxa yokungakhokhi noma ngesikhathi sezimo eziphuthumayo), sithumela isignali kumitha ehlakaniphile. Izinto zikagesi zangaphakathi zemitha zitolika lesi siginali bese, ngokulandelayo, zisebenzisa i-relay edidiyelwe ukuze ushintshe intambo yamandla. Lo mdanso oyinkimbinkimbi wamasiginali kanye nesenzo sokusebenza sigcizelela indima yokudlulisela njengesixhumi esibonakalayo phakathi kwemiyalelo yedijithali yensiza kanye nokugeleza okuphathekayo kukagesi.
Izici ezithile zalokhu kudluliselwa zibalulekile ekusebenzeni okuthembekile kwemitha ehlakaniphile. Kufanele bakwazi ukuphatha imithwalo yamanje ebalulekile, ngokuvamile esukela ku-60A ukuya ku-120A, futhi kumele babe namandla aphezulu e-dielectric ukuze bahlukanise ngokuphephile amasekhethi. Ngaphezu kwalokho, ikhono lazo lokumelana nemisinga yesekhethi emifushane ngaphandle kokulondoloza umonakalo noma ukubangela ukwehluleka okuyinhlekelele kubaluleke kakhulu ekuzinzeni nasekuphepheni kwegridi. I-Malio, isibonelo, inikeza ukusebenza okuphezului-magnetic latching relays yamamitha ahlakaniphile, kuhlanganise nokuqina kwazoI-Magnetic Latching Relay(P/N MLLR-2189). Le modeli ethile inezinga eliphezulu lokushintsha elingu-120A kanye nekhono elimangalisayo lokumelana nesilinganiso esiphezulu se-short-circuit yamanje engu-3000A ngo-10ms ngaphandle kokungasebenzi kahle, ngisho no-6000A ngo-10ms ngaphandle kokwehluleka okuyinhlekelele, okugqamisa izimfuno ezinzima ezibekwe kulezi zingxenye.
Uyini Umsebenzi We-Smart Relay?
I-smart relay, kungakhathaliseki ukuthi iyunithi ezimele noma ingxenye eshumekiwe, ingase ihlanganise izici ezifana nalezi:
• Amaphrothokholi Okuxhumana Athuthukisiwe:Ngaphandle kokuthola umyalo olula wokuVULIWA/KUVALIWE, i-smart relay ingase idlulisele isimo sayo ensizeni, iqinisekise ukusebenza ngempumelelo kokushintsha, noma ibike idatha yokuxilonga mayelana nempilo yayo. Lokhu kuxhumana kwezinhlangothi ezimbili kuguqula ukushintshisana kube umhlanganyeli osebenzayo engxoxweni yokusebenza yegridi.
•Ukuqonda Okuthuthukile Nokuhleleka:Amanye ama-smart relay anezilawuli ezincane zangaphakathi, ezivumela ingqondo eyinkimbinkimbi ukuthi ihlelwe ngokuqondile kudivayisi. Lokhu kungase kunike amandla ukushintsha okusekelwe esikhathini, ukucishwa kokulayisha okusekelwe ezimeni zegridi, noma ngisho nokubamba iqhaza ezinhlelweni zokuphendula isidingo, lapho imithwalo engabalulekile inqanyulwa okwesikhashana phakathi nezikhathi zokufunwa okuphezulu.
•Ukutholwa Kwephutha Nokuvikelwa:I-smart relay ingase yakhelwe ukuthola okudidayo ekuhambeni kwamandla, njengama-overcurrents noma ama-short circuit, futhi izihambe ngokuzenzakalelayo ukuze kuvikelwe imitha nezinto zikagesi ezixhunyiwe. Lo msebenzi wokuvikela osebenzayo udlulela ngalé kokushintsha okulula, okungeza ungqimba lokuphepha nokuthembeka.
•Amandla Okuqapha Amandla:Nakuba imitha ehlakaniphile ngokwayo iyisisetshenziswa esiyinhloko sokulinganisa amandla, okunye ukudluliselwa okuhlakaniphile kungase kuhlanganise inzwa yamanje engavamile noma i-voltage ukuze kunikezwe idatha yendawo, kuthuthukise ukuqonda kwegridi yokusabalalisa amandla.
•Ukuxilongwa kwesilawuli kude kanye nokuziphilisa:Ama-smart relay athuthuke kakhulu angakwazi ukuzihlola, ahlonze ukwehluleka okungenzeka, futhi aze adlulisele lezi zinkinga kunsizakalo, enze ukunakekelwa okubikezelwayo futhi anciphise isikhathi sokuphumula. Le ndlela yokusheshisa ukulungisa isisekelo sokuphathwa kwegridi okuhlakaniphile.
Kumongo wamamitha ahlakaniphile, kuyilapho ama-relay amagnetic latching ngokwawo eyinkimbinkimbi, "ubuhlakani" ngokuvamile buvela kuyunithi yokulawula ebanzi yemitha ehlela ukuziphatha kokudlulisela okusekelwe kumasignali angenayo kanye nengqondo ehleliwe. I-relay isebenza njengengalo yesigungu esiqinile, yenza ngokwethembeka imiyalo ekhishwe ubuhlakani obuhlanganisiwe bemitha. Uhlu olubanzi lukaMalio lweamalayidikuma-smart metres ayisibonelo salokhu, kusukela kumthamo omkhulu we-120A okuhlukile kuya kokuguquguqukayoI-Magnetic Latching Relays. Lawa madivayisi aklanyelwe ukushintshwa okunembayo nokuqina okukhethekile, akwazi ukubekezelela ukusebenza kukagesi okungu-100,000 futhi abonise ukumelana nokuthintana okuncane (0.6mΩ), okuqinisekisa ukudluliswa kwamandla okuphumelelayo ngaphandle kokulahlekelwa okungenakuphikiswa okungadingekile.
Ukuthembeka kwalokhu kudluliselwa phambili kubaluleke kakhulu. Ukudluliselwa okungalungile kungaholela ekuphazamisekeni kwesevisi, ekukhokheni okungalungile, noma ngisho nasezingozini zokuphepha. Ngakho-ke, abakhiqizi abanjengoMalio bagcizelela ukuhlola okuqinile kanye nezinto zokwakha zekhwalithi ephezulu, njenge-AgSnO2 yoxhumana nabo, okuqinisekisa ukumelana nokuxhumana okuphansi nempilo ende yokusebenza. Ukucaciswa okudingekayo, njengamandla e-dielectric aphezulu (AC4,000V phakathi kwekhoyili noxhumana nabo) kanye namazinga okushisa okusebenza abanzi (-40℃ kuya ku-+85℃), akuzona nje izinto zobuchwepheshe; ziyizimfuneko eziyisisekelo zokuqinisekisa ukuthi lezi zingxenye ezingabonakali zisebenza kahle iminyaka eminingi ezindaweni ezihlukahlukene nezivame ukuba yinselele lapho kusetshenziswa khona amamitha ahlakaniphile.
Empeleni, ama-relay angabali abanamandla, abaphathekayo bemiyalo yedijithali yemitha ehlakaniphile. Ziyimisipha engaculwa, eyimishini ngemuva kobuchopho bobuhlakani begridi. Ngaphandle kwesenzo sazo esinokwethenjelwa, ukuhlaziya idatha okuyinkimbinkimbi namandla okuxhumana amamitha ahlakaniphile kuzohlala kuyithiyori. Njengoba umhlaba uguqukela kumagridi wamandla ahlakaniphile, esimeme kakhudlwana, futhi aqine kakhudlwana, ukudluliselwa kwamandla okuthobekile kodwa okunamandla kuzoqhubeka nokudlala indima ebaluleke kakhulu, kuqinisekiswe ukugeleza kwamandla okungenazihibe nokukhalipha okuqinisa ukuphila kwethu okuxhumene.
