M'magulu oimba amagetsi amakono,smart mitaimayima ngati zida zofunika kwambiri, kutsekereza kusiyana pakati pa kayendedwe ka mphamvu zachikhalidwe, zamtundu uliwonse ndi mawonekedwe amphamvu amphamvu. M'malo mongokhala zofanana ndi zomwe zidalipo kale, zida zapamwambazi ndizomwe zimalumikizana ndi data, kulumikizana, ndi kuwongolera. Pakatikati pa mphamvu zawo zogwirira ntchito, zomwe zimakhala chete, koma ndizofunikira, zotsutsana ndi kayendetsedwe ka mphamvu, ndizo.maulendo. Zosintha zama electromechanical kapena solid-state izi ndi zowongolera zosagwiritsidwa ntchito zomwe zimapatsa mphamvu mamita anzeru ndi magwiridwe antchito ofunikira kwambiri: kuwongolera kutali pamagetsi.
Kubwera kwa ma smart metres kumabweretsa kusintha kwazinthu zofunikira komanso ogula. Cholinga chawo chachikulu chimangowonjezera kuchuluka kwa madzi. ACholinga chachikulu cha mita yanzerundikupereka nthawi yeniyeni kapena pafupi ndi nthawi yeniyeni yogwiritsira ntchito mphamvu kwa onse omwe amapereka chithandizo komanso wogwiritsa ntchito mapeto. Kuthekera kolumikizirana kwapawiri kumeneku kumathandizira kuti pakhale ntchito zambiri zapamwamba: kuwerenga kwakutali kwa mita, kuthetsa kufunikira kwa maulendo apamanja; kusanthula kwatsatanetsatane kwa ogwiritsa ntchito kuti ogula akwaniritse bwino ntchito yawo; ndipo, chofunikira kwambiri, kuthekera kwazinthu zothandizira kuwongolera maulumikizidwe amagetsi patali. Ndi mu ntchito yomaliza iyi, yofunikira kwambiri yomwe ma relay amawonetsa kufunikira kwawo kwakukulu.
Kodi ma Relay mu Smart Meters ndi chiyani?
M'malo mwake, akutumizandi chosinthira chamagetsi. Imagwiritsa ntchito mphamvu yamagetsi yaying'ono kuwongolera mphamvu yayikulu kwambiri, kapena kusinthana pakati pa mabwalo osiyanasiyana. M'mamita anzeru, ma relay nthawi zambiri amakhalamaginito latching relay. Mosiyana ndi ma relay achikhalidwe omwe amafunikira mphamvu mosalekeza kuti asinthe mawonekedwe awo (kaya ON kapena WOZIMA), zolumikizira maginito zimakhala ndi mapangidwe apadera omwe amawalola kuti "atseke" pamalo ake atalandira kugunda kwamagetsi kwakanthawi. Izi zikutanthauza kuti amangogwiritsa ntchito mphamvu pakanthawi kochepa kosinthira, ndikuchepetsa kwambiri kugwiritsa ntchito magetsi oyimilira—chinthu chofunikira kwambiri pazida zonga ma smart metre zomwe zimayenera kugwira ntchito mosalekeza kwa zaka zambiri.
Zigawo zolimbazi zimaphatikizidwa mwachindunji mkati mwa mita yanzeru, zoyikidwa kuti zilumikize kapena kuletsa kutuluka kwa magetsi kumalo. Kampani ikafuna kulumikiza magetsi kwa kasitomala watsopano, kubwezeretsanso ntchito, kapena, nthawi zina, kuletsa ntchito (mwachitsanzo, chifukwa chosalipira kapena pakagwa mwadzidzidzi), imatumiza chizindikiro ku mita yanzeru. Zamagetsi zamkati zamamita zimatanthauzira chizindikiro ichi, ndipo, yambitsaninso njira yolumikizirana kuti musinthe chingwe chamagetsi. Kuvina kovutirako kwa ma sigino ndi machitidwe amakina amatsindikitsa ntchito ya relay ngati mawonekedwe owoneka bwino apakati pa malamulo a digito azomwe zimagwiritsidwa ntchito ndi kayendedwe ka magetsi.
Makhalidwe enieni a ma relay awa ndi ofunikira kuti agwire ntchito yodalirika ya mita yanzeru. Ayenera kukhala okhoza kunyamula katundu wamakono, nthawi zambiri kuyambira 60A mpaka 120A, ndipo ayenera kukhala ndi mphamvu zambiri za dielectric kuti azilekanitsa ma circuit. Kuphatikiza apo, kuthekera kwawo kupirira mafunde afupiafupi osawonongeka kapena kuchititsa ngozi kwambiri ndikofunikira kwambiri pakukhazikika kwa gridi ndi chitetezo. Mwachitsanzo, Malio amapereka ntchito zapamwambamaginito latching relay kwa anzeru mamita, kuphatikizapo mphamvu zawoMagnetic Latching Relay(P/N MLLR-2189). Chitsanzochi chimakhala ndi kusintha kwakukulu kwa 120A ndi luso lodabwitsa lotha kupirira nthawi yochepa kwambiri ya 3000A kwa 10ms popanda vuto, komanso ngakhale 6000A kwa 10ms popanda kulephera koopsa, kuwonetsa zofuna zazikulu zomwe zimayikidwa pazigawozi.
Kodi Ntchito ya Smart Relay ndi chiyani?
Chiwongolero chanzeru, kaya choyimira choyimira kapena chophatikizidwa, chitha kukhala ndi zinthu monga:
• Njira Zolumikizirana Zowonjezereka:Kupatula kungolandira lamulo losavuta la ON/OFF, cholumikizira chanzeru chimatha kufotokozera momwe chikugwirira ntchito, kutsimikizira kusintha kwabwino, kapena kufotokoza zambiri zokhudzana ndi thanzi lake. Kuyankhulana kwapawiri kumeneku kumasintha kusintha kwapang'onopang'ono kukhala wochita nawo mbali mu zokambirana za grid.
•Advanced logic ndi Programmability:Ma relay ena anzeru amakhala ndi ma microcontrollers amkati, omwe amalola kuti malingaliro ovuta apangidwe mwachindunji mu chipangizocho. Izi zitha kuloleza kusintha kotengera nthawi, kukhetsa katundu kutengera momwe zinthu ziliri pa gridi, kapena kutenga nawo gawo pamapulogalamu omwe amayankhidwa, pomwe katundu wosafunikira amachotsedwa kwakanthawi panthawi yomwe ikufunika kwambiri.
•Kuzindikira Zolakwa ndi Chitetezo:Njira yolumikizirana yanzeru imatha kupangidwa kuti izindikire zolakwika pamayendetsedwe amagetsi, monga ma overcurrents kapena ma frequency afupiafupi, ndikuyenda zokha kuti muteteze mita ndi zida zolumikizidwa. Ntchito yodzitchinjiriza iyi imapitilira kusintha kosavuta, ndikuwonjezera chitetezo ndi kudalirika.
•Mphamvu Zowunika Mphamvu:Ngakhale mita yanzeru payokha ndiye chipangizo choyambirira choyezera mphamvu, maulumikizidwe ena anzeru amatha kuphatikizira zomveka zamakono kapena zamagetsi kuti apereke chidziwitso cha komweko, kukulitsa kumvetsetsa kwa gululi pakugawa magetsi.
•Kuzindikira kwakutali ndi Kudzichiritsa Wekha:Ma relay apamwamba kwambiri anzeru amatha kudzifufuza okha, kuzindikira zolephera zomwe zingachitike, komanso kuyankhulana ndi zinthu zomwe zimathandizira, kumathandizira kukonza zolosera komanso kuchepetsa nthawi yopumira. Njira yolimbikitsira iyi yokonza ndi mwala wapangodya wa kasamalidwe ka grid mwanzeru.
Pankhani yamamita anzeru, pomwe maginito olumikizirana ndi otsogola, "nzeru" nthawi zambiri zimachokera kugawo lowongolera la mita lomwe limayang'anira machitidwe a relay kutengera ma siginecha omwe akubwera komanso malingaliro opangidwa. Relay imagwira ntchito ngati dzanja lamphamvu lamphamvu, kutsatira mokhulupirika malamulo operekedwa ndi luntha lophatikizika la mita. Malio athunthu osiyanasiyanamaulendozamamita anzeru ndi chitsanzo cha izi, kuchokera kumitundu yayikulu ya 120A kupita ku yosunthikaMaginito Latching Relays. Zipangizozi zidapangidwa kuti zizisintha bwino komanso kuti zikhale zolimba kwambiri, zimatha kupirira magetsi 100,000 ndikuwonetsa kukana kukhudzana kochepa (0.6mΩ), kuwonetsetsa kusuntha kwamphamvu kwamphamvu popanda kutayika kosayenera.
Kudalirika kwa ma relay awa ndikofunikira kwambiri. Kutumizirana zinthu molakwika kungayambitse kusokonezedwa kwa ntchito, kulipira ndalama molakwika, ngakhale ngozi zachitetezo. Chifukwa chake, opanga ngati Malio amagogomezera kuyezetsa kolimba komanso zida zapamwamba kwambiri, monga AgSnO2 pazolumikizana, zomwe zimatsimikizira kukana kutsika komanso moyo wautali wogwira ntchito. Zomwe zimafunikira, monga mphamvu ya dielectric yayikulu (AC4,000V pakati pa koyilo ndi zolumikizana) ndi kutentha kwakukulu kogwira ntchito (-40 ℃ mpaka +85 ℃), sizinthu zaukadaulo; ndizomwe zimafunikira pakuwonetsetsa kuti zida zosaonekazi zimagwira ntchito bwino kwa zaka zambiri m'malo osiyanasiyana komanso ovuta komwe makina anzeru amayikidwa.
M'malo mwake, ma relay ndi omwe amatsogolera mwamphamvu malamulo a digito a mita. Ndiwo minofu yosasunthika, yamakina kumbuyo kwa ubongo wa nzeru za grid. Popanda kuchitapo kanthu kodalirika, kusanthula kwatsatanetsatane kwa data ndi kuthekera kolumikizana kwamamita anzeru zikadakhalabe zongopeka. Pamene dziko likusintha kupita ku ma gridi anzeru, okhazikika, komanso okhazikika, ma gridi odzichepetsa koma amphamvu apitiliza kuchita gawo lofunika kwambiri, kuwonetsetsa kuti mphamvu zopanda malire komanso zanzeru zomwe zimalimbikitsa miyoyo yathu yolumikizana.
