Muri orchestre nini ya gride yingufu zigezweho,metero y'ubwengeuhagarare nkibikoresho byingenzi, uhuza inzira hagati yingufu za gakondo, zidafite icyerekezo hamwe ningufu zingirakamaro, zikorana. Aho kuba gusa imibare ihwanye na analogi yababanjirije, ibyo bikoresho bihanitse ni ingingo zifatika zamakuru, itumanaho, no kugenzura. Intandaro yimikorere yabo ikora, ikora nkicecekeye, nyamara ntigisabwa, abakemurampaka bayobora ingufu, nirelay. Izi mashanyarazi cyangwa zikomeye-zihinduranya ni sentinel zitavuzwe ziha imbaraga za metero zubwenge nibikorwa byazo bikomeye: kugenzura kure kubitanga amashanyarazi.
Kuza kwa metero zubwenge zitangaza ibihe bihinduka kubakoresha ndetse nabaguzi kimwe. Intego yabo yibanze irenze kure gupima ibyo ukoresha. A.intego yibanze ya meteroni ugutanga igihe-nyacyo cyangwa hafi yigihe-nyacyo cyo gukoresha ingufu kubitanga byingirakamaro hamwe nuwanyuma-ukoresha. Ubu bushobozi bwo gutumanaho bwibice bibiri butuma ibikorwa byinshi bigezweho: gusoma metero ya kure, bikuraho gukenera gusurwa nintoki; isesengura rirambuye ryabakoresha kugirango bongere imikoreshereze yabo; kandi, cyane cyane, ubushobozi bwibikorwa byo gucunga kure amashanyarazi. Nibikorwa byanyuma, ibikorwa byingenzi byerekana akamaro kabo.
Ni ubuhe butumwa bukoreshwa mu bipimo byubwenge?
Muri rusange, arelayni amashanyarazi akoreshwa. Ikoresha amashanyarazi ntoya ugereranije no kugenzura imiyoboro minini cyane, cyangwa guhinduranya imirongo itandukanye. Muri metero zubwenge, ibyerekanwa mubisanzwerukuruzi ya rukuruzi. Bitandukanye na gakondo gakondo isaba imbaraga zihoraho kugirango zigumane imiterere yazo (haba kuri ON cyangwa OFF), ibyuma bifata ibyuma bya magnetiki bifite igishushanyo cyihariye kibemerera "gufunga" mumwanya nyuma yo kubona amashanyarazi make. Ibi bivuze ko bakoresha imbaraga gusa mugihe gito cyo guhinduranya, bikagabanya cyane gukoresha ingufu zihagaze - ikintu cyingenzi kubikoresho nka metero zifite ubwenge zigomba gukora ubudahwema imyaka.
Ibi bikoresho bikomeye byinjijwe neza muri metero yubwenge, bihagaze kugirango bihuze cyangwa bihagarike umuvuduko wamashanyarazi ahantu. Iyo akamaro gakeneye guhuza imbaraga kubakiriya bashya, kugarura serivisi, cyangwa, mubihe bimwe na bimwe, guhagarika serivisi (urugero, kubwo kutishyura cyangwa mugihe cyihutirwa), yohereza ikimenyetso kuri metero yubwenge. Imashini yimbere ya metero isobanura iki kimenyetso, hanyuma, igakora relay ihuriweho kugirango uhindure umurongo w'amashanyarazi. Iyi mbyino itoroshye yibimenyetso nibikorwa byubukanishi bishimangira uruhare rwa relay nkimiterere yumubiri hagati yamabwiriza ya digitale yingirakamaro hamwe ningufu zifatika zamashanyarazi.
Ibiranga ibintu byihariye biranga ingirakamaro kubikorwa bya metero byizewe byizewe. Bagomba kuba bafite ubushobozi bwo gutwara imizigo ihambaye, akenshi kuva kuri 60A kugeza 120A, kandi bagomba kugira imbaraga nyinshi za dielectric kugirango batandukane neza. Byongeye kandi, ubushobozi bwabo bwo guhangana ningaruka zumuzunguruko utarinze kwangirika cyangwa gutera gutsindwa kwibyingenzi nibyingenzi mumashanyarazi n'umutekano. Malio, kurugero, itanga imikorere-yo hejururukuruzi ya magnetiki yerekana metero zubwenge, harimo imbaraga zaboImiyoboro ya Magnetiki(P / N MLLR-2189). Iyi moderi yihariye ifite icyerekezo kinini cyo guhinduranya cya 120A hamwe nubushobozi budasanzwe bwo kwihanganira umuyoboro mugari ntarengwa wa 3000A kuri 10m utagira imikorere, ndetse na 6000A kuri 10ms nta gutsindwa gukabije, byerekana ibyifuzo bikomeye byashyizwe kuri ibyo bice.
Ni ubuhe butumwa bwa relay yubwenge?
Icyerekezo cyubwenge, cyaba igice cyihariye cyangwa igice cyashyizwemo, gishobora kubamo ibintu nka:
• Kunoza protocole y'itumanaho:Usibye kwakira gusa itegeko ryoroheje ON / OFF, relay yubwenge irashobora kumenyekanisha imiterere yayo mugikorwa, kwemeza ibikorwa byoguhindura neza, cyangwa no gutanga amakuru yo kwisuzumisha kubyerekeye ubuzima bwayo. Iri tumanaho ryerekezo rihindura uburyo bworoshye bwo kwitabira ibikorwa bya gride.
•Iterambere ryumvikana hamwe na Programmability:Bimwe mubikoresho byubwenge bifite microcontrollers imbere, byemerera logique igoye gutegurwa mubikoresho. Ibi birashobora gutuma igihe gishingiye ku guhinduranya, gusuka imitwaro ukurikije imiterere ya gride, cyangwa no kwitabira gahunda-isubiza ibyifuzo, aho imizigo itari ngombwa ihagarikwa byigihe gito mugihe cyibisabwa.
•Kumenya no Kurinda Amakosa:Icyerekezo cyubwenge gishobora gutegurwa kugirango hamenyekane ibintu bidasanzwe mumashanyarazi, nkibirenga cyangwa imiyoboro migufi, nurugendo rwihuse kugirango urinde metero nibikoresho bihujwe. Iyi mikorere irinda ibikorwa birenze guhinduranya byoroshye, wongeyeho urwego rwumutekano no kwizerwa.
•Ubushobozi bwo gukurikirana ingufu:Mugihe metero yubwenge ubwayo nigikoresho cyambere cyo gupima ingufu, ibyuma bimwe byubwenge bishobora guhuza imiyoboro ya rudimentary cyangwa voltage sensing kugirango itange amakuru yaho, bikarushaho gushimangira imyumvire ya gride yo gukwirakwiza amashanyarazi.
•Kwipimisha kure no kwikiza:Iterambere ryubwenge ryambere rirashobora gukora kwisuzumisha, kumenya ibishobora kunanirwa, ndetse no kugeza ibyo bibazo mubikorwa byingirakamaro, byoroshya kubungabunga no kugabanya igihe cyo gutaha. Ubu buryo bufatika bwo kubungabunga ni urufatiro rwo gucunga neza ubwenge.
Mu rwego rwa metero zubwenge, mugihe ibyuma bifata ibyuma bya magnetiki ubwabyo bifite ubuhanga, "ubwenge" akenshi buturuka kubice bishinzwe kugenzura metero itegura imyitwarire ya relay ishingiye kubimenyetso byinjira hamwe na logique ya programme. Ikirangantego gikora nk'ubuyobozi bukomeye, bushyira mu bikorwa mu budahemuka amategeko yatanzwe na metero ihuriweho n'ubwenge. Malio yuzuyerelaykuri metero zubwenge zirerekana ibi, uhereye kubushobozi buke 120A butandukanye kugeza kuri byinshiImiyoboro ya Magnetiki. Ibi bikoresho byashizweho kugirango bihindurwe neza kandi biramba bidasanzwe, birashobora kwihanganira ibikorwa byamashanyarazi 100.000 no kwerekana imbaraga nkeya (0.6mΩ), bigatuma ihererekanyabubasha ryiza nta gihombo gikabije.
Ubwizerwe bwibi bisobanuro nibyingenzi. Kwerekana nabi birashobora gutuma serivisi zihagarara, fagitire idahwitse, cyangwa n’umutekano muke. Kubwibyo, abakora nka Malio bashimangira igeragezwa rikomeye nibikoresho byujuje ubuziranenge, nka AgSnO2 kubitumanaho, ibyo bigatuma abantu badahangana kandi bakabaho igihe kirekire. Ibisobanuro bisabwa, nkimbaraga za dielectric (AC4,000V hagati ya coil na contact) hamwe nubushyuhe bwagutse bwo gukora (-40 ℃ kugeza + 85 ℃), ntabwo ari tekiniki gusa; nibisabwa shingiro kugirango tumenye neza ko ibice bitagaragara bikora neza mumyaka myinshi mubihe bitandukanye kandi bikunze kugora aho metero zubwenge zikoreshwa.
Mubyukuri, relay ni imbaraga zikomeye, zikora muburyo bwa metero yubwenge ya sisitemu ya digitale. Nimitsi idacurangwa, yimashini inyuma yubwonko bwubwenge bwa grid. Hatariho ibikorwa byabo byiringirwa, isesengura ryamakuru yisesengura hamwe nubushobozi bwitumanaho rya metero zubwenge byakomeza kuba theoretical. Mugihe isi igenda igana ubwenge bwimbitse, burambye, kandi bukomeye, imiyoboro yoroheje ariko ikomeye izakomeza kugira uruhare rukomeye, itume imbaraga zidafite imbaraga kandi zubwenge zituma ubuzima bwacu bufitanye isano.
