Mubihe byikoranabuhanga rya digitale, metero zubwenge zagaragaye nkigikoresho cyimpinduramatwara yo gucunga ingufu. Ibi bikoresho ntabwo bipima gukoresha ingufu gusa ahubwo binatanga amakuru yigihe-gihe kubakoresha ndetse namasosiyete yingirakamaro. Gusobanukirwa ibice bya metero yubwenge nibyingenzi mugusobanukirwa uko bikora nibyiza batanga. Imetero yubwenge igizwe ahanini nibice bitatu: guhinduranya, gupima, no guterana. Muri ibyo byiciro, ibice byinshi byingenzi bigira uruhare runini, harimo na Magnetic Latching Relay, Transformer ya none, na manganin shunt.
1. Guhindura: Imiyoboro ya Magnetique
Ku mutima wa metero yubwenge ikora ni switch, ikunze koroherezwa na aImiyoboro ya Magnetiki(MLR). Ibi bice nibyingenzi mugucunga amashanyarazi kugera no kuva kuri metero. Bitandukanye na relaire gakondo, bisaba imbaraga zihoraho kugirango zigumane imiterere yazo, ibyuma bifata magnetiki bifashisha umurima wa magneti kugirango ufate umwanya wabo. Iyi mikorere ibemerera gukoresha ingufu nke, bigatuma bahitamo neza kuri metero zubwenge.
MLR irashobora guhinduranya hagati yigihugu no kuzimya bidakeneye guhora amashanyarazi, bifasha cyane cyane ingufu zingirakamaro. Ubu bushobozi ntibugabanya gusa ingufu zikoreshwa muri metero yubwenge ahubwo binongera ubwizerwe. Mugihe habaye umuriro w'amashanyarazi, MLR irashobora gukomeza uko imeze, ikemeza ko metero ikomeza gukora neza iyo ingufu zimaze kugaruka.
2. Igipimo: Transformer y'ubu na Manganin Shunt
Ibipimo byo gupima metero yubwenge nibyingenzi mugupima neza gukoresha ingufu. Ibintu bibiri byibanze bigira uruhare muriki gikorwa ni Transformer ya none (CT) na manganin shunt.
Impinduka zubu(CT)
Impinduka zubu ni ikintu cyingenzi cyemerera metero yubwenge gupima umuyaga unyura mumashanyarazi. Ikora ku ihame rya induction ya electromagnetic, aho umuyoboro wibanze ubyara umurima wa rukuruzi utera umuyagankuba ugereranije no guhinduranya kwa kabiri kwa transformateur. Ihinduka ryemerera gupima neza kandi neza kwimyuka miremire bidakenewe guhuza amashanyarazi.
CT ifite akamaro kanini muri metero zubwenge kuko zishobora gutanga amakuru nyayo kubijyanye no gukoresha ingufu, bigafasha abakoresha gukurikirana imikoreshereze yabo. Aya makuru arashobora kuba ingirakamaro kubakoresha ndetse n’amasosiyete yingirakamaro, kuko yemerera gucunga neza ingufu no guteganya.
Manganin Shunt
Ikindi kintu gikomeye cyo gupima nimanganin shunt. Iki gikoresho gikoreshwa mugupima voltage igabanuka kurugero ruzwi, rwemerera metero yubwenge kubara ikigezweho kinyura mumuzunguruko. Manganin, umusemburo wumuringa, manganese, na nikel, watoranijwe kubera ubushyuhe buke bwo kurwanya ubukana, ibyo bikaba byerekana neza neza ibipimo.
Manganin shunt ifite akamaro kanini muri metero zubwenge kuko irashobora gukoresha imigezi myinshi mugihe ikomeza ituze kandi neza. Uku kuri ni ngombwa mu guha abakiriya amakuru yizewe ku mikoreshereze y’ingufu zabo, zishobora gutuma hafatwa ibyemezo byinshi bijyanye no gukoresha ingufu no kuzigama amafaranga.
3. Inteko: Guhuza Ibigize
Iteraniro rya metero yubwenge ikubiyemo guhuza ibintu, ibipimo byo gupima, hamwe nizindi zunguruka zorohereza itumanaho no gutunganya amakuru. Iyi nteko yateguwe kugirango ibice byose bikore hamwe kugirango bitange amakuru yukuri kandi mugihe.
Kwishyira hamwe kwibi bice bituma metero zubwenge zishobora kuvugana namasosiyete yingirakamaro binyuze mumiyoboro idafite umugozi. Ubu bushobozi bwitumanaho niterambere ryibanze kuri metero gakondo, bisaba gusoma intoki. Hamwe na metero zubwenge, amakuru arashobora koherezwa mugihe nyacyo, bigafasha ibikorwa bikurikirana uburyo bwo gukoresha ingufu, kumenya ibura, no gucunga umutungo neza.
Byongeye kandi, guteranya metero zubwenge akenshi bikubiyemo ibintu byateye imbere nka tamper detection, iburira ibigo byingirakamaro kuburiganya cyangwa gukoresha uruhushya. Uru rwego rwongeyeho umutekano ni ngombwa mu gukomeza ubusugire bwa sisitemu yo gukwirakwiza ingufu.
Umwanzuro
Muncamake, metero yubwenge igizwe nibice bitatu byingenzi: guhinduranya, gupima, no guterana. Magnetic Latching Relay ikora nka switch, itanga igenzura ryiza ryingufu. Ibipimo byo gupima, harimo na Transformer ya none na manganin shunt, byemeza neza neza imikoreshereze yingufu. Hanyuma, inteko ihuza ibyo bice, ituma itumanaho no gutunganya amakuru byongera imicungire yingufu.
Mugihe isi igenda igana kubikorwa byingufu zirambye, metero zubwenge zizagira uruhare runini mugufasha abakiriya n’amasosiyete yingirakamaro gukoresha neza ingufu. Gusobanukirwa ibice bigize ibyo bikoresho ningirakamaro mugushimira ingaruka zabyo mubikorwa byingufu no gucunga. Hamwe niterambere mu ikoranabuhanga, ejo hazaza ha metero zubwenge zirasa nicyizere, zitanga inzira kubisubizo byimbaraga zubwenge.
