Mu rwego rwubwubatsi bwamashanyarazi, akamaro ko gupimwa neza ntigushobora kuvugwa. Kimwe mu bintu by'ingenzi byorohereza ibipimo bigezweho ni transformateur y'ubu (CT). Iyi ngingo iracengera mubikorwa byimpinduka zubu mugupima porogaramu, ziga impamvu zikoreshwa nubwoko bwa transformateur busanzwe bukoreshwa kubwiyi ntego.
Niki Guhindura Niki?
A impindukani ubwoko bwa transformateur yagenewe kubyara umusaruro usohoka ugereranije numuyoboro utemba mukuzunguruka kwambere. Ibi bituma ibipimo byizewe byumuyaga mwinshi ubihindura murwego rwo hasi, rushobora gucungwa rushobora gupimwa byoroshye nibikoresho bisanzwe bipima. Impinduka zubu zikoreshwa cyane mubikorwa bitandukanye, harimo kubyara amashanyarazi, guhererekanya, no gukwirakwiza sisitemu.
Ni ukubera iki Impinduka zubu zikoreshwa mugupima?
1. Umutekano
Imwe mumpamvu zambere zo gukoresha impinduka zubu mugupima porogaramu ni umutekano. Umuvuduko mwinshi hamwe nubu urwego rushobora guteza ingaruka zikomeye kubakozi nibikoresho. Ukoresheje transformateur ya none, umuyoboro muremure uhindurwa murwego rwo hasi, rutekanye rushobora gukemurwa nibikoresho bisanzwe byo gupima. Ibi byemeza ko abatekinisiye bashobora gukurikirana neza no gucunga sisitemu y'amashanyarazi nta kibazo cyo guhungabana kw'amashanyarazi cyangwa ibikoresho byangiritse.
2. Ukuri
Impinduka zubu zagenewe gutanga ibipimo nyabyo byubu. Bahinduwe kugirango barebe ko ibyasohotse ari igice cyuzuye cyinjiza. Uku kuri ni ingenzi mu gupima porogaramu, aho ndetse no kunyuranya bito bishobora gutera igihombo gikomeye cyamafaranga cyangwa imikorere idahwitse. Ukoresheje transformateur igezweho, ibikorwa byubucuruzi nubucuruzi birashobora kwemeza ko sisitemu zabo zipima zitanga amakuru yizewe yo kwishura no gufata ibyemezo.
3. Kwigunga
Impinduka zubu nazo zitanga amashanyarazi hagati ya sisitemu yo hejuru ya voltage nibikoresho byo gupima. Uku kwigunga ni ngombwa mu kurinda ibikoresho byoroshye biturutse ku muvuduko wa voltage n’indi mvururu z’amashanyarazi. Mugutandukanya ibikoresho bipima mumashanyarazi yumuriro mwinshi, impinduka zubu zifasha kuzamura kuramba no kwizerwa bya sisitemu yo gupima.
4. Ubunini
Impinduka zubu zirashobora kuba nini cyane, bigatuma zikoreshwa muburyo butandukanye bwa porogaramu. Haba gupima ikigezweho muri sisitemu ntoya yo guturamo cyangwa inganda nini nini, inganda zigezweho zirashobora gushushanywa kugirango zikore urwego rutandukanye. Ubu buryo bwinshi butuma habaho kwinjiza byoroshye muri sisitemu zihari, bigatuma bahitamo gukundwa no gupima porogaramu mu nzego zitandukanye.
5. Ikiguzi-Cyiza
Gukoreshaimpinduka zubukubipima birashobora kuba igisubizo cyigiciro. Muguha uburenganzira bwo gupima imigezi miremire bidakenewe ibikoresho bihenze-bigezweho byo gupima, impinduka zubu zigabanya igiciro rusange cya sisitemu yo gupima. Byongeye kandi, kuramba kwabo no kwizerwa bivuze ko bisaba gusimburwa kenshi, bikagira uruhare mukuzigama amafaranga mugihe.
Niki Transformer ikoreshwa mugupima?
Mugihe impinduka zubu nubwoko busanzwe bwa transformateur ikoreshwa mugupima, hari ubundi bwoko bushobora no gukoreshwa bitewe nibisabwa byihariye bya porogaramu.
1. Abashobora Guhindura (PTs)
Usibye impinduka zubu, impinduka zishobora gukoreshwa (PTs) zikoreshwa kenshi mugupima porogaramu. PTs zagenewe kumanura voltage ndende kugirango igabanuke, urwego rushobora gupimwa. Mugihe impinduka zubu zibanda ku gupima ibyagezweho, impinduka zishobora kuba ngombwa mugupima voltage. Hamwe na hamwe, CT na PTs bitanga igisubizo cyuzuye cyo gupima sisitemu y'amashanyarazi.
2. Guhindura ibikoresho byahujwe
Rimwe na rimwe, ibyuma bihuza ibikoresho bihuza byombi nibishobora guhinduka mubice bimwe bikoreshwa. Ibi bikoresho byoroshya kwishyiriraho no kugabanya umwanya ukenewe kubikoresho bipima. Zifite akamaro cyane mubisabwa aho umwanya ari muto cyangwa aho icyifuzo cyo gupima cyoroshye.
3. Impinduka zubwenge
Hamwe nogukoresha tekinoroji ya gride yubuhanga, impinduka zubwenge ziragenda zamamara mugupima porogaramu. Izi mpinduka ntizipima gusa na voltage gusa ahubwo inatanga amakuru nyayo yisesengura nubushobozi bwitumanaho. Ibi bituma ibikorwa byingirakamaro bikurikirana sisitemu zabo neza kandi bigafata ibyemezo bishingiye kumibare kugirango byongere imikorere kandi yizewe.
Umwanzuro
Impinduka zubuGira uruhare runini mugupima porogaramu, gutanga umutekano, ubunyangamugayo, kwigunga, ubunini, hamwe nigiciro-cyiza. Ubushobozi bwabo bwo guhindura imigezi miremire murwego rushobora gucungwa bituma iba ingenzi muri sisitemu zitandukanye zamashanyarazi. Mugihe impinduka zubu arizo guhitamo kwambere kubipimo bigezweho, ibishobora guhinduka hamwe nibikoresho bihinduranya nabyo bigira uruhare mubisubizo byuzuye. Mugihe ikoranabuhanga rikomeje gutera imbere, kwishyira hamwe kwihinduramatwara byubwenge bizarushaho kongera ubushobozi bwa sisitemu yo gupima, bigatanga inzira kumashanyarazi meza kandi yizewe. Gusobanukirwa n'akamaro ko guhindura ibintu muri iki gihe ni ngombwa kuri buri wese ugira uruhare mu nganda z'amashanyarazi, kuko ari urufunguzo rwo gupima neza kandi neza ibipimo by'amashanyarazi.
