Kusiyanisa kuchengetedza inzira yekuchengetedza mitsara yemagetsi. Chinosiyanisa feeder, kana iyo "dummy mutoro" sekudanwa kwayinowanzoitwa, ine imwe tambo yetambo inomhanya yakaenzana uye yakavakirwa pasi kuti ipe yakawedzerwa kuchengetedzeka kana chero chinhu chikakanganisika nerutivi rumwe rwemagetsi. Iyo Merz-Mutengo inotenderera yazvino system yakatanga kugadzirwa nevaviri veGerman vagadziri vakauya neiyi pfungwa ivo pavakange vachishanda kuNokia pamatambo epasi pegungwa!

Chii chinorehwa nekudzivirira kusiyanisa?
Kusiyanisa kuchengetedza ndeyeyuniti-mhando dziviriro kune chaiwo matunhu kana zvishandiso. Misiyano iripo pakati pekuisa uye kubuda mafashama inogona kungova yakakwira kana paine zvikanganiso zvemukati kune iyo zone, zvichireva kuti iwe unochengetedzwa kubva kumatyisidziro ekunze uko kunenge kusingave nemusiyano wakawanda nesimba rako richiuya mariri; izvi zvakare zvinoreva kuti kana chimwe chinhu chikatadza mukati mukati iwe waizoziva nekuti iyo alarm system inofanira kurira kamwechete!
Vafudzi vanodzivirirwa sei?
Vazhinji vanodyisa vanodzivirirwa kubva kumatunhu mapfupi. Mumamiriro ezvinhu apo magetsi anongo dimburwa kamwe kamwe, mudariki wedunhu padhuze naro anofanira kuvhura uye mamwe mabhureki anoramba akavharwa kuitira kuti magetsi mashoma ayerere kuburikidza neyakagara isina kugadzikana mamiriro kana paine kumwe kukanganisa kumwe kumutsara. Izvo zvakakosha kunyangwe kuti dziviriro iyi ichengetedzwe nevanopaza padhuze kana mumwe akakundikana- zvikasadaro panogona kunge paine zvimwe zvikanganiso zvichikonzera kudzima magetsi kana zvakatoipa zvakadaro, moto!
Kudzivirira kwekusiyanisa kunoshandiswa kupi?
Kusiyanisa kuchengetedza rudzi rwemasimba system kuputira iyo inodzivirira kubva kune chikamu-kune-chikamu kukanganisa uye chikamu kune zvikanganiso zvepasi. Mashanduri emagetsi anodzivirirwa neiyi nzira, iyo inomhanya pamisimboti yekutenderera zvazvino yakagadzirwa muna 1898 neMerz & Prize Kambani. Iyi nzira inopa imwe nhanho yekudzivirira yakakwira magetsi michina senge iwo akayerwa anopfuura anopfuura 2 MVA kugona kubva mukukuvadzwa nekuda kwemagetsi magetsi kana kusangana nevamwe vafambisi kana ichinge yatadza kushanda.
Ndeapi matambudziko ekusiyaniswa kwekudzivirira?
Kudzivirirwa kwakasiyana inyaya yakaoma, sezvo ichitarisa akasiyana misiyano. Semuenzaniso, zvisingaenzaniswi shanduko hunhu hunogona kukonzera mismatched CTs kuti ikurumidze nguva isati yakwana kana kwete zvachose; kubata dunhu kunokonzera kusaenzana kunogona kukonzera moto uye kuputika nekuda kwekuwedzera kwazvino kuyerera (magnetizing evashanduki). Iyo magnetizing inrush currents yakasangana panguva yekutanga inonetsawo kusiyanisa michina yekudzivirira kupindura nekukasira zvakakwana kana zvikaitika nekuti nguva dzekupindura dzinosiyana zvichienderana nekukurumidza kwavanoona shanduko mukati mechirongwa. Kudzivirirwa kwakasiyana kwave kuriko kwechinguva uye kuchiri imwe yedzedu nzira dzakasimba kwazvo dzekuchengetedza pamatambudziko pasystem pasina kukanganisa masimba emagetsi akadai semagetsi anodzika.
Ndeupi musiyano uripakati pekurambidzwa kwepasi kukanganisa uye kusiyanisa dziviriro?
Musiyano uripakati pekurambidzwa kwepasi kukanganisa uye kusiyanisa dziviriro ndeyekuti munhu anoona zvikanganiso mukati meTransformer pamativi ese ekutanga uye echipiri, nepo mumwe wacho achingoona zvikanganiso zvepasi munzvimbo kubva kuSecond winding kuenda kuSecond CTs.
Chii chinonzi muzana kusiyanisa kuchengetedza?
Iyo yekusiyanisa kusiyanisa dziviriro ndeye relay iyo inochengetedza iyo system nekushanda pamwe chidimbu hukama hwezvino. Iyo yazvino transformer saturation, isina kuenzana CT ratios uye nhamo nzendo zvese zvingangoita matambudziko kune wemagetsi kudzivirira kubva pakuisa kana kuchengetedza masystem emagetsi.
Ndeipi nhungamiro yekusiyanisa dziviriro yakavakirwa?
Kusiyanisa kuchengetedza kunoenderana nesisitimu yekuenzanisa maviri kana anopfuura emagetsi akawanda. Semuenzaniso, iyo relay ine mashandiro ayo anoenderana nechikamu musiyano uye hukuru hwaizokwanisa kuenzanisa hunhu uhwu kuti vaone chero njodzi dzinogona kuitika vasati vawana mukana wekuita.
