PT na CT muri Transformers: Intwari zitavugwa z'amashanyarazi n'amashanyarazi

PT na CT muri Transformers: Intwari zitavugwa z'amashanyarazi n'amashanyarazi

Ku bijyanye na transfomasiyo,PT(Transformer ishobora kubaho) naCT(Current Transformer) bameze nk'itsinda ry'amashanyarazi rikoresha imbaraga ebyiri—Batman na Robin. Bashobora kuba badakoresha urumuri nk'urwo muri transformer ubwayo, ariko aba bombi bakora inyuma y'ibyiciro kugira ngo byose bigende neza kandi mu mutekano. Reka turebe uburyo bakora ibintu bitandukanye mu buryo butandukanye bwa transformer.

PT: Umuvuduko w'amashanyarazi

ItsindaTransformer ishobora kubaho (PT)niwe muntu ukunda kugabanya voltage nyinshi ukagera ku rwego rushoboka. Tekereza urimo guhangana n'ingufu nini cyane ya 33 kV (cyangwa irengaho) mu buryo bwawe bw'amashanyarazi—ni ikintu giteje akaga kandi ntabwo ari ikintu wifuza gupima mu buryo butaziguye. Aho niho PT igaragara. Ihindura iyo voltage itera umusatsi mo ikintu metero na relays zawe zishobora gukora zidaca ibyuya, akenshi ikamanuka ikagera kuri 110 V cyangwa 120 V.

None se, ni hehe ubona PT zikora?

• Transformateur zikoresha ingufu nyinshi: Izi ni imbunda nini z’umuyoboro w’amashanyarazi, zikoresha voltage kuva kuri 110 kV kugeza kuri 765 kV. PT hano zemeza ko ushobora kugenzura no gupima voltage mu mutekano uri kure.
• Transformateur za sitasiyo: PT zikora muri sitasiyo nto kugira ngo zigenzure kandi zigenzure urugero rw'amashanyarazi mbere yuko akwirakwizwa ku baguzi b'inganda cyangwa abaguzi bo mu ngo.
• Transfoma zo kurinda no gupima: Muri sisitemu aho kugenzura amashanyarazi ari ingenzi mu mutekano no kwishyuza, PT zitabira gutanga imiterere nyayo y'amashanyarazi ku byumba byo kugenzura, relays, n'ibikoresho byo kurinda.

PT ni nk'umusemuzi utuje kandi uhuze mu gitaramo cy'amashanyarazi, afata ayo matwi ya kV 110 agahindura ijwi ryoroheje ibikoresho byawe bishobora gukoresha.

CT: Umuhanga mu by'ubu

Noneho, reka tuvuge kuriTransformer y'ubu (CT), umutoza bwite wa sisitemu y'amashanyarazi. Iyo umuriro utangiye kogosha imitsi yawo hamwe na ampeta ibihumbi zinyura muri transformer yawe, CT irawugabanya kugeza ku rwego rwiza—ubusanzwe mu ntera ya 5 A cyangwa 1 A.

Uzasanga CTs zikora akazi ko gushakisha amakuru:

• Transformateur yo gukwirakwizas: Aba bantu bakorera mu duce dutuwemo cyangwa mu bucuruzi, akenshi bakora ku muvuduko wa volteji nka 11 kV kugeza 33 kV. CTs hano zigenzura kandi zirinda ubushyuhe, zigakurikirana ingano y'umutobe unyura mu miyoboro.
• Transformateur z'ingufu mu masiteshoni: CT zigenzura umuyoboro w'amashanyarazi ku mashanyarazi ari hejuru aho transfoma zigabanya umuyoboro w'amashanyarazi kuva ku rugero rwo kohereza (urugero, 132 kV cyangwa hejuru) kugera ku rugero rwo gukwirakwiza. Ni ingenzi cyane mu kumenya amakosa no gukumira ibikoresho byo kurinda mbere yuko hagira ikintu kigenda nabi.
• Transformateur z'inganda: Mu nganda cyangwa mu duce tw’inganda ziremereye, transformateur zikunze gutwara imizigo minini, kandi CT ziba zihari kugira ngo zigenzure imigezi minini. Iyo hari ikintu kitagenze neza, CT yohereza amakuru kuri sisitemu zo kurinda ibintu zigafunga mbere yuko ibikoresho bikarangwa.

Tekereza kuri CT nk'umurinzi mu kabyiniro—irinda umuriro kugira ngo udahungabanya uburyo bwawe bwo kurinda, kandi iyo ibintu birushijeho kuba bibi, CT igenzura ko umuntu ahagaze mu kaga.

Impamvu PT na CT ari ingenzi

Hamwe, PT na CT bigize itsinda ry’abapolisi b’inshuti nziza ku isi ya transformer. Niyo mpamvu abakoresha bashobora kugenzura no kugenzura imikorere ya transformer mu mutekano batiriwe begera inyamaswa (ndakwizeye, ntushaka kwegera ubwo bwoko bw’amashanyarazi n’umuyoboro w’amashanyarazi nta burinzi bukomeye). Byaba aritransformateur ikwirakwizamu gace utuyemo cyangwa mu gacetransformateur y'ingufu zifite ingufu nyinshiIngufu zitanga umuriro mu mijyi yose, PT na CT zihora zihari, bigatuma ingufu n'amashanyarazi biguma ku murongo.

Ikintu gishimishije: Gukomeza kureba impande zombi

Ese wigeze wibaza impamvu fagitire yawe y'amashanyarazi ari nziza cyane? Ushobora gushimira CT na PT muritransfoma zipima. Bagenzura neza ko ikigo cy’amashanyarazi n’umukiriya bazi neza ingano y’amashanyarazi akoreshwa binyuze mu kumanuka neza no gupima ingufu z’amashanyarazi n’amashanyarazi. Rero, yego, PT na CT bikomeza gukora ibintu neza kandi bigororotse ku mpera zombi z’umuyoboro w’amashanyarazi.

Umwanzuro

Rero, yaba ari transformateur ndende cyane cyangwa transformateur ikora cyane,PT na CTni intwari zitavugwa zituma ibintu byose bigenda neza. Zicunga ingufu nyinshi z'amashanyarazi n'imigezi minini kugira ngo abakoresha, abajyana, n'ibipimo bibashe kubitwara nta mwambaro w'intwari. Ubutaha ugiye gufungura itara, ibuka ko hari itsinda ry'abashinzwe kurinda amashanyarazi bakora ibishoboka byose kugira ngo ingufu n'amashanyarazi bikore neza.
