Amacandelo eTransformer acacisiwe

Ngokuqinisekileyo, ndingakunceda ngaloo nto. Nali inqaku elenziwe ngokungacwangciswanga ngokweemfuno zakho:

Amacandelo eTransformer acacisiwe

Abaguquli zizinto ezibalulekileyo kwiinkqubo zombane, ezinceda ukuhambisa nokusasaza amandla ngokufanelekileyo. Ukuqonda amacandelo ahlukeneyo e-transformer kubalulekile ekusebenzeni kwayo ngokufanelekileyo. Kule nqaku, siza kuhlolisisa amacandelo aphambili e-transformer kunye neendima zabo ekuququzeleleni ukuhanjiswa kwamandla ombane.

IiWindings zasePrayimari kunye nezeSekondari

I-windings ephambili kunye neyesibini zizinto eziphambili ze-transformer. I-primary winding yi-input side ye-transformer, apho amandla ombane anikezelwa ekuqaleni. Iqukethe uluhlu lweekhoyili ezinxeba malunga nombindi we-transformer. Umoya wesibini, ngakolunye uhlangothi, licala lokuphuma kwe-transformer, apho amandla ombane aguqulwayo ahanjiswa. Njengokujija okuphambili, ukujija okwesibini kukwabandakanya iseti yeekhoyili ezinxeba kumbindi. Inani lokujika kwi-windings ephambili kunye neyesibini inquma umlinganiselo we-voltage phakathi kwegalelo kunye nemveliso yamacala e-transformer.

Ii-windings eziphambili kunye nezesekondari zidlala indima ebalulekileyo ekuguquleni amandla ombane. Xa umsinga otshintshanayo udlula kwi-winging ephambili, ibangela intsimi yamagnetic eyohlukeneyo kumbindi we-transformer. Lo mmandla wemagnethi wahlukileyo, uvelisa amandla e-electromotive kwi-winding yesibini, ekhokelela ekuguqulweni kwamandla ombane kunye nangoku.

Undoqo weTransformer

Ingundoqo ye-transformer yenye into ebalulekileyo eyenza ukuhanjiswa kwamandla ombane. Ngokuqhelekileyo yenziwe ngezinto ze-ferromagnetic ezifana nentsimbi okanye intsimbi, ezinokungena kwimagnethi ephezulu. Undoqo ubonelela ngomendo ophantsi wobunxaxha wokuqukuqela kazibuthe oveliswe ngumjikelo ophambili, ovumela ukuhanjiswa okusebenzayo kwamandla ukuya kumoya wesibini.

Uyilo kunye nokwakhiwa kwe-transformer core kubalulekile ekunciphiseni ilahleko yamandla kunye nokwandisa ukusebenza kakuhle. Iicores zihlala zakhiwe ngamashiti alaminated we-ferromagnetic material ukunciphisa imisinga yeeddy kunye nelahleko yehysteresis. Oku kuqinisekisa ukuba i-transformer isebenza ngokufanelekileyo, ukunciphisa ukuchithwa kwamandla kunye nokuveliswa kobushushu.

Izinto zokugquma

Izinto zokukhusela zisetyenziselwa ukwahlula kunye nokukhusela amacandelo ahlukeneyo e-transformer, njenge-windings kunye nengundoqo. Ezi zinto ziyimfuneko ekukhuseleni ukuvuza kombane kunye nokuqinisekisa ukusebenza okukhuselekileyo kwe-transformer. Izinto eziqhelekileyo zokukhusela ezisetyenziswa kwii-transformers ziquka iphepha, ikotoni, kunye nezinto ezahlukeneyo zokwenziwa ezinikezela amandla aphezulu e-dielectric kunye nokuzinza kwe-thermal.

Ukukhethwa kwezinto zokukhusela i-insulating kubaluleke kakhulu ekunqumeni ukusebenza ngokubanzi kunye nobude obude be-transformer. I-insulation ephezulu esemgangathweni inceda ukunciphisa umngcipheko wokuqhekeka kombane kwaye iqinisekisa ukusebenza okuthembekileyo kwe-transformer ngexesha lokuphila kwayo. Ukongezelela, ukunyuswa okufanelekileyo kunciphisa amathuba okuba neesekethe ezimfutshane kunye nezinye iimpazamo zombane, ukuphucula ukhuseleko kunye nokusebenza kakuhle kwe-transformer.

Cofa Guqula

Umtshintshi wempompo yinto efunyenwe kwiinguqu ezininzi ezivumela ukulungiswa komlinganiselo wokujika kwe-transformer. Oku kwenza ukuba umlinganiselo wombane phakathi kwe-windings ephambili kunye neyesibini iguqulwe, inikezela ukuguquguquka ekutshintsheni utshintsho kwinethiwekhi yombane. Iziguquli zempompo zisetyenziswa ngokuqhelekileyo kwiiguquli zokusasaza amandla okulawula imveliso yombane ekuphenduleni iimeko zomthwalo ohlukeneyo.

Kukho iindidi ezimbini eziphambili zokutshintsha impompo: abaguquli betephu ekulayishweni (OLTC) kunye nabatshintshi betephu ephuma kwisekethe (OCTC). Ii-OLTC zivumela uhlengahlengiso ukuba lwenziwe ngelixa i-transformer inamandla, ivumela utshintsho olungenamthungo kwimveliso yombane ngaphandle kokuphazamisa ukunikezelwa kwamandla. Ii-OCTC, ngakolunye uhlangothi, zifuna ukuba i-transformer ikhutshwe amandla ngexesha lenkqubo yokucofa. Uhlobo lwempompo yokutshintsha esetyenzisiweyo luxhomekeke kwiimfuno ezithile zenethiwekhi yombane kunye nesicelo somguquli.

Buchholz Relay

I-Buchholz relay sisixhobo esikhuselayo esihlala sifakwe kwii-transformers ezizaliswe ngeoli ukuze zibone kwaye ziphendule kwiimpazamo zangaphakathi. Isebenza ngokubeka esweni ukuhamba kweoli ngaphakathi kwe-transformer kunye nokufumanisa iimeko ezingaqhelekanga ezifana nobukho begesi okanye utshintsho olukhawulezayo loxinzelelo. Xa oko kungaqhelekanga kufunyenwe, i-relay iqalisa umqondiso wohambo ukukhupha i-transformer kuthungelwano lombane, ukuthintela umonakalo ongaphezulu kunye nokuqinisekisa ukhuseleko lwenkqubo.

I-Buchholz relay yinto ebalulekileyo yokhuseleko kwi-oyile ye-oyile yokuguqula i-oyile, ibonelele ukubonwa kwangaphambili kweempazamo ezinokubakho kunye nokunceda ukuthintela ukusilela okuyintlekele. Ikhono layo lokuphendula kwiimpazamo zokuqala kunye nokuqokelela igesi kwenza kube yinto ebalulekileyo ekuqinisekiseni ukuthembeka kunye nokusebenza kwengqibelelo ye-transformer.

Isishwankathelo, amacandelo e-transformer asebenza kunye ukuze aququzelele ukudluliselwa kwamandla ombane ngokufanelekileyo. Ukususela kwii-windings eziphambili kunye nesekondari ukuya kwi-core transformer, izinto zokukhusela, iziguquli zompompo, kunye nezixhobo zokukhusela ezifana ne-Buchholz relay, icandelo ngalinye lidlala indima ebalulekileyo ekuqinisekiseni ukusebenza okuthembekileyo nokukhuselekileyo kwe-transformer. Ukuqonda la macandelo kubalulekile ukugcina ukusebenza kunye nobomi obude beenguqu kwiinkqubo zombane.
