Intshayelelo
I-Transformer sisixhobo esimileyo esiguqula amandla ombane e-AC ukusuka kumbane omnye ukuya komnye amandla ombane okugcina amaza ombane afanayo ngomgaqo wokungeniswa kombane.
Igalelo kwi-transformer kunye nemveliso evela kwi-transformer zombini zizixa ezitshintshanayo (AC) .Amandla ombane aveliswa kwaye adluliselwe kumbane ophezulu kakhulu. Amandla ombane kufuneka ke acuthwe abe lixabiso eliphantsi kusetyenziso lwasekhaya kunye neshishini. Xa i-transformer itshintsha inqanaba le-voltage, itshintsha inqanaba langoku.
UmGaqo wokuSebenza
Umoya ophambili uqhagamshelwe kwi-single - phase ac supply, i-ac current iqala ukuhamba kuyo. I-ac primary current ivelisa i-alternating flux (Ф) kwi-core. Uninzi lolu tshintsho lutshintshayo ludityaniswa nokujika kwesibini kumbindi.
Ukuguquguquka okwahluka-hlukeneyo kuya kubangela amandla ombane kwi-winding yesibini ngokwemithetho ye-faraday yokungeniswa kombane. Ukutshintsha komgangatho wombane kodwa amaxesha ngamaxesha, oko kukuthi, ixesha lihlala lifana. Akukho kudityaniswa kombane phakathi kokujija kubini, amandla ombane akhutshelwa ukusuka kwindawo yokuqala ukuya kweyesibini.
Isiguquli esilula siquka izikhondaktha zombane ezimbini ezibizwa ngokuba yi-primary winding kunye nesecondary winding. Amandla adityaniswa phakathi kwamajiko-jiko ngexesha lokuguquguquka kwemagnethi edlula kwi( amakhonkco) omabini amajiko-jiko aphambili kunye nawesibini.
Izincedisi ezibalulekileyo zeSiguquli saMandla
1.Buchholz relay
Le relay yenzelwe ukufumanisa impazamo yangaphakathi ye-transformer kwinqanaba lokuqala ukuphepha ukuphuka okukhulu. I-float ephezulu iyajikeleza kwaye itshintshe abafowunelwa ngokuvala kwaye ngaloo ndlela inika i-alamu.
2.I-Oil Surge Relay
Le relay inokutshekishwa ngokucinezela uvavanyo iswitshi enikwe kwicala eliphezulu. Apha mnye kuphela umfowunelwa onikiweyo onika umqondiso wohambo ekusebenzeni kokudada. Ngoqhagamshelwano olufutshane lwangaphandle ngekhonkco, isiphaluka sohambo sinokujongwa kwakhona.
3.I-Explosion Vent
Iquka umbhobho ogobileyo kunye ne-Bakelite diaphragm kuzo zombini iziphelo. I-mesh yocingo yokukhusela ifakwe ekuvuleni kwe-transformer ukukhusela iziqwenga ze-diaphragm eziqhekekileyo ukuba zingene kwitanki.
4.Ivalufa yoNcedo loxinzelelo
Xa uxinzelelo kwitanki lunyuka ngaphezu komda wokhuseleko omiselwe kwangaphambili, le valve isebenza kwaye yenze le misebenzi ilandelayo: -
Ivumela uxinzelelo lwehle ngokuvula izibuko ngoko nangoko.
Inika imbonakalo ebonwayo yokusebenza kwevalvu ngokuphakamisa iflegi.
Isebenzisa iswitshi encinci, enika umyalelo wohambo kwi-breaker.
5.I-Oil Temperature Indicator
Luhlobo lwethemometha yokucofa, isebenza kumgaqo woxinzelelo lomphunga. Ikwabizwa ngokuba yigeyiji yeoli yamagnetic (MOG). Inepere yemagnethi. Udonga lwesinyithi lwetanki yesilondolozi lwahlula iimagnethi ngaphandle komngxuma. Umhlaba wemagnethi uyaphuma kwaye usetyenziselwa ukubonakalisa.
6.I-Winding Temperature Indicator
Ikwayafana ne-OTI kodwa inotshintsho. Iqukethe iprobe efakwe ii-2 capillaries. IiCapillaries ziqhagamshelwe ngemivumbo emibini eyahlukeneyo (esebenzayo/ehlawulayo). Le mvulo idityaniswe nesalathisi sobushushu.
7.Umlondolozi
Njengoko ukwanda kunye nokucutheka kwenzeka kwitanki engundoqo ye-transformer, ngenxa yoko kwenzeka into efanayo kwisilondolozi njengoko sidityaniswe kwitanki engundoqo ngombhobho.
8.Umzalwana
Esi sisihluzo somoya esikhethekileyo esibandakanya i-dehydrating material, ebizwa ngokuba yi-Silica Gel. Isetyenziselwa ukuthintela ukungena komswakama kunye nomoya ongcolileyo kwi-conservator.
9.IiRaditha
Abaguquli abancinci babonelelwa ngeetyhubhu zokupholisa ezidityanisiweyo okanye iiradiyetha zentsimbi ezicinezelweyo. Kodwa ii-transformers ezinkulu zibonelelwa ngeeradiyetha ezikwaziyo ukususwa kunye neevalvu. Ukupholisa okongeziweyo, iifeni zokukhupha zibonelelwa kwiiradiyetha.
10.Cofa iTshintsho
Njengoko umthwalo kwi-transformer inyuka, i-voltage yesibini ye-terminal iyancipha.Kukho iindidi ezimbini zokutshintsha impompo.
A.Off Umthwalo wokuTshintsha iTop
Kulo hlobo, ngaphambi kokuhambisa umkhethi, i-transformer yenziwe OFF kuzo zombini iziphelo. Abatshintshi bempompo abanjalo banemifowunelwa yobhedu esisigxina, apho iimpompo ziphelisiwe. Abafowunelwa abahambahambayo benziwe ngobhedu ngendlela efana ne-roller okanye icandelo.
B.On Layisha iTap Tshintshela
Ngokufutshane siyibiza ngokuba yi-OLTC. Kule nto, iimpompo zinokutshintshwa ngesandla ngokusebenza ngoomatshini okanye ngombane ngaphandle kokwenza i-transformer. Kumsebenzi woomatshini, uqhagamshelo lubonelelwa ngokungasebenzi kwe-OLTC ngezantsi kweyona ndawo iphantsi yempompo nangaphezulu kweyona ndawo iphezulu yempompo.
11.RTCC (ityhubhile yokulawula impompo ekude)
Isetyenziselwa ukutshintsha impompo ngesandla okanye ngokuzenzekelayo nge-Automatic Voltage Relay (AVR) esetelwe +/- 5% ye-110 Volt (Ireferensi ethatyathwe kwicala lesibini lombane le-PT).
