Nhanganyaya
Transformer chinhu chine static chinoshandura AC magetsi emagetsi kubva kune imwe voltage kuenda kune imwe voltage ichichengeta frequency yakafanana neelectromagnetic induction musimboti.
Input kutransformer uye yakabuda kubva kutransformer zvese zviri alternating quantities (AC) .Simba remagetsi rinogadzirwa uye rinofambiswa pakakwirira zvakanyanya. Iyo voltage inozoderedzwa kusvika pamutengo wakaderera wekushandisa kwayo mudzimba uye mumaindasitiri. Kana iyo transformer ichichinja iyo voltage level, inoshandura iyo yazvino nhanho zvakare.
Kushanda Nheyo
Iyo yekutanga mhepo yakabatana kune imwechete - phase ac supply, ac ikozvino inotanga kuyerera kuburikidza nayo. Iyo ac yekutanga ikozvino inoburitsa alternating flux (Ф) mukati mepakati. Yakawanda yeiyi shanduko inoshanduka inobatana neyechipiri inotenderera kuburikidza nepakati.
Iyo inosiyana inoyerera inopinza voltage mumhepo yechipiri zvinoenderana nemirairo yeFaraday yemagetsi induction. Voltage level shanduko asi frequency kureva nguva inoramba yakafanana. Iko hakuna magetsi ekubatana pakati pemapepo maviri, simba remagetsi rinotamiswa kubva kupuraimari kuenda kune yechipiri.
A simple transformer ine maviri emagetsi conductor anonzi primary winding and second winding. Simba rinosanganiswa pakati pematenderedzwa nenguva inosiyana magineti flux inopfuura ne(manongedzo) ese ekutanga uye echipiri mamhepo.
Zvinokosha Zvishandiso zveSimba Transformer
1.Buchholz relay
Iyi relay yakagadzirirwa kuona kukanganisa kwemukati kweshanduko muchikamu chekutanga kudzivirira kuparara kukuru. Iyo yekumusoro inoyangarara inotenderera & inochinja madhijitari kuvhara & nekudaro ichipa alarm.
2.Oil Surge Relay
Iyi relay inogona kutariswa nekudzvanya bvunzo switch yakapihwa kumusoro kudivi. Pano chete kubata kunopiwa kunopa chiratidzo cherwendo pakushanda kwekuyangarara. Nekupfupisa kuonana kwekunze nekubatanidza, rwendo rwedunhu runogonawo kutariswa.
3.Kuputika Kwemhepo
Iyo ine pombi yakabhenda ine Bakelite diaphragm kumativi ese ari maviri. Iyo yekudzivirira waya mesh yakaiswa pakuvhurwa kwetransformer kudzivirira zvidimbu zve diaphragm zvakatsemuka kupinda mutangi.
4.Pressure Relief Valve
Kana dzvinyiriro iri mutangi ichikwira pamusoro peyakafanotemerwa muganho wakachengeteka, vharuvhu iyi inoshanda & inoita mabasa anotevera: -
Inobvumira kudzvanywa kudonha nekuvhura chiteshi ipapo ipapo.
Inopa chiratidzo chekushanda kwevharuvhu nekusimudza mureza.
Inoshanda micro switch, iyo inopa rwendo kuraira kune breaker.
5.Oil Temperature Indicator
Iyo dial type thermometer, inoshanda pane iyo vapor pressure musimboti. Iyo inozivikanwawo semagnetic mafuta gauge (MOG). Iine magineti. Iyo metallic wall yeConservator tank inoparadzanisa magineti pasina chero nepaburi.Magnetic field inobuda uye inoshandiswa kuratidza.
6.Winding Temperature Indicator
Yakafananawo neOTI asi ine dzimwe shanduko. Inosanganisira probe yakaiswa 2 capillaries. Macapillaries akabatana nemabhero maviri akaparadzana (kushanda / kubhadharisa). Aya mabhero akabatana nechiratidzo chekushisa.
7.Conservator
Sezvo kuwedzera uye kudzvokora kunoitika mutransformer main tank, nekudaro chiitiko chimwe chete chinoitika muConservator sezvo chakabatana netangi huru kuburikidza nepombi.
8.Brother
Iyi sefa yakakosha yemhepo inosanganisira dehydrating material, inonzi, Silica Gel. Inoshandiswa kudzivirira kupinda kwehunyoro uye mhepo yakasvibiswa mukuchengetedza.
9.Radiators
Madiki Transformers anopihwa ane welded kutonhora machubhu kana akatsikirirwa sheet simbi radiators. Asi ma transformer mahombe anopihwa ma radiator anobatika pamwe nemavharuvhu. Kuti uwedzere kutonhora, mafeni ekupedza anopihwa pane radiators.
10.Tap Changer
Sezvo mutoro uri pa transformer unowedzera, yechipiri terminal voltage inoderera.Kune marudzi maviri epombi shanduko.
A.Off Load Tap Changer
Mune rudzi urwu, usati wafambisa sarudzo, transformer inogadzirwa OFF kubva kumativi ose. Vashanduri vepombi vakadaro vane macontacts endarira akagadziriswa, uko matepi anogumiswa. Iwo anofambisa anofambiswa anogadzirwa nendarira muchimiro cheimwe roller kana chikamu.
B.On Load Tap Changer
Muchidimbu tinoidaidza seOLTC. Mune izvi, matepi anogona kuchinjirwa pamaoko nemuchina kana kushanda kwemagetsi pasina kudzima transformer. Kushanda kwemakanika, kuvharika kunopihwa kusashanda kweOLTC pazasi pepombi yakaderera chinzvimbo uye pamusoro pepamusoro pombi chinzvimbo.
11.RTCC (Remote tap shanduko yekudzora cubicle)
Inoshandiswa pakuchinja tepi nemaoko kana otomatiki kuburikidza neAutomatic Voltage Relay (AVR) iyo yakaiswa +/- 5% ye110 Volt (Reference yakatorwa kubva kudivi rechipiri PT voltage).
