1. Transformer inoshandura sei voltage?
Iyo transformer inogadzirwa zvichibva pane electromagnetic induction. Iyo ine simbi yesimbi yakagadzirwa nesilicon simbi mashiti (kana silicon simbi mashiti) uye maviri seti emakoiri akakuvadzwa pasimbi simbi. Iyo iron core uye macoils ari insulated kubva kune mumwe uye haana magetsi ekubatanidza.
Izvo zvakasimbiswa nedzidziso kuti chiyero chevoltage pakati peiyo yekutanga coil uye yechipiri coil ye transformer ine hukama nereshiyo yehuwandu hwekutendeuka kweiyo yekutanga coil uye yechipiri coil, iyo inogona kuratidzwa neinotevera fomula: yekutanga coil. voltage/secondary coil voltage = primary coil inotendeuka/secondary coil inotendeuka. Kuwedzera kutendeuka, kuwedzera kwemagetsi. Naizvozvo, zvinogona kuoneka kuti kana iyo yechipiri coil iri pasi peiyo yekutanga coil, inhanho-pasi transformer. Pane zvinopesana, inhanho-up transformer.
2. Ndeupi hukama huripo pakati pekutanga coil uye yechipiri coil ye transformer?
Kana iyo transformer ichimhanya nemutoro, shanduko mune yechipiri coil ikozvino ichakonzera shanduko inoenderana mune yekutanga coil ikozvino. Zvinoenderana neiyo nheyo yemagineti inogona kuenzana, inopesana neyakajairwa yekutanga uye yechipiri coils. Ikozvino padivi ine matende akawanda idiki, uye ikozvino padivi ine mashoma anotendeuka yakakura.
Inogona kuratidzwa neinotevera formula: yekutanga coil ikozvino / yechipiri coil ikozvino = yechipiri coil inotendeuka / yekutanga coil inotendeuka.
3. Nzira yekuita sei kuti transformer ine rated voltage output?
Voltage yakakwira zvakanyanya kana yakadzikira inokanganisa kushanda kwakajairwa uye hupenyu hwesevhisi yetransformer, saka mutemo wemagetsi unodiwa.
Iyo nzira yekudzora magetsi ndeyekutungamirira kunze akati wandei matepi mune yekutanga coil uye oabatanidza kune iyo tap inoshandura. Iyo pombi inoshandura inoshandura nhamba yekutendeuka kwecoil nekutenderedza macontacts. Chero bedzi nzvimbo yepombi inoshandura ichishandurwa, iyo inodiwa yakatemerwa voltage kukosha inogona kuwanikwa. Izvo zvinofanirwa kucherechedzwa kuti voltage regulation inowanzoitwa mushure mekunge mutoro wakabatanidzwa kune transformer wagurwa.
4. Ndezvipi zvinorasikirwa ne transformer panguva yekushanda? Nzira yekudzikisa sei kurasikirwa?
Iko kurasikirwa mukushanda kwetransformer kunosanganisira zvikamu zviviri:
(1) Zvinokonzerwa nesimbi. Kana iyo coil ichinge yasimbiswa, iwo magineti mitsara yesimba inochinjana, ichikonzera eddy ikozvino uye hysteresis kurasikirwa musimbi musimboti. Kurasikirwa uku kunonzi pamwe chete kurasikirwa kwesimbi.
(2) Inokonzerwa nekupikisa kwecoil pachayo. Kana ikozvino ichipfuura nepakati pekutanga uye yechipiri coils ye transformer, kurasikirwa kwemagetsi kuchagadzirwa. Kurasika uku kunonzi kurasikirwa kwemhangura.
Huwandu hwekurasikirwa kwesimbi uye kurasikirwa kwemhangura ndiko kurasikirwa kweshanduko. Kurasikirwa uku kune hukama neiyo transformer simba, voltage uye kushandiswa kwemidziyo. Nokudaro, pakusarudza transformer, simba rekushandisa rinofanira kuenderana nekushandiswa chaiko sezvinobvira kuvandudza kushandiswa kwemidziyo, uye kutarisirwa kunofanira kutorwa kusashandisa transformer pasi pemutoro wakajeka.
5. Chii chinonzi nameplate chetransformer? Ndeapi makuru ehunyanzvi data pane nameplate?
Iyo nameplate ye transformer inoratidza mashandiro, tekinoroji maratidziro uye mamiriro ekushandiswa kweshanduro kuti asangane nesarudzo yemushandisi. Iwo makuru ehunyanzvi data anofanirwa kutariswa panguva yekusarudza ndeaya:
(1) Iyo kilovolt-ampere yehuwandu hwakayerwa. Ndiko kuti, iyo inobuda simba ye transformer pasi peyakarongwa mamiriro. Semuenzaniso, chiyero chakayerwa chega-phase transformer = U mutsara× I line; kugona kweatatu-phase transformer = U mutsetse× I line.
(2) The rated voltage in volts. Ratidza iyo terminal voltage yeyekutanga coil uye terminal voltage yeyechipiri coil (kana isina kubatana kumutoro) zvichiteerana. Ziva kuti iyo terminal voltage yetatu-phase transformer inoreva mutsara voltage U mutsetse kukosha.
(3) Iyo yakayerwa ikozvino muampere. Inoreva mutsara wazvino I mutsara kukosha iyo yekutanga coil uye yechipiri coil inotenderwa kupfuura kwenguva yakareba pasi pemamiriro ekuyerwa kugona uye inobvumirwa tembiricha kukwira.
(4) Voltage ratio. Zvinoreva chiyero cheiyo yakayerwa voltage yeiyo yekutanga coil kune yakayerwa voltage yeyechipiri coil.
(5) Wiring nzira. A single-phase transformer ine chete seti imwe chete yepamusoro uye yakaderera voltage coils uye inongo shandiswa kune imwechete-phase kushandiswa. A matatu-phase transformer ane Y/△type. Pamusoro peiyo yepamusoro data data, kune zvakare yakayerwa frequency, nhamba yezvikamu, kukwira kwekushisa, impedance percentage ye transformer, nezvimwe.
6. Ndezvipi zviedzo zvinofanira kuitwa pane transformer panguva yekushanda?
Kuti uve nechokwadi chekushanda kwakajairika kweshanduko, bvunzo dzinotevera dzinofanirwa kuitwa kazhinji:
(1) Kuedzwa kwetembiricha. Kupisa kwakakosha zvikuru kuona kana transformer iri kushanda zvakajairika. Mitemo inotaura kuti tembiricha yemafuta epamusoro haifanire kudarika 85C (kureva, kukwira kwekushisa i55C). Kazhinji, ma transformer ane akakosha ekuyeresa tembiricha michina.
(2) Mutoro kuyerwa. Kuti uvandudze huwandu hwekushandiswa kweshanduko uye kuderedza kurasikirwa kwesimba remagetsi, simba rekupa simba iro transformer rinogona kutakura rinofanira kuyerwa panguva yekushanda kweshanduko. Basa rekuyera rinowanzoitwa panguva yepamusoro yekushandiswa kwemagetsi mumwaka wega wega, uye inoyerwa zvakananga ne clamp ammeter. Iko kukosha kwemazuva ano kunofanira kuva 70-80% yehuwandu hwemazuva ano ekushandura. Kana ichipfuura chiyero ichi, zvinoreva kuwandisa uye inofanira kugadziriswa nekukasira.
(3)Voltage kuyerwa. Mitemo inoda kuti voltage yekuchinja siyana inofanira kunge iri mukati±5% yemagetsi akayerwa. Kana ikadarika chiyero ichi, pombi inofanira kushandiswa kugadzirisa voltage kune yakataurwa. Kazhinji, voltmeter inoshandiswa kuyera yechipiri coil terminal voltage uye terminal voltage yemushandisi wekupedzisira zvakateerana.
Mhedziso: Yako Yakavimbika Simba Partner Sarudza JZPnokuda kwezvido zvako zvekugovera simba uye unowana mutsauko uyo hunhu, hutsva, uye kuvimbika kunogona kuita. Yedu Single Phase Pad-Mounted Transformers akagadzirwa kuti ape mashandiro epamusoro, kuve nechokwadi chekuti masisitimu ako emagetsi anoshanda zvakanaka uye nemazvo. Bata nesu nhasi kuti udzidze zvakawanda nezve zvigadzirwa zvedu uye kuti tingakubatsira sei kuzadzisa zvinangwa zvako zvekugovera simba.
