Muchina wekuchinja tepi weTransformer

Mudziyo unodzora voltage wetransformer wakakamurwa kuita mudziyo unodzora voltage wetransformer "off-excitation" uye muchina wekuchinja "on-load" wetransformer.

Ose ari maviri anotaura nezve voltage regulating mode ye transformer tap changer, saka musiyano uripi pakati pezviviri izvi?

① "Kuchinja-chinja" kwepombi kunofanirwa kuchinja pombi yepamusoro yetransformer kuti ichinje chiyero chekutenderera kwewinding yemagetsi kana mativi ese ekutanga neechipiri etransformer abviswa pamagetsi.

② Chinochinja pombi "Panotakurwa": Uchishandisa chinochinja pombi chiri painotakurwa, pombi yetransformer inochinjwa kuti ichinje matenderedzwa emagetsi ane simba guru kuti pave nekudzora voltage pasina kudzima load current.

Musiyano uripo pakati pezviviri izvi ndewekuti chinochinja magiya chisiri kuburitsa simba hachina simba rekuchinja magiya ne load, nekuti rudzi urwu rwechichinja magiya rune nzira yekubvisa magetsi kwenguva pfupi panguva yekuchinja magiya. Kubvisa simba remagetsi kunokonzera kutenderera pakati pema contacts uye kukuvadza chinochinja magiya. Chinochinja magiya chiri pa load chine nzira yekuchinja simba zvakanyanya panguva yekuchinja magiya, saka hapana nzira yekubvisa magetsi kwenguva pfupi. Pakuchinja kubva pane rimwe giya kuenda kune rimwe, hapana nzira yekubvisa magetsi kana simba remagetsi rabviswa. Inowanzo shandiswa kune ma transformer ane zvinodiwa zve voltage zvakanyanya zvinoda kugadziriswa nguva nenguva.

Sezvo transformer "inopa mutoro" ichigona kuona mashandiro emagetsi pasi pemamiriro ekushanda kwetransformer, sei uchifanira kusarudza "inopa mutoro" tap changer? Ehe, chikonzero chekutanga mutengo. Mumamiriro ezvinhu akajairwa, mutengo weinopa mutoro Transformer yeTap Changer i2/3 yemutengo wetransformer inochinja tap inoiswa pamutoro; panguva imwe chete, huwandu hwetransformer inochinja tap inoiswa pamutoro hudiki zvikuru nekuti haina chikamu chinochinja tap inoiswa pamutoro. Saka, kana pasina mitemo kana mamwe mamiriro ezvinhu, transformer inochinja tap inoiswa pamutoro ichasarudzwa.

Sei uchifanira kusarudza transformer inochinja pombi iri pamutoro? Basa rayo nderei?
① Wedzera mwero wemagetsi anodiwa.
Kutapurirana kwesimba mu network yekugovera magetsi kunounza kurasikirwa, uye kukosha kwekurasikirwa ndiko kudiki pane voltage yakayerwa chete. Kuita mutemo we voltage on-load, kugara uchichengetedza voltage ye substation bus inokodzera, uye kuita kuti michina yemagetsi ishande pa rated voltage state kunoderedza kurasikirwa, iyo iri iyo inodhura zvakanyanya uye ine musoro. Mwero we voltage qualification ndeimwe yezviratidzo zvakakosha zvemhando yemagetsi. Kutonga voltage on-load panguva yakakodzera kunogona kuve nechokwadi chekuti voltage qualification rate, nokudaro zvichizadzisa zvinodiwa nehupenyu hwevanhu uye kugadzirwa kwemaindasitiri nekurima.

② Wedzera simba rekugadzirisa reactive power uye wedzera chiyero chekupinda kwe capacitor.
Semudziyo wekugadzirisa simba remagetsi, simba rinobuda remagetsi remagetsi rinoenderana nechiyero chevoltage yekushanda. Kana voltage yekushanda yesystem yemagetsi yadzikira, simba rekugadzirisa rinodzikira, uye kana voltage yekushanda ikawedzera, michina yemagetsi inobhadharwa zvakanyanya, zvichiita kuti voltage yeterminal iwedzere, zvichitopfuura mwero wezvinodiwa, izvo zviri nyore kukuvadza insulation yemidziyo uye kukonzera
tsaona dzemidziyo. Kuti simba remagetsi rirege kudzoserwa kumagetsi uye kuti michina yemagetsi inotsiva magetsi irege kudzimwa, zvichikonzera kurasika kwemagetsi uye kurasikirwa kwakanyanya kwemidziyo yemagetsi inotsiva magetsi, switch huru yetransformer inofanira kugadziriswa nenguva kuti igadzirise voltage yebhazi kuenda kune range yakakodzera, kuitira kuti pasave nechikonzero chekudzima capacitor compensation.

Maitiro ekushandisa mutemo wemagetsi ari pamutoro?
Nzira dzekugadzirisa voltage iri pamutoro dzinosanganisira kugadzirisa voltage yemagetsi uye kugadzirisa voltage yemaoko.

Chinangwa chikuru chekutonga kwevoltage on-load ndechekugadzirisa voltage nekugadzirisa transformation ratio yedivi re-high-voltage nepo voltage iri kudivi re-low-voltage ichiramba isina kuchinja. Tose tinoziva kuti high-voltage side inowanzova system voltage, uye system voltage inowanzogara iripo. Kana nhamba yekutenderera pa high-voltage side winding yawedzerwa (ndiko kuti, transformation ratio yawedzerwa), voltage iri kudivi re-low-voltage ichaderera; pane zvinopesana, kana nhamba yekutenderera pa high-voltage side winding yaderedzwa (ndiko kuti, transformation ratio yaderedzwa), voltage iri kudivi re-low-voltage ichawedzera. Ndizvo:

Kuchinjana kwekuwedzera = kudzika = kuderedzwa kwemagetsi Kuderedza kutendeuka = ​​kukwira = kuwedzera kwemagetsi
Saka, chii chingatadzisa transformer kuchinja pombi kana paine mutoro?
① Kana transformer yakawandisa (kunze kwemamiriro ezvinhu chaiwo)
② Kana alarm yegesi yechiedza chemuchina wekugadzirisa voltage uri pamutoro yatanga kushanda
③ Kana simba remagetsi ari pa-load voltage richiramba kushanda zvakanaka kana kuti pasina mafuta ari muchiratidzo chemafuta, ziva kuti hapana mafuta aripo.
④ Kana huwandu hwemagetsi huchipfuura huwandu hwakatarwa
⑤ Kana mudziyo wekugadzirisa voltage usina kunaka

Sei overload ichivharawo pombi inochinja zvinhu painoda kudzoserwa?
Izvi zvinodaro nekuti mumamiriro ezvinhu akajairwa, panguva yekudzora voltage iri pamusoro pemutoro wetransformer huru, pane musiyano wevoltage pakati pechinobatanidza chikuru netap inotarirwa, iyo inogadzira circulating current. Saka, panguva yekudzora voltage, resistor yakabatana pamwe chete kuti ipfuure circulating current uye load current. Parallel resistor inofanira kutsungirira current yakakura.

Kana transformer yemagetsi yakawandisa, simba rekushanda kwetransformer huru rinodarika simba remagetsi rakatarwa remuchina wekuchinja tap, izvo zvinogona kupisa chinobatanidza chemuchina wekuchinja tap.

Saka, kuitira kudzivirira chiitiko chekuchinjisa pombi, hazvibvumidzwe kuita mutemo wemagetsi ari pamutoro kana transformer huru yakawandisa. Kana mutemo wemagetsi ukamanikidzwa, mudziyo wemagetsi ari pamutoro unogona kutsva, gasi remutoro rinogona kuvhurwa, uye switch huru yetransformer inogona kugumburwa.
