Demagnetization Nzira uye Basa re900kw Diesel Jenareta

900kw dhiziri jenareta, sea high-simba jenareta set , ane simba rakazara uye simba rakasimba.Panguva imwecheteyo, seti dhiziri jenareta seti, ine maitiro ekushanda kuri nyore uye kugadzirisa kuri nyore.Zvakawanda sei zvaunoziva nezve demagnetization nzira uye basa re900kw dhiziri jenareta?

Jenareta redhiziri re900kw rinobva rava de-excitation.

Uchishandisa inverter inoshanda mamiriro echitatu-chikamu chekutonga-chakazara bhiriji, yekudzora angle inoshandurwa kubva pakugadzirisa kushanda mamiriro ari pasi pe90 ° kuenda kune yakakodzera kona yakakura kupfuura 90 °.Panguva ino, simba rekusimudzira rinoshandurwa uye rinoshandiswa kumhepo yekukurudzira nenzira yeEMF yekumashure., The de-excitation process umo rotor current inokurumidza kuora kusvika zero inonzi inverter de-excitation.Iyi de-excitation nzira inokurumidza kudyisa kudzorera rotor simba rekuchengetedza kune AC side simba remagetsi matatu-pase-yakazara-kudzora zambuko, uye haidi discharge resistors kana arc kudzimisa grids.Iyo iri nyore uye inoshanda de-excitation nzira.Nekuti hapana chekubata, hapana arc, uye hapana huwandu hukuru hwekupisa hunogadzirwa, iyo demagnetization yakavimbika.Iyo yakakura iyo kumashure EMF, iyo inokurumidza kukurumidza demagnetization.Iyo EMF yekumashure inogadzirwa panguva yekushandurwa kweiyo-nhatu-chikamu-yakazara-yakazara bhiriji yakanyatso kuenzana nevoltage yeAAC side magetsi, saka kukosha kweiyo kumashure EMF kunogumira kune imwe nhanho.Panguva imwecheteyo, iyo hombe yekudzora max (kana diki inverter angle min) yakagadzirirwa kudzivirira "inverter subversion".Iyo yekugumira ye) zvakare inoderedza iyo kumashure EMF kune imwe nhanho.Naizvozvo, single inverter demagnetization inogumira neiyo AC simba voltage.Munguva ye inverter demagnetization, iyo yekukuchidzira ikozvino inoderera mutsara, asi iyo yakashandiswa kumashure-EMF kukosha panguva inverter demagnetization idiki pane iyo yearc yekudzima grid demagnetization nzira, saka yazvino inoderedza Mwero idiki, iyo demagnetization nguva yakareba, asi iyo overvoltage yakawanda zvakare yakaderera kwazvo.

900kw dizeli jenareta isiri-mutsara inopikisa demagnetization.

Kana iyo excitation system yakavharwa zvakajairika, iyo regulator ichaita otomatiki demagnetize ne inverter;kana yakavharwa netsaona, iyo demagnetization switch inosvetuka kuendesa iyo magineti simba kune inopedza simba resistor kuti demagnetize.Kana jenareta iri munzvimbo isina kujairika yekushanda senge kutsvedza, yakakwira zvakanyanya induced voltage inogadzirwa mudunhu rerotor.Panguva ino, iyo rotor overvoltage yekuona unit A61 module yakaiswa mu rotor circuit ichaona rotor mberi overvoltage chiratidzo uye pakarepo Trigger V62 thyristor element, batanidza simba dissipation resistor unit FR mu rotor circuit, uye kubvisa inogadzirwa overvoltage simba kuburikidza. kutorwa kwesimba kwesimba rekubvisa simba rekudzivirira;uye reverse overvoltage signal ye rotor circuit yakananga inopfuura neV61 yechipiri chubhu Iro simba rekudzivirira simba rinosungirirwa kuti ritore simba kuti rive nechokwadi chokuti jenereta rotor haizombofi yakazarura dunhu, kuitira kuchengetedza zvakavimbika rotor insulation kubva mukukuvara.Nekuda kwekuvapo kwedziviriro yerudzi urwu, iyo rotor inotenderera inoburitsa yakatarisana nemagnetic field, iyo inogona kumisa reverse remagineti inogadzirwa neasina kunaka kutevedzana ikozvino kwe stator, kuitira kuchengetedza rotor pamusoro uye rotor guard ring kubva. kutsva.

Basa re900kw dizeli jenareta magnetoresistance.

Mhepo yekunakidzwa kwea 900kw dhiziri jenareta icoil ine inductance yakakura.Mumamiriro ezvinhu akajairwa, iko zvino kuwedzeredza kunogadzira yakasimba magineti pane jenareta rotor.Kana jenareta redhiziri re900kw rikatadza mukati, zvinofanirwa kukurumidza kucheka excitation ikozvino uye kubvisa iyo magnetic field ye900kw dhiziri jenareta kudzivirira kuwedzera kwetsaona.Zvisinei, zvakanyanya kuoma kushandisa shanduko kuti ubvise zvakananga ikozvino munharaunda yakadaro ine inductance yakakura.Nekuti zvakananga kucheka iyo yekuwedzeredza ikozvino inoburitsa yakakwira voltage kumagumo ese emhepo yekukurudzira, iyo inogona kupisa madhijitari.Naizvozvo, usati wacheka dunhu rekusimudzira, tanga wabatanidza de-excitation kuramba pamigumo miviri ye rotor mune parallel, kuitira kuti kana iyo excitation yedunhu yagurwa, de-excitation resistance inogona kukurumidza kutora simba remagineti remhepo yekukurudzira. , inonotsa rotor ikozvino shanduko yekukurumidza, uye kuderedza rotor self Iyo induced electromotive force inotamba chinangwa chekudzikisa rotor overvoltage uye demagnetization.

The de-excitation resistance is not when the 900kw diesel jenareta inofananidzwa kana de-arranged, asi kana 900kw dhiziri generator inoshandiswa, de-excitation resistor inoiswa uye inoiswa kumativi ose e rotor coil. The de-excitation switch is a switch inoshandiswa kukurumidza kuderedza ikozvino mumhepo yekusimudzira.Usati watanga kuvaka voltage, isa mu de-excitation switch.Kana pakaitika 900kw jenareta redhiziri kana tsaona, fambisa de-excitation switch kuti udimbure excitation circuit current kuti uwane chinangwa chekudzikisa simba re 900kw dhiziri jenareta.

mhedzisiro:

(1) Iko kukurumidza kugura 900kw dhiziri jenareta excitation mhepo uye excitation simba nzira.

(2) Kurumidza kudzima magineti mukati me900kw dhiziri jenareta.

Iyo iri pamusoro ndiyo nzira ye demagnetization uye basa re900kw dhiziri jenareta rakaunzwa neDingbo Power.Kana iwe uchifarira majenareta edhiziri, ndapota bata Dingbo Powet neemail.Dingbo Power ichakushandira wakatendeka.Imeiri yedu iri dingbo@dieselgeneratortech.com.
