Kodi Ubwino Wachitetezo cha Silent Diesel Generator Sets ndi chiyani

Silent genset amatha kuchepetsa phokoso ndipo amadziwika kwambiri m'malo okhala, zipatala ndi malo ena.M'zaka zaposachedwapa, msika wa majenereta a dizilo opanda phokoso wakhala wovuta kwambiri.Tiyeni tiwone majenereta a dizilo opanda phokoso pansipa.Ubwino khumi wachitetezo.

1. Silent dizilo jenereta imfa-ya-chisangalalo chitetezo.

Chitetezo cha kutaya-chisangalalo chimagwiritsidwa ntchito ngati kutayika kwa chiwopsezo chachitetezo pamene mphamvu yamagetsi ya jenereta imatsika mosadziwika bwino kapena kutha kwathunthu.Zimapangidwa ndi njira monga excitation low voltage Ufd(P), low voltage, static stability impedance, TV disconnection yomwe mtengo wake umasintha ndi mphamvu yogwira ntchito, yomwe imagwira ntchito posayina ndi kutulutsa chisangalalo motsatira.Onse mafunde otsika voteji Ufd (P) muyezo ndi malo amodzi bata Impedans muyezo zikugwirizana ndi malo amodzi kukhazikika malire, amene angathe kudziwa ngati jenereta amataya kukhazikika malo amodzi chifukwa imfa ya chisangalalo.Mulingo wokhazikika wa static Impedans umagwira pamalire okhazikika pambuyo pakutayika kwa maginito.

2. Mute dizilo jenereta overexcitation chitetezo.

Chitetezo chambiri ndi chitetezo chomwe chimawonetsa kuchulukitsitsa kwa maginito kwapakati pachitsulo komwe kumachitika chifukwa cha kuchepetsedwa kwa ma frequency a jenereta kapena mphamvu yamagetsi kwambiri.Chitetezo cha overexcitation chimagawidwa m'makonzedwe apamwamba ndi otsika.Malo otsika amatumiza chizindikiro pambuyo pa kuchedwa kwa 5s ndikuchepetsa mphamvu yachisangalalo (ntchito yochepetsera magetsi otsekemera ndi mphamvu zowonongeka ndizosagwiritsidwa ntchito kwakanthawi), ndipo mawonekedwe apamwamba amagwira ntchito pakutsitsa pambuyo pa malire a nthawi yosiyana.Demagnetization.Malire apamwamba a kuchedwa kwa nthawi yosiyana ndi masekondi a 5, ndipo malire apansi ndi masekondi 200.

3. Chete dizilo jenereta stator grounding chitetezo.

Jenereta stator grounding chitetezo ntchito ngati jenereta stator single-gawo maziko chitetezo cholakwa.Lili ndi magawo awiri: gawo loyambira zero sequence voltage ndi lachitatu voteji ya harmonic.Mphamvu yotsatizana ya zero imateteza gawo limodzi lokhazikika la stator m'dera la 95% kuchokera kumapeto kwa makina mpaka kumchira wamakina.Kulakwitsa kwapansi kumapangidwa ndikuwonetsa mfundo ya voteji yotsatizana zero kumapeto kwa jenereta, yomwe imagwira ntchito pa demagnetization pakadutsa nthawi ya T1 (3s);wachitatu voteji harmonic amateteza limodzi gawo grounding kulakwa kwa stator mapindikidwe kuchokera jenereta mchira kwa 30% ya mapeto jenereta.Mfundo yosalowerera ndale ya jenereta ndi mfundo yachitatu-harmonic kumapeto kwa jenereta imapangidwa, ndikuchitapo chizindikiro pambuyo pa nthawi ya T2 (5s).Awiriwa amapanga chitetezo cha 100% stator grounding.Chitetezo chimakhala ndi loko ya PT.

4. Silent dizilo jenereta stator kutembenukira chitetezo.

Chitetezo chimapangidwa ndi voteji yotsatizana ya zero yotalikirapo komanso njira yotsatizana yolakwika ya gawo lolakwika.Njira zotsekera za PT zimakhazikitsidwa ngati chitetezo chachikulu cha jenereta yamkati ndi gawo lalifupi komanso kuwotcherera kotseguka kwa mafunde a stator.Kuzindikira mphamvu yotsatizana yolakwika yomwe ikutuluka mu jenereta kuti izindikire kuchuluka kwa voteji ya zero-sequence voltage imazindikirika pozindikira kutulutsa kwakutali kwa 3UO ndi 3PT yotseguka yotsegulira delta yomwe malo osalowerera ndale ali mwachindunji. olumikizidwa ku gawo lopanda ndale la jenereta koma osakhazikika.Ntchito yachitetezo ili pachimake.

5. Silent dizilo jenereta kunja kwa sitepe chitetezo.

Chitetezo chimagwiritsa ntchito chinthu chachitatu-impedance kuti chizindikire kuchuluka kwa mizati yotsetsereka ndikuzindikira komwe kuli malo oscillation kudzera pakusintha kwa njira ya impedance.Pankhani ya vuto laling'ono, kutsika kwadongosolo, kutsekedwa kwamagetsi, ndi zina zotero, chitetezo sichidzagwira ntchito.Chitetezo nthawi zambiri chimagwira pa chizindikiro;pamene malo oscillation ali mkati mwa gulu la jenereta-transformer, siteji ya chitetezo ndikuyamba ndikutumiza lamulo laulendo kudzera pa t1 (0.5s), yomwe imagwira ntchito pa de-excitation;pamene malo oscillation ali kunja kwa gulu la jenereta-transformer, chitetezo Kuyamba kwa gawo II kumatchulidwa pa t2 (2s).Chipangizo chotetezera chimakhala ndi chipangizo chotchinga chamakono kuti chiwonetsetse kuti panopa sichikupitirira mlingo wosweka wamagetsi wamagetsi pamene wodutsa dera watsekedwa.

6. Kutetezedwa kwapang'onopang'ono kwa majenereta a dizilo opanda phokoso.

Chitetezo chotsika pafupipafupi chimakhudzidwa ndi kuchuluka kwa kuchepetsedwa kwa ma frequency a system pa turbine ya nthunzi.Chitetezo chimakhala ndi ma frequency frequency relay ndi counter, ndipo chimatsekedwa ndi kukhudzana kothandizira kwa chowotcha dera (ndiko kuti, chitetezo chocheperako chimatulukanso pomwe jenereta ikutuluka), ndipo ma frequency a system owonjezera amakhala otsika. pafupipafupi imayikidwa pa 47.5 Hz, pamene nthawi yochuluka ikufika pamtengo wokhazikika wa masekondi a 3000, chizindikirocho chidzatumizidwa pambuyo pa kuchedwa kwa masekondi a 30.Chipangizochi chikhoza kuyang'aniridwa mu nthawi yeniyeni panthawi yogwira ntchito: mtengo wokhazikika, ma frequency f ndi chiwonetsero cha nthawi yowonjezera.

7. Chete dizilo jenereta chisangalalo dera zimamuchulukira chitetezo.

Chitetezo chowonjezera chozungulira chimagwiritsidwa ntchito kuteteza dera losangalatsa la rotor kuti lisapitirire kapena kulemetsa.Imalumikizidwa mumtundu wa magawo atatu ndipo imakhala ndi magawo awiri: nthawi yotsimikizika komanso malire a nthawi yosiyana.Kugwira ntchito kwa gawo lodziwika la nthawi kumayikidwa molingana ndi momwe kungabwezedwe modalirika pansi pa kuchuluka kwazomwe zimagwiritsidwa ntchito nthawi zonse.Pambuyo pa malire a nthawi t1 (5s), imagwira ntchito pa chizindikirocho ndipo imachepetsa mphamvu yachisangalalo (ntchito yochepetsera mphamvu yowonongeka sikugwiritsidwa ntchito);mawonekedwe a gawo la nthawi yosiyana ndi molingana ndi jenereta Kuchulukira kwa mafunde osangalatsa kumatsimikiziridwa, ndipo chitetezo chili pakuchotsa mphamvu ndikuchotsa.Malire apamwamba a malire a nthawi yosiyana ndi masekondi 10.

8. Kutetezedwa kwa mfundo imodzi kwa rotor ya jenereta ya dizilo yopanda phokoso.

Jenereta ya rotor yokhala ndi mfundo imodzi yodzitchinjiriza imagwiritsidwa ntchito kuwonetsa cholakwika cha gawo limodzi la gawo la jenereta.Chitetezo chimatengera mfundo yosinthira ping-pong.Ma voltages abwino ndi oyipa a gawo la rotor amatsatiridwa motsatizana, ndipo kukana kwa rotor kumawerengedwa munthawi yeniyeni pothetsa ma equation awiri osiyana a loop.Ndipo poyambira.Chitetezo chidzachitapo kanthu pambuyo pa kuchedwa kwa masekondi a 2.

9. Symmetrical overload chitetezo kwa mwakachetechete majenereta dizilo.

Chipangizo chotetezera chimapangidwa ndi magawo awiri: nthawi yotsimikizika komanso malire a nthawi yosiyana.Gawo lotsimikizika la nthawi limachita pa siginecha pambuyo pa malire a masekondi 5.Mawonekedwe a nthawi yosinthira amatsimikiziridwa molingana ndi mphamvu ya jenereta yolimbana ndi kuchuluka kwaposachedwa, ndipo zomwe zikuchitika ndikutsitsa.Chipangizo chotetezera chikhoza kuwonetsa ndondomeko ya kutentha kwa stator ya jenereta.

10. Kutetezedwa kotsatizana koyipa kwa majenereta a dizilo opanda phokoso.

Chipangizo chotetezera chimapangidwa ndi magawo awiri: nthawi yotsimikizika komanso malire a nthawi yosiyana.Zomwe zatsala pang'ono kuchitapo kanthu zimayikidwa molingana ndi nthawi yayitali yovomerezeka yolakwika pamtengo wapano wa jenereta ndi mtengo wamakono umene umapewa kusagwirizana kwa ndondomeko yolakwika yamakono fyuluta pansi pa katundu wambiri.Wachiwiri amachita pa chizindikiro.Mawonekedwe a nthawi yosinthira amatsimikiziridwa molingana ndi kuthekera kwa jenereta kupirira motsatana molakwika pakali pano, ndipo zomwe zimachitikazo zili mu de-excitation ndi de-excitation.

Ngati mukufuna kudziwa zambiri za majenereta a dizilo, talandiridwa kuti mulumikizane ndi imelo dingbo@dieselgeneratortech.com.
