Wopanga Majenereta Chitetezo Chakunja kwa sitepe

Jenereta stator pansi zolakwa chitetezo kwa jenereta stator imodzi-gawo gawo pansi chitetezo chitetezo, katatu ndi zina zofunika zero ndondomeko voteji ndi harmonic voteji mbali ziwiri, woyamba harmonic ziro zinayendera voteji chitetezo makina mchira mapeto 95% m'dera la stator yokhotakhota limodzi- gawo lokhazikitsira cholakwika, mawonekedwe amphamvu owonetseredwa mu zero sequence voltage mfundo, pofika nthawi ya t1 (3 s) atchule maginito mu njira;Wachitatu harmonic voteji amateteza stator mapiringidzo limodzi gawo grounding cholakwa kuchokera mchira mpaka 30% ya mapeto a makina, amene wapangidwa ndi jenereta ndale mfundo ndi mfundo ya harmonic wachitatu wa mapeto a makina, ndi kuchita pa chizindikiro kudzera mu nthawi T2 (5s).Zonsezi zimapanga chitetezo cha 100% stator grounding.Chitetezo chili ndi PT wire break lock.

Kutembenuka kwa Stator kutembenuza chitetezo cha jenereta

Chitetezo chimapangidwa ndi ma voliyumu aatali a zero-sequence voltage ndi njira yotsatizana yolakwika ya gulu la zolakwika.Muyeso wa kutsekereza kwa PT umayikidwa ngati chitetezo chachikulu chapakati-kutembenukira, pakati-gawo lalifupi dera ndi stator yokhotakhota kutsegula kuwotcherera mkati mwa jenereta.Cholakwika chigawo cholakwika chotsatira chizindikiritso chotsatira cha zero chautali chimazindikira kutulutsa kwautali kwa 3U0 ndi 3PT yotsegulira makona atatu yomwe imalumikizidwa mwachindunji ndi jenereta yopanda ndale koma osakhazikika pozindikira mphamvu yotsatizana ya jenereta.Chitetezo chimayima konse.

Wopanga ma jenereta chitetezo chakunja

Chitetezo chimagwiritsa ntchito zinthu zitatu za impedance, kudzera pakusintha kwa njira ya impedance kuti izindikire kuchuluka kwa mtengo wotsetsereka ndikuzindikira komwe kuli oscillation center.Pankhani ya vuto lalifupi, kusokonezeka kwa dongosolo, kupuma kwamagetsi, etc., chitetezo ku misoperation.Guard zochita zambiri pa chizindikiro;Pamene oscillation likulu lili mkati mwa jenereta ndi thiransifoma gulu, gawo chitetezo ndikuyamba kutumiza tripping lamulo kudzera T1 (0.5s), ndi zochita ndi zimitsani mphamvu maginito.Pamene malo oscillation ali kunja kwa jenereta-transformer seti, gawo la chitetezo II limayambitsidwa kuti liwonetsere kudzera mu T2 (2S).Chitetezo chimakhala ndi chipangizo chotsekera chamakono kuti chiwonetsetse kuti zamakono sizikupitirira zomwe zimayikidwa kunja kwa sitepe yowonongeka kwa woyendetsa dera pamene wodutsa dera watsekedwa.

Low pafupipafupi accumulative chitetezo

Kuchepa kwafupipafupi kumadzikundikira chitetezo kachitidwe pafupipafupi kuti muchepetse kuchuluka kwa mphamvu ya turbine ya nthunzi, chitetezo chimapangidwa ndi ma frequency frequency relay ndi kauntala, kutseka zolumikizira zolumikizirana ndi zolumikizira (ndiko kuti, jenereta yocheperako yotuluka nthawi yolumikizira chitetezo komanso kusiya kuthamanga), ma frequency system owonjezera amakhala otsika kuposa 47.5 Hz nthawi yokhazikitsa nthawi, pomwe mitengo yokhazikika yanthawi yonse mpaka masekondi a 3000, Signal idzatumizidwa pakachedwa masekondi 30.Chipangizocho chikhoza kuyang'aniridwa mu nthawi yeniyeni panthawi yogwira ntchito: mtengo wokhazikika, pafupipafupi F ndi nthawi yochuluka yowonetsera.Chitetezo chosiyana cha jenereta ndi gulu la thiransifoma, chitetezo chosiyana cha thiransifoma ndi chitetezo chosiyana kwambiri ndi chitetezo chachikulu cha interphase yochepa dera cholakwika cha zigawo zotetezedwa, pogwiritsa ntchito chiŵerengero cha kuphulika.Kulakwitsa kwakunja kwa zone kumatha kupeweratu kusakhazikika komwe kumachitika chifukwa cha kusagwirizana kwa mawonekedwe a CT mbali iliyonse, ndipo chitetezo cham'derali chimatha kuchitapo kanthu movutikira.Pofuna kupewa misoperation chitetezo pansi thiransifoma inrush panopa, chitetezo amatengera chachiwiri harmonic lokhoma.Chitetezo chimakhala ndi ntchito yotsekereza kuthamanga kwa masiyanidwe popanda funde lachiwiri la harmonic, ndipo cholakwikacho chimatha kuchotsedwa nthawi yomweyo pomwe kusiyanasiyana kumafika pamtengo wokhazikika.Chitetezo chili ndi ntchito yotsekera mzere wa CT (osagwiritsidwa ntchito kwenikweni).Tsankho la CT line break ndilofanana ndi chitetezo cha kusiyana kwa jenereta.

Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. unakhazikitsidwa mu 2006, ndi Mlengi wa jenereta dizilo ku China, amene integrates kamangidwe, kupereka, kutumiza ndi kukonza dizilo jenereta seti.Zogulitsa zimaphatikizapo Cummins, Perkins, Volvo, Yuchai, Shangchai, Deutz , Ricardo, MTU, Weichai etc. ndi mphamvu osiyanasiyana 20kw-3000kw, ndi kukhala OEM fakitale ndi pakati luso.
