Symmetric Overload Chitetezo Kwa Genset

Kutetezedwa kwafupipafupi kudzikundikira

Chitetezo chochepa chafupipafupi chimawonetsa kuchuluka kwa kuchepetsedwa kwa ma frequency a system pa turbine.Chitetezo chimapangidwa ndi ma frequency frequency relay ndi counter, otsekedwa ndi kulumikizidwa kothandizira kwa chowombera chotuluka (ndiko kuti, jenereta ikasiya kugwira ntchito, chitetezo chocheperako chimasiyanso kuthamanga).Pamene ma frequency accumulative system ali otsika kuposa kuchuluka kwa ma frequency a 47.5Hz, nthawi yochulukirapo ikafika pamtengo wokhazikika wa masekondi a 3000, chochitacho chidzatumiza chizindikiro chochedwa masekondi 30.Chipangizocho chikhoza kuyang'aniridwa mu nthawi yeniyeni panthawi yogwira ntchito: mtengo wokhazikika, pafupipafupi F ndi nthawi yochuluka ikuwonetsedwa.Kutetezedwa kosiyana kwa thiransifoma ya jenereta, chitetezo chosiyana cha thiransifoma ndi chitetezo chosiyana cha thiransifoma wapamwamba kwambiri ndiye chitetezo chachikulu ku vuto la interphase lalifupi la zigawo zotetezedwa.Pakakhala vuto lakunja, kusalinganika komwe kumachitika chifukwa cha mawonekedwe osagwirizana a CT mbali iliyonse kumatha kupewedwa modalirika, ndipo chitetezo cham'derali chimakhala ndi zochitika zovuta.Pofuna kupewa misoperation chitetezo pansi thiransifoma inrush panopa, chitetezo amatengera chachiwiri harmonic lokhoma.Chitetezo chimakhala ndi ntchito yochotsa masiyanidwe apano popanda kutseka ma harmonic achiwiri.Kusiyana kwamakono kukafika pamtengo wokhazikitsidwa, cholakwikacho chimachotsedwa nthawi yomweyo.Chitetezo chili ndi ntchito yotsekera mzere wa CT (osagwiritsidwa ntchito kwenikweni).Tsankho la CT line break ndilofanana ndi chitetezo cha kusiyana kwa jenereta.

Chisangalalo wozungulira mochulukira chitetezo

Chitetezo chowonjezera cha loop chimagwiritsidwa ntchito pachitetezo chotsitsimula cha rotor chomwe chikudutsa pano kapena chitetezo chochulukirapo, chomwe chimagawidwa m'magawo atatu, okhala ndi nthawi yokhazikika komanso nthawi yosiyana.

Zomwe zikuchitika pa gawo la nthawi yokhazikika zimayikidwa molingana ndi momwe zingabwerere modalirika pansi pa zomwe zidavotera zomwe zikuchitika.Zimagwira ntchito pa chizindikirocho ndipo zimachepetsa chisangalalo chamakono pambuyo pa nthawi ya T1 (5s) (zotsatira zochepetsera mphamvu zowonongeka ndizopanda ntchito);Mchitidwe wa malire a nthawi yosiyana umatsimikiziridwa molingana ndi kuchuluka kwa mafunde othamangitsa jenereta, ndipo chitetezo ndikuyimitsa sitima.Nthawi yowerengera yowerengera ndi masekondi 10.

Chitetezo choyambira cha jenereta cha rotor

Kutetezedwa kwa mfundo imodzi ya rotor ya jenereta kumagwiritsidwa ntchito kuwonetsa kulakwitsa kwa mfundo imodzi ya dera la jenereta.Chitetezo chimagwiritsa ntchito mfundo yosinthira ping-pong.Mpweya wabwino ndi woipa wa dera la rotor kupita pansi umayesedwa motsatizana, ndipo kukana kwa rotor grounding ndi malo oyambira kumawerengeredwa mu nthawi yeniyeni pothetsa ma equation awiri osiyana oyambira.Pambuyo pa kuchedwa kwa 2 masekondi, mlonda amagwiritsa ntchito chizindikiro.

Symmetric overload chitetezo kwa jenereta

Chipangizo chotetezera chimakhala ndi malire a nthawi yokhazikika komanso malire a nthawi.Gawo la nthawi yokhazikika masekondi 5 chizindikirocho chikagwiritsidwa ntchito.Mawonekedwe a nthawi yosinthira amatsimikiziridwa molingana ndi mphamvu ya jenereta kuti ipirire mochulukira, ndipo zomwe zimachitika ndikuthetsa vutoli.Chipangizo chotetezera chimatha kuwonetsa njira yosungiramo kutentha kwa stator ya jenereta.

Kutetezedwa kochulukira kwa ma jenereta osatsatana bwino

Chipangizo chotetezera chimakhala ndi malire a nthawi yokhazikika komanso malire a nthawi.Nthawi yokhazikika yochitapo kanthu pakali pano imayikidwa molingana ndi ndondomeko yolakwika yamtengo wapatali yomwe jenereta imalola kwa nthawi yaitali komanso mtengo wamakono kuti mupewe kusagwirizana kwa zosefera zomwe zikuchitika panopa pansi pa katundu wambiri, ndipo zimagwiritsidwa ntchito pa chizindikiro pambuyo pa 3- malire a nthawi yachiwiri.Mawonekedwe a nthawi yosinthira amatsimikiziridwa molingana ndi kuthekera kwa jenereta kupirira motsatana molakwika pakali pano, ndipo zomwe akuchita ndikuthetsa demagnetization.Chipangizo chotetezera chimatha kuwonetsa njira yosungiramo kutentha kwa rotor ya 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, Shanghai, Deutz, Ricardo, MTU, Weichai etc. ndi mphamvu osiyanasiyana 20kw-3000kw, ndi kukhala OEM fakitale ndi pakati luso.
