Chikonzero cheUndervoltage yeCummins Jenareta Seti

Mazuvano, nekufambira mberi kwesainzi uye tekinoroji, kukanganisa kwemarudzi ese emidziyo kwakagadziriswa.Akajairika Cummins jenareta, semuenzaniso, anogona kungoshandiswa mumarori makuru uye epakati.Izvi zvinonyanya nekuti chinyakare jenareta set vhoriyamu, bulky, ruzha, vibration zvikonzero zvakakwirira, kuitira kuti simba rayo indekisi haina kunaka sezvo peturu injini, kuti kushandiswa Cummins jenareta set inogumira kune diki chaizvo siyana.Nekuunzwa kwehunyanzvi hwepamusoro, iyo yechinyakare Cummins jenareta seti yakagadziridzwa zvakanyanya, zvikanganiso zviripo zvakavewo mhinduro yakanaka kwazvo, kuenderera mberi kwehunyanzvi hwekuvandudza tekinoroji, zvekuti cummins jenareta set application scope inoramba ichisimudzira.

【Yakajairwa Cummins jenareta kuseta kutadza kuongororwa】

1. Kudzora kutadza kwetambo kana kusunungura, mhinduro: chengetedza kudzora wire kugadzirisa kana kuvhara.

2. kutanga mota kutadza, mhinduro: tsiva mota yekutanga.

3. Dizeli generator set inotanga zvisina kunaka.Mhinduro: Tanga maererano nemirairo.

4. Injini yekutanga relay kukundikana, mhinduro: tsiva yekutanga relay.

5. dizeli jenareta kutanga / kumisa kushandura kukundikana, mhinduro: shandura iyo yekutanga stop switch.

6. dhiziri jenareta tanga mota yekubatsira magetsi ekushandura kukanganisa, mhinduro: tsiva yekutanga mota yekubatsira emagetsi shanduro.

【Yakajairwa Cummins jenareta set undervoltage analysis】

1. Iyo mechanical speed regulation yeCummins generator set

Jenareta kukurumidza kudzora mapoinzi, yemagetsi kumhanya kudzora uye mechanical control, kana iri mechanical kumhanya mutemo, ipapo pane jenareta seti ine kutonga kwemafuta nemafuta pombi muviri, inoita kunge inonzi common rail pombi, ine tsvimbo yekudhonza, ndeye dzora oiri, idaidze kumhanya kwetsvimbo yekudzora, kumhanya inodzora tsvimbo (yakakwira) mativi ese ekugoverwa kweplunger plunger uye kumhanya kudzora, yakabatidzwa pa20 s yakaderera voltage, handizive kana voltage uye frequency ine. isati yasimuka, kana isati yasimuka, inogona kukonzerwa nekumhanya kusati kwakwira, unogona kugadzirisa tsvimbo yekumhanyisa kuti uedze, pese pakakundikana boka rejenareta, kazhinji pane mhosva huru, mhosva huru inogadziriswa, uye mutsara wezvikanganiso zvechipiri zvinokonzerwa nazvo zvichagadziriswa.

2, remanence

Kana jenareta isina remanence, iyo voltage system yejenereta haigone kuvakwa pakutanga.Nekuda kwedambudziko iri, isu tinofanirwa kuziva kuti yakawanda sei V voltage iyo excitation inobuda yejenareta AVR voltage regulator, tobva tabatanidza inoenderana voltage sosi pane excitation inobuda mutsara wemagnetization (iyo voltage rudzi inofanirwa kuenderana, uye iyo polarity haifanirwe. be reversed).

3. Iyo voltage sampling line yakasununguka

Izvi zviri nyore kunzwisisa, iyo voltage sampling line yakasununguka, iyo haifanirwe kukwanisa kuyera voltage.

4. Dzvinyiriro inodzora ndiro kukundikana

Nekuda kwekuchinja kwemamiriro ekunze, iyo paramita yeAVR inogadziriswa clamp haichashande, inoda kugadzirisa, kazhinji, iyo weaver jenareta nzira haizoratidzike rudzi urwu rwedambudziko, nekuti maparamendi eiyo inogadziriswa clamp yakagadziriswa. kukosha (400 v), kazhinji isu tinochinjika, inongoshandiswa kuruka yuniti inogona kuoneka rudzi urwu rwedambudziko, Nekuti muAVR inogadziriswa simbi uye muchina unogadziriswa zvinoenderana neiyo huru bhasi-bar voltage, haina kumira, panguva ino, midziyo yevaruki kazhinji ine dhizaini inodzora chiratidzo muAVR inogadziriswa clamp, rudzi urwu rwemamiriro kana kutarisa chiratidzo chekudzora kana paine chakaipa, kana edza bhutsu nekukurumidza uchishandisa magetsi ekudzora mudziyo (weaver, inogadziriswa clamp, nezvimwewo) reset voltage.

5. Kukanganisa

Kana iyo mutsara wakadzikwa-nhatu, ipapo voltage uye ikozvino yakaderera zvikuru, ino nguva yekutarisa chigadziro chekudzikisa pasi (senge banga repasi) haina kuvharwa kana kuiswa pasi.

6, jenareta inotenderedza varistor kana rectifier bhiriji diode kukuvara

Iyo varistor overvoltage kukanganisa kunoitika varistor conduction ine nhanho-pasi, kuputsika kana zvimwe zvikonzero kana varistor iri conduction, saka zvinofungidzirwa kuti voltage yakadzikira kwazvo, kune matanhatu diode rectifier bhiriji, kuseta kweiyo dc simba rekupa inogadziriswa clamp uye mudziyo wekusimudzira, wakaita senge diode rectifier bhiriji kukuvadzwa, chinobatika chinobatika uye mhedzisiro yemudziyo wekunakidza senge uchaderedzwa.
