Ua rau Undervoltage ntawm Cummins Generator Teeb

Niaj hnub no, nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, qhov tsis txaus ntawm txhua yam khoom siv tau raug daws.Pa Cummins generators, piv txwv li, tsuas yog siv tau rau hauv cov tsheb loj thiab nruab nrab.Qhov no feem ntau yog vim lub tshuab hluav taws xob ib txwm teeb tsa ntim, loj, suab nrov, kev vibration yog vim li cas, yog li ntawd nws lub zog ntsuas tsis zoo li roj av cav, yog li kev siv Cummins generator teeb yog txwv rau ntau yam me me.Nrog rau kev qhia txog kev siv thev naus laus zis, cov tsoos Cummins generator teeb tau zoo heev, cov kev tsis txaus siab uas twb muaj lawm kuj tau zoo heev, kev nce qib ntawm cov thev naus laus zis tshiab, yog li ntawd. cummins generator teeb daim ntawv thov Scope tseem txhawb nqa.

【Common Cummins generator teem tsis ua hauj lwm tsom xam】

1. Tswj cov hlau tsis ua hauj lwm los yog xoob, kev daws teeb meem: xyuas tswj cov xaim kho lossis xauv.

2. pib lub cev muaj zog tsis ua hauj lwm, kev daws teeb meem: hloov lub pib lub cev muaj zog.

3. Lub tshuab hluav taws xob diesel pib pib tsis raug.Kev daws: Pib raws li cov lus qhia.

4. Cav pib relay tsis ua hauj lwm, kev daws teeb meem: hloov qhov pib relay.

5. diesel generator pib / nres hloov tsis ua haujlwm, kev daws teeb meem: hloov qhov pib nres hloov.

6. diesel generator pib lub cev muaj zog auxiliary hluav taws xob txhais lus yuam kev, kev daws teeb meem: hloov pib lub cev muaj zog pab txhais lus hluav taws xob.

【Common Cummins generator teeb undervoltage tsom xam】

1. Cov txheej txheem ceev ceev ntawm Cummins generator teeb

Lub tshuab hluav taws xob ceev tswj cov ntsiab lus, hluav taws xob ceev tswj thiab cov neeg kho tshuab tswj, yog tias nws yog ib qho kev tswj xyuas kev ceev, tom qab ntawd ntawm lub tshuab hluav taws xob teeb muaj kev tswj cov roj thiab cov roj twj tso kua mis lub cev, zoo li hu ua lub twj tso kua mis twj tso kua mis, uas muaj tus pas nrig rub, yog tswj cov roj, hu rau nws ceev regulating pas nrig, ceev regulating pas nrig ceev (siab ceev) ntawm ob sab ntawm lub tis ntawm ib tug plunger plunger thiab ceev tswj, switched rau 20 s yog tsis tshua muaj voltage, kuv tsis paub seb qhov voltage thiab zaus muaj. tsis tau nce, yog tias nws tsis tau nce, nws yuav tshwm sim los ntawm qhov ceev tsis nce, koj tuaj yeem kho tus pas nrig ceev kom sim, thaum twg lub tshuab hluav taws xob pab pawg tsis ua haujlwm, feem ntau muaj qhov txhaum loj, qhov txhaum loj tau daws, thiab ib tug series ntawm lwm yam txhaum tshwm sim los ntawm nws yuav raug daws.

2, kev xav

Yog tias lub tshuab hluav taws xob tsis muaj qhov tsis zoo, qhov hluav taws xob ntawm lub tshuab hluav taws xob tsis tuaj yeem tsim thaum pib.Rau qhov teeb meem no, peb yuav tsum paub ntau npaum li cas V voltage qhov excitation tso zis ntawm lub tshuab hluav taws xob AVR voltage regulator yog, thiab ces txuas tus coj voltage qhov chaw ntawm lub excitation tso zis kab rau magnetization (lub voltage hom yuav tsum sib xws, thiab lub polarity yuav tsum tsis txhob. rov qab).

3. Cov kab ntsuas hluav taws xob yog xoob

Qhov no yog ib qho yooj yim to taub, qhov voltage sampling kab yog xoob, uas yuav tsum tsis muaj peev xwm ntsuas qhov voltage.

4. Siab tswj phaj tsis ua hauj lwm

Vim yog qhov hloov pauv ntawm ib puag ncig, qhov tsis sib xws ntawm AVR adjustable clamp yog tsis siv ntxiv lawm, yuav tsum tau kho, feem ntau, txoj kev weaver generator yeej tsis tshwm sim qhov teeb meem no, vim hais tias cov tsis muaj adjustable clamp yog tsau. tus nqi (400 v), feem ntau peb kho tau, tsuas yog siv rau weaver chav tsev yuav tshwm sim qhov teeb meem no, Vim hais tias nyob rau hauv AVR adjustable clamp thiab tshuab yog kho raws li lub ntsiab tsheb npav-bar voltage, nws tsis zoo li qub, lub sij hawm no, cov khoom siv weaver feem ntau muaj lub siab tswj lub teeb liab rau hauv AVR adjustable clamp, qhov xwm txheej zoo li no lossis xyuas cov teeb liab tswj yog tias muaj qhov tsis ncaj ncees lawm, lossis sim khau raj sai siv cov khoom siv hluav taws xob tswj (weaver, adjustable clamp, thiab lwm yam) pib dua voltage.

5. Kev ua txhaum hauv av

Yog hais tias cov kab yog peb-theem grounded, ces qhov voltage thiab tam sim no muaj tsawg heev, lub sij hawm no mus xyuas lub grounding discharge ntaus ntawv (xws li av riam) tsis raug kaw los yog grounded.

6, lub tshuab hluav taws xob winding varistor lossis rectifier choj diode puas

Lub varistor overvoltage txhaum tshwm sim varistor conduction nrog kauj ruam-down, tawg los yog rau lwm yam yog vim li cas yog lub varistor yog conduction, yog li nws yog conceivable tias voltage yog tsawg heev, muaj rau diode rectifier choj, teeb tsa ntawm dc zog los muab adjustable clamp thiab excitation ntaus ntawv, xws li yog hais tias tus diode rectifier choj puas, adjustable clamp thiab cov nyhuv ntawm excitation ntaus ntawv xws li yuav luv nqi.
