Tsom xam cov yam ntxwv thiab kev ua haujlwm ntawm Generator Sib Piv Txwv
Nrog kev lag luam ntawm kev lag luam, qhov peev xwm ntawm cov khoom siv hluav taws xob tau txais kev loj dua thiab loj tshaj, thiab yuav tsum muaj ntau tshaj qhov kev tso tawm rau kev ua haujlwm tiv thaiv kev tiv thaiv. Lub hauv paus kev ruaj ntseg ntawm kev tiv thaiv kev ruaj ntseg yog raws li kev to taub meej ntawm txoj cai txhaum. Ntxiv kev txhim kho kev kawm ntawm kev tiv thaiv lub ntsiab ntawm cov loj generators yuav tsum muaj kev nkag siab zoo thiab kev nkag siab ntau ntawm cov teeb meem sab hauv ntawm lub tshuab hluav taws xob. Nyob rau hauv txoj kev nkag siab tob ntawm qhov txhaum ntawm lub tshuab hluav taws xob, nws muaj peev xwm los tawm tswv yim thiab txhim kho qhov kev tiv thaiv tseem ceeb ntawm lub tshuab hluav taws xob raws li cov yam ntxwv txhaum, thiab muaj kev zoo siab thiab txhim kho lub ntsiab kev tiv thaiv ntawm lub tshuab hluav taws xob.
Generator sib txawv tiv thaiv
Ib qho tseem ceeb ntawm cov cuab yeej hluav taws xob tiv thaiv yog qhov ua yuam kev los yog lwm yam kev txawv txav sab nraud ntawm qhov chaw tiv thaiv yuav tsum ruaj khov thiab txhim kho, thiab yuav tsum tsis txhob ua txhaum. Lub DG2 generator kev tiv thaiv relay tag nrho raws li saum toj no yuav tsum tau thiab yog tau txais los ntawm cov neeg siv.
Qhov yooj yim DG2 relay tseem muaj peev xwm yuav nruab nrog cov ntawv luam ntxiv Circuit Board rau ntxiv cov kev ua haujlwm. Los ntawm kev siv cov txheej txheem tshiab rau cov hom kev lag luam tam sim no, qhov kev txuas yuav txiav txim siab tias cov qauv hluav taws xob tam sim no muaj qhov teeb meem ntawm sab hauv los yog sab nraud nyob hauv thaj chaw tiv thaiv, yog li txiav txim siab tias cov tshuab hluav taws xob tsis ua hauj lwm los yog tswj cov haujlwm ruaj khov. Qhov kev ua kom zoo dua qub (DG2-Sat) yog qhov tshwj xeeb tshaj yog rau kev tiv thaiv cov tseem ceeb generators lossis cov generators nrog cov nqi siab tsis ua haujlwm hauv cov fais fab.
Nyob rau hauv rooj plaub ntawm luv-circuiting nruab nrab ntawm stator windings ntawm generator thiab nws cov hlau plhaws tawm, thaiv sib txawv ntev yuav tsum raug ntsia.
Raws li txoj kev thaiv thiab txoj hauj lwm, nws muaj peev xwm raug muab faib ua txhua yam kev sib txawv ntawm longitudinal thiab tsis tiav lengthwise txawv. Qhov sib tshuam ntawm kev sib txawv ntawm kev sib txawv yog qhov kev tiv thaiv thawj zaug rau lub sij hawm luv-mus-theem luv-Circuit fault ntawm generator. Tsab ntawv teev npe ntawm kev tiv thaiv sib txawv raws li kev tiv thaiv kev tiv thaiv theem-rau-theem luv-kev tiv thaiv muaj keeb kwm ntev tshaj plaws. Thawj qhov uas tib neeg ua tom qab digital technology yog cov kev tiv thaiv cov kev tshawb fawb ntev. Tom qab muaj kev tiv thaiv zoo sib txawv raws li kev tshoov siab ntawm qhov sib txawv ntawm qhov kev npaj siab, tus tswv yim rau kev xam phaj tam sim no ntawm lub tshuab hluav taws xob kawg thiab qhov nruab nrab ntawm qhov siv cov kev sib raug zoo ntawm txoj kev xav kom paub sib txawv ntawm kev tiv thaiv, thiab cov sib luag proportional lossis Qhov sib txawv sib txuam tam sim no qhov kev sib tsoo ntawm tus nplhaib rau kev ua ntau yam, uas ua tau zoo dua selectivity thiab rhiab heev rau cov khoom siv nrog ib kauj fais fab. Txhawm rau tshem tawm tus cawv ntawm cov khoom thauj khoom thiab ntxiv txhim kho lub zog, kev tivthaiv kev tivthaiv ploj yog siv los txhim kho cov qauv kev tiv thaiv kabmob.
Txij li cov kev tiv thaiv kab ke txawv no tsuas yog siv tau rau theem ntawm theem rau-theem luv luv ntawm cov generator thiab nws ua rau, qhov ua haujlwm yog nqaim. Nyob rau hauv xyoo tas los, ib qho kev tiv thaiv tsis tiav txawv teb chaws tau npaj tawm txawv teb chaws, thiab nws tau pib siv rau hauv cov hydraulic loj loj. Lub hauv paus ntsiab lus ntawm kev tiv thaiv sib txawv yog mus txuas rau nruab nrab ntawm qhov chaw nruab nrab ntawm kev tiv thaiv kab mob sib txawv rau cov theem sib txuas ntawm cov kab sib txuas ntawm txhua theem, qhov no nthuav tawm kev tiv thaiv rau theem-rau-theem, kev luv luv luv luv thiab ceg qhib vuam . Ib qhov kev tiv thaiv tshiab uas ua haujlwm. Tau kawg, qhov kev ua haujlwm no yog nyob ntawm cov nuj nqis ntawm kev ua kom zoo li qub, uas yog rau cov theem-rau-theem lossis kev sib tw luv luv hauv qee qhov chaw, qhov tsis zoo ntawm qhov kev tiv thaiv tsis tiav yog yuav qis tshaj qhov qhov kev tiv thaiv sib txawv los sis lateral txawv. Tsis tas li ntawd, qhov tseem ceeb ntawm qhov txawv ntawm qhov tsis sib xws tam sim no tseem nyuaj, thiab nws tseem muaj qhov teeb meem ntawm TA installation.
Cov kev ntsuas los txhim kho qhov rhiab qhov sib txawv ntawm kev sib tiv thaiv tsuas yog muaj ob yam:
(1) Tsawg kom tsawg dua qub. Qhov no suav nrog xaiv TA nrog tib yam ntxwv zoo li tau. Piv txwv, xaiv TA rau kev tiv thaiv sib txawv ntawm tus qauv tib yam thiab txo lub nra ntawm lub hauv paus loj.
(2) Txhim kho cov yam ntxwv ua haujlwm ntawm kev tiv thaiv sib txawv. Tam sim no, qhov sib txawv ntawm kev tiv thaiv nrog txoj kab-kev txhuam tus cwj pwm siv dav dav siv hauv qhov ntev chav tsev tiv thaiv ntawm cov koog loj loj, yog li ntawd lub zog coefficient thiab braking yam ntxwv zoo zoo tuaj tib lub sijhawm.
Kev tiv thaiv ntawm lub tshuab hluav taws xob stator thiab nws cov hluav taws xob-theem-rau-theem luv-qhov teeb meem muaj cov teeb meem nram qab no:
(1) Nws muaj cov yam ntxwv ntawm kev sib to taub thiab kev sib txuam nrog kev tiv thaiv kom tsis txhob ua txhaum ntawm qhov teeb meem sab nraud, tiv thaiv kom tsis txhob siv lub tshuab ua hluav taws xob thaum lub sij hawm ntev dhau lawm.
(2) Thaum twg tam sim no transformer raug kaw, ib lub teeb liab tsocai tau.
(3) Thaum muaj teeb meem ntawm ob sab hauv tib theem (tawm ntawm ib cheeb tsam, sab nraud me ntsis), qhov tawm tau.
(4) Qhov chaw thaj tsam ntawm kev khiav hauj lwm tam sim no yog 0.1 mus rau 1.0 npaug ntawm cov nqi tam sim no.
(5) Lub sij hawm ua haujlwm (thaum lub sijhawm tam sim no yog ob zaug) tsis pub tshaj 30 xuab moos.
(6) Tom qab tiv thaiv kev tiv thaiv sib txawv, qhov kev tiv thaiv kev tiv thaiv hluav taws xob tiv thaiv tawm 1 kev siv tawm kev siv tawm.
