Lub luag haujlwm tiv thaiv kev tiv thaiv thiab kev ntsuas tsis zoo thiab xaiv

Lub luag haujlwm thiab kev ntsuas tsis raug ntawm kev tiv thaiv kev tiv thaiv

Cov cuab yeej tiv thaiv hluav taws xob kuj tseem hu ua cov cuab yeej txuas hluav taws xob, tiv thaiv hluav taws xob ntau dhau, tiv thaiv hluav taws xob, tiv thaiv hluav taws xob, tiv thaiv hluav taws xob, thiab lwm yam. Cov cuab yeej tiv thaiv hluav taws xob siv rau tiv thaiv kab hluav taws xob hu ua lub zog tiv thaiv hluav taws xob. Hauv kev pom ntawm cov yam ntxwv tam sim no ntawm kev puas tsuaj hluav taws xob, kev tiv thaiv hluav taws xob tshwj xeeb tshaj yog nyob rau hauv kev hloov kho ntawm kev tiv thaiv xob laim, thiab cov phiaj xwm tiv thaiv raws li kev tiv thaiv xob laim yog qhov yooj yim tshaj plaws thiab kev lag luam tiv thaiv hluav taws xob zoo tshaj plaws. Lub luag haujlwm tseem ceeb ntawm tus ntes hluav taws xob yog khaws lub peev xwm ntawm ob qho kawg ntawm nws zoo ib yam lossis hauv ib puag ncig thaum lub sijhawm tshwm sim tshwm sim, thiab hloov pauv lub zog ntau dhau ntawm tus neeg xyuas pib nquag.

mus rau hauv qhov tso tawm hauv av, yog ib feem tseem ceeb ntawm kev ua kom muaj hluav taws xob sib npaug thiab muaj kev sib txuas zoo sib xws. Qee qhov kev ntsuas tseem ceeb ntawm kev ntsuas hluav taws xob: ntsuas qhov ua haujlwm voltage, ntsuas ua haujlwm tam sim no, thiab muaj peev xwm nqa tau qhov tshwj xeeb pom zoo series-parallel fais fab tua hluav taws. Lub peev xwm tam sim no, kev muaj peev xwm ntawm tus ntes hluav taws xob tuaj yeem hloov qhov hluav taws xob tam sim no, hauv kiloamps (KA), cuam tshuam nrog hom qhib nthwv dej. Hais txog kev ua haujlwm, cov cuab yeej tiv thaiv hluav taws xob tuaj yeem faib ua cov khoom tiv thaiv hluav taws xob uas tuaj yeem tiv thaiv hluav taws xob ncaj qha thiab cov cuab yeej tiv thaiv hluav taws xob uas tuaj yeem tiv thaiv xob laim. Cov tiv thaiv hluav taws xob uas tuaj yeem tiv thaiv hluav taws xob ncaj qha feem ntau yog siv rau kab kev tiv thaiv uas tuaj yeem raug hluav taws xob ncaj qha, xws li kev tiv thaiv ntawm kev sib tshuam ntawm LPZOA thiab LPZ1 thaj chaw. Siv 10/35μs qhov kev hloov pauv tam sim no los ntsuas thiab qhia nws lub peev xwm tam sim no. Cov tiv thaiv hluav taws xob tiv thaiv hluav taws xob feem ntau yog siv rau kev tiv thaiv kab uas tsis tuaj yeem raug hluav taws xob ncaj qha, xws li kev tiv thaiv ntawm kev sib tshuam ntawm thaj chaw LPZOB, thaj tsam LPX1, thiab thaj tsam LPZ1. 8/20μs cov qauv nthwv dej tam sim no tau siv los ntsuas thiab qhia lub sijhawm teb ntawm nws lub peev xwm txaus. Lub sijhawm xav tau rau lub teeb hluav taws xob tuaj yeem tswj qhov tshwm sim tsis tu ncua yog cuam tshuam nrog qhov xwm txheej ntawm cov nthwv dej. Qhov seem hluav taws xob, qhov muaj peev xwm txwv qhov muaj peev xwm ntawm cov hluav taws xob ntes rau qhov tshwm sim tsis tu ncua, muaj feem cuam tshuam nrog qhov dav ntawm qhov hluav taws xob tam sim no thiab qhov zoo ntawm cov nthwv dej.

Xaiv cov cuab yeej tiv thaiv xob laim

Yog tias koj xav kom ua tiav cov txiaj ntsig zoo raws li kev tiv thaiv ntawm cov neeg tua hluav taws xob, koj yuav tsum tau mloog zoo rau&"; tsim nyog ntes hluav taws xob raug qhov chaw raug &". Kev xaiv cov ntes hluav taws xob yog qhov tseem ceeb heev.

1. Kev faib hluav taws xob tam sim no ntawm ntau qhov chaw nkag mus rau hauv lub tsev yog raws li hauv qab no: kwv yees li 50% ntawm cov hluav taws xob tam sim no xau mus rau hauv av los ntawm cov cuab yeej tiv thaiv hluav taws xob sab nraud, thiab lwm 50% ntawm qhov hluav taws xob tam sim no yuav nyob hauv cov khoom siv hlau tag nrho cov system Ua ib txoj haujlwm. Hom kev ntsuas no yog siv los kwv yees lub peev xwm tam sim no thiab cov xov hlau tshwj xeeb ntawm cov neeg tua hluav taws xob uas muaj peev xwm txuas nrog ntawm kev sib tshuam ntawm LPAOA, LPZOB thiab LPZ1. Qhov hluav taws xob tam sim no ntawm no yog 10/350μs qhov nthwv dej tam sim no. Nyob rau hauv rooj plaub ntawm kev faib hluav taws xob tam sim no hauv txhua cov khoom siv hlau: qhov dav ntawm txhua feem ntawm qhov hluav taws xob tam sim no nyob ntawm qhov tsis cuam tshuam thiab inductance ntawm txhua txoj kev faib khoom. Kev faib khoom xa mus hais txog cov khoom siv hlau uas tuaj yeem xa mus rau qhov hluav taws xob tam sim no, xws li cov kab hluav taws xob, kab teeb liab, Cov yeeb nkab-qib thiab lwm yam hauv av xws li cov kav dej, cov hlau thav duab, thiab lwm yam, feem ntau tuaj yeem kwv yees kwv yees tsuas yog los ntawm lawv cov kev sib tw hauv av tseem ceeb. Hauv qhov xwm txheej tsis paub tseeb, nws tuaj yeem txiav txim siab tias qhov kev tawm tsam ntawm kev sib txuas sib npaug, uas yog, txhua lub raj xa hlau sib faib tam sim no sib npaug.

2. Thaum cov kab hluav taws xob tau tshaj tawm ua ntej, thiab cov kab hluav taws xob tuaj yeem raug tsoo los ntawm xob laim ncaj qha, qhov hluav taws xob tam sim no nkag mus rau thaj chaw tiv thaiv hauv lub tsev yog nyob ntawm qhov cuam tshuam thiab inductance ntawm cov kab sab nraud, lub teeb hluav taws xob tso tawm thiab neeg siv kab sab. Yog tias sab hauv thiab sab nrauv tsis zoo ib yam, cov kab hluav taws xob tau faib ib nrab ntawm cov hluav taws xob ncaj qha tam sim no. Hauv qhov no, tus tiv thaiv hluav taws xob nrog lub luag haujlwm ntawm kev tiv thaiv hluav taws xob ncaj qha yuav tsum tau siv.

3. Hom kev tshuaj xyuas tom ntej yog siv los ntsuas qhov kev faib hluav taws xob tam sim no ntawm kev sib tshuam ntawm thaj chaw tiv thaiv tom qab thaj tsam LPZ1. Txij li qhov kev tiv thaiv hluav taws xob tsis zoo ntawm cov neeg siv sab yog ntau dua li qhov cuam tshuam ntawm cov ceg tso tawm ntawm cov hluav taws xob ntes thiab cov kab hluav taws xob sab nraud, cov hluav taws xob tam sim no nkag mus rau thaj tsam tiv thaiv xob laim tom ntej yuav raug txo, thiab tsis muaj kev kwv yees tshwj xeeb yuav tsum tau hais txog tus nqi. Nws feem ntau xav tau tias lub peev xwm ntws tam sim no ntawm lub zog tiv thaiv hluav taws xob tau siv hauv cheeb tsam tiv thaiv xob laim tom ntej yog qis dua 20kA (8/20μs), thiab nws tsis tas yuav siv tus tiv thaiv kev tiv thaiv nrog lub peev xwm loj tam sim no.

Kev xaiv tom ntej ntawm thaj chaw tiv thaiv hluav taws xob tiv thaiv hluav taws xob yuav tsum xav txog kev faib hluav taws xob thiab kev sib koom ua ke ntawm txhua qib. Thaum muaj ntau yam nyuaj los txiav txim siab, kev siv cov khoom siv hluav taws xob sib txuas hluav taws xob tiv thaiv hluav taws xob yog qhov kev xaiv zoo. Serial-parallel yog lub tswv yim uas tau hais tawm raws cov yam ntxwv ntawm ntau daim ntawv thov hauv kev tiv thaiv hluav taws xob niaj hnub no thiab kev faib tawm ntawm cov kev tiv thaiv kab ke (piv rau cov tsoos ib txhis xob ntes hluav taws xob). Nws lub ntsiab lus yog kev sib xyaw ua ke ntawm ntau theem ntawm tus neeg ntes thiab lim tshuab los ntawm kev sib koom ua zog thiab faib hluav taws xob. Kev tiv thaiv hluav taws xob sib txuas ua ke muaj cov yam ntxwv hauv qab no: Nws tau siv dav. Tsis tsuas yog nws tuaj yeem siv tau raws li ib txwm muaj, tab sis nws kuj tsim nyog rau cov chaw uas thaj chaw tiv thaiv tsis yooj yim kom paub qhov txawv. Ib nrab siab thiab cuam tshuam qeeb ntawm cov cuab yeej txiav tawm hauv kev hloov pauv ntau dhau los pab ua kom lub zog sib koom ua ke. Ua qeeb qhov nce ntawm kev cuam tshuam cuam tshuam kom ua tiav qhov qis qis qis, lub neej ntev thiab lub sijhawm teb sai heev.

4. Kev xaiv ntawm lwm qhov ntsuas ntawm kev tiv thaiv hluav taws xob nyob ntawm qib ntawm thaj chaw tiv thaiv xob laim uas txhua qhov khoom tiv thaiv nyob, thiab nws qhov kev ua haujlwm hluav taws xob raug rau qhov ntsuas hluav taws xob ntawm txhua qhov khoom siv tau teeb tsa hauv Circuit Court. Cov kab hluav taws xob sib tw ua hluav taws xob tseem yuav tsum tau them sai sai rau nws qhov ntsuas tam sim no.

5. Lwm yam uas cuam tshuam rau kev faib hluav taws xob hluav taws xob hluav taws xob tam sim no: kev txo qis hauv av tiv thaiv ntawm lub davhlau ya nyob twg hloov pauv yuav nce kev faib tawm tam sim no hauv cov xov hluav taws xob. Qhov nce ntawm qhov ntev ntawm cov khoom siv hluav taws xob cable yuav txo qhov kev faib tawm tam sim no hauv cov kab hluav taws xob, thiab ua kom muaj kev faib tawm tam sim no hauv ntau lub xov hlau. Qhov luv luv cable ntev thiab qis heev nruab nrab kab tsis muaj kev cuam tshuam yuav ua rau qhov tsis sib xws tam sim no thiab ua rau muaj kev cuam tshuam hom kev cuam tshuam. Kev sib txuas sib txuas ntawm cov khoom siv hluav taws xob txuas rau ntau tus neeg siv yuav txo qhov kev cuam tshuam tsis zoo thiab nce kev faib khoom tam sim no. Hauv lub xeev cov khoom siv hluav taws xob sib txuas, qhov hluav taws xob tam sim no ib ntus feem ntau ntws mus rau hauv kab hluav taws xob. Qhov no yog qhov laj thawj yog vim li cas feem ntau qhov hluav taws xob puas tsuaj tshwm sim ntawm kab hluav taws xob.
