I. Introduction to Nqus Circuit Breakers:
Lub tshuab nqus tsev Circuit Court breakers thiab lub tshuab nqus tsev contactors tseem ceeb ua haujlwm zoo ib yam li cov hluav taws xob hluav taws xob hluav taws xob thiab cov tshuab hluav taws xob, tshwj tsis yog tias lub tshuab hluav taws xob tua hluav taws xob tau muab tso rau hauv ib puag ncig lub tshuab nqus tsev, txhim kho kev hloov mus rau ib puag ncig. Tsis tas li ntawd, vim qhov zoo ntawm lub tshuab nqus tsev rwb thaiv tsev thiab arc extinguishing kev ua tau zoo, lawv tau siv dav.
Nqus Circuit Court breaker: Nws yog ib qho khoom siv tiv thaiv uas tuaj yeem mus ncig thaum muaj kev txhaum tshwm sim hauv Circuit Court, tiv thaiv Circuit Court; nws tuaj yeem ua manually mus rau disconnect lub load tam sim no.
Contactors yog siv rau kev hloov pauv ntawm cov me me tam sim no thiab, thaum lawv muab qee qhov kev tiv thaiv (lawv feem ntau muaj kev tiv thaiv thermal overload), lawv tsis muaj lub zog khaws cia thiab cia siab rau qhov sib nqus ntawm cov kauj. Lawv tsis tuaj yeem cuam tshuam cov dej tsis raug. Raws li rau Circuit Court breakers, tsis tas yuav tsum tau piav qhia ntxiv. Nyob rau hauv cov ntaub ntawv ntawm lub peev xwm tsis tshua muaj, contactors feem ntau siv nyob rau hauv engineering daim ntaub ntawv.
Cov qauv kev khiav hauj lwm kuj txawv.
Ib qho yog rau kev hloov pauv kev ua haujlwm tam sim no, thiab lwm qhov yog rau kev cuam tshuam tsis raug tam sim no.
Lub cev hluav taws xob hluav taws xob thiab tag nrho nws cov khoom siv ua ke tuaj yeem ua tiav peb -theem tiv thaiv thiab ncua sijhawm.
II. Taw qhia rau Nqus Contactors:
1. Cov khoom siv hluav taws xob ntawm lub tshuab nqus tsev contactor muaj cov khoom siv hluav taws xob nkag thiab tawm thiab lub tshuab nqus tsev vacuum, feem ntau siv rau kev hloov pauv, thiab muaj zog tiv thaiv kev sib kis.
2. Lub tshuab nqus tsev contactors yog tsim rau AC 50Hz lub zog hluav taws xob nrog cov ntsuas hluav taws xob mus txog 1140V thiab ntsuas tam sim no txog 630A. Lawv yog siv rau kev sib txuas ncaj qha los yog kev sib txuas ntawm kev sib txuas thiab tshem tawm cov load tam sim no nyob rau hauv lub ntsiab Circuit Court, thiab yog tsim rau siv nyob rau hauv tawg- pov thawj magnetic starters muaj li ntawm ntau yam kev tiv thaiv pab kiag li lawm, tswj nquag ua peb-theem induction motors thiab lwm yam khoom siv. Lub Circuit Court breaker muaj xws li kev khiav hauj lwm mechanism, conductive circuit, sealing Cheebtsam, thiab vaj tse. Cov rwb thaiv tsev sab nraud yog ua tiav los ntawm siab -voltage bushings, thiab cov rwb thaiv tsev sab hauv yog cov rwb thaiv tsev sib xyaw. Lub conductive Circuit Court yog txuas nrog lub tshuab nqus tsev interrupter chamber ntawm conductive clips thiab tsiv thiab nyob ruaj ruaj kawg conductive daim hlau. Tag nrho cov qauv yog peb hom -ncej ntau-box hom.
3. Lub tshuab nqus tsev contactors tsim nyog rau kev tiv thaiv thiab tswj hauv substations thiab industrial thiab mining enterprise faib tshuab;
4. Qhov sib txawv ntawm lub tshuab nqus tsev contactor thiab Circuit Court breaker yog tias lub contactor yog cov khoom siv tswj, thaum lub tshuab hluav taws xob yog cov khoom siv tiv thaiv. Lub contactor tuaj yeem nquag ua haujlwm thiab muaj lub luag haujlwm ntawm kev nqa tam sim no, tab sis nws tsis muaj kev tiv thaiv ntau dhau lossis luv luv - tiv thaiv kev tiv thaiv hluav taws xob. Lub Circuit Court breaker muaj kev hloov, kev tiv thaiv overload, thiab luv luv - Circuit Court tiv thaiv kev ua haujlwm, tab sis nws qhov kev tso cai ua haujlwm tsawg dua.
5. Lub tshuab nqus tsev contactor yog ib qho khoom siv rau kev ua haujlwm dua. Nws tuaj yeem cuam tshuam cov load tam sim no tab sis tsis tuaj yeem cuam tshuam luv luv -circuit tam sim no. Nws kuj muaj ib txwm qhib thiab ib txwm kaw kev sib cuag. Nws tsis muaj luv luv - Circuit Court tiv thaiv tam sim no thiab tsuas tuaj yeem ua tiav qhib thiab kaw raws li lub teeb liab muab.

Hauv -Kev ntsuas qhov tob
1. Nqus Circuit Court Breaker
Tsim Lub Hom Phiaj: Kev Tiv Thaiv Kev Nyab Xeeb thiab Kev Tiv Thaiv
Nws lub luag haujlwm tseem ceeb yog los tiv thaiv tag nrho cov khoom siv hluav taws xob thiab cov khoom siv hauv qab. Thaum muaj teeb meem loj xws li overload los yog luv luv Circuit Court tshwm sim nyob rau hauv txoj kab, lub relay tiv thaiv ntaus ntawv xa ib lub teeb liab, thiab lub Circuit Court breaker tau sai sai (feem ntau nyob rau hauv kaum mus rau ib puas milliseconds) mus txawv tebchaws, cuam tshuam lub loj txhaum tam sim no thiab tiv thaiv qhov kev huam yuaj ntawm escalating.
Cov yam ntxwv tseem ceeb:
Kev Tiv Thaiv Kev Tiv Thaiv thiab Tshuab: Txhawm rau tiv thaiv thiab cuam tshuam cov hluav taws xob hluav taws xob thiab hluav taws xob tsim los ntawm luv luv -circuit tam sim no, nws lub tshuab nqus tsev arc extinguishing chamber, cov ntaub ntawv tiv tauj, thiab kev khiav hauj lwm mechanism yog qhov muaj zog heev.
Interlocking nrog Kev Tiv Thaiv Cov Txheej Txheem: Feem ntau nws tsis muaj peev xwm los kuaj xyuas qhov tsis raug ntawm nws tus kheej, thiab xav tau kev koom tes nrog cov khoom siv tiv thaiv sab nraud (microcomputer-raws li kev tiv thaiv kev sib koom ua ke) lossis fuses, uas kuaj pom qhov txhaum thiab teeb tsa cov lus txib tripping.
Mechanical Latching: Thaum kaw, nws cov txheej txheem kaw nws nyob rau hauv qhov chaw kaw, thiab nws yuav tsis cia li qhib txawm tias lub hwj chim tswj tau ploj mus, kom ntseeg tau tias lub zog txuas ntxiv.
Application Scenario:
Cov kab nkag thiab tawm ntawm cov nroj tsuag hluav taws xob thiab substations.
Cov chaw faib khoom tseem ceeb ntawm kev lag luam thiab kev lag luam mining thiab cov tsev siab -nce.
Kev tiv thaiv thaub qab rau cov motors loj (feem ntau yog siv hauv series nrog lub tshuab nqus tsev contactors).
2. Nqus Contactor
Lub Hom Phiaj Tsim: Kev Ua Haujlwm Nrawm thiab Tswj
Nws lub luag haujlwm tseem ceeb yog kom nquag txuas thiab txiav cov kab hluav taws xob nyob rau hauv ib txwm ua haujlwm. Piv txwv li, lub tshuab cuab yeej lub cev muaj zog yuav tsum tau pib thiab nres ntau txhiab zaus hauv ib hnub.
Cov yam ntxwv tseem ceeb:
Kev ua haujlwm siab heev: Nws cov qauv siv tshuab thiab cov tshuab electromagnetic tau ua kom zoo rau kev ua haujlwm tsis tu ncua, nrog rau lub neej txhua yam ntawm ntau lab lub voj voog.
Electromagnetic Operation and Holding: Nws ua haujlwm los ntawm kev tsim lub zog sib nqus los ntawm kev ua kom lub zog ntawm lub kauj, thiab disconnects nyob rau hauv qhov kev txiav txim ntawm lub caij nplooj ntoos hlav thaum lub hwj chim raug txiav. Lub xeev kaw yuav tsum tau muab hluav taws xob txuas ntxiv; ib zaug lub teeb liab tswj tau ploj mus (piv txwv li, nias lub khawm nres thaum muaj xwm ceev), nws yuav txiav tawm tam sim ntawd.
Tsawg luv luv-Circuit Breaking Capacity: Nws tsis tuaj yeem cuam tshuam luv luv-circuit tam sim no ntawm nws tus kheej. Nyob rau hauv kev siv tswv yim, nws yuav tsum tau siv nyob rau hauv series nrog ib tug fuse. Thaum ib qho luv luv Circuit Court tshwm sim, lub fuse tau nrawm nrawm los cuam tshuam qhov txhaum, thiab tus contactor tsuas yog lub luag haujlwm rau kev hloov pauv tsis tu ncua.
Application Scenario:
Feem ntau pib lub tshuab hluav taws xob, xws li cov cuab yeej siv tshuab, cranes, compressors, kiv cua, thiab cov twj tso dej.
Tswj hluav taws xob rauv transformers thiab capacitor them nyiaj pab kiag li lawm.
Resistive loads xav tau cov chaw taws teeb tswj tsis siv neeg.
