History

thawj lub tshuab ABB tau tshwm sim thaum kawg ntawm lub xyoo pua 18th. Thaum qee qhov xwm txheej tshwm sim, piv txwv li, nyob rau hauv qhov kev tshwm sim ntawm lub luv luv Circuit Court, lawv txiav tawm lub hwj chim mov ntawm lub network, uas yog raws li nyob rau hauv incandescent qhov muag teev. Tab sis qhov tshwj xeeb no tsis muaj nyob rau hauv cov khoom lag luam, thiab cov khoom siv zoo li cov qauv niaj hnub no tau nthuav dav ntau tom qab.

Lub tshuab yog Ameslikas raws li tus qauv tsim ntawm cov hlau nplaum-thermal splitter. Tab sis vim qhov no, ABB cov cav tov sai sai tau siv tsis tau, thiab lawv txoj haujlwm tau txawv ntawm qhov muaj kev cuam tshuam. Tsis tas li ntawd, ib qho arc feem ntau tau tsim, yog li yuav tsum muaj kev qhia txog kev siv tshuab tshiab.

Ntse

Kev ua haujlwm hluav taws xob tsis yooj yim, txoj haujlwm tseem ceeb yog ua raws txhua txoj cai thiab ua kom muaj kev nyab xeeb. Lub Circuit Court breaker tiv thaiv qhov tshwm sim ntawm hluav taws kub txaus ntshai los ntawm tripping thaum lub network yog overloaded los yog luv luv circuited. Muaj ntau hom khoom siv no, uas tau muab faib ua ob pawg dav - cov no yog cov khoom siv AC thiab DC. Nws yog ib qho tsim nyog nkag siab txog thawj qhov kev xaiv hauv kev nthuav dav ntxiv, txij li ABB DC-based tshuab yog qhov tsawg kawg nkaus hauv lub neej niaj hnub. Cov cuab yeej tau muab faib ua raws li cov txheej txheem tseem ceeb, suav nrog kev ua haujlwm tam sim no, ntsuas qhov ntsuas hluav taws xob thiab tus lej ntawm tus ncej, tag nrho cov uas tau cim rau hauv cov cim thiab cov lus qhia ua ke.

Rated voltage thiab ua haujlwm tam sim no

Lub zog ntawm cov khoom siv txuas nrog lub network ncaj qha nyob ntawm qhov ua haujlwm siab tshaj plaws tam sim no. Ntawd yog, thaum txhim kho lub cuab yeej nrog qhov ntsuas tsis txaus ntawm qhov siab, nws yuav tsuas yog khob tawm. Nyob rau tib lub sijhawm, daim thaiv hluav taws xob rau kev muab nrog lub zog tshaj qhov tsim nyog tsis yog ib txoj hauv kev tawm ntawm qhov xwm txheej, vim nws yuav tsis teb rau qhov luv luv. Ntawm no, yuav tsum tau ua raws nraim ntawm txhua qhov ntsuas.

Thaum xaiv qhov ntsuas qhov ntsuas hluav taws xob, tsis tas yuav tsum ua cov lej, txij li cov khoom siv nrog tus nqi ntawm 220 V yog qhov tsim nyog rau lub voj voog uas muaj qhov sib xws, tib yam siv rau cov khoom siv nrog qhov hluav taws xob ntawm 12 V. Nyob ntawm hom, keyboards tuaj yeem muaj los ntawm ib mus rau pebncej.

Cov kev xaiv nrov heev yog cov hluav taws xob sib txawv tam sim no tiv thaiv hluav taws xob hluav taws xob. Lawv muaj kev tiv thaiv txaus, suav nrog kev muaj peev xwm tiv thaiv tam sim no los ntawm cov hlau hlau.

Kev txuas lub cuab yeej yog nyob rau hauv lub zog ntawm leej twg, thiab tsis muaj kev paub tshwj xeeb thiab kev paub hauv kev ua haujlwm hluav taws xob xav tau. Qee qhov xwm txheej, nws tuaj yeem nyuaj rau kev sib txuas ruaj khov thiab txav cov neeg sib cuag, txawm tias tsis muaj cov cai tsim los ntawm lub sijhawm no. Kev xaiv kev sib txuas tsis cuam tshuam rau kev ua haujlwm ntawm lub cuab yeej vim yog tripping tom qab luv luv Circuit Court lossis overload.

Kev xaiv

Thaum npaj cov khoom siv hluav taws xob hauv ib chav tsev lossis lub tsev, txoj haujlwm ntawm kev xaiv txoj cai hloov feem ntau tshwm sim. Txij li thaum lub neej ua haujlwm ntev ntawm cov khoom siv hauv tsev thiab kev tiv thaiv ntawm cov xaim hluav taws xob los ntawm qhov muaj peev xwm ntawm hluav taws yog nyob ntawm qhov kev xaiv muaj peev xwm, nws yog ib qho tsim nyog yuav tau kho nws nrog kev saib xyuas zoo tshaj plaws. Ua ntej ntawm tag nrho cov, lub load ntawm cov kab thiab nominal yam ntxwv ntawm lub cable mus rau lub qhov hluav taws xob yuav tsum tau coj mus rau hauv tus account. Feem ntau siv hluav taws xob Circuit Court breakers ntawm electromagnetic los yog thermal hom. Lub tom kawg yog raws li cov cua kub ntawm lub bimetallic phaj thaum ib tug hloov los ntawm lub teeb theem ntawm cov ntsuas tam sim no, thaum lub sij hawm mus txawv tebchaws qib yog tsiv los ntawm lub expansion phaj. Overcurrents uas tshwm sim thaum lub caij luv luv raug ntes los ntawm kev tiv thaiv electromagnetic thiab de-energize lub network.

ThaumXav tau kev pab kws tshaj lij?

Ib qho hluav taws xob hluav taws xob, tus nqi pib ntawm 1500 rubles, zoo li lwm cov txheej txheem, tsis tuaj yeem nyob mus ib txhis, nws thiaj li tawg, hnav tawm, uas ua rau nws tsim nyog los hloov nws. Ua ntej tshaj plaws, ua ntej pib ua haujlwm, koj yuav tsum tau txiav cov kab txuas nrog lub cuab yeej, tom qab ntawd nws tuaj yeem muab tshem tawm. Tuav lub tshuab pib lossis lub hnab yuav tsum tau hloov pauv hloov.

Nws tsim nyog sau cia tias qee qhov kev ua, piv txwv li, hloov lub hnab, yuav tsum tau ua los ntawm cov kws tshaj lij, vim tias feem ntau nws tsis tuaj yeem txo qhov voltage ntawm lub switchgear yam tsis muaj kev pab sab nraud.

Yuav tsum siv lub tshuab ntsuas ntau los ntsuas qhov hluav taws xob tom qab txiav tawm, qhov no yuav ua kom nws tsis tuaj. Tom ntej no, tus neeg xyuas pib raug tshem tawm thiab lub tshuab hluav taws xob raug tshem tawm, tus nqi ntawm qhov nyob ntawm nws hom. Qee lub sij hawm nws tsis tuaj yeem unscrew lub clamps nrog lub hau ntswj, nyob rau hauv rooj plaub no koj yuav tsum tau tom cov xov hlau nrog kev pab los ntawm sab cutters. Qhov teeb meem no tsis tshwm sim nyob rau hauv niaj hnub versions, uas muaj tshwj xeeb latches nyob rau hauv qis grips. Ua tsaug rau lawv, tsis tas yuav siv cov cuab yeej tshwj xeeb los ua haujlwm.

Koj yuav tsum paub dab tsi?

Ua ntej kev teeb tsa hauv lub tshuab hluav taws xob, nws yog ib qho tsim nyog yuav tsum tau ua lub chaw kuaj xyuas ntawm lub Circuit Court breaker. Raws li qhov tseeb tias kev ywj pheej ua cov haujlwm no hauv tsev tuaj yeem ua rau muaj teeb meem, ib tus tsis tuaj yeem ua yam tsis muaj kev qhia ntawm tus kws tshaj lij. Rau nruab, cov kauj ruam yog thim rov qab rau covuas tau nqa tawm kom tshem tawm nws: mounting lub cuab yeej ntawm ib lub tsheb ciav hlau, kho thiab kho cov xaim hauv cov clamps. Tom ntej no, tam sim no yog muab rau lub vaj huam sib luag hluav taws xob (xws li muab, piv txwv), kev teeb tsa tuaj yeem txiav txim siab ua tiav yog tias tsis muaj lub teeb lossis lub suab hloov pauv, tshwj xeeb yog tawg lossis tawg.

Kev sib txuas

Kev sib txuas zoo ntawm lub cuab yeej tsis muaj qhov tseem ceeb dua li nws qhov kev teeb tsa. Nyob rau hauv cov ntaub ntawv no, koj yuav tsum tau txiav txim siab rau txoj kev, piv txwv li, nyob ruaj los yog tsiv hu. Raws li cov kws tshaj lij, thawj qhov kev xaiv yog qhov tseem ceeb, vim nws muaj kev nyab xeeb dua rau kev ua haujlwm txuas ntxiv ntawm hluav taws xob.

Raws li txoj cai, rau 220 V ib-theem hom, ob-ncej thiab ib-ncej el. automata. Nyob rau hauv cov ntaub ntawv no, lub ntsiab lus ntawm lub installation variant tsis ua teeb meem. Cov khoom siv nrog ob tus ncej yog siv los tua xoom thiab theem tib lub sijhawm, lawv kuj muaj plaub qhov kev sib cuag. Cov tswv yim xoom yog haum rau lub davhlau ya nyob twg thib peb, thiab cov khoom siv theem txuas nrog rau thawj. Raws li, lwm lub davhlau ya nyob twg raug faib.

ABB's peb-ncej Circuit Court breakers yog siv thaum muaj peb theem input, txawm tias qhov no, lawv cov kev teeb tsa yooj yim heev thiab xav kom txhua theem txuas nrog rau sab saum toj clamps ntawm lub hnab.

Yuav ua li cas yog ntau yam?

Modular circuit breakers muaj nyob rau hauv ntau yam versions, feem ntau ntawm lawv yog tsim los rau Circuit Court breaker thiab tsuas muaj ib tug muaj nuj nqi - tiv thaiv lub network los ntawm overheating.loads. Muaj kev faib raws li lub zog ntawm cov kis tam sim no. Txhawm rau kom muaj kev ua haujlwm thaum muaj xwm txheej ceev, lub cuab yeej muaj qee qhov chaw rau ntau qhov kev nkag siab zoo. Lawv yog tsim nyob rau hauv lub Hoobkas, raws li, cov khoom muag muag nrog ib tug cim nyob rau hauv daim ntawv ntawm ib tug xov tooj pib pib.

Tib lub sijhawm, kev suav ntawm qhov xav tau yuav tsum tau ua ob qho tib si los ntawm tag nrho cov neeg siv khoom siv hluav taws xob, thiab los ntawm cov khoom siv hluav taws xob muaj, thiab cov xaim.

ABB Circuit Court breakers, tus nqi ntawm RUB 1,500 thiab RUB 5,000, muab faib ua peb pawg lus teb: ceev, qauv, thiab xaiv.

Cov ntaub ntawv ntawm txhua yam khoom siv yog ua los ntawm cov yas ruaj khov, muaj lub mount rau sab nraub qaum, uas ua kom yooj yim installation. Rau kev rhuav tshem, ntau tus qauv tau nruab nrog lub qhov muag tshwj xeeb rau saum toj, uas nws txaus los rub me ntsis.
