Hauv hluav taws xob, tag nrho cov txheej txheem ntawm kev kaw thiab qhib lub network feem ntau hu ua kev hloov. Cov haujlwm no yog ua los ntawm cov cuab yeej tshwj xeeb. Nws tau nruab rau hauv ntau lub voj voog thiab ua kom lub cev ua haujlwm zoo. Cov khoom siv hloov pauv yog cov khoom siv uas tsim los muab lossis tso tseg cov dej ntws ntawm hluav taws xob mus rau lub network.
Hnub no, ntau yam ntawm cov khoom siv tau nthuav tawm. Lawv txawv ntawm kev tsim thiab tshwj xeeb ntawm kev ua. Txhawm rau xaiv chav tsev tsim nyog, koj yuav tsum xav txog cov hom uas twb muaj lawm thiab lawv cov yam ntxwv.
yam ntxwv dav dav
Lub hom phiaj ntawm kev hloov khoom siv tau txo qis rau cov txheej txheem ntawm kev xa hluav taws xob vim yog kaw thiab qhib qhov hluav taws xob. Niaj hnub no, tag nrho cov khoom uas twb muaj lawm ntawm hom no tuaj yeem muab faib ua ob pawg. Thawj pawg suav nrog kev sib cuag (mechanical) cov cuab yeej, thiab pab pawg thib ob suav nrog cov khoom tsis sib cuag (semiconductor lossis gas-discharge) ntau yam.
Cov khoom siv hloov pauv ntau tshaj plaws yog cov keyboards, Circuit Court breakers, contactors,relays, fuses. Lawv muaj qee yam nta uas yuav tsum tau txiav txim siab thaum xaiv. Yuav cov cuab yeej hloov pauv raws li kev ua haujlwm.
Cov chav qhia nthuav tawm tuaj yeem muaj ntau tus ncej hauv lawv qhov tsim. Lawv tus lej tuaj yeem yog los ntawm ib mus rau plaub. Raws li qhov ntsuas no, cov khoom siv kuj tau muab faib ua pawg. Feem ntau, cov khoom muag bipolar yog muag. Lawv muaj ob txoj haujlwm - "tawm" lossis "rau".
riam hloov
Cov khoom siv hloov pauv tuaj yeem tswj tau manually lossis los ntawm cov lus teb tsis tiv tauj rau kev hloov pauv hauv ib puag ncig. Qhov yooj yim sib txawv ntawm cov cuab yeej cuab tam yog riam hloov. Nws yog tswj manually.
Cov cuab yeej siv rau kev hloov hauv cov hluav taws xob hluav taws xob uas muaj qhov hluav taws xob tsis tshaj 660V. Ntawm kev muag khoom yog ib-, ob- thiab peb-ncej ntau yam ntawm units. Nrog kev pab los ntawm ib rab riam hloov, lub Circuit Court yog disconnected nyob rau hauv voltage los yog tsis muaj nws. Lub chaw tsim khoom muaj npe nrov hauv peb lub tebchaws ntawm cov khoom siv nthuav tawm yog Kursk cov cuab yeej hluav taws xob cog.
Riam hloov tuaj yeem ua haujlwm hauv tsev lossis kev lag luam. Thawj qeb yog tsim los siv nyob rau hauv ib tug tsawg-voltage network, thiab lub thib ob - nyob rau hauv ib tug high-voltage network. Qhov no yog cov cuab yeej nrhiav tom qab uas siv yuav luag txhua qhov chaw.
Ntau yam riam hloov
Cov khoom siv hloov pauv, uas yog cov khoom siv hluav taws xob, tig mus, muab faib ua pawg. Muab faibdisconnector, hloov thiab luv luv Circuit Court. Hauv thawj kis, lub cuab yeej cuam tshuam cov khoom siv hluav taws xob rau lub voj voog, uas muaj lub zog me me tam sim no. Hom ntsuas no yog siv los tshuaj xyuas lossis kho qhov system. Lub disconnector muaj qhov sib txuas rau kev sib cais.
Hloov hloov hluav taws xob tam sim no ntawm ib lub voj voog mus rau lwm qhov. Lub luv luv circuiter tsis tsim thiab tsis siv rau hauv cov khoom siv niaj hnub no. Nws tsim qhov luv luv.
Ntawm kev muag khoom yog cov khoom siv uas sib txuas cov haujlwm uas tau nthuav tawm. Piv txwv li, nws tuaj yeem yog qhov hloov pauv disconnector. Qhov no yog riam hloov nrog lub chamber rau extinguishing lub arc. Nws tuaj yeem ua haujlwm hauv ib qho thiab ob qho kev qhia. Yog tias tsis muaj lub chamber rau kev tua cov arc nyob rau hauv xws li ib tug hloov, cov cuab yeej no belongs rau pab pawg neeg ntawm disconnectors.
Switch
Lub hom phiaj dav dav Circuit Court breaker yog lub tshuab hloov mus txog 1000 V (alternating tam sim no) thiab mus txog 440 V (ncaj tam tam sim no). Chav tsev no belongs rau cov cuab yeej siv tshuab. Nws tuaj yeem qhib, hla lossis tua cov khoom siv hluav taws xob tam sim no. Nws pab tiv thaiv hluav taws xob tes hauj lwm los ntawm overloads, tseem ceeb voltage poob los yog luv luv circuits. Qhov classic hauv qhov no yog RCD Circuit Court (suab hauv qab no).
I - RCD.
II - Cov neeg siv hluav taws xob (ntsuas ntsuas).
Lub Circuit Court breaker tuaj yeem tswj tau lub network. Ua li no, lawv tsim muab rau muaj ntau yamtsav.
Muaj ntau qhov kev hloov kho sib txawv ntawm cov khoom siv nthuav tawm. Qhov no tso cai rau lawv siv nyob rau hauv yuav luag txhua qhov chaw ntawm lub zog. Feem ntau, pob hom keyboards yog siv nyob rau hauv domestic thiab industrial networks.
hom kev hloov pauv tseem ceeb
Cov khoom siv hloov pauv tau nthuav tawm muaj ntau txoj hauv kev. Tsis siv neeg ntau yam suav nrog cov khoom siv tam sim no seem thiab cov hloov pauv sib txawv. Hauv thawj kis, RCD Circuit Court muaj peev xwm tiv thaiv ib tus neeg los ntawm hluav taws xob poob thaum muaj xwm txheej ceev. Differential switches yog ib hom kev hloov tshwj xeeb. Hauv nws tus qauv tsim, RCD txuas nrog rau qhov hloov. Qhov no muab kev tiv thaiv zoo tiv thaiv hluav taws xob.
Pob ntawv hloov pauv yog siv rau cov khoom siv hluav taws xob uas muaj qhov hluav taws xob ntawm 110-380 V. Lawv tau teeb tsa txhawm rau tswj cov asynchronous motors, ua tiav cov khoom siv. Xws li cov khoom siv hloov pauv tau sib sau ua ke ntawm qhov chaw ntawm lub ntsej muag square. Nyob rau hauv cov ntaub ntawv no, lub system muaj xws li ib tug tej yam xov tooj ntawm xws units. Nws muaj ib tug kov thiab ib tug mechanism rau nws fixation. Thaum nws tig, lub ncej yog teem nyob rau hauv motion. Lub koob yees duab hloov ntawm lub cuab yeej qhib lub voj voog.
Lub hom phiaj dav dav ntawm cov hluav taws xob hluav taws xob hloov pauv mus txog 1000 V. Lawv tuaj yeem ua haujlwm ob qho tib si nrog kev hloov pauv thiab ncaj qha tam sim no. Lawv suav nrog tsav, tso tawm.
Tsav thiab tso tawm
Tus tsav ntawm lub tshuab hloov pauv yog tsav manually lossiscontactless txoj kev. Muaj cov txheej txheem nrog kev tswj hwm kev sib koom ua ke. Hloov tawm yog ua los ntawm cov springs. Lawv tau teem rau hauv tsab ntawv tsa suab tom qab kev tso tawm raug txiav tawm. Qhov no tshem tawm qhov muaj peev xwm tuav cov neeg nyob hauv txoj haujlwm thaum muaj xwm txheej ceev.
Qhov kev tso tawm yog qhov system ntawm ligamentous articulated levers. Lawv txuas lub actuator mus rau cov neeg tsiv teb tsaws chaw, uas nyob rau hauv lem yog nyob ib sab ntawm lub caij nplooj ntoos hlav qhib.
Nws yog qhov kev tshaj tawm uas yog lub luag haujlwm rau kev tswj xyuas qhov yuav tsum tau ua ntawm Circuit Court lawv tiv thaiv. Yog hais tias lub kaw lus muaj kev sib txawv ntawm tus nqi ib txwm, cov ntsiab lus no kaw lub hwj chim.
Auto trip method
Cov khoom siv tiv thaiv kev hloov pauv muaj cov relays hauv lawv tus qauv tsim. Lawv yog ib feem ntawm cov breakers. Relays tuaj yeem yog electromechanical lossis static. Tsim kev tswj thiab sib piv ntawm cov txheej txheem teev tseg ntawm cov khoom siv semiconductor. Lub hauv paus ntsiab lus no tau muab tso rau hauv cov tshuab ua ntej.
Electromechanical ntau yam tuaj yeem ua los ntawm electrothermal, electromagnetic los yog cov khoom sib xyaw ua ke. Lub tswv yim hloov khoom siv ntawm hom nthuav tawm yog ntsia hauv cov tsev, tsev, chaw tsim khoom, thiab lwm yam.
Tso tawm yuav tsis muaj lub sijhawm teem caij thaum mus ncig. Tsis tas li ntawm kev muag khoom yog cov khoom siv nrog kev ywj pheej los yog kev ua haujlwm nrog kev hloov pauv tam sim no.
Lwm yam ntau yam
Kev hloov pauvLub apparatus kuj muaj xws li fuses, contactors thiab relays. Hauv thawj kis, kev cuam tshuam yog ua los ntawm kev rhuav tshem cov ntsiab lus tshwj xeeb. Lawv ua hluav taws xob.
Cov neeg sib cuag yog siv rau lub hwj chim qhib, lub zog tawm haujlwm. Cov pab pawg no suav nrog cov pib, pib thiab ballast-type rheostats. Cov hluav taws xob relay tej zaum yuav yog ib qho khoom siv cais. Nws ua hauj lwm qhib lub network nrog cov tsis muab.
Tau txiav txim siab cov cuab yeej hloov pauv siv hauv cov khoom siv hluav taws xob niaj hnub no, koj tuaj yeem txiav txim siab zoo thaum xaiv cov khoom siv.
