Lam ua relay rau teeb pom kev zoo tswj: qhov kev piav qhia thiab ntsiab cai ntawm lub lag luam

Hloov - ib tug ntaus ntawv rau switching ib tug hluav taws xob Circuit Court nrog variation ntawm lub tswv yim. Classical variant yog ib qho electromechanical ntaus ntawv uas yuav qhib los yog kaw neeg thaum dhau los ntawm lub winding ntawm ib tug hluav taws xob tam sim no. Lam ua relays los tswj teeb kuj muaj ob lub xeev: rau hauv thiab tawm. Tab sis lawv pom qhov txawv feature yog tus tes hloov qhov lub xeev nrog ib tug ib mem tes. Tom qab koj nias tus tes hloov qhov khawm uas ua hauj lwm nyob rau hauv lub hauv paus ntsiab lus ntawm ib tug hluav taws xob tswb nyees khawm, los yog los ntawm ib tug kauj tswj Circuit Court kis luv luv voltage mem tes uas ua hauj lwm pab hloov lub ntsiab hu. Yog hais tias ib tug pa relay tom qab lub voltage tseem nyob rau ntawm mem tes (bistable) nws yog muab tshem tawm. Tab sis nyob rau tib lub sij hawm switching hu, switching lub load, nws yog tseem yuav mus nyob rau.

Qhov zoo ntawm cov impulse relays

1. Zog yog tsis noj kom muaj lub "on". Zog yog siv tsuas yog nyob rau tus tes hloov qhov.
2. Nyob ntsiag to lub lag luam.
3. Muaj peev xwm mus cuag yam tsawg taug kev-los ntawm keyboards.
4. Thaiv nyiaj, txij li thaum nws yuav tsum tau ib tug me me ntoo khaub lig seem rau ua hauj lwm tswj. Nyob rau hauv tas li ntawd, txhua sib txuas lus hloov tsuas yog ob tug nyob ntawm tej.
5. Ntau yam kev siv nyob rau hauv lub tsev thiab nyob rau hauv hluav taws xob circuits.

hom ntawm Relay

Cov hluav taws xob no yog ua los ntawm ob peb yam:

1. Electromagnetic. Yog tswj los ntawm ib tug electromagnet switching hu. Thaum dua ib tug hluav taws xob mem tes los ntawm nws cov winding tshwm sim triggering lub switching mechanism tsim los ntawm qhov kev txiav txim ntawm lub magnetic teb.
2. Hauv. Nws nyob rau ntawm lub network. Thaum lub ua manufacturers ntawm zoo mus kom ze rau EMI.

Daim ntawv thov ntawm impulse relays

Lub peev xwm ntawm lub teeb ntaub ntawv rau tus switching tswj keyboards ntaiv. Ua-nyob rau hauv timer tso cai rau koj mus tua lub teeb nyob rau hauv lub theem ntaiv ntawm lub tsev tom qab ib tug set lub sij hawm ntawm lub sij hawm. Mem tes relay yog ntsia tau rau hauv lub teeb, nyob rau hauv lub hlws ris lub thawv los yog tswj vaj huam sib luag. Tsis tas li ntawd, nws yuav tau ib feem ntawm ib tug ntaiv 403 BIS-hom tshuab.

Raws li bistable relays yog siv rau cov switching rau hauv thiab tawm teeb pom kev zoo nyob rau hauv ntau qhov chaw, muab ib tug yooj yim to taub daim duab ntawm qhov hluav taws xob thaiv nyob rau hauv kev sib piv nrog zaj keyboards.

Txuas impulse relay rau teeb pom kev zoo tswj

Tus ntaus ntawv muaj 4 zis:

• pub theem;
• nruab nrab neeg xyuas pib;
• nkag tau mus rau cov nyees khawm;
• theem tso zis rau lub teeb.

Nruab nrab yog kev cob cog rua rau lub teeb qhov chaw nyias.

Siv cov kev twb kev txuas yog los ua kom lub sij hawm ntawm lub teeb. Lawv tus xov tooj yuav tsis muaj ntau tshaj li 10, txwv tsis pub muaj yuav tsis muaj tseeb positives. Feem ntau lawv nqi yog tsis ntau tshaj li 2.4. Koj muaj peev xwm teem ntau tshaj li 10, yog hais tias tus tswj thaiv yog nyob nyias los ntawm lub hwj chim thiab txuas ntxiv capacitor.

Cov kev siv thiab kev siv

Lam ua relay rau teeb pom kev zoo tswj yog ib qho yooj yim mus use. Txawm tias muaj cov electronics, tus ntaus ntawv yog txaus txhim khu kev qha siv. Nws muaj ib tug sensor chav tsev thiab ib tug hluav taws xob kauj. Yog powered los ntawm cov mains. Lub Circuit Court muaj ib tug tswj Circuit Court thiab load. Tus ntaus ntawv ua hauj lwm ntsiag to thiab nco rau yav dhau los tej chaw.

RIO 1 Pulse relay

Pulse teeb pom kev zoo tswj relay RIO-1 muaj cov nram qab no muaj mob:

• Y - qho switching rau hauv thiab tawm lub hwj chim Circuit Court los ntawm pheej nias;
• Y1 - hloov;
• Y2 - tawm;
• N - nil;
• 11-14 - feem ntau qhib hu.

Muaj kev cob cog rua rau 2 Button On / Off hloov rau lub teeb ntawm lub chaw sib txawv, tab sis koj muaj peev xwm tseem nruab siv lawv nyob rau hauv thaum uas tig mus. teeb pom kev zoo Circuit Court nyob rau 10 A Circuit Court breaker yog ntsia mus rau tiv thaiv lawv. Fais fab hu RIO-1 relays mas tam sim no 16 A. Yog hais tias koj xav tau ntau lub hwj chim, teeb pom kev zoo tswj ntawm impulse relay yog tsim los ntawm lub contactor.

Yog hais tias lub teeb yog tawm, nias tej khawm hloov lub teeb liab yog noj mus rau lub tswv yim Y. Yog li muaj ib tug Circuit Court ntawm lub hwj chim hu 11-14, uas ceev lub teeb.

Nias tus yuam sij hloov ntawm tej theem dua txhab khoom mus rau lub tswv yim Y, tab sis twb muaj ib tug disconnection ntawm lub hwj chim hu 11-14, lub switching-off teeb pom kev zoo. Tsav yog considerably yooj yim dua thaum uas siv cov taug kev-los ntawm keyboards thiab tsis muaj ntau nyuab thaum tshiab thaum uas tig mus kev twb kev txuas.

Yuav kom pab txhawb troubleshooting thaum lub sij hawm ib tug luv luv Circuit Court nws yog advisable rau nruab ib daim Circuit Court breaker rau lub hwj chim tswj Circuit Court 6 A. Ces, ib zaug nws yuav luaj li cas lub kev twb kev txuas yog faulty, rau nws txhais tiv thaiv. Yog li nyob rau hauv cov kev tswj Circuit Court yuav tsum me hlau seem (0.75 hli ^2).

Mem tes relay Abb

Yog hais tias koj xav kom koj muab tus mem tes relay los tswj teeb pom kev zoo, Abb haum txoj kev xwb.

Nws zoo yog raws li nram no:

1. Lub xub ntiag ntawm ntxiv terminals rau centralized tswj. Los ntawm lawv, koj yuav yuam tus tes hloov qhov los yog tua teeb pom kev zoo, seb nws yog nyob rau hauv dab tsi mob. Ces nws yog ua tau los ntawm lawv mus cuag tag nrho cov keyboards thiab tswj lawv nyob rau hauv cooling, piv txwv li, tig tawm tag nrho cov teeb thaum tawm hauv lub tsev.
2. Group E250 GM tsev rau xaiv tig tawm lub teeb pom kev zoo nyob rau hauv lub plag tsev los yog cia li nyob ib ncig ntawm lub tsev.
3. Kuj mus cuam electromechanical Abb.
4. Kuaj tswj relay hu manually siv cov qib ntawm tus dais. Qhov no yog pab tau thaum cov khoom no poob qab xwb.
5. Muaj peev xwm mus ua hauj lwm rau tib neeg thiab alternating tam sim no tsim loj zoo rau txawv daim ntaub ntawv.

Lam ua relays los tswj teeb pom kev zoo Abb kuj muaj disadvantages:

• muaj peev xwm rau nruab tsuas phaj nyob rau DIN-rail;
• tus nqi siab.

Txawm tias tus nqi, ntau tau lam ua Relays Abb nyob rau hauv kev twb kev txuas nrog lub siab cia siab rau thiab kev tiv thaiv rau cuam.

Thaiv cov hlab hloov Legrand

Analogs Abb cov khoom uas impulse relay rau teeb pom kev zoo tswj Legrand. Lawv zoo yog cov nram qab no:

• ntau yam uas pab tau kev khiav dej num uas yuav tsum tau hloov siv ntxiv accessories (taw hu, ib qho ntxiv tswj ntaus ntawv compensator li al.);
• efficiency thiab kev cia siab;
• tsis sib txuas;
• ywj siab kev twb kev txuas ntawm lub hwj chim thiab kev tswj Circuit Court ntawm cais terminals.

Legrand qauv kuj muaj nqi, tab sis lawv yog cov heev justified thaum siv kom yog yog.

xaus

Lam ua relays los tswj teeb pom kev zoo yuav tsim ntxiv kev nplij siab nyob rau hauv ib tug tsev los yog lub tsev. Thaum siv kom zoo, lawv yog yig thiab txhim khu kev qha. Nyob rau hauv tas li ntawd, cov qauv ntawm cov kev manufacturers coj tshiab nta cov kev tswj ntawm lub teeb, tsis muaj uas nws yog tsis txaus.
