Txhawm rau tswj ntau lub voj voog uas muaj zog heev thiab cov txheej txheem siv hluav taws xob qis tam sim no lossis lwm yam cuam tshuam (kub, lub teeb, mechanics), cov khoom siv tshwj xeeb. Lawv txawv ntawm lub zog thiab kev tsim, tab sis lawv lub ntsiab lus yog tib yam - tig los yog tawm ntawm hluav taws xob hluav taws xob thaum lub teeb liab tswj tau txais. Lub 220V relay kuj ua haujlwm los tiv thaiv lub network.
hluav taws xob relay yog dab tsi
Nyob rau hauv ib qho hluav taws xob relay, ib lub teeb liab hluav taws xob tswj lwm lub teeb liab hluav taws xob. Nyob rau hauv cov ntaub ntawv no, tsis muaj qhov chaw rau kev hloov pauv tsis tau, tab sis tsuas yog nws hloov. Cov teeb liab tuaj yeem sib txawv kiag li hauv daim ntawv, cov duab thiab lub zog, tab sis ib qho tseem ceeb - sai li sai tau raws li qhov tam sim no pib ntws hauv kev tswj xyuas Circuit Court, qhov hloov hluav taws xob tau tshwm sim, txuas lossis txiav cov khoom thauj. Thaum tus tswj tam sim no ploj mus, lub kaw lus rov qab mus rau nws qhov qub.
Electric relay - ib yamamplifier, yog hais tias, piv txwv li, ib tug tsis muaj zog teeb liab hloov ib tug muaj zog, thiab nyob rau tib lub sij hawm lawv zoo sib xws nyob rau hauv cov duab thiab hom ntawm voltage. Koj tseem tuaj yeem xav txog cov cuab yeej xws li lub converter yog tias cov teeb liab sib txawv ntawm ib leeg hauv cov duab ntawm qhov voltage.
Txoj Cai Ua Haujlwm
Koj tuaj yeem pom meej qhov kev txiav txim ntawm relay ntawm tus piv txwv ntawm ib qho hluav taws xob. Xws li ib tug mechanism muaj ib tug winding nrog ib tug hlau core thiab ib pab pawg neeg ntawm kev sib cuag uas txav mus los, kaw thiab qhib lub Circuit Court. Ib tug tswj tam sim no yog siv rau cov tub ntxhais kauj. Qhov tam sim no, raws li txoj cai ntawm electromagnetic induction, tsim ib qho chaw sib nqus hauv cov tub ntxhais, uas nyiam cov pab pawg sib cuag rau nws tus kheej, thiab nws kaw lossis qhib hluav taws xob, nyob ntawm seb hom relay.
Type of relays
Cov cuab yeej piav qhia tau muab cais raws li ob peb yam. Piv txwv li, raws li hom voltage, AC relay lossis DC relay yog qhov txawv. Raws li txoj cai, cov khoom siv no sib txawv ntawm ib leeg nkaus xwb nyob rau hauv hom ntawm cov tub ntxhais, lossis theej, nws cov khoom siv. Relays mus tas li yog tus cwj pwm los ntawm cov tub ntxhais hluav taws xob hluav taws xob, thiab lawv tuaj hauv ob hom:
- Neutral.
- Polarized.
thawj tus txawv ntawm qhov thib ob uas lawv tuaj yeem ua haujlwm nyob rau txhua qhov kev coj ntawm qhov tam sim no dhau los ntawm kev xa xov.
Yog tias peb xav txog hom kev tswj lub teeb liab thiab cov qauv tsim ntawm lub cuab yeej, tom qab ntawd muab faib ua:
- Electromagnetic, uas muaj cov hlau nplaum hluav taws xob uas hloov pauvhu rau.
- Solid State. Lub tshuab hluav taws xob hloov tau sib sau ua ke ntawm thyristors.
- Thermostat raws li ntsuas kub.
- Ntev relay 220V.
- Optical, qhov twg lub teeb liab tswj yog lub luminous flux.
voltage tswj relay
Txhawm rau tswj cov kev sib txuas hluav taws xob, lossis theej, qhov ntsuas hluav taws xob, 220V relays tau tsim. Lawv tau tsim los tiv thaiv cov khoom siv hluav taws xob hauv tsev los ntawm qhov hluav taws xob tam sim ntawd. Lub hauv paus ntawm cov khoom siv no yog qhov tshwj xeeb ceev ceev microcontroller. Nws saib xyuas cov qib voltage hauv lub network. Yog tias vim qee yam muaj qhov sib txawv ntawm qhov hluav taws xob nce lossis nqis los ntawm qhov kev tso cai txwv, ces lub teeb liab tswj tau raug xa mus rau lub cuab yeej, uas cuam tshuam lub network ntawm cov neeg siv khoom.
Lub 220V relay pib yog nyob rau hauv thaj tsam ntawm 170-250 Volts. Qhov no yog tus qauv lees paub. Thiab thaum lub network raug kaw, kev tswj ntawm qib voltage hauv nws txuas ntxiv. Thaum qhov hluav taws xob rov qab mus rau qhov kev txwv tsis pub dhau, lub sijhawm ncua sijhawm tau qhib, tom qab ntawd cov khoom siv tau rov ua dua.
Cov khoom siv zoo li no feem ntau yog nruab rau ntawm lub tswv yim ntawm lub voj voog tom qab lub ntsuas hluav taws xob thiab lub ntsuas hluav taws xob. Lub hwj chim ntawm cov cuab yeej yuav tsum nrog cov npoo kom tiv taus qhov hluav taws xob nce siab thaum lub voj voog thauj khoom tawg.
ncua sijhawm relay 220V
Cov cuab yeej, lub ntsiab lus uas yog los tsim cov xwm txheej uas cov khoom siv ntawm cov hluav taws xob hluav taws xob ua haujlwm hauv ib ntus, hu ua lub sijhawm relay. RauPiv txwv li, yog tias koj xav tau los tsim ib qho kev hloov pauv hloov tsis tau tam sim ntawd thaum tuaj txog ntawm lub teeb liab tswj, tab sis tom qab lub sij hawm teem, ib qho system siv. Muaj cov khoom siv npe hauv qab no:
- Sijhawm relay 220V hluav taws xob hom. Lawv tuaj yeem muab lub sijhawm nthuav tawm hauv feem ntawm ib thib ob thiab mus txog ntau txhiab teev. Lawv tuaj yeem raug programmed. Kev siv lub zog ntawm cov khoom siv no tsis tsim nyog, thiab qhov ntev me me.
- Nrog solenoid deceleration lub sij hawm rau DC mov circuits. Lub Circuit Court yog raws li ob lub electromagnetic coils, nyob rau hauv uas sib nqus fluxes ib txhij tshwm sim, qhia nyob rau hauv lub opposite kev taw qhia thiab yog li tsis muaj zog ib leeg rau lub ncua sij hawm.
- Cov khoom siv uas lub sijhawm teb tau qeeb los ntawm cov txheej txheem pneumatic. Lub shutter ceev tuaj yeem nyob hauv 0.40-180.00 vib nas this. Qhov ncua sij hawm ntawm kev ua haujlwm ntawm pneumatic damper yog ua los ntawm kev kho cua kom tsawg.
- Devices ntawm lub thauj tog rau nkoj mechanism lossis clockwork.
nruab nrab relay 220V
Cov cuab yeej zoo li no suav tias yog lub cuab yeej pabcuam thiab siv ntau yam tsis siv neeg circuits, nrog rau kev tswj hwm. Lub hom phiaj ntawm qhov nruab nrab relay yog kev cuam tshuam kev ua haujlwm hauv kev sib cuag ntawm ib pawg neeg. Nws tseem tuaj yeem qhib ib lub voj voog thiab tua lwm qhov tib lub sijhawm.
Schemes rau kev hloov ntawm 220V nruab nrab relay yog ob hom:
- Raws li txoj cai shunt. Hauv qhov no, txhua yam uas pubvoltage yog siv rau relay coil.
- Los ntawm serial type. Ntawm no cov winding ntawm lub tshuab nrog lub kauj hloov yog txuas nrog hauv series.
Nyob rau hauv lub relay Circuit Court, nyob ntawm seb nws tsim, tej zaum yuav muaj txog peb windings ntawm lub coils.
