Ib tug relay yog ib electromagnetic hloov ua los ntawm cov hluav taws xob me me uas tuaj yeem qhib lossis tawm hluav taws xob loj dua. Lub plawv ntawm ib tug relay yog ib electromagnet (ib lub kauj ntawm cov hlau uas dhau los ua cov hlau nplaum ib ntus thaum hluav taws xob ntws los ntawm nws).
Dhau li ntawm no, dab tsi yog qhov sib nqus hloov siv rau?
Yooj yim sib nqus keyboards yog siv rau txheeb xyuas qhov qhib qhov rooj thiab qhov rais. Ib qho yooj yim magnetic hloov muaj ob ntu - lub hlau nplaum thiab magnetic rhiab heev hloov (feem ntau yog ib tug reed hloov nyob rau hauv ib lub hnab ntawv iav). Hloov tej zaum yuav yog ib txwm qhib (kaw ntawm lub tswb) lossis ib txwm kaw (qhib ntawm lub tswb).
Qhov thib ob, 12 volt relay ua haujlwm li cas? Feem ntau 12 volt relays ua haujlwm cov khoom siv hauv tsheb thiab lwm yam tsav tsheb. Thaum koj siv me me tam sim no rau lub relay coil, qhov no kaw kev sib cuag uas nyob rau hauv lem pub zog rau ib tug accessory uas ib txwm xav tau ntau tam sim no rau ua haujlwm.
Kuj paub, qhov hloov magnetic ua haujlwm li cas?
Thawj tsim nyob rau hauv 1930s, magnetic keyboards ua haujlwm zoo ib yam li relays, kaw ib qho hluav taws xob tiv tauj nyob rau hauv lub xub ntiag ntawm a Sib nqus teb. Tsis zoo li relays, sib nqus keyboards raug kaw hauv iav. Vim lawv raug kaw, sib nqus keyboards tshem tawm cov teeb meem tshwm sim hauv qhov chaw uas muaj hluav taws kub los yog tawg.
Qhov twg siv electromechanical relays?
Electromechanical relays yog keyboards uas feem ntau yog siv tswj cov khoom siv hluav taws xob muaj zog. Electromechanical relays yog siv nyob rau hauv ntau lub tshuab hluav taws xob niaj hnub no thaum nws tseem ceeb heev rau kev tswj ib lub voj voog, txawm tias muaj lub teeb liab hluav taws xob tsawg lossis thaum ntau lub voj voog yuav tsum tau tswj los ntawm ib lub teeb liab.

Dab tsi ua rau lub qhov hluav taws xob muaj hluav taws xob tsawg?
Ib qho laj thawj uas lub qhov hluav taws xob yuav muaj lowvoltageis uas nws hnav tawm. Cov hluav taws xob hluav taws xob tuaj yeem hnav tawm tib yam li txhua yam khoom siv lossis cov khoom siv hluav taws xob.Qhov txuas tsis tu ncua thiab tshem tawm cov hlua rau hauv lub qhov hluav taws xob tuaj yeem loosen thiab hnav cov kev sib txuas
Chav hluav taws xob hloov hluav taws xob yog dab tsi?
Chav hloov. ib cheeb tsam uas muaj kev sib dhos ntawm cov khoom siv hluav taws xob rau kev tswj thiab kev tiv thaiv hluav taws xob circuits. chav hloov pauv tuaj yeem cuam tshuam rau lub substation tab sis tsuas muaj cov keyboards xwb. lub ntsiab hloov mus rau cais tawm hluav taws xob yog nyob rau hauv lub ntsiab switchroom
Yuav ua li cas koj xaim lub tshuab hluav taws xob mus rau qhov ntsuas hluav taws xob?
Muaj peb cov xov hlau uas yuav tsum tau txuas mus rau qhov tseeb regulator davhlau ya nyob twg. Weld lub regulator mount rau lub tsheb laij teb ncej. Txuas lub regulator rau lub mount. Txuas lub roj teeb zoo cable hlau - feem ntau yog liab - rau tus tswj. Polarize lub generator los yog alternator los ntawm tus regulator
Yuav ua li cas kom tshem tau ib tug daig prong plug los ntawm ib tug hluav taws xob qhov hluav taws xob?
Tua lub Circuit Court breaker rau lub qhov hluav taws xob. Kuaj nws nrog lub ntsuas ntsuas hluav taws xob kom paub tseeb tias lub hwj chim tawm. Tshawb xyuas lub qhov tawg kom pom tias nws tob npaum li cas hauv lub ntsaws. Yog tias nws tawm txaus, rub nws nrog ob lub koob lub qhov ntswg pliers thiab rub tawm ncaj qha
Puas yog txhua lub tshuab hluav taws xob muaj GFCI qhov hluav taws xob?
Duplex (ob chav) qhov hluav taws xob muaj nyob rau ntawm lub tshuab hluav taws xob nqa tau thiab txhua qhov khoom siv 120 volts. Hauv av txhaum kev tiv thaiv qhov hluav taws xob (GFCI) yog qhov tshwj xeeb ntawm qee cov qauv thiab tiv thaiv tus neeg siv los ntawm hluav taws xob shocks
