Qhov pib xa tawm yog ib qho khoom siv nrog teeb hluav taws xob tswj hluav taws xob thiab lub zog hluav taws xob ntawm lub nra. Cov cuab yeej no tau siv dav hauv kev tswj kav ib yam nkaus thiab hauv cov khoom siv tsis siv neeg vim nws muaj peev xwm tswj tau cov zis siab zog nrog lub zog siv hluav taws xob tsawg. Tsis tas li, cov cuab yeej no hloov lub voj voog thiab sau cov sib txawv ntawm qib qib uas xav tau.
Cov Lus Qhia

Txiav txim siab seb qhov twg yog relay koj xav tau. Ua ntej, nrhiav qhov yuav tsum tau khaws tus nqi, uas yog cov lej ntawm qhov ntsuas nkag ntawm qhov chaw uas cov xa tawm nce. Thib ob, xaiv lub hwj huam rau xa tawm. Them nyiaj tshwj xeeb rau nws lub zog yam tsawg kawg nkaus, uas yuav tsum tau muab khoom rau cov khoom ua haujlwm. Nws yog qhov tsim nyog yuav tsum tau xa cov relay los ntawm thawj lub xeev mus rau qhov ua haujlwm.
Kauj ruam 2
Laij xyuas lub hwj chim tswj tau los ntawm kev xa xov rau koj daim ntawv thov tshwj xeeb. Cov tswj fais fab tau muab faib ua cov hluav taws xob txuas: lub zog loj (lub zog xa hluav taws xob), lub zog nruab nrab (tsis tshaj 100 W) thiab qis zog (txog 25 W).
Kauj ruam 3
Tshawb nrhiav ntev npaum li cas nws yuav siv sij hawm rau cov kev txuas mus ntxiv, uas yog, dab tsi yuav yog lub sijhawm nruab nrab ntawm lub sijhawm ntawm lub teeb liab thov thiab pib ntawm nws cov nyhuv ncaj qha rau hauv Circuit Court. Relays rau hom kev yam ntxwv no tau muab faib ua lub sijhawm xa mus, ncua rov ua dua thiab rov qab xa hluav taws xob.
Kauj ruam 4
Them nyiaj tshwj xeeb thaum xaiv qhov tsim heev ntawm lub relay, txij li thaum lub zog tseem yuav ntseeg nws. Saib cov yam ntxwv uas cuam tshuam nrog qhov tsis zoo ntawm lub cuab yeej no, uas yog: qhov loj ntawm cov khoom siv tshuab, qhov nrawm ntawm kev ua haujlwm, tus nqi cuam tshuam thaum lub sijhawm Circuit Court, qhov nyiaj ntawm cov khoom siv hluav taws xob. Saib dab tsi yog tus nqi ntawm qhov kev khiav hauj lwm voltage hauv kev xa rov qab winding, nws yuav tsum tau sib haum nrog cov ntaub ntawv hauv cov ntaub ntawv pov thawj cov cuab yeej.
Kauj ruam 5
Muab qhov nyiam tso rau cov txuas mus nrog qhov siab siv hluav taws xob ntau. Thaum lub sij hawm luv luv ntawm cov khoom siv hluav taws xob ntau ntxiv rau qhov winding, cov neeg kho tshuab overvoltage yuav tshwm sim hauv pawg sib cuag. Nco ntsoov them sai sai rau tus nqi ntawm cov kev hloov pauv tam sim no thiab tus nqi ntawm cov kev cia siab, lub zog tseem ceeb ntawm kev xa tawm yuav nyob ntawm cov yam ntxwv no.
