Kev xaiv ntawm lub davhlau ya nyob twg blocks yeej ib txwm yog lub ntsiab lus kub! Tsuas muaj qee qhov khoom tsis muaj lossis txawm tias tsis muaj kev yuav khoom. Nws yog ib qho mob taub hau mus yuav cov davhlau ya nyob twg. Cia peb saib, peb tuaj yeem xaiv li cas?
Ua ntej ntawm tag nrho cov, ua ntej xaiv ib hom, koj yuav tsum paub dab tsi hom ntawm lub davhlau ya nyob twg thaiv koj xav tau.
Raws li cov haujlwm ntawm cov terminals: zoo tib yam terminals, kev nyab xeeb terminals, xeem terminals, grounding terminals, ob-txheej terminals, ob-txheej terminals, peb-txheej terminals, ib-input-ob-qhov hluav taws xob terminals, ib-input-three- Qhov hluav taws xob terminals, ob-input-ob-qhov hluav taws xob terminals, Circuit Court breaker terminals, overvoltage tiv thaiv terminals, kos npe terminals, thiab lwm yam.
Muab faib raws li tam sim no: me me tam sim no terminals, siab tam sim no terminals, thiab lwm yam raws li nws cov tsos, nws yuav muab faib ua rail terminals, tsau terminals, PCB terminals, thiab lwm yam.
Tom qab ntawd thaum xaiv, feem ntau xav txog cov ntsiab lus hauv qab no:
① Txawm hais tias cov hlau yuav tsum tau txuas yog tawv los yog mos
② Dab tsi yog qhov ntu ntu ntawm cov hlau hauv square millimeters?
③ Ntau npaum li cas tam sim no thiab voltage ua lub terminals yuav tsum tau tiv taus
④ Ntau qhov txuas yuav tsum raug xaiv, yog tias koj xav tau txuas ob peb lub xov hlau ua ke, siv lub txuas nrog ob peb lub qhov.
