Xyuas seb cov khoom siv hluav taws xob puas txuas nrog cov xaim tiv thaiv hauv av. Rau cov khoom siv hluav taws xob uas muaj kev rwb thaiv tsev zoo ntawm cov hlau casing thiab cov khoom siv hluav taws xob, cov hlau casing yuav tsum tau ntsuas thaum lub zog 220V AC txuas nrog ua haujlwm ib txwm. Yog hais tias lub teeb-emitting diode nyob rau hauv lub xeem cwj mem tsis emit lub teeb, nws txhais tau hais tias lub vaj tse ntawm cov khoom siv hluav taws xob txuas nrog ib tug zoo tiv thaiv grounding hlau (los yog txuas nrog lub nruab nrab hlau); Yog hais tias lub teeb-emitting diode nyob rau hauv cov hluav taws xob ntsuas cwj mem glows, nws txhais tau hais tias cov kev tiv thaiv grounding hlau tsis txuas nrog lub vaj tse ntawm cov khoom siv hluav taws xob, los yog cov hlau twb qhib lawm. Txhawm rau kom muaj kev nyab xeeb ntawm tus kheej, yuav tsum muaj kev tiv thaiv zoo hauv av yuav tsum txuas nrog lub tsev ntawm cov khoom siv hluav taws xob raws li qhov xav tau. Nws yuav tsum tau taw qhia rau ntawm no tias thaum kuaj pom lub plhaub hlau ntawm cov khoom siv hluav taws xob, lub teeb-emitting diode hauv qhov ntsuas cwj mem emits teeb. Nws tsis yog tias cov khoom siv hluav taws xob cov khoom siv hluav taws xob tau xau nrog 220V alternating tam sim no, tab sis vim hais tias cov khoom siv hluav taws xob lub casing tsis txuas nrog hauv av xaim, yog li Lub generated tsis muaj zog induced voltage ua rau lub teeb-emitting diode nyob rau hauv lub cwj mem glow brightly. Nyob rau hauv tib txoj kev, ntxig qhov kev sojntsuam ntawm tus cwj mem mus rau hauv qhov chaw tiv thaiv hauv av (lossis tiv thaiv tsis muaj hlau) jack ntawm 220V peb lub qhov hluav taws xob qhov (socket). Yog hais tias lub LED nyob rau hauv lub xeem cwj mem tsis teeb, nws txhais tau hais tias cov kev tiv thaiv grounding hlau (los yog lub nruab nrab hlau) nyob rau hauv zoo. ; Yog hais tias lub teeb-emitting diode glows, nws txhais tau hais tias cov kev tiv thaiv grounding wire jack ntawm lub qhov (socket) tsis zoo, tej zaum yuav yog hais tias tus tiv thaiv grounding hlau tau qhib, los yog cov tiv thaiv grounding hlau yuav tsis txuas.
