Dab tsi yog chav kawm 2, chav kawm II thiab LPS? Dab tsi yog qhov txawv ntawm chav kawm I thiab chav kawm II?
Chav Kawm I: Cov khoom siv uas tiv thaiv hluav taws xob tau ua tiav los ntawm kev siv hluav taws xob thaiv qhov tseem ceeb thiab tseem muab txoj hauv kev txuas mus rau lub ntiaj teb tiv thaiv tus neeg tiv thaiv hauv lub tsev uas los ntawm kev xa cov khoom seem uas tsis muaj peev xwm kwv yees cov teeb meem hluav taws xob rau hauv av yog tias qhov pib rwb thaiv tsev tsis ua haujlwm. Qhov no txhais tau tias hoob I SPS yuav muab lub davhlau ya nyob twg / tus pin rau kev sib txuas hauv av.
Chav Kawm II: Khoom siv nyob rau hauv uas tiv thaiv hluav taws xob tsis yog cia siab rau qhov yooj yim rwb thaiv tsev xwb, tab sis nyob rau hauv uas muaj kev tiv thaiv kev nyab xeeb ntxiv, xws li ob chav rwb thaiv tsev lossis kev tiv thaiv tiv thaiv kev tiv thaiv tau muab, tsis muaj kev cuam tshuam los ntawm kev tiv thaiv lub ntiaj teb lossis cov teeb tsa kev teeb tsa. Qhov no txhais tau tias hoob II SPS TSIS muaj lub davhlau ya nyob twg / tus pin rau lub ntiaj teb kev sib txuas.
LPS: Thaum hluav taws xob hluav taws xob tau siv los ntawm qhov txwv tsis pub siv hluav taws xob (LPS), nws cov khoom tawm tam sim no thiab lub zog tau nyob hauv qhov txwv tsis pub dhau IEC60950-1 Cov Lus 2B, thiab qhov pheej hmoo ntawm hluav taws tuaj yeem txo qis. Yog li, qhov kev nyab xeeb ntawm qhov chaw nyob nyab xeeb thiab kev ntsuas phom ntawm cov tuaj yeem tuaj yeem qis dua. Yog li ntawv, cov ntaub thaiv yas ntawm cov khoom siv fais fab no tuaj yeem siv HB kev ua kom tawv los txo nqi. Cov ntsiab lus no yog los ntawm ITE cov khoom (IEC / EN / UL60950-1).
Chav Kawm 2: Thaum hluav taws xob hluav taws xob tau txhawb los ntawm chav kawm 2, nws cov khoom tso tawm tam sim no thiab lub zog nyob hauv qab qhov txwv uas pom hauv UL1310 Rooj 30.1, thiab qhov pheej hmoo ntawm hluav taws tuaj yeem txo qis. Yog li, qhov kev nyab xeeb ntawm qhov chaw nyob nyab xeeb thiab kev ntsuas phom ntawm cov tuaj yeem tuaj yeem qis dua. Yog li ntawv, cov ntaub thaiv yas ntawm cov khoom siv fais fab no tuaj yeem siv HB kev ua kom tawv los txo nqi. Kev txhais cov ntsiab lus no los ntawm UL chav 2 fais fab ua haujlwm (UL1310).
