Kev tiv thaiv kev ntsuas ntawm cov khoom sib txuas tsis muaj dej yog qhov tseem ceeb ntawm nws lub peev xwm tiv taus dej thiab plua plav, feem ntau qhia siv Ingress Protection (IP) ntsuas qhov system. Kev ntsuas IP muaj ob tus lej: thawj qhia txog qib ntawm kev tiv thaiv cov khoom siv (plua plav), thiab qhov thib ob qhia txog qib kev tiv thaiv dej. Kev ntsuas siab dua qhia tias muaj kev tiv thaiv zoo tshaj plaws tiv thaiv cov khoom sab nraud thiab cov dej noo, ua rau cov khoom lag luam ua haujlwm zoo hauv qhov xav tau ntau dua.
Cov kev ntsuas feem ntau rau cov khoom sib txuas tsis muaj dej muaj xws li IP65, IP66, IP67, thiab IP68. IP65- ntsuas cov khoom sib txuas tiv thaiv plua plav nkag thiab tiv taus qis- cov dav hlau dej siab; IP66- cov khoom ntsuas ntsuas muaj kev tiv thaiv dej zoo, muaj peev xwm tiv taus cov dej ntws muaj zog; IP67-rated connectors tseem ua haujlwm thaum lub sij hawm luv luv rau hauv dej; thiab IP68-rated khoom muab cov qib siab tshaj plaws ntawm kev tiv thaiv, ua tau raws li qhov xav tau ntawm qhov chaw hnyav xws li submersion mus ntev.
Kev tiv thaiv sib txawv yog haum rau cov ntawv thov tshwj xeeb. Piv txwv li, cov cuab yeej siv sab nraum zoov thiab cov teeb pom kev zoo feem ntau siv cov khoom siv IP65 lossis IP66-rated, thaum cov khoom siv hauv qab dej, cov tshuab hluav taws xob tshiab, thiab cov chaw lag luam uas muaj kev tiv thaiv nruj raws li IP67 lossis IP68-rated khoom. Xaiv qhov kev tiv thaiv tsim nyog tau txais txiaj ntsig zoo txhim kho cov cuab yeej ua haujlwm ruaj khov thiab txuas ntxiv lub neej kev pab cuam.
Nrog rau kev nce qib ntawm cov khoom siv hauv kev lag luam thiab cov thev naus laus zis ntse, kev lag luam xav tau rau siab - tiv thaiv cov khoom sib txuas txuas ntxiv nce ntxiv. Thaum lub sij hawm tsim thiab tsim, tuam txhab uas muag yuav tsum xaiv tsim sealing qauv thiab cov ntaub ntawv raws li lub hom phiaj kev khiav hauj lwm ib puag ncig los xyuas kom meej kev ruaj ntseg kev tiv thaiv thiab muab kev ruaj ntseg, ruaj khov connectivity rau cov khoom.
