cov ntaub ntawv dav dav

Muaj ntau yam uas ua rau nws nyuaj rau kev tua hluav taws hauv kev teeb tsa hluav taws xob. Vim lub high voltage, cov extinguishing agents ua conductive thiab re-ignite. Lwm qhov tseem ceeb yog cov ntaub ntawv ntawm cov rwb thaiv tsev cable. Lawv txawv los ntawm siabignition kub thiab muaj peev xwm smolder yam tsis muaj oxygen. Yog li ntawd, cov nplaim hluav taws tuaj yeem rov ua dua tom qab tshem tawm. Cov yam tseem ceeb no yog qhov tseem ceeb rau cov lus nug ntawm hom kev tua hluav taws twg tuaj yeem tua hluav taws xob nrog kev ua haujlwm zoo tshaj plaws.

Hais txog hom tshuaj tua hluav taws

Kev tua hluav taws zoo yuav tsum paub txog hom hluav taws tua hluav taws. Ntawm kev muag khoom yog cov qauv sib txawv ntawm qhov hnyav, qhov loj me, hom ntawm cov khoom siv yooj yim, lub zog ntawm lub zog, thaj tsam ntawm daim ntawv thov, lub hom phiaj, coj mus rau hauv tus account qhov ua rau ignition, tus me nyuam txoj kev, thiab muaj peev xwm rov qab tau. Yuav ua li cas xaiv qhov zoo?

Txhawm rau pib, txhawm rau paub seb lub tshuab tua hluav taws twg tuaj yeem tua hluav taws xob ntawm ntau qhov hluav taws xob, koj yuav tsum ua raws li cov cai luv luv hauv qab no:

• rau cov khoom siv txog 1000 V - hmoov;
• rau cov khoom siv txog li 10000 V - carbon dioxide;
• rau cov khoom siv txog li 1000 V - carbon dioxide yog tias: muaj dej hauv carbon dioxide vapor yog los ntawm 0.006% thiab siab dua, thiab qhov ntev ntawm lub dav hlau tua hluav taws yog tsawg dua 3 meters.

Cov khoom ua npuas dej thiab dej tua hluav taws (OV, ORP, OCP) yog qhov tsim nyog rau kev tua hluav taws tua hluav taws xob de-energized. Kev tso cai siv lawv tuaj yeem tau txais los ntawm cov ntawv tso cai ntawm cov khoom siv hluav taws xob raws li kev pom zoo ntawm qhov hluav taws xob thiab kev cuam tshuam ntawm cov khoom siv hluav taws xob. Lub dav hlau ntawm cov dej los yog ua npuas ncauj yuav tsum tau qhia meej meej ntawm qhov chaw ntawm qhov hluav taws kub, thiab tsis yog ntawm kev sib kis.nplaim taws. Cia peb xav txog qhov twg cov hluav taws tua hluav taws tuaj yeem tua hluav taws hauv cov khoom siv hluav taws xob (hauv qhov hluav taws xob), nrog rau qhov muaj feem ntawm qhov hu ua residual voltage. Yog tias nws tsis tuaj yeem de-energize lub network, nws tsuas yog tso cai siv lub tshuab tua hluav taws uas muaj qhov cim "E" ntawm lub cev, tsim nyog rau kev tshem tawm cov xwm txheej ntawm kev teeb tsa hluav taws xob.

dej

Lawv qhov kev txiav txim yog ua raws li kev txau lossis muab dej hauv daim ntawv ntawm lub dav hlau siab. Nrog lawv cov kev pab, lawv tshem tawm qhov hluav taws kub ntawm cov ntaub ntawv xws li ntawv, yas. Cov khoom kub hnyiab yuav tsum tau kho nrog lub dav hlau qhia dej. Lub tshuab tua hluav taws zoo li cas rau kev tua hluav taws xob, yog tias qhov hluav taws kub ntawm cov kua hluav taws xob tsis suav nrog? Cov tshuaj ua kua raug tso cai kom tua tau tsuas yog los ntawm kev txau cov tee xwb, thiaj li tsis ua rau lawv tawg, thiab cov dej muaj pes tsawg leeg yuav tsum muaj cov khoom tshwj xeeb ntxiv.

Ua npuas dej tua hluav taws ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev thaiv kev nkag mus ntawm cov pa oxygen, tsim nyog rau kev tua cov kua thiab cov khoom siv hluav taws xob thiab tsim nyog rau thaj chaw me me, nyob rau hauv ib lub vojvoog ntawm ib lub 'meter'. Cov kev cai txwv tsis pub tua hluav taws xob thiab cov khoom siv uas muaj cov poov tshuaj, sodium, txij li thaum lawv cuam tshuam nrog ua npuas ncauj, oxygen raug tso tawm, uas txhawb kev combustion.

Cov khoom no tsim nyog rau kev tua hluav taws hauv kev teeb tsa hluav taws xob nyob rau hauv qhov hluav taws xob, thaum cov hlau tsis yog hlau ignite. Lawv txawv los ntawm qhov zoo ntawm lub dav hlau uas tsis tshua muaj kub thiab muaj nyob rau hauv hom roj. Txwv tsis pub sivCov hluav taws tua hluav taws carbon dioxide nyob rau hauv qhov chaw kaw, thiab tseem muaj kev pheej hmoo ntawm kev raug mob ntawm daim tawv nqaij los ntawm kev kov lub tswb ntawm qhov kub thiab txias. Cov tshuaj tua hluav taws carbon dioxide muaj txiaj ntsig zoo rau cov khoom, kua, gaseous tshuaj thiab tua cov xov hlau. Tom qab siv cov khoom no, tsis muaj qhov seem tshuav, tab sis qhov muaj peev xwm ntawm kev siv hauv thaj chaw txwv yog nws qhov tsis zoo: cov pa roj carbon dioxide ntau hauv chav tuaj yeem ua rau lom.
