Dielectric hnab looj tes - ib qho txhais tau tias tiv thaiv tam sim no thaum ua haujlwm nrog cov khoom siv hluav taws xob. Lawv yog tsim los ntawm cov roj hmab tshwj xeeb, uas suav nrog cov khoom uas muab cov khoom elasticity thiab lub zog hluav taws xob, txawm li cas los xij, cov khoom zoo li no yuav tawg nyob rau hauv qhov kev txiav txim ntawm cov roj, roj av, cua sov los yog mechanical stress.
Dielectric hnab looj tes raws li lawv lub hom phiaj yog ob hom:
- Tsim nyog siv rau hauv cov khoom siv hluav taws xob uas qhov hluav taws xob tsis tshaj 1000 V.
- Tsim nyog rau kev teeb tsa hluav taws xob uas qhov hluav taws xob siab dua 1000 V. Nyob rau hauv rooj plaub no, cov hnab looj tes dielectric ua ib qho kev tiv thaiv ntxiv thaum ua haujlwm nrog cov khoom siv kev nyab xeeb yooj yim (cov ntsuas hluav taws xob siab, rods, tiv thaiv thiab hluav taws xob clamps, thiab lwm yam..)
Yog tsis muaj kev siv cov cuab yeej tiv thaiv ntxiv, ib qho khoom siv cais tawm yog siv thaum ua haujlwm nrog cov disconnector drives, Circuit Court breakers thiab lwm yam khoom siv uas qhov voltage ntau dua 1000 V.
Yuav ua li no, cov hnab looj tes tau hnav mus rau qhov tob tob,rub lub tes tsho ntawm cov khaub ncaws. Twb tsis tau dov lub tswb.
Ntawm kev muag khoom koj tuaj yeem pom ntau hom kev tiv thaiv tus neeg sawv cev no:
- hnab looj tes tsis muaj dielectric;
- seamed;
- ob-toed;
- tsib ntiv tes.
Txawm li cas los xij, muaj tib txoj cai rau txhua hom hnab looj tes:
- lawv ntev yuav tsum yog yam tsawg 350 cm;
- yuav tsum muaj qhov cim;
- hnab looj tes loj yuav tsum yog cov hnab looj tes knitted tuaj yeem hnav hauv qab lawv, piv txwv li, thaum ua haujlwm txias;
- Lub tswb yuav tsum dav kom haum rau lub tes tsho.
Cov hnab looj tes Dielectric: cov yam ntxwv ntawm kev siv
Ua ntej siv, lawv yuav tsum tau ua tib zoo tshuaj xyuas qhov kev puas tsuaj ntawm cov khoom siv, av thiab tsis muaj dej noo, thiab tseem saib xyuas cov punctures: twist lub hnab looj tes ntawm tus ntiv tes.
Txhua lub sijhawm ua ntej siv, cov hnab looj tes dielectric yuav tsum tau kuaj xyuas los ntawm kev sau cov cua kom pom los ntawm qhov uas tuaj yeem ua rau hluav taws xob poob siab.
Tiv thaiv kev puas tsuaj, nws tso cai hnav tawv lossis canvas mittens hla cov hnab looj tes dielectric.
Ib ntus, hnab looj tes yuav tsum tau ntxuav hauv dej xab npum thiab ziab.
Yuav ua li cas kuaj cov hnab looj tes dielectric
Lawv yuav tsum muab tso rau hauv ib da dej sov. Dej kuj tau nchuav rau hauv hnab looj tes. Qhov twgCov dej theem ob sab hauv thiab sab nraud ntawm cov hnab looj tes yuav tsum yog tsib centimeters hauv qab ntawm cov npoo, uas yuav tsum nyob twj ywm qhuav.
Rau ib feeb, qhov ntsuas hluav taws xob ntawm 6 kV yog siv nruab nrab ntawm lub cev ntawm da dej thiab cov electrode, uas yog txo qis hauv hnab looj tes. Yog tias xav tau, nws tuaj yeem ua rau tib lub sijhawm sim ob peb khub ib zaug, tab sis nws yog ib qho tsim nyog los tswj tus nqi tam sim no dhau los ntawm txhua lub hnab looj tes. Nws yuav tsum tsis pub tshaj 6 mA.
Nyob rau hauv rooj plaub ntawm kev tawg lossis tshaj qhov ntsuas tam sim no, cov hnab looj tes raug tso tseg, thiab lawv txoj haujlwm txuas ntxiv raug txwv nruj heev.

Daim ntawv qhia tshuaj tiv thaiv, uas siv tau hnub no, tau pom zoo los ntawm kev txiav txim ntawm Ministry of He alth ntawm Lavxias Federation ntawm Lub Peb Hlis 21, 2014 N 125n. Cov kws kho mob hauv koog tsev kawm ntawv cia siab rau nws thaum muab tshuaj tiv thaiv tom ntej
Hluav taws xob ko taw sov: tshuaj xyuas. Dab tsi yog hom hluav taws xob ko taw sov kom yuav?
Hluav taws xob ko taw sov yog nquag siv nyob rau hauv lub caij ntuj sov tsev, hauv tsheb thiab txawm nyob hauv tsev. Qhov no yog qhov tseem ceeb tshaj plaws ntawm cov cuab yeej saum toj no: ntau yam kev siv, kev ua haujlwm yooj yim thiab kev ntseeg tau. Kuj tseem muaj lub hnab sov tshwj xeeb rau ob txhais ceg.

Vim li cas lub teeb txuag hluav taws xob ntsais? Vim li cas lub teeb txuag hluav taws xob blinking thaum muab tua?
Nyob hauv lub ntiaj teb niaj hnub no, cov neeg siv tau siv lawv lub zog txuag "cov viv ncaus" es tsis txhob siv cov teeb pom kev zoo. Txawm li cas los xij, nrog rau kev yooj yim thiab kev txuag nyiaj hauv kev ua haujlwm ntawm cov khoom siv hluav taws xob zoo li no, cov teeb meem tsis xav tau tshwm sim. Ntawm cov "xav tsis thoob" no feem ntau hu ua lub flashing ntawm lub teeb pom kev zoo tom qab muab nws tawm. Vim li cas lub teeb txuag hluav taws xob ntsais muag?
