Kev siv thiab kho cov fuses

1. Thaum lub melts melts, nws yuav tsum tau ua tib zoo txheeb xyuas cov laj thawj ntawm melting, uas tej zaum yuav muaj xws li:
(1) Ib txwm fusing vim yog luv luv Circuit Court txhaum lossis overload ua haujlwm;
(2) Yog tias cov yaj siv ntev dhau lawm, nws yuav tawg vim oxidation lossis kub kub thaum ua haujlwm, ua rau muaj kev hloov pauv ntawm cov yam ntxwv ntawm cov yaj;
(3) Muaj kev puas tsuaj rau cov khoom siv thaum lub sij hawm txhim kho cov yaj, uas txo nws cov ntu ntu ntu thiab ua rau muaj kev sib tsoo thaum lub sijhawm ua haujlwm.
2. Thaum hloov cov yaj, nws yuav tsum:
(1) Ua ntej txhim kho cov yaj tshiab, nws yog ib qho tsim nyog los txheeb xyuas qhov ua rau melting. Yog tias qhov ua rau melting tsis tau txiav txim siab, tsis txhob hloov cov yaj rau kev sim;
(2) Thaum hloov cov yaj tshiab, xyuas seb tus nqi ntawm cov yaj puas phim cov cuab yeej tiv thaiv;
(3) Thaum hloov lub yaj tshiab, nws yog ib qho tsim nyog yuav tsum tau xyuas qhov kub hnyiab ntawm lub raj fuse. Yog tias muaj kev kub nyhiab heev, lub raj fuse yuav tsum tau hloov tib lub sijhawm. Thaum lub porcelain fusion raj puas lawm, nws tsis raug tso cai los hloov nws nrog lwm cov khoom siv raj. Thaum hloov cov yaj ntawm ib hom fuse, yuav tsum tau them nyiaj mloog mus rau lub muab tub lim.
3. Lub fuse yuav tsum tau kho ib txhij nrog lub zog faib khoom:
(1) Ntxuav cov plua plav thiab xyuas qhov kev sib cuag ntawm cov ntsiab lus tiv tauj;
(2) Txheeb xyuas qhov pom ntawm lub fuse (tshem lub fuse tube) rau kev puas tsuaj lossis deformation, thiab xyuas cov khoom siv plooj (porcelain) kom tso cov cim flicker;
(3) Tshawb xyuas seb lub fuse, yaj, thiab tiv thaiv Circuit Court lossis cov khoom sib tw, thiab tshawb xyuas cov teeb meem tam sim ntawd;
(4) Ua tib zoo xyuas cov kab N thiab cov khoom siv hauv av tiv thaiv kab hauv TN grounding system, thiab tsis pub siv cov fuses;
(5) Thaum tswj thiab tshuaj xyuas cov fuses, nws yog ib qho tsim nyog yuav tsum tau txiav tawm lub zog hluav taws xob raws li txoj cai kev nyab xeeb, thiab nws tsis raug tso cai kom tshem tawm lub fuse tube nrog hluav taws xob.
