1. Thaum lub melts melts, ua tib zoo txheeb xyuas qhov ua rau fusing.Tej yam ua tau yog:
(1) luv Circuit Court txhaum los yog overload ib txwm fusing;
(2) Lub sijhawm ua haujlwm ntawm cov yaj yog ntev dhau lawm, thiab cov yaj yog tawg los ntawm kev ua yuam kev vim oxidation lossis kub kub thaum ua haujlwm;
(3) Lub yaj yog mechanically puas thaum lub sij hawm installation, uas txo nws cov seem cheeb tsam thiab ua rau tsis tseeb puas thaum lub sij hawm ua hauj lwm.
2. Thaum hloov cov yaj, nws yuav tsum:
(1) Ua ntej txhim kho lub yaj tshiab, nrhiav kom paub qhov ua rau yaj fusing.Yog tias qhov ua rau yaj fusing tsis paub meej, tsis txhob hloov cov yaj rau kev sim khiav;
(2) Thaum hloov cov yaj tshiab, xyuas seb tus nqi ntawm cov yaj puas phim cov cuab yeej tiv thaiv;
(3) Thaum hloov cov yaj tshiab, xyuas qhov kub hnyiab ntawm lub raj fuse.Yog tias muaj mob hnyav, hloov lub raj fuse tib lub sijhawm.Thaum cov porcelain melting yeeb nkab puas lawm, nws tsis raug tso cai siv lwm cov ntaub ntawv los hloov nws.Thaum hloov cov packing fuse, xyuam xim rau lub ntim.
3. Kev tu ua haujlwm thaum lub fuse tsis ua haujlwm yog raws li hauv qab no:
(1) Tshem tawm cov plua plav thiab xyuas qhov kev sib cuag ntawm qhov chaw tiv tauj;
(2) xyuas seb lub fuse zoo li cas (tshem tawm lub fuse tube) puas lossis deformed, thiab seb cov plooj (porcelain) puas muaj cov cim flicker;
(3) Tshawb xyuas seb lub fuse thiab yaj puas sib haum nrog cov tiv thaiv Circuit Court lossis khoom siv, thiab tshawb xyuas raws sijhawm yog tias muaj teeb meem;
(4) Tshawb xyuas N kab hauv TN grounding system thiab cov khoom siv tiv thaiv hauv av, thiab tsis txhob siv cov fuses;
(5) Thaum lub sijhawm tu thiab tshuaj xyuas ntawm lub fuse, lub zog hluav taws xob yuav tsum raug txiav tawm raws li cov kev cai ntawm kev nyab xeeb, thiab lub raj fuse yuav tsum tsis txhob muab tawm nrog hluav taws xob.
