I. Ib txwm cua sov
Circuit Court breakers, terminals, thiab cov xaim nyob rau hauv ib lub thawv xa khoom yuav ua kom muaj cua sov vim yog qhov tsis kam thaum tam sim no ntws los ntawm lawv. Cua sov nyob rau hauv qhov kev txwv tau txais yog ib txwm:
1. Kev xav sov so, kwv yees li 35-40 degree: Thaum tam sim no ntws los ntawm cov hluav taws xob hluav taws xob thiab cov xov hlau hauv lub thawv xa khoom, Joule cua sov yuav raug tsim tawm vim yog tus neeg xyuas pib ua haujlwm thiab tiv thaiv kev tiv thaiv. Thaum cov khoom siv hluav taws xob muaj zog xws li cua txias, qhov cub, thiab lub tshuab hluav taws xob siv hluav taws xob hauv tsev, qhov kub thiab txias ntawm lub thawv yuav yog 10-20℃siab dua qhov kub thiab txias, thiab sab nrauv yuav hnov mob me ntsis rau qhov kov. Qhov no yog ib txwm ua haujlwm.
2. Cov Cuab Yeej Cuab Yeej Cuab Yeej ntawm Ntau Cov Ntsiab Lus: Qhov kub ntawm txhua qhov hloov pauv thiab cov ntsiab lus txuas txuas yog qhov zoo ib yam; tsis muaj ib qho taw tes tshwj xeeb yog kub.
II. Overheating txawv txav
Ib qho xwm txheej hauv qab no qhia tau tias muaj kev ua haujlwm tsis zoo thiab yuav tsum tau tshawb xyuas tam sim:
1. Kub heev rau qhov kov: Lub nraub qaum ntawm koj txhais tes xav tias kub heev uas koj xav rub rov qab, qhia tias qhov kub siab tshaj 70 degree. Qhov no feem ntau txhais tau hais tias overload los yog kev sib cuag tsis zoo.
2. Cov cheeb tsam kub kub tseem ceeb: Cov kab hluav taws xob sab saud lossis qis ntawm ib qho kev hloov pauv kub heev, thaum lwm qhov chaw yog qhov qub. Qhov no yog ib qho cim qhia ntawm xoob xaim screws los yog xoob xaim crimping.
3. Kev kub hnyiab los yog cov ntxhiab tsw yas: Qhov no yog lub teeb liab txaus ntshai tias cov khoom siv rwb thaiv tsev yog decomposing vim cua sov.
4. Nrog suab nrov txawv txav: hnov ib lub suab "buzzing" lossis "ticking" tawm suab yuav qhia tau tias muaj kev sib cuag sab hauv.
5. Discoloration los yog Deformation ntawm lub thawv los yog vaj huam sib luag: Yellowing los yog deformation ntawm cov yas vaj huam sib luag qhia tau hais tias ntev overheating.
III. Muaj peev xwm txaus ntshai thiab kev phom sij
Thaum lub thawv xa khoom nyob rau hauv lub xeev overheated rau lub sijhawm ntev, nws tuaj yeem ua rau muaj ntau yam kev phom sij zais:
1. Cov cuab yeej siv nrawm nrawm: kub kub ua rau lub neej luv luv ntawm cov khoom siv sab hauv, ua rau rwb thaiv tsev laus, brittleness, thiab txawm tawg.
2. Ua rau cov cuab yeej tsis ua haujlwm: Kev kub dhau tuaj yeem ua rau lub zog hluav taws xob tsis ruaj khov, ua rau cov khoom siv hluav taws xob ntau dhau los lossis ua rau cov cuab yeej tiv thaiv kev ua haujlwm tsis zoo, cuam tshuam rau kev tiv thaiv ib puag ncig.
3. Ua rau hluav taws xob hluav taws xob: Qhov no yog qhov tshwm sim loj tshaj plaws. Lub sijhawm ntev overheating yog ib qho ntawm cov laj thawj tseem ceeb ntawm hluav taws xob hluav taws xob. Cov ntaub ntawv pov thawj qhia tau tias hluav taws kub los ntawm hluav taws xob tsis raug cai suav txog 32.3% ntawm tag nrho cov hluav taws kub hauv lub tebchaws, nrog rau cov hluav taws xob hluav taws xob tsis raug suav nrog ntau dua 60% ntawm cov no.
