I-Thermal Cutoffs kunye ne-Thermal Fuses

I-Thermal cutoffs kunye nezikhuseli ze-thermal aziseti ngokutsha, izixhobo ezibuthathaka kwi-thermal eziyilelwe ukukhusela izixhobo zombane kunye nezixhobo zemizi-mveliso emlilweni. Ngamanye amaxesha zibizwa ngokuba yi-thermal-shot fuses. Xa ubushushu be-ambient bonyuswa ukuya kwinqanaba elingaqhelekanga, i-thermal cutoff ibona utshintsho lobushushu kwaye yaphule isekethe yombane. Oku kufezekiswa xa i-pellet ye-organic yangaphakathi ifumana utshintsho lwesigaba, ivumela abafowunelwa basentwasahlobo ukuba bavule ngokusisigxina isiphaluka.

Iinkcukacha

Ubushushu be-Cutoff yenye yezona zinto zibalulekileyo ekufuneka ziqwalaselwe xa ukhetha i-thermal cutoffs kunye nezikhuseli ze-thermal. Eminye imiba ebalulekileyo ibandakanya:

ukuchaneka kobushushu be-cutoff

I-Voltage

umsinga otshintshanayo (AC)

yangoku ngqo (DC)

Iimbonakalo

I-Thermal cutoffs kunye nezikhuseli ze-thermal (i-fuse-shot enye) ziyahluka ngokwemiqathango:

izinto ezikhokelayo

isimbo sokukhokela

uhlobo lwetyala

iiparamitha zomzimba

Ucingo lobhedu olufakwe kwinkcenkce kunye nocingo lobhedu olufakwe ngesilivere lukhetho oluqhelekileyo kwizinto ezikhokelayo. Kukho iindlela ezimbini eziphambili zokukhokela: i-axial kunye ne-radial. Ngokukhokelela kwi-axial, i-fuse ye-thermal yenzelwe ukuba i-lead enye ihambe ukusuka ekupheleni kwecala. Ngezikhokelo ze-radial, i-fuse ye-thermal iyilwe ukuze zombini izikhokelo zande ukusuka kwelinye icala kuphela. Iimeko ze-thermal cutoffs kunye nabakhuseli be-thermal zenziwe kwii-ceramics okanye i-phenolics. Izinto zeCeramic ziyakwazi ukumelana nokushisa okuphezulu ngaphandle kokuthotywa. Kubushushu obuphakathi, iiphenolics zinamandla okuthelekisa ama-30,000 lbs. Iiparamitha ezibonakalayo zokunqunyulwa kwe-thermal kunye nezikhuseli ze-thermal zibandakanya ubude belothe, ubukhulu becala ubukhulu, kunye nobude bendibano yetyala. Abanye ababoneleli bachaza ubude obongezelelweyo bokukhokela obunokongezwa kubude obuchaziweyo be-cutoff ye-thermal okanye umkhuseli we-thermal.

Usetyenziso

I-Thermal cutoffs kunye nezikhuseli zokushisa zisetyenziswa kwiimveliso ezininzi zabathengi kwaye zithwala amanqaku ahlukeneyo, iziqinisekiso kunye nokuvunywa. Usetyenziso oluqhelekileyo lubandakanya izomisi zeenwele, ii-ayini, iimotor zombane, ii-oveni zemicrowave, iifriji, abenzi bekofu eshushu, oomatshini bokuhlamba izitya, kunye neetshaja zebhetri.
