Thermal edluliselwe - idivayisi iphinde Umgomo we operation

inkinobho Thermal kuyinto idivayisi kagesi evikela motor kusuka kunoma iyiphi into yokwenza ezibucayi lokushisa namagugu. Ngezinye izimo umthwalo ephakeme injini okuyisa yimiphi izindlela umshini kagesi noma lisebenze ibusa i esengeziwe ugesi. Lokhu amandla kungaba izikhathi eziningi isicelo imithetho injini. Ngenxa yalokho, sindisa yenqubo ngaphakathi wesifunda kagesi uqala ngokushesha ukwandisa izinga lokushisa. Yiqiniso, bungase buholele umonakalo kule lisebenze. Ukuvimbela lokhu izifunda kagesi zihlanganisa ozikhethela idivayisi ekhethekile yakhelwe kukagesi kwenzeka nganoma yisiphi izindlela eziphuthumayo (transients kumanethiwekhi kagesi, ukuminyana njll). Lokhu kuvikela iyunithi ibizwa ngokuthi edluliselwe ezishisayo (ngezinye izikhathi ungathola igama "thermostat" izincwadi). Umsebenzi oyinhloko we-edluliselwe ezishisayo ukulondoloza imodi esebenzayo ye lisebenze, umthamo yayo jikelele nokusebenza.

I edluliselwe ezishisayo has ipuleti ekhethekile bimetallic e isakhiwo layo langaphakathi. Ngaphansi isenzo overloads futhi overvoltages e inethiwekhi kagesi, ipuleti enjalo uzimisele (sikhubazekile), futhi esimweni salo esivamile it has a ebusweni ngokwanele flat. Lokhu ipuleti bimetallic uvalwe igezwa othintana kagesi, futhi ngenxa yalokho wamanje kungaba ngokukhululekile egeleza circuit kagesi.

Overvoltage nasekuthuthukiseni ukubaluleka kwe-current kagesi yesifunda uqala ngokushesha ukwandisa izinga lokushisa. Lokhu kunomthelela amalahle isici eziyisisekelo edluliselwe ezishisayo - ipuleti ezimbili ungqimba metal. Lesi sakamuva iqala ukugoba futhi evala kugeleta kwemandla, kusukela edluliselwe ezishisayo yakhelwe uyonquma umthwalo futhi voltage lapho ukulayisha amapayipi.

Nokho, i-strip bimetallic kuqeda ngokwanele kancane. Uma yokuxhumana nezinqe ngokuqondile axhunyiwe kuso, aphansi kuka izinga ikwazi ukunikeza eqeda ezenzeka ngesikhathi breaking wesifunda. Ngakho-ke, idivayisi kuyashesha inikezwe ezishisayo edluliselwe design, okubizwa ngokuthi "contact oshaya." Lokho kusho ukuthi kukhethwa edluliselwe ezishisayo kusekelwe emigomweni yayo ezifana Ukusabela isikhathi sincike ubukhulu namandla kagesi.

Uma sicabangela lokhu igebe umsebenzi umshini luzomiswa. Ngemva kwesikhathi esithile (ngokuvamile isigamu sehora - ihora) ipuleti ayaphola bese ubuyela esimweni saso sangaphambilini, lokho, elikhishiwe kwezinye izinguqulo kagesi wesifunda iluphu. Idivayisi kuza emuva isimo ezisebenzisekayo.

edluliselwe Thermal kuyinto ngezinhlobo eziningi. Yande TRP edluliselwe (okwesikhathi single phase umthwalo) TPH (ngoba umthwalo wabantu ababili isigaba), bahlabe umkhosi PTT ezishisayo (i-overload okuqhubekayo circuit ezintathu okhombisa) kanye ezishisayo inkinobho RTL (Ukuvikelwa kwama-motor kagesi ngokumelene sindisa eside).
