Yini switch yokushisa?

Ukushintshwa kwamazinga okushisa noma ukushintshwa kwe-thermal kusetshenziselwa ukuvula nokuvala othintana nabo. Isimo sokushintsha sokushintsha izinga lokushisa sishintsha ngokuya ngokushisa kokufaka. Lo msebenzi usetshenziswa njengokuvikelwa kokubheja ngokweqile noma ukugcwala ngokweqile. Ngokuyisisekelo, ukushintshwa kwe-thermal kubhekele ukuqapha izinga lokushisa kwemishini nemishini futhi kusetshenziselwa imikhawulo yokushisa.

Yiziphi izinhlobo zokushintsha okushisa ezikhona?

Ngokuvamile, umehluko wenziwa phakathi kokushintshwa kwemishini kanye ne-elekthronikhi. Ukushintshwa kwamazinga okushisa kwemishini kuhlukahluka kumamodeli ahlukahlukene wokushintsha, njengokushintshwa kokushisa kwe-bimetal kanye nokushintshwa kwamazinga okushisa kwegesi. Lapho kudingeka ukunemba okuphezulu, kufanele kusetshenziswe i-elektroniki lokushisa le-elekthronikhi. Lapha, umsebenzisi angashintsha umkhawulo ukubaluleka ngokwawo bese usetha amaphuzu ambalwa wokushintsha. Ukushintshwa kwesivinini se-bimetal, ngakolunye uhlangothi, kusebenza ngokunemba okuphansi, kepha kuyinkimbinkimbi kakhulu futhi akubizi kakhulu. Enye imodeli yokushintshana yigesi yokushisa igesi yokushisa, esetshenziswa ikakhulukazi kwizicelo ezibucayi zokuphepha.

Uyini umehluko phakathi kokushintsha okuncane kanye nesilawuli sokushisa?

Isilawuli sokushisa singakwazi, sisebenzisa uphenyo lokushisa, nquma izinga lokushisa langempela bese uliqhathanisa nephuzu elisethiwe. Iphuzu elifunekayo lesethi liyalungiswa nge-actuator. Isilawuli sokushisa ngaleyo ndlela sinesibopho sokuboniswa, ukulawula kanye nokuqapha amazinga okushisa. Ukushintshwa kokushisa, ngakolunye uhlangothi, kubangele ukusebenza kokushintsha kuya ngokushisa futhi kusetshenziselwa ukuvula nokuvala imibuthano.

Yini i-bimetal lokushisa switch?

Ukushintshwa kokushisa kwe-bimetal kunquma izinga lokushisa usebenzisa i-disc ye-bimetal. Lezi ziqukethe izinsimbi ezimbili, ezisetshenziswa njengemichilo noma ama-platelet futhi zine-coefficients ehlukile yokushisa. Izinsimbi zivame ukuvela ku-zinc nensimbi noma zethusi nensimbi. Lapho, ngenxa yokushisa okukhona okukhona, izinga lokushisa lokushintsha eliphakeme lifinyelelwa, i-disc ye-bimetal ishintsha ibe yisikhundla sayo esibuhlungu. Ngemuva kokupholisa emuva ekushiseni kabusha kokushintsha kabusha, ukushintshwa kwamazinga okushisa kubuyela esimweni sayo esedlule. Ukushintshwa kwamazinga okushisa ngokuthambisa kagesi, ukunikezwa kwamandla kuyaphazamiseka ngaphambi kokubuyela emuva. Ukuze uzuze imvume ephezulu kusuka komunye nomunye, ama-disc abunjiwe lapho evulekile. Ngenxa yomphumela wokushisa, izimo ze-bimetal decforms ekuqondisweni kwe-convex kanye nezindawo zokuxhumana zingathintana ngokuphepha. Ukushintshwa kokushisa kwe-bimetal kungasetshenziswa njengokuvikelwa okweqile noma njenge-fuse eshisayo.

Ngabe usebenza kanjani i-bimetal switch?

Ukushintshwa kwe-bimetallic kuqukethe imichilo emibili yezinsimbi ezihlukile. Imichilo ye-bimetal ihlanganiswe ndawonye ngokungafani. I-strip iqukethe othintana naye kanye nokunye ukuxhumana ku-bimetal strip. Ngokugoba imichilo, ukushintshwa kwesenzo se-snap kuyasiza, okwenza umjikelezo akwazi ukuvulwa futhi avale futhi inqubo isiqaliwe noma yaphela. Kwezinye izimo, ukushintshwa kwamazinga okushisa kwe-bimetal akudingi ukushintshwa kwesenzo se-snap, njengoba amaplayithi asevele egobile ngokufanele futhi ngaleyo ndlela avele anesenzo se-snap. Ukushintshwa kwe-bimetal kusetshenziswa njengama-thermostat kuma-autory circuit breakers, irons, imishini yekhofi noma ama-heater alande.
