Ikoreshwa rya PTC Thermistor
1. Gutinda gutangira ubushyuhe bwa PTC Uhereye kuri Iranga umurongo wa thermistor ya PTC, birazwi ko thermistor ya PTC ifata igihe kugirango igere kumurwanya mwinshi nyuma yumuriro wa voltage, kandi uku gutinda kuranga gukoreshwa mugutinda gutangira. Iyo moteri itangiye, igomba gutsinda inertia yayo nimbaraga zogutwara umutwaro (urugero, imbaraga za reaction ya firigo zigomba kuneshwa mugihe compressor ya firigo itangiye), moteri rero ikenera umuyoboro munini na torque kugirango gutangira.Iyo kuzunguruka ari ibisanzwe, kugirango ubike ingufu, urumuri rusabwa ruzagabanuka cyane.Ongeraho urutonde rwibikoresho bifasha kuri moteri, ikora gusa iyo itangiye, kandi igahagarika iyo ari ibisanzwe.Huza thermistor ya PTC murukurikirane hamwe na coil yo gutangira ifasha.Nyuma yo gutangira, thermistor ya PTC yinjira murwego rwo hejuru rwo guhangana na coil yingoboka, ishobora kugera kuriyi ngaruka. 2. Kurenza urugero kurinda PTC thermistor PTC thermistor yo gukingira birenze urugero nikintu cyo gukingira gihita kirinda kandi kigakira ubushyuhe budasanzwe nubushyuhe budasanzwe, bakunze kwita "resettable fuse" na "fuse ibihumbi icumi".Isimbuza fus gakondo kandi irashobora gukoreshwa cyane mukurinda birenze urugero nubushyuhe bukabije bwa moteri, transformateur, guhinduranya amashanyarazi, imiyoboro ya elegitoronike, nibindi. agaciro gasigaye. Fuse gakondo ntishobora gukira ubwayo nyuma yumurongo umaze kuvuzwa, hamwe na thermistor ya PTC yo kurinda imitwaro irenze irashobora gusubizwa muburyo bwokwirinda nyuma yikosa ryakuweho, kandi ibikorwa byayo birenze urugero nuburinzi bwumuriro birashobora kugaragara mugihe amakosa yongeye kubaho .Hitamo PTC thermistor kugirango urinde kurenza urugero nkibintu birinda ubushyuhe bukabije.Ubwa mbere, wemeze ntarengwa isanzwe ikora yumurongo (ni ukuvuga, imiyoboro idakoreshwa ya thermistor ya PTC kugirango irinde kurenza urugero) hamwe nu mwanya wo kwishyiriraho imashini ya PTC yo gukingira birenze (mugihe gisanzwe).) Ubushyuhe bwo hejuru bwibidukikije, bukurikirwa nuburinzi bwo kurinda (ni ukuvuga, imiyoboro ikora ya thermistor ya PTC yo gukingira birenze urugero), imbaraga nyinshi zakazi, imbaraga za zeru zagabanijwe, hamwe nibintu nkubunini bwibigize nabyo bigomba gusuzumwa. Iyo umuzunguruko uri mumiterere isanzwe, ikigezweho kinyura muri thermistor ya PTC kugirango kirinde kurenza urugero kiri munsi yumuvuduko wagenwe, kandi thermistor ya PTC yo kurinda imizigo irenze ibintu bisanzwe, hamwe nagaciro gato ko guhangana, bitazagira ingaruka kuri imikorere isanzwe yumuzingi urinzwe. Iyo umuzenguruko unaniwe kandi umuyaga urenze cyane umuyaga wagenwe, thermistor ya PTC yo kurinda imitwaro irenze urugero irashyuha kandi iri mumwanya wo guhangana cyane, bigatuma umuzunguruko umeze nk '"off", bityo bikarinda umuzunguruko kwangirika.Iyo amakosa akuweho, thermistor ya PTC yo kurinda imitwaro nayo ihita isubira muburyo buke bwo guhangana, hanyuma umuzenguruko ugakomeza gukora bisanzwe. 3. Kurinda ubushyuhe bukabije PTC thermistor Ubushyuhe bwa Curie bwa sensororo ya PTC ni kuva kuri 40 kugeza 300 ° C.Kuri RT iranga umurongo wa sensoriste ya PTC, kuzamuka gukabije kwagaciro kangana nyuma yo kwinjira mukarere kinzibacyuho birashobora gukoreshwa nkubushyuhe, urwego rwamazi, hamwe no kumva ibintu.Porogaramu.Ukurikije ubushyuhe buranga ubushyuhe buranga ubushyuhe bwa PTC, bwashizweho kugirango bukoreshwe mu kurinda ubushyuhe bukabije no mu gihe cyo kumva ubushyuhe, kandi bukoreshwa mu guhinduranya amashanyarazi, ibikoresho by’amashanyarazi (moteri, moteri), ibikoresho by’amashanyarazi (transistors).Irangwa nubunini buto nigihe cyo gusubiza byihuse., Biroroshye gushiraho. Itandukaniro riri hagati ya PTC na KTY:Siemens ikoresha KTY Mbere ya byose, ni ubwoko bwibikoresho byo kurinda ubushyuhe bwa moteri; PTC ni ukurwanya hamwe na coefficient nziza yubushyuhe, ni ukuvuga, agaciro ko guhangana kiyongera uko ubushyuhe buzamuka; Ikindi nuko NTC ari résistoriste ihindagurika hamwe na coefficient yubushyuhe bubi, kandi agaciro kokugabanuka kugabanuka uko ubushyuhe buzamuka, kandi ntibukoreshwa mukurinda moteri rusange.KTY ifite ibisobanuro bihanitse, byiringirwa cyane kandi bihamye.Ahanini ikoreshwa murwego rwo gupima ubushyuhe.KTY itwikiriwe nigice cya silicon dioxyde de insuline, umwobo wicyuma ufite diametero ya 20mm urakingurwa kumurongo wikingira, kandi igice cyo hasi cyose gifite ibyuma rwose.Ikwirakwizwa ryubu ryafashwe kuva hejuru kugeza hasi ryabonetse muburyo bwa kristu, bityo ryitwa diffusion resistance.KTY ifite umurongo ufatika wumurongo wubushyuhe hejuru yubushyuhe bwo gupima ubushyuhe, bityo bigatuma ubushyuhe bwo gupima neza. 
PT100 ya platine irwanya ubushyuhe yateguwe kandi ikorwa hifashishijwe ihame shingiro ryuko agaciro ko kurwanya insinga ya platine ihinduka hamwe nubushyuhe bwubushyuhe.) na 100 oms (umubare wabarangije ni Pt100), nibindi, igipimo cyo gupima ubushyuhe ni -200 ~ 850 ℃.Ubushyuhe bwo kwiyumvamo ubushyuhe bwa 10 ohm platine irwanya ubushyuhe bukozwe mu nsinga nini ya platine, kandi imikorere irwanya ubushyuhe biragaragara ko ari nziza.100 ohm platine irwanya ubushyuhe, mugihe cyose ikoreshwa mukarere k'ubushyuhe hejuru ya 650 ℃: 100 ohm platine irwanya ubushyuhe ikoreshwa cyane cyane muri zone yubushyuhe buri munsi ya 650 ℃, nubwo ishobora no gukoreshwa mubice byubushyuhe buri hejuru ya 650 ℃, ariko muri zone yubushyuhe hejuru ya 650 errors Icyiciro A amakosa ntiyemewe.Ikemurwa rya 100 ohm platine irwanya ubushyuhe irikubye inshuro 10 kurenza iya 10 ya ohm platine irwanya ubushyuhe, kandi ibisabwa kubikoresho bya kabiri bihuye nuburyo bukurikirana.Kubwibyo, 100 ohm platine irwanya ubushyuhe igomba gukoreshwa uko bishoboka kwose kugirango bapime ubushyuhe muri zone yubushyuhe buri munsi ya 650 ° C.
