PTC thermistor alloy waya na-achọta ngwa n'akụkụ dị iche iche n'ihi njirimara ya pụrụ iche. Nke a bụ ụfọdụ ngwa a na-ahụkarị nke thermistors PTC:
Nchedo n'ofe oge: A na-eji thermistors PTC eme ihe na sekit eletriki maka nchebe n'ofe. Mgbe elu dị elu na-agafe na PTC thermistor, okpomọkụ ya na-abawanye, na-eme ka nguzogide na-ebili ngwa ngwa. Mmụba a na-eguzogide na-egbochi usoro nke ugbu a, na-echebe sekit site na mmebi n'ihi oke oke ugbu a.
Nhụta okpomọkụ na njikwa: A na-eji thermistors PTC dị ka ihe mmetụta okpomọkụ na ngwa dị ka thermostats, usoro HVAC, na ngwaọrụ nlekota okpomọkụ. Nguzogide nke thermistor PTC na-agbanwe na okpomọkụ, na-enye ya ohere ịghọta nke ọma ma tụọ mgbanwe okpomọkụ.
Ndị na-ekpo ọkụ na-achịkwa onwe ha: Ndị na-ekpo ọkụ PTC na-arụ ọrụ na ihe ndị na-ekpo ọkụ na-edozi onwe ha. Mgbe eji na kpo oku, PTC thermistor na-eguzogide na-abawanye na okpomọkụ. Ka okpomọkụ na-ebili, nkwụsị nke PTC thermistor na-abawanye, na-eduga n'ibelata mmepụta ike na igbochi ikpo ọkụ.
Mmalite na nchedo moto: A na-eji PTC thermistors na sekit na-amalite moto iji gbochie oke inrush dị ugbu a n'oge mmalite moto. Thermistor PTC na-arụ ọrụ dị ka ihe mgbochi dị ugbu a, jiri nwayọọ nwayọọ na-abawanye nguzogide ya ka ọ na-aga ugbu a, si otú ahụ na-echebe moto site na oke ugbu a na igbochi mmebi.
Nchekwa mkpọ batrị: PTC thermistors na-arụ ọrụ na ngwugwu batrị iji kpuchido ya pụọ na nchaji na ọnọdụ nfefe. Ha na-eme dị ka ihe nchekwa site n'igbochi ọsọ ugbu a na igbochi oke okpomọkụ, nke nwere ike imebi mkpụrụ ndụ batrị.
Mmachi inrush dị ugbu a: Ndị na-ekpo ọkụ PTC na-eje ozi dị ka ndị na-egbochi ọkụ ugbu a na akụrụngwa ọkụ na ngwaọrụ eletrọnịkị. Ha na-enyere aka belata mbido mbụ nke ugbu a na-eme mgbe agbanyere ọkụ ọkụ, na-echebe ihe ndị ahụ na imeziwanye ntụkwasị obi usoro.
Ndị a bụ naanị ọmụmaatụ ole na ole nke ngwa ebe PTC thermistor alloy waya na-eji. Ngwa a kapịrị ọnụ na nleba anya imewe ga-ekpebi kpọmkwem ihe mejupụtara alloy, ụdị ụdị, na paramita arụ ọrụ nke thermistor PTC.
