Kushandiswa kwePTC Thermistor
1. Kunonoka kutanga PTC thermistor Kubva kuIt characteristic curve yePTC thermistor, inozivikanwa kuti PTC thermistor inotora nguva yenguva kuti isvike kune yakakwirira yekupikisa mamiriro mushure mekunge magetsi aiswa, uye iyi inononoka hunhu inoshandiswa kunonoka kutanga-up zvinangwa. Kana mota yatanga, inoda kukunda inertia yayo uye simba rekuita remutoro (semuenzaniso, simba rekuita refiriji rinofanirwa kukundwa kana firiji compressor yatangwa), saka mota inoda yazvino uye torque kutanga. Kana kutenderera kwakajairika, kuitira kuchengetedza simba, torque inodiwa ichaderedzwa zvakanyanya. Wedzera seti yemakoiri ekubatsira kumota, inoshanda chete kana yatanga, uye inodimbura kana yakajairika. Batanidza iyo PTC thermistor munhevedzano neyokutanga yekubatsira coil. Mushure mekutanga, iyo PTC thermistor inopinda munzvimbo yakakwira yekupokana kuti ibvise coil yekubatsira, iyo inogona kuita izvi. 2. Overload kudzivirira PTC thermistor PTC thermistor yekudzivirira kwekuremerwa chinhu chekudzivirira chinozvidzivirira uye kupora kubva kune yakajairika tembiricha uye abnormal ikozvino, inozivikanwa se "resettable fuse" uye "gumi zviuru-nguva fuse". Iyo inotsiva yechinyakare fuse uye inogona kushandiswa zvakanyanya kune yakawandisa uye inopisa kudzivirira yemotor, transformers, switching magetsi emagetsi, emagetsi maseketi, etc. PTC thermistors for overload dziviriro kuganhurira kudyiwa mumutsara wese kuburikidza nekukasira kushanduka kwekupokana ukoshi kuderedza yasara ikozvino kukosha. Iyo yechinyakare fuse haigone kupora yega mushure mekunge mutsara wavhuvhuta, uye iyo PTC thermistor yekudzivirira kwekuremerwa inogona kudzoserwa kune pre-dziviriro mamiriro mushure mekunge kukanganisa kwabviswa, uye basa rayo rekudzivirira uye rekudzivirira rinopisa rinogona kuitika kana kukanganisa kuchiitika zvakare. .Sarudza iyo PTC thermistor yekudzivirira yakawandisa seye overcurrent thermal kudzivirira chinhu. Kutanga, simbisa iyo yakanyanya kujairika yekushanda ikozvino yemutsara (kureva, isiri-inoshanda ikozvino yePTC thermistor yekudzivirira kuwanda) uye nzvimbo yekuisa yePTC thermistor yekudzivirira kuwanda (panguva yekushanda kwakajairika). ) Iyo tembiricha yepamusoro-soro, inoteverwa nedziviriro yazvino (kureva, kushanda ikozvino kwePTC thermistor yekudzivirira kuwanda), iyo yakanyanya kushanda voltage, yakayerwa zero-simba rekudzivirira, uye zvinhu zvakaita sehukuru hwezvikamu zvinofanirwawo zvakare. kufungwa. Kana dunhu riri mune yakajairika mamiriro, ikozvino inopfuura nepaPTC thermistor yekudzivirira yakawandisa ishoma pane yakayerwa ikozvino, uye iyo PTC thermistor yekudzivirira yakawandisa iri mune yakajairika mamiriro, ine diki yekupokana kukosha, iyo isingazokanganisa yakajairika kushanda kwedunhu rakachengetedzwa. Apo dunhu rinokundikana uye ikozvino inodarika zvakanyanya kurongeka ikozvino, iyo PTC thermistor yekudzivirira kwekuremedza inongoerekana yapisa uye iri munzvimbo yakakwirira yekudzivirira, ichiita kuti dunhu rive mune imwe nzvimbo "yakasununguka", nokudaro ichidzivirira dunhu kubva pakukuvadzwa.Kana kukanganisa kwabviswa, iyo PTC thermistor yekudzivirira yakawandisa inodzokera zvakare kune yakaderera yekupikisa mamiriro, uye dunhu rinotangazve kushanda kwakajairika. 3. Kudzivirira kupisa kwePTC thermistor Iyo Curie tembiricha yePTC thermistor sensor inobva pa40 kusvika 300°C. Paiyo RT hunhu curve yePTC thermistor sensor, kukwira kwakadzika kweiyo kukosha kwekupokana mushure mekupinda munzvimbo yekuchinja kunogona kushandiswa setembiricha, nhanho yemvura, uye kuyerera kwekunzwa. application. Zvinoenderana nemamiriro ekushisa-asinganzwisisike ePTC thermistors, yakagadzirirwa kushandiswa mukudzivirira kwekupisa uye nguva dzekunzwa tembiricha, uye inoshandiswa mukuchinja magetsi, midziyo yemagetsi (motor, transformers), zvishandiso zvemagetsi (transistors). Iyo inoratidzirwa nehukuru hudiki uye nekukurumidza kupindura nguva. , Nyore kuisa. Kusiyana pakati pePTC neKTY:Siemens inoshandisa KTY Chekutanga, iwo rudzi rwemotokari tembiricha kudzivirira mudziyo; PTC inopikisa ine yakanaka tembiricha coefficient, ndiko kuti, kupikisa kukosha kunowedzera sezvo tembiricha inokwira; Imwezve ndeyekuti NTC inochinjika resistor ine yakashata tembiricha coefficient, uye kukosha kwekupikisa kunodzikira sezvo tembiricha inokwira, uye haishandiswe kune general motor dziviriro.KTY ine high precision, yakakwirira kuvimbika uye yakasimba kugadzikana.Inonyanya kushandiswa mumunda wekuyera kwekushisa.KTY yakafukidzwa neyakagadzika yesilicon dioxide insulating material, gomba resimbi rine dhayamita 20mm rinovhurwa pane insulating layer, uye iyo yese yepasi layer yakanyatso simbi.Ikozvino kugoverwa kunoderedzwa kubva kumusoro kusvika pasi kunowanikwa nekurongeka kwemakristasi, saka inonzi diffusion resistance.KTY ine inoshanda in-linear tembiricha coefficient pamusoro pese tembiricha kuyerwa chiyero, nekudaro kuve nechokwadi chepamusoro tembiricha kuyerwa. 
PT100 platinamu inopisa kupisa inogadzirwa uye inogadzirwa nekushandisa iyo yakakosha musimboti wekuti kukosha kwekupokana kwewaya yeplatinamu kunoshanduka nekuchinja kwekushisa. ) uye 100 ohms (nhamba yekupedza kudzidza iPt100), zvichingodaro, tembiricha yekuyera huwandu ndeye -200~850 ℃. Iyo tembiricha inonzwa chinhu chegumi ohm platinamu kupisa kwekudzivirira kunogadzirwa newaya yeplatinamu yakakora, uye tembiricha yekudzivirira kuita zviri pachena kuti yakanaka. 100 ohm platinamu yekupisa kupikisa, chero ichishandiswa munzvimbo yekushisa pamusoro pe650 ℃: 100 ohm platinamu yekupisa kupikisa inonyanya kushandiswa munzvimbo yekushisa iri pasi pe650 ℃, kunyange zvazvo inogona kushandiswa munzvimbo yekushisa inopfuura 650 ℃, asi munzvimbo yekushisa pamusoro pe650 ℃ Kirasi A zvikanganiso hazvibvumirwe. Kugadziriswa kwe100 ohm platinamu kupisa kwekudzivirira kwakakura zvakapetwa kagumi pane iyo yegumi ohm platinamu yekupisa kupikisa, uye zvinodikanwa zvezviridzwa zvechipiri zvinoenderana nekurongeka kwehukuru. Naizvozvo, 100 ohm platinamu kupisa kwekudzivirira kunofanirwa kushandiswa kusvika pazvinobvira pakuyera tembiricha munzvimbo yekushisa iri pasi pe650 °C.
