Kuma-elekthronikhi, ama-resistor adlala indima ebalulekile ekulawuleni ukugeleza kwamandla kagesi. Ayingxenye ebalulekile kumadivayisi asukela kumasekethe alula kuya emishinini eyinkimbinkimbi. Izinto ezisetshenziswa ukukhiqiza ama-resistor zithinta kakhulu ukusebenza kwawo, ukuqina kanye nokusebenza kahle. Phakathi kwawo, ama-alloy ensimbi-chromium-aluminium, ama-alloy e-nickel-chromium, kanye nama-alloy ethusi-nickel athakazelisa kakhulu ngenxa yezakhiwo zawo ezihlukile.
Kungani ama-alloy edlala indima ebalulekile ekukhiqizweni kwama-resistor
Ama-alloy ayingxube yezinto ezimbili noma ngaphezulu, okungenani eyodwa yazo eyinsimbi. Aklanywe ukuze athuthukise izakhiwo ezithile ezifana namandla, ukumelana nokugqwala kanye nokuqina kokushisa. Ekusetshenzisweni kwama-resistor, ukukhetha i-alloy kuthinta i-coefficient yokushisa, ukuzinza kanye nokusebenza okuphelele kwe-resistor.
Yiziphi izici ezibalulekile zama-alloy asetshenziswa kuma-resistor
(1) Ukumelana: Umsebenzi oyinhloko we-resistor ukunikeza ukumelana nokugeleza kombane. Ukumelana kwe-alloy kuyisici esibalulekile ekunqumeni ukusebenza kwayo ekwenzeni lo msebenzi. 2.
(2) I-Temperature Coefficient: Lesi sici sibonisa ukuthi ukumelana kwezinto kuyahlukahluka kangakanani ngokushisa. Ama-resistors adinga i-coefficient yokumelana nokushisa okuphansi ukuqinisekisa ukusebenza okuzinzile emazingeni okushisa ahlukahlukene.
(3) Ukumelana Nokugqwala: Ama-resistors avame ukuchayeka ezindaweni ezinzima. Ama-alloy amelana nokugqwala nokugqwala abalulekile ekugcineni impilo nokuthembeka kwe-resistor.
(4) Amandla Omshini: Ama-resistors kumele amelane nokucindezeleka ngokomzimba kanye nokujikeleza kokushisa. Ama-alloy anamandla aphezulu omshini angamelana nalezi zimo ngaphandle kokuwohloka.
(5) Ukuzinza Kokushisa: Ikhono le-alloy lokugcina izakhiwo zalo emazingeni okushisa aphezulu libalulekile, ikakhulukazi ekusetshenzisweni kwamandla aphezulu.
I-Iron Chromium Aluminium Alloy - Ukwakheka kanye Nezakhiwo:
Ama-alloy e-iron-chromium-aluminium(FeCrAl) zaziwa ngokumelana kwazo okuhle kakhulu nokushiswa kwe-oxidation kanye nokuqina kokushisa okuphezulu. Ngokuvamile zakhiwe ngensimbi, i-chromium kanye ne-aluminium, lezi zinsimbi aziboli kakhulu emazingeni okushisa afinyelela ku-1400°C (2550°F).
Izicelo kuma-Resistors:
Ama-alloy e-iron-chromium-aluminium asetshenziswa kabanzi kuma-resistor okushisa okuphezulu, ikakhulukazi kulezi zicelo ezilandelayo:
- Izinto Zokushisa: I-Iron Chromium Ama-alloy e-aluminium avame ukusetshenziswa njengezinto zokushisa ezithandweni zezimboni nasemahhavini ngenxa yekhono lawo lokugcina ubuqotho besakhiwo emazingeni okushisa aphezulu.
- Ama-resistors kagesi: Lawa ma-alloy asetshenziswa futhi kuma-resistors kagesi adinga ukuzinza okuphezulu kokushisa kanye nokumelana ne-oxidation.
- Izicelo zezimoto: Kuma-elekthronikhi ezimoto, ama-alloy e-FeCrAl asetshenziswa kuma-resistor asebenza ezindaweni ezinokushisa okuphezulu, njengezinhlelo zokukhipha umoya.
Ama-alloy e-Nickel-Chromium - Ukwakheka kanye nezakhiwo:
Ama-alloy e-nickel-chromium (NiCr) angenye indlela ethandwayo yokusetshenziswa kwe-resistor. Lawa ma-alloy ngokuvamile akhiwa yi-nickel ne-chromium, iphesenti lawo lincike ezicini ezifunwayo.Ama-alloy e-NiCrzaziwa ngokumelana kwazo okuhle kakhulu, ukusebenza kahle kwezinga lokushisa eliphezulu kanye nokumelana nokugqwala.
Ama-alloy e-Nichrome avame ukusetshenziswa:
- Ama-Resistors eFilimu: Lawa ma-resistors asetshenziswa ezinhlotsheni lapho ukunemba kubaluleke kakhulu khona nalapho i-NiCr alloy inikeza ukuzinza okudingekayo kanye ne-coefficient yokushisa ephansi.
- Ama-Wirewound Resistor: Kuma-wirewound resistor, i-Nichrome wire ivame ukusetshenziswa ngenxa yokumelana kwayo okuphezulu kanye nekhono layo lokumelana nokujikeleza kokushisa.
- Izicelo Zokushisa Okuphezulu: Njenge-ferrochromium-aluminium alloys, i-nickel-chromium alloys ifaneleka ezindaweni zokushisa okuphezulu, okwenza zibe zilungele ukusetshenziswa kwezimboni kanye nezindiza.
Ama-alloy e-Copper-nickel - ukwakheka kanye nezakhiwo
Ama-alloy e-Copper-nickel (CuNi) aziwa ngokusebenza kwawo kahle kakhulu kukagesi kanye nokumelana nokugqwala. Lawa ma-alloy ngokuvamile aqukethe ithusi ne-nickel, anezakhiwo ezithile ezitholakala ngokushintsha okuqukethwe kwe-nickel. Ama-alloy e-CuNi aziswa kakhulu ngekhono lawo lokugcina ukusebenza ezindaweni zasolwandle nakwezinye izindawo ezigqwalisayo.
Ama-alloy e-Copper-nickel asetshenziswa ezinhlobonhlobo zezicelo zokumelana, okuhlanganisa:
