Emkhakheni wobunjiniyela bakagesi nesilinganiso, ukunemba kubaluleke kakhulu. Enye yezingxenye ezibalulekile ezisiza ukulinganisa okunembile kwamanje yi-shunt resistor. Phakathi kwezinto ezahlukahlukene ezisetshenziselwa ama-shunts, iManganin igqama ngenxa yezakhiwo zayo ezihlukile. Lesi sihloko sidingida ukuthi yiniUManganin uyashuntskukhona, izinto ezisetshenziselwa ama-shunts, kanye nezicelo zazo ezithile.
Iyini i-Shunt?
I-shunt iyingxenye yokumelana okuphansi ebekwa ngokuhambisana nedivayisi yokulinganisa, njenge-ammeter, ukuvumela ukukalwa kwamaza aphezulu ngaphandle kokulimaza ithuluzi. Ngokusebenzisa umthetho we-Ohm, ukwehla kwamandla kagesi kuyo yonke i-shunt kungalinganiswa, okubese kusetshenziselwa ukubala amandla amanje agelezayo kumjikelezo.
Iyiphi Impahla Esetshenziselwa I-Shunt?
Ama-shunt resistors angenziwa ngezinto ezahlukahlukene, ngayinye inikezela ngezinzuzo ezihlukile kanye nokubi. Izinto ezijwayelekile zifaka:
I-Copper: Eyaziwa ngokusebenza kwayo okuhle kakhulu, ithusi livame ukusetshenziswa ekusetshenzisweni okuphansi kwamanje. Kodwa-ke, ukuthambekela kwayo ku-oxidation kungaholela ekungalungisweni kwesikhathi.
I-Nickel: Ama-nickel shunts aqinile futhi amelana nokugqwala, okuwenza afanelekele izindawo ezinokhahlo. Nokho, awahambisani njengethusi.
I-Manganin: Lena ingxubevange eyakhiwe ngokuyinhloko yethusi, i-manganese, ne-nickel. I-Manganin ithandwa kakhulu ekusetshenzisweni kwe-shunt ngenxa ye-coefficient yayo yokushisa ephansi yokumelana, okusho ukuthi ukumelana kwayo kushintsha kancane kakhulu ngokushintshashintsha kwezinga lokushisa. Lokhu kuzinza kubalulekile ezilinganisweni ezinembile.
I-Constantan: Enye i-alloy, ngokuyinhloko yethusi ne-nickel, i-Constantan ivame ukusetshenziswa kuma-thermocouples nama-shunts ngenxa yokuzinza kwayo okuhle nokumelana ne-oxidation.
Isetshenziselwani iManganin Shunt?
UManganin uyashuntszisetshenziswa kabanzi ezinhlelweni ezahlukahlukene ngenxa yezakhiwo zazo ezihlukile. Nazi ezinye zezindlela eziyinhloko zokusetshenziswa:
Isilinganiso Samanje Sokunemba: Ama-Manganin shunts avame ukusetshenziswa kuma-ammeters nakwamanye amadivaysi okulinganisa lapho kudingeka khona ukunemba okuphezulu. I-coefficient yabo yokushisa ephansi iqinisekisa ukuthi ukumelana kuhlala kuzinzile, kunikeze ukufundwa okuthembekile.
Amazinga Wokulinganisa: Kulabhorethri, ama-Manganin shunts avame ukusetshenziswa njengamazinga okulinganisa amanye amathuluzi okulinganisa. Ukuziphatha kwabo okubikezelwayo ngaphansi kwezimo ezihlukene kubenza balungele le njongo.
Ukulinganisa Amandla: Ezinhlelweni zamandla, ama-Manganin shunts asetshenziselwa ukukala amaza amakhulu ngaphandle kokwethula ukwehla kwamandla kagesi abalulekile. Lokhu kubalulekile ukuze kugcinwe ukusebenza kahle kwesistimu nokuphepha.
Izicelo Zezimboni: Ama-Manganin shunts asetshenziswa ezinhlelweni ezihlukene zezimboni, okuhlanganisa amasistimu okulawula izimoto namanethiwekhi okusabalalisa amandla, lapho ukukalwa okunembile kwamanje kubalulekile ekusebenzeni kahle.
Ucwaningo Nokuthuthukiswa: Kuzilungiselelo ze-R&D, ama-Manganin shunts asetshenziswa ekusetheni kokuhlolwa lapho izilinganiso zamanje ezinembile zidingeka ukuze kuqoqwe idatha nokuhlaziywa.
Isiphetho
UManganin uyashuntszimelela ingxenye ebalulekile emkhakheni wokulinganisa kagesi. Izakhiwo zazo eziyingqayizivele zezinto ezibonakalayo, ikakhulukazi i-coefficient yazo ephansi yezinga lokushisa lokumelana, zizenza zilungele izinhlelo zokusebenza ezidinga ukunemba okuphezulu nokuzinza. Kungakhathaliseki ukuthi kuzilungiselelo zezimboni, amalabhorethri, noma amasistimu kagesi, ama-Manganin shunts adlala indima ebalulekile ekuqinisekiseni ukuthi izilinganiso zikagesi zinokwethenjelwa futhi zinembile. Njengoba ubuchwepheshe buqhubeka buthuthuka, ukubaluleka kokulinganisa kwamanje okunembile kuzokhula kuphela, kuqinise indima ye-Manganin shunts kubunjiniyela besimanje bukagesi.
