Kwindawo yobunjineli bombane kunye nokulinganisa, ukuchaneka kubaluleke kakhulu. Enye yezinto ezibalulekileyo eziququzelela umlinganiselo ochanekileyo wangoku yi-shunt resistor. Phakathi kwezixhobo ezahlukeneyo ezisetyenziselwa i-shunts, iManganin ibalasele ngenxa yeempawu zayo ezizodwa. Eli nqaku lijonge kwintoniUManganin uyajikazi, izinto ezisetyenziselwa i-shunts, kunye nezicelo zazo ezithile.
Yintoni iShunt?
I-shunt yicandelo eliphantsi lokuchasana elibekwe ngokuhambelana nesixhobo sokulinganisa, njenge-ammeter, ukuvumela ukulinganiswa kwemisinga ephezulu ngaphandle kokulimaza isixhobo. Ngokusebenzisa umthetho we-Ohm, ukuhla kwe-voltage kwi-shunt kunokulinganiswa, esetyenziselwa ukubala i-current flowing through the circuit.
Yeyiphi imathiriyeli esetyenziselwa iShunt?
I-shunt resistors inokwenziwa kwizinto ezahlukeneyo, nganye inika iingenelo ezahlukeneyo kunye nokungalunganga. Izinto eziqhelekileyo ziquka:
Ubhedu: Eyaziwa ngokuba yi-conductivity egqwesileyo, ubhedu luhlala lusetyenziswa kwizicelo ezisezantsi. Nangona kunjalo, ukuchaphazeleka kwayo kwi-oxidation kunokukhokelela ekungachanekeni ekuhambeni kwexesha.
I-Nickel: I-nickel shunts yomelele kwaye iyamelana nokuhlwa, ibenza bafanelekele indawo ezingqongileyo. Nangona kunjalo, azikho conductive njengobhedu.
IManganin: Le yingxubevange eyenziwe ngobhedu, imanganese, kunye nenickel. I-Manganin ithandwa kakhulu kwizicelo ze-shunt ngenxa yomlinganiso wobushushu obuphantsi wokumelana, okuthetha ukuxhathisa kutshintsha kancinci kakhulu ngokuguquguquka kobushushu. Olu uzinzo lubalulekile kwimilinganiselo echanekileyo.
I-Constantan: Enye i-alloy, ngokuyinhloko yobhedu kunye ne-nickel, i-Constantan idla ngokusetyenziswa kwi-thermocouples kunye ne-shunts ngenxa yokuzinza kwayo kunye nokuchasana ne-oxidation.
Isetyenziselwa ntoni iManganin Shunt?
UManganin uyajikazisetyenziswa ngokubanzi kwizicelo ezahlukeneyo ngenxa yeempawu zazo ezizodwa. Nazi ezinye zeendlela eziphambili zokusetyenziswa:
Ukuchaneka komlinganiselo wangoku: I-Manganin shunts isetyenziswa ngokuqhelekileyo kwii-ammeters kunye nezinye izixhobo zokulinganisa apho ukuchaneka okuphezulu kuyadingeka. I-coefficient yabo yokushisa ephantsi iqinisekisa ukuba ukuchasana kuhlala kuzinzile, kunika ukufundwa okuthembekileyo.
ImiGangatho yoLungiso: Kwiilabhoratri, iiManganin shunts zihlala zisetyenziswa njengemigangatho yokulinganisa kwezinye izixhobo zokulinganisa. Ukuziphatha kwabo okuqikelelweyo phantsi kweemeko ezahlukeneyo kubenza balungele le njongo.
Umlinganiselo wamandla: Kwiinkqubo zamandla, iiManganin shunts zisetyenziselwa ukulinganisa imisinga emikhulu ngaphandle kokwazisa ukuhla kombane okubalulekileyo. Oku kubalulekile ekugcineni ukusebenza kakuhle kwenkqubo kunye nokhuseleko.
Izicelo zoShishino: I-Manganin shunts isetyenziswa kwizicelo ezahlukeneyo zemizi-mveliso, kubandakanywa iinkqubo zokulawula iimoto kunye nothungelwano lokuhambisa amandla, apho umlinganiselo ochanekileyo wangoku ubalulekile ekusebenzeni ngokufanelekileyo.
Uphando kunye noPhuhliso: Kwiisetingi ze-R & D, i-Manganin shunts isetyenziselwa ukuseta uvavanyo apho imilinganiselo yangoku echanekileyo iyimfuneko ekuqokeleleni idatha kunye nohlalutyo.
Ukuqukumbela
UManganin uyajikaukumela icandelo elibalulekileyo kwintsimi yokulinganisa umbane. Iimpawu zabo ezikhethekileyo zezinto eziphathekayo, ngokukodwa i-coefficient yabo yokushisa ephantsi yokumelana, zenza ukuba zilungele izicelo ezifuna ukuchaneka okuphezulu kunye nokuzinza. Nokuba kukwimizi-mveliso, iilabhoratri, okanye iinkqubo zamandla, iiManganin shunts zidlala indima ebalulekileyo ekuqinisekiseni ukuba imilinganiselo yombane inokuthenjwa kwaye ichanekile. Njengoko iteknoloji iqhubela phambili, ukubaluleka komlinganiselo ochanekileyo wangoku kuya kukhula kuphela, ukuqinisa indima yeManganin shunts kubunjineli bombane banamhlanje.
