Mu rwego rwubwubatsi bwamashanyarazi no gupima, ubusobanuro nibyingenzi. Kimwe mu bice byingenzi byorohereza ibipimo nyabyo ni shunt résistor. Mubikoresho bitandukanye bikoreshwa muri shunt, Manganin iragaragara kubera imiterere yihariye. Iyi ngingo iracengera mubyoManganin arirukani, ibikoresho byakoreshejwe shunts, nibisabwa byihariye.
Shunt ni iki?
Shunt ni ikintu gito-kirwanya ibintu gishyizwe hamwe nigikoresho cyo gupima, nka ammeter, kugirango yemererwe gupima imigezi miremire itangije igikoresho. Ukoresheje amategeko ya Ohm, igabanuka rya voltage hejuru ya shunt irashobora gupimwa, hanyuma igakoreshwa mukubara umuyaga unyura mumuzunguruko.
Nibihe bikoresho bikoreshwa muri Shunt?
Kurwanya Shunt birashobora gukorwa mubikoresho bitandukanye, buri kimwe gitanga ibyiza nibibi. Ibikoresho bisanzwe birimo:
Umuringa: Azwiho kuba mwiza cyane, umuringa ukoreshwa mubikorwa bike-bigezweho. Ariko, kwandura kwa okiside birashobora gutuma habaho amakosa mugihe runaka.
Nickel: Nickel shunts iraramba kandi irwanya ruswa, bigatuma ibera ahantu habi. Ariko, ntabwo ziyobora nkumuringa.
Manganin: Uyu ni umusemburo ugizwe ahanini n'umuringa, manganese, na nikel. Manganin itoneshwa cyane cyane kubikorwa bya shunt bitewe nubushyuhe buke bwubushyuhe bwo kurwanya, bivuze ko kurwanya kwayo guhinduka gake cyane hamwe nihindagurika ryubushyuhe. Uku gushikama ni ingenzi kubipimo nyabyo.
Constantan: Undi muti, cyane cyane wumuringa na nikel, Constantan ikoreshwa kenshi muri thermocouples na shunt kubera guhagarara neza no kurwanya okiside.
Niki Manganin Shunt Ikoreshwa?
Manganin arirukazikoreshwa cyane mubikorwa bitandukanye bitewe nimiterere yihariye. Dore bimwe mubikoreshwa byibanze:
Ibipimo bigezweho: Manganin shunts isanzwe ikoreshwa muri ammeter nibindi bikoresho byo gupima aho bisabwa neza. Coefficient yubushyuhe buke yemeza ko kurwanya bikomeza kuba byiza, bitanga ibisomwa byizewe.
Ibipimo bya Calibration: Muri laboratoire, shitingi ya Manganin ikoreshwa nkibipimo bya kalibrasi kubindi bikoresho bipima. Imyitwarire yabo iteganijwe mubihe bitandukanye bituma iba nziza kubwiyi ntego.
Igipimo cy'ingufu: Muri sisitemu z'amashanyarazi, shitingi ya Manganin ikoreshwa mugupima imigezi minini itabanje kwinjiza ingufu za voltage zikomeye. Ibi ni ngombwa mu kubungabunga imikorere ya sisitemu n'umutekano.
Inganda zikoreshwa mu nganda: Shitingi ya Manganin ikoreshwa mubikorwa bitandukanye byinganda, harimo sisitemu yo kugenzura ibinyabiziga hamwe n’imiyoboro ikwirakwiza amashanyarazi, aho ibipimo nyabyo bigezweho ari ngombwa kugirango imikorere ikorwe.
Ubushakashatsi n'Iterambere: Muburyo bwa R&D, shitingi ya Manganin ikoreshwa mugushiraho ubushakashatsi aho ibipimo nyabyo bikenewe kugirango ikusanyamakuru hamwe nisesengura.
Umwanzuro
Manganin arirukabyerekana ikintu cyingenzi murwego rwo gupima amashanyarazi. Ibikoresho byabo byihariye, cyane cyane ubushyuhe buke bwubushyuhe bwo guhangana, bituma biba byiza mubikorwa bisaba ubunyangamugayo buhamye kandi butajegajega. Haba mubikorwa byinganda, laboratoire, cyangwa sisitemu yingufu, shitingi ya Manganin igira uruhare runini mukureba ko ibipimo byamashanyarazi byizewe kandi byuzuye. Mugihe ikoranabuhanga rikomeje gutera imbere, akamaro ko gupima neza neza bizagenda byiyongera gusa, bishimangira uruhare rwa shitingi ya Manganin mubuhanga bugezweho bwamashanyarazi.
