Nigute ushobora kumenya intandaro ya transformateur yihuta? Abantu bagura intandaro ya transfert yumurongo mwinshi batinya kugura intoki ikozwe mubikoresho byo hasi. Nigute intangiriro igomba kumenyekana? Ibi bisaba gusobanukirwa uburyo bumwe bwo gutahura intandaro ya aimpinduka nyinshi.
Niba ushaka kumenya intandaro ya transfert yumurongo mwinshi, ugomba no kumenya ibikoresho bikoreshwa mubisanzwe. Niba ubishaka, urashobora kubireba. Hariho byinshi byubwoko butandukanye bwarukuruziibikoresho bikoreshwa mugupima ibintu bya magneti. Kuberako zikoreshwa muburyo butandukanye, hariho ibintu byinshi bigoye bigomba gupimwa. Hariho ibipimo byinshi bitandukanye nuburyo kuri buri kintu, nigice cyingenzi cyo gupima ibintu bya magneti.
Gupima imiterere ya magnetiki ya DC
Ibikoresho bitandukanye byoroshye bya magnetiki bifite ibisabwa bitandukanye byo kugerageza bitewe nibikoresho. Kumashanyarazi yicyuma nicyuma cya silicon, ibintu byingenzi byapimwe ni amplitude magnetic induction ubukana Bm munsi yimbaraga zisanzwe za magnetique (nka B5, B10, B20, B50, B100) kimwe na magnetique ntarengwa ya μm nimbaraga zagahato Hc. Kubijyanye na Permalloy na amorphous, bapima intangiriro ya magnetiki ya μi, magnetique ntarengwa ya μm, Bs na Br; Mugiheferrite yoroshyeibikoresho barapima kandi μi, μm, Bs na Br nibindi Biragaragara ko niba tugerageje gupima ibi bipimo mubihe byafunzwe-byumuzunguruko dushobora kugenzura uburyo dukoresha ibyo bikoresho (ibikoresho bimwe bipimishwa nuburyo bwo gufungura inzira). Uburyo bukunze kuboneka harimo:
(A) Uburyo bw'ingaruka:
Ku byuma bya silikoni, hakoreshwa impeta ya kwaduka ya Epstein, inkoni zicyuma, ibikoresho bya magneti bidakomeye hamwe nuduce twa amorphous birashobora kugeragezwa na solenoide, kandi izindi ngero zishobora gutunganyirizwa mu mpeta za rukuruzi zifunze zishobora kugeragezwa. Ingero zipimisha zirasabwa kuba demagnetisme kuri leta idafite aho ibogamiye. Amashanyarazi ya DC yagabanijwe hamwe n'ingaruka za galvanometero zikoreshwa mukwandika buri kizamini. Kubara no gushushanya Bi na Hi kurupapuro rwihuza, ibipimo bya magnetiki bihuye byabonetse. Yakoreshejwe cyane mbere ya za 90. Ibikoresho byakozwe ni: CC1, CC2 na CC4. Ubu bwoko bwibikoresho bufite uburyo bwa kera bwo kugerageza, butajegajega kandi bwizewe, igiciro cyibikoresho bihendutse, kandi kubungabunga byoroshye. Ibibi ni: ibisabwa kubipimisha ni hejuru cyane, umurimo wo gupima ingingo-ku-ngingo uraruhije cyane, umuvuduko uratinda, kandi ikosa ritari ako kanya amakosa ya pulses biragoye gutsinda.
(B) Uburyo bwa metero yo guhatira:
Nuburyo bwo gupima bwabugenewe kubwinkoni nziza yicyuma, gipima gusa ibipimo bya Hcj byibikoresho. Umujyi wikizamini ubanza kuzuza icyitegererezo hanyuma ugahindura umurima wa magneti. Munsi yumurima wa magneti, coil coil cyangwa sample ikurwa kure ya solenoid. Niba ingaruka zo hanze za galvanometero muriki gihe zidafite gutandukana, guhuza imbaraga za magnetiki zihuye ni Hcj yicyitegererezo. Ubu buryo bwo gupima bushobora gupima Hcj yibikoresho neza cyane, hamwe nishoramari ryibikoresho bito, bifatika, kandi nta bisabwa kumiterere yibikoresho.
(C) Uburyo bwa DC hysteresis loop ibikoresho:
Ihame ryikizamini ni kimwe nihame ryo gupima ibintu bya hysterezezi yibikoresho bya magneti bihoraho. Ahanini, hagomba gushyirwaho ingufu nyinshi muri integer, ishobora gukoresha uburyo butandukanye nka fotoelectric amplification mutuelle inductor ihuza, kurwanya-capacitance guhuza, guhuza Vf no guhuza ibikoresho bya elegitoroniki. Ibikoresho byo mu rugo birimo: CL1, CL6-1, CL13 kuva mu ruganda rwa Sibiao rwa Sibiao; ibikoresho byo mumahanga birimo Yokogawa 3257, LDJ AMH401, nibindi. Ugereranije, urwego rwabanyamahanga bahuza urwego rwo hejuru kurenza urw'imbere mu gihugu, kandi kugenzura ukuri kwa B-kwihuta nabyo ni hejuru cyane. Ubu buryo bufite umuvuduko wihuse, ibisubizo byihuse kandi byoroshye gukoresha. Ikibi nuko amakuru yikizamini ya μi na μm atariyo, muri rusange arenga 20%.
(D) Uburyo bwo kwigana uburyo bwo kwigana:
Nuburyo bwiza bwo kugerageza uburyo bworoshye bwo kugerageza ibintu biranga magnetiki DC biranga. Nubusanzwe ni uburyo bwo kwigana mudasobwa uburyo bwo gukora ibihimbano. Ubu buryo bwateguwe ku bufatanye n’ishuri ry’Ubushinwa rya Metrology na Loudi Institute of Electronics mu 1990. Ibicuruzwa birimo: ibikoresho byo gupima ibikoresho bya MATS-2000 (byahagaritswe), ibikoresho byo gupima ibikoresho bya NIM-2000D (Ikigo cya Metrology) na TYU-2000D byoroshye DC igikoresho cyo gupima cyikora (Tianyu Electronics). Ubu buryo bwo gupima bwirinda kwambukiranya uruziga ku muzunguruko wo gupima, guhagarika neza gutembera kwa integer zeru, kandi ifite n'umurimo wo gusuzuma.
Uburyo bwo gupima ibintu AC biranga ibikoresho byoroshye bya magneti
Uburyo bwo gupima imirongo ya AC hystereze harimo uburyo bwa oscilloscope, uburyo bwa ferromagnetometero, uburyo bwo gutoranya, uburyo bwo kubika imiyoboro yigihe gito hamwe nuburyo bugenzurwa na mudasobwa ya AC igenzurwa na mudasobwa. Kugeza ubu, uburyo bwo gupima imirongo ya AC hystereze mu Bushinwa ahanini ni: uburyo bwa oscilloscope hamwe na mudasobwa igenzurwa na mudasobwa ya AC magnetisiyonike. Ibigo bikoresha uburyo bwa oscilloscope birimo: Dajie Ande, Yanqin Nano na Zhuhai Gerun; ibigo bikoresha mudasobwa igenzurwa na AC magnetisiyonike iranga uburyo bwikizamini harimo: Ubushinwa Institute of Metrology na Tianyu Electronics.
(A) Uburyo bwa Oscilloscope:
Inshuro yikizamini ni 20Hz-1MHz, inshuro ikora ni nini, ibikoresho biroroshye kandi imikorere iroroshye. Ariko, ikizamini cyukuri ni gito. Uburyo bwo kwipimisha nugukoresha résistoriste idahwitse kugirango utange icyerekezo cyibanze hanyuma uyihuze numuyoboro X wa oscilloscope, kandi umuyoboro wa Y uhujwe nikimenyetso cya kabiri cya voltage nyuma yo kwishyira hamwe kwa RC cyangwa Miller. Umurongo wa BH urashobora kugaragara biturutse kuri oscilloscope. Ubu buryo bukwiranye no kugereranya kugereranya ibintu bimwe, kandi umuvuduko wikizamini urihuta, ariko ntushobora gupima neza ibipimo bya magnetiki biranga ibintu. Mubyongeyeho, kubera ko intangarugero ihoraho hamwe no kwiyuzuzamo magnetiki induction idafunze-loop igenzurwa, ibipimo bihuye kumurongo wa BH ntibishobora kwerekana amakuru nyayo yibikoresho kandi birashobora gukoreshwa mukugereranya.
(B) Uburyo bwa ferromagnetic ibikoresho:
Uburyo bwa ferromagnetic nuburyo bwitwa metero ya vector, nkibikoresho byo gupima ubwoko bwa CL2. Inshuro yo gupima ni 45Hz-1000Hz. Ibikoresho bifite imiterere yoroshye kandi biroroshye gukora, ariko irashobora kwandika gusa ibizamini bisanzwe. Igishushanyo mbonera gikoresha icyiciro-cyunvikana cyo gukosora kugirango bapime agaciro ako kanya ya voltage cyangwa amashanyarazi, kimwe nicyiciro cyibiri, kandi ikoresha icyuma gifata amajwi kugirango yerekane umurongo wa BH wibikoresho. Bt = U2au / 4f * N2 * S, Ht = Umax / l * f * M, aho M ni inductance ya mutuelle.
(C) Uburyo bwo gutoranya:
Uburyo bw'icyitegererezo bukoresha icyitegererezo cyo guhindura ibintu kugirango uhindure umuvuduko mwinshi wihuta wa voltage mubimenyetso bya voltage hamwe na flake imwe ariko bihinduka gahoro gahoro, kandi ikoresha AD yihuta cyane kugirango itangwe. Ikizamini cyamakuru nukuri, ariko inshuro yikizamini igera kuri 20kHz, bikaba bigoye guhuza nogupima inshuro nyinshi gupima ibikoresho bya magneti.
(D) Uburyo bwo gupima AC magnetisiyonike:
Ubu buryo nuburyo bwo gupima bwateguwe mugukoresha byuzuye ubushobozi bwo kugenzura no gutunganya software ya mudasobwa, kandi nicyerekezo cyingenzi mugutezimbere ibicuruzwa. Igishushanyo gikoresha mudasobwa hamwe nicyitegererezo cyo gufunga-kugenzura, kugirango ibipimo byose bikorwe uko bishakiye. Ibipimo byo gupima bimaze kwinjizwa, inzira yo gupima irahita irangira kandi igenzura rishobora kwikora. Imikorere yo gupima nayo irakomeye cyane, kandi irashobora kugera kubipimo nyabyo byibipimo byose byibikoresho byoroshye bya magneti.
