Nzira yekuona sei musimboti we-high-frequency transformer? Vanhu vanotenga musimboti we-high-frequency transformer vanotya kutenga musimboti wakagadzirwa nezvinhu zvakaderera. Saka iyo core inofanira kuonekwa sei? Izvi zvinoda kunzwisisa dzimwe nzira dzekuona dzepakati pe ahigh-frequency transformer.
Kana iwe uchida kuona iyo yakakosha ye-high-frequency transformer, iwe zvakare unofanirwa kuziva kuti ndezvipi zvinhu zvinowanzoshandiswa kune yakakosha. Kana uchifarira, unogona kuzvitarisa. Kune akawanda marudzi akasiyana enyoro maginetizvinhu zvinoshandiswa kuyera magnetic properties. Nekuti iwo anoshandiswa nenzira dzakasiyana, kune akawanda akaomarara paramita anoda kuyerwa. Kune akawanda akasiyana zviyero uye nzira dzeimwe neimwe parameter, inova ndiyo inonyanya kukosha chikamu chekuyera magineti maitiro.
Kuyera kweDC magineti zvivakwa
Yakasiyana yakapfava magineti zvinhu zvine akasiyana ekuyedza zvinodiwa zvichienderana nechinhu. Kune yemagetsi yakachena simbi nesilicon simbi, zvinhu zvikuru zvakayerwa ndeye amplitude magineti induction intensity Bm pasi peyakajairwa magineti simba (seB5, B10, B20, B50, B100) pamwe nehupamhi hwemagineti permeability μm uye kumanikidza simba Hc. Kune Permalloy uye amorphous match, vanoyera yekutanga magineti permeability μi, yakakura magineti permeability μm, Bs uye Br; apo fornyoro ferritezvinhu ivo vanoyerawo μi , μm , Bs uye Br etc. Zviri pachena kuti kana tikaedza kuyera maparamendi aya pasi pemamiriro evhavha-yedunhu tinogona kudzora mashandisiro atinoita zvinhu izvi (zvimwe zvinhu zvinoedzwa neyakavhurika-circuit nzira). Nzira dzinonyanyozivikanwa dzinosanganisira:
(A) Impact nzira:
Kune silicon simbi, Epstein sikweya mhete dzinoshandiswa, yakachena simbi tsvimbo, isina simba remagineti uye amorphous mitsetse inogona kuedzwa ne solenoids, uye mamwe masampuli anogona kugadziriswa kuita akavharwa-yedunhu magineti mhete anogona kuongororwa. Iwo masampula ebvunzo anodiwa kuti anyatso demagnetized kune isina kwayakarerekera. A commutated DC magetsi emagetsi uye inokonzeresa galvanometer inoshandiswa kurekodha yega yega test point. Nekuverenga nekudhirowa Bi uye Hi papepa rekubatanidza, iwo anowirirana magineti epfuma paramita anowanikwa. Yakashandiswa zvakanyanya pamberi pema1990. Zviridzwa zvinogadzirwa ndezvi: CC1, CC2 uye CC4. Rudzi urwu rwechiridzwa chine yekirasi yekuyedza nzira, yakagadzikana uye yakavimbika bvunzo, yakachipa chiridzwa mutengo, uye nyore kugadzirisa. Izvo zvisingabatsiri ndezvi: zvinodiwa kune vanoedza zvakanyanya, basa rekuongorora-ne-point rakaoma kwazvo, kumhanya kunononoka, uye kusiri-pakarepo kukanganisa kwepulses kwakaoma kukunda.
(B) Coercivity mita nzira:
Iyo inzira yekuyeresa yakanyatsogadzirirwa kune yakachena simbi tsvimbo, iyo inongoyera iyo Hcj parameter yechinhu. Guta rekuyedza rinotanga razadza sampuli rozodzosera kumashure magineti. Pasi peimwe magineti, coil yakakandwa kana sampuli inodhonzwa kubva kune solenoid. Kana iyo yekunze kukanganisa galvanometer panguva ino isina kutsauka, inoenderana reverse magineti ndiyo Hcj yemuenzaniso. Iyi nzira yekuyera inogona kuyera Hcj yezvinhu zvakanaka kwazvo, nekudyara kwemidziyo midiki, inoshanda, uye hapana zvinodiwa pachimiro chechinhu.
(C) DC hysteresis loop chiridzwa nzira:
Nheyo yekuyedza yakafanana neyeyero musimboti weiyo hysteresis loop yekusingaperi magineti zvinhu. Kunyanya, kuedza kukuru kunoda kuitwa mukubatanidza, iyo inogona kutora mafomu akasiyana-siyana akadai se photoelectric amplification mutual inductor integration, resistance-capacitance integration, Vf conversion integration uye electronic sampling integration. Midziyo yemumba inosanganisira: CL1, CL6-1, CL13 kubva kuShanghai Sibiao Factory; midziyo yekune dzimwe nyika inosanganisira Yokogawa 3257, LDJ AMH401, etc. Zvichienderana, chiyero chevasanganisi vekune dzimwe nyika chakakwirira zvikuru kupfuura chemumba, uye kutonga kwakarurama kweB-speed mhinduro zvakare yakakwirira kwazvo. Iyi nzira ine kukurumidza kuyedza kumhanya, intuitive mhedzisiro uye iri nyore kushandisa. Izvo zvakashata ndezvekuti bvunzo data ye μi uye μm haina kururama, kazhinji inodarika 20%.
(D) Simulation kukanganisa nzira:
Parizvino ndiyo yakanakisa nzira yekuyedza yekuyedza yakapfava magineti DC maitiro. Iyo inonyanya kuenzanisa nzira yekombuta yeiyo artificial impact nzira. Iyi nzira yakagadzirwa pamwe chete neChinese Academy yeMetrology uye Loudi Institute of Electronics muna 1990. Zvigadzirwa zvinosanganisira: MATS-2000 magnetic material measuring device (yakamiswa), NIM-2000D magnetic material measuring device (Metrology Institute) uye TYU-2000D yakapfava magineti. DC otomatiki yekuyera chiridzwa (Tianyu Electronics). Iyi nzira yekuyera inodzivirira kupindira-kukanganisa kwedunhu kune kuyerwa dunhu, zvinonyatso kudzvanya kudonha kweiyo integrator zero point, uye zvakare ine scanning test function.
Kuyera nzira dze AC maitiro ezvakapfava magineti zvinhu
Nzira dzekuyera AC hysteresis loops dzinosanganisira oscilloscope nzira, ferromagnetometer nzira, sampling nzira, yenguva pfupi waveform yekuchengetedza nzira uye inodzorwa nekombuta AC magineti maitiro ekuyedza nzira. Parizvino, nzira dzekuyera AC hysteresis loops muChina dzinonyanya: oscilloscope nzira uye komputa-inodzorwa AC magineti maitiro ebvunzo maitiro. Makambani anoshandisa nzira ye oscilloscope anonyanya kusanganisira: Dajie Ande, Yanqin Nano uye Zhuhai Gerun; iwo makambani anoshandisa komputa-inodzorwa AC magineti maitiro ekuedza maitiro anonyanya kusanganisira: China Institute of Metrology uye Tianyu Electronics.
(A) Oscilloscope nzira:
Iyo bvunzo frequency ndeye 20Hz-1MHz, iyo frequency yekushandisa yakafara, michina iri nyore uye kushanda kuri nyore. Zvisinei, chokwadi chekuedza chakaderera. Iyo nzira yekuyedza ndeye kushandisa isiri-inductive resistor kuenzanisa yekutanga ikozvino uye kuibatanidza kune X chiteshi cheoscilloscope, uye Y chiteshi chakabatana kune yechipiri voltage siginecha mushure meRC kubatanidzwa kana Miller kubatanidzwa. Iyo BH curve inogona kutariswa zvakananga kubva kune oscilloscope. Iyi nzira inokodzera kuyerwa kuyerwa kwechinhu chimwe chete, uye bvunzo yekumhanyisa inokurumidza, asi haigone kuyera nemagineti maitiro eiyo zvinhu. Mukuwedzera, sezvo iyo yakakosha nguva dzose uye saturation magnetic induction haisi yakavharwa-loop inodzorwa, iyo inofananidzwa parameters paBH curve haigoni kumiririra chaiyo data yezvinyorwa uye inogona kushandiswa kuenzanisa.
(B) Ferromagnetic chiridzwa nzira:
Iyo ferromagnetic chiridzwa nzira inonzi zvakare vector mita nzira, senge yepamba CL2 mhando yekuyeresa chiridzwa. Iyo yekuyera frequency ndeye 45Hz-1000Hz. Midziyo yacho ine chimiro chakareruka uye iri nyore kushandisa, asi inogona kungorekodha zvakajairika test curves. Iyo dhizaini dhizaini inoshandisa chikamu-sensitive rectification kuyera kukosha kwekukurumidza kwevoltage kana yazvino, pamwe nechikamu chezviviri, uye inoshandisa rekodhi kuratidza iyo BH curve yezvinhu. Bt=U2au/4f*N2*S, Ht=Umax/l*f*M, uko M ndiko kupindirana.
(C) Sampling nzira:
Iyo sampling nzira inoshandisa sampling shanduko yedunhu kushandura yakakwira-speed yekuchinja voltage sigiyori kuita chiratidzo chevoltage ine yakafanana waveform asi inononoka kushandura kumhanya, uye inoshandisa yakaderera-speed AD yesampling. Iyo data yekuyedza ndeyechokwadi, asi iyo frequency yekuyedza inosvika 20kHz, iyo yakaoma kuchinjika kune yakakwirira-frequency kuyerwa kwezvinhu zvemagineti.
(D) AC magnetization maitiro ekuedza nzira:
Iyi nzira inzira yekuyera yakagadzirirwa nekushandisa zvizere kutonga uye software yekugadzirisa kugona kwemakomputa, uye zvakare igwara rakakosha rekuvandudza chigadzirwa. Iyo dhizaini inoshandisa makomputa uye sampling loops yekuvhara-loop control, kuitira kuti kuyerwa kwese kuitwe pakuda. Kana mamiriro ekuyera apinzwa, kuyerwa kwemaitiro kunopedzwa otomatiki uye kutonga kunogona kuve otomatiki. Iyo yekuyera basa zvakare ine simba kwazvo, uye inokwanisa kuzadzisa kuyerwa kwakaringana kweese ma paramita ezvakapfava magineti zvinhu.
Chinyorwa chinotumirwa kubva paInternet. Chinangwa chekuendesa mberi ndechekugonesa munhu wese kutaura zvirinani uye kudzidza.
