Ukuthumela ubuchwepheshe be imishini yokufudumeza ephezulu kakhulu

Ukuthunyelwa imishini yokufudumeza ephezulu kakhulu

Okujwayelekile kufanele kube okujwayelekile ngaphambi kokusetshenziswa.Hlola inverter ngokulandela lezi zinyathelo ezilandelayo:

Close kuphela vala ukunikezwa kwengxenye yokulawula (inothi: ungavali inkinobho enkulu yomoya yesifunda esikhulu), cindezela umnyango wekhabethe

Inkinobho yokuqalisa ephambene (inkinobho eluhlaza), lungisa i-knob yokulungisa amandla ngokwewashi ukuya endaweni ephezulu, bese ubheka nge-oscilloscope enemigqa emibili ukuthi isignali yedrayivu esigxotsheni sokulawula semodyuli ngayinye ye-IGBT ijwayelekile (ishayela cishe lingama-50% igagasi lesikwele, ishayela ububanzi

Okuphezulu kungo + 15V, ikhefu lingaba ngu-8V. Imigqa ekhuphukayo nokwehla ingaphakathi kwe-1 μS, nengalo yebhuloho ibheke phezulu naphezulu

Isifunda esifile samapulisi esango le-IGBT sikhulu kune-2 Μs) futhi siqinisekisa ukuthi isignali yokushayela ye-IGBT yengalo efanayo yebhuloho i-isophase (amaphutha aphezulu nangaphansi akumele adlule u-0.5 Μs) kanye nesiginali ye-IGBT yedrayivu ephezulu nangaphansi izingalo zebhuloho kumele ziguqulwe.

Ukuhlolwa kwe-② rectification pulse.Cindezela inkinobho yokuqala, amasango amathathu we-SCR kufanele abe nokushaya kwenhliziyo nge-amplitude enkulu kune-1.8V, ububanzi be-pulse kanye nobuningi be-pulse obungaba ngu-10kHz.

Test ukuhlolwa kwengcindezi ukumelana.Close the main circuit large air switch (musa ukuvala isilawuli voltage switch) Ngalesi sikhathi, bona i-DC voltmeter pointer is slowly rising to more than 500V, bheka ukuthi imishini kuyinto evamile (akukho umsindo okungavamile, akukho phunga, futhi akukho ukuwohloka kwedivayisi), gcina ngakwesokudla imizuzu eyi-10, kuya ngemishini ejwayelekile, inkinobho enkulu yamandla ingacinywa.Ngamanje i-DC

Ingcindezi yehlela kancane ku-zero.

Equipment imishini yokufudumeza efrikhwensi ephezulu, landela lezi zinyathelo ezilandelayo ukuqala i-inverter.

Xhuma amanzi okupholisa futhi uhlole ukuthi ngabe isiteshi ngasinye samanzi okupholisa sijwayelekile yini.Lungisa i-counterclockwise ye-knob yokulungisa amandla endaweni encane, vala iswishi yepompo, iswishi yamandla wokulawula kanye neswishi yamandla amakhulu, Qaphela lapho i-voltmeter ye-DC inyukela cishe ku-500V nge ukushaja Cindezela inkinobho yokuqala ukubambezela imizuzwana emi-2 ku-inverter elungile Ithebula ngalinye lizoba nemiyalo ehambisanayo, kancane kancane lenyuse i-knob yokulungisa amandla ngokwewashi, futhi imiyalo ye-DC yamanje kanye nemitha yamandla izokwanda ngokushesha futhi ifinyelele kunani elinikeziwe. manje isebenza ngokujwayelekile.Abasebenzi abathunyelwe ngumenzi wemishini ukulungisa inani ngalinye lokubeka ukuvikela kunani elidingekayo (okokusebenza kulungiswe ngokuyisisekelo ngaphambi kokushiya ifektri, futhi kungalungiswa ngokufanele ngokwesayithi).

Incazelo ye-enti motherboard potentiometer

I-P1—— ishuna ingwegwe yesikhathi samanje ephakathi nendawo eseduze ne-sine wave bese ishiya ama-engeli angaba ngu-200.

I-P2—— ilungisa ubungako bamanani wamanje wokunciphisa ubungako bamaphakathi.

I-P3— FM yamanje inciphisa usayizi wenani.

I-P8—— ilungisa usayizi wenani lokuvikelwa kwamanje wamaphakathi wamaphakathi.

I-P9—— Usayizi wenani lokuvikelwa kwamanje le-FM.

P10—— Ukulinganiswa Kwethebula Lemvamisa.

⑥ Shunown kulezi zinyathelo ezilandelayo.

Okokuqala lungisa i-knob yokulungisa amandla ophikisana newashi uye endaweni encane, cindezela inkinobho yokumisa emuva, bese umisa umsindo wamaza amaphakathi ngokushesha.Cisha inkinobho enkulu yamandla, bheka ukwehla kwemitha yamandla kagesi we-DC uye ku-zero, bese ucisha iswishi yokuhambisa ugesi nepompo lamanzi

Shintsha.

Incazelo yesibani sesibonisi sesinali lesilawuli esikhulu se-⑦ imishini yokufudumeza ephezulu kakhulu:

Incazelo yesibani sesibonisi sephaneli yokuvikela yangaphandle:

⑨ Isexwayiso: Ngemuva kokuthi inkinobho enkulu yamandla ivaliwe noma iguquliwe, akuvunyelwe ukuhlola noma iyiphi ingxenye nge-oscilloscope noma itafula, ngaphandle kwalokho ukwehluleka kuzokwenzeka ngenxa yokufinyelela kwemingcele engaphandle kokuphela kokuhlolwa kwensimbi.
