Qhov no yog qhov tsim nyog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws yog qhov tsim nyog yuav tsum tau ua kom nce lossis txo qhov kev txwv ntau zaus hauv qhov system. Hauv lwm cov qauv ntawm thyristors, tej zaum yuav muaj ob peb. Lawv tau nruab nrog ib leeg siv cathodes. Yog li ntawd, qhov ua tau zoo ntawm cov cuab yeej tuaj yeem txhim kho tau zoo.
cov khoom siv tsawg zaus
Rau cov khoom siv uas muaj zaus tsawg dua 30 Hz, muaj xws li qhov ntsuas hluav taws xob 220V. Nws Circuit Court yog zoo ib yam li cov circuits ntawm relay qauv, tshwj tsis yog cov transistors. Hauv qhov no, lawv muaj nyob nrog tus emitter. Qee lub sij hawm tus tswj tshwj xeeb raug teeb tsa ntxiv. Muaj ntau nyob ntawm cov chaw tsim khoom thiab cov qauv. Tus maub los hauv lub stabilizer yuav tsum tau xa cov teeb liab mus rau chav tswj.
Yuav kom kev sib txuas ua tau zoo, cov neeg tsim khoom siv lub amplifier. Nws feem ntau yog ntsia ntawm qhov nkag. Feem ntau muaj winding ntawm cov zis nyob rau hauv lub system. Yog hais tias peb tham txog qhov voltage txwv ntawm 220 V, muaj ob lub capacitor. Tam sim no hloov coefficient ntawm cov khoom siv no yog qhov tsawg heev. Yog vim li cas rau qhov no yog suav hais tias yog ib qho kev txwv tsawg zaus, uas yog qhov tshwm sim ntawm kev ua haujlwm ntawm tus maub los. Txawm li cas los xij, qhov tseem ceeb saturation yog qhov siabcim. Qhov no feem ntau yog vim cov transistors uas tau nruab nrog cov emitters.
Vim li cas peb thiaj xav tau cov qauv ferroresonant?
Ferroresonant voltage stabilizers (daim duab qhia hauv qab) yog siv nyob rau hauv ntau qhov chaw tsim khoom. Lawv qhov pib ntawm rhiab heev yog qhov siab heev vim muaj cov khoom siv hluav taws xob muaj zog. Transistors feem ntau yog ntsia ua khub. Tus naj npawb ntawm cov capacitors nyob ntawm tus neeg tsim khoom. Hauv qhov no, qhov no yuav cuam tshuam rau qhov kawg rhiab heev pib. Thyristors tsis siv los tswj qhov voltage.
Nyob hauv qhov xwm txheej no, tus neeg sau tuaj yeem tiv tau txoj haujlwm no. Lawv qhov kev nce qib siab heev vim qhov kev xa tawm ncaj qha. Yog tias peb tham txog cov yam ntxwv tam sim no-voltage, ces qhov kev tiv thaiv hauv Circuit Court yog tswj ntawm 5 MPa. Nyob rau hauv rooj plaub no, qhov no muaj txiaj ntsig zoo ntawm kev txwv qhov zaus ntawm stabilizer. Ntawm cov zis, qhov sib txawv kuj tsis tshaj 3 MPa. Transistors txuag los ntawm kev nce voltage hauv qhov system. Yog li, overcurrent tuaj yeem zam feem ntau.
Tom qab Hom Stabilizers
Lub tswv yim ntawm cov khoom stabilizers tom qab yog tus cwj pwm los ntawm kev ua haujlwm tau zoo. Lub input voltage nyob rau hauv cov ntaub ntawv no yog nyob rau nruab nrab 4 MPa. Nyob rau hauv cov ntaub ntawv no, lub pulsation yog tswj nrog ib tug loj amplitude. Nyob rau hauv lem, cov zis voltage ntawm lub stabilizer yog 4 MPa. Resistors nyob rau hauv ntau tus qauv yog ntsia rau hauv "MP" series.
Tam sim no hauv Circuit Court yog tswj hwm tas lithiab vim qhov no, qhov txwv zaus tuaj yeem txo qis rau 40 Hz. Dividers hauv amplifiers ntawm hom no ua haujlwm ua ke nrog cov resistors. Yog li ntawd, tag nrho cov nodes functional yog interconnected. DC amplifier feem ntau yog ntsia tom qab lub capacitor ua ntej winding.
