Yuav ua li cas teeb meem thaum lub cov khoom siv ntau zaus nrhiav kev txhaum?

1. Qhov tshwm sim txhaum cai Cov cuab yeej siv hluav taws xob ntau zaus ua haujlwm ib txwm ua, tab sis lub suab nrov nrov nrov tuaj yeem hnov ​​​​ib lub sijhawm, thiab DC voltmeter me ntsis oscillates. Siv lub oscilloscope los soj ntsuam qhov voltage waveform ntawm ob qho kawg ntawm inverter choj. Nws tuaj yeem pom tias lub sijhawm ntawm lub inverter luv luv, ib lub voj voog tsis ua haujlwm lossis lub sijhawm luv luv ntawm lub sijhawm tsis txaus ntseeg tsis ua haujlwm, thiab lub sijhawm sib txuas ntawm lub inverter Circuit Court tsis ua haujlwm rau lub sijhawm luv luv, tab sis lub sijhawm rov qab los ntawm tus kheej yog luv, thiab qhov tsis ua haujlwm yog. feem ntau ntawm inverter tswj. Ib feem ntawm nws yog cuam tshuam los ntawm lub rectifier mem tes, thiab aperiodic luv luv-term tsis ua hauj lwm yog feem ntau tshwm sim los ntawm cov tsis zoo rwb thaiv tsev ntawm lub lem ntawm intermediate zaus transformer.

2. Qhov tshwm sim txhaum cai Tom qab cov khoom siv hluav taws xob quenching tau ua haujlwm ib txwm ua rau lub sijhawm, cov cuab yeej muaj suab txawv txav, thiab ntsuas ntsuas ntsuas ntsuas thiab cov khoom siv tsis ruaj khov. Cov suab nrov txawv txav tshwm sim tom qab cov khoom siv tau ua haujlwm rau lub sijhawm. Kev ua haujlwm tsis ruaj khov, feem ntau vim tias cov yam ntxwv thermal ntawm cov khoom siv hluav taws xob tsis zoo. Cov khoom siv hluav taws xob tuaj yeem muab faib ua ob ntu: tsis muaj zog tam sim no thiab muaj zog tam sim no, thiab qhov chaw tswj tau raug cais tawm los tiv thaiv kev puas tsuaj. Thaum lub tshuab hluav taws xob tseem ceeb tsis txuas nrog lub tshuab hluav taws xob tseem ceeb, tsuas yog lub zog hluav taws xob ntawm qhov chaw tswj tau qhib. Tom qab tswj kav ua haujlwm rau ib lub sijhawm, siv ib lub sijhawm oscilloscope los xyuas cov mem tes tswj kom pom seb cov mem tes yog qhov qub.

Nyob rau ntawm qhov chaw ntawm kev lees paub tias tsis muaj teeb meem hauv kev tswj hwm, qhib cov khoom siv, thiab tom qab qhov tshwm sim txawv txav tshwm sim, ua tib zoo saib xyuas qhov voltage nco waveform ntawm txhua lub thyristor nrog ib qho oscilloscope, thiab nrhiav cov thyristor nrog cov yam ntxwv tsis zoo thermal; Yog hais tias qhov voltage nco waveform ntawm lub thyristor yog tag nrho cov zoo li qub. Nyob rau lub sijhawm no, peb yuav tsum tau saib xyuas seb puas muaj teeb meem nrog lwm cov khoom siv hluav taws xob, thiab xyuam xim tshwj xeeb rau Circuit Court breakers, capacitors, reactors, tooj liab bar hu thiab lub ntsiab transformers.
