Siv multimeter los xyuas seb lub lim puas zoo lossis phem
Yog hais tias muaj ib tug sab hauv Circuit Court tawg nyob rau hauv lub lim, lub inverter yuav tsum tsis txhob ua hauj lwm, vim hais tias cov lim feem ntau yog txuas nrog nyob rau hauv series mus rau lub hwj chim mov ntawm lub inverter.
Yog tias lub lim tsis ua haujlwm, nws yuav ua rau muaj kev cuam tshuam rau cov khoom siv nyob ib ncig ntawm lub inverter, uas yuav ua rau lub elevator ua haujlwm tsis zoo, lossis cov khoom siv nyob ib puag ncig nws tsis ua haujlwm zoo, ua rau muaj suab nrov, kev txav txav tsis zoo, thiab lwm yam. Nyob rau hauv cov xwm txheej hnyav, yuav ua rau kev puas tsuaj rau cov khoom siv hluav taws xob tsis zoo no
Qhov txawv ntawm active filters thiab passive filters:
1. Cov lim dej ua haujlwm yog hluav taws xob, thaum cov lim dej tsis zoo yog cov neeg kho tshuab;
2. Cov lim dej nquag pom muaj qee yam kev sib haum xeeb thiab tom qab ntawd tso tseg. Cov lim dej passive tsim ib qho kev sib haum xeeb channel los ntawm kev koom tes ntawm lub reactor thiab lub capacitor kom nqus cov harmonics;
3. Siv cov lim dej tsis zoo vim muaj cov capacitors.
Rau lub ntsej muag acoustic lim, nws ob lub tswv yim pins 1 thiab 2, nws ob qhov tso zis pins 3 thiab 4, thiab cov tswv yim thiab cov zis pins yog insulated (raws li qhia hauv daim duab), thiab lawv txhua tus yog insulated los ntawm shielding pin 5. , thaum ntsuas qhov tsis kam ntawm ob siv R × 1 k Ω ntau ntawm ib lub multimeter, nws yuav tsum yog ∞. Yog tias muaj qhov tsis kam ntawm ntau pua lossis ntau txhiab ohms, nws qhia tau hais tias qhov kev ua haujlwm ntawm lub ntsej muag acoustic lim tau deteriorated. Yog tias qhov kev tiv thaiv me me heev, nws qhia tau tias cov lim dej acoustic tau tawg lawm.
