Dab tsi yuav tshwm sim thaum cov hartonic dedortion ncav nws lub ncov?
Sep 19, 2025| Nyob rau hauv lub zog hluav taws xob zoo tshaj plaws, qhov voltage thiab tam sim no yuav tsum muaj zoo meej thiab du sine vuag. Txawm li cas los xij, nyob rau hauv lub hwj chim tiag tiag daim phiaj, nws tau sau nrog ntau cov nonfiniers loads, thiab lwm yam uas yog cov suab nrov uas muaj cov suab nrov sib npaug
Tag nrho cov harmonic distortion (THD) yog qhov ntsuas tau siv los ntsuas cov℃ntawm waveform distortion. Thaum tus nqi thim dheev nce rau nws lub ncov, nws tsis yog ib qho yooj yim hloov; Nws qhia tau tias tag nrho cov zog hluav taws xob tau ntsib ib qho - cua daj cua dub ", nrog rau kev cuam tshuam loj thiab ntau- Faceted.
1. Cov kev cuam tshuam ncaj qha rau cov khoom siv fais fab thiab kab
Transformer thiab cable: Harmonic cov dej khov kho thiab cov nyhuv tseem ceeb, ua rau muaj kev pom zoo ntau yam, ua rau muaj kev tiv thaiv zoo. Nyob rau tib lub sijhawm, siab - zaus mirmonics yuav ua rau cov hlau tsis ntxiv hauv cov tub ntxhais. Qhov nce ntawm kev tiv taus thiab nce nyob rau hauv kev poob ua ke ua rau ib tug ntse nce nyob rau hauv kub ntawm lub transformer thiab cable. Hauv cov mob me me, qhov no yuav nrawm rwb thaiv tsev laus thiab luv luv lub neej; Thaum muaj mob hnyav, tej zaum nws yuav ua rau rwb thaiv tsev tawg thiab hluav taws. Lub transformer kev ua haujlwm feem ntau nyob rau hauv tag nrho cov kev thauj khoom ntawm lub zog zaus tej zaum twb muaj nyob rau hauv lub xeev harmedly nyob rau hauv ib puag ncig harmonic.
(2) tig machine (cov tshuab hluav taws xob / lub tshuab hluav taws xob / lub zog) Rau cov tshuab hluav taws xob, lub zog harmonic yuav ua rau cov cua sov ntxiv kom tsim tawm hauv lub rotor, uas tuaj yeem tshaj lub peev xwm ntawm lawv lub tshuab taws txias, ua rau rotor kev puas tsuaj.
Sacreat thiab reactive fais fab nyiaj: qhov no yog thaj chaw feem ntau nquag ua teeb meem rau kev sib txawv. Capacitors muaj immession tsis tshua muaj neeg siab tawv rau high- zaus muaj kev sib haum xeeb, uas tuaj yeem ua rau muaj kev sib tw loj heev. Dab tsi yog qhov txaus ntshai tshaj plaws yog tias lawv tuaj yeem tsim cov kev hloov kho parallel nrog cov txheej txheem kev ua haujlwm, lub zog ntawm cov Harmonic tam sim no los ntawm ob peb zaug lossis txawm tias ntau zaus. Qhov no tuaj yeem yooj yim ua rau lub peev hluav taws xob fuse kom tshuab, lub caport mus rau kom muaj kev them nyiaj lossis tawg, ua rau cov tshuaj tiv thaiv hluav taws xob tsis muaj peev xwm ua haujlwm kom raug.
