Khoom feature thiab daim ntawv thov

1. Lub peev xwm ntawm lub zog yuav tsum tau txo qis. Cov khoom siv hluav taws xob resonant tsim cov khoom siv hluav taws xob siab thiab cov tam sim no loj los ntawm kev sib hloov ntawm cov resonant reactor thiab lub peev xwm ntawm cov qauv kuaj. Nyob rau hauv tag nrho cov system, lub hwj chim mov tsuas yog yuav tsum tau muab lub active zog noj feem. Yog li, lub zog xav tau rau kev sim tsuas yog 1 / Q ntawm lub peev xwm xeem.

2. Cov khoom hnyav thiab ntim tau txo qis. Cov khoom siv hluav taws xob resonant tshem tawm cov khoom loj loj - lub zog hluav taws xob tswj hluav taws xob thiab cov pa siab siab - lub zog fais fab - zaus ntsuas transformers. Ntxiv mus, lub resonant excitation fais fab mov yuav tsum tsuas yog 1/Q ntawm lub peev xwm xeem, drastic txo lub cev nyhav thiab ntim -feem ntau mus rau 1/10 mus rau 1/30 ntawm cov pa xeem cov khoom.

3. Txhim kho qhov tso zis voltage waveform. Lub resonant fais fab mov ua hauj lwm raws li ib tug resonant lim Circuit Court, zoo mitigating output voltage distortion los ua ib tug siab - zoo sinusoidal waveform. Qhov no tiv thaiv kev ua txhaum ntawm cov qauv kuaj uas tshwm sim los ntawm kev sib haum xeeb peaks.

4. Tiv thaiv kom luv luv - Circuit Court tam sim no hlawv puas ntawm cov ntsiab lus txhaum. Nyob rau hauv series resonance hom, thaum lub rwb thaiv tsev tsis muaj zog nyob rau hauv cov qauv kuaj lov, lub Circuit Court tam sim ntawd detunes, ua rau lub voj tam sim no sai txo mus rau 1 / Q ntawm qhov kev sim tam sim no. Nyob rau hauv sib piv, thaum lub sij hawm withstand voltage xeem siv parallel resonance los yog sim transformers, lub breakdown tam sim no surges los ntawm kaum tawm zaus. Muab piv rau ob, qhov luv -circuit tam sim no txawv ntawm qhov tawg tam sim no ntau pua zaus. Yog li ntawd, series resonance zoo nrhiav cov rwb thaiv tsev tsis muaj zog yam tsis muaj kev pheej hmoo ntawm luv luv -circuit tam sim no hlawv kev puas tsuaj rau qhov txhaum.

5. Tsis muaj rov qab overvoltage tshwm sim. Thaum cov qauv kuaj tau tawg, qhov poob ntawm resonance tej yam kev mob ua rau lub siab voltage ploj mus sai sai, tua lub arc tam sim ntawd. Cov txheej txheem rov qab voltage yog ncua ntev, tso cai rau lub sijhawm txaus los txiav lub hwj chim ua ntej qhov hluav taws xob flashover rov qab los. Qhov kev rov qab no yog ib qho kev sib txuas ntawm cov txheej txheem ntawm lub zog tsub zuj zuj, tus cwj pwm los ntawm nws lub sijhawm ntev thiab tsis ua tiav ntawm ib qho kev rov qab overvoltage.
