Momwe mungathetsere vuto la overvoltage la pafupipafupi AC resonant test system?

Ma frequency a AC resonant test system amagwiritsidwa ntchito kuzindikira mphamvu ya kutchinjiriza kwa zida zamagetsi.Ndikofunikira kwambiri pakuwunika ngati zida zamagetsi zitha kugwira ntchito.Ndiwonso njira yofunikira yowonetsetsa kuti chipangizocho chikuyenda bwino komanso kupewa ngozi zachitetezo.Chifukwa kachipangizo koyesa kutembenuka kwafupipafupi kwa resonance kumatha kuwonetsa bwino momwe zida zamagetsi zimagwirira ntchito pansi pa voltage ya AC, zimatha kupeza zolakwika komanso zowona.

Chifukwa resonance mfundo anatengera ndi pafupipafupi kutembenuka mndandanda resonance mayeso chipangizo, voteji wa pafupipafupi ena mu dongosolo kuzungulira ndi capacitance ndi anachita mu kuzungulira kupanga resonance.Mpweya wodutsa pa capacitor umafika pamagetsi oyesera.

Malingana ndi mfundo zomwe zili pamwambazi komanso momwe zinthu zilili poyesa malo, kuwonjezereka kwa maulendo afupipafupi kutembenuka kwamtundu wa resonance nthawi zambiri kumachitika muzochitika ziwiri, imodzi ndi pamene chida chikufufuza malo a resonance ndi njira yopangira voteji ya resonance;chinacho ndi pamene mphamvu yowonjezera ifika pamagetsi oyesera.kutengera pa.

Pankhani ya kupeza resonance mfundo mndandanda resonance ndi boosting kwa mayeso voteji, nthawi zambiri mu nkhani kuti kupirira voteji wa mankhwala mayeso ndi osayenera kapena malo chilengedwe si kunachitika kusintha kwakukulu, mayeso sangabweretse overvoltage chitetezo. kapena zolakwa zina.Komabe, popeza voteji gululi si nthawi zonse ndipo voteji athandizira wa magetsi kusinthasintha, linanena bungwe mkulu-voltage limakhalanso ndi kusakhazikika, zomwe zingachititse overvoltage chitetezo pa nsonga voteji.Ngati mphamvu voteji zimasinthasintha, mukhoza kusintha overvoltage chitetezo cha chida, ndi kuika chitetezo overvoltage kwa mtengo wapatali.Nthawi zambiri timafunikira chitetezo chowonjezera kuti chikhazikitsidwe ku 1.1-1.2 nthawi yachitetezo chamagetsi.Pakadali pano, palibe vuto kuyiyika nthawi 1.2.

Zomwe zili pamwambazi ndizovuta, koma zimakhala zovuta kuti kusinthasintha kwa magetsi kupangitse kuti kuwonjezereka kuchitike pamene chitetezo cha overvoltage chakhazikitsidwa.Nthawi zambiri, overvoltage wa pafupipafupi kutembenuka mndandanda resonance mayeso chipangizo ndi pafupipafupi kusesa siteji ya chida, ndiko, m'kati kupeza mfundo resonance.Aliyense amene wagwiritsa ntchito pafupipafupi kutembenuka mndandanda resonance mayeso chipangizo amadziwa kuti m`kati kupeza resonance mfundo ya pafupipafupi kutembenuka mndandanda resonance mayeso chipangizo, voteji ndi pafupipafupi ndi ofanana liniya ubale monga parabola.Mwachikhazikitso, dongosolo limapeza magetsi apamwamba, ndiko kuti, vertex ya parabola, monga resonance point.Popeza chiphunzitso cha resonance mfundo imatha kutulutsa mphamvu yamagetsi otsika mpaka nthawi 80 (chifukwa cha mawonekedwe abwino ndi maubwenzi ena nthawi zambiri osapitilira 30), voteji yofunikira pakusesa pafupipafupi kwa chipangizo choyesera cha pafupipafupi kutembenuka kwa resonance nthawi zambiri imakhala 20. -50V, ndipo voteji pambuyo chisangalalo zambiri ndi mazana angapo volts.Kupyolera mu mfundo pamwamba, tapeza kuti ngati mayeso voteji wa mankhwala mayeso tiyenera ndi otsika kuposa voteji pamene dongosolo resonance ndi resonance mfundo, dongosolo akhoza kukhala overvoltage chitetezo pamene basi amafufuza mfundo resonance.Pa nthawi imeneyi, lonse variable pafupipafupi mndandanda resonance mayeso chipangizo sangathe kupirira mavuto, mayeso sakanatha.

Njira yothetsera vutoli imakhalanso yovuta.Sikuti chipangizo choyezera pafupipafupi cha resonance sichingathe kupanga voteji yoyeserera, koma voteji ya resonance ndi yayikulu kuposa voteji yoyeserera.Tikudziwa kuti kusakhulupirika resonance voteji dongosolo ndi vertex wa parabola, kutanthauza, pamene parabola kukwera kwa Mu ndondomeko ya vertex kapena vertex kutsika, padzakhala mfundo kuti n'zogwirizana ndi mayeso voteji mfundo.Tiyenera kuyesa buku mayeso pafupipafupi kutembenuka mndandanda resonance, ndi ntchito Buku pafupipafupi kufufuza kupeza pafupipafupi mfundo zogwirizana ndi voteji ntchito ndiyeno kupirira voteji kuthetsa vuto overvoltage m`kati kupeza mfundo resonance.
