Njira yopezera resonance point mu mayeso a cable series resonance test

Mayeso a chingwe cha resonance amatanthawuza kuyesa kwa AC kupirira ma voliyumu a chingwe pogwiritsa ntchito chipangizo choyesera cha resonance.Kuphatikiza apo, chipangizochi chitha kuyesanso zoyezera pa ma transfoma, GIS, ndi zida zamagetsi kupatula mphamvu yayikulu.

Komabe, pochita mayeso amtunduwu, nthawi zambiri timakumana ndi mavuto osiyanasiyana, monga njira yolumikizira waya, kupeza resonance point, vuto la flashover, etc. Chipangizo choyesera cholumikiziranso chomwe timagwiritsa ntchito chidapangidwa molingana ndi magawo aukadaulo omwe amasinthidwa ndikupangidwa, kotero iwo sizigwirizana kwathunthu.Pachifukwa ichi, pazida zazing'ono zamagetsi, tidzafotokozera zifukwa zazikulu ndi zothetsera kusowa kwa mfundo za resonance mu chikho cha resonance.

Ngati tikufuna kuthetsa vutolo kuti mfundo ya resonance singapezeke mu mndandanda wa resonance, choyamba, tiyenera kumvetsetsa lingaliro ndi njira ya mndandanda wa resonance: ikhoza kusinthidwa.Kukula kwa resonant kumasinthidwa, ndipo resonance imapangidwa ndi inductor L ndi capacitor C. Chochitika cha resonance chimapezeka nthawi imodzi kapena zingapo.Izi zikutanthauza kuti, ngati resonance ya mndandanda ikufuna kupanga "voltage ya resonant", ma frequency amasinthidwa kuti apange capacitive reactance ndi inductive reactance.

Ngati simukumvetsa mikhalidwe ya resonance, mutha kuyang'ana kaye zomwe zimalumikizana ndi resonance ndi zomwe zili zofanana.
Chifukwa chachikulu chomwe nsonga ya resonance sichitha kupezeka muzing'onozing'ono zamagulu ang'onoang'ono a resonance ndikuti mphamvu ndi yaying'ono kwambiri ndipo kuyankhidwa ndi kwakukulu kwambiri, zomwe zimapangitsa kuti chikhalidwe cha resonance chipitirire maulendo amtundu wa resonance ndipo mfundo ya resonance singapezeke.Ikhoza kuthetsedwa ndi njira ziwiri zotsatirazi: mu mndandanda wa resonance test device The compensation capacitor imagwirizanitsidwa mofanana mu loop, ndipo mndandanda ndi njira zofanana za riyakitala zimasinthidwa kuti zichepetse kapena kuonjezera inductance.
