Nigute ushobora gukemura ikibazo cya overvoltage ya sisitemu yo gupima AC resonant?

Sisitemu yo gupima inshuro ya AC resonant ikoreshwa mukumenya imbaraga zo kubika ibikoresho byamashanyarazi.Nibyingenzi byingenzi mugusuzuma niba ibikoresho byamashanyarazi bishobora gukoreshwa.Nuburyo kandi bwingenzi bwo kwemeza urwego rwibikoresho no kwirinda impanuka.Kuberako inshuro zihinduranya za rezonanse yikizamini gishobora kwerekana neza uko ibintu byifashe byamashanyarazi bikorera munsi ya voltage ya AC, birashobora rwose kubona neza inenge.

HV HIPOT GDTF yuruhererekane rwa Frequency Guhindura AC Sisitemu Yikizamini

Bitewe nihame rya resonance ryemejwe nigikoresho cyo guhinduranya inshuro ya rezanse yikizamini, voltage yumurongo runaka muri sisitemu ya loop hamwe na capacitance na reaction muri loop bitanga resonance.Umuvuduko ukabije wa capacitor ugera kuri voltage yikizamini.

Ukurikije amahame yavuzwe haruguru hamwe nikibazo nyirizina cyibizamini kurubuga, kurenza urugero rwumuvuduko wuruhererekane rwimikorere ya rezanse mubisanzwe bibaho mubihe bibiri, kimwe nigihe igikoresho gishakisha aho cyumvikanisha hamwe nuburyo bwo kubyara ingufu za resonance;ikindi nigihe imbaraga zo kongera imbaraga zigeze kuri voltage yikizamini.mu rubanza rwa.

Kubijyanye no gushakisha ingingo ya resonance mukurikirane rya rezonanse no kuyizamura kuri voltage yikizamini, mubisanzwe mugihe umuyaga wihanganira ibicuruzwa byibizamini utujuje ibyangombwa cyangwa ibidukikije byaho bitigeze bihinduka cyane, ikizamini ntikizatanga uburinzi burenze urugero cyangwa andi makosa.Nyamara, kubera ko umuyagankuba wa gride udahoraho kandi n’umubyigano winjiza wamashanyarazi uhindagurika, ibisohoka n’umuriro mwinshi nabyo bifite ihindagurika runaka, bishobora gutera uburinzi burenze urugero kuri voltage.Niba amashanyarazi atanga amashanyarazi ahindagurika, urashobora guhindura uburinzi burenze urugero bwigikoresho, hanyuma ugashyiraho uburinzi burenze urugero agaciro kagereranijwe.Mubisanzwe turasaba kurinda overvoltage gushyirwaho inshuro 1.1-1.2 kurinda voltage.Muri iki gihe, mubyukuri ntakibazo gishyirwa inshuro 1,2.

Ibyavuzwe haruguru nikibazo cyoroshye, ariko biragoye kumihindagurikire ya voltage kugirango itere imbaraga zumuriro zibaho mugihe hashyizweho uburyo bwo gukingira amashanyarazi.Mubisanzwe, overvoltage yumurongo woguhindura urukurikirane rwibizamini bya resonance igikoresho kiri murwego rwohanagura igikoresho, ni ukuvuga mugikorwa cyo gushakisha ingingo ya resonance.Umuntu uwo ari we wese wakoresheje ibikoresho byo kwipimisha inshuro nyinshi byifashishwa mu gupima ibizamini azi ko mugikorwa cyo gushakisha icyerekezo cya rezonanse yikurikiranabikorwa ryikurikiranya ryikizamini, voltage na frequency bifite isano imwe na parabola.Mburabuzi, sisitemu isanga voltage iri hejuru, ni ukuvuga vertex ya parabola, nka point ya resonance.Kubera ko amahame ya rezonanse ashobora kumvikanisha ingufu za voltage nkeya inshuro 80 (bitewe nubuziranenge hamwe nubundi busabane muri rusange ntibirenza inshuro 30), voltage isabwa mugukwirakwiza inshuro nyinshi ibikoresho byo gupima resonance yibikoresho ni 20 -50V, na voltage nyuma yo kwishima muri rusange kuri volt magana.Binyuze mu mahame yavuzwe haruguru, twasanze niba niba voltage yikizamini cyibicuruzwa dukeneye ari munsi ya voltage mugihe sisitemu resonance ari point ya resonance, sisitemu irashobora kugira uburinzi burenze urugero mugihe ihita ishakisha ingingo ya resonance.Muri iki gihe, ibikoresho byose byahinduwe byuruhererekane rwibikoresho ntibishobora kwihanganira igitutu, ikizamini ntigishobora kurangira.

Igisubizo cyiki kibazo nacyo kiragoye.Ntabwo aruko impinduka zikurikirana zikurikirana resonance igikoresho ntigishobora kubyara voltage yikizamini, ariko voltage ya resonance irenze igipimo cyikizamini.Turabizi ko isanzwe ya resonance voltage ya sisitemu ari vertex ya parabola, nukuvuga, iyo parabola yazamutse Kuri gahunda ya vertex cyangwa vertex imanuka, hazabaho ingingo ijyanye nikizamini cya voltage point.Tugomba gusa kugerageza ikigeragezo cyamaboko ya seriveri yo guhinduranya imirongo ya rezonanse, kandi tugakoresha intoki zishakisha kugirango tubone umwanya wumurongo uhuye na voltage yakoreshejwe hanyuma uhangane na voltage kugirango dukemure ikibazo cyumubyigano mwinshi mugushakisha aho resonance ihinduka.
