Nigute ushobora gupima igihombo cya dielectric ya transformateur

Mbere ya byose, dushobora kumva ko igihombo cya dielectric ari uko dielectric iri munsi yumurima wamashanyarazi.Kubera ubushyuhe bwimbere, bizahindura ingufu zamashanyarazi ingufu zubushyuhe kandi zirazikoresha.Iki gice cyingufu zikoreshwa cyitwa gutakaza dielectric.

Gutakaza dielectric ntibikoresha ingufu z'amashanyarazi gusa, ahubwo binashyushya ibikoresho kandi bigira ingaruka kumikorere isanzwe.Niba igihombo cya dielectric ari kinini, bizatera ubushyuhe bukabije bwikigereranyo, bikaviramo kwangirika kwizuba, bityo igihombo gito cya dielectric, nibyiza.Iyi nayo ni imwe mu ngero zingenzi zubuziranenge bwa dielectric mumashanyarazi ya AC.

Reka tuvuge uburyo twakoresha igeragezwa rya dielectric igerageza gupima igihombo cya dielectric ya transformateur.Nyuma yo gutangira igikoresho cyo gupima, igiciro kinini cyo gushiraho agaciro kwoherezwa kumashanyarazi ahinduka, kandi amashanyarazi ahinduka akoresha PID algorithm kugirango ahindure buhoro buhoro ibisohoka kubiciro byashyizweho, hanyuma umuzenguruko wapimwe uzabikora ohereza voltage yapimwe yapimye kumashanyarazi ahindagurika, hanyuma uhindure neza voltage ntoya kugirango ugere kumashanyarazi menshi.Muri ubu buryo, ukurikije igenamigambi ryiza / rihinduranya insinga, igikoresho kizahita gihita gihitamo ibyinjijwe hanyuma uhindure intera ukurikije ikizamini cyibizamini byumuzingi.

Iyo dupima igihombo cya dielectrici yumuvuduko mwinshi uhinduranya umuyaga muke hamwe nigikonoshwa cya transformateur, dukoresha uburyo bwo guhuza kugirango tupime.Nyuma yigikoresho na transformateur yingufu zahujwe neza, dukoresha inshuro zitandukanye, gupima 10kV ya voltage, hamwe nuburyo bwo guhuza.Ubu buryo bukoreshwa mugihe gito-voltage yo gupima itumanaho cyangwa itumanaho rya kabiri ryikizamini ntigishobora gukingirwa kubutaka kandi gishyizwe hasi.Igikoresho gikoresha impinduka ya Fourier kugirango uyungurure intambamyi kandi itandukanya imiraba myinshi yikimenyetso, kugirango ukore ibara rya vector kumurongo usanzwe hamwe nikizamini cyikigereranyo, ubare ubushobozi bwa amplitude, hanyuma ubare tgδ kubitandukanya.Nyuma yo gupimwa kwinshi, igisubizo giciriritse cyatoranijwe mugutondekanya.Ibipimo bimaze kurangira, umuzenguruko wo gupima uzahita utanga itegeko-hasi.Muri iki gihe, impinduka zikoreshwa mumashanyarazi zizagenda zimanuka buhoro buhoro kuri 0.
