Waa maxay dhibaatooyinka ay tahay in fiiro gaar ah loo yeesho cabirida saamiga nuugista index

Shuruudaha lagu cabbirayo saamiga nuugista

Qiyaasta nuugista iyo index polarization ee transformer-ka oo leh heerka korantada ee 10kv iyo awoodda isweydaarsiga shabakadda qaybinta ee ka hooseeya 4000kvA lama cabbiri karo.

Marka heerka korantada korantadu uu yahay 220kv ama ka badan oo awooddu ay ka sarreyso 120MVA, tijaabiyaha iska caabbinta 5000V waa in loo adeegsadaa si loo cabbiro saamiga nuugista.Saamiga nuugista waa inuusan ka yarayn 1.5 heerkulka qolka.Marka qiimaha caabbinta dahaarka uu ka weyn yahay 10000MΩ at R60min, index polarization looma baahna.

                                   GD3126A (GD3126B) Tijaabada iska caabbinta dahaadhka 5kV/10TΩ (10kV/20TΩ)

Dhibaatooyinka soo socda waa in fiiro gaar ah loo yeelo marka la cabbirayo tusaha saamiga nuugista

(1) Cabbir kasta waa inuu doortaa tijaabiyaha iska caabbinta heerka korantada ee isku midka ah, soosaarayaasha kala duwani wax saameyn ah kuma laha;

(2) Inta lagu jiro cabbiraadda, xariiqda wax-soo-saarka tamarta sare waa in loo doortaa sida khad gaashaan oo sare oo gaar ah, iyo xariiqda wax-soo-saarka L iyo N lama isweydaarsan karo, xariiqda tijaabada waa in aan la dhaawacin oo la hakin inta suurtogalka ah;

(3) Si looga hortago kharashka haraaga ah inay saameyn ku yeelato natiijooyinka baaritaanka, walaxda la tijaabiyay waa in si buuxda looga saaro baaritaanka ka hor;

(4) Tijaabada ka hor, ka saar siliga tijaabada, tirtir isku-dhafka tijaabada oo nadiif ah oo hubi in dhulku yahay mid la isku halayn karo;

(5) Si aad uga hortagto saameynta qulqulka dusha sare ee hadda jira ilaa inta suurtogalka ah ee qoyaanka hawada waa tijaabo yar, marka loo baahdo in lagu xiro giraanta gaashaanka;

Kuwa kore waa dhibaatooyinka ay tahay in fiiro gaar ah loo yeesho marka la cabbirayo tusaha saamiga nuugista.Waa lagama maarmaan in fiiro gaar ah loo yeesho xulashada tamarta qalabka korontada.Waa inay ahaataa mid waafaqsan qeexida imtixaanka.
