Ndi zovuta ziti zomwe ziyenera kutsatiridwa pakuyesa mayamwidwe a polarization index?

Zoyenera kuyeza kuchuluka kwa mayamwidwe

The mayamwidwe chiŵerengero ndi polarization index wa thiransifoma ndi voteji kalasi ya 10kv ndi mphamvu ya kugawa maukonde thiransifoma m'munsimu 4000kvA sangathe anayeza.

Pamene mulingo wamagetsi wa transformer ndi 220kv kapena kupitilira apo ndipo mphamvuyo ili pamwamba pa 120MVA, choyezera kukana cha 5000V chiyenera kugwiritsidwa ntchito kuyeza kuchuluka kwa mayamwidwe.Chiŵerengero cha mayamwidwe sikuyenera kukhala pansi pa 1.5 kutentha kwa chipinda.Pamene kukana kwa insulation kuli kwakukulu kuposa 10000MΩ pa R60min, index polarization siyofunika.

Mavuto otsatirawa akuyenera kutsatiridwa pakuyesa mayamwidwe a polarization index

(1) Muyezo uliwonse ayenera kusankha voteji mlingo kutchinjiriza kukana tester, opanga osiyana alibe mphamvu;

(2) Pakuyezera, mzere wapamwamba wa voteji uyenera kusankhidwa ngati mzere wapadera wotetezera magetsi, ndipo mzere wa L ndi N sungathe kusinthanitsa, mzere woyesera sayenera kuvulazidwa ndi kuyimitsidwa momwe zingathere;

(3) Pofuna kupewa zotsalira zotsalira kuti zisamakhudze zotsatira za mayesero, chinthu choyesedwa chiyenera kutulutsidwa mokwanira chisanachitike;

(4) Musanayambe kuyesedwa, chotsani waya woyesera, pukutani cholowa choyesera ndikuonetsetsa kuti nthaka ndi yodalirika;

(5) Kupewa chikoka cha kutayikira padziko pano mmene ndingathere mu mpweya chinyezi ndi yaing'ono mayeso, ngati n'koyenera kulumikiza chishango mphete;

Zomwe zili pamwambazi ndizovuta zomwe ziyenera kutsatiridwa poyesa mayamwidwe a polarization index.M'pofunika kulabadira kusankha voteji kwa zida mphamvu.Iyenera kukhala yogwirizana ndi zoyeserera.
