Nyob rau hauv tus txheej txheem ntawm kev khiav hauj lwm tsis muaj-load transformer, yuav muaj ib tug unavoidable phenomenon ntawm lub cev, uas yog, txiav tawm.Qhov teeb meem ntawm kev khiav hauj lwm overvoltage vim qhov kev txiav tawm ntawm Circuit Court breaker tuaj yeem tiv thaiv los ntawm kev ntsuas hauv qab no:
1. Txhim kho cov tub ntxhais hlau
Kev txhim kho cov tub ntxhais hlau muaj qee yam cuam tshuam rau kev txo qis tsis muaj kev thauj khoom tam sim no.Vim hais tias cov hlau nplaum tam sim no thiab cov hlau poob tam sim no ua ke ua qhov tsis muaj kev thauj khoom tam sim no, thiab cov hlau nplaum tam sim no yuav tsim cov hlau nplaum sib nqus, thiab cov tub ntxhais hlau poob yuav ua rau cov hlau tsis muaj tam sim no, yog li cov tub ntxhais hlau ntawm lub transformer yog qhov tseem ceeb rau txo qhov tsis muaj load tam sim no.Ntxiv kev txhim kho cov tub ntxhais cov qauv thiab txhim kho qhov zoo ntawm cov tub ntxhais hlau yog ob qho kev ntsuas.Cold-dov nplej tuaj yeem siv los hloov cov ntaub ntawv silicon steel, vim tias qhov sib nqus permeability system ntawm cov qoob loo txias yog qhov siab.Thaum lub transformer yog overhauled, cov tub ntxhais hlau yuav tsum tau soj ntsuam thiab soj ntsuam nruj me ntsis raws li cov qauv zoo.
2. Winding txais yuav hom tangled

220kV transformer yog ib qho tseem ceeb transformer.Yog hais tias txoj kev winding yog tangled winding, parasitic capacitance ntawm transformer yuav nce.Lub entangled winding yog ntxig rau lwm qhov tig ntawm winding ncaj qha ntawm cov hluav taws xob uas nyob ib sab tig, kom lub longitudinal capacitance ntawm winding nce, thiab qhov tseeb muaj peev xwm sib txawv ntawm qhov uas nyob ib sab lem yuav nce ntxiv, thiaj li hais tias nyob rau hauv lub xub ntiag ntawm qhov tshwm sim. ntawm qhov tshwm sim overvoltage, thawj qhov hluav taws xob tuaj yeem sib npaug ntawm cov lem.
3. Siv lub tshuab hluav taws xob nrog ib qho hluav taws xob sib txuas
Thaum lub sijhawm txiav tawm tam sim no, lub zog sib nqus hauv lub inductor yuav raug hloov mus rau hauv hluav taws xob lub zog kom them tus nqi capacitor.Nyob rau lub sijhawm no, yog tias qhov hloov pauv tau txuas mus rau qhov sib npaug nrog cov resistor, lub zog sib nqus hauv lub inductor tuaj yeem tso tawm.Tom qab qhov kev hloov pauv nrog kev ua haujlwm tsis sib xws raug kaw ua ntej qhov kev txiav tawm tam sim no, qhov hloov mus rau qhov tsis sib xws yog luv luv.Tom qab qhov kev txiav tawm tam sim no, tus hloov cuab yeej R84Th N resistor los ua ib qho tam sim no, kom lub zog sib nqus hauv inductor yuav noj.
