Chifukwa chiyani AC Resonant Test System imapanga overvoltage?

Kuchuluka kwa mphamvu ya chinthu choyesedwa komanso kutayikira kwa thiransifoma yoyeserera, ndizodziwikiratu kuti capacitance ikukwera.Choncho, pamene ife kuchita AC kupirira voteji mayeso a mndandanda resonance lalikulu-mphamvu mayeso chinthu, m'pofunika mwachindunji kuyeza voteji kumapeto kwa mayeso chinthu kupewa mayeso chinthu kugonjetsedwa kwambiri voteji.

The overvoltage chodabwitsa cha mndandanda resonance test chipangizo amayamba ndi zinthu zotsatirazi:

(1) Kumangirira koyambirira kumakanikizidwa mwadzidzidzi m'malo mokwera pang'onopang'ono kuchokera ku zero voltage.
(2) Mphamvu yamagetsi ikadali yokwera, dzimitsani magetsi mwadzidzidzi, m'malo mongotsika mpaka ziro, ndiyeno kudula magetsiwo.Zitha kuwoneka kuchokera pakusintha kwa thiransifoma yokhotakhota kuti zinthu ziwiri zomwe zili pamwambazi zingayambitse kuchulukirachulukira kwazinthu zomwe zayesedwa, zomwe siziloledwa.

Kwa (1) kutsekedwa ndi dera lowongolera kuti ma voliyumu omwe siazero asapanikizidwe mwadzidzidzi.
Kwa (2) njira yoyenera yogwirira ntchito iyenera kutsatiridwa mosamalitsa kuti mupewe.
(3) Nkhani yoyesera imawonongeka mwadzidzidzi.Izi nthawi zambiri zimakumana ndi zosapeŵeka.Ngati mapeto a thiransifoma otuluka amalumikizidwa mwachindunji ndi chinthu choyesedwa, pamene chinthu choyesedwa chikawonongeka mwadzidzidzi, kuthekera kwa kutuluka kwa thiransifoma kumakakamizidwa nthawi yomweyo kuti ziro, zomwe zikufanana ndi zochitika zadzidzidzi pamtunda. Mapeto a thiransifoma yoyesera - kutsogolo kwa mafunde kumakhala kotsetsereka kwambiri Phindu lapamwamba la mphamvu yamagetsi yamagetsi ndilofanana ndi mtengo wanthawi yomweyo wamagetsi oyesera a chinthu choyesera, koma polarity ndi yosiyana.Izi zidzapanga ma overvoltages owopsa pachitetezo chotalikirapo cha ma windings a thiransifoma.

Njira yopewera ndiyo kulumikiza chopinga chodzitchinjiriza chokhala ndi mtengo wokwanira wokana mndandanda pakati pa thiransifoma potuluka kumapeto kwa chipangizo chamagetsi pafupipafupi cha resonance test ndi chinthu choyesera, kotero kuti mphamvu yamagetsi ya polarity yosiyana imagwira ntchito pamagawo angapo. chitetezo chotsutsa ndi cholowera cha transformer capacitance.Kwa nthawi yochepa, magetsi ambiri amatsika pachitetezo choteteza.
