Ndi kupita patsogolo kwa sayansi ndi luso lamakono, makampani opanga zamagetsi ayambanso pang'onopang'ono.M'mbuyomu, mitundu yochepa chabe yamagetsi osavuta amatha kupangidwa, pomwe pakali pano, pali zinthu zosiyanasiyana, zovuta komanso zosakhwima zamagetsi.Mosakayikira, ntchito zosiyanasiyana za zinthu zamagetsi sizingatheke popanda zida zamagetsi.Pazigawo zamagetsi, pali mtundu wa resistor wotchedwa varistor, womwe ndi wotsutsa wokhala ndi mawonekedwe osagwirizana ndi volt-ampere, ndipo kukana kwake kumasintha ndi kusintha kwa magetsi mkati mwamtundu wina wamagetsi.
Pamene voteji mu dera lalikulu kwambiri, ndivaristorimapanga ma voltage clamping kuti azitha kuyamwa mopitilira muyeso ndikuteteza dera ndi zida zina zamagetsi, chifukwa chake amagwiritsidwa ntchito kwambiri pamakina opangira magetsi, makina otetezera, zida zapakhomo ndi zina.
Popeza varistor amayamwa mafunde akuluakulu mu dera kwa nthawi yaitali, n'zosavuta kuyambitsa kuwonongeka kwa ntchito ndi kukalamba kwa varistor.Chifukwa varistor ali ndi parasitic capacitance yayikulu, ikagwiritsidwa ntchito poteteza mphamvu yamagetsi ya AC, nthawi zambiri imatulutsa kutayikira kochulukirapo pakugwira ntchito mwachizolowezi.Kuchulukirachulukira kwakanthawi kumakhudza magwiridwe antchito adongosolo ndikuyambitsa mavuto.
Kuti athetse vutoli, varistor ndi chubu chotulutsa mpweya zimagwirizanitsidwa mndandanda.Chubu chotulutsa mpweya chimakhalanso ndi mphamvu ya parasitic, koma mphamvu ya parasitic ya chubu yotulutsa ndi yaying'ono kwambiri.Pambuyo polumikizidwa mndandanda ndi varistor, mphamvu yonse ya nthambi yonse yotsatizana ikhoza kuchepetsedwa kukhala ma microfarads ochepa.
Mu mndandanda wa nthambi kuphatikiza, mpweya kumaliseche chubu amachita ngati lophimba, amene akhoza kulekanitsa varistor ku dongosolo pansi ntchito yachibadwa ya dongosolo, kotero kuti pafupifupi palibe kutayikira panopa umayenda mwa varistor, kuchepetsa otaya voteji.Mphamvu yamagetsi ndi kutayikira kwa varistor sikungachuluke, zomwe zimachepetsa kukalamba kwazomwe zimachitika chifukwa cha kutayikira komwe kukuyenda kwa nthawi yayitali.
Komanso, pamene varistor ndi mpweya kutulutsa chubu ntchito mndandanda, akhoza kuchepetsa linanena bungwe kukakamiza yotsalira, kusintha mphamvu panopa, ndi kutalikitsa nthawi ntchito.
JYH HSU(JEC) Electronics Ltd (kapena Dongguan Zhixu Electronic Co., Ltd.) ndi amodzi mwa opanga zazikulu kwambiri ku China potengera kupanga kwapachaka kwachitetezo cha capacitor (X2, Y1, Y2).Mafakitole athu ndi ISO 9000 ndi ISO 14000 satifiketi.Ngati mukuyang'ana zida zamagetsi, talandiridwa kuti mutilankhule.
