Shunt Resistor for KWH Meter

1. Incazelo Ejwayelekile

I-Shunt ingenye yenzwa yamanje eyinhloko esetshenziswa kumitha ye-kWh, ikakhulukazi kumitha yesigaba esisodwa se-kWh.
Kunezinhlobo ezi-2 ze-shunt-Braze weld shunt kanye ne-electron beam shunt.
I-Electron beam weld shunt ingumkhiqizo omusha wobuchwepheshe.
I-EB weld inesidingo esiqinile sezinto zokwakha ze-mangan nezethusi, i-shunt ye-EB weld isezingeni eliphezulu.
I-EB shunt ithandwa kakhulu futhi isetshenziswa kakhulu esikhundleni se-braze weld shunt endala emhlabeni jikelele.

2. Izici

Ukunemba okuphezulu: Iphutha liku-1-5%.Kulula ukwenza ikilasi imitha elingu-1.0 ngokusebenzisa i-EB shunt
I-linerarity ephezulu: I-linerarity iphezulu ngakho-ke ukuguqulwa kwenani lokumelana lisebhendini encane.Izindleko zokukhiqiza zingancishiswa ngoba ukulinganisa kwamamitha kulula kakhulu futhi kuyashesha.
Ukuthembeka okuphezulu: I-mangan nethusi kwancibilika ukuze kube semzimbeni owodwa ngosizo lwe-electron ugongolo lwezinga lokushisa eliphezulu, ngakho-ke ithusi ne-mangan akusoze kwasuka ngesikhathi sokusebenza kwemitha.
Ukuzishisa okuncane: Ayikho i-solder phakathi kwe-copper ne-mangan, ngakho-ke akukho ukushisa okwengeziwe ku-shunt.Ithusi elisetshenziswa ku-EB shunt lihlanzekile, Inekhono elihle lokuma kwamanje;ukujiya kakhulu kwenza ukumelana nokuxhumana kukuncane kakhulu;Indawo yengxenye eyanele nendawo engaphezulu izokhipha ukushisa kwe-slef ngokushesha.
Izinga lokushisa eliphansi le-coinfidence: izinga lokushisa le-coinfidence lincane kuno-30ppm ukusuka ku--40℃–+140℃, kukhona uguquko lwenani elincane kakhulu lokumelana nezimo ezihlukene zokushisa.
Ukumelana ne-oxidation: izinto ezikhethekile zimbozwa ngethusi ukuze zivikeleke ekuphumeni kwe-oxidation.
Ukuzinza kwesikhathi eside: ukusebenza kahle kuzinzile kungakapheli iminyaka engama-20
Imelana nokushaywa kombani: Ingaphumelela ukuhlolwa kwesiteleka sombani esingu-3000A 10ms.
Usayizi omncane nesisindo esiphansi kwenza umhlangano we-shunt ube lula, izindleko zokuthutha ziphansi.
Izindleko ze-EB shunt zihlobene nesakhiwo sayo.Ukuklama okunengqondo kubalulekile ngezindleko eziphansi.
