Ulwazi lweMveliso

I-Shunt Resistor ye-KWH Meter

1. Inkcazo ngokubanzi

I-Shunt yenye yoluvo oluphambili lwangoku olusetyenziswa kwimitha ye-kWh, ngakumbi kwisigaba esinye semitha ye-kWh.
Kukho iintlobo ezi-2 ze-shunt-Braze weld shunt kunye ne-electron beam shunt.
I-Electron beam weld shunt yimveliso entsha yetekhnoloji.
I-EB weld inemfuno engqongqo kwi-mangan kunye nezixhobo zobhedu, i-shunt nge-EB weld ikumgangatho ophezulu.
I-EB shunt ithandwa ngakumbi kwaye isetyenziswa kakhulu ukuthatha indawo ye-braze weld shunt endala kwihlabathi jikelele.

2. Iimpawu

Ukuchaneka okuphezulu: Impazamo ikwi-1-5%. Kulula ukusebenzela iklasi eyi-1.0 yeemitha ngokusebenzisa i-EB shunt
I-linerarity ephezulu: I-linerarity iphezulu ngoko ke utshintsho lwexabiso lokumelana lukwibhendi emxinwa. Iindleko zemveliso zinokucuthwa kuba ukulinganisa imitha kulula kakhulu kwaye kuyakhawuleza.
Ukuthembeka okuphezulu: I-manganin kunye nobhedu lwanyibilikiswa ukuba lube kumzimba omnye ngobushushu obuphezulu be-electron beam, ngoko ke ubhedu kunye ne-mangan azinakuze zimke ngexesha lokusebenza kwemitha.
Ukuzifudumeza okuncinci: Akukho solder phakathi kobhedu kunye ne-mangan, ngoko akukho bushushu bongezelelweyo kwi-shunt. Ubhedu olusetyenziswa kwi-EB shunt lusulungekile, lunekhono elihle lokuma okwangoku; kakhulu ngokulinganayo ukutyeba kwenza ukuxhathisa umfowunelwa yeyona incinci; Indawo yecandelo elaneleyo kunye nommandla womhlaba uya kunika ubushushu be-slef ngokukhawuleza.
I-coinfidence yobushushu obuphantsi: i-coinfidence yeqondo lobushushu incinci kune-30ppm ukusuka -40 ℃–+140℃, kukho utshintsho oluncinci kakhulu lokumelana nexabiso kwiimeko ezahlukeneyo zobushushu.
Ukumelana ne-oxidation: izinto ezikhethekileyo zigqunywe kubhedu ukuze zikhuseleke ukusuka kwi-oxidation.
Uzinzo lwexesha elide: ukusebenza kakuhle kuzinzile kwiminyaka engama-20
Ukuxhathisa kukubetha kombane: Inokuphumelela uvavanyo lwe-3000A 10ms yovavanyo lombane.
Ubungakanani obuncinci kunye nobunzima obuphantsi benza ukuba indibano ye-shunt ibe lula, iindleko zokuthutha ziphantsi.
Ixabiso le-EB shunt linxulumene nesakhiwo sayo. Uyilo olufanelekileyo lubalulekile kwiindleko eziphantsi.
