Shunt Resistor rau KWH Meter

1. Cov lus piav qhia dav dav

Shunt yog ib qho tseem ceeb tam sim no sensor siv nyob rau hauv kWh meter, tshwj xeeb tshaj yog nyob rau hauv ib theem kWh meter.
Muaj 2 hom shunt-Braze weld shunt thiab electron beam shunt.
Electron beam weld shunt yog cov khoom siv thev naus laus zis tshiab.
EB weld muaj qhov yuav tsum tau nruj me ntsis rau cov khoom siv manganin thiab tooj liab, shunt los ntawm EB weld yog qhov zoo.
EB shunt yog ntau thiab nrov dua thiab siv dav los hloov cov qub braze weld shunt thoob ntiaj teb.

2. Nta

High precision: yuam kev yog ntawm 1-5%.Nws yog ib qho yooj yim los ua haujlwm tawm hauv chav kawm 1.0 meter los ntawm kev siv EB shunt
High linearity: Lub linearity siab yog li qhov kev hloov pauv tus nqi yog nyob ntawm qhov nqaim.Tus nqi tsim khoom tuaj yeem txo qis vim tias qhov ntsuas ntsuas ntsuas tau yooj yim thiab nrawm.
Kev ntseeg siab: Cov manganin thiab tooj liab tau yaj mus rau hauv ib lub cev los ntawm cov hluav taws xob kub kub, yog li cov tooj liab thiab manganin yuav tsis tawm mus thaum lub sijhawm ua haujlwm ntawm lub ntsuas.
Cov cua sov ntawm tus kheej me me: Tsis muaj qhov sib txuas ntawm tooj liab thiab manganin, yog li tsis muaj cua sov ntxiv rau ntawm shunt.Cov tooj liab siv hauv EB shunt yog ntshiab, Nws muaj peev xwm sawv tam sim no;heev txawm thickness ua rau kev tiv thaiv yog qhov tsawg tshaj plaws;Qhov seem seem txaus thiab thaj chaw saum npoo yuav muab tawm cov cua sov sai sai.
Tsis tshua muaj kub coinfidence: kub coinfidence yog me dua 30ppm los ntawm -40 ℃ ~ + 140 ℃, muaj me me kuj tsis tshua muaj nqi hloov nyob rau hauv txawv kub tej yam kev mob.
Resistant oxidation: cov khoom tshwj xeeb yog coated rau ntawm tooj liab los tiv thaiv oxidation
Lub sij hawm ntev stability: qhov kev ua tau zoo yog ruaj khov nyob rau hauv 20 xyoo
Resistant rau xob laim tawm tsam: Nws tuaj yeem xeem dhau ntawm 3000A 10ms xob laim kev sim.
Qhov me me thiab qhov hnyav qis ua rau lub shunt sib dhos yooj yim dua, thauj tus nqi qis dua.
EB shunt tus nqi cuam tshuam nrog nws cov qauv.Tsim nyog tsim yog ib qho tseem ceeb rau tus nqi qis.
