| Shunt Resistor ya KWH Meter 1. Kufotokozera Kwazonse - Shunt ndi imodzi mwama sensor omwe amagwiritsidwa ntchito pa kWh mita, makamaka mu gawo limodzi la kWh mita.
- Pali mitundu iwiri ya shunt-Braze weld shunt ndi electron beam shunt.
- Electron beam weld shunt ndi chinthu chatsopano chaukadaulo.
- EB weld amafunikira kwambiri manganin ndi zida zamkuwa, shunt ndi EB weld ndi yapamwamba kwambiri.
- EB shunt ndiyotchuka kwambiri ndipo imagwiritsidwa ntchito kwambiri m'malo mwa braze weld shunt yakale padziko lonse lapansi.
2. Mbali - Kulondola kwakukulu: Kulakwitsa kuli pa 1-5%. Ndikosavuta kupanga kalasi ya 1.0 mita pogwiritsa ntchito EB shunt
- Mzere wapamwamba: Mzerewu ndiwokwera kwambiri kotero kuti kusintha kwa mtengo wotsutsa kuli pa gulu lopapatiza. Mtengo wopangira ukhoza kuchepetsedwa chifukwa kuwongolera mita ndikosavuta komanso mwachangu.
- Kudalirika kwakukulu: Manganin ndi mkuwa zinasungunuka kuti zikhale m'thupi limodzi ndi mtengo wa elekitironi wotentha kwambiri, kotero kuti mkuwa ndi manganin sizidzachoka pamene mita ikugwira ntchito.
- Kudzitenthetsa pang'ono: Palibe solder pakati pa mkuwa ndi manganin, kotero palibe kutentha kwina pa shunt. Mkuwa wogwiritsidwa ntchito mu EB shunt ndi woyera, Umakhala ndi luso loyimirira; kwambiri ngakhale makulidwe kupanga kukana kukhudzana ndi kochepa kwambiri; Gawo lokwanira la gawo ndi pamwamba lidzapereka kutentha kwa slef mwamsanga.
- Chikhulupiriro chochepa cha kutentha: coinfidence kutentha ndi kochepa kuposa 30ppm kuchokera -40
- Zam'mbuyo: Kusintha kwa Hook (1P2T) KLS7-HS12L01
- Ena: Kusintha kwapang'ono kakang'ono KLS7-SMS-103-C2T
