Zolemba Zamalonda
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 wotentha wa ma elekitironi, kotero kuti mkuwa ndi manganin sizidzachoka pakugwira ntchito kwa mita.
- Kudziwotcha 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:kutentha coinfidence ndi kochepa kuposa 30ppm kuchokera -40
- Zam'mbuyo: Shunt Resistor ya KWH Meter KLS11-LM-PFL
- Ena: Omni-direction mini maikolofoni MM4015-High Sensitivity Serie KLS3-MM4015P
