Qalabaynta foornada dhalaalaysa: shunt

Shunt: waxaa loo adeegsaday in lagu muujiyo DC hadda, ku xiran ammeter si loo muujiyo

Ujeeddo: Qiime go’an oo go’an waa shunt dibadda ah oo ku habboon in lagu cabbiro DC hadda ka hooseysa 10kA oo si toos ah ugu shaqeynaya aaladda muujinta analogga si loo ballaariyo cabbirka cabbirka hadda ee DC, ama waxaa loo tixgelin karaa inuu yahay mid hadda ku jira wareegga isku xiga resistor -ka caadiga ah ee loo adeegsado sampling -ka waxaa loo tixgelin karaa inuu yahay calaamadda analogga ee heerka koowaad ee hadda loo isticmaalo cabbirka.

Qodobada ugu muhiimsan farsamada

1. Darajada saxnaanta: 2 ～ 4000A; 0.5 darajo: 5000 ～ 10000A; 1 darajo.

2. Xaalada deegaanka: -40 ～+60 ℃, heerkulka qaraabada ≤95% (35 ℃).

3. Waxqabadka xad -dhaafka ah: 120% hadda la qiimeeyay, 2 saacadood.

4. Hoos -u -dhaca danab: 50mV60mV70mV100mV

5. Kulaylka culeyska saaran: Ka dib marka heerkulku kor u kaco, xadka hadda lagu qiimeeyo ee ka hooseeya 50A kama badna 80 ° C; heerka lagu qiimeeyo ee kor ku xusan 50A kama badna 120 ° C.

Jaantuska jadwalka ee fiilooyinka shunt

Taxadarka

1. Wax iska caabin ah oo macmal ah looma oggola xiriirka ka dhexeeya fiilada (ama baarka naxaasta) ee wareegga koowaad ee shunt iyo shunt. Barta sampling-ka ee danabka labaad lagama soo qaadi karo meel aan muunad ahayn.

2. Waxaa lagu talinayaa in hadda dhabta ah ee la isticmaalay (muddo dheer) aysan dhaafin 80% hadda la qiimeeyay.
