Kuedzwa kweLEEM-18 AC Bridge Mufananidzo Wakaratidzwa

Kuedza kweLEEM-18 AC Bridge

Tsananguro pfupi:

Chishandiso ichi chinogona kugadzira chero rudzi rwebhiriji reAC rakaenzana kuburikidza nekubatanidza uye kufananidza zvakasununguka. Kuburikidza nekudzidza nekusimbisa musimboti wekuyera bhiriji reAC, gadzira bhiriji reAC rinoshanda kuti riyere zvikamu zvisingazivikanwi.

Kuedza
1. Dzidza uye dzidza mamiriro ekuenzanisa uye misimboti yekuyera yebhiriji reAC; simbisa mamiriro ekuenzanisa kwebhiriji reAC;
2. Kuyera capacitance uye kurasikirwa kwe dielectric; kuzvipinza kwega uye coil yayo yepamusoro uye mutual inductance nezvimwe zvikamu zvemagetsi.
3. Gadzira mabhiriji akasiyana-siyana eAC kuti zviyereswe chaizvo.

Huru tekinoroji parameters
1. Simba rakavakirwa mukati maro sosi: frequency 1kHz±10Hz, amplitude yevoltage inobuda: 1.5Vrms;
2. Chiratidziro chedhijitari chakavakirwa mukati. Chiyero cheAC voltmeter: Chiyero chevoltage yeAC: 0～2V, chiratidziro chedhijitari chetatu nehafu;
3. Mita yemafrequency edhijitari ye LED ine manhamba mana yakavakwa mukati, chiyero chekuyera: 20Hz ～10kHz, kukanganisa kwekuyera: 0.2%;
4. AC zero-pointer yakavakirwa mukati: ine dziviriro yakawandisa, isina musoro wemita; kunzwisisika ≤1×10-8A/div, inogadziriswa nguva dzose;
5. Kudzivirira ruoko rwebhiriji rakavakirwa mukati:
Ra: ine AC resistances nomwe dze1, 10, 100, 1k, 10k, 100k, 1MΩ, ine kururama kwe0.2%
Rb: Yakagadzirwa nebhokisi rekudzivirira AC re10×(1000+100+10+1+0.1)Ω, rine kururama kwe0.2%
Rn: Yakagadzirwa nebhokisi rekudzivirira AC re10K+10×(1000+100+10+1)Ω, rine kururama kwe0.2%
6. Capacitor yakavakirwa mukati, Ln ye inductance yakajairika;
Kugona kwakajairika: 0.001μF, 0.01μF, 0.1μF, kurongeka kwe1%;
Kupinza kwakajairika: 1mH, 10mH, 100mH, kurongeka kwe1.5%;
7. Kudzivirira kwakayerwa kweRx, capacitance CX uye inductance LX zvine hunhu hwakasiyana uye mashandiro zvinosanganisirwa.
