I-LEEM-18 AC Bridge Experiment

Incazelo emfushane:

Leli thuluzi lingakha noma yiluphi uhlobo lwebhuloho le-AC elilinganiselwe ngoxhumano lwamahhala nokufanisa.Ngokufunda nokuqinisekisa isimiso sokulinganisa sebhuloho le-AC, klama ibhuloho le-AC elisebenzayo ukuze ulinganise izingxenye ezingaziwa.

Thumela i-imeyili kithi

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izivivinyo
1. Funda futhi wazi kahle izimo zebhalansi nezimiso zokulinganisa zebhuloho le-AC;qinisekisa izimo zebhalansi zebhuloho le-AC;
2. Kala amandla kanye nokulahlekelwa kwe-dielectric;i-self-inductance kanye nekhwalithi yekhoyili yayo kanye ne-mutual inductance kanye neminye imingcele kagesi.
3. Dala amabhuloho e-AC ahlukahlukene ukuze ukale ukulinganisa kwawo.

Imingcele yezobuchwepheshe eyinhloko
1. Umthombo wesignali eyakhelwe ngaphakathi: imvamisa 1kHz ± 10Hz, i-voltage amplitude ephumayo: 1.5Vrms;
2. Isibonisi sedijithali esakhelwe ngaphakathi I-voltmeter ye-AC: Ibanga lesilinganiso sikagesi we-AC: 0～2V, isibonisi sedijithali ezintathu nohhafu;
3. Imitha ye-LED yedijithali eyakhelwe ngaphakathi enamadijithi amane, ububanzi bokulinganisa: 20Hz～10kHz, iphutha lokulinganisa: 0.2%;
4. Isikhombi se-AC esakhelwe ngaphakathi: esinokuvikelwa kokugcwala ngokweqile, akukho khanda lemitha;ukuzwela ≤1 × 10-8A/div, eguquguqukayo ngokuqhubekayo;
5. Ukumelana nengalo yebhuloho eyakhelwe ngaphakathi:
I-Ra: iqukethe ukumelana kwe-AC okuyisikhombisa okungu-1, 10, 100, 1k, 10k, 100k, 1MΩ, nokunemba okungu-0.2%
I-Rb: Yakhiwe ngebhokisi elingu-10×(1000+100+10+1+0.1)Ω AC lokumelana, nokunemba okungu-0.2%
I-Rn: Yakhiwe ngebhokisi elingu-10K+10×(1000+100+10+1)Ω AC lokumelana nebhokisi, nokunemba okungu-0.2%
6. I-capacitor Cn ejwayelekile eyakhelwe ngaphakathi, inductance ejwayelekile Ln;
Amandla ajwayelekile: 0.001μF, 0.01μF, 0.1μF, ukunemba 1%;
I-inductance ejwayelekile: 1mH, 10mH, 100mH, ukunemba 1.5%;
7. Ukumelana okulinganiselwe kwe-Rx, i-capacitance CX kanye ne-inductance LX enamanani ahlukene nokusebenza kufakiwe.
