Kungiyar Campbell: Ta’rifin da Funtukan
Ta’rifin
Kungiyar Campbell shi ne kungiya mai kyau na tsarin lalace mai yiwuwa don linadda masu hanyoyin inductance. Hanyoyin inductance yana nufin alamomin dukkan ciki wanda ya faru a kan tsafta ta haka ya haɗa electromotive force (emf) da kuma, saboda haka, ciki a tsafta na musamman. Wannan kungiya ba zai iya amfani da shi don samun hanyoyin inductance kawai, amma zai iya amfani da shi don linadda frequency. Ana yi wannan tare da linadda hanyoyin inductance har zuwa lokacin da aka samu null point a cikin kungiyar.
A ingantattun kirkiyoyin lalace, linadda hanyoyin inductance mai kyau ita ce muhimmiyar don fahimtar tashadaddinsu ga tsaftooyi a cikin kungiyoyi, kamar a transformers, inductive coupling systems, da kuma abubuwan kirkiyoyin lalace. Kungiyar Campbell ya ba da rike da inganci don wasu linadduka. A lokacin da ake amfani da shi don linadda frequency, na'amuddukan null - point detection principle ya ba aiki da suka biye don tabbatar da dalilai game da hanyoyin inductance setting da frequency na signal na lalace da ake bayyana.
Wata na biyu yana nuna ma'anarta hanyoyin inductance, wanda ke jin dadin rayuwar kungiyar Campbell.

Bayyana:

• M1 na nufin hanyoyin inductance mai saukar

• L1 ana nufin self - inductance na tsafta na musamman na hanyoyin inductance M1

• M2 na nufin standard hanyoyin inductance mai yawan canza

• L2 ana nufin self - inductance na tsafta na musamman na hanyoyin inductance M2

• R1, R2, R3, R4 ana nufin non - inductive resistances

Samun balancin kungiyar Campbell ya bukaci a yi da labaran yanayi:

Yanayi 1: Hasashe na Biyu da Balancin Daɗi

A lokacin da ake hasasa, ana haɗa detector a kan points ‘b’ da ‘d’. A wannan hali, kungiyar ya fi shiga hankalin kungiyar self - inductance comme

• Balancin Daɗi Don haɗa kungiyar zuwa balancin a tara na biyu, ana canza resistors R3 ko R4, da kuma R1 da R2. Wannan prosesi na canza ya ba da rike da linadda electrical parameters na kungiyar, don haka za ta iya hasa potential differences across the relevant parts of the bridge, kamar a yi canza weights on a balance scale to achieve equilibrium.

• Balancin Tafi A tara na uku, ana haɗa detector a kan points b' da d'. Ba da canzan da aka yi a tara na daɗi, ana canza variable standard mutual inductance M2 da kuma. Daga baya a yi canza M2 saboda cewa an haɗa canzan resistors, electrical configuration na kungiyar ya zama da kyau. Ya kai, za a samu balancin, wanda ya nuna cewa kungiyar ta samu balancin inda electrical signals a cikin kungiyar suna fi shiga harmony, da kuma za a iya samun linadda mai kyau na hanyoyin inductance mai saukar M1.
