What resonance dzenzvimbo

Ndichiverenga kunyatsogona Electrical pane imwe padanho hazvo aionekwa resonance dzenzvimbo uye voltages. Mananara aya ndiho kuri mumatunhu AC uye anogona kunge kudiwa yaida vave nhoroondo iri simulation uye simba nokuchinja matunhu uye anobatsira.

Somuenzaniso, resonance muna AC redunhu rinowanzoshandiswa redhiyo: zvirire oscillation redunhu tichifunga resonance voltage, hunobvumira kanoverengeka kuatsanangura yakaderera simba redhiyo chiratidzo, sezvo zvakafanira nokuchinja "capacitance-inductance" ari kukura anobudirira mupfungwa tsika.

Akati oscillation redunhu - ndiyo hwaro kunzwisisa kuti resonance kuitika uye (kana) kunetseka. Zviri namahwindo yemagetsi redunhu ina capacitor zvakabatana muna zvakafanana (C tangi) uye coils (inductance L). Mavari kuburikidza nedanho "kupomba" simba pamusoro capacitance electric yeminda remagineti pane kuzvipira ukabvisa inductance (nokuda pamberi resistive zvinoriumba R) nokufamba imwe maitikiro.

In resonant muoti redunhu kuramba kuti ndima kuitika vanoshingaira zvinoriumba anomirirwa R. Pane chete resonance kuitika uye resonance voltage. Ona zvinhu zvavo.

Resonance kuitika kunoitika mudunhu iri zvakafanana pamwe kushandisa capacitor uye coils, izvo ratings vanosarudzwa kuti kwazvino C uye L rikaparadzirwa. Somugumisiro «CL» kukosha kuitika mudunhu iri kupfuura akasanganiswa cheni.

Nheyo yokuvhiyiwa sezvinotevera: pa simba kumusoro, nokuchengeta kuwanda condenser (kuti aizviti dziripo voltage). Shure kwaizvozvo zvakakwana patsanura kunobva uye kupedzisa redunhu kuti dunhu kutanga muitiro pakuyerera kusvika coils. The kuitika achipfuura zvinowanisa munhu remagineti uye zvinowanisa vaizviita induction electromotive simba, oppositely rinotungamirirwa ano. kunonyanyisa kukosha kwayo zvasvika panguva zvizere kuerera kubva capacitor. Saka, izvi zvinoreva kuti vanokwanisa yose simba vaunganidza remagineti iri shandurwai inductance. Zvisinei, nokuda okuzvibatsira induction Coil inofamba pamusoro mhosva nezvimedu anomiswa.

Sezvo counterflow kubva capacitor risisipo (iye aneta), anotanga kuti zviitike recharged, asi ane zvakasiyana polarity. Somugumisiro, vose munda coils iri vatendeukira undoraira capacitor uye muitiro rinodzokorora. Nokuda kuvapo munyika resistive chinoumba R kunoitika zvishoma nezvishoma rinooma nokufamba. Saka, kuitika resonance rinoitwa.

Resonance mupfungwa kunoitika panguva dzino kubatana kwakaita resistor R, mumwe coils L uye capacitor C. An chinokosha ndechokuti simba romugove voltage dererei kupfuura capacitor uye coils (nechimwe chinhu yoga), asi kuenzana ano anodzokororwa. Zvakare, voltage uye kuitika zviri kuyaruka. Mukuru ezvinhu kuti chidzoke uye dzigadziridzwe izvi - wakaenzana inductive uye capacitive reactance. Nokudaro, impedance akawanikwa kuti tichishingaira.

Kuti uone chinobudirira netsika voltage mhiri coils uye capacitor anoshandiswa mutemo Ohm vake. Kana zviri akaenzana zvibereko coils kuitika kune ari inductive reactance (U1 = IX1). Saizvozvowo, kuitika nokuda capacitor inofanira ngazviwande kubudikidza capacitance (U2 = IX2). Sezvo dzinotevedzana maererano zvemamiriro magetsi, uye kuti resonance X1 = X2 voltage mhiri inductance uye capacitance vakaenzana. Nokudaro, kuwedzere reactive zvinoriumba, unogona kuzadzisa kuwedzera voltage U1 uye U2, apo kuramba kuramba tsika yacho EMF kunobva. Nzvimbo chikuru chikumbiro - imwe redhiyo mapurani.
