Fais fais hloov transformerCov teeb meem hauv av yog ib qho uas ib txwm muaj.
Ntawm lawv, feem ntau yog ntau tshaj plaws hauv av ntawm cov hlau tseem ceeb, ua rau sab hauv kev kub ntxhov, rwb rwb kev ua kom muaj roj, hloov roj hloov pauv roj. Ntau cov kev saib xyuas thiab tshawb fawb tau tsom rau qhov no.
Thiab yog tias lub hwj huam hloov pauv hluav taws xob tsis zoo? Yuav ua li cas yuav tsis ncaj ncees lawm.
Tsuas yog nyeem ib rooj plaub, nthuav zoo heev, txhua tus tuaj koom. Ib transformer, ob npaug winding, yd11. Thaum tus hloov ntawm qhov kev ntsuas siab yog kaw, kev tawm tawm ntawm cov tub ntxhais hauv av ntawm cov hluav taws xob hloov pauv ntawm qhov hluav taws xob qis dua ntawm qhov qis voltet ntawm qhov qis voltage so. Nws pom tias cov screws tau xoob ntawm qhov sib txuas ntawm cov hlau coreal coj hlau thiab hlau tub ntxhais ua rau ntawm qhov tawm ntawm cov hlau tub ntxhais hauv av xaim.
Tab sis vim li cas ho ua cov qes xim zinc oxide xub yuav tsum tau tawg? Cov hauv qab no yog cov duab sib npaug sib sib zog hluav taws xob ntawm lub transformer. Ua ntej tshaj plaws, Kuv tsis yog kev tshaj lij. Nws tsuas yog yoj tes taw.
C1 yog lub peev xwm capactse rau hauv av hauv cov hluav taws xob siab winding, thiab C12 yog lub peev xwm ntawm lub siab ntawm qhov siab thiab qhov hluav taws xob siab. Txij li thaum lub transformer qis qis qis dua yog ze rau ntawm transformer cov tub ntxhais, thaum lub transformer corely yog tiag tiag lub capacitance sab winding rau cov tub ntxhais. Txawm li cas los xij, yog tias cov tub ntxhais tsis zoo grounded, ib qho sib luag sib luag r yuav tsum yog strung ntawm C2 thiab hauv av.
Nws yog qhov meej meej vim tias nkag mus rau ntawm no R uas yuav muaj qhov pom tseeb ntawm qhov kev ntsuas hluav taws xob qis thaum lub sijhawm hloov pauv. Daim duab hauv qab no yog cov ntaub ntawv simulation ntawm qhov chaw voltage ntawm cov kev hloov hluav taws xob qis ntawm ob qho kev hloov ntawm cov hlau tseem ceeb thiab tsis zoo ntawm cov hlau txheem.
Thaum cov hlau tseem tsis zoo, lub voltage qis qis tshaj tawm cov kev txhawb nqa ntawm cov transformer nce thaum lub sijhawm kaw. Ib qho ntxiv, peb tuaj yeem pom tias ntxiv rau lub sijhawm kaw, qhov peb-ntu voltage ntawm lub transformer ntawm lub transformer tseem tuaj yeem tuav cov kev sib xws. Txawm li cas los xij, vim cov av tsis zoo ntawm cov hlau tseem ceeb, thiab qhov nruab nrab ntawm cov capacitor ntawm lub capacts thiab nruab nrab ntawm cov corpage tog yog qhov sib txuam ntawm cov qib ntawm overvoltage. Tus xub tsim yog nruab nrab ntawm cov kab qis qis thiab hauv av, yog li nws yuav tiv taus ntau qhov kev cuam tshuam ntawm tus arester.
Qhov no yog rooj plaub txaus siab, nco qab txhawb nqa cov kev tshuaj xyuas ntawm kev hloov pauv ntawm kev hloov pauv ntawm qhov tshwm sim ntawm kev tshwm sim ntawm kev ua haujlwm tsis zoo.
