Tsib txoj kev daws teeb meem rau induction melting rauv

(1) Lub zog hluav taws xob ntawm lub qhov cub induction melting: Siv lub tshuab hluav taws xob los xyuas seb puas muaj hluav taws xob tom qab lub ntsiab hloov hluav taws xob (contactor) thiab tswj fuse, uas yuav txiav txim siab qhov muaj peev xwm ntawm kev cuam tshuam ntawm cov khoom no.

(2) Rectifier ntawm induction melting rauv: Lub rectifier siv peb-theem tag nrho tswj choj rectifier Circuit Court, uas suav nrog rau fuses ceev, rau thyristors, rau pulse transformers thiab lub freewheeling diode.

Muaj qhov taw qhia liab ntawm lub fuse ua haujlwm ceev. Feem ntau, qhov taw qhia tau thim rov qab hauv lub plhaub. Thaum lub tshuab ua kom nrawm, nws yuav tshwm sim. Qee qhov taw qhia nrawm nrawm nrawm. Thaum lub tshuab nrawm nrawm, nws yuav tau daig hauv. , Yog li txhawm rau txhim kho kev ntseeg tau, koj tuaj yeem siv lub tshuab multimeter los ntsuas qhov nrawm nrawm rau / tawm iav los txiav txim siab seb nws puas tau tshuab.

Txoj hauv kev yooj yim los ntsuas lub thyristor yog siv lub multimeter los ntsuas nws cov cathode-anode thiab rooj vag-cathode tsis kam nrog multimeter (200Ω block). Lub thyristor tsis tas yuav raug tshem tawm thaum ntsuas. Raws li ib txwm muaj, qhov kev tiv thaiv anode-cathode yuav tsum tsis muaj kawg, thiab lub rooj vag-cathode kuj yuav tsum nyob nruab nrab ntawm 10-50Ω. Loj dhau los yog me dhau qhia tias lub rooj vag ntawm thyristor no tsis ua haujlwm, thiab nws tsis tuaj yeem ua rau kev coj ua.

Qhov thib ob sab ntawm lub pulse transformer yog txuas nrog thyristor, thiab thawj sab yog txuas nrog lub ntsiab tswj lub rooj tsavxwm. Siv lub multimeter los ntsuas qhov tseem ceeb ntawm 50Ω. Lub freewheeling diode feem ntau tsis muaj qhov ua tsis tiav. Siv lub multimeter diode los ntsuas nws ob qhov kawg thaum kuaj. Lub multimeter qhia tau hais tias qhov kev sib txuas hluav taws xob poob yog li 500mV nyob rau hauv kev coj mus rau pem hauv ntej, thiab rov qab kev taw qhia raug thaiv.

(3) Inverter ntawm induction melting rauv: Lub inverter muaj xws li plaub ceev thyristors thiab plaub mem tes transformers, uas yuav raug soj ntsuam raws li cov saum toj no txoj kev.

(4) Transformers ntawm induction melting rauv: Txhua winding ntawm txhua transformer yuav tsum tau txuas nrog. Feem ntau, qhov kev tawm tsam ntawm thawj sab yog txog kaum ntawm ohms, thiab theem nrab kuj yog ob peb ohms. Nws yuav tsum tau muab sau tseg tias thawj sab ntawm lub nruab nrab zaus voltage transformer yog kev cob cog rua nyob rau hauv parallel nrog lub load, yog li ntawd nws kuj nqi yog xoom.

(5) Capacitors ntawm induction melting furnaces: Cov hluav taws xob cua sov capacitors txuas nrog rau qhov sib npaug nrog cov load tuaj yeem tawg. Cov capacitors feem ntau yog ntsia rau hauv pawg ntawm lub capacitor khib. Cov pab pawg ntawm cov capacitors tawg yuav tsum tau txiav txim siab ua ntej thaum lub sijhawm tshuaj xyuas. Tshem tawm qhov kev sib txuas ntawm lub npav npav ntawm txhua pab pawg ntawm cov capacitors thiab lub tsheb npav tseem ceeb, thiab ntsuas qhov kev tawm tsam ntawm ob lub npav npav ntawm txhua pawg ntawm cov capacitors. Feem ntau, nws yuav tsum yog infinite. Tom qab lees paub cov pab pawg tsis zoo, tshem tawm cov tawv nqaij mos ntawm txhua lub tshuab hluav taws xob cua sov capacitor ua rau lub tsheb npav, thiab xyuas ib qho los ntawm ib qho kom pom qhov tawg capacitor. Txhua qhov hluav taws xob cua sov capacitor yog tsim los ntawm plaub cores. Lub plhaub yog ib tug ncej, thiab lwm tus ncej yog coj mus rau qhov kawg cap los ntawm plaub insulators. Feem ntau, tsuas yog ib qho tseem ceeb yuav tawg. Lub capacitor tuaj yeem siv txuas ntxiv mus, thiab nws lub peev xwm yog 3/4 ntawm qhov qub. Lwm qhov txhaum ntawm lub capacitor yog cov roj to, uas feem ntau tsis cuam tshuam rau kev siv, tab sis xyuam xim rau kev tiv thaiv hluav taws.
