Lwm Cov Kev Sib Txuas Hluav Taws Xob
Lwm Cov Kev Sib Txuas Hluav Taws Xob
Lub zog tswj cov cuab yeej tsim thiab tsim khoom siv hluav taws xob cov khoom siv hluav taws xob nrog qhov zoo ntawm kev xaiv yooj yim, kev ntseeg siab, tsis tshua muaj nqi, kev teeb tsa yooj yim, zoo nkauj, kev loj hlob sai, thiab lwm yam.
Lub hwj chim sib dhos ua los ntawm thyristor thiab diode uas muaj los muab:
• Ib-theem rectifier choj series: nrog rau ib-theem tag nrho tswj, ib nrab tswj, thiab rectifier choj
• Peb-theem full-bridge series: suav nrog peb-theem tag nrho tswj rectification, peb-theem ib nrab tswj rectification, thiab peb-theem rectification choj
• Rau-theem rectifier choj series: suav nrog rau-theem controllable thiab uncontrolled rectifier txuas hniav
• AC hloov series: suav nrog ib-theem thiab peb-theem AC hloov
Yog xav paub ntxiv cov lus nug ntawm lub hwj chim sib dhos ua los ntawm thyristor, diode thiab rectifier rau rectification, converting, fais fab hloov thiab tswj, thov sab laj nrog peb, pab neeg txhawb nqa cov neeg siv khoom nrog cov txuj ci thiab cov kws paub txog kev ua haujlwm tau txais kev pab.
• Cov cua txias ntawm kev sib dhos yog cua txias, cua txias, thiab dej txias nrog txhuas profile thiab cov yeeb nkab cua sov.
• Cheebtsam ntawm cov rooj sib txoos yog chav tsev fais fab, RC absorption capacitor, tiv thaiv qhov kub thiab txias, cov khoom siv dav dav lossis tshwj xeeb tswj kev ua haujlwm.
Kev Taw Qhia
- Peb-Phase anti-parallel zog chav tsev yog tsim los ntawm ob SCR txuas rau hauv kev tiv thaiv ib puag ncig ntawm txhua theem kom paub txog AC theem tswj qhov hluav taws xob.Txhua thyristor ua haujlwm rau qhov sib raug zoo thiab tsis zoo ib nrab lub voj voog.Yog li qhov sib xws ntawm qhov tsis sib xws ntawm ob qhov kev sib txuas los tiv thaiv kev sib txuas SCR tseem ceeb heev thiab cov yam ntxwv ntawm lub rooj vag thiab tuav qhov ntsuas tam sim no, thiab lwm yam. Qhov sib xws ntawm thyristors ua haujlwm yuav muab qhov zoo thiab qhov tsis zoo ib nrab nthwv dej yuav sib luag, txwv tsis pub tam sim no nrog DC tivthaiv yuav ntws los ntawm inductive featured lub cev muaj zog, lub cev muaj zog stator yuav rhuab heev, ces lub cev muaj zog windings yuav hlawv thiab lub cev muaj zog yuav puas thaum kawg.
- Runau tuaj yeem muab cov theem siab sib xws tswj thyristor thiab lwm yam 3 theem tiv thaiv kev sib txuas hluav taws xob hauv nruab nrab voltage ntawm 1200V / 3300V tab sis kuj muaj hluav taws xob siab ntawm 4500V / 6500V.
- Txhawm rau kom paub qhov muag muag thiab tiv thaiv 6kV thiab 10kV high voltage motors, nws yog ib qho tsim nyog los txuas cov SCRs hauv kev tiv thaiv ib puag ncig thiab tom qab ntawd txuas lawv hauv cov koob kom ua tiav qhov kev ua haujlwm siab voltage.Txhua theem ntawm 6kV yuav tsum muaj 6 thyristors (2 nyob rau hauv anti-parallel thiab 3 pawg nyob rau hauv series), thiab txhua theem ntawm 10kV yuav tsum tau 10 thyristors (2 nyob rau hauv anti-parallel, 5 pawg nyob rau hauv series).Nyob rau hauv txoj kev no, qhov voltage tolerated ntawm txhua thyristor yog hais txog 2000V, yog li rau pem hauv ntej thiab rov qab tsis-repetitive rated voltages VDSM thiab VRSM ntawm cov xaiv thyristor yuav tsum yog 6500V los yog saum toj no.Txhawm rau xaiv qhov ntsuas tam sim no ntawm thyristor, qhov ntsuas kev ua haujlwm tam sim no ntawm lub cev muaj zog yuav tsum raug txiav txim siab.Feem ntau, qhov xaiv tam sim no ntawm thyristor yuav tsum yog 3 mus rau 4 npaug ntawm lub cev muaj zog tam sim no.
