Lub hwj chim regulator yog ib lub vaj huam sib luag -mounted power adjustment unit uas siv thyristors (tseem hu ua silicon-tswj rectifiers) thiab lawv cov trigger control circuits los kho lub load zog.
Thyristors (tseem hu ua silicon{0}}tswj rectifiers, abbreviated li SCR), uas ua lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob, tau siv dav hauv ntau qhov chaw tsim khoom thiab tau dhau los ua ib qho khoom siv tsis tseem ceeb rau automation.
Hauv kev tswj qhov kub thiab txias tsis ntev los no, kev siv thyristors tau pom tseeb dhau los. Txawm li cas los xij, muaj cov npe sib txawv rau hauv Suav teb, xws li thyristor regulator, silicon tswj rectifier regulator, thyristor tswj ntsuas, silicon tswj rectifier tswj ntsuas, thyristor voltage regulator, silicon tswj rectifier voltage regulator, thyristor hwj chim regulator, silicon tswj rectifier fais fab fais fab regulator, voltage regulator, voltage regulator. tswj ntsuas, silicon tswj rectifier AC fais fab tswj ntsuas, lub hwj chim regulator, lub hwj chim tswj ntsuas, voltage regulator, voltage tswj ntsuas, thiab lwm yam. Ib lub npe yog lub hwj chim regulator, uas kuj yog ib lub npe nrov nyob rau hauv Suav teb.
Cov ntaub ntawv no nthuav tawm kev lag luam thiab txhim khu kev qha fais fab kev tswj hwm. Peb -theem thyristor fais fab thiab voltage regulator siv digital circuits los ua thyristors, ua kom muaj hluav taws xob tswj thiab tswj fais fab. Kev tswj hluav taws xob txais yuav ib theem- hloov pauv hom, thaum lub hwj chim tswj muaj ob txoj kev xaiv: tsau- lub voj voog hluav taws xob tswj thiab sib txawv- lub voj voog hluav taws xob tswj.
Lub rooj tsav xwm tswj tau ua ke nrog ntau yam kev ua haujlwm, suav nrog theem- xauv lub voj (PLL) synchronization Circuit Court, tsis siv neeg theem kev ntxub ntxaug, theem- kev tiv thaiv tsis ua haujlwm, muag muag muag, muag muag muag, kub dab dej tshaj - ntsuas kub, qhov tso zis tsis tu ncua, kev txwv tam sim no, dhau- kev tiv thaiv tam sim no, thiab kev tiv thaiv tam sim no.
Muaj ob txoj hauv kev ua rau lub rooj tsavxwm tswj: ncaj qha cuam tshuam ntawm thyristor modules thiab ua rau theem -hloov hom khoom- xeev relays (SSRs).
Cov yam ntxwv tseem ceeb ntawm pawg tswj hwm: 12-ntsis A / D converter, siab tso tawm linearity, thiab qis tso zis pib tswj taw tes.
Peb -theem fais fab tswj hwm muaj lub rooj tsavxwm, lub tshuab ua kom sov siab, lub kiv cua txias, lub thawv ntim khoom, thiab lwm yam khoom. Lub hauv paus tseem ceeb suav nrog pawg tswj hwm, thyristor module lossis lub tiaj tus thyristor sib dhos, thiab lub vaj huam sib luag ua haujlwm nrog kev sib txuas lus ua haujlwm; cov cua kub dissipation system txais kev ua haujlwm siab - ua haujlwm kub dissipation thiab qis- suab nrov cua txias kiv cua. Tag nrho chav ua ke ua ke tag nrho cov haujlwm ntawm pawg tswj hwm. Lub peev xwm tam sim no ntawm chav tsev nyob ntawm 25A txog 3000A.
Lub hwj chim regulator yog siv ua ke nrog ib tug ntse PID regulator los yog PLC nrog 0-12V thiab 4-20mA teeb liab; nws yog tsuas yog siv rau kev tswj cua sov ntawm cov tshuab hluav taws xob hauv tshuab hluav taws xob, thiab muag muag- pib lub zog- txuag kev tswj hwm ntawm cov kiv cua loj thiab cov twj tso kua dej. Cov hom kev thauj khoom tuaj yeem yog peb-theem resistive loads, peb-theem inductive loads, thiab peb-theem transformer loads; qhov peb -theem loads tuaj yeem ua rau nruab nrab- loads hauv av, nruab nrab-ungrounded loads, internal delta-connected loads, thiab external delta-connected loads.
