Qhov txawv ntawm din rail fais fab mov thiab switching fais fab mov yog dab tsi?

Ob qho tib si din rail fais fab mov thiab switching fais fab mov yog cov khoom siv hloov pauv fais fab, tab sis lawv txawv heev hauv kev tsim qauv, kev ua tau zoo thiab kev siv.

Lub zog fais fab din rail hloov cov input alternating current mus rau hauv qhov ncaj qha tam sim no nrog qhov tob txo qis los ntawm cov circuits xws li rectification, filtering thiab voltage regulation.

Kev hloov pauv fais fab siv cov transformer siab rau kev hloov pauv fais fab, uas muaj kev siv hluav taws xob ntau dua thiab lub zog ceev.

Hauv kev xaiv, qhov tso zis siab tshaj plaws ntawm lub zog din rail feem ntau me me, tsuas yog haum rau PLC, sensor, maub los tswj fais fab mov.

Cov khoom siv fais fab hloov pauv tuaj yeem txhawb nqa ntau yam khoom thauj, suav nrog cov khoom siv computer, cov khoom siv sib txuas lus, cov khoom siv automation hauv kev lag luam, thiab lwm yam.

Din rail switching fais fab mov feem ntau siv tau rau hauv cov xwm txheej hauv qab no:

kev siv tshuab hauv tsev, cov txheej txheem tswj hwm hauv tsev, cov txheej txheem tswj kev lag luam, kev siv tshuab hauv Hoobkas, cov khoom siv kho tshuab thiab hluav taws xob, cov txheej txheem tshuaj xyuas lub zeem muag, cov ntawv thov cog qoob loo, cov ntawv thov kev ruaj ntseg.

Muaj ntau daim ntawv thov scenarios, ntawm chav kawm, tseem muaj ntau chav rau kev siv ntau dua ntawm Din rail fais fab mov yav tom ntej.

Yuav tsum xyuam xim dab tsi thaum xaiv lub zog fais fab din rail?

1) Xaiv qhov input voltage specification tsim nyog;

2) Xaiv lub hwj chim kom raug. Yuav kom lub neej ntawm lub hwj chim loj hlob, tus qauv uas muaj ntau dua 30% ntawm lub zog tso zis ntsuas tuaj yeem xaiv tau;

3) Xav txog cov yam ntxwv ntawm lub nra hnyav. Yog tias lub nra hnyav yog lub cev muaj zog, lub teeb lossis lub nra hnyav capacitive, thaum lub zog pib loj, yuav tsum xaiv lub zog tsim nyog kom tsis txhob muaj kev thauj khoom ntau dhau. Yog tias lub nra hnyav yog lub cev muaj zog yuav tsum xav txog kom nres thaum lub zog hluav taws xob raug cuam tshuam;

4) Ntxiv rau qhov xav tau los xav txog qhov kub ntawm qhov chaw ua haujlwm ntawm lub zog fais fab, thiab tsis muaj cov khoom siv txias ntxiv, hauv qhov kub siab ntawm lub voj voog fais fab kom txo cov zis;

5) Xaiv ntau yam haujlwm raws li qhov xav tau ntawm daim ntawv thov:

Kev tiv thaiv kev ua haujlwm: kev tiv thaiv hluav taws xob dhau (OVP), kev tiv thaiv kub dhau (OTP), kev tiv thaiv overload (OLP), thiab lwm yam;

Daim ntawv thov muaj nuj nqi: teeb liab muaj nuj nqi (lub zog ib txwm muaj, lub zog tsis ua haujlwm), kev tswj chaw taws teeb, telemetry, ua haujlwm sib luag;

Nta: Kev kho qhov fais fab (PFC), kev muab hluav taws xob tsis tu ncua (UPS);

6) Xaiv qhov kev ua raws cai thiab daim ntawv pov thawj electromagnetic compatibility (EMC).
