Qhov sib txawv ntawm AC Contactors thiab DC Contactors

Txawm tiasAC thiab DC contactorsqhia tib lub luag haujlwm tseem ceeb- nquag sib txuas thiab txiav tawm cov kab hluav taws xob loj -lawv sib txawv hauv lawv cov qauv kev ua haujlwm, qauv, thiab kev siv.

Lub ntsiab cai

Qhov tseem ceeb sib txawv ntawmAC thiab DC contactorsnyob rau hauv lawv cov arc- tua tshuab thiab cov qauv tseem ceeb.

AC contactors siv xoom-hloov tus yam ntxwv ntawm kev hloov tam sim no, siv ib daim phiaj-hom arc- tua hluav taws kom tua cov arc zoo. Lawv cov cores yog ua los ntawm cov ntawv laminated silicon steel thiab nruab nrog luv luv - lub voj voog hluav taws xob kom tshem tawm kev co thiab suab nrov uas tsim los ntawm AC electromagnetic rog.

DC contactors, vim tias lawv qhov tam sim no tsis muaj xoom- hla qhov taw tes, yuav tsum tso siab rau lub zog sib nqus sib nqus sib nqus-txoj kev tua kom yuam kom ntev thiab txias lub arc. Lawv cov cores yog ib qho, ib qho qauv, thiab vim tias DC tam sim no tsim cov hlau nplaum tas li, luv luv - cov nplhaib hluav taws xob tsis tsim nyog.

Cov kev sib txawv tseem ceeb no tshwm sim los ntawm qhov sib txawv uas yuav tsum tau muab tso rau hauv lub tshuab electromagnetic thiab arc -kev muaj peev xwm tua hluav taws xob los ntawm kev hloov pauv ntawm AC thiab qhov xwm txheej tas li ntawm DC tam sim no.

Sib txawv Analysis
1. Core Structure:

AC contactors yog ua los ntawm laminated silicon steel los xij, thiab luv luv - cov nplhaib hluav taws xob tau teeb tsa rau ntawm lub ntsej muag kawg ntawm cov tub ntxhais.

DC contactors yog tsim los ntawm ib qho ntawm cov hlau me me lossis engineering hlau ntshiab, nrog U- zoo li tus tub ntxhais thiab tsis muaj luv - lub nplhaib hluav taws xob.

2. Arc Extinguishing System:

Arc extinguishing yog ib qho yooj yim rau AC contactors. Nws feem ntau siv phaj arc extinguishing los yog sib nqus blowout arc extinguishing. Qhov no yog vim AC tam sim no hla xoom 100 zaug ib ob, thiab cov arc yooj yim tua nws tus kheej ntawm cov ntsiab lus no.

Arc extinguishing yog qhov nyuaj rau DC contactors. Sib nqus blowout arc extinguishing feem ntau yog siv. Qhov no yog vim DC tam sim no tsis hla xoom 1, ua rau arc ruaj khov thiab nyuaj rau tua.

3. Coil Parameters:

AC contactor coils muaj tsawg dua, tuab hlau txoj kab uas hla, thiab qis kuj. Qhov no yog vim qhov impedance ntawm AC coil feem ntau yog nyob ntawm inductive reactance; Kev tiv thaiv DC ntau dhau yuav ua rau muaj cua sov heev.

DC contactor coils muaj ntau lem, thinner hlau txoj kab uas hla, thiab siab dua. Qhov no yog vim qhov impedance ntawm DC coil yog qhov tsis muaj zog, yuav tsum muaj kev tiv thaiv loj dua los txwv qhov tam sim no.

4. Kev khiav hauj lwm zaus:

AC contactors tuaj yeem ua haujlwm ntawm ntau zaus, ua rau lawv haum rau cov ntawv thov uas yuav tsum tau pib ntau zaus - nres cycles.

DC contactors feem ntau ua haujlwm ntawm qhov qis dua vim tias DC arcs nyuaj rau tua thiab lawv cov txheej txheem tawg yuav siv sij hawm ntev dua.

5. Daim ntawv thov:

AC Contactors: Feem ntau siv los tswj AC loads xws li AC motors, hluav taws xob cua sov, thiab teeb pom kev zoo. Cov no yog cov contactors feem ntau hauv kev lag luam.

DC Contactors: Feem ntau yog siv los tswj DC loads xws li DC motors, roj teeb them thiab tawm Circuit Court, thiab DC fais fab faib tshuab. Feem ntau pom nyob rau hauv DC ib puag ncig xws li hluav taws xob locomotives, subways, photovoltaic zog tsim tshuab, thiab hluav taws xob tsheb.
