Hauv kev lag luam hluav taws xob engineering, kev tiv thaiv cov khoom siv thiab cov tshuab yog qhov tseem ceeb tshaj plaws. Qhov no yog qhov chaw AC contactors thiab PLC tswj cov txee tuaj rau hauv kev ua si, lawv yog cov khoom tseem ceeb hauv kev tiv thaiv ua ke. Cia peb ua tib zoo saib xyuas qhov tseem ceeb ntawm cov khoom siv no thiab seb lawv pab ua kom muaj kev nyab xeeb thiab ua haujlwm ntawm koj lub tshuab hluav taws xob.
AC contactors yog qhov tseem ceeb rau kev tswj cov dej ntws ntawm hluav taws xob hauv AC circuits. Lawv ua raws li lub zog hloov hluav taws xob, ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm cov khoom siv hluav taws xob. Hauv kev tiv thaiv kev sib xyaw ua ke, AC contactors ua lub luag haujlwm tseem ceeb hauv kev cais cov khoom siv tsis raug ntawm lub zog hluav taws xob, tiv thaiv kev puas tsuaj, thiab ua kom cov neeg ua haujlwm nyab xeeb.
PLC (Programmable Logic Controller) tswj cov khoom, ntawm qhov tod tes, yog ib feem tseem ceeb ntawm ntau yam txheej txheem automation thiab tswj hauv hluav taws xob. Lawv tau programmed los saib xyuas thiab tswj kev ua haujlwm ntawm cov cuab yeej siv, kom ntseeg tau tias txhua yam ua haujlwm nyob rau hauv qhov tsis zoo. Nyob rau hauv thaj tsam ntawm kev tiv thaiv kev sib txuas, PLC tswj cov txee muab cov kev txawj ntse uas xav tau los txheeb xyuas cov kev tsis sib haum xeeb thiab ua rau muaj kev tiv thaiv los tiv thaiv kev puas tsuaj lossis kev puas tsuaj.
Thaum cov khoom sib xyaw ua ke rau hauv kev tiv thaiv kev sib txuas, lawv tsim muaj lub zog tiv thaiv kev tiv thaiv rau koj lub cev hluav taws xob. Lub AC contactor ua raws li lub cev tsis muaj zog, txiav tawm lub zog thaum muaj kev ua txhaum, thaum lub PLC tswj txee ua haujlwm raws li lub hlwb, tsis tu ncua saib xyuas thiab tshuaj xyuas lub kaw lus rau txhua qhov txawv txav.
Tsis tas li ntawd, kev sib koom ua ke ntawm cov khoom no tso cai rau kev sib koom ua ke tsis sib haum xeeb thaum hais txog kev pheej hmoo. Piv txwv li, yog tias pom tias muaj overload lossis luv Circuit Court, PLC tswj txee tuaj yeem xa cov teeb liab mus rau AC contactor kom tshem tawm cov khoom siv cuam tshuam, tiv thaiv kev puas tsuaj ntxiv thiab ua kom muaj kev nyab xeeb.
Txhawm rau ua kom tiav, AC contactor thiab PLC tswj txee yog qhov tseem ceeb hauv kev tiv thaiv hluav taws xob ua ke. Lawv lub peev xwm los cais cov kev ua txhaum cai, ua kom muaj kev tiv thaiv zoo, thiab sib koom ua ke cov lus teb rau cov kev pheej hmoo yog qhov tseem ceeb los ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob. Los ntawm kev nkag siab thiab paub txog qhov tseem ceeb ntawm cov khoom no, cov kws tsim khoom thiab cov kws tshaj lij tuaj yeem tiv thaiv cov tshuab hluav taws xob zoo los ntawm kev phom sij, thaum kawg pab tsim kom muaj kev nyab xeeb, ua haujlwm tau zoo dua.
