Cov ntsiab lus ntawm cov khoom siv hluav taws xob
Nov 20, 2024|
Cov khoom siv hluav taws xob yog cov khoom siv yooj yim uas tsim cov tshuab hluav taws xob thiab cov khoom siv hluav taws xob. Lawv ua lub luag haujlwm sib txawv hauv circuits thiab ua haujlwm ua ke kom ua tiav ntau yam hluav taws xob ua haujlwm. Cov hauv qab no yog qee yam khoom siv hluav taws xob thiab lawv cov haujlwm yooj yim thiab cov yam ntxwv:
Circuit Breaker: Lub Circuit Court breaker (QF) yog lub tshuab hluav taws xob tsis siv neeg hloov hluav taws xob uas tuaj yeem ua haujlwm manually thiab tuaj yeem txiav tawm Circuit Court los tiv thaiv cov kab hluav taws xob thiab cov khoom siv los ntawm kev ua txhaum xws li overload, luv Circuit Court lossis undervoltage.
Contactor: Ib lub contactor (KM) muaj ib lub tshuab electromagnetic thiab kev sib cuag, uas yog siv los txuas thiab disconnect circuits thiab feem ntau yog siv los tswj cov khoom hluav taws xob xws li motors. Lub contactor muaj kev tiv thaiv qis qis thiab xoom hluav taws xob tiv thaiv kev ua haujlwm, uas tsim nyog rau kev ua haujlwm nquag thiab kev tswj chaw taws teeb.
Thermal relay: Ib lub thermal relay (FR) siv lub hauv paus ntsiab lus ntawm thermal nyhuv generated los ntawm tam sim no dhau los ntawm lub caij los ua inverse time action, thiab mas yog siv rau overload tiv thaiv.
Intermediate relay: Ib qho nruab nrab relay (KA) yog siv los hloov cov teeb liab tawm tswv yim rau hauv ntau lub teeb liab tawm lossis nthuav tawm cov teeb liab, thiab feem ntau siv los nthuav cov xov tooj lossis lub peev xwm ntawm kev sib cuag.
Khawm: Khawm (SB) yog siv los tswj lub hauv thiab tawm ntawm lub voj voog. Cov xim muaj xws li liab (nres), ntsuab (pib), dub (alternating action), thiab lwm yam, uas yog siv los qhia txog kev ua haujlwm ntawm cov khoom siv.
Qhov taw qhia lub teeb: Lub teeb qhia tau siv los qhia txog kev khiav lossis nres ntawm cov khoom siv thiab saib xyuas seb lub hwj huam mov puas zoo li qub. Nws feem ntau muaj xim liab, ntsuab, xiav thiab lwm yam xim.
Fuse: Lub fuse yog ib qho khoom siv tiv thaiv kev nyab xeeb. Thaum qhov tam sim no tshaj qhov nqi teev, nws heats li yaj lub fuse, yog li disconnecting Circuit Court. Nws yog dav siv nyob rau hauv siab thiab tsis tshua muaj hluav taws xob hluav taws xob faib tshuab thiab khoom siv hluav taws xob.
Lub sij hawm relay: Tom qab tau txais lub teeb liab, lub sij hawm relay ua rau cov zis tom qab lub sij hawm ncua sij hawm, thiab feem ntau yog siv rau lub sij hawm tswj.
Kev hloov pauv mus txawv tebchaws: Kev hloov pauv mus txawv tebchaws (tseem hu ua txoj haujlwm hloov) siv qhov kev txiav txim ntawm cov khoom txav mus los tswj lub hauv thiab tawm ntawm lub voj voog. Nws feem ntau yog siv los txwv txoj haujlwm lossis kev mus los ntawm kev siv tshuab.
Hloov pauv hloov: Hloov hloov pauv yog siv los hloov ntau lub voj voog. Cov kev sib cuag ntawm lub rotating ncej yog txuas los yog disconnected nrog zoo li qub kev sib cuag nyob rau hauv lem mus cuag circuit switching.
Cov khoom siv hluav taws xob no ua lub luag haujlwm tseem ceeb hauv cov tshuab hluav taws xob thiab cov khoom siv hluav taws xob, thiab kev nkag siab txog lawv cov haujlwm yooj yim thiab cov yam ntxwv yog qhov tseem ceeb rau kev tsim hluav taws xob thiab kev saib xyuas.
