Sib txuas lus txoj cai ntawm AC contactors.
Thaum lub kauj yog ntsaws rau hauv, cov tub ntxhais hlau ntawm lub tshuab hluav taws xob zoo li qub ua rau lub zog tam sim no adsorption zom thiab nqus cov tub ntxhais hlau ntawm lub dynamic transformer.Vim hais tias qhov kev sib cuag ntawm qhov system software txuas nrog cov hloov pauv hloov pauv hlau tub ntxhais, qhov hloov pauv hloov pauv hlau tseem ceeb thawb peb lub ntsiab lus txav mus rau tib lub sijhawm, qhov kev sib cuag tseem ceeb kaw, pab qhov kev sib txuas ib txwm kaw kom tawg, pab lub kaw lus ib txwm kaw. kaw, thiab txuas lub zog hloov hluav taws xob.
Thaum lub coil yog powered, lub adsorption quab yuam txo, thiab qhov txuas ntawm cov hlau tseem ceeb ntawm lub transformer txav yog sib cais los ntawm lub recoil quab yuam ntawm lub caij nplooj ntoos hlav torsion, tawg lub ntsiab Circuit Court breaker, thiab cov koom haum feem ntau kaw kev sib cuag nrog lub Lub tes tsho tseem ceeb tiv tauj tau raug kaw los pab qhov kev sib cuag kaw.Lub kaw lus kaw tau tawg, thiab cov khoom siv hluav taws xob hloov pauv tau raug txiav tawm.
Kev sib txuas lus contactor tsuas yog siv los sib txuas lus txoj kev sib txuas lus.Yog tias AC contactor yuav tsum txuas nrog DC, qhov xaus yuav tsum yog tias txoj kev thiab txawm tias cov tshuab thiab cov cuab yeej raug puas tsuaj loj.
Ib qho tseem ceeb ntawm kev sib txuas lus contactor.
(1) Electromagnetic induction system software, suav nrog kev nyiam cov coils, txav transformer hlau cores thiab static hlau cores;
(2) Lub Circuit Court breaker system software muaj xws li peb pawg ntawm lub ntsiab Circuit Court breakers thiab ib mus rau ob pawg ntawm on thiab off.Qhov ib txwm kaw lub koom haum Circuit Court breaker txuas nrog cov tub ntxhais hlau ntawm lub transformer txav;
(3) Cov khoom siv sib nqus tshuab, feem ntau muaj peev xwm loj AC contactors tau nruab nrog cov khoom siv sib nqus tshuab, uas yooj yim rau kev sib cais hluav taws xob sai thiab tiv thaiv lub ntsiab hluav taws xob los ntawm kev kub hnyiab;
(4) Rwb thaiv tsev txheej casing thiab accessories, ntau yam springs, kis mechanisms, luv-circuit txhaum rings, terminals, thiab lwm yam.
Sib txuas lus txoj kev xaim ntawm AC contactor.
Muaj lub logo ntawm tus contactor (raws li kev muaj tiag)
1L3L5L, uas sib haum rau 2T4T6T, yog qhov tseem ceeb interface.
Cov coils sib xws muaj cov terminals A1A2.
Cov neeg pabcuam pabcuam tuaj yeem sib phim.
13.14 qhia txog kev sib tiv tauj ntawm tus contactor, TSIS qhia rau thiab tawm, uas yog, 13.14 yog txiav tawm yam tsis tau ntsaws rau hauv, thiab 13.14 raug tua tom qab ntsaws rau hauv nws tus kheej-locking (thiab txuas nrog lub khawm khiav) muab tso rau hauv ib feem. ntawm kev tswj lub voj kom ua tiav lub hom phiaj ntawm kev ua haujlwm tsis tu ncua.
Kev sib txuas lus AC contactor thaiv daim duab.
Kho lub cev muaj zog reversible lag luam tswj voj.
1. Tshawb xyuas seb qhov kev sib txuas ntawm lub hauv paus tseem ceeb puas raug.Txhawm rau kom ntseeg tau tias ob lub contactors tuaj yeem hloov pauv qhov nruab nrab nyob ntawm lub cev muaj zog thaum lawv txav mus los, cov kab hluav taws xob sab nraud ntawm tus contactor yuav tsum zoo ib yam thiab kho nyob rau hauv qhov qis ntawm lub contactor.
2. Tom qab kuaj xyuas tias cov xaim hluav taws xob yog lawm, yuav tsum tau ua qhov kev sim plug-in.Txhawm rau kom tsis txhob raug mob, tshem tawm cov kab hluav taws xob ua ntej.Npaj rau tej yam kev txhaum;
1. Tsis muaj kev ua haujlwm;ib qho ntawm cov laj thawj yog los xyuas seb qhov kev tuav pov hwm kev lag luam FU puas yog luv luv, seb FR connector ntawm thermal relay siv tsis raug lossis muaj kev sib cuag tsis zoo, thiab seb qhov sib txuas ib txwm kaw ntawm SB1 khawm tsis zoo.Qhov thib ob qhov tseem ceeb yog qhov tsis raug thaiv ntawm qhov tseem ceeb ntawm tus kheej-locking interlock.
2. Thaum lub sijhawm ua haujlwm, tus contactor tsis nqus;Qhov no yog vim hais tias ib txwm kaw kev sib cuag ntawm tus contactor tsis raug txuas nrog tus kheej-locking interlock, thiab tus kheej-locking thiab interlocking kov yog nws tus kheej-locking.Hauv kev ua haujlwm, qhov ib txwm kaw qhov chaw yog lub tshuab nqus hluav taws xob ntawm lub contactor coil.Tom qab lub contactor coil yog powered tawm, lub contactor coil yog de-energized thiab tso tawm, ib txwm kaw contactor raug tso tawm, lub contactor yog sucked nyob rau hauv dua, thiab lub contactor raug txiav tawm dua.Yog li, tus contactor tsis yooj yim nqus hauv.
3. Tus kheej-locking contactor tsis tuaj yeem raug txiav.Qhov no yog vim qhov tsis raug ntawm kev sib txuas ntawm tus kheej-locking kev sib cuag thiab rov qab ua haujlwm ntawm lub cev muaj zog.Txhawm rau kom lub cev muaj zog tig mus rau pem hauv ntej thiab thim rov qab, ob lub contactors KM1.KM2 lub cev muaj zog peb Lub zog hluav taws xob nruab nrab yog cov xaim nyob, tab sis ob lub contactors tsis tuaj yeem zom thiab nqus tau.Yog tias zom thiab nqus tau tib lub sijhawm, nws yuav ua rau lub zog hluav taws xob luv luv ntawm kev nyab xeeb kev nyab xeeb.Txhawm rau kom tsis txhob muaj teeb meem kev nyab xeeb, lub zog hluav taws xob hluav taws xob yuav tsum siv qhov kev sib txuas ntawm tus kheej txhim khu kev qha.
Txoj kev anatomy zoo li no:
1. Khiav ntawm qhov zoo:
1. Tshem tawm cov pa hluav taws xob hloov QF thiab txuas peb-theem fais fab mov.
2. Nias thiab tuav lub khawm khiav mus rau pem hauv ntej SB3, KM1 yog ntsaws rau hauv, rub thiab kaw nws tus kheej, thiab lub ntsiab Circuit Court breaker kaw thiab kaw kom txuas lub cev muaj zog.Lub sijhawm no, cov xaim nruab nrab ntawm lub cev muaj zog yog L1.L2.L3, uas yog, nws ua haujlwm hauv qhov zoo.
2. Khiav ntawm qhov sib txawv:
1. Tshem tawm cov pa hluav taws xob hloov QF thiab txuas peb-theem fais fab mov.
2. Nias thiab tuav lub lag luam khawm SB2 nyob rau hauv qhov kev taw qhia, KM2 yog nws tus kheej-locking raws li lub koom haum pab, feem ntau tua lub ntsiab tiv tauj, thiab hloov lub nruab nrab hlau thiab nyob hlau ntawm peb-theem fais fab mov ntawm lub cev muaj zog. .Lub sijhawm no, xoom kab ntawm lub cev muaj zog yog L3.L2.L1, uas yog, nws ua haujlwm nyob rau hauv qhov sib txawv.
3. Tus kheej-locking thiab interlocking theem: Nws muaj qhov txwv tsis pub muaj nuj nqi thiab muaj kev ruaj ntseg lav cuam tshuam hauv cov kab xa khoom.
1. Contactor self-locking and interlocking: KM1 coil control loop is connected in series with the KM2 nquag kaw auxiliary contact, thiab KM2 coil loop is connected in series with the KM1 nquag kaw kev sib cuag.Thaum cov kev sib hloov mus rau pem hauv ntej contactor KM1 kauj yog ntsaws rau hauv, KM1 pab qhov kev sib txuas ib txwm kaw kom txiav tawm KM2 coil tswj Circuit Court.Yog tias KM1 ntsaws rau hauv thiab rub tawm, KM2 yuav tsum xub tua lub hwj chim thiab tso nws los pab hauv kev ntsuas ntawm cov kev sib txuas uas ib txwm kaw kom tsis txhob muaj ob lub xim luv-circuit ua txhaum los ntawm KM1 thiab KM2 raug rub rau tib lub sijhawm. .Txoj kev no yog hu ua tus kheej-locking thiab interlocking theem.
2. khawm nws tus kheej-locking thiab interlocking: qhov zoo thiab qhov tsis zoo ntawm qhov kev ua haujlwm tiag tiag ntawm lub khawm tswj tau xa mus rau lub voj voog tswj rau lub hwj huam mov Circuit Court.Cov nyees khawm SB2.SB3 muaj ib khub ntawm ib txwm kaw cov ntsiab lus thiab ib khub ntawm ib txwm kaw cov neeg sib cuag, uas feem ntau txuas nrog KM1.KM2 coil fais fab Circuit Court.
Piv txwv li, ib txwm kaw qhov taw tes ntawm lub pob SB2 txuas nrog lub kauj ntawm tus contactor KM2, thiab qhov kev sib txuas ib txwm kaw tau txuas nrog lub zog hluav taws xob ntawm lub kauj ntawm tus contactor KM1.Lub kaw lus ib txwm kaw ntawm lub pob SB3 txuas nrog lub kauj ntawm tus contactor KM1, thiab qhov kev sib txuas ib txwm kaw tau txuas nrog lub zog hluav taws xob ntawm KM2 kauj.Txoj kev ntawd, thaum SB2 tuav cia, tsuas yog tus contactor KM2 kauj tuaj yeem ntsaws rau hauv, thiab KM1 tua lub zog.Thaum SB3 nias, tsuas yog tus contactor KM1 kauj tuaj yeem ntsaws rau hauv, thiab KM2 raug kaw.Yog tias SB2 thiab SB3 tuav tib lub sijhawm, ob lub contactor coils tsis tuaj yeem ntsaws rau hauv.
4. Tom qab lub cev muaj zog khiav mus rau pem hauv ntej (los yog rov qab kev taw qhia), nws tsis tas yuav tsum nias lub khawm nres kom txiav lub cev muaj zog, tab sis nias lub pob rov qab (lossis rau pem hauv ntej) ua haujlwm khawm tib lub sijhawm kom lub cev muaj zog. khiav nyob rau hauv txoj kev rov qab.
5. Kev tiv thaiv overvoltage ntawm lub cev muaj zog yog ua los ntawm thermal relay FR.
