Cov qauv khoom
1. LubAC contactorsiv lub tshuab hluav taws xob los tsav lub voj voog tseem ceeb, thiab kev sib cais thiab kev sib xyaw ua ke ntawm cov ntsiab lus tseem ceeb yog tswj los ntawm lub tshuab hluav taws xob thiab lub kaw lus tiv tauj tseem ceeb.
2. Lub ntsiab lus tseem ceeb ntawm kev sib cuagAC contactorsiv rau kev txuas thiab txiav cov khoom siv fais fab AC, thiab kuj tseem siv tau ua lub voj voog hloov pauv.
3. Lub kaw lus sib cuag ntawmAC contactorfeem ntau yog tsim los ntawm ob lub ntsiab kev sib cuag thiab ob lub koom haum pabcuam uas tau kho rau ntawm lub bracket.
4. Lub AC contactor kauj yog ntsia rau ntawm lub hlau core, thiab muaj cov ntawv insulating thiab windings nyob ib ncig ntawm lub kauj. Cov windings feem ntau yog 300 ~ 350 m ntev.
5. Lub kaw lus sib cuag ntawmAC contactoryog tsim los ntawm cov khoom siv tua hluav taws xob arc, uas feem ntau muab faib ua ob hom: hom cais thiab hom tsis cais. Hom cais suav nrog cov khoom siv tua hluav taws xob rwb thaiv tsev thiab lub chamber tua hluav taws xob hlau dielectric arc, thaum hom tsis cais suav nrog cov roj carbon arc lossis cov khoom siv tua hluav taws xob nqus tsev.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm
Thaum lub AC contactor ua kom lub electromagnetic coil muaj zog, lub electromagnet nyiam lub coil thiab lub coil tam sim no hla dhau lub voj voog thauj khoom los tsim lub electromagnetic torque. Tib lub sijhawm, vim tias lub hlau core muaj lub zog magnetic, lub zog electromagnetic tsim ua rau lub hlau core txav tau txav thiab nqus lub contactor coil. Thaum lub coil tam sim no ploj mus, lub zog magnetic ploj mus, lub caij nplooj ntoos hlav rov qab mus rau nws qhov chaw qub, thiab lub contactor txiav lub voj voog tam sim ntawd.
Thaum lub kauj ntawm AC contactor raug hluav taws xob, nws lub peev xwm muaj feem cuam tshuam nrog qhov tsis kam ntawm lub nra. Qhov tsis kam siab ua rau tam sim no hla dhau tsawg dua thiab siv hluav taws xob tsawg dua. Thaum AC contactor thaum tam sim no tsim los ntawm lub kauj loj dua, yog li ntawd nyob rau hauv lub ntsiab sib cuag tsim ib qho kub.
Cov cua sov tsim tawm hauv lub voj voog yog raws li nram no:
3, Kub tsim los ntawm kev ua ntawm lub ntsiab kev sib cuag
4, Kub tsim los ntawm kev nthuav dav ntawm cov roj hauv lub hau;
5, cua sov tsim los ntawm kev txhuam kho tshuab;
Cov kev tsis sib xws
1, Qhov ntsuas hluav taws xob: AC380V lossis AC380V, 60Hz.
3, Ua haujlwm zaus: 20Hz ~ 40Hz.
4, Qhov kub ua haujlwm siab tshaj plaws ntawm lub kauj: - 25 ℃ ~ + 55 ℃.
5, Lub peev xwm tua hluav taws arc: lub siab arc hauv lub chamber tua hluav taws arc yuav tsum muaj peev xwm ua kom lub sijhawm ntawm ib qho kev sib tsoo yog ntau dua 3ms ntawm 100W, thiab feem ntau siv 30W arc tua hluav taws ntaus ntawv.
6, Qhov voltage poob ntawm tus contactor yuav tsum tsis pub tshaj 2% lossis 5% ntawm qhov voltage rated.
8, Lub sijhawm pib: tsawg dua lossis sib npaug rau 0.1S (rau qhov ntsuas tam sim no ntau dua 30A, lub sijhawm pib yuav tsum tsawg dua 0.045S); rau qhov tam sim no tsawg dua 20A, lub sijhawm pib yuav tsum tsawg dua 0.25S.
10, Qhov kub ua haujlwm tsawg kawg nkaus: ntawm - 25 ℃, tso cai rau lub sijhawm ua haujlwm luv luv ntawm 0 ~ 40 feeb, lub sijhawm ua haujlwm siab tshaj plaws ntawm 20 feeb.
Cov Lus Ceeb Toom
1. Lub zog hluav taws xob siv rau AC contactor yuav tsum ua tau raws li lub zog hluav taws xob uas tau teev tseg los ntawm cov khoom.
2. Ua ntej siv lub AC contactor, xyuas seb nws puas puas lawm, seb cov khoom puas tiav, thiab seb cov terminals puas xoob lossis tawm.
3. Hauv cov cheeb tsam uas lub zog hluav taws xob hloov pauv ntau heev, lub AC contactor yuav tsum tau nruab nrog cov khoom siv them nyiaj sib xws.
4. Thaum lub AC contactor raug wired, tus qauv ntawm lub davhlau ya nyob twg yuav tsum tau kuaj xyuas kom zoo, thiab cov kev ntsuas sib xws yuav tsum tau ua yog tias cov theem lossis cov kev ntsuas pom tias tsis sib xws.
5. Thaum sim cov khoom tshiab, tus AC contactor yuav tsum ua tib zoo xyuas seb qhov voltage ua haujlwm, qhov tam sim no ua haujlwm thiab tus nqi tiv thaiv puas ua tau raws li qhov yuav tsum tau ua.
6. Tej zaum yuav muaj hluav taws xob tawg, hluav taws xob arc thiab lwm yam kev cuam tshuam hluav taws xob muaj zog thaum lub ntsiab ntawm AC contactor tawg. Yog li ntawd, lawv yuav tsum tau kuaj xyuas tsis tu ncua yog tias muaj xwm txheej txaus ntshai.
