Thaum txhim kho cov xaim hluav taws xob lossis kev sib txuas lus hauv hluav taws xob, nws yog ib qho tsim nyog yuav tsum ua cov ntsiab lus nodal ntawm qhov kev hloov ntawm ib lub npav mus rau lwm qhov los yog ceg ntawm txoj kab tseem ceeb coj mus rau cov khoom tshwj xeeb lossis cov khoom siv hluav taws xob. Cov chaw zoo li no yuav tsum ua ntej kom muaj kev nyab xeeb thiab ntseeg siab tiv thaiv cov neeg sib txuas los ntawm kev cuam tshuam ib puag ncig. Rau cov hom phiaj no, cov thawv sib txuas tau tsim.
Dab tsi yog junction boxes
Lub thawv ntim yas (lossis hlau) yog ib lub thawv ntawm puag ncig, square lossis duab plaub, nruab nrog lub qhov rau nkag mus rau cov khoom siv hluav taws xob. Lub luag haujlwm tseem ceeb ntawm cov khoom yog los tiv thaiv cov xaim ntawm cov xov hlau, uas tuaj yeem sib cuam tshuam sab hauv los ntawm kev sib tw, sib tw lossis siv cov khoom siv davhlau ya nyob twg. Cov kev rho tawm tau txais raug xa mus rau txhua qhov kev coj.
Cov thawv sib txuas rau kev teeb tsa sab nraum zoov yog rau pab pawg ntawm cov khoom siv hluav taws xob. Lawv qhov tshwj xeeb qhia tias muaj nyob hauv cov khoom siv li nocov ntsiab lus muaj lub luag haujlwm rau qhov nruj ntawm cov kev sib txuas sab hauv. Yog li, lawv tau nruab nrog gaskets, couplings uas tiv thaiv kom tsis txhob ya raws ntawm cov ntaub ntawv los ntawm cov inlets thiab lub hau.
Scope of application
Qhov chaw uas lub thawv sib txuas tuaj yeem siv tau cuam tshuam txog kev xa hluav taws xob thiab hluav taws xob teeb liab uas tau xa mus siv cov xov hlau. Yog li ntawd, muaj ntau yam ntawm lawv:
- Pa hluav taws xob faib - tsim los nqa tawm cov xaim hluav taws xob xaim hluav taws xob hauv tsev thiab kev lag luam. Cov thawv no kuj tseem siv tau rau tam sim no.
- Xov tooj, khoos phis tawj, rau kev taw qhia - lawv yog bred stranded log tsheb. Lawv feem ntau yog muab cov terminals thiab cov ntaub ntawv pov thawj tamper.
- Cov thawv ntim rau sab nraum zoov teeb tsa rau cov khoom siv hluav taws xob ntau zaus thiab microwave. Nyob rau hauv lawv, nws yog ib qhov ua tau tsis tsuas yog rau desolder nyob ntawm tej, tab sis kuj muaj peev xwm rau nruab me me circuits. Cov ntaub ntawv yuav tsum tau tiv thaiv, thiab cov ntsiab lus qee zaum tau ntim nrog cov dej tsis sib haum yog tias cov cuab yeej ua haujlwm hauv cov av noo siab.
Kev faib lub thawv kab
Cov thawv sab nraum zoov tau muab faib ua ntau pawg.
Khoom siv:
- Polymer - polyethylene, polypropylene, polystyrene case.
- Hlau - ua los ntawm tin lossis aluminium thiab nws cov alloys.
Destination:
- Tsev - rauyug me nyuam hluav taws xob thaiv, qhov twg ib-theem tes hauj lwm siv.
- Industrial - high-strength mini-lub thawv uas peb-theem voltage nyob ntawm tej bred.
- Tshwj xeeb - sab nraum zoov hlws ris lub thawv rau xaim teeb liab cables ntawm mem tes, xov tooj cua zaus thiab microwave technology.
Installation method:
- Qhib hom - xaim khiav tawm sab nraud.
- Hidden type - cov cables muab zais rau hauv strobe.
qib kev nyab xeeb:
- IP44 - lub thawv uas tuaj yeem siv sab nraum zoov hauv qab npog los ntawm cov nag ncaj qha, plua plav, hauv chav nrog qhov chaw ntub dej.
- IP55 - lub thawv uas tuaj yeem tiv taus lub sijhawm luv luv nrog dej thiab tsis txhob cia cov plua plav tawm. Hom khoom faib khoom nrov tshaj plaws.
- IP65 - tsim los rau kev teeb tsa hauv qhov chaw raug huab cua, tsis txhob cia dej los nag thiab plua plav dhau.
- IP67 - tuaj yeem khaws cia rau hauv qhov chaw ntub dej ntev ntev, piv txwv li, hauv av lossis ntawm nws qhov chaw.
- IP68 - tuaj yeem tiv thaiv cov xaim hauv qab dej. Lawv tsim los rau qhov tob tob.
Kev tsim cov thawv sib txuas
Txhua lub thawv hluav taws xob txuas hluav taws xob sib koom ua tib yam tsim qauv, tab sis muaj qee qhov sib txawv hauv kev nthuav dav.
Nto mount thawv suav nrog:
- Square, rectangular lossis round box nrog qhovrau sab thaiv, npog ntsia hlau nkag threaded bushings, DIN rail mounting bushings, thiab qhov rau nto mounting.
- Lub hau nruab nrog lub channel rau sealing roj hmab thiab qhov rau mounting screws rau lub thawv. Ntawm nws qhov chaw sab nrauv, cov kev tsis sib xws ntawm cov khoom feem ntau yog qhia.
- Kab rau kab duct lossis xaim nkag.
- Plaub hau hau.
- Cov pos hniav.
- DIN rail rau txuas cov xov hlau (tsis muaj nyob rau txhua tus qauv).
- khawm kev ruaj ntseg uas txuas nrog lub tswb txhawm rau tiv thaiv kev nkag tsis tau (tsuas yog muaj nyob ntawm cov qauv tshwj xeeb).
Sab nraum zoov mortise-hom thawv txawv ntawm cov lus piav qhia saum toj no uas tsis muaj cov pos hniav thiab qog, vim tias tag nrho saum npoo yog muab zais rau hauv ib txheej ntawm putty, uas, ua kom ya raws, nws tus kheej muab kev tiv thaiv hermetic.
Hauv cov thawv hlau, cov kab hluav taws xob tau ntxig los ntawm cov khoom siv threaded. Lawv ntseeg tau ntau dua tiv thaiv kev sib txuas los ntawm huab cua cuam tshuam. Cov khoom zoo li no tsis tas yuav muaj kev tiv thaiv.
Kev sib txuas ntawm lub thawv sib txuas
Txhawm rau nruab lub thawv xaim, koj yuav xav tau cov cuab yeej hauv qab no:
- Electric laum nrog cuam tshuam ua haujlwm.
- Pliers.
- Slotted and slotted screwdriver.
- Txoj riam nrog cov hniav sib hloov.
khoom ntxiv:
- Ib daim kab xev.
- Screw terminals hluav taws xob.
- Txhobkhoom siv (tus kheej tapping screws, yas dowels).
Cov txheej txheem kev teeb tsa rau lub thawv thaiv sab nraud yog raws li hauv qab no:
- Qhov yog drilled ntawm qhov chaw teeb tsa rau txuas lub thawv rau lub dav hlau, dowels tau tsav hauv.
- Qhov raug txiav hauv caj pas nrog rab riam rau txoj kab uas xav tau.
- Cov khoom siv hluav taws xob tau ntsia hlau sab hauv rau tus lej xav tau.
- Lub thawv yog txuas rau ntawm phab ntsa nrog tus kheej tapping screws, ntsia hlau rau hauv dowels.
- Cov hlau raug muab tso rau hauv lub qhov hauv cov qog.
- Smooth kawg ntawm cov xov hlau los ntawm cov khoom siv insulating thiab tshem tawm cov txheej oxidation, yog tias tam sim no.
- Sib dhos lub voj voog hauv lub thawv sib txuas, kho cov xov hlau hauv qhov chaw tsim nyog.
- Kaw lub hau ntawm lub thawv, kho nws nrog threaded screws.
txiaj ntsig ntawm kev siv lub thawv sib txuas
Qhov yooj yim ntawm kev siv lub thawv ntim khoom tau tsim tau zoo:
- Cov khoom yog tsim rau cov kab sib txawv.
- Muab kev tiv thaiv kev tiv thaiv siab nrog kev xaiv zoo ntawm cov khoom siv.
- Tsis muaj teeb meem ntawm mount rooj plaub thiab txuas cov xov hlau.
- Ntau yam ntawm cov duab thiab kho kom zoo nkauj, xws li ntoo saib sab nraum zoov hleb.
- Muaj peev xwm nkag mus rau kev sib txuas lus thiab rov txuas dua.
- Design durability.
Zaj lus
Txawm hais tias qhov yooj yim ntawm kev teeb tsa ntawm cov thawv sib txuas, nws tseem ceeb heev kom nco ntsoov tias tsuas yog cov kws tshaj lij hluav taws xob thiab cov kws tsim hluav taws xob tau nkag mus rau hom kev ua ub no thaum nws los txog rau kev xaim hluav taws xob!
