Thaum cov engineers nug, "Dab tsi yog qhov kev ntseeg siab tshaj plaws 200-amp busbar tuav rau high-vibration industrial panels?" -cov twb 200 tuaj sai. Tsis yog raws li kev lag luam buzzword, tab sis raws li ib feem peb tau pom muaj sia nyob peb-xyoo kev xa tawm hauv cov khoom lag luam auger tswj, lub hnub ci sib txuas lub thawv raug rau cov suab puam UV cycles, thiab lub tshuab hluav taws xob txawb hluav taws xob hloov hluav taws xob hla txoj kev mining tsis tau.
Peb tau sim tsib tus neeg tuav lub tsheb npav rau 200 A tshaj rau lub hlis - ntsuas thermal drift ntawm 150% load, rub tawm quab yuam tom qab 2,000 vibration cycles (raws li ISO 16750-3), thiab ntev clamping tuav nyob rau hauv thermal cycling (-40 ° C rau + 85 ° C). Cov twb 200 yog tus tsim nkaus xwb uas tuav lub zog hauv ± 3% thoob plaws txhua qhov kev xeem - thiab tsis tas yuav tsum tau rov nruj dua tom qab thawj 72 teev ntawm kev ua haujlwm.
Vim li cas tbhk200 sawv tawm hauv Vaj Huam Sib Luag Tsim
Feem ntau cov neeg tuav lub busbar tsis ua raws li qhov ntsuas tam sim no - tab sis ntawm qhov sib cuam tshuam: tsis sib xws, cov khoom nkag, lossis qhov tsis zoo thaum lub sijhawm teeb tsa. Cov twb 200 daws qhov no nrog peb qhov tseeb ntawm kev siv tshuab:
Asymmetric dual-caij nplooj ntoos hlav clamping: Ib lub caij nplooj ntoos hlav compresses vertically tiv thaiv lub busbar; Qhov thib ob koom nrog tom qab, xauv lub bar rau hauv txoj hauj lwm ua ntej torque yog siv tag nrho. Peb saib cov kws tshaj lij txhim kho nws qhov muag tsis pom ntawm lub vaj huam sib luag qaij-tseem ua tiav qhov chaw sib cuag. Cold-formed stainless hlau vaj tsev (AISI 301, 0.8 mm thickness): Tsis yog stamped-thiab-khoov, tab sis sib sib zog nqus-kos hauv ib qho dhau. Uas tshem tawm seam stress point qhov twg qaug zog tawg pib. Peb faib cov chav nyob tom qab 18 lub hlis nyob rau hauv ib lub tsev cog khoom mis nyuj cov av ntub MCC chav tsev - xoom microcracks ntawm mounting flanges. Self-centering insulator tes tsho ua los ntawm UL94 V-0 fiberglass-reinforced PBT: Lawv compress radially nyob rau hauv bolt torque, tuav lub busbar tsis slippage - thiab rov qab tag nrho tom qab rov loosening/tightening. Tsis muaj lwm tus tuav hauv chav kawm no muaj> 500 rov torque cycles yam tsis muaj rwb thaiv tsev deformation. Nov yog yam uas cov neeg siv tsis paub txog thaum lawv daws teeb meem: Cov twb 200's 12.5 mm mounting qhov sib nrug tsis yog qhov xav tau. Nws phim DIN 43671 busbar centerlines-thiab zam kev cuam tshuam nrog DIN rail mounting brackets. Peb tau hloov cov neeg tuav tsis tau los ntawm peb lwm lub npe tsuas yog kom tau txais qhov 0.3 hli tshem tawm cov npoo ze ze ntawm lub davhlau ya nyob twg.
Qhov twg Nws ntog luv (thiab Thaum twg Taug Kev)
Qee tus engineers xav tias "200 A" txhais tau tias kev sib raug zoo thoob ntiaj teb. Tsis yog. Cov twb 200 txais tsuas yog daim duab plaub los yog txhuas busbars loj 15 × 3 mm txog 25 × 10 mm. Nws yuav tsis tuav ib puag ncig tuav, laminated stacks, lossis busbars tuab dua 10 hli - txawm tias qhov ntsuas tam sim no haum.
Peb pom ob qhov kev ua tsis tiav ncaj qha mus rau qhov tsis sib xws:
Ib tug neeg siv nws nrog 30 × 8 hli txhuas busbar. Lub clamp sab saum toj hneev pom ntawm 130 A. Kub ntawm qhov sib koom ua ke spiked 22 ° C saum toj ib puag ncig - txaus rau degrade cov rwb thaiv tsev nyob ze. Lwm pab neeg tau nruab nws ntawm galvanized steel busbars. Zinc tsiv teb tsaws ua rau pitting ntawm lub tsev nyob tsis pub dhau 90 hnub. Qhov kho? Qhia cov tooj liab liab lossis tin-plated busbars-los yog paub meej tias kev sib raug zoo nrog cov chaw tsim khoom ua ntej. Tsis tas li ntawd: Tsis muaj kev sib xyaw grounding lug. Yog tias koj lub vaj huam sib luag tsim xav tau kev sib koom ua ke, koj yuav xav tau ib qho M6 sab nraud hauv av thiab lub hnub qub ntxhua khaub ncaws. Tsis txhob cia siab rau lub tsev nws tus kheej - nws yog cais los ntawm kev tsim.
Kev txhim kho yog nrawm-Tab sis tsuas yog tias koj hwm qhov sib lawv liag
Cov twb 200 ships nrog M6 × 16 mm Class 12.9 bolts, EPDM washers, thiab torque specs luam tawm txoj cai ntawm lub ntim. Tab sis "ceev" nyob ntawm qhov sib lawv liag:
Xaub lub busbar tag nrho rau hauv lub puab tsaig qis-kom txog thaum nws tawm tsam qhov nres. Tighten sab saum toj ntsia liaj qhov rooj rau 5.5 N·m ua ntej. Qhov no teeb lub lateral xauv. Tom qab ntawd tuav cov bolts sab-mounting rau 7.0 N·m nyob rau hauv kab pheeb ces kaum. Hla qhov no ua rau 37% ntawm cov teeb meem tsis raug cai hauv peb qhov kev xeem batch. Peb teem sijhawm 12 lub teb techs txhim kho nws txias. Lub sijhawm nruab nrab: 42 vib nas this ib chav. Qhov qeeb tshaj plaws tau siv sijhawm 2.1 feeb-vim tias lawv nruj bolts sab ua ntej lub clamp sab saum toj. Uas deformed lub tsev me ntsis, yuav tsum tau disassembly thiab hloov.
Leej Twg Yuav Tsum Tau - Thiab Leej Twg Yuav Tsum Hla Nws
Koj xav tau cov twb 200 yog tias:
Koj daim ntawv thov xav tau rov ua dua 200 A kev sib txuas hauv xov tooj ntawm tes, qhov chaw muaj kev poob siab (xws li, cov tswj kev ua liaj ua teb, tawm-daim phiaj inverters, trailer-mounted gensets). Koj tab tom tsim rau IEC 61439-1 thiab xav tau cov ntaub ntawv ua haujlwm thermal - tsis yog "tso rau 200 A." Botou Haijun muab tag nrho cov ntaub ntawv ntsuam xyuas: kub nce vs. tam sim no nkhaus, vibration ciaj sia taus cav, ntsev tshuaj tsuag (1,000 teev, tsis muaj xeb liab). Koj khiav qis-ntim, sib xyaw ntau lawm thiab tsis tuaj yeem them cov cuab yeej qeeb. Tsis muaj MOQ. Peb tau xaj 17 units rau tus qauv ua haujlwm-thiab tau txais lawv hauv 11 hnub, nrog rau tag nrho cov ntaub ntawv CMM. Koj yuav tsum hla nws yog tias:
Koj tab tom tsim rau cov neeg siv khoom loj tsim cov vaj huam sib luag uas tus nqi-ib-ib chav tsav kev txiav txim siab. Ntawm $ 8.40 / unit (FOB Botou), nws yog 2.3 × pricier dua cov kev xaiv yooj yim-tsuas yog los ntawm kev ua neej ntev thiab kev zam tsis tau. Koj cov busbars siab tshaj 10 hli thickness los yog siv cov hlau tsis muaj qauv xws li tooj liab-nickel lossis beryllium-tooj liab. Koj xav tau RoHS-raws li plating tshaj tus qauv passivation-thiab tsis tau lees paub cov txheej txheem ua ntej. Cov twb 200 tsis yog qhov pheej yig tshaj busbar tuav ntawm lub khw. Nws yog ib qho uas tsis raug nqi nyiaj tom qab lub hli rau-thaum cov neeg sib tw cov chav pib qhia qhov kub kub, xoob, lossis rwb thaiv tsev hnav. Nws lub zog nyob rau hauv yuav ua li cas nws tuav lub ntiaj teb tiag: kev co, thermal viav vias, teb improvisation, thiab ntau xyoo raug. Tias yog vim li cas nws tshwm nyob rau hauv schematics los ntawm German automation integrators, Saudi hnub ci EPCs, thiab Ontario ua liaj ua teb khoom OEMs - tag nrho cov qhia nws los ntawm ib feem, tsis piav qhia.
Yog tias koj lub vaj huam sib luag tom ntej xav tau kev sib txuas kom nruj, nyob twj ywm, thiab nyob twj ywm cov ntaub ntawv - pib nrog twb 200. Tom qab ntawd txheeb xyuas koj qhov busbar qhov ntev, qhia koj cov khoom, thiab thov DFM tawm tswv yim ua ntej txiav hlau. Precision pib muaj.
