Tshiab Zog Contactor Part

Peb lub tuam txhab tsom mus rau kev tshawb fawb, kev tsim kho, thiab tsim cov tshiab Zog Contactor Parts kev daws teeb meem:HVDC Metalized Ceramic, HVDC Copper Tsis Siv Neeg Version Txhaj Moulding Cheebtsam; HVDC Copper Exhaust Pipe & Armature Cover Resistance Brazing Cheebtsam; thiab HVDC Arc Extinguishing Chamber Parts.Cov Khoom Siv Hluav Taws Xob Tshiab no ua tau raws li qhov xav tau ntawm ntau qhov chaw, xws li lub zog, lub zog tshiab, thiab cov khoom siv ua haujlwm.

Lub zog tshiab siab -voltage DC contactors feem ntau yog tsim los ntawm cov hauv qab no:

1. Tsiv Sib cuag
Ua los ntawm tooj liab stamping, nrog cov nyiaj alloy sib cuag welded rau saum npoo kom ntseeg tau zoo heev conductivity thiab arc kuj.

2. Kev tiv tauj ruaj khov
Machined los ntawm tooj liab, nrog ib tug venting qhov qauv, thiab txuas nrog ceramic metallization txheej los ntawm lub tshuab nqus tsev brazing.

3. Metallized Ceramic
Ua los ntawm siab -purity alumina ceramic (Al₂O₃ Ntau dua lossis sib npaug li 95%) kom ua tiav cov rwb thaiv tsev siab tiv taus hluav taws xob thiab airtight sealing.

4. Hluav taws xob Pure Iron Armature & Yoke
Precision stamping, siab sib nqus permeability, thiab qis hysteresis poob, kom ntseeg tau ceev rub-hauv thiab tso tawm kev ua haujlwm.
5. Arc Chamber
Cov qauv sab hauv yog qhov tseeb thiab laser vuam yog siv los ua ke los xyuas kom meej tias cov arc raug tua sai, nyab xeeb, thiab ntseeg tau.
6. Coil Assembly
Tsawg- fais fab coil tsim siv rau hauv tus account lub zog efficiency thiab suction retention.

Cov txheej txheem tsim khoom ntawm siab -kev ntseeg siab alumina metalized ceramics feem ntau suav nrog cov kauj ruam hauv qab no:

1. Raw khoom npaj
Xaiv siab -purity alumina hmoov (Al₂O₃ cov ntsiab lus Ntau dua lossis sib npaug li 95%) thiab tswj cov ntsiab lus tsis huv.
2. Moulding txheej txheem
Qhuav nias los yog daim kab xev casting los xyuas kom meej qhov sib xws thiab ceev.
3. Ua ntej-sintering
Tsawg-kub ua ntej-sintering (kwv yees li 1300 degree) yog ua los txhim kho lub zog ntawm lub cev ntsuab thiab pab txhawb kev ua haujlwm tom ntej.
4. Kev kho deg metallization
Siv molybdenum manganese slurry los luam tawm ntawm cov nplais ceramic, thiab tsim txheej txheej metallization los ntawm siab -kub sintering (kwv yees li 1450℃).
5. Nickel plating kev kho mob
Electroplating npib tsib xee (Ni thickness yog hais txog 3 ~ 5μm) ntawm lub metalized nto los txhim kho cov tom ntej brazing kev ua tau zoo.
6. Kev ntsuas cua nruj
Siv lub helium mass spectrometer leak detector los xyuas kom meej tias huab cua nruj npaum li cas mus txog<1×10⁻⁹Pa·m³/s.
7. Dimension nrhiav thiab tshuaj ntsuam
nruj me ntsis soj ntsuam lub tiaj tus, tuab, thiab qhov chaw qhov raug, thiab qhov ntev kam rau ua feem ntau yog tswj nyob rau hauv ± 0.05mm.

Lub tswv yim: Lub nto roughness ntawm cov ceramic yog tswj hauv qab Ra 0.8μm, uas yuav pab tau rau lub tom ntej brazing zoo.

Nyob rau hauv lub zog tshiab siab -voltage DC contactor, qhov zoo li qub tiv tauj tooj liab txuas nrog cov hlau nplaum ceramic los ntawm lub tshuab nqus tsev. Cov txheej txheem ib txwm tsis muaj raws li hauv qab no:

Tswv yim: Thaum lub sij hawm pretreatment theem, tooj liab seem yuav tsum tau degreased thiab oxide txheej tshem tawm los txhim kho wettability thiab brazing kev ntseeg tau.
 

Kev sib txuas ntawm ntau- hlau qhov chaw hauv lub arc extinguishing chamber feem ntau yog ua los ntawm laser vuam. Cov hauv qab no yog kev siv rau lub qhov rais txheej txheem hauv daim ntawv thov tiag tiag:

Lub tswv yim: Koj tuaj yeem siv lub coaxial kev saib xyuas qhov system los saib xyuas lub pas dej ua ke hauv lub sijhawm tiag tiag txhawm rau txhim kho vuam sib xws thiab tawm los.

Nyob rau hauv lub zog tshiab siab -voltage DC contactors, tus qauv tsim ntawm lub arc extinguishing chamber yog ncaj qha cuam tshuam rau lub extinguishing nyhuv ntawm lub arc thaum disconnected. Lub multi-cov khoom hlau nyob rau hauv lub arc extinguishing chamber feem ntau yog txuas nrog cov txheej txheem laser vuam. Cov ntsiab lus tseem ceeb tshaj plaws suav nrog:

(1). Vuam khoom:Feem ntau stainless hlau los yog hlau alloy, yuav tsum tau zoo laser nqus thiab thermal conductivity.
(2). Laser Parameters:
Laser zog: 300W ~ 1000W (hloov raws li cov khoom thiab thickness)
Spot txoj kab uas hla: 0.2mm ~ 0.6mm
Vuam ceev: 3mm / s ~ 10mm / s
(3). Weld zoo xav tau:
Lub vuam yog nruam thiab sib xws, tsis muaj pores thiab tawg.
Welding depth-to-width ratio>1.5, txaus nkag qhov tob
(4). Vuam txheej txheem kev tiv thaiv:
Siv siab -purity argon tiv thaiv (purity Ntau dua lossis sib npaug li 99.999%) los tiv thaiv vuam oxidation.
(5). Ncej -welding soj ntsuam:
Siv X-ray tsis yog-kev kuaj kev puas tsuaj los xyuas qhov zoo ntawm cov welds sab hauv.
Ua cov tensile thiab shear zog kuaj thaum tsim nyog.

Lub tswv yim: Los ntawm lub siab -precision laser vuam txheej txheem, cov txheej txheem kev ntseeg tau thiab kev pab lub neej ntawm lub arc extinguishing chamber yog guaranteed, uas yog ib tug tseem ceeb guarantee ntawm qhov zoo ntawm lub zog tshiab siab -voltage DC contactors.

Qhov kev ua tau zoo ntawm lub zog tshiab siab -voltage DC contactors nyob ntawm tsis yog nyob ntawm qhov siab -kev tsim khoom zoo ntawm txhua yam khoom, tab sis kuj yog nyob rau hauv kev sib koom ua ke thiab kev sib koom ua ke ntawm txhua txoj kev txuas. Raws li lub sijhawm ntev - tus khub ntawm Xiamen Hongfa Relay Group, peb tsis tsuas yog muab cov khoom tsim nyog tab sis kuj koom nrog cov neeg siv khoom tsim ua ntej, los ntawm kev xaiv cov khoom siv, thiab cov txheej txheem hloov mus rau kev ua pov thawj, muab ntau yam kev daws teeb meem.

Hais txog cov khoom siv sib koom ua ke, peb them nyiaj tshwj xeeb rau cov thermal expansion txuam teeb meem ntawm cov khoom sib txawv. Piv txwv li, lub thermal expansion coefficient ntawm alumina ceramics (7.2 × 10^-6 / degree) yuav tsum tau ua hauj lwm nrog cov metallization txheej (molybdenum-manganese alloy, txog 5.5 × 10^-6 / degree) thiab tooj liab Cheebtsam (17 × 10^-6 / degree). Los ntawm kev kho cov mis metallization (ntxiv silicon oxide los kho qhov nthuav dav coefficient) thiab siv cov qauv hloov pauv hloov pauv hauv cov txheej txheem brazing (xws li wavy tooj liab tso cov yeeb nkab), thermal stress tuaj yeem txo tau zoo, tso cai rau cov khoom tiv thaiv huab cua kub mus txog -40℃~ +150℃.

Hais txog kev sib txuas ntawm cov txheej txheem, peb tau tsim cov txheej txheem kev sib tshuam - nruj heev. Metalized ceramics yuav tsum tau ntxuav plasma (lub zog 300W, lub sijhawm 5min) ua ntej brazing kom tshem tawm cov pa phem ntawm qhov chaw; lub arc extinguishing chamber tom qab laser vuam yuav tsum muaj kev ntxhov siab -relieved annealed ntawm 250℃× 2h ua ntej nws tuaj yeem sib sau nrog lub plhaub loj. Txhua yam khoom muaj cov ntaub ntawv ua tiav cov txheej txheem, suav nrog cov khoom siv, cov txheej txheem tsis ua haujlwm, thiab cov ntaub ntawv xeem, kom ntseeg tau tias txhua yam teeb meem zoo tuaj yeem nyob sai.

Kev txheeb xyuas kev ua tau zoo yog qhov kev sim zaum kawg ntawm kev sib koom ua ke. Peb tau tsim cov txheej txheem kev sim ua tiav rau siab -voltage DC contactor Cheebtsam:

Kev kuaj hluav taws xob:suav nrog kev tiv thaiv kev tiv thaiv (tsawg dua lossis sib npaug ntawm 0.5mΩ), rwb thaiv tsev tsis kam (Ntau dua lossis sib npaug ntawm 1000MΩ) thiab tiv taus qhov ntsuas hluav taws xob (5000V AC / 1min);

Mechanical xeem:kev khiav hauj lwm quab yuam (3-5N), lub neej txhua yam (Ntau dua lossis sib npaug ntawm 100,000 zaug) thiab kev vibration test (20-2000Hz, 3 axes);

Environmental xeem:Lub voj voog kub (-40℃~{1}}℃, 50 zaug), damp cua sov (40℃/ 95%RH, 500h), thiab ntsev tsuag (5% NaCl, 96h).

Los ntawm cov kev tswj hwm nruj nruj, cov khoom tseem ceeb ntawm lub zog tshiab siab -voltage DC contactors peb muab kev pab cov neeg siv khoom cov khoom mus txog kev lag luam- theem ua: tawg peev xwm ntawm 1500VDC / 1000A, hluav taws xob lub neej ntawm ntau tshaj 100,000 zaug, tsis ua hauj lwm tus nqi tsawg dua 0.3‰, tag nrho cov kev xav tau ntawm lub zog hluav taws xob thiab lub zog tshiab - lub zog loj cia systems.

Raws li kev lag luam loj ntawm -voltage DC contactors txuas ntxiv nthuav dav (lub ntiaj teb kev lag luam loj yuav tsum ncav cuag RMB 4.8 billion hauv 2025), peb yuav txuas ntxiv mus rau hauv cov thev naus laus zis xws li alumina metalized ceramics, nqus brazing, thiab laser vuam, thiab muab cov neeg siv khoom zoo dua qub thiab txhim khu kev qha kev sib koom ua ke los ntawm cov txheej txheem kev tsim khoom tshiab thiab txhim khu kev qha ntau dua. hluav taws xob kev lag luam.
