Lub yoke phaj yog ib qho tseem ceeb ntawm kev sib txuas ntawm cov khoom siv hluav taws xob thiab cov khoom xa tawm hauv cov kab sib txuas, cov chaw sib txuas, thiab cov tshuab fais fab. Nws feem ntau yog cov phaj hlau tiaj tus nrog ntau lub qhov. Nws lub luag haujlwm tseem ceeb yog txhawm rau txuas cov insulators, U-zoo li lub nplhaib, bolts, nro clamps, thiab lwm yam khoom siv hauv cov khoom siv los yog sib npaug, sib npaug faib cov neeg xyuas pib nro, cua load, thiab icing load, ua kom lub zog ruaj khov ntawm lub zog hluav taws xob hauv kev ua haujlwm nyuaj. Cias muab, nws zoo li "universal adapter" nyob rau hauv lub hwj chim fittings -txuas crossarm ntawm ib sab thiab ib tug insulator hlua ntawm lwm yam, faib conductor load nyob rau hauv nruab nrab, ua rau nws ib tug indispensable "kev nyuaj siab- bearing hub" rau siab -voltage/ultra-volt{7.
Tsawg- carbon steel
Tsawg- carbon steel hais txog cov pa roj carbon zoo tib yam uas muaj cov ntsiab lus carbon tsawg dua lossis sib npaug li 0.25%. Hauv tsev, Q235 (yield zog 235MPa) feem ntau yog siv, thaum thoob ntiaj teb nws sib raug rau SS400 thiab A36. Nws yog cov khoom siv hlau yooj yim tshaj plaws hauv kev lag luam. Nrog lub zog tensile ntawm 370-500MPa, nws tuaj yeem tiv taus cov kab sib xyaw ua ke, tsis yooj yim nkig, thiab tsis tawg thaum khoov thiab stamping. Nws yog qhov tsim nyog rau txoj haujlwm txoj haujlwm ntawm lub qhov thiab tsis sib xws. Txiav, drilling, xuas nrig ntaus, thiab kub dabtsi yog khoov yog ib qho yooj yim, ua rau muaj kev ua tau zoo ntau lawm, tus nqi qis, thiab tus nqi - ua tau zoo me me - batch customization. Cov xwm txheej tseem ceeb ntawm daim ntawv thov suav nrog 10kV, 35kV, thiab 110kV cov kab sib txuas ua ke, thaj chaw hauv nroog zoo tib yam, cov pa hluav taws xob sib txuas sib txuas, busbar mounting daim hlau, kho vajtse hauv cov cheeb tsam uas tsis yog{18}}corrosive, tsis yog{19}} thaj chaw ntug hiav txwv, tsis yog - thaj chaw tshuaj lom neeg. Nws yog ib txoj haujlwm tseem ceeb rau tej yaam num ua qhov tseem ceeb ntawm cov nqi-zoo.
Kub-dip galvanized siab- lub zog carbon steel
Nws yog qhov nyiam qhov hnyav -lub luag haujlwm Yoke Plate, nrog cov ntsiab lus carbon ntawm 0.18%-0.22%. Qhov sib ntxiv ntawm cov me me ntawm Mn thiab Si txhim kho nws lub zog, ua rau nws tsis tshua muaj zog dua li siab - carbon steel. Nws tsis tshua muaj deformation thiab breakage nyob rau hauv hnyav loads, pom zoo qaug zog tsis kam, thiab nws tsis tshua muaj kev tawg nyob rau hauv ntev - vibration. Nws kuj yog kub-dip galvanized, muab kev tiv thaiv corrosion lub neej ntawm 20{19}}25 xyoo. Nws yog qhov ruaj khov dua li cov hlau tsis tshua muaj carbon tsawg, tab sis nws tus nqi yog 20% -40% siab dua Q235. Nws kuj muaj zog dua, yuav tsum tau tshwj xeeb pwm rau drilling thiab xuas nrig ntaus, ua rau me ntsis ua zog siv zog. Cov ntawv thov suav nrog 220kV, 400kV, thiab 500kV cov kab sib txuas tseem ceeb, qhov ntev ntev, cov cheeb tsam uas muaj qhov hnyav hnyav, thiab cua daj cua dub, siab tam sim no busbar mounting daim hlau nyob rau hauv substations, converter chaw nres tsheb kev twb kev txuas hardware, thiab cua fais fab kis kab.
(3) Alloy steel qauv
Alloy structural steel Yoke Plate yog siv rau ultra-high voltage/extra-high voltage thiab hnyav hnyav- load applications. Alloy structural steel yog tsim los ntawm kev ntxiv cov ntsiab lus alloying xws li Cr, Mo, Ni, thiab V rau carbon steel, thiab tom qab ntawd forging thiab cua sov- kho nws kom ua tiav ultra- siab zog thiab toughness. Cov qhab-nees sawv cev suav nrog 40Cr thiab 35CrMo, suav nrog siab -kawg load-cov kabmob steel. Lub zog tensile ntawm alloy structural steel yog 900-1200MPa, 2-3 npaug ntawm qis- carbon steel, thiab nws tuaj yeem tiv taus qhov kawg loads tshaj 100kN, ua rau nws yog "sab saum toj- ntawm -the{{21}{21}} cov khoom siv hluav taws xob ultra. Nws tsis yooj yim rau tawg nyob rau hauv ntev -lub sij hawm cua vibration thiab kub sib txawv (-40℃~ +60 degree), muaj kev cuam tshuam zoo toughness, thiab tsis yooj yim tawg thaum dej khov detaches los yog conductors gallop. Kub-dip galvanizing thiab passivation kev kho mob, los yog Dacromet txheej, muab kev tiv thaiv corrosion lub neej ntawm 25-30 xyoo, ua rau nws haum rau ib puag ncig hnyav heev. Alloy structural steel Yoke Phaj yog siv nyob rau hauv ± 800kV UHVDC thiab 1000kV UHVAC kab, nrog rau peb-los yog plaub-txoj hlua insulator txuas daim hlau thiab loj-tonnage nro daim hlau.
(4) aluminium alloy
Aluminium alloys yog ua los ntawm txhuas, nrog cov ntsiab lus ntxiv xws li Mg, Si, thiab Cu. Cov qib siv feem ntau suav nrog 6061 (T6 kev kho cua sov) thiab 6063. Lawv qhov ceev tsuas yog ib qho - peb ntawm cov hlau, ua rau lawv cov khoom siv hlau hnyav. Nrog rau qhov ceev ntawm 2.7 g / cm³ (steel 7.85 g / cm³), lawv txo qhov hnyav los ntawm 60% rau tib qhov ntev. Siab- qhov siab qhov siab (ntauwd ua haujlwm) yuav tsum tsis muaj cov cuab yeej loj thiab tuaj yeem ua tiav manually, txo qhov kev pheej hmoo ntawm kev ntog. A dense alumina film forms on the aluminum surface, isolating air and moisture, eliminating the need for hot-dip galvanizing. Lawv muaj kev ua neej nyob ntawm 20-25 xyoo nyob rau hauv ntug dej hiav txwv, thaj chaw muaj tshuaj lom neeg, thiab qhov chaw siab -cov av noo, tsis muaj kev txhawj xeeb txog xeb. Lub Yoke Phaj no yog siv nyob rau hauv 10kV thiab 35kV qis-voltage fais fab faib kab, haum rau luv luv, tsis-icing ib puag ncig, thiab ib puag ncig hauv nroog.
(5) Stainless hlau
Stainless hlau muaj ntau dua los yog sib npaug rau 10.5% chromium. 304 (18-8 stainless hlau, 18% chromium, 8% npib tsib xee) yog ib qho dav - hom phiaj qib, thaum 316 (nrog 2% -}3% molybdenum) muaj kev tiv thaiv zoo tshaj rau cov kua qaub, a, al, al, al, al, anti-corrosion hlau. 304 yog resistant rau corrosion zoo tib yam, thaum 316 yog resistant rau ntsev tsuag, acids, alkalis, thiab seawater. Nws muaj kev pab cuam lub neej tshaj 30 xyoo nyob rau hauv ntug hiav txwv dej, tshuaj nroj tsuag, thiab offshore platforms, thiab yuav tsis xeb. Nws lub zog tensile yog 510-620MPa, ze rau Q235, muab kev cuam tshuam thiab qaug zog tiv thaiv, ua rau nws haum rau nruab nrab loads thiab vibration ib puag ncig. Nws muaj qhov ntev - ua kom zoo nkauj zoo nkauj, yuav tsum tsis muaj txheej txheej, thiab yooj yim los ntxuav cov roj thiab hmoov av, ua rau nws tsim nyog rau thaj chaw huv si thiab sab nraum zoov kab. Nws muaj feem xyuam rau cov ntug dej hiav txwv offshore cua ua liaj ua teb, hla hiav txwv kis kab, tshuaj lom neeg chaw ua si substations, seawater desalination cog fais fab tshuab, offshore platforms, thiab chaw nres nkoj davhlau ya nyob twg fais fab mov kab. Rau lub sij hawm ntev raug rau dej hiav txwv thiab ntsev tsuag, stainless hlau yog tib lub sij hawm ntev.
Yoke Plate tej zaum yuav zoo li yooj yim, tab sis qhov tseeb, "cov ntaub ntawv txiav txim siab txog lub neej, thiab kev siv tes ua haujlwm txiav txim siab txog kev nyab xeeb." Xaiv cov khoom tsim nyog tuaj yeem ua rau cov khoom siv hluav taws xob tu- pub dawb rau 20-30 xyoo, tsis txhob muaj hluav taws xob; xaiv cov khoom tsis raug yuav ua rau xeb thiab hloov txhua 1-2 xyoos, lossis txawm tias tawg ua rau muaj kev nyab xeeb loj.
