Ob Chav Hla Yoke Phaj feem ntau yog siv hauv high-voltage thiab ultra-high-voltage fais fab kab. Tag nrho cov txheej txheem tsim khoom, los ntawm cov khoom siv raw mus rau cov khoom tiav, suav nrog ntau cov kauj ruam, txhua qhov ncaj qha txiav txim siab lub zog, lifespan, thiab kev nyab xeeb.
Ob Chav Hla Yoke Phaj feem ntau yog siv hauv high-voltage thiab ultra-high-voltage fais fab kab. Tag nrho cov txheej txheem tsim khoom, los ntawm cov khoom siv raw mus rau cov khoom tiav, suav nrog ntau cov kauj ruam, txhua qhov ncaj qha txiav txim siab lub zog, lifespan, thiab kev nyab xeeb.
Raw Material Inspection: Cov khoom zoo yog qhov tseem ceeb rau lub zog. Peb feem ntau xaiv qis- alloy siab- lub zog steel daim hlau xws li Q355B thiab Q355D, thiab ua cov tshuaj lom neeg muaj pes tsawg leeg, kuaj cov cuab yeej siv tshuab, thiab kuaj xyuas cov phaj thickness, flatness, thiab tsos (tsis muaj kab nrib pleb, tsis muaj delamination). Tsuas yog cov hlau phaj uas dhau qhov kev tshuaj ntsuam no mus rau txheej txheem blanking.
Kho thiab Shaping: xyuas kom meej qhov flatness yuam kev ntawm lub phaj nto yog tsawg dua los yog sib npaug rau 1mm / m. Kev tuav los yog kev sib tsoo tshuab yog ua los tshem tawm cov ntse burrs ntawm lub phaj npoo thiab lub qhov qhib. Chamfering yog siv rau qhov tseem ceeb ntawm kev ntxhov siab los tiv thaiv khawb rau cov neeg tsim khoom thiab txhim kho zinc txheej adhesion.
Kub-dip galvanizing: Qhov no yog txheej txheem tseem ceeb rau kev tiv thaiv xeb ntawm Ob Chav Hla Yoke Phaj. Nws ua kom lub cev tsis sib xws, du, thiab tsis muaj teeb meem zinc txheej nrog lub thickness Ntau dua lossis sib npaug li 85μm. Tom qab galvanizing, zinc nodules thiab burrs raug tshem tawm, thiab cov haujlwm ntawm lub qhov raug tshuaj xyuas qhov kev hloov pauv vim thermal expansion thiab contraction. Dimensions yog xyuas kom haum rau cov drawings, thiab installation yog du thiab unobstructed.
Kev tshuaj xyuas cov khoom tiav: Kev tshuaj xyuas tag nrho yog ua tiav, suav nrog cov tsos, qhov ntev, qhov sib luag, qhov tawv, cov khoom siv, kev puas tsuaj tensile kuaj, thiab kuaj load. Tsuas yog cov khoom tsim nyog raug xa mus rau tus neeg siv.
Ob Chav Hla Yoke Phaj feem ntau yog siv rau kev ncua ob txoj hlua insulator. Cov kev qhia tshwj xeeb sib txawv sib txawv ntawm qhov sib txawv voltage, tus neeg xyuas pib hla- ntu, ntauwd kev nyuaj siab, thiab ib puag ncig. Common specifications yog raws li nram no:
120-Grade Ob Chav Hla Yoke Phaj: Ib qho qauv zoo heev, ntsuas qhov tawg load 120kN, phaj thickness 14mm lossis 16mm, sab qhov Φ20/Φ22, qhov ntev 300–400mm × 100–120mm × 14/16mm. Feem ntau siv nyob rau hauv 110kV kis tau tus mob kab, 220kV lub teeb-load kab, thiab cov pa kab uas tsis muaj cua, tsis muaj icing, thiab tsis loj spans.
160-Qib Ob Chav Hla Yoke Phaj: Feem ntau siv rau hauv siab- cov kab hluav taws xob, muab cov nqi siab-effectiveness, rated breaking load 160kN, phaj thickness 16mm lossis 18mm, sab qhov Φ–22/Φ24, qhov ntev 50104 × 140mm 16/18 mm. Siv nyob rau hauv 220kV kab. Mainstream kis tau tus mob thiab substation kab nkag thiab tawm yog ob-txoj hlua ncua;
200-qib Ob Chav Hla Yoke Phaj: Feem ntau siv hauv cov kab hnyav-, nrog rau qhov ntsuas tawg ntawm 200kN. Phaj tuab yog 18mm lossis 20mm, nrog sab qhov ntawm Φ26 / Φ28. Qhov loj me yog 420-520mm × 140-160mm × 18/20mm. Feem ntau yog siv hauv 220kV hnyav- cov kab thauj khoom thiab 500kV lub teeb- mus rau- cov kab nruab nrab, xws li hauv thaj chaw uas muaj dej khov hnyav, cua daj cua dub, thiab qhov siab siab.
Ob Chav Hla Yoke Phaj muaj cov qauv yooj yim heev, lub zog siab, thiab kub -dip galvanized rau kev tiv thaiv corrosion. Nws lub neej ua haujlwm ib txwm tuaj yeem ncav cuag 20-30 xyoo. Yog tias siv nyob rau hauv ib puag ncig hnyav, kev tu thiab tu kom zoo yog qhov tsim nyog kom tsis txhob muaj kev phom sij rau kev nyab xeeb hauv Circuit Court.
Kev soj ntsuam niaj hnub
Cov kab tsis tu ncua yuav tsum tau tshuaj xyuas txhua 1-2 xyoos; nyob rau hauv hnyav icing thiab high-cua qhov chaw, txhua txhua 6-12 lub hlis. Tshawb xyuas tag nrho deformation, khoov, tawg, puas los yog xeb zinc txheej, xoob bolts thiab ceev, thiab khib nyiab thaum tuav.
Kev tiv thaiv corrosion
Txawm hais tias cov hlau txuas yog kub-dip galvanized rau kev tiv thaiv corrosion, kev siv ntev yuav ua rau muaj pob, khawb, thiab xeb. Me me corrosion tuaj yeem kov nrog xim; nruab nrab xeb yuav tsum tau tshem tawm xeb; thiab xeb hnyav yuav tsum tau hloov cov ntawv sib txuas kom tiv thaiv kev tawg.
Kev tu thiab tu
So ntawm qhov chaw nrog dej huv los yog cov tshuaj ntxuav tes kom huv si kom lub phaj huv si thiab ua kom qeeb corrosion. Tshem tawm cov khib nyiab los ntawm qhov kom tsis txhob muaj av thiab plua plav los ntawm kev nkag mus, uas tuaj yeem ua rau cov bolts xoob thiab tsis sib xws. Kev tu tsis tu ncua ua kom muaj kev sib txuas nruj.
