Dab tsi yog lub ntsiab tseem ceeb ntawm bushing nyob rau hauv lub siab voltage khoom?

Nyob rau hauv cov khoom siv siab, bushing yog qhov tseem ceeb txuas sab hauv high voltage neeg xyuas kev coj mus rau Circuit Court. Nws cov haujlwm tseem ceeb tuaj yeem ua tau cov ntsiab lus hauv qab no, sib txuas nrog cov tshwj xeeb siab {{}} pa taws rau hauv cov:
1.Txoj kev rwb thaiv tsev: cais tawm ntawm voltage ntau kom tiv thaiv malfunction.
Cov kev sib tw hauv cov hluav taws xob ntau: Sab hauv cov tshuab hluav taws xob (piv txwv li cov hloov hluav taws xob, GIS) muaj ntau dua lossis sib npaug nrog 110Kv). Yog tias tus thawj coj nkag mus ncaj qha los ntawm lub khauj khaum lossis txuas rau hauv Circuit Sab Nrauv, nws yog qhov yooj yim los ua rau ARC tshem tawm lossis rwb thaiv tsev lossis txawm tawg ntawm lub cuab yeej.
Bushing muaj nuj nqi:
Cov rwb thaiv tsev loj: lub bushing ua kom tiav voltage cov khoom (xws li roj} ep6 roj rwb thaiv tsev, epoxe eptin rwb thaiv tsev, ept.
Fais fab teb tshwj xeeb: lub capacitor bushing tau txais- Qhov hluav taws xob ntawm cov neeg ua haujlwm thiab ua txhaum ntawm cov hluav taws xob hluav taws xob tau zam.
Creep Dive Tswj: Lub bushing thaj tsam li tus qauv kaus lossis txwv tsis pub dhau ntawm cov nplaim dej thiab tiv thaiv los nag, ib puag ncig daus thiab av.
2.Txoj kev txhawb nqa thiab kev kho kom yooj yim: tswj hwm tus neeg saib xyuas kev ruaj khov
Cov yam ntxwv ntawm cov cuab yeej muaj hluav taws xob siab: cov kev sib nqus tam sim no thiab sib nqus ntawm cov kev coj ua sab hauv yuav ua rau kev co lossis kev hloov chaw thaum lub sijhawm ua haujlwm.
Casing Ua Haujlwm:
Cov khoom siv Rigid: Cov khoom siv xyoob ntoo flange kev sib txuas yog nruj, tswj hwm cov hlau los ntawm kev sib cav lossis xoob thiab xoob.
Luv Luv Lej Zog Kuj: Hauv qhov xwm txheej luv luv, cov casing yuav tsum tau tiv thaiv hluav taws xob ntau kom tsis txhob ua tus coj ua lossis lub foob pob hluav taws xob.
3. Ib puag ncig kev deb: Hauv cov khoom tiv thaiv sab hauv
Yuav tsum muaj cov cuab yeej siv hluav taws xob kev kub siab: plua plav, tshuaj ntsuab, thiab lwm yam. Txhawm rau tiv thaiv kev laus lossis xeb ntawm cov hlau seem.
Casing Ua Haujlwm:
Sealing tsim: kev sib txuas ntawm lub vaj tse thiab lub tsev nyob tau ntim lossis vuam txheej txheem los xyuas kom meej qib IP ntawm cov kua lossis tawv txawv teb chaws lub cev.
Huab cua - Rwb cov khoom siv: Silicone roj hmab lossis cov ntaub ntawv rwb thaiv tsev uas siv rau hauv lub plhaub sab nraud los tiv thaiv cov duab UV los ntawm UV Rays, Ozone thiab huab cua sov.
4. Voltage theem kev yoog thiab hloov dua siab tshiab
Kev nyuaj siab ntawm cov hluavtaws siab: Voltage qib yuav sib txawv ntawm cov khoom sib txawv (piv txwv li kev sib txuas ntawm transformer high voltage sab thiab kis kab).
Lub luag haujlwm ntawm bushing:
Voltage txuam: Cov ntsuas hluav taws xob ntawm lub bushing yuav tsum muaj raws li lub kaw lus hluav taws xob kom ntseeg tau lub rwb thaiv tsev kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev nyab xeeb.
Interface Kev Hloov: Lub Bushing muab cov qauv sib txuam (piv txwv li flanges thiab xov los piv cov installation thiab txo cov kev sib chwv tawm thaum lub ntaus ntawv txuas nrog cables thiab tsheb.
V. Thaum tshav kub kub dissipation thiab ntsuas kub nce
Cov teeb meem cua sov hauv cov khoom siv hluav taws xob ntau: Thaum tus neeg xyuas pib dhau los ntawm qhov loj tam sim no, kub yog tsim tawm. Yog tias muaj cua sov dissipation tsis zoo, nws tuaj yeem ua rau rwb thaiv tsev rau hnub nyoog sai dua.
Lub luag haujlwm ntawm bushing:
Kev tsim kev tsav tsheb: qee cov bushings siv cov ntaub ntawv siv zoo thermal, xws li cov hlau flanges, mus pab saib xyuas cua sov dissipation.
Cov khoom siv cua: qee cov roj - Soraed Shafts hloov cua sov los ntawm cov roj ncig lossis kev ntseeg ntuj.
6. Saib xyuas thiab kuaj mob (cov haujlwm) (cov khoom siv ntse)
Txoj kev txhim kho ntawm niaj hnub voltage cov khoom siv: nws yog qhov tsim nyog los soj ntsuam cov mob ntawm cov cuab yeej siv rau kev ntseeg tau.
Bushing muaj nuj nqi:
Ua -} hauv sensors: qee cov khoom siv ntse sib xyaw thiab cov ntaub ntawv xa tawm thiab xa cov ntaub ntawv mus rau kev saib xyuas cov fiber ntau lossis wireless.
Txhaum cov lus ceeb toom: los ntawm kev tsom xam ntawm cov teeb meem sensor, peb tuaj yeem ntes cov teeb meem ntawm rwb thaiv tsev thiab overheating ua ntej, thiab zam kev ua tiav sai sai.
Piv txwv ntawm cov ntawv thov raug cai piv txwv
Transformer High - voltage bushing:
Txuas lub siab voltage winding ntawm lub transformer rau kis tus kab mob thiab tau tiv thaiv qhov siab tshaj plaws ntawm cov kab ke.
Txais yuav cov qauv ntawm cov ntaub ntawv roj roj, nrog rau cov roj av insulitating lossis cov roj hmab silicas los yog silicone roj hmab los.
GIS (roj insulated switchgear) bushing:
Cov neeg ua si hauv SF6 roj, thiab cov bushing ua raws li kev hloov pauv ntawm cov roj thiab huab cua sab nraud.
Nws yog ib qho tsim nyog los ua kom txaus siab rau ob qho kev lag luam hauv roj kev ua tau zoo thiab ua kom sov ua kom sov.
Converter transformer valve sab bushing:
Siv rau HVDC kis, tuaj yeem tiv taus txoj kab sib dhos thiab harmonic superposition.
Cov ntaub ntawv insulating tshwj xeeb siv los tiv thaiv cov kev sib txuam ntawm cov chaw foob hauv qab DC chav hluav taws xob hauv qab.
Kev sib piv nrog tsawg - voltage bushing
Tsis tshua muaj siab qis - voltage bushing cov yam ntxwv
Rwb thaiv tsev yuav tsum muaj ntau voltage thiab uniform fais fab teb los tiv thaiv ib nrab tso tawm. Rwb thaiv tsev tuab yog qhov tseem ceeb thiab lub hom phiaj yog ntawm kev tiv thaiv tougages thiab luv luv voj voog.
Cov Qauv Txheej Txheem (EG capilitor rwb thaiv tsev, sealing rwb thaiv tsev, sealing qauv) yooj yim (ib qho} txheej rwb thaiv tsev, kev sib tw yooj yim)
Cov khoom siv siab them nqi (Ceramics, SF6 roj, Resins Tshwj Xeeb) qis (epoxy cob, nquag silicone roj hmab)
Kev ruaj ntseg kev pheej hmoo tsis ua haujlwm yuav ua rau tawg thiab lub zog loj feem ntau yog txwv rau cov cuab yeej ua kom muaj kev puas tsuaj hauv zos
High - voltage bushing yog ib qho "me me tab sis tseem ceeb tab sis tseem ceeb"}} cov khoom siv siab. Nws tus qauv xav tau coj mus rau hauv tus account hluav taws xob, kho tshuab, cua sov thiab ib puag ncig ua haujlwm kom ntseeg tau ntev} Kev ua haujlwm ntev ntawm cov khoom siv hauv cov xwm txheej huab.
