Koj tuaj yeem paub txhua yam khoom tshiab yuav raug luam tawm ntawm no, thiab ua tim khawv rau peb txoj kev loj hlob thiab kev tsim kho tshiab.
Hnub Tim: 07-29-2025
Nrog peb txoj kev hloov pauv mus rau cov tshuab hluav taws xob hauv av tas li, qhov xav tau kev faib hluav taws xob txhim khu kev qha, muaj kev nyab xeeb thiab yoog tau nce ntxiv txhua hnub. Qhov no xav tau kev teeb tsa cov khoom siv sib txuas ntawm lub luj tshib kom txuas thiab txiav cov hluav taws xob uas muaj zog kom muaj kev nyab xeeb.
Cov connectors no txuas cov cables hauv av rau cov bushings tuag pem hauv ntej ntawm padmount transformers, kom ntseeg tau tias muaj kev sib txuas zoo thiab txhim khu kev qha ntawm cov cables hluav taws xob thiab cov transformers.
Yog li ntawd, qhov tseeb yog dab tsiLoabreak lub luj tshib txuasNws ua haujlwm li cas?
Cia peb teb cov lus nug no, ntawm ntau lwm tus, hauv tsab xov xwm no.
Lub luj tshib nres thauj khoom yog ib qho txuas sib cais, rwb thaiv tsev, siv rau hauv feem ntau cov kab ke hluav taws xob qis-rau-nruab nrab rau kev hloov pauv thauj khoom muaj zog. Cov txuas luj tshib nres thauj khoom yog siv los txuas cov xov hlau hauv av, cov xov hlau nruab nrab-voltage rau cov transformers, switchgear thiab lwm yam khoom siv.
Cov connectors no muab kev sib txuas hluav taws xob thiab hluav taws xob uas muaj kev tiv thaiv tag nrho thiab nkag mus rau hauv dej, thiab tau tsim los ua lossis rhuav tshem kev sib txuas hauv qab kev thauj khoom. Lawv feem ntau raug ntsuas rau 15 kV, 25 kV thiab 35 kV systems.
Txhawm rau kom ntseeg tau tias muaj kev sib pauv tau thiab kev ua haujlwm zoo nyob rau hauv qhov hnyav thiab hla ntau yam hluav taws xob, feem ntau cov luj tshib tawg ua tau raws li cov qauv kev lag luam zoo liIEEE 386.
Cov lauj kaub tais diav uas siv cov cuab yeej kub kub los thauj cov mov ci ua rau muaj kev sib txuas thiab rov txuas dua. Nov yog qee yam ntawm nws cov yam ntxwv tseem ceeb:
Qhov no yog lawv lub luag haujlwm tseem ceeb, vim lawv tuaj yeem cuam tshuam thiab txuas qhov kev sib txuas ntawm txog li 200 A, thaum txiav lossis cais cov khoom siv sib txawv thiab yam tsis muaj kev tshem tawm tag nrho lub kaw lus.
Lub taub hau ceramic electrode txuas ntxiv mus dhau lub cev ntawm lub luj tshib thiab pab tua lub arc uas tsim thaum cais qhov kev sib txuas hauv qab kev thauj khoom.
Cov neeg ua haujlwm siv tau cov cuab yeej siv hluav taws xob uas muaj cov khoom siv rwb thaiv tsev (cov pas nrig kub) los rub tawm thiab ntxig lub luj tshib. Ntawm no, lub tshuab caij nplooj ntoos hlav siv los txo qhov kev ntxhov siab ntawm hluav taws xob thiab kev hnav, thaum tswj kev pib arc.
Cov ntsiab lus kuaj capacitive tau muab tso ua ke rau hauv cov luj tshib ntawm qhov chaw tawg kom paub tseeb tias qhov kev sib txuas puas ua haujlwm ua ntej thiab tom qab kev txiav tawm. Cov ntsiab lus capacitive no tsis txuas nrog tus neeg hlau tseem ceeb.
Tag nrho cov khoom no ua haujlwm sib haum xeeb kom tso cai rau cov khoom siv txuas hluav taws xob txuas thiab txiav cov kev sib txuas thaum tswj kev nyab xeeb ntawm tus neeg teb xov tooj thiab lub kaw lus.
Cov khoom sib txuas ntawm cov khoom siv thauj khoom muaj ntau hom raws li qib voltage, qhov chaw siv thiab kev teeb tsa. Cia peb tham txog qee hom uas siv ntau tshaj plaws:
Cov luj tshib tawg thauj khoom tuaj yeem ua ntau yam voltage, qee qhov ntawm lawv yog:
15kV:Lawv tau tsim los rau cov voj voog txog li 15 kV, nrog rau qhov tam sim no tas mus li ntawm 200 Amperes. Cov khoom sib txuas 15 kV no tau tiv thaiv tag nrho, muab tso rau hauv dej thiab qee zaum muaj cov khoom sib cuag bimetal.
25kV:Cov no 25 kv load break elbowsraug ntsuas rau cov kab ke txog li 24 kV, feem ntau ntawm 250 A txuas ntxiv tam sim no nrog 300 A lub peev xwm overload rau 8 teev. Txhawb nqa XLPE lossis EPR insulated cables nrog conductor cross-sections los ntawm ~ 25–120 mm². Lawv feem ntau siv rau hauv cov kab ke hluav taws xob niaj hnub thiab muab txoj hauv kev nyab xeeb thiab ruaj ntseg los txuas / disconnect ntau lub voj voog.
35kV:Txawm hais tias 25Kv lub luj tshib tawgFeem ntau siv, 35 kV kuj siv rau qee qhov kev siv tshwj xeeb. Lawv tuaj yeem tiv taus qhov tam sim no tas mus li txog li 200 Amperes thiab qhov ntsuas voltage lossis txog li 35 kV. Txhawm rau tswj qhov voltage loj no, lawv muaj cov khoom siv peroxide-cured EPDM rwb thaiv tsev thiab semiconducting shield, lub connector coppertop compression, tin-plated copper probe nrog arc-follower tip, thiab cov ntsiab lus kuaj capacitive xaiv tau.
Cov khoom siv txuas hluav taws xob tuaj yeem ua ntau yam kev teeb tsa kom haum rau ntau daim ntawv thov
Tus qauv loadbreak luj tshib:Cov no yog siv los txuas ib txoj hlua rau ib daim khoom siv (piv txwv li transformer, switchgear). Lawv siv cov lus qhia ceramic probe los txhawb kev ua haujlwm muaj zog.
Lub luj tshib hom sib tshuam:Lawv kuj hu ua ntau txoj kev lossis tee configuration elbows. Lawv tso cai rau kev sib txuas ntawm ntau lub xov hlau ua ke hauv ib lub tsev insulated. Cov kev teeb tsa feem ntau suav nrog 2-point, 3-point, thiab 4-point junction elbows siv rau hauv cov qauv faib khoom nyuaj.
Nrog qhov chaw sim capacitive:Cov luj tshib no muaj xws li lub sensor capacitive uas ua los ntawm cov pwm los qhia txog qhov hluav taws xob ntawm lub voj voog (feem ntau yog li ntawm 10–12% ntawm qhov hluav taws xob mus rau hauv av). Qhov no ua rau muaj kev txheeb xyuas qhov hluav taws xob kom muaj kev nyab xeeb yam tsis tas yuav muab lub zog rau lub connector ncaj qha.
Tsis muaj qhov chaw sim:Cov no yog tsim rau kev teeb tsa qhov twg kev kuaj hluav taws xob tau ua nyob rau lwm qhov, cov luj tshib no tsis tuaj yeem muab cov lus teb tam sim ntawd rau theem-rau-av.
Txawm hais tias feem ntau cov luj tshib tawg los nrog tus qauv tsim uas nkag tau hauv dej, qee qhov kuj tuaj nrog cov qauv tsim uas tiv taus xeb.
Cov Qauv Tsim Dej
Cov qauv tsim uas siv tau rau hauv dej no tuaj yeem ua haujlwm tau zoo hauv qab dej lossis hauv av uas ntub dej thaum sib txuas nrog cov bushings lossis plugs sib xws. Piv txwv li, Anhuang's25 kV load break elbowsmuab kev sib txuas tag nrho, sib cais tau.
Cov Qauv Uas Tiv Thaiv Kev Kub Ntxhov
Qee lub luj tshib thauj khoom siv rau hauv qhov chaw muaj xeb, xws li thaj chaw ntug dej hiav txwv lossis cov chaw tsim tshuaj lom neeg. Lawv muab cov kev sib txuas uas tau tshuaj xyuas tag nrho thiab sib cais tau nrog cov khoom siv hlau tsis xeb thiab cov khoom siv roj hmab EPDM uas tsim los tiv thaiv kev puas tsuaj ib puag ncig hauv cov xwm txheej hnyav.
Nov yog qee qhov kev siv tiag tiag ntawm cov luj tshib tawg:
Kev faib hluav taws xob hauv av
Cov luj tshib tawg thauj khoom siv dav dav los txuas cov xov hlau hauv av nruab nrab rau cov transformers, switchgear, thiab lwm yam khoom siv yam tsis cuam tshuam kev pabcuam.
Cov transformers thiab switchgear uas tau teeb tsa rau ntawm pad
Lawv ua kom muaj kev nyab xeeb, ua haujlwm kub thaum txuas lossis txiav cov khoom siv ntawm cov kab ke nyob xws li cov transformers thiab switchgear uas tau teeb tsa rau ntawm pad.
Kev teeb tsa rau kev lag luam, kev siv hluav taws xob thiab kev lag luam
Cov luj tshib tawg thauj khoom siv thoob plaws cov chaw hloov pauv hluav taws xob, cov tshuab hluav taws xob hauv kev lag luam, thiab cov tsev lag luam uas xav tau kev faib seem thiab kev hloov pauv thauj khoom.
Cov liaj teb siv hluav taws xob los ntawm cua, hnub ci thiab cov chaw ua liaj ua teb uas siv hluav taws xob rov ua dua tshiab
Cov no zoo tagnrho rau kev teeb tsa hluav taws xob rov ua dua tshiab (xws li cua thiab hnub ci ua liaj ua teb) qhov twg kev ua haujlwm yooj ywm, muaj zog pab txo lub sijhawm tsis ua haujlwm thaum lub sijhawm kho.
Kev Tshawb Fawb thiab Kev Tsheb Ciav Hlau
Siv rau hauv cov chaw ib puag ncig hnyav xws li kev ua haujlwm hauv kev khawb av thiab kev tsheb ciav hlau lossis metro hluav taws xob kom tswj tau lub zog tas mus li thaum cais cov ntu rau kev pabcuam.
Cov khoom siv sib txuas ntawm lub luj tshib yog qhov yuav tsum muaj thaum koj xav cais qee qhov ntawm lub zog hluav taws xob nruab nrab, hauv av. Lawv muab txoj hauv kev txhim khu kev qha thiab ruaj ntseg los kho qee qhov ntawm cov voj voog yam tsis cuam tshuam rau tag nrho cov khoom siv hluav taws xob.
Yog koj tab tom nrhiav kev yuav khoom25 kV loadbreak lub luj tshib connectorsrau koj daim ntawv thov, koj yuav tsum mus saib Anhuang cov khoom ntau yamlub luj tshib tawg thauj khoom.
