Ua ntej, nkag siab "applied logic."
Txhawm rau txiav txim siab qhov chaw zoo tshaj plaws ntawm aa 35kV insulated fuse compartment, ob yam khoom tseem ceeb yuav tsum tau ua kom zoo: ua ntej, "tam sim no- txwv kev tiv thaiv" -internal high-voltage txwv tam sim no fuse uas yuam kev cuam tshuam circuits ua ntej luv luv - Circuit Court tam sim no muaj peev xwm ua haujlwm siab; thiab qhov thib ob, "kev rwb thaiv tsev thiab kev sib cais" - lub thawv fuse uas siv cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob sib txuas los kaw thiab cais cov khoom siv hluav taws xob, ua kom muaj kev tiv thaiv siab thiab kev nyab xeeb ntawm kev poob siab.
Qhov no ua rau cov qauv yooj yim rau daim ntawv thov: ib qho 35kV Circuit Court uas yuav tsum muaj kev sib xyaw ua ke ntawm "cov qauv tsim, kev tiv thaiv ceev thiab kev ruaj ntseg siab" yog qhov kev xaiv tsim nyog rau chav tsev insulated fuse. * Cov piv txwv ntawm kev siv tshwj xeeb yog qhia hauv qab no.
II. Tsib yam xwm txheej substation scenarios
1.35kV Chaw Nres Tsheb Kev Pabcuam Transformer Tiv Thaiv
chaw nres tsheb kev pab cuam transformer yog "lub plawv" ntawm lub substation lub hwj chim mov, txawm hais tias nws muaj peev xwm yog feem ntau me me, tab sis yog hais tias nws tawg, nws yuav ua rau tag nrho cov lag luam ntawm lub substation fais fab tuag. Kev siv cov insulated fuse chambers rau kev tiv thaiv tseem ceeb yog tus nqi ntau dua - zoo dua li cov kev daws teeb meem hluav taws xob thaum muaj kev ntseeg siab luv luv ntawm cov transformers sab hauv, ua rau nws tus nqi ntau tshaj - kev xaiv zoo.
2.Shunt Capacitor Bank Tiv Thaiv
Thaum cov tsev txhab nyiaj Capacitor raug kaw thiab cov khoom siv sab hauv tawg, nws yog ib qho yooj yim los tsim cov dej ntws tawm hauv cov dej, ua rau muaj qhov ua tsis tau zoo hauv cov chaw ua haujlwm substations. Lub peev xwm ntim ntawm lub fuse chamber khaws qhov txhaum tam sim no mus rau qhov tsawg kawg nkaus thiab tiv thaiv qhov txhaum ntawm kev sib kis mus rau cov reactors series lossis 35kV busbar, yog li tiv thaiv tag nrho cov busbar seem.
3.Voltage Transformer (PT) Circuit Court
Lub voj voog luv luv hauv PT thib ob winding lossis qhov tsis ua haujlwm sab hauv ntawm PT nws tus kheej tuaj yeem ua rau "sympathetic trip" (sab saum toj Circuit Court breaker dhia), ua rau tag nrho cov hluav taws xob poob thoob plaws hauv lub substation. Chav tsev insulated fuse muab cais, pom qhov thaub qab luv luv - tiv thaiv PT rau kev ua txhaum yooj yim hauv zos thiab cais tawm.
4. Pub thiab ceg Circuit Court
Nyob rau hauv radial 35kV faib tes hauj lwm, lub insulated fuse chamber ua raws li ib tug tiv thaiv tsev nyob rau sab saum toj ntawm cov kab. Nws kuj tseem suav nrog "pom pom tawg" ua haujlwm rau kev txiav cov keyboards, ua kom pom kev pom zoo pom thaum kho thiab ua kom muaj kev nyab xeeb ntau dua rau kev ua haujlwm thiab cov neeg ua haujlwm tu. Ua ntej-fabricated / Box- hom Substations
Cov substations no ntsib qhov chaw loj heev thiab feem ntau nyob hauv thaj chaw sab nraum zoov nkag tau rau cov neeg ua haujlwm. Lub insulating chamber yog compact thiab muaj kev tiv thaiv kev ntsuas ntawm IP54 lossis siab dua, uas txaus siab rau qhov xav tau ntawm thaj chaw me me thiab kev nyab xeeb siab ntawm lub thawv substation.
III. Daim ntawv thov Scenario Raws li Environmental Conditions
Sab nraum zoov thiab ib nrab- cov chaw nres tsheb sab nraum zoov: Nrog rau lub tshuab hluav taws xob insulated thiab UV-cov vaj tsev tiv thaiv, koj tsis tas yuav muaj cov qauv tsim tshwj xeeb.
High Altitude, High Humidity, High Salt Fog thiab Heavy Pollution Areas: Cov khoom siv rwb thaiv tsev muaj kuab paug zoo heev thiab tiv thaiv- cov khoom qub; lawv txo qhov kev pheej hmoo ntawm cov pa phem flashover thiab condensation piv rau qhib layouts.
Kev kho kom haum thiab muaj peev xwm nthuav dav ntawm cov chaw nres tsheb uas twb muaj lawm: Lub siab hloov pauv ntawm lub rwb thaiv tsev chamber tso cai rau nws txuas nrog cov switchgear uas twb muaj lawm nrog me me los yog tsis muaj zog cuam tshuam, yog li txo lub qhov rais retrofit.
IV. INTRODUCTION Cov ntsiab lus tseem ceeb rau Scenario-Txoj Kev Xaiv
Cov xwm txheej sib txawv yuav tsum muaj qhov tseem ceeb sib txawv: rau qhov chaw nres tsheb kev pabcuam transformers thiab lub tsev txhab nyiaj capacitor, qhov tseem ceeb yog muab tso rau ntawm qhov muaj peev xwm tawg tau (feem ntau ntau dua lossis sib npaug rau 31.5 kA) thiab sib piv cov yam ntxwv nkhaus nkhaus; rau sab nraum lub thawv substations, qhov tseem ceeb yog muab tso rau ntawm qhov ntsuas IP thiab kub nce; thiab rau thaj chaw siab siab, cov rwb thaiv tsev sab nraud yuav tsum tau kho qhov siab. Nws raug nquahu kom xam qhov siab tshaj plaws luv luv - tam sim no thiab txiav txim siab qhov ntsuas tam sim no ntawm lub fuse thiab qhov ntsuas tam sim no ntawm lub combustion chamber.
Cov lus nug nquag
Q1: Puas tuaj yeem siv cov kab hluav taws xob insulated hauv 10 kV?
Cov khoom tsim los nrog cov chav kawm tshwj xeeb ntawm 40.5 kV rau 35 kV insulated fuse cell thiab tsis tuaj yeem "downgraded" rau siv hauv 10 kV systems. Lub fuse chamber nrog cov ntsuas hluav taws xob sib txuas yuav tsum raug xaiv rau daim ntawv thov ntawm 10 kV.
Nqe Lus Nug 2: Puas yog cov chaw ua haujlwm sab hauv tsev puas xav tau lub "insulated" chamber?
Ib tug qauv compartment yog txaus yog hais tias tus switchgear nws tus kheej muab kev tiv thaiv txaus thiab txij nkawm kom ua tau raws li cov qauv; Txawm li cas los xij, kev ruaj ntseg rov ua dua los ntawm kev rwb thaiv tsev tseem muaj txiaj ntsig nyob rau hauv cov cheeb tsam uas muaj qhov txwv tsis pub siv, cov chaw siv tau los yog cov phiaj xwm retrofit.
Q3: Dab tsi yuav tsum xav txog thaum xaiv lub fuse chamber rau lub tsev txhab nyiaj capacitor?
Qhov tseem ceeb yog los xyuas qhov tsis yog - melting tam sim no thiab melting yam ntxwv ntawm lub fuse kom ntseeg tau tias nws muaj peev xwm tiv taus kaw inrush tam sim no thaum tiv thaiv cascading explosions nyob rau hauv cov kev tshwm sim ntawm ib tug sab hauv capacitor txhaum. Q4: Yuav ua li cas kho qhov ntsuas ntawm qhov siab?
Rau txhua 1,000 meters ntawm qhov siab, theem ntawm cov rwb thaiv tsev sab nraud yuav tsum nce li ntawm 8% -10%; yog tias tsim nyog, xaiv cov khoom uas txhim khu kev rwb thaiv tsev los yog ua kom huab cua tshem tawm qhov deb.
Q5: Nws yuav siv sijhawm ntev npaum li cas txhawm rau txhim kho lub substation uas twb muaj lawm?
Insulated fuse compartments feem ntau yog tsim los nrog modular plug-ins uas siv sijhawm li ob peb teev los hloov kho; qhov cuam tshuam tuaj yeem txo qis los ntawm kev thauj khoom thauj khoom thauj.
Q6: Lub peev xwm saib xyuas kev txawj ntse tuaj yeem ua ke?
Yog lawm. ' Wireless ntsuas kub ntsuas thiab ib feem tso tawm sensors tuaj yeem ntsia tau rau hauv lub rwb thaiv tsev chamber kom xa cov ntaub ntawv mus rau lub chaw nres tsheb qhov xwm txheej-raws li kev saib xyuas qhov kev saib xyuas.
