Peb Qhov Kev Ua Phem Txhaum Loj Loj ntawm Condensation thiab Moisture hauv Switchgear
Cov tee dej uas tsim los ntawm condensation ua raws li qhov chaw ntawm cov khoom siv hlau thiab cov ntaub ntawv insulating, ua rau muaj cov tshuaj tiv thaiv kab mob uas nws muaj kev phom sij tshaj qhov kev cia siab:
Kev poob qis hauv kev ua haujlwm rwb thaiv tsev: High-cov av noo ib puag ncig txo lub zog ntawm huab cua rwb thaiv tsev, thiab cov yeeb yaj kiab dej ua rau ntawm cov khoom siv insulating, yooj yim ua rau kev taug qab, flashover, lossis txawm tias rwb thaiv tsev tawg thiab luv luv Circuit Court. Qhov kev pheej hmoo no tshwj xeeb yog qhov tseem ceeb rau cov khoom siv precision zoo ligis roj insulated switchgear (GIS), raws li noo noo nkag tuaj yeem cuam tshuam qhov chaw ntim roj thiab ua rau muaj kev puas tsuaj irreversible. Tawm - ntawm - cov khoom siv pabcuam - suav nroggas insulated substation gisunits- ntsib txoj kev pheej hmoo siab ntawm condensation vim qhov kub thiab txias sab hauv, ua rau muaj xwm txheej tshwm sim thaum lub zog rov qab los;
Corrosion thiab tsis ua haujlwm ntawm cov khoom siv hlau: Condensation ua rau corrosion ntawm conductive hlau qhov chaw xws li terminal blocks thiab busbars, uas yuav ua rau AC los yog DC luv circuits thiab av faults. Rau cov khoom tseem ceeb xws ligis circuit breaker, xeb ntawm kev khiav hauj lwm mechanisms tuaj yeem ua rau jamming, ua rau tsis tiav qhib lossis kaw ntawm cov keyboards thiab ua rau muaj kev sib tsoo loj; Txawm tias tus qauv switchgear raug kev txom nyem los ntawm cov txheej txheem xeb, uas cuam tshuam kev ua haujlwm ib txwm muaj;
Qhov tseem ceeb shortened khoom lifespan: Ib qho chaw ntub dej ua rau cov ntaub ntawv rwb thaiv tsev laus thiab kev puas tsuaj rau cov khoom siv hluav taws xob. Cov ntaub ntawv txheeb cais qhia tau hais tias lub tshuab hloov pauv tau raug rau cov dej noo ntev ntev - suav nroggis roj insulated switchgear-muaj lub neej luv luv los ntawm 3-5 xyoo, nrog rau kev ua haujlwm thiab kev saib xyuas tus nqi nce ntau dua 40%.
Nyob ntawm daim ntawv thov scenario, pob nyiaj siv, thiab cov kev xav tau (seb rau tus qauv hloov pauv lossisgas insulated substation gis), cov kev daws teeb meem suav nrog "Kev Teb Thaum Muaj Xwm Ceev - Kev daws teeb meem hauv paus - Kev Ua Haujlwm Txawj Ntse thiab Kev Txhim Kho" tuaj yeem txais yuav, ntsuas qis- nqi, tau txais txiaj ntsig sai nrog lub sijhawm ntev - ruaj khov thiab kev ntseeg tau.
(1) Tsawg-Cov Nqi Them Thaum Muaj Xwm Ceev: Kev tswj cov av noo nrawm yam tsis muaj hluav taws xob cuam tshuam (tsim rau cov txee qub, cov xwm txheej uas muaj peev nyiaj tsawg, thiab tseem muaj kev tiv thaiv raugis circuit breakerenclosures)
High -kev ua tau zoo desiccant hnab txoj kev(tus nqi ≈ 20 RMB / txee / xyoo)
Nws yog qhov zoo tshaj plaws los siv 500-1,000g desiccant hnab uas muaj calcium chloride (CaCl₂), nyiam dua cov qauv nruab nrog lub tais tais;
Kev teeb tsa qhov chaw: dai rau hauv qab kaum ntawm lub txee (s deb ntawm cov khoom siv hluav taws xob nyob), tso 1-2 hnab rau ib lub txee (los yog 1 lub hnab nyob ze ntawm qhov chaw pabcuam ntawmgis roj insulated switchgear);
Kev tu ntau zaus: Tshawb xyuas txhua hli; hloov tam sim ntawd thaum lub tais ntim puv los yog lub hnab desiccant ua nyuaj thiab clumped.
Pom qhov kub thiab av noo saib xyuas(Tus nqi ≈15 yuan / unit, kev pab cuam lub neej 2 xyoos)
Kev xaiv: Xaiv qhov ntsuas kub ntawm analog lossis digital thiab ntsuas cov av noo nrog qhov tseeb ntawm ± 5% RH;
Kev teeb tsa: Txuas rau sab hauv vaj huam sib luag (tsis yog- qhov chaw nyob) lossis lub qhov rooj ntawm lub txee hloov pauv- suav nroggas insulated substation gisauxiliary txee- nyob rau hauv ib qho chaw yooj yim pom rau kev saib xyuas;
Interpretation: The green zone (RH) indicates safe conditions; the yellow zone (65%–80% RH) requires increased monitoring; the red zone (>80% RH) yuav tsum tau ntsuas tam sim dehumidification.
Txhim kho Basic Sealing: Siv hluav taws kub- tiv thaiv putty los kaw cov kab nkag hauv lub qhov thiab lub txee qhov khoob (tseem ceeb rau kev tiv thaiv kom tsis txhob ya rawsgis circuit breakercov ntaub thaiv npog); Hloov cov hnub qub txee qhov rooj gaskets (kom muaj qhov compression ntawm 5-8 mm) los thaiv txoj hauv kev rau kev nkag mus rau sab nraud. Qhov kev ntsuas yooj yim no ua haujlwm rau ob qho tib si standard switchgear thiabgis roj insulated switchgearauxiliary cov qauv.
Kev daws teeb meem: Nres Switchgear Condensation ntawm Qhov Chaw
Rau cov haujlwm tshiab, qhov hloov pauv tseem ceeb, lossis siab - qhov chaw noo noo, txoj hauv kev zoo tshaj plaws los kho cov condensation yogCov cuab yeej siv tshawb fawb xaiv + qhov chaw dehumidification. Dehumidifiers yog cov cuab yeej tseem ceeb. Ua raws li qhov yooj yim no "4-kauj ruam xaiv txoj kev" kom tsis txhob poob peev. Ua ke nrog cov qauv me me hloov pauv rau kev tiv thaiv tag nrho.
Kauj Ruam 1: Xam Dehumidification Capacity (Limplified)
Siv cov qauv yooj yim los nrhiav qhov loj dehumidifier:
Dehumidification muaj peev xwm (L/hnub)=Switchgear ntim (m³) × 1.2 × Humidity txawv × 24
Piv txwv: A 1.5m³ 10kV switchgear (1.2m × 0.8m × 1.6m) xav tau lub tshuab dehumidifier nrog Ntau dua lossis sib npaug ntawm 0.6L / hnub muaj peev xwm (ntawm 80% mus rau 60% av noo).
Cov lus qhia ntxiv: Ntxiv 20% muaj peev xwm ntxiv rau lub caij los nag lossis cua sov- tsim cov khoom siv.

4. Cov ntaub ntawv-Kev khaws cia: Sau cov ntaub ntawv kub thiab av noo, dehumidifier kev ua haujlwm, thiab cov ntaub ntawv khaws cia / hloov pauv; tsim cov ntaub ntawv kho mob ntawm cov khoom siv.
Xaus: Kev tiv thaiv condensation yog qhov tseem ceeb tshaj li kev kho
Qhov teeb meem condensation thiab noo noo nyob rau hauv lub txee hloov tsis yog ib qho kev sib tw insurmountable. Qhov tseem ceeb yog nyob rau hauv "kev kuaj mob kom raug + kev xaiv kev tshawb fawb + kev ua haujlwm thiab kev saib xyuas". Tus nqi qis - kev daws teeb meem tuaj yeem tswj tau sai sai, cov cuab yeej ua haujlwm dehumidification thiab kev txhim kho cov txheej txheem tuaj yeem txiav tawm cov txheej txheem condensation ntawm lub hauv paus, thiab kev ua haujlwm ntse thiab kev saib xyuas muab kev lav phib xaub rau kev ua haujlwm ntev -. Los ntawm kev ua raws li lub hauv paus ntsiab lus ntawm "saib xyuas thawj zaug, kev tswj hwm hierarchical, thiab hais txog ob qho tib si cov tsos mob thiab cov hauv paus ntsiab lus", tsis tsuas yog cov cuab yeej ua tsis tiav los ntawm kev sib xyaw ua ke, tab sis kuj tseem tuaj yeem zam lub neej kev pab cuam lub neej ntawm cov khoom hloov pauv mus txog 3-5 xyoo, thiab cov nqi khiav lag luam thiab kev saib xyuas tuaj yeem txo qis.
