High -voltage switchgearyog ib qho tseem ceeb ntawm cov khoom siv hauv lub zog hluav taws xob, thiab nws cov kev ua haujlwm rwb thaiv tsev ncaj qha cuam tshuam rau kev ua haujlwm ruaj ntseg thiab ruaj khov ntawm daim phiaj hluav taws xob. Hom rwb thaiv tsev txhaum hom, ua rau, thiab qhov tshwm sim yog raws li nram no:
Luv luv
Cov tsiaj me xws li nab thiab nas tuaj yeem nkag mus rau qhov hloov pauv los ntawm qhov hauv cov kab hauv kab, ua rau kev sib txuas ntawm cov busbars lossis busbars hauv lub switchgear thiab ua rau theem - mus rau -theem lossis ib zaug -theem- rau - hauv av luv luv circuits. Qhov no tuaj yeem ua rau lub switchgear mus ncig thiab poob lub zog, cuam tshuam rau kev ua haujlwm nyab xeeb ntawm daim phiaj hluav taws xob.
Moisture thiab Surface Contamination ntawm Insulating Cheebtsam
Lub switchgear muaj ntau yam insulating uas ua los ntawm epoxy resin (xws li bushings, transformers, post insulators, thiab lwm yam). Vim tias cov khoom siv nws tus kheej tsis raug kaw tag nrho, nws cov dej noo thiab kev sib kis tsis zoo. Tsis tas li ntawd, epoxy resin yog nquag nqus dej. Nyob rau hauv cov huab cua los nag nrog high humidity, noo noo nyob rau saum npoo ntawm lub insulating Cheebtsam yuav nkag mus sai sai rau hauv lub sab hauv ntawm lub Cheebtsam nyob rau hauv lub zog ntawm ib tug hluav taws xob teb, ua rau ib tug tseem ceeb txo nyob rau hauv rwb thaiv tsev tiv thaiv thiab ib tug nce nyob rau hauv qhov dej ntws tam sim no, uas yuav ua rau corona los yog arc paug, raws li qhia nyob rau hauv daim duab 1, qhov twg theem - mus rau -theem insulating tivthaiv tshwm sim.
Tsis txaus hluav taws xob kev nyab xeeb nrug
Kev txheeb xyuas ntawm cov teeb meem kev tiv thaiv hluav taws xob hloov hluav taws xob tau qhia txog qhov teeb meem tshwm sim: tsis txaus theem sib nrug. Noj KYN61 series 35 kV switchgear ua piv txwv, kev ntsuas tau pom qhov kev ncua deb ntawm peb -theem txav cov neeg sib cuag yog 250 hli, thiab qhov siab tshaj plaws nyob deb ntawm peb - theem coj yog 295 mm. Cov huab cua tshem tawm ntawm theem thiab nruab nrab ntawm theem thiab hauv av tsis txaus, ua tsis tau raws li qhov yuav tsum tau muaj tsawg kawg yog 300 hli rau kev tshem tawm hluav taws xob sab hauv tsev raws li tau teev tseg hauv "Kaum Yim Hli Kev Tiv Thaiv Kev Nyab Xeeb Loj ntawm Lub Xeev Grid Corporation ntawm Tuam Tshoj".
High - cov khoom siv hluav taws xob tawm los ntawm cov khoom siv insulating
Txhawm rau txo qhov hloov pauv loj thiab cov nqi tsim khoom, cov tuam txhab feem ntau ntxiv cov epoxy resin los yog SMC insulating baffle ntawm theem los hloov cov hluav taws xob xa hluav taws xob thiab txhim kho cov rwb thaiv tsev interphase. Txawm li cas los xij, qhov no tsis yog qhov tseem ceeb txhim kho lub switchgear lub rwb thaiv tsev qauv. High humidity theem nyob rau hauv lub switchgear ua rau cov plua plav thiab ya raws. Ua ke nrog cov dej noo-absorbing cov khoom ntawm epoxy resin los yog SMC insulating baffle, nyob rau hauv ntev - lub sij hawm fais fab zaus voltage, qhov no yuav ua rau kom muaj feem cuam tshuam, ua rau lub deterioration ntawm ib puag ncig rwb thaiv tsev ntaub ntawv. Qhov kev rwb thaiv tsev tsis zoo no cuam tshuam rau thaj chaw hluav taws xob nyob ib puag ncig, tsim kom muaj lub voj voog tsis zoo uas maj mam tsim cov kab hluav taws xob, thaum kawg ua rau muaj xwm txheej.
Circuit Court breaker tiv tauj tawm
Circuit Court breaker txav thiab nyob ruaj khov tiv thaiv tawm yog feem ntau tshwm sim los ntawm kev sib cuag tsis zoo ntawm kev txav mus los thiab nyob ruaj khov. Tiv tauj hnav, tshem tawm, xeb, xeb, lossis tsis txaus tso ntawm qhov kev sib cuag tuaj yeem cuam tshuam loj rau kev sib cuag ntawm cov neeg sib cuag. Kev tiv thaiv ntau dhau tuaj yeem ua rau cov neeg sib cuag kom sov, thiab tseem ua rau lub txee hloov mus hlawv thiab tawg. Daim duab 2 qhia txog qhov tshwm sim tawm ntawm qhov chaw ntawm lub thawv ntim khoom.
Busbar rau Bushing Discharge
Laus switchgear siv bushings yam tsis muaj shielding tsim, ua rau muaj qhov sib txawv ntawm busbar thiab bushing. Lub bushing thiab busbar tsis yog tib lub peev xwm. Tom qab lub switchgear tau ua haujlwm rau lub sijhawm, lub bushing (epoxy resin) absorbs noo noo, txo nws cov rwb thaiv tsev kev ua haujlwm. Qhov no ua rau muaj kev tso tawm ib nrab ntawm qhov khoob me me (raws li qhia hauv daim duab 3), cuam tshuam loj rau kev ua haujlwm nyab xeeb ntawm daim phiaj hluav taws xob.
Kev txhim kho thiab kev tsim kho tsis zoo
Kev tsis sib haum xeeb ntawm cov khoom siv hauv lub tshuab hloov pauv thiab tsis yog - ua raws li cov kev qhia tshwj xeeb ntawm kev teeb tsa kuj tseem yog yam tseem ceeb uas ua rau muaj kev sib tsoo switchgear, feem ntau tshwm sim hauv cov hauv qab no:
(1) Txawm hais tias cov busbars thiab cov khoom nyob rau hauv lub txee tau chamfered, tseem muaj cov npoo ntse thiab burrs, uas tuaj yeem yooj yim tsim ib qho hluav taws xob tsis sib xws, yog li ua rau cov ntsiab lus tawm;
(2) Lub bolts ntawm lub busbar txuas ntev dhau lawm;
(3) Lub insulating rods kho cov insulating baffles tsis ntsia raws li specifications thiab nyob ze rau cov busbars, ua rau paug.

Cov ntsiab lus
Rwb thaiv tsev faults nyob rau hauv siab -voltage switchgear feem ntau tshwm sim los ntawm kev sib txuas ntawm ntau yam cuam tshuam nrog hluav taws xob, cua sov, thiab ib puag ncig. Kev tiv thaiv zoo dua li kho. Nws raug nquahu kom tsom mus rau peb qhov kev pheej hmoo tseem ceeb ntawm kev tso tawm ib nrab, av noo, thiab cov pa phem los ntawm kev saib xyuas online ua ke nrog kev saib xyuas tsis tu ncua, thiab nruj me ntsis tswj cov khoom xaiv, txheej txheem installation, thiab kev tswj ib puag ncig. Rau cov cuab yeej qub, kev txhim kho rwb thaiv tsev lossis kev hloov pauv tuaj yeem ua tiav maj mam txhawm rau txhim kho kev ntseeg tau tag nrho.
Shaanxi Huadian siv siab -lub zog, arc-resistant, thiab creepage-resistant tshwj xeeb epoxy resin thiab cov ntaub ntawv rwb thaiv tsev, nrog rwb thaiv tsev ua tau zoo tshaj lub teb chaws tus qauv. Cov txheej txheem tsim khoom nruj thiab kev hloov pauv ib puag ncig txhais tau hais tias xaiv Shaanxi Huadian txhais tau tias xaiv tsis yog lub tshuab hluav taws xob nkaus xwb, tab sis kev tswj hwm kev tiv thaiv kev noj qab haus huv uas npog tag nrho cov cuab yeej siv lub neej.
