Condensation - Qhov Risk zais rau Switchgear

Ib lub chaw cog qoob loo ntawm ntug dej hiav txwv raug kev txom nyem $ 100k + poob vim 10kV switchgear condensation: busbar insulator creepage ua rau theem - mus rau -theem luv luv Circuit Court, kaw lawm ntau 3 hnub. Qhov no tshwm sim nyob rau hauv cov cheeb tsam humid, lub caij los nag, los yog underground substations -tshwj xeeb tshaj yog rau33kV AIS TSO, 33kV GIS hloov, thiabswitchgear hlau cladtshuab. Fogged iav, dej tee rau ntawm tooj liab tuav, thiab cov rwb thaiv tsev moist yuav zoo li tsis tseem ceeb, tab sis lawv ua rau cov rwb thaiv tsev tawg, hlau corrosion, thiab cov txheej txheem jamming. Raws li ISO 9001 tau lees paub cov kev daws teeb meem hluav taws xob nrog 17 xyoo ntawm kev paub thoob ntiaj teb, Zhejiang Lvma Electric Co., Ltd. (LVMA) integrates ya raws -cov ntaub ntawv pov thawj tsim rau hauv peb transformer txhawb kev daws teeb meem rau kev lag luam xws li Europe, Middle East, thiab Southeast Asia.

I. Qhov Tseem Ceeb Ua rau Condensation

Condensation forms thaum huab cua kub poob qis dua qhov dej lwg, uas tau tsav los ntawm ob yam tseem ceeb:

Sab nraud Factors: High humidity (>85% RH), day-night temperature differences (>10 degree), thiab qhov cua tsis zoo - teeb meem tseem ceeb rau33kV GIS hloov's kaw qauv thiab33kV AIS TSOnyob rau hauv qhov chaw sab nraum zoov.

Internal Flaws: Kev sib khi tsis txaus (cov roj hmab laus, cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob

LVMA's R&D pab neeg, coj los ntawm Mr. Ye Jinfei (ib tug 40- xyoo qub qub nyob rau hauv Tuam Tshoj tus qauv GB), siv cov kev nkag siab zoo li no los ua kom zoo dua peb cov kev soj ntsuam ntse, txo cov cuab yeej hla kev ya raws.

II. Kev phom sij ntawm cov dej noo

Rwb thaiv tsev tsis ua haujlwm: Cov yeeb yaj kiab dej ua rau muaj kev nkag siab thiab luv luv, tshwj xeeb tshaj yog txaus ntshai rau idle 33kV AIS switchgear thaum rov-commissioning.

Hlau corrosion: xeb puas terminals thiab kev khiav hauj lwm mechanisms, txaus ntshai hloov tsis ua hauj lwm nyob rau hauvswitchgear hlau cladtshuab.

Kev txo qis ntawm lub neej: Damp switchgear (xws li 33kV GIS switchgear) poob 3-5 xyoo ntawm kev pab cuam lub neej, nrog 40% tus nqi kho dua.

III. Tswv yim daws rau Condensation

(1) Tsawg-Cov nqi kho mob xwm txheej ceev (tsis muaj hluav taws xob tawm)

Hnab Desiccant: Dai 1-2 lub hnab calcium chloride rau ib lub tshuab hloov pauv (tus nqi ≈ $ 3 / xyoo) kom nqus dej noo.

Kev txhim kho kev sib khi: Siv cov av nkos fireproof rau qhov khoob thiab hloov cov gaskets (kom paub meej 5-8mm compression).

Kub-cov av nplaum nplaum: Saib xyuas hauv lub sijhawm (ntsuab =<65% RH safe; red = >80% RH ceev).

(2) Cov hauv paus kev tshaj lij-Ua rau kev daws teeb meem

Kev xaiv dehumidifier:

Cov Lus Qhia Tseem Ceeb: Xaiv IP54+ tiv thaiv, tsis siv neeg tso dej, thiab qis- qauv ntsuas kub (-10-40 degree) rau thaj chaw txias.

Kev hloov kho cov qauv: Ntxiv cov qhov dej hauv qab thiab nruab cov cua sov ua ke- cov khoom siv cua.

IV. LVMA's Support

Nrog 40+ patents thiab cov peev txheej tsim tawm digital, LVMA hloov zuj zus los ntawm cov chaw tsim khoom hloov pauv mus rau ntsuab, ntse hluav taws xob daws teeb meem. Peb muab cov khoom ua kom haum rau cov dej noo- pov thawj cov lus qhia rau cov neeg siv khoom thoob ntiaj teb, ua raws li peb txoj kev cog lus rau kev ntseeg siab thiab kev nyab xeeb.
