Shenhai Explosion-Proof
Hauv kev siv hluav taws xob tawg, Cov ntaub ntawv rwb thaiv tsev yog sib txawv rau hauv cov khoom thiab cov kua, tsim tshwj xeeb rau cov ntawv thov no, tsis zoo li cov rwb thaiv tsev dav dav.
Khoom siv rwb thaiv tsev
hu ua “solid-state rwb thaiv tsev cov ntaub ntawv,” cov no yog cov khoom uas nyob twj ywm nyob rau hauv kev ua hauj lwm tej yam kev mob. Pawg no suav nrog cov ntaub ntawv zoo li cov kua roj vanish, uas yog pib ua kua tab sis solidify thaum thov.
Feem ntau siv cov khoom siv rwb thaiv tsev hauv cov khoom siv hluav taws xob tawg tau teev tseg hauv qab no.
| Cov ntaub ntawv qib | Muab piv rau Kev Ntsuas Kev Ntsuas (CTI) | Khoom npe |
|---|---|---|
| Kuv | 600≤ CTI | Ceramics (glazed), mica, iav |
| II | 400≤ CTI 600 | Melamine asbestos arc yas, silicone organic asbestos arc resistant yas, unsaturated polyester aggregate |
| III- ib | 175≤ CTI＜400 | Polytetrafluoroethylene yas, melamine iav fiber ntau yas, epoxy iav ntaub board kho nrog arc resistant xim rau ntawm qhov chaw |
| III- ib | 100≤ CTI＜175 | Phenolic yas |
Cov ntaub ntawv no tau muab qhab nia raws li lawv qhov Kev Sib Piv Kev Ntsuas Ntsuas (CTI), ib qho kev ntsuas ntawm superficial hluav taws xob kev ua tau zoo. Txawm li cas los, lawv mechanical, thermal, thiab cov khoom siv tshuaj lom neeg tuaj yeem sib txawv heev, yuav tsum tau ceev faj xaiv raws li tej yam kev mob ntawm kev siv, suav nrog kev txiav txim siab rau lub zog siv tshuab, kub tsis kam, thiab chemical durability.
Ceramic (Glazed) Khoom siv
Inorganic non-metallic rwb thaiv tsev cov khoom, cov no yog tsim los ntawm sintering hlau oxides thiab tsis-oxygen hlau tebchaw. Lawv cov cwj pwm muaj xws li hardness ntau ntawm 1000 ~ 5000HV, tensile zog ntawm 26 ~ 36 MPa, compressive zog ntawm 460 ~ 680 MPa, melting point tshaj 2000 ° C, Tsawg thermal expansion, thiab siab tshuaj stability thiab tsis kam mus corrosion.
Polytetrafluoroethylene (PTFE)
Cov khoom siv fluoroplastic no txhawb nqa kev siv mus sij hawm ntev thoob plaws qhov kub ntawm -180 ° C txog 260 ° C. Nws yog chemically ruaj khov, resistant rau corrosion, Nws muaj qhov sib txhuam coefficient tsawg, thiab muaj qhov tseem ceeb thermal expansion coefficient.
Phenolic yas
Ib lub thermosetting yas, paub coj mus muag li “bakelite” los yog “phenolic pawg thawj coj saib,” Nws tuaj yeem tiv taus qhov kub siab tshaj 3000 ° C thiab muaj kev kub hnyiab zoo thiab kev ruaj ntseg tshuaj, Txawm hais tias nws yog nkig thiab tsis tiv taus alkali corrosion.
Ntxiv nrog rau cov khoom siv rwb thaiv tsev hais, Cov khoom siv hluav taws xob tawg-pov thawj feem ntau siv ntau yam khoom siv insulating, suav nrog cov ntaub ntawv yas rau cov khoom siv insulating thiab qee yam khoom siv hauv cov khoom tawg-pov thawj.
Cov khoom siv hluav taws xob ua kua
Cov no xa mus rau cov khoom insulating feem ntau pom hauv cov kua dej, zoo li transformer roj, thiab cov ntaub ntawv zoo li insulating kua roj vanish siv rau coil impregnation, uas solidify tom qab kev kho mob tshwj xeeb tseem tseem suav hais tias yog kua insulators.
1. Transformer Roj
• Qhov tseem ceeb rau cov khoom siv hluav taws xob tawg xws li transformers, cov roj no yuav tsum ua raws li cov qauv tshwj xeeb:
• Ignition point tsis qis dua 300 ° C.
• Flash point tsis qis dua 200 ° C (khob kaw).
• Kinematic viscosity tsis tshaj 1*10?? m² / s ntawm 25 ° C.
• Dielectric tawg zog tsawg kawg yog 27kV.
• Volume resistivity tsawg kawg 1*10??? m ntawm 25 ° C.
• Ncuav qhov taw tes tsis tshaj -30 ° C.
• Acidity (neutralization nqi) mus txog 0.03 mg/g (poov tshuaj hydroxide).
Transformer roj, Feem ntau cov ntxhia insulating roj muaj alkanes, cycloalkanes, thiab unsaturated aromatic hydrocarbons, muaj zoo heev insulating zoo thiab aging stability. Txawm li cas los, nws siv nyob rau hauv Class I mining khoom raug txwv vim muaj peev xwm degradation ntawm nws cov khoom insulating dhau siv ntev.
2. kua roj vanish
Siv rau impregnating hluav taws xob coils hauv cov khoom tawg-pov thawj, insulating kua roj vanish txhim kho lawv cov hluav taws xob rwb thaiv tsev muaj peev xwm. Muaj nyob rau hauv cov kuab tshuaj raws li hnyav thiab hnyav-dawb cov ntaub ntawv, Cov kua roj vanish no yog tsim los ntawm ntuj lossis hluavtaws cob ua ke nrog ntau yam kuab tshuaj xws li benzene thiab cawv rau hom hnyav raws li, thiab hluavtaws resins, solidifying agents, thiab active thinners xws li styrene rau hom hnyav-dawb.
Ob hom kua roj vanish muaj ntau txoj kev xaiv kom haum rau cov ntawv thov sib txawv, kom ntseeg tau tias adaptability rau tej yam uas yuav tsum tau ua.
