Taw qhia: Qhov tseem ceeb ntawm Mica hauv hluav taws xob rwb thaiv tsev
Nyob rau hauv niaj hnub hluav taws xob thiab hluav taws xob systems,kev nyab xeeb thiab efficiencynyob ntawm qhov zoo ntawm cov ntaub ntawv rwb thaiv tsev. Ib qho ntawm cov ntaub ntawv ntseeg siab tshaj plaws thoob ntiaj teb yogmica.Renowned rau nwsTshwj xeeb dielectric zog, kub tsis kam, thiab mechanical stability, mica plays lub luag haujlwm tseem ceeb hauv kev tiv thaiv hluav taws xob los ntawm kev ua tsis tiav thiab kev puas tsuaj.
Kab lus no tshawb txog qhovkev ua haujlwm ntawm mica hauv hluav taws xob rwb thaiv tsev tshuab, nws qhov zoo, thiab vim li cas nws tseem siv dav hauv txhua yam los ntawm siab -voltage machinery mus rau cov khoom siv hauv tsev.
Mica yog dab tsi?
Mica yog ib pab pawg ntawm ib txwm tshwm simsilicate mineralsuas tuaj yeem muab faib ua nyias, hloov tau yooj yim.Nws yog cov tshuaj ruaj khov, tsis yog -combustible, thiab muaj cov khoom siv hluav taws xob zoo thiab thermal rwb thaiv tsev.Cov yam ntxwv no ua rau mica zoo tagnrho rau insulating conductors, windings, thiab cov khoom uas yuav tsum tau tiv taus.high voltages, kub heev, thiab mechanical stress.
Kev ua haujlwm ntawm Mica hauv Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob
1. High Dielectric zog
Ib qho ntawm mica lub luag haujlwm tseem ceeb tshaj plaws yog nwsmuaj peev xwm tiv thaiv hluav taws xob tawg.Nrog lub zog dielectric ntau tshaj100 kV / hli, mica yog zoo kawg nkaus haum rau cov ntaub ntawv rwb thaiv tsev raug rau cov hluav taws xob muaj zog.
Tiv thaiv kev luv luv hauv cov khoom siv hluav taws xob siab -
Ua kom lub sijhawm ntev - kev cia siab rau hauv transformers, motors, thiab generators
Muab cov rwb thaiv tsev ruaj khov txawm tias nyob hauv cov av ntub lossis siab - qhov kub thiab txias
2. Thaum tshav kub kub tsis kam
Tsis zoo li ntau cov ntaub ntawv pov thawj organic, mica tiv taus qhov kub thiab txiasmus txog 500-600 degreetsis muaj kev ua tau zoo degradation.Qhov no ua rau nws indispensable nyob rau hauv:
Fais motors uas ua kom muaj cua sov tseem ceeb thaum ua haujlwm
Generators thiab turbines tsis tu ncua raug rau qhov kub thiab txias
Cov khoom siv hauv tsev xws li toasters, hair dryers, thiab heaters
3. Mechanical Strength thiab Flexibility
Mica yog ob qho tib simechanically ruaj khov thiab hloov tauthaum tsim los rau hauv cov ntawv los yog tapes.Qhov no dual tus yam ntxwv ua kom rwb thaiv tsev tuaj yeem:
Tiv thaiv kev vibration thiab mechanical stress nyob rau hauv rotating machinery
Ua rau hauv qhov rwb thaiv tsev, hauv av- phab ntsa rwb thaiv tsev, thiab coil qhwv
Khaws cov duab thiab adhesion txawm nyob rau hauv thermal cycling
4. Hluav taws kub tsis kam thiab Arc Resistance
Mica yogtsis yog -combustible thiab resistant rau arc puas, txhais tau tias nws tiv taus qhov hluav taws xob tam sim ntawd lossis hluav taws xob tsis raug cai yam tsis muaj teeb meem.Qhov no yog qhov tseem ceeb hauv:
Hluav taws kub- cov kab hluav taws xob tiv taus siv hauv cov tsev thiab chaw ua haujlwm
Hluav taws xob switchgear raug rau arcing tej yam kev mob
Kev nyab xeeb- cov ntawv thov tseem ceeb xws li aerospace thiab kev tiv thaiv kab mob
5. Tsawg Dielectric poob
Mica nthuav tawmTsawg dielectric poob (tan δ), lub ntsiab lus nws dissipates yuav luag tsis muaj zog li cua sov nyob rau hauv alternating hluav taws xob teb.Qhov no yog tshwj xeeb tshaj yog tseem ceeb nyob rau hauv:
High - zaus circuits xws li xov tooj cua transmitters
Precision capacitors xav tau ntev -lub sij hawm stability
Zog- siv hluav taws xob zoo
6. Tshuaj thiab Environmental Stability
Mica yog chemically inert thiab resistant rau ya raws, acids, thiab alkalis.Nws tseem muaj kev ntseeg siab nyob rau hauv sab nraum zoov thiab kev lag luam ib puag ncig uas lwm cov ntaub ntawv rwb thaiv tsev yuav degrade.
7. Kev nyab xeeb thiab kev pabcuam lub neej
Los ntawm kev sib xyaw dielectric zog, kub tsis kam, thiab nplaim retardancy, mica xyuas kom meejLub neej ua haujlwm ntev rau cov khoom siv hluav taws xob.Qhov no txo cov nqi txij nkawm thiab txhim kho tag nrho cov kev ntseeg tau.
Kev siv Mica hauv hluav taws xob rwb thaiv tsev
ib. Rotating Machinery
Qhov rwb thaiv tsev, hauv av- rwb thaiv tsev phab ntsa, thiab coil wrapping nyob rau hauv siab -voltage motors thiab generatorsensure stability tiv thaiv kev co thiab kev khiav hauj lwm kub.
b. Hloov pauv
Mica-raws li cov ntaub ntawv sib xyaw tiv thaiv windings los ntawm kev tso tawm ib nrab thiab kub dhau, txhim kho kev ua haujlwm thiab kev ntseeg siab hauv cov tshuab hluav taws xob.
c. Capacitors
Nyias mica films pab asdielectric txheej nyob rau hauv siab -precision capacitors, muab lub sij hawm ntev - stability thiab tsawg zog poob.
d. Hluav taws kub-Resistant Cables
Mica daim kab xev yog qhwv ib ncig ntawm cov conductors kom muaj kev ruaj ntseg hauv Circuit Court thaum hluav taws kub.Widely siv nyob rau hauv: lub tsev thaiv, muaj nroj tsuag, thiab tsheb thauj mus los systems.
e. Cov khoom siv hauv tsev
Siv nyob rau hauv cov cua kub, toasters, plaub hau tshuab, thiab microwave ncu.Muab ob qho tib sithermal thiab hluav taws xob rwb thaiv tsev.
