Hybrid rwb thaiv tsev cov ntaub ntawv yog ntau yam molded rwb thaiv tsev cov ntaub ntawv los ntawm kev ua cov saum toj no ob cov ntaub ntawv, thiab yog siv los ua lub hauv paus, plhaub, thiab lwm yam ntawm cov khoom siv hluav taws xob.
Kev siv cov khoom siv rwb thaiv tsev
Kev ua haujlwm ntawm cov ntaub ntawv insulating yog cais cov khoom nyob nrog cov peev txheej sib txawv hauv cov khoom siv hluav taws xob. Yog li ntawd, cov khoom siv rwb thaiv tsev yuav tsum xub muaj cov rwb thaiv tsev siab thiab tiv taus lub zog hluav taws xob, thiab tsis txhob muaj xwm txheej xws li xau thiab tawg. Thib ob, cov cua sov ua haujlwm yuav tsum ua kom zoo kom tsis txhob muaj kev laus thiab kev ua kom tsis zoo vim lub sijhawm ntev overheating; Tsis tas li ntawd, nws yuav tsum muaj cov yam ntxwv ntawm cov thermal conductivity zoo, noo noo tsis kam thiab xob laim, siab mechanical zog thiab yooj yim ua. Raws li qhov yuav tsum tau ua ntawm cov lus piav qhia, cov ntsuas kev ua tau zoo ntawm cov khoom siv rwb thaiv tsev feem ntau suav nrog lub zog dielectric, lub zog tensile, lub ntiajteb txawj nqus, nthuav coefficient, thiab lwm yam.
Rwb thaiv tsev tiv thaiv lub zog hluav taws xob: qhov siab dua qhov hluav taws xob siv ntawm ob qho kawg ntawm lub rwb thaiv tsev, qhov ntau dua qhov hluav taws xob hluav taws xob ntawm cov khoom siv, thiab qhov ntau dua nws yog ionize kev sib tsoo, ua rau cov rwb thaiv tsev tawg. Qhov tsawg kawg nkaus qhov hluav taws xob uas tawg ib qho hluav taws xob yog hu ua qhov hluav taws xob tawg ntawm qhov hluav taws xob no. Thaum cov khoom siv rwb thaiv tsev 1 hli tuab tawg, qhov hluav taws xob kilovolts uas yuav tsum tau ntxiv yog hu ua cov rwb thaiv tsev tiv thaiv hluav taws xob ntawm cov khoom siv rwb thaiv tsev, hu ua lub zog rwb thaiv tsev. Vim tias cov ntaub ntawv insulating muaj qee lub zog dielectric, txhua yam khoom siv hluav taws xob, txhua yam khoom siv kev nyab xeeb (hluav taws xob pliers, hluav taws xob cwj mem, insulating hnab looj tes, insulating rods, thiab lwm yam), ntau yam khoom siv hluav taws xob, cov chaw tsim khoom tau teev tseg ib qho kev tso cai voltage, hu ua rated voltage. Qhov voltage nws raug rau thaum siv yuav tsum tsis txhob tshaj nws qhov ntsuas voltage tus nqi kom tsis txhob muaj xwm txheej.
Lub zog tensile: Lub zog tensile uas cov khoom siv rwb thaiv tsev tuaj yeem tiv taus ib qho chaw hla ntu ntu, piv txwv li, iav tuaj yeem tiv taus lub zog tensile ntawm 1400 Newtons ib square centimeter ntawm cheeb tsam cross-sectional.
Lub rwb thaiv tsev ntawm cov ntaub ntawv insulating yog ze ze rau qhov kub thiab txias. Qhov siab dua qhov kub, qhov tsis zoo ntawm cov khoom siv hluav taws xob ntawm cov khoom siv insulating. Txhawm rau kom ntseeg tau tias lub zog dielectric, txhua cov khoom siv rwb thaiv tsev muaj qhov tsim nyog siab tshaj plaws kev ua haujlwm kub, hauv qab no uas nws tuaj yeem siv tau ntev ntev, tshaj qhov nws yuav muaj hnub nyoog sai. Raws li qib ntawm kev tiv thaiv tshav kub, cov ntaub ntawv rwb thaiv tsev tau muab faib ua Y, A, E, B, F, H, C thiab lwm qib. Piv txwv li, qhov siab tshaj plaws kev ua haujlwm kub ntawm Class A rwb thaiv tsev cov ntaub ntawv yog 105 degree, thiab feem ntau ntawm cov ntaub ntawv rwb thaiv tsev nyob rau hauv tis transformers thiab motors feem ntau siv rau Class A.
Nqe Lus Nug 4: Kev rwb thaiv tsev yog dab tsi? Cov ntaub ntawv uas tsis siv hluav taws xob yog hu ua cov ntaub ntawv insulating
Nqe Lus Nug 5: Cov khoom siv dab tsi yog cov hluav taws xob rwb thaiv tsev ua los ntawm Raws li kev siv sib txawv ntawm cov rwb thaiv tsev, cov ntaub ntawv sib txawv yog siv. Piv txwv li: polyvinyl chloride board, epoxy resin board, ntawv offset phaj, daim ntaub roj hmab phaj, bakelite board, ntau yam resin boards... Tos.
Nqe Lus Nug 6: Dab tsi yog pawg ntawm cov khoom siv rwb thaiv tsev feem ntau Cov khoom siv rwb thaiv tsev yog cov khoom siv hluav taws xob rwb thaiv tsev.

Thib rau, cov khoom siv hluav taws xob rwb thaiv tsev tuaj yeem ua raws li qhov loj me (thickness. Diameter. length. width, etc.), cov specifications muab faib ua ntau yam.
Nqe Lus Nug 7: Cov khoom siv rwb thaiv tsev zoo tshaj plaws yog dab tsi? Cov khoom siv hluav taws xob zoo lossis thermal rwb thaiv tsev. Cov ntaub ntawv thermal rwb thaiv tsev kuj tseem hu ua cov ntaub ntawv thermal rwb thaiv tsev. Cov ntaub ntawv rwb thaiv tsev feem ntau xa mus rau cov khoom siv hluav taws xob insulating, thiab lawv cov conductivity yog li ntawm 10-10 sab hnub poob / meter hauv qab no. Raws li kev xav tau ntawm cov khoom siv hluav taws xob sib txawv, nws kuj ua lub luag haujlwm ntawm lub zog cia, cua sov dissipation, txias, arc extinguishing, ya raws-pov thawj, mildew-proof, anti-corrosion, anti-irradiation, mechanical support thiab fixation, thiab kev tiv thaiv ntawm tus thawj coj.
Cov khoom siv rwb thaiv tsev ntxov tshaj plaws yog paj rwb, txhob lo lo ntxhuav, mica, roj hmab thiab lwm yam khoom ntuj tsim. Tom qab 30s ntawm lub xyoo pua 20th, cov khoom siv hluav taws xob hluavtaws tsim tau sai heev, thiab ntau yam khoom siv hluavtaws, plastics, thiab lwm yam tau ua tiav hauv kev tsim hluav taws xob engineering los tsim cov motors thiab cov khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob, kom lub peev xwm ntawm cov khoom siv hluav taws xob. txuas ntxiv nthuav dav thiab qhov ntim tau maj mam txo qis, yog li txhawb kev txhim kho cov khoom siv hluav taws xob thiab hluav taws xob.
Cov ntaub ntawv rwb thaiv tsev, muab faib ua roj, kua thiab khoom 3 pawg.
Gas insulating cov ntaub ntawv muaj siab ionization teb lub zog thiab lub zog tawg, tuaj yeem rov qab ua haujlwm rwb thaiv tsev sai sai tom qab tawg, tshuaj lom neeg ruaj khov, tsis muaj hluav taws kub, tsis tawg, tsis muaj kev laus, tsis muaj corrosive, tsis yooj yim rau decomposed los ntawm paug, thiab loj tshwj xeeb tshav kub muaj peev xwm, zoo thermal conductivity thiab fluidity. Cua yog cov khoom siv hluav taws xob ntau tshaj plaws. Piv txwv li, lub overhead conductors ntawm AC thiab DC kis tau tus mob kab, thiab cov overhead conductors yog insulated los ntawm huab cua. High-voltage standard capacitors kuj siv roj-insulated xov xwm, thiab nyob rau hauv thaum ntxov hnub, high-pressure nitrogen los yog carbon dioxide tau siv, thiab sulfur hexafluoride (SF6) yog tam sim no siv. SF6 kuj tseem siv rau hauv kev tsim cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob, cov hlau txuas hluav taws xob sib txuas, cov roj hluav taws xob hluav taws xob xa hluav taws xob thiab cov roj hluav taws xob hluav taws xob.
Cov ntaub ntawv insulating kua kuj hu ua roj insulating. Sau cov voids sab hauv lossis nruab nrab ntawm cov ncej ntawm cov khoom siv los txhim kho lawv cov khoom dielectric thiab txhim kho lub peev xwm ntawm cov cua sov ntawm cov cuab yeej. Cov khoom siv rwb thaiv tsev ua kua muaj lub zog tawg siab, me me dielectric poob tangent (tgσ), siab rwb thaiv tsev resistivity, thiab me me txheeb ze permittivity. Tsis tas li ntawd, nws kuj muaj lub cev thiab tshuaj lom neeg zoo heev, xws li kub gasification, siab flash point, tsis tshua muaj khov point, loj thermal conductivity, zoo thermal stability, thiab me me inspiration nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb. Raws li nws cov polarity, nws muab faib ua plaub pawg: polarity tsis muaj zog, tsis muaj polarity, polarity thiab muaj zog polarity. Raws li lub hauv paus ntawm cov ntaub ntawv, nws muab faib ua peb pawg: ntxhia insulating roj, hluavtaws insulating roj thiab zaub roj. Mineral insulating roj, hu ua ntxhia roj, yog refined los ntawm roj av thiab belongs rau ib tug weakly polar nruab nrab. Nws tus txheeb ze permittivity yog hais txog 2.2, thiab qhov tawg voltage hauv tus qauv electrode yog 35 ~ 50 kilovolts (kV). Lub teeb nyem yog 125 ~ 135 degree, uas yog siv los tsim cov transformers, cables, capacitors, thiab lwm yam. Synthetic insulating roj yog cov khoom siv hluavtaws hluavtaws. Vim tias cov roj ntxhia yog cov sib xyaw ntawm ntau hom hydrocarbons, nws yog ib qho nyuaj rau tshem tawm cov khoom uas txo cov rwb thaiv tsev, thiab cov txheej txheem kev npaj yog complex, yooj yim rau hlawv, tsis tshua muaj kub tsis kam, thiab dielectric tsis tu ncua tsis siab, yog li cov roj ntxhia yog cov sib xyaw ntawm ntau hom hydrocarbons. hluavtaws insulating roj nrog kev ua tau zoo heev tau tshawb fawb thiab tsim. Tam sim no siv cov roj hluavtaws hluavtaws, silicone roj, ester roj, ether thiab sulfone hluavtaws roj, polybutene, thiab lwm yam. Cov roj zaub yog siv rau hauv cov roj castor, soybean roj, rapeseed roj, thiab lwm yam ntawm lawv, castor roj yog ib qho zoo heev impregnating tus neeg sawv cev. rau pulse capacitor
