Polymer Hluav Taws Xob Insulators
Composite ncej insulators
Hauv kev sib piv rau cov pas nrig ntev ntev, cov khoom sib txuas tom qab insulators yog feem ntau yog cov khoom thauj uas ua rau perpendicular mus rau longitudinal axis ntawm lub insulator thiab yog li tsim khoov kev ntxhov siab nyob rau hauv cross-section ntawm lub insulator. Raws li qhov tshwm sim ntawm qhov kev khoov no, cov khoom siv txuas ntxiv siv FRP rods ntawm txoj kab uas hla ntau dua piv rau cov pas nrig ntev. Cov ntawv thov kev sib txuas ntawm cov khoom siv hluav taws xob muaj xws li cov khoom siv hluav taws xob faib hluav taws xob, cov kab ntsug thiab kab rov tav, busbar txhawb insulators thiab railway catenary insulators.
Composite ntev pas nrig insulators
Composite ntev pas nrig insulators feem ntau yog siv nyob rau hauv ncua kev kawm ntawv cov hlua nyob rau hauv ncaj-line txhawb nqa thiab raws li nro cov hlua nyob rau hauv thauj tog rau nkoj yees thiab tuag-kawg yees. Lawv kuj tau siv nyob rau hauv jumpers lossis portals ntawm sab nraum zoov substations. Qee zaum, cov pas nrig ntev sib xyaw yog siv rau hauv cov txiv neej ntawm cov ncej ntoo, thiab tsis tshua muaj nyob rau hauv cov txiv neej ntawm cov yees.
Interphase spacers
Kab compaction feem ntau yog raws li lub hauv paus ntsiab lus ntawm minimizing interphase spacing. Raws li qhov tshwm sim ntawm qhov no, thiab tseem vim tias qhov sib txuas sib txuas me me me dua li qhov tau ntsib nyob rau hauv rooj plaub ntawm cov kab hluav taws xob ib txwm siv hluav taws xob, muaj kev pheej hmoo ntau dua ntawm interphase flashover nrog lub compact tsim thaum ob lub conductors txav ze rau ib leeg, piv txwv li. raws li cua, dej khov los yog luv luv; qhov no yuav ua rau muaj kev cuam tshuam hauv kev pabcuam. Interphase spacers (IPS) yog siv los zam qhov no.
Qhov zoo
| Yam khoom | Composite Insulators |
| Hydrophobicity | Cov cuab yeej hydrophobic ntawm silicone roj hmab muaj cov rwb thaiv tsev zoo heev thiab tiv thaiv kom ntub dej, ua cov hlaws dej tsis tas yuav tsum tau ntxuav los yog grease, txawm nyob rau hauv huab cua ntub los yog muaj kuab paug. |
| Contamination & Pollution Performance | Zoo heev |
| Kev tu | Nws tuaj yeem txo cov nqi kev ua haujlwm ntawm txoj kab, txo hluav taws xob poob, thiab kev siv zog ntawm kev siv. |
| Qhov loj thiab qhov hnyav | Qhov loj me me thiab lub teeb yuag (kwv yees li 1/7 txog 1/10 qhov loj ntawm qhov sib npaug porcelain insulator hlua), lub kaus tiab nthuav tawm cov elasticity zoo heev, tiv taus kev tawg, ua kom yooj yim kev thauj mus los thiab kev teeb tsa, thiab raug nqi zoo. |
| Mechanical Load | Lub fiberglass tub ntxhais pas nrig muaj lub zog tensile siab, uas yog 5 mus rau 10 npaug ntawm cov ntaub ntawv ceramic. Vim yog qhov me me ntawm tus pas nrig, cov khoom muaj qhov me me thiab lub teeb yuag, siab khoov lub zog, thiab yooj yim los tsim cov khoom loj tonnage ntau tshaj 300kN. |
| Lub sij hawm xa tuaj | Cov txheej txheem tsim khoom yog yooj yim, thiab lub sijhawm xa khoom luv luv. |
