Composite Substation Kab Post Insulator
Composite ncej insulators
Composite post insulators, tsis zoo li cov pas nrig ntev, feem ntau yog thauj khoom perpendicular mus rau longitudinal axis ntawm insulator, tsim flexural stresses hla hla ntu ntawm lub insulator. Raws li qhov tshwm sim ntawm qhov kev thauj khoom flexural no, cov khoom siv hluav taws xob sib txuas siv FRP rods uas muaj qhov loj ntawm txoj kab uas hla ntau dua li cov pas nrig ntev. Cov ntawv thov rau cov khoom siv hluav taws xob muaj xws li cov khoom siv 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 yog tsuas yog siv nyob rau hauv lub ncua kev kawm ntawv cov hlua ntawm lub linear txhawb thiab nyob rau hauv lub nro cov hlua ntawm lub thauj tog rau nkoj yees thiab cov tuag-kawg yees. Lawv kuj tau siv nyob rau hauv jumpers lossis portals ntawm sab nraum zoov substations. Nyob rau hauv cov txiv neej ntawm cov ntoo pylons thiab, tsawg zaus, nyob rau hauv cov txiv neej ntawm steel yees, composite ntev-rod insulators yog tej zaum siv.
Interphase spacers
Kab compaction feem ntau yog raws li lub hauv paus ntsiab lus ntawm minimizing interphase spacing. Raws li qhov tshwm sim, thiab vim tias qhov kev ncua deb ntawm cov theem me me dua li ntawm cov kab hluav taws xob ib txwm muaj, kev tsim qauv tsim muaj kev pheej hmoo ntau dua ntawm kev cuam tshuam ntawm lub sijhawm flashover thaum ob lub conductors txav ze rau ib leeg, xws li cua, dej khov tsim. -up lossis luv, thiab yog li cuam tshuam cov khoom siv. 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, tsim cov hlaws dej tsis tas yuav tsum tau ntxuav lossis grease, txawm tias nyob hauv huab cua ntub lossis 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 | Cov iav fiber ntau tus 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 me me, lub teeb hauv qhov hnyav, muaj zog flexural siab thiab tuaj yeem tsim tau yooj yim hauv 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. |
