1. Dab tsi yog Composite Insulator?
A composite insulator(los yog polymeric insulator) yog cov cuab yeej hluav taws xob niaj hnub siv hluav taws xob siv hauv high -voltage transmissions, substations, and railways. Nws muab cov fiberglass reinforced yas (FRP) core nrog silicone roj hmab vaj tse, muab cov khoom siv zog zoo, tsim qauv, thiab muaj kuab paug tiv thaiv piv rau cov plooj (porcelain / iav insulators).
2. Composite Insulator Structure
Composite insulators muaj xws lifiberglass tub ntxhais qws, silicone roj hmab vaj tse, nplaum txheej, kawg fittings, thiab muab qhab nia rings.Txhua yam khoom ua lub luag haujlwm tseem ceeb hauv kev ua kom lub zog ntawm lub zog, hluav taws xob rwb thaiv tsev, thiab kev cia siab ntev ntev -.
2.1 Core Rod
Cov pas nrig tseem ceeb yog qhov tseem ceeb ntawm cov khoom thauj -cov kabmob thiab ib feem tseem ceeb ntawm cov rwb thaiv tsev sab hauv. Nws yuav tsum ua kom muaj zog txhua yam, zoo heev rwb thaiv tsev zog, thiab ntev - lub sij hawm stability.
· Fiberglass reinforcement:Cov tub ntxhais pas nrig yog ntxiv dag zog nrog siab - lub zog iav fibers, yaj ntawm qhov kub thiab txias rau hauv cov cylindrical cov hlua (inch tsawg dua lossis sib npaug li 10μm) nrog lub zog tensile ntawm kwv yees li 1500 MPa.
· Epoxy resin matrix:Cov fibers tau sib koom ua ke siv cov epoxy resin matrix kho nrog silicone -raws li tus neeg sawv cev sib txuas, tsim cov epoxy fiberglass reinforced pas nrig (FRP pas nrig) uas xa cov khoom siv tshuab.
2.2 Silicone Rubber Housing & Sheds
Lub tsev silicone roj hmab ua haujlwm raws li cov rwb thaiv tsev sab nraud, muab kev tiv thaiv rau ntub thiab muaj kuab paug flashover thaum tiv thaiv cov tub ntxhais qws los ntawm ib puag ncig degradation.
· Cov khoom muaj pes tsawg leeg:Lub tsev yog ua los ntawm high-kub vulcanized (HTV) silicone roj hmab, ntxiv dag zog rau cov neeg ua haujlwm sib txuas, nplaim hluav taws, cov khoom siv ntxiv, thiab cov tshuaj tiv thaiv kev laus.
2.3 Xaus Fitting Connection
Cov khoom siv hluav taws xob los ntawm cov neeg siv hluav taws xob raug xa mus rau cov tub ntxhais pas nrig los ntawm qhov kawg fittings (xws li, pob- thiab - qhov sib txuas), uas yog qhov kev ntxhov siab tshaj plaws - cov cheeb tsam.
· Kev cuam tshuam ntawm cov qauv: Cov qauv kev sib txuas sib txawv ua rau muaj kev sib txawv ntawm kev ntxhov siab, cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov khoom siv hluav taws xob.
· Qhov tseem ceeb tshaj plaws: Qhov zoo ntawm qhov kawg haum kev sib txuas txiav txim siab siv tag nrho cov tub ntxhais pas nrig lub zog thiab tag nrho cov neeg kho tshuab kev ntseeg tau.
2.4 Adhesive Bonding Txheej
Cov nplaum nplaum txuas cov silicone roj hmab vaj tsev rau cov tub ntxhais qws, ua kom muaj kev ncaj ncees thiab ua rau muaj kev cuam tshuam sab hauv.
· Cov txheej txheem thaum ntxov:Siv chav -kub- kho cov nplaum nrog segmented shed bonding.
· Kev daws teeb meem niaj hnub:Integrated txhaj- molded vaj tse nrog siab -kub- kho kev sib txuas txhim kho adhesion, txo qhov cuam tshuam, thiab ua kom tsis muaj dej tsis zoo rau kev ua haujlwm zoo rwb thaiv tsev.
2.5 Xaus Sealing Txheej
Qhov kawg sealing txheej bonds lub vaj tse, core pas nrig, thiab kawg fittings rau hauv ib chav tsev, kom ntseeg tau tias airtightness.
· Cov yam ntxwv tseem ceeb ntawm kev ua haujlwm:Sealing zoo cuam tshuam ncaj qha rau hluav taws xob thiab cov khoom siv kho tshuab.
2.6 Qib Nplhaib
Qib rings yog qhov tseem ceeb rau:
· Electric teb tswj:Uniform voltage tis raws lub insulator axis.
· Kev tiv thaiv Corona:Tiv thaiv kev tso tawm ib nrab.
· Insulator tiv thaiv:Txhim kho lub sij hawm ntev - durability.
