Xaiv lub polymer insulator nrog siab tiv thaiv xob laim, zoo heev muaj kuab paug flashover tiv thaiv, thiab lub neej ntev yog qhov tseem ceeb rau kev nyab xeeb ntawm lub zog hluav taws xob thiab ua kom ntseeg tau cov khoom siv hluav taws xob.
Composite insulators yog tsim los ntawm epoxy iav fiber core pas nrig thiab silicone roj hmab ua thawj insulator. Lub epoxy iav fiber ntau pas nrig muaj lub zog txhua yam 1.6 txog 2. Peb-txheej silicone roj hmab insulator tiab muaj cov pa phem flashover zoo heev thiab tsis tawg, tawg, lossis plam glaze raws li feem ntau pom nrog ceramic insulators. Txij li thaum nruab nrab txheej ntawm cov hluav taws xob insulator tiab muaj ib txoj kab uas hla me dua li cov khaubncaws sab nraud povtseg sab sauv thiab qis, lub tsho sab sauv thiab sab qis tsis tsim cov yeeb yaj kiab txuas ntxiv, tiv thaiv kom tsis txhob muaj qhov cuam tshuam thermal tam sim no thiab yog li txo qhov tshwm sim ntawm insulator flashover.
Thaum tus pin-type composite insulator raug ntaus los ntawm xob laim, silicone roj hmab insulator tiab tsis tawg thiab pom pom pom qhov kub hnyiab, ua kom yooj yim rau cov neeg ua haujlwm saib xyuas. Kev ntsuas hluav taws xob zoo ntawm tus pin-hom sib xyaw insulators, suav nrog kev siv hluav taws xob qhuav, ntub flashover, thiab tiv taus qhov ntsuas hluav taws xob tom qab soaking cov insulators hauv dej rau ob peb teev, ua tau raws li cov qauv xav tau. Xav txog qhov kub thiab txias hauv zos, tsis muaj kev ntsuam xyuas thermal shock. Siv tus pin insulator yog ib qho kev ntsuas zoo los txo cov kab tsis raug.
01
Lub teeb nyhav
Composite insulators muaj qhov ntim me me thiab lub teeb yuag, kwv yees li 1/5 txog 1/7 ntawm cov porcelain insulators ntawm tib theem voltage, ua rau lawv yooj yim rau kev thauj thiab nruab.
02
High mechanical zog
Composite insulators muaj lub zog txhua yam, txhim khu kev qha, kev ua haujlwm ruaj khov, thiab muaj kev nyab xeeb loj rau kev ua haujlwm, ua kom muaj kev nyab xeeb ntawm cov kab hluav taws xob.
03
Zoo sealing zoo
Composite insulators tiv taus cov kua qaub thiab alkalis, thermal aging, thiab hluav taws xob yaig. Lawv muaj cov khoom zoo sealing, kom ntseeg tau tias cov rwb thaiv tsev sab hauv tsis ntub.
04
Zoo tiv thaiv brittleness
Composite insulators muaj qhov zoo los tiv thaiv brittleness thiab muaj zog poob siab, tiv thaiv kev sib tsoo tawg.
