12in Aluminium Alloy Corona Ring Rau Composite Insulator

Txhawm rau txo qhov cuam tshuam ntawm corona, corona rings feem ntau yog ntsia rau ntawm ib lossis ob qho kawg ntawm lub insulator, txuas rau qhov kawg fittings. Thaum corona rings feem ntau pom tau tias tsim nyog rau qhov system voltages ntawm 230kV thiab saum toj no, muaj cov xwm txheej uas qis dua qhov system voltages yuav xav tau lawv siv rau kev tiv thaiv corona.

Lub nplhaib corona yog xav tau nyob rau ntawm kab kawg ntawm lub insulator, txoj cai ntawm qhov kawg haum thiab roj hmab interface, uas yog thaj tsam ntawm cov hluav taws xob siab tshaj plaws ntawm lub plhaub ntawm lub insulator. Raws li daim ntawv thov voltage nce, txoj kab uas hla ntawm lub nplhaib corona nce mus rau qib zoo ntawm cov hluav taws xob.

High voltages tuaj yeem ua rau lub suab tsis xav tau (RIV) thiab corona. Txhawm rau txo qhov cuam tshuam ntawm corona, corona rings yog siv rau ib lossis ob qho kawg ntawm cov insulator, txuas mus rau qhov kawg fittings. Feem ntau, rau qhov system voltages ntawm 230kV thiab saum toj no, lub nplhaib corona los yog ua ke ntawm cov nplhaib yog tsim nyog. Txawm li cas los xij, qee qhov kev siv yuav xav tau cov nplhaib ntawm qhov qis dua qhov system voltages.
