Surge Arresters Cable thiab kev sib txuas ncaj qha hauv GIS system tsis raug rau xob laim. Vim hais tias GIS conductors nyob rau hauv ib tug grounded hlau enclosure, tib txoj kev rau xob laim impulse voltages nkag mus thiab ua kev puas tsuaj yog los ntawm kev sib txuas ntawm GIS mus rau seem ntawm cov hluav taws xob system. Yog li ntawd, kev tiv thaiv ntawm SF6- kev sib txuas rau-air bushing thiab ntawm transformers yog qhov tseem ceeb ntawm kev txhawj xeeb. Zinc oxide hom surge arrester caij yog zoo haum rau immersion nyob rau hauv ib qho chaw SF6. Cov no tau txais kev txhawb nqa los ntawm lub tog raj kheej insulating sab hauv GISenclosure.
Cua Insulated Surge Arresters vs Gas InsulatedAir-insulated surge arresters nyob rau hauv parallel nrog SF6-to-air bushings feem ntau muab kev tiv thaiv txaus ntawm GIS los ntawm xob laim impulse voltages ntawm tus nqi qis dua SF6-insulated ntes .
Nrog rau AIS - muaj qhov txo qis hauv kev tiv thaiv hluav taws xob rau kev hloov hluav taws xob piv rau xob laim impulse vim tias lub sijhawm ntev dua ntawm kev hloov hluav taws xob tso cai rau lub sijhawm tso tawm kom tag nrho txuas rau qhov ntev insulating nyob rau hauv huab cua.
Nrog rau GIS - qhov kev ncua deb ntawm cov rwb thaiv tsev luv luv tuaj yeem txuas rau lub sijhawm luv luv ntawm lub zog hluav taws xob; yog li lub sij hawm ntev dua ntawm kev hloov pauv hloov tsis tau txo qhov kev tawg ntawm qhov hluav taws xob. Rwb thaiv tsev kev sib koom tes kev tshawb fawb feem ntau qhia tias tsis tas yuav muaj cov neeg tua neeg coob coob hauv GIS; Txawm li cas los xij, ntau tus neeg siv qhia txog kev ntes cov neeg tawg rog ntawm kev hloov pauv thiab kev sib txuas cable raws li txoj hauv kev zoo tshaj plaws.
Surge Arresters Tester txais lub microcomputer rau sampling, tswj, thiab lwm yam advanced technology, thiab yuav ntsuas zinc oxide ntes nyob rau hauv lub hwj chim zaus voltage tag nrho tam sim no, thib peb harmonic, resistive tam sim no, resistive tam sim no ncov, capacitive tam sim no, active zog, thiab hais txog. Thiab tso saib voltage, tam sim no waveform, thiab luam tawm. Kev siv lub vijtsam loj LCD zaub, thiab cov ntawv qhia zaub mov ua haujlwm kom cov txiv neej-tshuab pauv kev ua haujlwm muaj zog dua. Nyob rau tib lub sij hawm muab cov kab hluav taws xob ntawm qhov chaw. Cov cuab yeej muaj cov yam ntxwv ntawm kev xaim yooj yim, ntsuas qhov tseeb, thiab muaj kev ntseeg tau zoo.
