P-70 Porcelain Post Insulator
Khoom txhais
Post insulator yog ib qho kev tiv thaiv tshwj xeeb uas tuaj yeem ua lub luag haujlwm tseem ceeb hauv cov kab hluav taws xob hluav taws xob.Nyob rau hauv thaum ntxov xyoo, pillar insulators feem ntau yog siv rau cov xov tooj ncej, uas tau maj mam tsim los dai ib tug ntau ntawm ncua kev kawm ntawv-zoo li insulators nyob rau hauv lub kawg ntawm high-voltage hlau txuas ntauwd kom lub creepage nrug.Lawv feem ntau yog ua los ntawm silica gel lossis ceramic, thiab hu ua insulators.
Insulator nyob rau hauv cov khoom siv hluav taws xob sib txuas nrog ob lub luag haujlwm tseem ceeb, uas yog kev txhawb nqa xaim thiab tiv thaiv rov qab tam sim no, ob txoj haujlwm no yuav tsum tau lees paub, insulator yuav tsum tsis txhob tsim kev hloov pauv vim ib puag ncig thiab hluav taws xob thauj khoom ua rau tawg thiab flashover tsis ua haujlwm, lossis insulator yuav ploj. , yuav ua rau tag nrho cov kab ntawm kev siv thiab kev khiav hauj lwm lub neej.
Kev ua tau zoo
1. Post insulators yog raws li cov kev cai ntawm GB8287.1 "Technical Conditions for High Voltage Post Porcelain Insulators" thiab GB12744 "Pollution Resistant Outdoor Bar Post Porcelain Insulators".Nws kuj ua tau raws li qhov yuav tsum tau ua ntawm tus txheej txheem thoob ntiaj teb IEC168, Kev Ntsuas ntawm Ceramic lossis iav Post Insulators rau kev siv sab hauv thiab sab nraum zoov hauv cov tshuab uas muaj qhov ntsuas hluav taws xob siab tshaj 1000 V, thiab IEC luam tawm 815, Cov Lus Qhia rau kev xaiv ntawm Insulators nyob rau hauv cov pa phem.
2, insulator mechanical zog yog siab, me me dispersion, kev nyab xeeb thiab txhim khu kev qha ua haujlwm.
3, insulator qis kub txhua yam kev ua tau zoo.
Txhawm rau kuaj cov khoom siv hluav taws xob cryogenic ntawm cov khoom, lub zSW1-110/4 insulator tau sim nyob rau hauv lub cryogenic laboratory ntawm lub koom haum ntawm dej Resources, Songliao Dej Conservancy Commission, simulate qhov kev hloov ntawm sab nraum zoov kub nyob rau hauv lub caij ntuj no.Tom qab ob peb lub voj voog kub, cov khoom siv lead ua tau raug sim rau kev khoov tsis ua haujlwm ntawm qhov kub qis.Cov txiaj ntsig kev sim qhia tau hais tias qhov khoov tsis ua haujlwm ntawm cov insulators ntawm -40 ℃ tsis muaj qhov hloov pauv loj piv nrog rau qhov kub ntawm chav tsev.
4. Tsawg xov tooj cua cuam tshuam.
Ib qho hluav taws xob uas muaj qhov ntsuas hluav taws xob ntawm 550kV tuaj yeem tsim hluav taws xob cuam tshuam tsis ntau dua 500μV ntawm 1.1 npaug ntawm qhov siab tshaj plaws kev khiav hauj lwm theem voltage, tsis pom corona nyob rau hmo ntuj, thiab pom corona voltage mus txog 450kV.
