I-P-70 yePorcelain Post Insulator

I-P-70 yoMfanekiso wePorcelain wePorcelain oboniswayo

Inkcazelo emfutshane:

I-insulator yePost lulawulo olukhethekileyo lwe-insulator olunokuthi ludlale indima ebalulekileyo kumgca wokuhambisa ngaphezulu.Kwiminyaka yokuqala, ii-insulators zentsika zazisetyenziswa kakhulu kwiipali zefowuni, eziye zaphuhliswa ngokuthe ngcembe ukuxhoma izinto ezininzi zokuxhoma-ezifana ne-insulators ekupheleni kwe-high-voltage wire connection tower ukwandisa umgama we-creepage.Ngokuqhelekileyo zenziwe nge-silica gel okanye i-ceramic, kwaye zibizwa ngokuba yi-insulators.
Isigqubuthelo sentonga yamandla ombane aphezulu sisetyenziswa njenge-insulator kunye ne-conductor exhasayo kwi-high voltage transmission kunye nomgca wokusabalalisa.Imveliso sisakhiwo esingaqhawukiyo kwaye sineengenelo zamandla omatshini aphezulu, ukusebenza okuqinileyo kokugquma kunye nokumelana nongcoliseko okulungileyo.I-insulator ineenzuzo zokusebenza okukhuselekileyo nokuthembekileyo, ukugcinwa okulula, ubomi benkonzo ende kunye neendleko zomgca ophantsi.

I-insulator yePost lulawulo olukhethekileyo lwe-insulator olunokuthi ludlale indima ebalulekileyo kumgca wokuhambisa ngaphezulu.Kwiminyaka yokuqala, ii-insulators zentsika zazisetyenziswa kakhulu kwiipali zefowuni, eziye zaphuhliswa ngokuthe ngcembe ukuxhoma izinto ezininzi zokuxhoma-ezifana ne-insulators ekupheleni kwe-high-voltage wire connection tower ukwandisa umgama we-creepage.Ngokuqhelekileyo zenziwe nge-silica gel okanye i-ceramic, kwaye zibizwa ngokuba yi-insulators.
I-insulator kwimigca yokuhanjiswa kwe-overhead enendima ezimbini ezisisiseko, ezizezi zenkxaso yocingo kunye nokuthintela umva wangoku, le misebenzi mibini kufuneka iqinisekiswe, i-insulator akufanele ivelise utshintsho ngenxa yokusingqongileyo kunye neemeko zomthwalo wombane ezikhokelela ekuqhekekeni kunye nokungaphumeleli kwe-flashover, okanye i-insulator iya kulahleka. , iya kuwonakalisa umgca wokusetyenziswa kunye nobomi bokusebenza.

Ukusebenza

1. Izikhuseli zePosi zingqinelana nemigaqo ye-GB8287.1 “Iimeko zeTechnical Conditions for High Voltage Post Porcelain Insulators” kunye ne-GB12744 “Pollution Resistant Outdoor Bar Post Porcelain Insulators”.Ikwahambelana neemfuno zomgangatho wamazwe ngamazwe we-IEC168, iimvavanyo kwiCeramic okanye iglasi yePost Insulators yokusetyenziswa kwangaphakathi nangaphandle kwiinkqubo ezineVoltages ezibizwa ngokuba yi-1000 V, kunye ne-IEC yokupapashwa kwe-815, Izikhokelo zokukhethwa kwee-Insulators phantsi kweemeko zokungcola.

I-2, amandla omatshini we-insulator aphezulu, ukusabalalisa okuncinci, ukusebenza okukhuselekileyo kunye nokuthembekileyo.

I-3, i-insulator yobushushu obuphantsi bokusebenza komatshini kulungile.
Ukuze uvavanye iimpawu ze-cryogenic mechanical zemveliso, i-insulator ye-zSW1-110 / 4 yavavanywa kwi-laboratory ye-cryogenic ye-Institute of Water Resources, iKomishoni ye-Songliao Water Conservancy, ukulinganisa utshintsho lobushushu bangaphandle ebusika.Emva kwemijikelo emininzi yobushushu, iikristale zovavanyo zavavanywa ukusilela ukugoba kwiqondo lobushushu eliphantsi.Iziphumo zovavanyo zibonisa ukuba ukomelela kokugoba kwee-insulators kwi-40℃ ayinalo utshintsho olubalulekileyo xa kuthelekiswa nobushushu begumbi.

4. Ukuphazamiseka kwerediyo ephantsi.
Isigqubuthelo esinamandla ombane olinganisiweyo wama-550kV sinokuvelisa uphazamiseko lukanomathotholo olungekho ngaphezulu kwe-500μV kumaxesha ayi-1.1 owona mbane uphezulu wesigaba sokusebenza, akukho corona ibonakalayo ngobusuku obucacileyo, namandla ombane e-corona abonakalayo ukuya kuthi ga kwi-450kV.
