P-70 Porcelain Post Insulator

Kufotokozera Kwachidule:

Post insulator ndi chida chapadera chowongolera chomwe chimatha kugwira ntchito yofunika kwambiri pamakina opatsira pamutu.M'zaka zoyambilira, ma insulators a mzati amagwiritsidwa ntchito kwambiri pamitengo ya foni, yomwe idapangidwa pang'onopang'ono kuti ipachike ma insulators ambiri oyimitsidwa kumapeto kwa nsanja yolumikizira waya yamagetsi kuti awonjezere mtunda wa creepage.Nthawi zambiri amapangidwa ndi silika gel kapena ceramic, ndipo amatchedwa insulators.
High voltage line rod insulator imagwiritsidwa ntchito ngati kutchinjiriza ndi kondakitala wothandizira pamagetsi apamwamba komanso mzere wogawa.Chogulitsacho ndi chosawonongeka ndipo chili ndi ubwino wa mphamvu zamakina apamwamba, ntchito zolimba za kutchinjiriza komanso kukana kuwononga chilengedwe.Insulator ili ndi ubwino wa ntchito yotetezeka komanso yodalirika, kukonza kosavuta, moyo wautali wautumiki komanso mtengo wotsika mtengo.

Post insulator ndi chida chapadera chowongolera chomwe chimatha kugwira ntchito yofunika kwambiri pamakina opatsira pamutu.M'zaka zoyambilira, ma insulators a mzati amagwiritsidwa ntchito kwambiri pamitengo ya foni, yomwe idapangidwa pang'onopang'ono kuti ipachike ma insulators ambiri oyimitsidwa kumapeto kwa nsanja yolumikizira waya yamagetsi kuti awonjezere mtunda wa creepage.Nthawi zambiri amapangidwa ndi silika gel kapena ceramic, ndipo amatchedwa insulators.
Insulator mu mizere yopatsirana yam'mwamba yokhala ndi ntchito ziwiri zofunika, zomwe ndi waya wothandizira ndikuletsa kumbuyo kwapano, ntchito ziwirizi ziyenera kutsimikiziridwa, zotchingira siziyenera kubweretsa kusintha chifukwa cha chilengedwe ndi zinthu zamagetsi zomwe zimabweretsa kuwonongeka ndi kulephera kwa flashover, kapena insulator idzatayika. , idzawononga njira yonse yogwiritsira ntchito ndi moyo wogwira ntchito.

Kachitidwe

1. Post insulators ikugwirizana ndi zomwe GB8287.1 "Technical Conditions for High Voltage Post Porcelain Insulators" ndi GB12744 "Pollution Resistant Outdoor Bar Post Porcelain Insulators".Imagwirizananso ndi zofunikira za muyezo wapadziko lonse wa IEC168, Mayeso a Ceramic kapena magalasi oteteza magalasi kuti agwiritsidwe ntchito mkati ndi kunja m'makina omwe ali ndi ma Voltage apamwamba kuposa 1000 V, ndi IEC yofalitsa 815, Malangizo pakusankha Ma Insulators pansi pazikhalidwe zoipitsidwa.

2, insulator makina mphamvu ndi mkulu, ang'onoang'ono kubalalitsidwa, otetezeka ndi odalirika ntchito.

3, insulator otsika kutentha makina ntchito bwino.
Pofuna kuyesa ma cryogenic mechanical properties, zSW1-110/4 insulator inayesedwa mu labotale ya cryogenic ya Institute of Water Resources, Songliao Water Conservancy Commission, kuti ayese kusintha kwa kutentha kwakunja m'nyengo yozizira.Pambuyo pazigawo zingapo za kutentha, makhiristo oyesera adayesedwa kuti alephera kupindika pa kutentha kochepa.Zotsatira zoyeserera zikuwonetsa kuti kulephera kopindika kwa ma insulators pa -40 ℃ kulibe kusintha kwakukulu poyerekeza ndi kutentha kwachipinda.

4. Kusokoneza wailesi yapansi.
Insulator yokhala ndi voteji ya 550kV imatha kusokoneza mawayilesi osapitilira 500μV nthawi 1.1 kuchuluka kwamagetsi opangira opaleshoni, palibe korona wowoneka bwino usiku, komanso voteji yowoneka bwino ya corona mpaka 450kV.
