13KN PW-33-Y High Voltage Pin Type Porcelain Insulator

Tanthauzo la Zamalonda

Pini insulator ndi chigawo chomwe chimagwiritsidwa ntchito kuthandizira kapena kuyimitsa waya ndikupanga zotsekera zamagetsi pakati pa nsanja ndi waya [1].Pini wamba wa ceramic insulator zadothi zadothi ndi zitsulo zotayidwa zimamatidwa pamodzi ndi zomatira simenti, ndipo pamwamba pazigawo zadothi zimakutidwa ndi wosanjikiza wa glaze kuti apititse patsogolo magwiridwe antchito a insulator.
Ma insulators azikhala ndi mphamvu zokwanira zotchingira komanso mphamvu zamakina.Panthawi yogwira ntchito, ma insulators samangokhalira kupirira mphamvu yamagetsi ndi mphamvu yowonjezera, komanso amakhala ndi kukana kokwanira kukokoloka kwa zonyansa za mankhwala, ndipo amatha kutengera kusintha kwa kutentha ndi malo ozungulira.

Zofunikira za ma pin insulators zimaphatikizapo magetsi, makina ndi matenthedwe.Kuphatikiza apo, pali kukana kwachilengedwe komanso kukana kukalamba ndi zinthu zina.

(1) Kugwira kwamagetsi: Kutulutsa kowononga komwe kumakhala kotchingira kumatchedwa flashover, ndipo mawonekedwe a flashover ndiye mphamvu yayikulu yamagetsi yama insulators.Pamitundu yosiyanasiyana yamagetsi, ma insulators ali ndi zofunikira zosiyanasiyana zololera ma voltage, kuphatikiza kupirira kwamagetsi kowuma komanso kunyowa kwamagetsi, kulekerera kwamagetsi amphezi, kulekerera kwamphamvu kwamagetsi, kulekerera kwamagetsi, komanso kulekerera kwamagetsi.Kuti mupewe kuwonongeka panthawi yogwira ntchito, mphamvu yowonongeka ya insulator ndi yapamwamba kuposa magetsi a flashover.Mu mayeso a fakitale, chotchingira chamtundu wa porcelain nthawi zambiri chimadutsa pamayeso a spark, ndiye kuti, voteji yayikulu imachulukitsidwa kuti ziwopsezo zizichitika pafupipafupi pamtunda, ndikusunga kwakanthawi kuti awone ngati zasweka.Ma insulators ena amafunika kuyezetsa corona, kuyezetsa kusokonezedwa ndi wailesi, kuyezetsa kutulutsa pang'ono komanso kutayika kwa dielectric.Mphamvu yamagetsi ya ma insulators m'malo okwera imachepa chifukwa cha kuchepa kwa kachulukidwe ka mpweya, motero mphamvu yawo yolimbana nayo iyenera kuonjezedwa ikasinthidwa kukhala mlengalenga.The flashover voteji wa zoipitsa insulators pamene amakhudzidwa ndi chinyezi ndi otsika kwambiri kuposa awo youma ndi chonyowa flashover voteji.Chifukwa chake, kutchinjiriza kuyenera kulimbikitsidwa kapena zotchingira zolimbana ndi kuipitsidwa ziyenera kugwiritsidwa ntchito m'malo oipitsidwa, ndipo mtunda wa creepage (chiŵerengero cha mtunda wa creepage mpaka ma voliyumu ovotera) uyenera kukhala wapamwamba kuposa wa zotsekera wamba.Poyerekeza ndi AC insulators, DC insulators ndi osauka kugawa magetsi m'munda, adsorption wa particles kuipitsa ndi electrolysis, otsika flashover voteji, ndipo kawirikawiri amafuna structural kapangidwe ndi lalikulu creepage mtunda.
