P-70 Porcelain Post Insulator
Product Definition
Post insulator ndeye yakakosha insulation control iyo inogona kuita basa rakakosha mumusoro wekufambisa tambo.Mumakore ekutanga, mbiru insulators yainyanya kushandiswa pamatanda efoni, ayo akagadzirwa zvishoma nezvishoma kuti aturike akawanda ekumisa-senge insulators pamagumo eiyo high-voltage waya yekubatanidza tower kuti iwedzere kureba kwecreepage.Iyo inowanzogadzirwa nesilika gel kana ceramic, uye inonzi insulators.
Insulator mumitsetse yekufambisa yepamusoro ine maviri akakosha basa, kureva waya yekutsigira uye kudzivirira iyo yazvino kumashure, mabasa maviri aya anofanirwa kuvimbiswa, insulator haifanirwe kuburitsa shanduko nekuda kwemamiriro ekunze uye magetsi ekutakura zvinhu zvinokonzeresa kuparara uye kutadza kweflashover, kana insulator icharasika. , ichakuvadza mutsara wose wekushandiswa uye hupenyu hwekushanda.
Performance
1. Post insulators inoenderana nezvinodiwa zveGB8287.1 "Technical Conditions for High Voltage Post Porcelain Insulators" uye GB12744 "Pollution Resistant Outdoor Bar Post Porcelain Insulators".Inopindiranawo nezvinodiwa zveInternational standard IEC168, Miedzo paCeramic kana girazi Post Insulators yekushandiswa kwemukati nekunze mumasisitimu ane zita remagetsi pamusoro pe1000 V, uye IEC kudhindwa 815, Nhungamiro yekusarudzwa kweInsulators pasi pemamiriro ekusvibiswa.
2, insulator mechanical simba yakakwira, kupararira kudiki, kwakachengeteka uye kwakavimbika kushanda.
3, insulator yakaderera tembiricha mechanical performance yakanaka.
Kuti uedze iyo cryogenic mechanical properties yechigadzirwa, zSW1-110/4 insulator yakaedzwa murabhoritari ye cryogenic yeInstitute of Water Resources, Songliao Water Conservancy Commission, kutevedzera kuchinja kwekushisa kwekunze munguva yechando.Mushure mekutenderera kwakati wandei tembiricha, makristasi ebvunzo akaedzwa kutadza kukotama pane tembiricha yakaderera.Mhedzisiro yemuyedzo inoratidza kuti kukotama kutadza simba kwema insulators pa -40 ℃ haina shanduko yakakosha kana ichienzaniswa neiyo pakamuri tembiricha.
4. Kupindira kweredhiyo kwakaderera.
Insulator ine rated voltage ye550kV inogona kuburitsa redhiyo kuvhiringa kusingapfuuri 500μV pa1.1 times the maximum operating phase voltage, hapana corona inooneka pahusiku hwakajeka, uye inoonekwa corona voltage inosvika 450kV.
