Tlhaloso ea Sehlahisoa
Insulator ea poso ke taolo e khethehileng ea ho koala e ka bapalang karolo ea bohlokoa moleng oa phetisetso o holimo.Lilemong tsa pele, li-insulators tsa litšiea li ne li sebelisoa haholo bakeng sa lipalo tsa thelefono, tse ileng tsa ntlafatsoa butle-butle hore li fanyehe li-insulators tse ngata tse emisitsoeng qetellong ea tora ea terata e phahameng ea motlakase ho eketsa sebaka sa creepage.Hangata li entsoe ka gel ea silica kapa ceramic, 'me li bitsoa li-insulators.
Insulator meleng ea phetisetso e holimo e nang le karolo e 'meli ea motheo, e leng terata ea tšehetso le ho thibela mokokotlo oa morao-rao, mesebetsi ena e' meli e tlameha ho tiisetsoa, insulator ha ea lokela ho hlahisa phetoho ka lebaka la maemo a tikoloho le a motlakase a lebisang ho senyeha le ho hlōleha ha flashover, kapa insulator e tla lahleha. , e tla senya mokhoa oohle oa ts'ebeliso le bophelo ba ts'ebetso.
Tshebetso
1. Li-insulators tsa poso li lumellana le litokisetso tsa GB8287.1 "Technical Conditions for High Voltage Post Porcelain Insulators" le GB12744 "Pollution Resistant Outdoor Bar Post Porcelain Insulators".E boetse e lumellana le litlhoko tsa litekanyetso tsa machaba tsa IEC168, Liteko tsa Ceramic kapa Glass Post Insulators bakeng sa tšebeliso ea ka hare le ka ntle ho litsamaiso tse nang le Voltage ea lebitso ka holimo ho 1000 V, le khatiso ea IEC 815, Litaelo tsa khetho ea Li-Insulators tlas'a maemo a tšilafalo.
2, matla a mochini oa insulator a phahame, a hasana hanyane, ts'ebetso e bolokehileng le e tšepahalang.
3, ts'ebetso ea mochini oa insulator ea mocheso o tlase e ntle.
E le ho hlahloba lisebelisoa tsa mochine oa cryogenic oa sehlahisoa, mochine oa zSW1-110 / 4 o ile oa lekoa ka laboratoring ea cryogenic ea Institute of Water Resources, Songliao Water Conservancy Commission, ho etsisa phetoho ea mocheso oa ka ntle mariha.Ka mor'a lipotoloho tse 'maloa tsa mocheso, likristale tsa teko li ile tsa lekoa bakeng sa ho hlōleha ho kobeha ka mocheso o tlaase.Liphetho tsa liteko li bonts'a hore matla a ho hloleha ho kobeha ha li-insulators ho -40 ℃ ha a na phetoho e kholo ha e bapisoa le mocheso oa kamore.
