High Voltage 70kn Disc Suspension Yakaomeswa Girazi Insulator U70BL

Tsanangudzo Pfupi

Chimiro chegirazi insulator chakafanana neicho cheporcelain insulator, kunze kwekuti iyo insulator igirazi.Iyo huru yezvigadzirwa zvegirazi insulator ichasanganisira jecha requartz, feldspar, limestone, dolomite, soda ash, potassium carbonate, nezvimwewo girazi rinopisa rinoumbwa nemaitiro ekuita kwegirazi insulator ine homogeneous silicate, iyo yemukati microstructure kufanana kuri nani pane iyo ye electric porcelain, uye ine nani dielectric simba.Panguva imwecheteyo, pamusoro pegirazi yakanyoroveswa ine prestress uye yakanakisa thermal kugadzikana

3 Kuiswa

3.1 Kutarisa Chitarisiko
Iyo insulators ichaongororwa imwe neimwe zvichienderana nechitsauko 28 cheGB/ T1001.1-2003 uye iyi chiyero isati yaiswa, uye kushandiswa kwemainsulators asingaite zvinodiwa pamusoro apa kucharambidzwa.

3.2 Insulator kuramba kuyerwa
Insulation resistance ye porcelain insulators inoyerwa imwe neimwe isati yaiswa.Insulators isingaite zvinodiwa zveDLT626 haifanirwe kushandiswa.

3.3 Chengetedzo
Panguva yekuisa, insulators inofanira kubatwa nekuchenjerera, kwete kukandwa, uye kudzivisa kudhumhana uye kupesana nezvinhu zvinopinza.

4 Kushanda uye Kuchengetedza
4.1 gwaro
Iyo inoshanda unit ichagadzira mafaira e insulator zvinoenderana neDL/T 626.

4.2 kuchengetedza
Panguva yekuongorora uye kuongororwa kwezvidziviriro, kana zvikaonekwa kuti pini yekukiya haipo kana kuti insulator ine zero kukosha, kushanda kwehupenyu kana kutadza kugadzirisa magetsi kuchagamuchirwa, uye insulators ichaongororwa munguva maererano nezvinodiwa zvinotevera.
Kana imwe yeiyi inotevera mamiriro ikaitika, iyo insulator inogona kutsanangurwa kuti haina basa.A) Kutsemuka uye yero ngura makwapa anoonekwa pane yesimbi cap (acid reflux);B) Kupeta uye kuputika kwemakumbo esimbi;C) Kupisa kwakanyanya kwearc yesimbi cap uye simbi tsoka;
D) chivharo chesimbi, kuvhara uye tsoka yesimbi haisi pane imwe axis: e) porcelain kuputika kunoitika;
F) Insulation zvikamu zvinopiswa zvakanyanya nekubuda kwechidimbu uye kubuda kwechidimbu kunoitika;G) Mitswe kana skew inoonekwa musimende patsoka yesimbi;
H) Kuora kwemakumbo esimbi kunoitika sezvinotsanangurwa muDLT626-2005.
