Bayani na sayen daga mai wuyaci
Na ɗan ɗaya na ƙasa mai sarrafa ɗan ɗaya 550kV ita ce ƙasashen yawa a cikin gas insulated metal enclosed switchgear (GIS). Wannan shine bayanai game da shi:
Kudancin kudin
Kudin gaba: Daga "Technical Conditions for Insulation Rod for 550kV and Above AC Gas Insulated Metal Enclosed Switchgear", ɗan ɗaya na ƙasa mai sarrafa 550kV ana iya zama ne daga ƙasar da kuma abubuwa masu gaba. Ƙasar tana nuna ɗan ɗaya mai sarrafa a kan ruwan epoxy resin mai sarrafa na fiber, kuma abubuwa masu gaba suna nufin azumi a matsayin kamar kaya don inganta su da sauran baka.
Hanyar inganta: Ɗan ɗaya na ƙasa mai sarrafa 550kV ana yi hanyar inganta mai suna ƙungiyoyi ta hanyar meshi mai ƙungiyoyi a kan ƙaramin kaya da ƙungiyoyi masu suna. Wannan kudin ya taimaka wajen zama ƙasar ɗan ɗaya mai sarrafa da kuma inganta da kyau a kan abubuwa masu gaba da ƙasar.
Zabinta abubuwa
Abubuwan ɗan ɗaya suna nufin glass fiber a kan ƙasar. Glass fiber tana da ƙasar da modulus mai yawa, wanda yake iya bayyana ƙarakara mai kyau ga ɗan ɗaya. Amma, ruwan epoxy resin tana da ƙwarewa mai kyau da kuma ƙarfin haɗa. A nan, wannan abubuwan glass fiber reinforced epoxy resin composite material tana iya tabbatar da ƙwarewa da ƙarakara ga ɗan ɗaya a ƙasashe 550kV.
Talabukan ƙwarewa
Ƙarakara: tensile strength ≥ 400MPa, compressive strength ≥ 400MPa, parallel layer shear strength ≥ 40MPa, interlayer bonding strength ≥ 4000N, don tabbatar da ƙarfin ya zama da shi a ƙarshen tsirrai, kwallon rike, da kuma tsirrai a lokacin da ake amfani da shi.
Ƙwarewa: parallel layer electrical strength ≥ 8kV/mm, vertical layer electrical strength ≥ 18kV/mm, volume resistivity ≥ 1.0 × 10 ¹⁵Ω· cm, dielectric loss factor ≤ 0.7%, relative dielectric constant of 3-5, ƙwarewa mai kyau, za a iya inganta harshe mai kyau.
Sauran ƙwarewa: Water absorption rate ≤ 0.1%, glass transition temperature ≥ 115 ℃, ƙwarewa mai kyau a kan yankin da kuma ƙarfi, za a iya amfani da shi a lokacin da yawan tsakanin yankunan da ƙarfin.
Tsarin ƙofa
Hanyar vacuum impregnation: A yi hanyar vacuum pressure impregnation (VPI), ana sarrafa glass fiber cloth da ruwan epoxy resin system a kan ƙarfi, sannan ana ƙofa shi. Wannan hanyar tana taimaka wajen ƙare ƙwadon ruwa a kan ƙasar da kuma zama ƙwarewa mai kyau.
Tsarin ƙoyarwa: Ana ƙoyarwa da karɓe ƙasar mai sarrafa don ƙofofin ɗan ɗaya mai sarrafa da take da ƙasa. Sannan, ana inganta abubuwan masu gaba da ƙasar mai sarrafa ta hanyar sadarwa ko hanyar mekaniki
