Baton isolasyonu 252kV GIS kesici için

Na ƙarfin daɗi na 252kV GIS circuit breaker yana cikin abubuwa mai muhimmanci a cikin gas insulated metal enclosed switchgear (GIS) daga baya. Abubuwan da kuma tarihin samun daɗi a kasar suna haka:
1、Muhimmancin abubuwan da ke sa
Kyakkyawan daɗi na tsakiyar
Yana buƙatar da shi da kyau don ci 252kV power frequency voltage (1210kV/1min) da lightning impulse voltage (± 2400kV/15 times), ta haka dielectric strength of ≥ 30kV/mm
Tsarin daɗi na rarraba yana buƙatar da shi da kyau don ci ƙarshen 15kV/mm don ya haɓaka surface discharge
Kyakkyawan mekaniki
Tensile strength yana buƙatar da shi da 390kN, mechanical life should be ≥ 10000 times, and dynamic response frequency should be 0-600Hz
Maximum strain under the impact of opening and closing is concentrated at the bonding point on the contact side, which needs to be verified through 100 full capacity short-circuit current tests
2、Abubuwa da Kudin Kirkiro
Abubuwan da suka fi sani
Fiberglass epoxy composite material: high mechanical strength, but fiber arrangement needs to be optimized to reduce the risk of crack propagation
Aramid/polyester fiber epoxy composite material: lightweight and fatigue resistant, suitable for high voltage levels
Kudin kirkiro mai sauƙi
Adopting non threaded bonding technology to avoid stress concentration caused by threaded structures
3、Samun Daɗi da Amfani da shi a Ingantattun
Amfani da shi masu ma'ana
252kV GIS an amfani da shi a fannin tsarin karamin ingantattun, 126kV GIS ita ce da yake daidai a fannin tsarin karamin energy generation projects
4、Kyakkyawan da Dangosan
Compliant with GB/T 11022-2020 and IEC 60694 standards, the dynamic characteristic testing method has been included in the technical specifications

Note: Customization with drawings is available
