The 252kV gas insulated switchgear meets the relative requirements of the national standard-GB7674-2008 and international standard IEC60517. All the components inside the GIS switchgear conform to the corresponding national standard. The standard GIS switchgear operation mechanism is fitted with a spring or hydraulic system. Type tests have been passed in KEMA, with a rated frequency of 50Hz and 60Hz.
The ZF16 252kV sf6 gas insulated switchgear Structure and Features:
▪Circuit breaker adopts compressed gas + thermal expansion self arc-extinguishing Principle.
▪Strong ability of breaking, up to 70kA, and 53% DC component, short-time arc, full breaking time of 2-cycle and long electrical endurance of 20 times full breaking without maintenance.
▪ABB hydraulic spring operating mechanism with compact structure, high reliability, little maintenance and mechanical endurance up to 10000 times.
▪Disconnector, earthing switch, and high-speed earthing switch are operated by motor or motor & spring mechanism,realizing three-phase mechanical interlock operation.
▪Standard modular structure and high-applicability for projects.
▪Mature standard modular promises flexibility for project design and supplies double bus bar,one and a half connection and connection according to clients' requirements.
