ZF16-252(L)/Y4000-50 Gas Insulated Metal-Enclosed Switchgear (hereinafter referred to as GIS) is applicable for the electrical system with features of three phases AC,50Hz, and rated voltage of 252kV.
ZF16 252kV Gas Insulated Switchgear
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.
