**Brand: ROCKWILL** >220kV transmission substations, large solar/wind farm booster stations, urban central substations, heavy industrial power supply projects.
With the development of the power industry, the miniaturization of power equipment is the trend of future development and also the urgent need of current power users. Miniaturized electrical equipment can not only save and and civil engineering costs, etc., but also reduce the use of greenhouse gas SF6, meeting the requirements of the environmental protection situation. Combining years of high-voltage electrical design experience and absorbing the world's most advanced technical design concepts, our company has developed the latest generation of gasinsulated metal composite combined electrical appliance (HGIS). This combined electrical appliance has a compact structure and is particularly suitable for urban and mountainous substations. It is also the best choice for the renovation of old substations. In addition, this product is also very suitable for 40.5kV digital substations and can be used as digital electrical equipment.
RHP-245 is ROCKWILL segregated-tank hybrid gas insulated switchgear (HGIS) rated at 245kV, complying with IEC 62271-203, IEC 62271-100, IEC 62271-102, GB/T7674 and KEMA type tested. It adopts self-blast SF6 circuit breaker with bistable spring or spring-hydraulic operating mechanism. Available rated current:2000A,2500A,3150A,4000A; rated short-circuit breaking current:31.5kA,40kA,50kA. CB, DS, ES and CT are enclosed in separated SF6 metal tanks while main busbar uses air insulation. It adopts segregated single-phase tank structure, different from three-phase common tank RHP-245(T). With independent gas compartments, compact layout and factory pre-testing, it is widely used in 220kV transmission substations, large renewable energy booster stations and urban power grid projects.
The voltage covers 40.5kV-145kV and is suitable for scenarios such as power plants, substations, railways, ports, etc. It is particularly suitable for space limited projects such as urban/mountainous substations, renovation of old stations, and rooftop/mobile substations.
It fully complies with IEC international standards. Adopts optimized electric field design with partial discharge ≤3pC, standardized long-life spring mechanism (6000 cycles), and complete five-prevention mechanical interlock system to eliminate misoperation risks. Annual SF6 leakage rate ≤0.5%, ensuring stable and safe grid operation.
