RHP-145 Hybrid Gas Insulated Switchgear Drawings

RHP-145-2000A-40kA is ROCKWILL segregated-tank hybrid gas insulated switchgear (HGIS) rated at 145kV, complying with IEC 62271-203, IEC 62271-100, KEMA type tested. It adopts self-blast SF6 circuit breaker with bistable spring or spring-hydraulic operating mechanism. This specific unit is rated 2000A continuous current and 40kA short-circuit breaking current. Available rated current options:2000A,2500A,3150A; breaking capacity options:31.5kA,40kA,50kA. CB, DS, ES and CT are enclosed in separated SF6 metal tanks while main busbar uses air insulation. With independent gas compartments, compact layout and factory pre-testing, it is widely used in 132kV transmission substations, renewable energy booster stations and urban power grid projects.

Frequently asked questions

What is the voltage range and applicable scenarios of RHP type HGIS?

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.

What is the core upgrade of digital RHP type HGIS compared to traditional switchgear?

Full digitalization: Information collection, transmission, and processing are all digital, with fiber optic cables replacing cables;
High compatibility: Following the IEC 61850 standard, devices are interconnected and interoperable;
Easy to expand: New features do not require modification of existing devices, only need to be connected to the network.
