Product Description
Self-compression circuit breakers
252kV SF6 Circuit Breaker
MODEL: LW10B-252
VOLTAGE: 252KV
Circuit Breakers for 72.5 kV up to 800 kV
Circuit breakers are the central part of AIS and GIS switch-gear. They have to meet high requirements in terms of: Reliable opening and closing Consistent quenching performance with rated and short-circuit currents even after many switching operations High-performance, reliable, maintenance-free operating mechanisms. Technology reecting the latest state of the art and years of operating experience are put to use in constant further development and optimization of Siemens circuit break-ers. This makes Siemens circuit breakers able to meet all the demands placed on high-voltage switchgear.
The comprehensive quality system is certied according to DIN EN ISO 9001. It covers development, manufacturing, sales, commissioning and after-sales service.
Circuit breakers for air-insulated switchgear are individual components, and are assembled together with all indi-vidual electrical and mechanical components of an AIS installation on site.
Due to the consistent application of a modular design, all Siemens circuit breaker types, whether air-insulated or gas-insulated, are made up of the same range of compo-nents based on our well-proven platform design (g. 1): Interrupter unit Operating mechanism Sealing system Operating rod Control elements.
The principle of the operating mechanism with charging gear and latching is identical on all types (g. 3, g. 4). Differences between mechanism types are in the number, size and arrangement of the opening and closing springs. Main features at a glance: Uncomplicated, robust construction with few moving parts Maintenance-free Vibration-isolated latches Load-free uncoupling of charging mechanism Easy access 10, 000 operating cycles.
