The integrated solution of HECPS–3/5S can satisfy the most demanding pump storage power plants all around the globe. With excellent performance and the highest reliability it covers all basic and extended operational functions.
HECPS-3/5S is a fully integrated system and the individual components can be installed in three different modules: Generator Circuit-Breaker module, 5-phase disconnector module and electrical braking switch.
The 3-phase system with the circuit breaker and disconnector is mounted on a common frame, together with the operating mechanism, supervisory and control equipment. Additional components, such as an earthing switch, starting switch, current or voltage transformer, surge capacitor and surge arrester can be provided integrated and mounted in the phase enclosures. Phase distance can easily be selected to suit the connected busbar.
