مشخصات:
High-performance system solution for demanding power plant applications

HEC 10 GCB is a compact design capable of carrying normal currents up to 29,000 A as well as interrupting short-circuit currents up to 210 kA to protect the most critical generator applications up to 1,500 MW. Based on the well-proven HEC technology with over two decades of successful field experience, it is an enhancement of type HEC 7/8/9 with the following features:

• Fully type-tested exceeding the mandatory requirements of the latest GCB standard IEC/IEEE 62271-37-013

• Equipped with an enhanced passive cooling system design based on the most advanced passive heat pipe technology, patented by Hitachi Energy

• Features HMB-8 from the most reliable* spring operating mechanism family to provide safe performance throughout the entire lifespan of the GCB

• Fully assembled and factory tested, brings substantial savings in time and cost for installation and commissioning

Applications

• Demanding generator applications according to G2** class

Why Hitachi Energy?

• Third generation of HEC technology encompassing almost two decades of Hitachi Energy successful field experience

• Fully type-tested exceeding the mandatory requirements of the latest GCB standard IEC/IEEE 62271-37-013

* Most reliable spring operating mechanism as per paper A3-206 presented at CIGRE 2012

** For GCB with a rated generator-source short-circuit breaking current characterized at contact separation by a degree of asymmetry of 130 percent with the assigned a.c.component (alternating current) of the rated generator-source short-circuit breaking current.
