Generator circuit breaker:The HVR-63 GCB is a generator circuit-breaker manufactured by ABB. It is ideal for retrofitting or replacing power plants with unit power of up to 180 MW. It features an open design and compact construction which makes it suitable for open and cubicle installation, as well as for short-circuit rating reaching up to 63 kA.
Generator circuit breaker:Many of todays power plants are more than 20 years old and the need to extend their life time is increasing in todays economic and energy context. For this reason, refurbishment or retrofit is necessary to renew the power plants by replacing the main equipment including the generator circuit breaker An old GCB needs more maintenance than a new one and can cause unscheduled shut downs.
Medium-voltage vacuum circuit breaker:The 12KV VCB (CALIX) is designed for rapid auto reclosing duty with SCADA compatible control system. With an optional features like draw-out type PT, Powerpack, and an Integral earth switch, series trip arrangement for unmanned substation (without auxiliary supply) can be provided.
Medium-voltage vacuum circuit breaker:The CVB 15/08 series is a vacuum circuit breaker which is designed specifically to be considered as the main electrical switch and a device protecting the AC locomotives and its electrical multiple units. The power needed to turn the CVB on is kept through a spring. It only takes a minimum amount of energy to unlock the spring release latch and free the energy stored.
