We are pleased to announce that the GBS Expert Talks 2.0 will take place a second time in Berlin by the end of March 2019: Once again we will be focusing on knowledge and experiences sharing amongst all participants and look forward for interesting discussions. For further information please feel free contact us.
Maximum safety for people and equipment: the HB3 generator switchgear is the world’s first to have a vacuum generator circuit-breaker. For up to 12,500 A with natural cooling and a type-tested switching capacity of up to 100 kA. Thanks to its single-phase encapsulation, short-circuits between the phases are eliminated.
The switchgear can also be smoothly integrated in the generator leads. The phase spacing and diameter of the single-phase, encapsulated IPBs are flexible. The switchgear can also be operated with the overpressure needed for the IPB system.
Everything is focused on your requirements: The HB1 generator switchgear can be customized to individual preferences, entirely according to your needs and in the power range up to 170 MW.
As a particularly compact solution with horizontal busbars, the HB1 is especially suitable for a large number of applications. It is also the ideal solution for tasks in industrial power plants, medium-sized gas, steam and combined cycle power plants as well as solar power plants.
The right fit for your application – for indoor and outdoor installation.
Can be customized to your specific requirements: The VB1 generator switchgear is highly flexible and has an expandable modular concept, making it ideally suited to the power range up to 140 MW.
These features make it especially attractive for power plants with multiple generators or auxiliary feeders for in-house use, excitation or break disconnectors.
Because they require a great deal of switching capability and available space, they are often used in hydroelectric power plants and retrofit projects.
It ensures high plant availability: the VB1-D generator switchgear is suitable for a power range up to 110 MW.
It has vertical busbars and a truck-type design – and thus safe and cost-efficient power generation. Installation, maintenance and repairs can also be performed quickly and easily, thanks to straightforward technology.
In particular, the VB1-D’s compact dimensions make it especially suitable for hydroelectric power applications. The switchgear is expandable, so that multiple-generator applications are possible.
Developed for special requirements: The highly integrated generator switchgear (HIGS), designed specifically for Siemens industrial turbines SGT-600 to SGT-800 as well as for steam turbines SST-400 to SST-600. It can also be adapted for other gas and steam turbines.
With direct connection to the generator, the HIGS combines the conventional generator terminal box with the functionality of a generator switchgear, thus reducing the number of interfaces and saving valuable space.
It is also possible to implement a neutral point treatment and an auxiliary feeder.
When a generator circuit-breaker reaches the end of its service life, it has to be replaced or retrofitted to avoid high maintenance costs, unscheduled downtimes or any safety risks. Therefore Siemens offers state-of-the-art retrofit solutions which are maintenance-free, operated with proven spring-drive mechanism and are designed following the latest standards. Generator circuit-breakers with vacuum switching technology support companies to achieve their sustainability targets because they are environmentally-friendly and contain no toxic decomposition gases. Proven vacuum switching technology makes the difference due to the simplification of operational processes: no gas monitoring and no maintenance efforts. Simply clever. Simply reliable. Simply vacuum generator circuit-breakers from Siemens.
