The Hybrid Solution 3AP1 DTC for 145 and 245 kv siemens.com/answers
Solutions for switchgears and substations fully encapsulated h y b r i d Grade of encapsulation partly encapsulated not encapsulated Dead Tank AIS DCB separate devices DTC SIMOVER Simobreaker partial integration Integration of functions HIS GIS full integration
The Hybrid Idea Proven SF 6 - and air-insulated components that can be combined in different, new ways Optimized investments according to requirements of your individual substation layout Gas insulated components ensure highest availability at minimum maintenance effort Flexibility in confined spaces and extreme environmental conditions, e.g. low temperature applications
Feature Function Benefit Our solution Your benefit resin bushing between components separation of gas compartment Safety current transformer with insulating tower current transformer between circuit breaker and DC/ES Flexibility mix-gas SF 6 /CF 4 capable down to - 55 C Availability mixture of GIS and AIS technology hybrid idea Efficiency position of the drives easy access to the drives Maintenance DC/ES in SF 6, cable connection in IP68 protection against environmental influences Reliability
Hybrid Technology: Dead Tank Compact 3-position disconnector and earthing switch Current transformer Circuit breaker
Optimized Solution AIS DTC GIS total life cycle costs acquisition costs The 3AP1 DTC is the best alternative in consideration of the life cycle Also at highest variability at the integration of functions, the 3AP1 DTC always meet demands for low life cycle costs Minimized life cycle costs at maximized flexibility Costs ownership costs Reliability in accordance with IEC 60300-3-3
Economic Advantage: Life cycle costs Acquisition costs Plant engineering HV primary & secondary equipment Insulators, connectors, conductors Transport, packaging Civil works (earth moving, cable ducts, foundations) Earthing material Supporting structures Control cables Installation, tests and commissioning Costs of ownership Operation costs (running losses, switchyard) Maintenance costs Downtime costs Costs of extension, refurbishment or decommissioning Life cycle costs 145 kv AIS DTC 0 10 20 30 40 50 60 Years Example of an European switching module without: Real estate costs Costs of capital Taxes
H-Layout of a conventional 145 kv (AIS) compared to a DTC solution H-Layout with conventional AIS components (using 5 DTs) H-Layout with 5 DTC switching modules Space reduction of approx. 40%
