Special feature - Single-pole enclosure

L1L2L3

Example 8DA10

Advantage of single-pole enclosure

Exclude phase-to-phase short circuits.

In worst case only phase-to-earth short circuits couldhappen.

Minimizing of fault risks.


© Siemens AG 2008

Special feature - Multiple-Vessel-Principle 8DA10

Busbar and circuit-breaker are single-pole enclosed within different vessels

Measures in case of faults at circuit-breaker or cable connection:

Shut down of the busbar is not necessary

Replacement of panels is possible, while busbar is under high voltage operation

Single-phase enclosure

2 Compartments

6 Vessels

► Shut down is only for the damaged panel necessary

8DA/B10MTBF (1)

The term major failures and minor failures are taken from the CIGRE publication of the work group 13.06 “Reliability of High Voltage Switchgears”.

Definition:

MTBFMeantime between failure

Major failure (MF)Complete failure of a panel which causes the lack of one or more of its fundamentalfunctions.NOTE: A major failure will result in an immediate change in the system operating e.g. the backup protective equipment being required to remove the fault, or will result in mandatory removal from service for non scheduled maintenance (Intervention required within 30 minutes).

Minor failure (mF)Failure of a panel other than a major failure or any failure, even complete, of a constructional element or a sub-assembly which does not cause a major failure of the panel.

MTTFMeantime to failure
