2.6 Door locking system
To ensure safety and to prevent the doors being opened
unintentionally, all doors are lockable, and the doors of compartments
where medium voltages are present during operation
(
2-15
: 1, 3, 4, 5) are bolted or electromechanically secured.
Additionally, the doors of the medium voltage
compartments have locks with different inserts
than the control compartment door. The different
lock inserts ensure that these doors can only be
opened by personnel authorized to do so.
The covers of the integrated transformer are
bolted.
