Description Parameters Function
Discon-
nector
The disconnector represents
the physical switch in the
SIPROTEC 5 device.
Maximum output time
Seal-in time
Switching-device type
The disconnector replicates
the switch position from the
status of the binary inputs
and also transmits the
command via the binary
outputs.
Control Command processing
Control model
SBO time-out
Feedback monitoring time
Check switching authority
Check if pos. is reached
Check double activat.
blk.
Command checks, commu-
nication with the command
source and with the func-
tion block Disconnector
Inter-
locking
Switchgear interlocking
protection
Interlocking condition (deposited
in CFC)
The Interlocking function-
ality generates the releases
for switchgear interlocking
protection.
The setting values of the parameter can be found in the chapter 6.2.3.2 Application and Setting Notes.
Additional Settings of Disconnector Switching Element
The settings of the disconnector are assigned to the function blocks on the basis of their relevance. Additional
disconnector settings that cannot be directly assigned to one of the 3 function blocks and are identical to the
circuit-breaker settings are available:
