It must be possible to lock the recloser, particularly is maintenance tasks are carried out on the
substation. To this end there are various SIL-D locking and unlocking possibilities:
•
From the HMI
. There is a specific key marked 79, plus a specific signal led, allowing recloser
operation, locking or unlocking it. In order that the command related to the key can run, the
menu must be in standby mode.
•
From the HMI.
This command can be executed from the control menu.
•
From two pulse inputs.
If the substation is equipped with a conventional remote control, two
pulse signals are usually assigned, where one locks the recloser and the other locks it.
•
Via protocol.
This is performed via any means of communication. This is carried out as if it
were a control, and the normal conditions of any control must be met. For example, if we are
operating from the HMI, it is understood that the relay is in local mode, whereby if a
Lock/Unlock command is received via remote control this shall be ignored.
•
From a level input.
In this case the recloser monitors the status of the input. This may be of
use if the company has a handle with a key.
In the first four cases, the equipment stores the lock situation in the non-volatile memory, as the
last control must be know for a possible re-start.
The auto-recloser´s start up is shown in the following figure: There are two stable conditions
here, Standby and Lockout, the other conditions are transient.
