Description
Technical field
The utility model relates to scheduler programs to change the electrical monitoring technical field of operating process well, more particularly, to one kind
Disconnecting link mechanical location subsidiary discriminant device.
Background technique
Electric system grid switching operation is substantially the division operation for switching (i.e. breaker), disconnecting link (i.e. disconnecting switch), is passed
The mode of operation of system is dispatcher's long-range division switch, operations staff's division disconnecting link on the spot, that is, scheduling " control switch "
Mode；Currently, grid company is carrying out programming operations, so-called programming operations are exactly to be transitioned into from traditional operation mode
The mode of the mode of dispatcher long-range division switch and disconnecting link, i.e. scheduling " control switch, control disconnecting link ".
Programming operations can effectively improve the efficiency of grid switching operation, and streamline operation reduces caused by human factor
Maloperation risk, while realizing personnel reduction and enlargement；It, can be to operation and maintenance if stroke is insufficient when disconnecting link separating brake or does not act simply
Work belt carrys out great security risk, will lead to electrification when serious and closes the pernicious safety accidents such as earthing knife-switch；If disconnecting link is out of the line when closing a floodgate
Journey is insufficient, it will causes contact resistance excessive, when operation generates heat serious risk.Either traditional operation or programming operations
Whether be in place required to confirmation disconnecting link opening and closing, and judge at least through the instruction of two non-homogeneous or non-same principles, and
And corresponding variation occurs for these instructions, could judge divide-shut brake in place, that is, meets " double confirmations " principle；Current procedureization behaviour
When making, for disconnecting link whether opening and closing in place, only divide-shut brake auxiliary contact signal is uploaded to dispatching desk, only exists by this signal
The adhesion of primary equipment auxiliary contact or disconnecting link opening and closing stroke are not in place and electric position is caused not correspond to situation with mechanical location.
Needing satisfaction " double confirmations " principle, there is still a need for operations staffs to scene artificially to confirm mechanical location simultaneously reporting scheduling, cannot be real
Realize programming operations, and since GIS disconnecting link is closed in the tank body full of SF6 gas, scissor unlimited disconnecting link position
It is too high, by whether being in place visually difficult accurate judgement divide-shut brake.
