Description

technical field

[0001] The invention relates to a five-defense system for a 500kV substation inter-station network, in particular to a five-defense system for a tie line network topology between substations for regional control of a 500kV substation. Background technique

[0002] The "five-proof" locking system is a control system used by the power system to prevent misoperation of switching off during power transmission and distribution in power plants and substations. Mainly limited by technical means: mistakenly entering the live interval; mistakenly pulling and closing the switch; pulling and closing the switch with load;

[0003] The misoperation of the switch switch has repeatedly caused accidents in the power system over the years. It is one of the keys to the safety of power transformation and distribution, and it is also an important part of the power industry's determination to eliminate potential safety hazards. The power system ...
