example 1
[0127] Example 1: 220kV line A set of line protection PCS-931 protection equipment state judgment pressure plate set:
[0128] All soft pressure plates of A set of line protection devices (excluding A set of busbar protection Qiyuan jump soft pressure plates) and hard pressure plates for device maintenance;
[0129] A set of merging unit device maintenance hard pressure plate;
[0130] A set of intelligent terminal device maintenance hard pressure plate;
[0131] In the busbar protection device of A set, the failure of the branch circuit is driven into the soft pressure plate and the SV current is driven into the soft pressure plate;
[0132] B set of line protection reclosing outlet soft pressure plate.
example 2
[0133] Example 2: 220kV A set of busbar protection PCS-915 protection equipment state judgment pressure plate set:
[0134] All soft pressure plates of A set of busbar protection devices (excluding all branch circuit failure input soft pressure plates and SV current input soft pressure plates) and hard pressure plates for device maintenance;
[0135] A set of voltage merging unit device maintenance hard pressure plate;
[0136] A set of busbar protection Qiyuanju soft pressure plate for all line branches;
[0137] The A set of busbar protection failure of all main transformer branches trips the soft pressure plate.
[0138] Enter the input and withdrawal status of this group of soft pressure plates corresponding to the protection device in the input, exit and maintenance states into the advanced application system for intelligent operation and maintenance of secondary equipment; for example: to determine the protection of the RCS-931 protection device for a certain line A set...
