Inevitably, when the DCS is used for unit maintenance, the high-voltage switch cannot be operated remotely. According to the operating procedures, the 6kV high-voltage switch is not allowed to be operated locally, making the operation of the 6kV switch a difficult point in the unit maintenance process.

[0004] Currently, during the unit's maintenance period, the local 6kV switch can only rely on the method of connecting and tripping buttons, resulting in significant cable waste and affecting the safety of local operators.

[0005] Existing technical issues and considerations:
