Detailed Explanation Of High-voltage Disconnector: Full Analysis Of Function, Operation And Maintenance

High Voltage Disconnect Switch Operation points
When operating the high-voltage disconnector, a certain operation sequence must be strictly followed. First, during a power outage, the disconnector on the line side should be disconnected first; when power is supplied, the disconnector on the bus side should be closed first. In addition, to ensure the safety of the operation, before operating the disconnector, it is necessary to carefully check whether the circuit breaker is in the disconnected state. Only after confirming that the circuit breaker is in the correct state can the disconnector be operated.
1. Operation points for closing the high-voltage disconnector
When closing the high-voltage disconnector, whether it is through a manual transmission device or using an insulating operating rod, quick and decisive actions should be shown. However, when the closing is about to be completed, it is necessary to control the force and avoid excessive force to prevent damage to the equipment, deformation of the mechanism or breakage of the porcelain bottle. After the operation is completed, be sure to carefully check whether the disconnector has been successfully closed, and confirm the tightness of its contact to ensure that the disconnector can be fully engaged with the fixed contact after closing.
