Zusammenfassung: | The invention discloses a switch control system on an outdoor column. The system comprises a sampling circuit used for acquiring analog signals from a power grid, a signal pre-processing circuit used for pre-processing the analog signals and conversing the analog signals into digital signals, a fault judging unit used for judging faults according to the digital signals, a driving control unit used for driving a switch release separating brake on the outdoor column, a storage unit used for storing waveforms of the analog signals, a human-computer interface used for human-computer interaction, a power source used for supplying power and a wireless communication unit used for remote communication. The switch control system is easy to operate and complete in function, the interface is user-friendly, a switch on the outdoor column can be remotely controlled, and safety of a maintainer is guaranteed. Meanwhile, due to the fault wave recording function, the maintainer can conveniently look for fault causes. |
