Be arranged at two row ripple harvesters at these contact system two ends, be respectively used to gather the power information at these contact system two ends and export;
The data source and sink be connected with described row ripple harvester, is encapsulated in the lump in data packet for the power information exported by described row ripple harvester, the described mark of row ripple harvester and the mark of this contact system and sends to described master controller;
After described master controller is used for receiving data packet, therefrom parse the mark of contact system, the mark of row ripple harvester and power information corresponding stored; And the difference between the power information calculating the mark of corresponding same contact system, the mark of different rows ripple harvester, after judging that the difference calculated is greater than setting threshold, the intelligent breaker controlled in described contact system disconnects.
9. Intelligent Selection as claimed in claim 8 jumps device, it is characterized in that, described master controller is disconnected specifically for the intelligent breaker controlled by control bus in described contact system;
Or described master controller, specifically for by communication network, sends open command to the intelligent breaker in described contact system, perform by the intelligent breaker receiving open command the operation disconnecting this intelligent breaker.
10. Intelligent Selection as claimed in claim 8 jumps device, and it is characterized in that, described power information is specially the peak value of the voltage waveform of a more than alternating cycles; And
Described setting threshold is specially 40% of the peak value of rated voltage waveform in described contact system.
