Embodiment
Shown in accompanying drawing 1, highly sensitive lightning arrester on-line computing model, comprises signal input module, kernel control module and man-machine interface operational module; Described signal input module is used for the signals collecting to lightning arrestor movement, described kernel control module is used for analyzing the signal that described signal input module gathers, the signal data that man-machine interface operational module is analyzed for recording and show described kernel control module; Described signal input module comprises current transformer (being called for short CT), photoisolator and filter processor, described current transformer is enclosed within for responding to the electric current of cable on cable, the electric current that the rear side that described photoisolator and filter processor are arranged on described current transformer is responded to for the treatment of current transformer;
Described kernel control module comprises single-chip microcomputer and storer, the cable current that described single-chip microcomputer is responded to for the treatment of described current transformer, and described storer is for storing data; Described man-machine interface operational module comprises liquid crystal display and keyboard.
Preferably, described liquid crystal display is LCD1602.
Preferably, described storer is FRAM data-carrier store.
Preferably, adopt MODBUS communication protocol, RS-485 communication mode between each module of this monitor, baud rate is 9600bps.
When lightning arrestor movement, be enclosed within current transformer induction current on cable after photoisolator, filter processor carry out Phototube Coupling, filtering process, single-chip microcomputer is to its signal acquisition process and carry out intellectual analysis, realize process in real time, accurate record, recollect inquiry, clock chip is used for the functions such as time setting.When Analyse of Reject-acting Arrester, be enclosed within current transformer induction current on cable after photoisolator, filter processor carry out Phototube Coupling, filtering process, single-chip microcomputer Real-time Collection Leakage Current effective value is when reaching setting threshold values, liquid crystal display display Leakage Current size malfunction indicator lamp is lighted, contact output alarm signal record trouble time and current value.
The invention solves micro-signal measure, with the problem such as anti-interference, efficiently solving the difficulties of lightning arrester on-line monitoring, is the ideal solution of digitizing, automatic station.
