Lightning arrester utilizes wide range, lightning arrester is all housed in the high-tension switch cabinet of transformer station, and because transformer station is arranged on field, add up lightning arrester running situation while being the count value of discharge counter, need to send staff Qu Ge transformer station statistics, so not only expend a large amount of labours, and the speed of data statistics is too slow, efficiency is too low.
Summary of the invention
Object of the present invention is to overcome the deficiency of present technology, and a kind of electricity discharigng counter for arrester with Wireless Data Transmission is provided, and by the remote-transmission module carrying, number of lightning strokes is sent to automatically to the server of far-end, facilitates staff's real-time statistic data.
The present invention is achieved through the following technical solutions: two teletransmission counter for lightning arresters, comprise lightning arrestor movement acquisition module, electronic switch, single-chip microcomputer and display, described lightning arrestor movement acquisition module comprises a photoelectrical coupler, the input end of photoelectrical coupler connects the switch contact of the heavy-current discharge protective device on lightning arrester, a connect successively wave filter and two schmitt inverters of its output terminal is connected to the trigger point of electronic switch, the signal output part of electronic switch connects the input end of single-chip microcomputer, the output terminal of single-chip microcomputer connects display, on described single-chip microcomputer, be connected with a communication module, communication module comprises storage unit and data transmission unit, the input end of storage unit is connected to single-chip microcomputer, the input end of the output terminal connection data transmitting element of storage unit, on described lightning arrestor movement acquisition module, be also connected with a fiber-optic signal teletransmission unit, the monitoring center in a connection distant place, fiber-optic signal teletransmission unit.
Described wave filter is low-pass filter.
Described data transmission unit is modulator-demodular unit.
Described storage unit is USB storage, by USB interface, connects single-chip microcomputer.
Principle of work of the present invention is: when lightning voltage or switching overvoltage are passed through lightning arrester, the signaling switch closing of contact of large current protective device on lightning arrester, at this moment the receiving end of photoelectrical coupler receives electric signal, and high level signal is changed into low level signal output, level signal triggers electronic switch after wave filter and schmitt inverter, electronic switch output signal is carried out analyzing and processing to single-chip microcomputer, single-chip microcomputer transmits a signal to and on display, shows number of lightning strokes, for staff, check, single-chip microcomputer is also exported a signal in the storer of communication module, storer will send data to the server of far-end after data storage again by data transmission unit.
The invention has the beneficial effects as follows: by the wireless data transfer module carrying, number of lightning strokes is sent to automatically to the server of far-end, facilitate staff's real-time statistic data, this device is also provided with a fiber-optic signal remote-transmission module, when wireless data delivery module breaks down, that the present invention also has is simple in structure, count accurate advantage.
