Description
Technical field
The present invention relates to a kind of counter, particularly relate to a kind of counter for lightning arrester with Wireless Data Transmission.
Background technology
Electricity discharigng counter for arrester is a kind of device of monitoring the lightning arrester discharge action.Under normal working voltage, the leakage current that flows through counter is very little, and counter is failure to actuate, and when lightning arrester passed through lightning wave, operation ripple and power-frequency overvoltage, large electric current flow through counter, produces so that counter operates and counts.
Lightning arrester utilizes wide range, lightning arrester all is housed in the high-tension switch cabinet of transformer station, and because transformer station is arranged on the field, add up lightning arrester running situation when being the count value of discharge counter, need to send the staff to go each transformer station's statistics, so not only expend a large amount of labours, and the speed of data statistics is too slow, efficient is too low.
Summary of the invention
Purpose of the present invention namely is to overcome the deficiency of present technology, a kind of electricity discharigng counter for arrester with Wireless Data Transmission is provided, number of lightning strokes is sent to automatically the server of far-end by the unlimited data transmission module that carries, make things convenient for staff's real-time statistic data.
The present invention is achieved through the following technical solutions: a kind of counter for lightning arrester with Wireless Data Transmission; comprise the 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 the 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; be connected with a communication module on the described single-chip microcomputer; 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.
Described wave filter is low-pass filter.
Described data transmission unit is modulator-demodular unit.
Described storage unit is USB storage, connects single-chip microcomputer by USB interface.
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 the 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 behind wave filter and schmitt inverter; the electronic switch output signal is carried out analyzing and processing to single-chip microcomputer; single-chip microcomputer transmits a signal to and shows number of lightning strokes on the display; check for the staff; single-chip microcomputer is also exported a signal in the storer of communication module, sends data to the server of far-end after storer is stored data by data transmission unit again.
The invention has the beneficial effects as follows: number of lightning strokes is sent to automatically the server of far-end by the unlimited data transmission module that carries, make things convenient for staff's real-time statistic data, that the present invention also has is simple in structure, count accurate advantage.
