Description
Technical field
The utility model relates to a kind of counter, particularly relates to a kind of lightning arrester with wireless data transmission and uses counter.
Background technology
Lightning arrester is a kind of device that is used for monitoring the lightning arrester discharging action with discharge counter.Under normal working voltage, the leakage current that flows through counter is very little, and counter is failure to actuate, and when lightning arrester during through lightning wave, operation ripple and power-frequency overvoltage, big electric current flows through counter, makes the counter running and produces counting.
Lightning arrester utilizes wide range; Lightning arrester all is housed in the high-tension switch cabinet of transformer station, and, adds up lightning arrester running situation when being the count value of discharge counter because transformer station is arranged on the field; Need to send the staff to go each transformer station's statistics; The so not only labour's of labor, and data statistics speed is too slow, and efficient is too low.
The utility model content
The purpose of the utility model promptly is to overcome the deficiency of present technology; Provide a kind of lightning arrester to use discharge counter with wireless data transmission; Automatically send to the server of far-end through the unlimited data transmission module that the carries number of times that to be struck by lightning, make things convenient for staff's real-time statistic data.
The utility model is realized through following technical scheme: a kind of lightning arrester with wireless data transmission is used counter; Comprise lightning arrester action acquisition module, electronic switch, single-chip microcomputer and display; Described lightning arrester action acquisition module comprises a photoelectrical coupler, and the input end of photoelectrical coupler connects the switch contact of the heavy-current discharge protective device on the lightning arrester, and connect a 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, is connected with a communication module on the described single-chip microcomputer, and communication module comprises storage unit and data transmission unit; The input end of storage unit is connected to single-chip microcomputer, and the output terminal of storage unit connects the input end of data transmission unit.
Described wave filter is a low-pass filter.
Described data transmission unit is a modulator-demodular unit.
Described storage unit is a USB storage, connects single-chip microcomputer through USB interface.
The principle of work of the utility model is: when lightning voltage or switching overvoltage are passed through lightning arrester; The signaling switch closing of contact of big 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, and level signal triggers electronic switch behind wave filter and schmitt inverter, and electronic switch output signal carries out analyzing and processing to single-chip microcomputer; Single-chip microcomputer transmits a signal to and shows the thunderbolt number of times on the display; Check that for the staff single-chip microcomputer is also exported a signal in the storer of communication module, storer sends data to the server of far-end after with data storage again through data transmission unit.
The beneficial effect of the utility model is: send to the server of far-end automatically through the unlimited data transmission module that the carries number of times that will be struck by lightning, make things convenient for staff's real-time statistic data, that the utility model also has is simple in structure, count accurate advantage.
