In Fig. 1, when occurring when being struck by lightning, I downlead (ground wire) has transient high-current to pass through, the big current of instantaneous variation induces instantaneous voltage by the closing coil L being wrapped in downlead (ground wire), thunder-and-lightning counter exports the number of times of (OUT) record thunderbolt generation by perception instantaneous voltage, because the service condition of thunder-and-lightning counter limits, its power supply is not adopt civil power usually, but employing powered battery, reason is that mains-supplied system also exists overvoltage pulse being struck by lightning and occurring while, this just needs shock-resistant other consumers of energy force rate of thunder-and-lightning counter high, otherwise be unfavorable for the operation of thunder-and-lightning counter, simultaneously, thunder-and-lightning counter sensor in Fig. 1 is passing through for perception lightning current at present, do not measure its size.
So there is following shortcoming in current implementation method: 1) change difficulty: adopt powered battery, when running down of battery, can only integral replacing, its connecting circuit must be implemented by professional again; 2) function is limited: along with the raising be familiar with thunder and lightning, particularly in order to record the size of surge protector action current, for surge protector safe operation provides Data support.Such as when surge protector is impacted by the lightning current being greater than its setting value, in the urgent need to providing lightning current measuring value, so that timely prompting changing; 3) operational monitoring: as lightning monitoring equipment, the operation of himself and monitoring state are necessary the detection being immediately subject to host computer, guarantee the normal operation of lightning protection facility; 4) install complicated: current thunder-and-lightning counter inductor adopts the mode being wound around ground wire to lay, must disjunction ground wire when doing thunder and lightning record for existing lightning protection facility.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of by the corresponding relation of changes of magnetic field with the induced voltage of its generation, rely on contrast look-up method determination lightning current size rank, and MCU is applied, adopt can at the lightning recorder of the modular structure of OIR simultaneously.
For solving the problem, the present invention adopts following technical scheme:
A kind of online pluggable lightning recorder, comprise lightning recorder body, described lightning recorder body is made up of firm banking and pluggable box, without the need to special maintenance, user can self-changeable, also solve battery maintenance problem simultaneously, lightning induction sensor and MCU is provided with in described lightning recorder body, described lightning induction sensor includes thunder and lightning generation trigger and thunder and lightning flow valuve retainer, described thunder and lightning generation trigger and thunder and lightning flow valuve retainer adopt the mode being wound around ground wire to lay, lightning induction sensor is no longer wound around ground wire and installs, the size of dash current can be measured.
Further; described MCU includes interconnected communication, dead electricity is reported to the police, thunderbolt is reported to the police, impact failure is reported to the police and ageing equipment warning function; utilize internet can remote monitoring thunderbolt occur situation and surge protector operation conditions; immediately impact operation to surge protector overload and make warning, statistics thunder and lightning frequency, when reaching setting value; send to change and report to the police; dead electricity is reported to the police, when abnormal electrical power supply, and instant alarming.
A kind of thunder-strike current measuring method, comprises the following steps:
1) data circuit block diagram is enrolled;
2) obtain lightning impulse current I by data experiments and numeral exports Di, and adjust the number of turns of J and shape carries out test of many times, obtain the experimental data of I and Di relation table;
3) adopt the ladder system of 5KA, by step 2) in I and Di relation table, and to extrapolate when time thunder-strike current according to Di numerical value, thus in triggering export at one, extrapolate when Secondary Shocks thunder and lightning flow valuve by reading Di.
A kind of thunder and lightning generation trigger method for making; use thunder-lightning shock table; with 8/20us waveform; from 1KA-200KA, lightning impulse is done to surge protector; and adopt the mode being wound around ground wire to lay, be close to ground wire and install, by recording the method for Di output and numerical radius; adjustment N, D, L, finally obtain thunder and lightning generation trigger.
The invention has the beneficial effects as follows: owing to being provided with a lightning induction sensor, contain thunder and lightning generation trigger and thunder and lightning flow valuve retainer, change the installation form of inductor simultaneously, thus make inductor no longer be wound around ground wire installation, just can measure the size of dash current; Owing to being provided with MCU, utilize internet can remote monitoring thunderbolt occur situation and surge protector operation conditions, immediately to surge protector overload impact operation make warning; statistics thunder and lightning frequency; when reaching setting value, send to change and report to the police, dead electricity is reported to the police; when abnormal electrical power supply; instant alarming, can in the modular structure of OIR owing to have employed, without the need to special maintenance; user can self-changeable, also solves battery maintenance problem simultaneously.
