Trigger module, counting module and display module are connected to successively on collection transformer, and the energy-storage module is connected with counting module again
Connect, be electrically connected between trigger module and energy-storage module.
The coil ratio of the accumulation of energy transformer is 500：1.If turn ratio is too big, or too little, to meeting to accumulation of energy
Impact；Mainly impact phenomenon is：A. the energy for meeting condition, required accumulation of energy overlong time are reached；B. it is unable to reach
Normal accumulation of energy voltage, i.e., can not store enough energy.
The high current signals collecting mutual inductor coil turn ratio is 50:1.
The invention also discloses the method for counting of said apparatus, including following content：
1) under circuit normal operating condition, the energy in accumulation of energy transformer collection circuit under normal operating conditions, transmission
To rectification module to supply energy-storage module, energy-storage module is charged to lay in the energy of actuation counter work；
2) when heavy current impact is produced in circuit, high current signals collecting transformer collects the impact signal, and will
To trigger module, trigger module exports a trigger to counting module, counting module identification trigger to the signal transmission
Afterwards, the counter works in discharging the energy stored in energy-storage module to drive counting module, and show heavy current impact
Number of times, so as to complete tally function；
3) while trigger module sends trigger, if the high current of heavy current impact is present always in circuit,
So, trigger module can provide an electric current to energy-storage module, cause energy-storage module to be in side charging, and the state of side electric discharge makes
Obtain energy-storage module to reach after a stable state, the energy that now energy-storage module is stored is enough to counting module work.
Operation principle：
High current (thunderbolt) Counts process：The transformer induced high voltage electric equipment current signal of special purpose energy storage first,
After to sensor current signal rectification, energy storage module stored energy is supplied；When there is high current (thunderbolt) signal to impact
Wait, high current (thunderbolt) signals collecting transformer gets impact energy, by trigger module a trigger is converted into；
Trigger is provided to counting module so that the energy that counting module release energy-storage module is saved, and while releasing energy, is touched
Counting module action is sent out, so as to reach the effect of counting.
Beneficial effect：The invention has the advantages that：
1st, when heavy current impact is counted, by transformer trigger collection signal, trigger module provides dynamic for counting module
Make signal, it is more accurate to signals collecting；
2nd, high current (thunderbolt) impact counts triggering precision and is lifted；Pass through high current (thunderbolt) signals collecting transformer
Lightning strike signals can more accurately be obtained, it is to avoid false triggering, or the phenomenon not triggered occur；
3rd, high current (thunderbolt) impact counting triggering startup threshold value is adjustable；High current (thunder can be adjusted by trigger module
Hit) signal to the effective threshold voltage of counting module, such that it is able to effectively artificially define the model of high current (thunderbolt) signal
Enclose；
4th, it is energy-storage module charging by current transformer induced-current, make use of the characteristic in loop itself, but to loop
Itself not only saves other outside energy supplies without any impact, and also the energy to wasting has certain utilization.
