Description
Technical field
The utility model relates to a kind of electronic information technology lightning protection and detects the thunderbolt equipment and technology, specifically, relates to a kind of passive thunder and lightning acquisition interface.
Background technology
Widespread use along with electronic technology; And fast development of information technology; Electronic equipment has been deep in people's the every field of life and production, and people almost be unable to do without electric equipment every day, from daily televisor, sound equipment and communication facilities to the equipment of industrial product etc.Because various electric equipments adopt integrated circuit mostly, make that the anti-overvoltage capabilities of electronic equipment is all lower, particularly in the more frequent area of thunder and lightning; Spoilage is very large; For this reason, lightning protection device has obtained using particularly electric system, communication system and television broadcasting system widely." lightning protection " is a comprehensive systems engineering, and must be in all its bearings, comprehensive consideration; Take various effective measures, constantly improvement just can obtain effect, even so; Thunderstruck accident is to increase not have to subtract but country is annual; Lose hundreds of millions ofly, one of important reasons wherein lacks the lightning protection measures that corresponding means assessment is taked exactly.
At present; A lot of lightning protection devices has all increased the counting thunder function, but there is unstable situation in major part, as surge current cross low can not enabling counting, frequency too high can misoperation, high energy thunder amplification can crash or circuit damage etc.; Main cause is that thunder and lightning acquisition interface circuit is unstable; Some directly is connected with the detection display circuit, and some interface circuit is subject to thunderbolt and damages, and also has because the high impulse of thunder and lightning causes miscount.
The utility model content
To above deficiency, the utility model provides a kind of counting accurate, and safe and reliable passive thunder and lightning acquisition interface, and it comprises: to the current transformer that carries out inductive pick-up of surge signal; Too high surge signal is carried out the pressure limiting circuit of one-level restriction; The surge signal is carried out the directed rectification circuit of positive-negative polarity; Transfer the thunder and lightning signal after the conversion to accumulator that electric flux is preserved; The voltage stabilizing current-limiting circuit that the too high electric flux of accumulator is carried out filtering; The optocoupler change-over circuit that the surge signal is isolated.
Said voltage stabilizing current-limiting circuit is made up of lightning protection component TVS1, voltage stabilizing diode DZ1, current-limiting resistance R3, resistance R 4 and resistance R 5.
The utility model is compared with prior art and is had the following advantages: for low excessively surge current also enabling counting in time; The voltage stabilizing current-limiting circuit that has lightning protection component TVS pipe can be to restriction in time of the too high thunder and lightning of frequency and counting; Adopt the light-coupled isolation transmission interface, prevented that effectively the thunder and lightning signal from impacting back level counting treatment circuit.
Description of drawings
Fig. 1 is the circuit theory diagrams of the passive thunder and lightning acquisition interface of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further set forth.
As shown in Figure 1; The passive thunder and lightning acquisition interface of the utility model comprises current transformer 1, pressure limiting circuit 2, rectification circuit 3, accumulator 4, voltage stabilizing current-limiting circuit 5 and optocoupler change-over circuit 6; Current transformer 1 is parallelly connected with pressure limiting circuit 2; Insert accumulator 4 through rectification circuit 3 then, accumulator 4 is connected with voltage stabilizing current-limiting circuit 5, and voltage stabilizing current-limiting circuit 5 is connected with optically-coupled change-over circuit 6 counts output.
The above is merely the preferred embodiments of the utility model; The utility model is not limited to above-mentioned embodiment; In implementation process, possibly there is local small structural modification; If spirit and scope that the various changes or the modification of the utility model do not broken away from the utility model, and belong within the claim and equivalent technologies scope of the utility model, then the utility model also is intended to comprise these changes and modification.
