Description
Technical field
The utility model relates to a kind of lightning surge inductor, particularly a kind of lightning surge inductor that adopts tongue tube.
Background technology
When electric current passes through conductor, around conductor, can produce magnetic field, the magnetic direction that produces can be judged with right-hand screw rule, when the electric current by conductor changes, variation also can be ensued in the magnetic field that produces around the conductor, the magnetic field and the relation in direct ratio of the size of current in the conductor that produce around the conductor.
Existing lightning induction device mainly all adopts telefault to respond to, its principle of work is: telefault is put into magnetic field, when the magnetic flux that passes coil changes, the telefault two ends will have induction electromotive force to produce, the size of induction electromotive force is relevant with the magnetic flux that passes coil (being magnetic field intensity), their relations in direct ratio, after the two ends of coil form a closed-loop path, will there be induction current to produce, by induction current being measured the generation of perception thunder and lightning surge.This inductor is in order to guarantee the sensitivity to the lightning current of very little energy, and the inductance value of coil must be done very greatly, and also just so that the number of turns of coil is a lot, volume is very large, will cause no small test for the equipment of limited space; While is owing to this inductor generation is a kind of high-frequency impulse, be difficult to be directly used in control circuit, must after the processing of circuit such as on-off circuit, just can convert switching value to again through the treatment circuit of pressure-limit current-limit, so just can act on control circuit and be connected with microprocessor.So the circuit more complicated of this inductor, the components and parts that adopt are many, cause cost high.
Tongue tube is a kind of special key of magnetosensitive, also claims dry-reed relay.The reed contact that it is made by two or three soft magnetic materials usually, be encapsulated in the glass tube that is filled with inert gas (such as nitrogen, helium etc.) or vacuum, the leaf end of parallel encapsulation is overlapping in the glass tube, and leaves certain interval or be in contact with one another to consist of often opening or normally closed contact of switch.When permanent magnet when the tongue tube, perhaps when forming magnetic field behind the coil electricity above tongue tube reed is magnetized, the contact of reed will induce opposite polarity magnetic pole.Because pole polarity attracts each other mutually on the contrary, when the magnetic force that attracts surpassed the drag of reed, the contact that separates just can adhesive; When magnetic force was reduced to certain value, contact returned to again original state under the effect of reed drag, had so just finished the effect of a switch.
The utility model content
The utility model utilizes tongue tube to the induction of magnitude of field intensity, a kind of lightning surge inductor is provided, it adopts tongue tube as inductor, with solve in the prior art telefault inductor volume large, need supporting a plurality of circuit, circuit components and parts complicated, that adopt to reach the higher problem of cost more.
The technical solution of the utility model is as follows:
A kind of lightning surge inductor, comprise inductor and lightning stroke counter that surge leadage circuit, electric conductor, detection lightning surge occur, wherein said electric conductor is connected with described surge leadage circuit, described inductor be arranged on described electric conductor near, described lightning stroke counter is connected with described inductor, and wherein said inductor is the dry-reed tube switch element.
