Abstract
The utility model relates to a lightning arrester which not only can release lightning instantly, but also can automatically restore the high-resistance state and not affect the power supply of the user. The lightning arrester comprises varistors R1-R7, inductors L1-L4 and a fuse and is characterized in that the inductor L1 is connected between one end of the varistors R1 and R2; the inductor L2 and one end of the varistor R7 are connected between one end of the varistors R2 and R3; the other ends of the varistors R1, R2 and R3 are spliced and grounded and connected with one end of the varistors R4-R6; the inductor L3 is connected between the other ends of the varistors R4 and R5; and the inductor L4 and the other end of the varistor R7 are connected between the other ends of the varistors R5 and R6. The lightning arrester has the advantages that: firstly, the response speed is high, the lightning can be released instantly, and the high-resistance state can be automatically restored to supply power for the user; and secondly, the circuit has novel, unique and simple structural design and high reliability.
Description
Technical field
The utility model relates to a kind of thunder and lightning abrupt release can either the recovery high-impedance state again automatically and do not influence the lightning protection device that the user powers, and belongs to lightning protection device and makes the field.
Background technology
CN2569411Y, title " a kind of lightning protection device ", it is made up of power lightning protection circuit and signal lighting protection circuit, electrical input connects civil power, the phase line of input AC electricity is connected with the lightning protection device ac output end after two groups of fuse protections, algorithm and current limlitings respectively with zero line, between two groups of fuse protections of phase line and zero line, there is one group of discharge clamp circuit to be connected respectively, has a piezo-resistance to receive zero line from phase line at ac output end with equipotential line; Signal input part is connected with signal output part after algorithm, connects one group of discharge clamp circuit to equipotential line in algorithm place; Signal input, input electric wire exchange ground wire and are connected with equipotential line.Its weak point: the one, circuit structure design complexity, manufacturing cost height; The 2nd, the response time lags behind, and reliability is low.
The utility model content
Purpose of design: avoid the weak point in the background technology, design a kind of thunder and lightning abrupt release can either the recovery high-impedance state again automatically and do not influence the lightning protection device that the user powers.
Design: in order to realize above-mentioned purpose of design.The utility model adopts the anti-thunder and lightning release spare of level Four in the design of circuit structure, when the excessive lightning current of line influence, and the protection of the differential mode of its formation, it is fast to have response speed, and lightning protection is effective, guarantees that power circuit work is unaffected.Its operation principle: when circuit because moment appears in thunder and lightning, during pulse surge, can moment conducting in the time of nanosecond, with the voltage the earth of releasing, after pulse voltage disappears, can recover high-impedance state automatically again, do not influence to the user and power.
