The new paragon of line fault.
It is faradic battery induction law that the application, which generates faradic principle, and the lightning conducter of two adjacent shaft towers is gone here and there
It connects to obtain the circuit of induced electromotive force generation, the formula of principle Faraday's electromagnetic induction law is expressed：
Wherein, n is coil turn, and Δ φ is flux change amount, and Δ t is to change the time used, and ε is the induced electromotive force generated.
Since the lightning conducter of electric force pole tower is all a conducting wire, then coil turn n=1, induced electromotive force are converted intoSpecifically
Δ φ=Δ BS, the area that wherein S is two lightning conducters to be surrounded with power transmission line, is changeless, if conducting wire is long
Straight, then the electromagnetic intensity B near electrified wire is specially：Wherein K is constant, and I is electric current in conducting wire
Size, r are and conductor spacing.As shown in figure 3, in summary format, can obtain：WhereinIt is exactly that electric current becomes
Rate, if the electric current of transmission line of electricity is expressed as I=ImSin (ω t+ θ), then current changing rate (i.e. the derivative of electric current) is I=Im
Cos (ω t+ θ), and r is variation, is gradual change, can show that specific formula is by integralWherein b is adjacent shaft tower (the first electric force pole tower and third electric force pole tower or second

Distance of a certain phase of transmission line of electricity to lightning conducter farther out.
Upper analysis can obtain according to this, under the periodic action of alternating magnetic field of transmission line of electricity, the magnetic between two lightning-arrest line loops
Flux also does periodical alternation, and then produces induced voltage in lightning-arrest line loop.The induced electricity generated in inductive loop
The size of kinetic potential only with take shelter from the thunder line loop in variation rate of magnetic flux it is related, and the change rate of magnetic flux only with power transmission line AC
The frequency of electricity is related with the loop area of lightning conducter, and the frequency of transmission line of electricity is fixed, and two adjacent shaft tower lightning conducters return
Road surface product is also fixed, therefore the electromotive force size incuded in each circuit is changeless.
In view of communication base station is higher to requirements for power supply power, therefore the induced electromotive force that single inductive loop generates is difficult full
Its requirements for power supply power of foot, therefore module 7 is integrated by electric current, the electric current that two inductive loops of series connection generate is equivalent to concatenation two
A direct voltage source can improve the power and voltage value of DC voltage.And the communication of communication base station transmitting in practice
Signal can meet the demand signals in certain area, i.e., be not that each electric force pole tower is required for carrying additionally communication device, this also makes
