The number of turns, S are the individual pen sectional area of induction coil, and θ is the angle of induction coil plane and the magnetic line of force, and r is induction coil any point
To the distance of the earth lead across center.t0It is the beginning and ending time for generating surge current with t.
Above-mentioned formula 1 completely embodies the energy integral of surge current；t0With t condition start-stop, in " GBT 33588.6-
The 6th part of 2016 lightning protection system component (LPSC): the requirement of lightning stroke counter (LSC) " in requirement be Itc=0.5KA's
8/20 μ s waveform-shaped current (when meeting SPD) can also adjust this value by changing parameter n on Practical Project.
For the parameter of above-mentioned formula 1, the embodiment of the present invention is specifically configured to:
1、μ0It is the magnetic conductivity of vacuum (air), is a constant, so in device provided in this embodiment, thoughts around the home
The skeleton for answering coil will use relative permeability non-magnetizable material for 1, such as PVC etc., to ensure that magnetic conductivity will not be because
