Embodiment Construction

[0026] Such as Figure 1-2 As shown, the lightning current parameter detection device of this embodiment includes a measurement coil, a voltage regulation module, an optical fiber module and a data acquisition card connected in series in sequence, wherein the measurement coil includes a plurality of parallel coils with different ranges, see figure 2 , the coil includes a linear skeleton 1, and the enameled wire 2 is evenly wound on the linear skeleton 1 to form a hollow single-layer linear coil. Since the transmission of the cable needs to consider the wave process and the input voltage range of the acquisition card, it needs to be increased after the output voltage of the coil. Matching resistors and voltage regulating modules for data collection, specifically, coils are wound according to design parameters (the output voltage of the designed coils is one hundred to several hundred volts and as large as possible), the matching impedance is integrated into the coil, and epoxy ...

Abstract

The invention relates to a lightning current parameter detection apparatus. The lightning current parameter detection apparatus includes measuring coils, a voltage adjusting module, a data acquisition card, an optical fiber module and a computer which are connected in series with one another sequentially; the measuring coil comprises a plurality of parallel coils with different measuring ranges; the coil comprises a linear frame; the linear frame is uniformly wound with enameled wires, so that a hollow sing-layer linear coil can be formed; the measuring coils are connected with the voltage adjusting module and the data acquisition card through a cable; and the data acquisition card transmits signals to the computer through using an optical fiber and by means of the optical fiber module. According to the lightning current parameter detection apparatus, lightning current can be positioned through using a time-difference method and by means of the plurality of measuring coils located at different positions, and therefore, cloud-to-ground lightning density of a small area can be determined, and the comprehensiveness of measurement can be improved.

Description

technical field [0001] The invention relates to a lightning current measuring device, in particular to a detection device and a monitoring and positioning method capable of measuring lightning current parameters and locating the lightning current. Background technique [0002] The traditional magnetic steel rod method, magnetic tape method and Rogowski coil method can only measure the amplitude of lightning current, and the measurement is not simple enough to meet the requirements of real-time monitoring. It can only analyze the amplitude characteristics of lightning current near a specific lightning rod. [0003] Installing magnetic steel rods and other equipment on the transmission line can only detect the lightning density near the transmission line, and the use of this method in other fields requires the cooperation of the power department, and it cannot be widely applied in various fields. Moreover, the magnetic steel bar method is easily affected by the environment, an...
