Embodiment 1

[0036] figure 1 It is a structural schematic diagram of the lightning data acquisition device for rocket induced lightning described in the embodiment of the present invention.

[0037] Such as figure 1 As shown, the embodiment of the present invention provides a lightning data collection device for rocket induced lightning, including a lightning launching device 10 and a collection device 20 connected to the lightning launching device 10, and the collection device 20 includes a lightning parameter collector 21 and a lightning image Collector 22;

[0038] The lightning launching device 10 is used for launching rockets to trigger continuous lightning strikes;

[0039] Lightning parameter collector 21, used to collect lightning parameters of continuous lightning strikes;

[0040] Lightning image collector 22, used to collect lightning images of continuous lightning strikes;

[0041]Wherein, the lightning parameter includes lightning current.

[0042] In the embodiment of th...

Embodiment 2

[0055] In the lightning-inducing launching device 10, since the longer the length of the nylon rope, the effect of attracting the lightning is closer to the actual lightning, but the success rate of attracting the lightning decreases accordingly; But the higher the success rate of lightning. According to actual experience, in order to take into account the authenticity and success rate of lightning induction.

[0056] Therefore, the embodiment of the present invention also provides a method for determining the length of the lightning-leading wire. Based on the above-mentioned lightning data acquisition device for rocket-induced lightning, the method for determining the length of the lightning-leading wire includes: when the length of the lightning-leading wire is 800m to 1300m, When the length of the metal connection section of the wire is 0m to 20m, the length of the nylon rope section of the lightning lead wire is 20m to 50m; when the length of the lightning lead wire is 500...

Embodiment 3

[0063] image 3 It is a flow chart of the steps of the lightning data collection method for rocket induced lightning described in the embodiment of the present invention, Figure 4 It is an action diagram of the acquisition device of the lightning data acquisition method described in the embodiment of the present invention.

[0064] Such as image 3 with Figure 4 As shown, the embodiment of the present invention also provides a method of data acquisition of rocket induced lightning, based on the above-mentioned rocket induced lightning data acquisition device, the acquisition method includes the following steps:

[0065] S10. The rocket launcher of the lightning launcher triggers continuous lightning strikes;

[0066] S20. When the lightning strike current reaches the trigger condition for the lightning parameter collector to start working, the lightning parameter collector collects and stores the lightning parameters;

[0067] S30. When the current of the lightning strik...

Abstract

The embodiment of the invention relates to a rocket thunder leading electric data acquisition device and method, and a thunder leading line length determination method. The rocket thunder leading electric data acquisition device comprises a thunder leading emission device and an acquisition device connected with the thunder leading emission device, and the acquisition device comprises a thunder parameter acquisition device and a thunder image acquisition device. According to the rocket thunder leading electric data acquisition device, continuous thunder strike is generated through the thunderleading launching device, the thunder current waveform and the thunder image of the continuous thunder strike are acquired through the thunder parameter acquisition device and the thunder image acquisition device, acquisition of continuous thunder strike parameters is achieved, and data are provided for analyzing the influence of thunder strike on an electric power system. The technical problem that the result of analyzing the harm of lightning stroke to the power system is inaccurate due to lack of continuous lightning stroke parameter acquisition in the prior art is solved. The method for determining the length of the thunder leading wire can guide selection of the thunder leading wire, considers both the thunder leading success rate and the similarity between rocket thunder leading andactual thunder, and improves the thunder leading success rate.

Description

technical field [0001] The invention relates to the technical field of lightning information collection, in particular to a lightning data collection device and method for rocket-induced lightning and a method for determining the length of a lightning-induced wire. Background technique [0002] Lightning strikes will not only cause fault tripping of overhead lines, but also cause damage to equipment in substations. In recent years, continuous lightning strikes have caused frequent damage to circuit breakers, current transformers and arresters, which has become one of the key factors that threaten the stable operation of power systems. [0003] Most of the existing studies on lightning strikes focus on a single lightning strike. According to the lightning statistics measured by the lightning location system, lightning usually contains multiple return strikes, and the amplitude of the main discharge is not necessarily the highest. Since lightning in nature is usually difficul...
